Detailed Description of the Embodiments



[0022] The disclosure is described hereinafter in detail by reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features of the embodiments can be combined with each other if no conflict is caused.

Embodiment 1



[0023] In this embodiment, an entrance guard control system is provided. Fig. 1 shows a structure diagram of an entrance guard control system according to Embodiment 1 of the disclosure. As shown in Fig. 1, the system comprises a remote entrance guard management system 100 and a plurality of entrance guard switch devices 102.

[0024] In the above, each entrance guard switch device 102 is configured to acquire a door opening request and a user account which are input by a user who uses a mobile terminal 104, to send the door opening request and the user account to the remote entrance guard management system 100, to receive a check code from the entrance guard management system 100, to check a password input by the user by using the check code, and to execute the operation of opening door if the check is passed; and
the entrance guard management system 100 stores a corresponding relationship between the user account and the mobile terminal identifier of the user, and is configured to receive the door opening request and the user account from the entrance guard switch device 102, to generate a password and a check code corresponding to the user account, and according to the corresponding relationship between the user account and the mobile terminal identifier of the user, to send the password to the mobile terminal 104 corresponding to the user account and to send the check code to the entrance guard switch device 102.

[0025] The related entrance guard system requires a user to carry a key substitute or memory a door opening/closing password and input the password through the keyboard on the entrance guard switch device, so as to implement the operation of opening/closing door. Once the key is lost or the user forgets the password, not only inconvenience is brought to the user, but security hazard is caused too. The above entrance guard control system provided by the embodiment makes full use of the universality of mobile terminals. Hence, during each operation of opening/closing door, the entrance guard management system generates a random password for the user and sends the password to the mobile terminal of the user. Then, the user inputs the received random password on the entrance guard switch device and the entrance guard switch device checks the password. In this way, the user does not need to memory different passwords for different entrance guard switch devices, or to carry a key substitute, but only needs to use the carried mobile terminal to receive the door opening/closing password. Thus great convenience is brought to the user. Moreover, the password or the check code is not stored in the entrance guard switch device, but is generated by the remote entrance guard management system. If the same user operates the same entrance guard switch device at different time, the entrance guard management device generates a random password for the user each time. The password generated each time is different too. Therefore, even if the user loses the password or leaks the password, no security hazard is caused. Thus, the security of the entrance guard control system is greatly improved.

[0026] During the implementation process, the entrance guard management system 100 and the entrance guard switch device 102 can be connected through a wired network, and also can be connected through a mobile communication network. For example, they can be connected by adopting, but not limited to, the Unstructured Supplementary Service Data (USSD) mode.

[0027] Fig. 2 shows a structure diagram of a preferred entrance guard control system according to Embodiment 1 of the disclosure. Preferably, as shown in Fig. 2, the entrance guard control system provided by the disclosure further comprises: a plurality of entrance guard controllers 106, wherein each entrance guard controller 106 manages one or more entrance guard switch devices 102. And each entrance guard controller 106 is configured to receive the user account, the door opening request and the identifier of the entrance guard switch device 102 managed by the entrance guard controller 106, to send the user account, the door opening request, the identifier of the entrance guard switch device 102 and the identifier of the entrance guard controller 106 itself to the entrance guard management system 100 through a mobile communication network, to receive the check code and the identifier of the entrance guard switch device from the entrance guard management system 100, and to send the check code to the entrance guard switch device 102 corresponding to the identifier of the entrance guard switch device 102.

[0028] Preferably, each entrance guard switch device 102 is further configured to acquire a door closing request and a password which are input by the user, to compare the password with a decipher, to execute the operation of closing door if the password and the decipher are consistent, to prompt the user to input the user account if the password and the decipher are inconsistent, and to send the user account, the password, the identifier of the entrance guard switch device and the door closing request to the entrance guard management system 100 through the entrance guard controller 106; and

[0029] the entrance guard management system 100 is further configured to compare the received password with the password previously generated for the door opening request from the user, to notify the entrance guard switch device 102 to execute the operation of closing door if the password received and the password generated are consistent, and to notify the entrance guard switch device 102 not to execute the operation of closing door if the password received and the password generated are inconsistent.

[0030] Preferably, the entrance guard management system 100 stores entrance guard configuration information, user information and entrance guard switching history information locally. The entrance guard configuration information comprises: the identifier of the entrance guard controller 106 managed by the entrance guard system 100, the identifier of the entrance guard switch device bound with each entrance guard controller, and the key corresponding to each entrance guard controller 106. The user information comprises: the user account, the mobile terminal identifier bound with the user account, and the authority of the user account operating the entrance guard switch device 102.

