Detailed Description of the Embodiments



[0018] It is to be noted that in the case of no conflict, the features in the embodiments and the embodiments in the present invention may be combined with each other. The present invention will be illustrated below with reference to the drawings and in conjunction with the embodiments in detail.

[0019] In order to make those skilled in the art better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. On the basis of the embodiments of the present invention, all other embodiments obtained on the premise of no creative work of those skilled in the art fall within the scope of protection of the present invention.

[0020] According to an embodiment of the present invention, an activation control method for a railway train is provided.

[0021] Fig. 1 is a flowchart of an activation control method for a railway train according to an embodiment of the present invention. As shown in Fig. 1, the method includes the steps as follows.

[0022] At step S101, at least one activation request sent by at least one master controller of the railway train is received.

[0023] As an optional example, in the activation control method for a railway train provided by the embodiment of the present invention, a condition of triggering at least one master controller of the railway train to send at least one activation request includes that: when a key of the master controller of the railway train is at an ON position, the master controller of the railway train sends at least one activation request.

[0024] In addition, the condition of triggering at least one master controller of the railway train to send at least one activation request may also be that: when the master controller of the railway train receives a target instruction and after the target instruction is validated, the master controller of the railway train sends at least one activation request.

[0025] It is to be noted that the above target instruction may be a voice instruction, that is, after the voice instruction passes a sound ray validation, the master controller of the railway train sends at least one activation request. In addition, the above target instruction may also be a target fingerprint, that is, after the target fingerprint is validated, the master controller of the railway train sends at least one activation request. In addition, the above target instruction may also be a target iris, that is, after the target iris is validated, the master controller of the railway train sends at least one activation request. No specific limitations are made herein.

[0026] For the multiple examples, optionally, in the activation control method for a railway train provided by the embodiment of the present invention, the operation that at least one activation request sent by at least one master controller of the railway train is received may be that: at least one activation request sent by at least one master controller of the railway train is received, wherein the at least one activation request may be a network signal or a circuit signal.

[0027] In order to reduce the potential safety hazard of the railway train, optionally, in the activation control method for a railway train provided by the embodiment of the present invention, before at least one activation request sent by at least one master controller of the railway train is received, the method further includes that: state information of the railway train is received, wherein the state information is used for representing a current state of the railway train; and when it is determined that the state information of the railway train satisfies a preset condition, the step of receiving at least one activation request sent by at least one master controller of the railway train is continuously performed.

[0028] It is to be noted that before at least one activation request sent by at least one master controller of the railway train is received, it is necessary to preliminarily judge the state information of the railway train, in order to determine whether various statees of the railway train meet the safety standard. That is, only when various statees of the railway train meet the safety standard, the step of receiving at least one activation request sent by at least one master controller of the railway train is further performed. Thus, the technical effect of multiply guaranteeing the safe drive of the railway train is achieved, thereby avoiding the problem of potential safety hazard of the railway train.

[0029] As an optional example, the state information includes at least one of the following: passenger capacity of the railway train, an electrical state of the railway train, or the like.

[0030] At step S102, a number of at least one master controller sending the at least one activation request is determined.

[0031] It is to be noted that a condition of triggering at least one master controller of the railway train to send at least one activation request includes that: when a key of the master controller of the railway train is at an ON position, the master controller of the railway train sends at least one activation request. The operation that a number of at least one master controller sending the at least one activation request is determined may be that: counting is started from where keys of all master controllers of the railway train are at OFF positions, that is, after keys of all master controllers of the railway train are at OFF positions, the number of corresponding master controllers that receive the at least one activation request is determined.

[0032] In addition, the condition of triggering at least one master controller of the railway train to send at least one activation request may also be that: when the master controller of the railway train receives a target instruction and after the target instruction is validated, the master controller of the railway train sends at least one activation request. The operation that a number of at least one master controller sending the at least one activation request is determined may be that: when the railway train receives a trigger signal of a reset button, a number of at least one master controller sending the at least one activation request after the trigger signal is received starts to be determined.

[0033] At step S103, when there are a plurality of master controllers sending the at least one activation request, the railway train is controlled to perform an emergency braking.

[0034] That is, after at least one activation request sent by at least one master controller is received, at least one activation request sent by another master controller is also received, the at least one activation request sent by the second master controller is ignored, and the railway train is controlled to start an emergency braking, thus avoiding the situation that multiple master controllers have a permission to control the railway train simultaneously, or avoiding the situation that the second master controller is automatically endowed with a permission to control the railway train after the first master controller closes control over the railway train, so as to achieve the technical effect of guaranteeing the safe drive of the railway train.

[0035] Further, after the railway train is controlled to perform an emergency braking, in the activation control method for a railway train provided by the embodiment of the present invention, the method further includes that: when it is determined that the key of each master controller of the railway train is at a OFF position, the step of receiving at least one activation request sent by at least one master controller of the railway train is continuously performed.

[0036] That is, after the railway train has an emergency braking due to the fact that multiple master controllers send the at least one activation request, only when keys of the multiple master controllers are provided at OFF positions, the at least one activation request sent by the master controllers may be received again. That is, only when keys of multiple master