[0031] Preferably, in the condition that the user is a temporary user, each entrance guard switch device 102 is further configured to acquire the mobile terminal identifier and the door opening request which are input by the user, to send the mobile terminal identifier and the door opening request to the remote entrance guard management system 100, to acquire a temporary user account and a temporary password which are input by the user, to check the temporary password by using a temporary check code and to execute the operation of opening door if the check is passed; and the entrance guard management system 100 is further configured to send the mobile terminal identifier and the door opening request to an administrator for authentication, to generate, for the user passing the authentication, the temporary user account, and the temporary password and the temporary check code which are corresponding to the temporary user account, to send the temporary user account and the temporary password to the user terminal 104, and to send the temporary check code to the entrance guard switch device 102.

[0032] During the implementation process, the entrance guard management system 100 and the entrance guard controller 106 can be connected through a wired network, and also can be connected through a mobile communication network. For example, they can communicate by adopting, but not limited to, the USSD mode. The entrance guard management system 100 and the mobile terminal 104 can communicate by adopting, but not limited to, the short message mode. The entrance guard controller 106 and the entrance guard switch device 102 can be connected by adopting, but not limited to, a cable line. If the entrance guard controller 106 and the entrance guard switch device 102 are of the one-to-one corresponding relationship, that is, one entrance guard controller 106 manages one entrance guard switch device 102, these two can be integrated to implement.

Embodiment 2



[0033] During the implementation process, a system administrator, an entrance guard administrator and a user (entrant) need to interact through the entrance guard control system provided by the Embodiment 1, so as to implement the operation of opening/closing door of each entrance guard switch device. This embodiment is to illustrate in detail the preferred entrance guard control system provided by Embodiment 1.

Embodiment 3



[0037] In this embodiment, an entrance guard control method is provided. Fig. 3 shows a flowchart of an entrance guard control method according to Embodiment 3 of the disclosure. As shown in Fig. 3, the method comprises:

Step 302: an entrance guard switch device acquires a door opening request and a user account which are input by a user, and sends the door opening request and the user account to a remote entrance guard management system, wherein the entrance guard management system stores a corresponding relationship between the user account and the mobile terminal identifier of the user;

Step 304: the entrance guard management system responds to the door opening request, generates a password and a check code corresponding to the user account, and according to the corresponding relationship between the user account and the mobile terminal identifier of the user, sends the password to the mobile terminal corresponding to the user account and sends the check code to the entrance guard switch device; and

Step 306: the entrance guard switch device acquires the password input by the user, checks the password by using the check code, and executes the operation of opening door if the check is passed.



[0038] The above entrance guard control method provided by the embodiment makes full use of the universality of mobile terminals. During each operation of opening/closing door, the entrance guard management system generates a random password for the user and sends the password to the mobile terminal of the user. Then the user inputs the received random password on the entrance guard switch device and the entrance guard switch device checks the password. Compared with the conventional art, with the method provided by the embodiment, the user does not need to memory different passwords for different entrance guard switch devices, or to carry a key substitute, but only needs to use the carried mobile terminal to receive the door opening/closing password. Thus great convenience is brought to the user. Moreover, the password or the check code is not stored in the entrance guard switch device, but is generated by the remote entrance guard management system. If the same user operates the same entrance guard switch device at different times, the entrance guard management device generates a random password for the user each time. The password generated each time is different too. Therefore, even if the user loses the password or leaks the password, no security hazard is caused. Thus, the security of the entrance guard control system is greatly improved.

[0039] During the implementation process, the entrance guard management system and the entrance guard switch device can be connected through a wired network, and also can be connected through a mobile communication network. For example, they can be connected by adopting, but not limited to, the USSD mode.

[0040] Preferably, in the condition that the user currently requesting door opening is a temporary user, that is, the information of the temporary user is not registered in the entrance guard management system, Fig. 4 shows a flowchart of a temporary user opening a door according to Embodiment 3 of the disclosure. As shown in Fig. 4, the method further comprises the following steps.
Step 402: the entrance guard switch device acquires the mobile terminal identifier and the door opening request which are input by the user, and sends the mobile terminal identifier and the door opening request to the remote entrance guard management system.
Step 404: the entrance guard management system sends the mobile terminal identifier and the door opening request to an administrator for authentication, generates, for the user passing the authentication, a temporary user account, and a temporary password and a temporary check code which are corresponding to the temporary user account, sends the temporary user account and the temporary password to the terminal of the user, and sends the temporary check code to the entrance guard switch device.

[0041] During the implementation process, after the entrance guard management system receives the mobile terminal identifier and the door opening request sent from an entrance guard switch device, the entrance guard management system can send the mobile terminal identifier and the door opening request to a mobile terminal of the administrator, for the administrator to authenticate and approve. Alternatively, it can be that an examination prompt props up on the portal page of the entrance guard control system for the administrator to authenticate and approve. Preferably, the administrator can be the entrance guard administrator provided by the above embodiment, and also can be the system administrator.
Step 406: the entrance guard switch device acquires the temporary user account and the temporary password which are input by the user, checks the temporary password by using the temporary check code and executes the operation of opening door if the check is passed.

[0042] Preferably, the entrance guard management system can manage a plurality of entrance guard controllers, each of which can control one or more entrance guard switch devices.

[0043] Fig. 5 shows a flowchart of an entrance guard switch device sending a user account and a door opening request to an entrance guard management system according to Embodiment 3 of the disclosure. As shown in Fig. 5, preferably, the entrance guard switch device sending the user account and the door opening request to the remote entrance guard management system comprises the following steps.

[0044] Step 502: the entrance guard switch device sends the user account, the door opening request and the identifier of the entrance guard switch device to an entrance guard controller corresponding to the entrance guard switch device.

[0045] During the implementation process, the managed entrance guard switch devices are numbered uniformly, so that identifiers corresponding to each entrance guard switch device are formed. The entrance guard control system records which entrance guard switch devices are managed by each entrance guard controller specifically, that is, the corresponding relationship between the entrance guard controller and the entrance guard switch device. After the entrance guard switch device receives the account number and the door opening request which are input by the user, the entrance guard switch device carries the identifier of itself in the request message to send to the corresponding entrance guard controller.

[0046] Step 504: the entrance guard controller corresponding to the entrance guard switch device sends the received user account, door opening request and identifier of the entrance guard switch device, and the identifier of the entrance guard controller to the entrance guard management system through a mobile communication network.

[0047] During the implementation process, the entrance guard controller is connected with the mobile communication network and can communicate by adopting, but not limited to, the USSD mode. In order to implement the communication of the USSD mode, the entrance guard controller and the entrance guard management system both need to be provided with an internal mobile communication device, and correspondingly have a Subscriber Identity Module (SIM) card for mobile communication. The identifier of the entrance guard controller can adopt, but not limit to, the SIM card number of the entrance guard controller. After the entrance guard controller receives the user account, the door opening request and the identifier of the entrance guard switch device, the entrance guard controller carries the user account, the door opening request, the identifier of the entrance guard switch device and the card number of the entrance guard controller itself in a password request message to send to the entrance guard management system.

[0048] Preferably, the entrance guard management system stores entrance guard configuration information, user information and entrance guard switching history information locally. The entrance guard configuration information comprises: the identifiers of the entrance guard controllers managed by the entrance guard system, the identifier of the entrance guard switch device bound with each entrance guard controller, and the key corresponding to each entrance guard controller; and the user information comprises: the user account, the mobile terminal identifier bound with the user account, and the authority of the user account operating the entrance guard switch device.

[0049] During the implementation process, both the entrance guard configuration information and the user information mentioned above can be recorded through the WAP portal by the entrance guard administrator, and then be examined and approved by the system administrator.

[0050] Preferably, Fig. 6 shows a flowchart of an entrance guard management system verifying authority according to Embodiment 3 of the disclosure. As shown in Fig. 6, before the entrance guard management system generates the password and check code corresponding to the user account, the method can further comprise the following steps.

[0051] Step 602: the entrance guard management system verifies the validity of the identifier of the entrance guard controller.

[0052] During the implementation process, the entrance guard system resolves a password application message and resolves out the user account, the door opening request, the identifier of the entrance guard switch device and the identifier (card number) of the entrance guard controller respectively. First, the entrance guard system needs to verify whether the identifier (card number) of the entrance guard controller is valid. That is, whether the entrance guard controller has been authorized with a function of applying for a password.

[0053] Step 604: verify the corresponding relationship between the identifier of the entrance guard controller and the identifier of the entrance guard switch device.

[0054] During the implementation process, after the validity of the identifier of the entrance guard controller is verified, the corresponding relationship between the identifier of the entrance guard controller and the identifier of the entrance guard switch device also can be verified. That is, whether the entrance guard switch device is managed by the entrance guard controller.

[0055] Step 606: determine that the user corresponding to the user account has an authority of operating the entrance guard switch device.

[0056] During the implementation process, before the password and the check code are generated for the user, it is needed to perform binding verification on the user account and the identifier of the entrance guard switch device, to verify whether the user has the authority of operating the entrance guard switch device.

[0057] With the above preferred method, before password check is performed, a process of identifier and authority check initiated by the entrance guard management system can be added to further improve the security of the entrance guard control system.

[0058] Preferably, Fig. 7 shows a flowchart of an entrance guard management system generating a password and a check code corresponding to a user account according to Embodiment 3 of the disclosure. As shown in Fig. 7, the entrance guard management system generating the password and check code corresponding to the user account comprises the following steps.

[0059] Step 702: the entrance guard management system randomly generates a password corresponding to the user account.

[0060] Step 704: the entrance guard management system finds a key corresponding to the identifier of the entrance guard switch device locally, wherein the entrance guard management system stores a corresponding relationship between the entrance guard switch device and the key locally.

[0061] Step 706: the entrance guard management system adopts a preset encryption algorithm to generate the check code according to the password and the key.

[0062] Step 708: setting the valid time of the check code to be a threshold time. During the implementation process, the system administrator and the entrance guard administrator determine the threshold time by negotiation. For example, the valid time can be set to be, but not limited to, 1 minute. The entrance guard administrator sets this valid time on the entrance guard switch device.

[0063] With the above preferred method, the entrance guard management system can generate a dynamic password for each user account. Since the password is randomly generated, the password generated for the door opening requests of the same user account at different times is different. Therefore, the user and the password have no regular corresponding relationship, and the security of the entrance guard control system is further improved.

[0064] Preferably, Fig. 8 shows a flowchart of an entrance guard management system sending a check code to an entrance guard switch device according to Embodiment 3 of the disclosure. As shown in Fig. 8, the entrance guard management system sending the check code to the entrance guard switch device comprises the following steps.

[0065] Step 802: the entrance guard management system sends the check code and the identifier of the entrance guard switch device to the entrance guard controller corresponding to the identifier of the entrance guard controller through a mobile communication network.

[0066] Step 804: the entrance guard controller sends the check code to the corresponding entrance guard switch device according to the identifier of the entrance guard switch device.

[0067] Preferably, Fig. 9 shows a flowchart of an entrance guard switch device checking a password input by a user using a check code according to Embodiment 3 of the disclosure. As shown in Fig. 9, after receiving the check code, the entrance guard switch device checking the password input by the user by using the check code comprises the following steps.

[0068] Step 902: verify whether the time difference between the time the password is input and the time the check code is received is beyond the threshold time, so as to verify the time validity of the password.

[0069] During the implementation process, the entrance guard switch device is provided with a timer locally. The entrance guard switch device begins timing when receiving the check code, stops timing when the user completes the input of password, and judges whether the time difference is beyond a preset valid time so as to verify the time validity of the password. If the time difference is not beyond the valid time, the entrance guard switch device performs the following password correctness check. If the time difference is beyond the valid time, the entrance guard switch device prompts to the user that the password is expired and reapplication is required.

[0070] Step 904: adopting a key stored locally to decrypt the check code to obtain a decipher, and comparing the decipher with the password to verify the password.

[0071] During the implementation process, each entrance guard switch device locally stores a unique key which is used for decrypting the received check code, wherein the decryption algorithm is an inverse operation of the encryption algorithm implemented in the entrance guard management system.

[0072] Preferably, the method provided by this embodiment further comprises that the user inputs a door closing request to trigger the entrance guard control system to perform the operation of closing door. Fig. 10 shows a flowchart of an operation of closing door according to Embodiment 3 of the disclosure. As shown in Fig. 10, the process comprises the following steps.

[0073] Step 1002: the entrance guard switch device acquires a door closing request and a password which are input by the user.

[0074] Step 1004: the entrance guard switch device compares the password with the decipher, executes the operation of closing door if the password and the decipher are consistent, prompts the user to input the user account if the password and the decipher are inconsistent, and sends the user account, the password, the identifier of the entrance guard switch device and the door closing request through the entrance guard controller.

[0075] Step 1006: the entrance guard management system compares the received password with the password generated for the door opening request from the user, notifies the entrance guard switch device to execute the operation of closing door if the password received and the password generated are consistent, and notifies the entrance guard switch device not to execute the operation of closing door if the password received and the password generated are inconsistent.

Fig. 11 shows a flowchart of a radio entrance guard system opening a door based on a mobile communication network according to Embodiment 4 of the disclosure. As shown in Fig. 11, the process of opening a door is as follows.

[0077] Step 1101: an entrance guard administrator logs in the entrance guard management system to input the basic information of the entrance guard controller, the entrance guard switch device and the entrant; and the system administrator examines and approves them.

[0078] Step 1102: a temporary entrant presses an "Apply for Entrance" key on the entrance guard; and the entrance guard device prompts to input a cell phone number of the temporary entrant.

[0079] Step 1103: after a temporary entrant inputs the cell phone number, the entrance guard switch device sends to the entrance guard controller an entrance application request, which comprises: an entrance application instruction, an entrance guard number and the cell phone number of the temporary entrant; and the entrance guard controller resolves the request into a USSD message to send to the entrance guard management system, wherein the content of the message is *125#77#1#13966662223#, and the cell phone number of the temporary entrant is 13966662223.

[0080] Step 1104: after receiving the entrance application request, the entrance guard management system finds an administrator of the entrance guard controller and forwards the entrance application request to a bound cell phone in the USSD mode. The administrator of the entrance guard controller confirms whether this application is valid through a phone call, and replies an examination result to the entrance guard management system. The reply comprises the result of whether entrance is allowed and the valid time period of the examination result.

[0081] Step 1105: the entrance guard management system performs processing according to the examination result. If the examination result is approval, the entrance guard management system generates a temporary user account and a dynamic password 123456 for the temporary entrant, and sends the temporary user account and the dynamic password to the cell phone number 13966662223 bound with the temporary user account. And the entrance guard management system generates an entrance guard password 654321 according to the key of the entrance guard switch device and the dynamic password, and sends the entrance guard password to the entrance guard switch device through the entrance guard controller. If the examination result is rejection, the system prompts to the user that the application is rejected through the entrance guard switch device.

[0082] Step 1106: the temporary entrant inputs the temporary user account according to the prompt on the entrance guard switch device; go to Step 1116.

[0083] Step 1107: a common entrant presses an "Open Door" instruction on the entrance guard switch device and inputs a user account according to the prompt on the entrance guard switch device.

[0084] Step 1108: the entrance guard switch device sends to the entrance guard controller the door opening request, which comprises the door opening instruction, the entrance guard number and the user account.

[0085] Step 1109: the entrance guard controller sends a USSD entrance guard door opening request message to the entrance guard management system using an inbuilt cell phone module through the mobile communication network, wherein the content of the message is *125#88#1#1001# and the calling number is the cell phone number (13966661111) of the entrance guard controller.

[0086] Step 1110: the entrance guard management system verifies the validity of the cell phone number (13966661111) of the entrance guard controller. If the cell phone number is valid, the entrance guard management system continues to verify whether the entrance guard number 1 is under the management of the entrance guard controller, and whether the user account 1001 has the authority of opening the entrance guard 1.

[0087] Step 1111: if the verification fails, a door opening failure message is returned to the entrance guard controller. The entrance guard controller forwards the message to the corresponding entrance guard switch device, and the entrance guard switch device prompts to the entrant that the input is wrong.

[0088] Step 1112: after the verification is passed, a dynamic password 123456 is generated for the user account randomly and is recorded in the system. Then the key of the entrance guard switch device is extracted and is encrypted to generate an entrance guard check code 654321, and the valid time period is 1 minute.

[0089] Step 1113: the entrance guard management system sends the entrance guard password 654321 of the entrance guard switch device 1 to the entrance guard controller 13966661111 through a USSD response. Meanwhile, the entrance guard management system sends a short message containing the dynamic password 123456 to the cell phone number (13966662222) bound with the user account of the entrant in the mode of short message. The system records a sending log.

[0090] Step 1114: after receiving the USSD response, the entrance guard controller sends the entrance guard check code to the entrance guard switch device 1 according to the entrance guard number.

[0091] Step 1115: the entrant inputs the dynamic password 123456 contained in the received short message on the entrance guard switch device according to the prompt.

[0092] Step 1116: the entrance guard switch device 1 decrypts the received entrance guard check code by using the preset key, records the reception time, judges whether the time difference between the reception time and the time of the entrant inputting the dynamic password exceeds 1 minute, and compares the decipher with the dynamic password input by the entrant. If the time difference exceeds 1 minute or the password is inconsistent, the entrance guard switch device prompts door opening failure and sends an alarm message to the entrance guard administrator 13966661112. If the time difference is within 1 minute and the password is correct, the entrance guard switch device prompts door opening success and executes the operation of opening door.

[0093] Step 1117: the entrance guard switch device 1 reports a door opening failure or success message to the entrance guard management system through the entrance guard controller, wherein the USSD message is *125#88#1#1001#0#.

[0094] Step 1118: the entrance guard management system records a door opening log and records the state of the entrance guard switch device.
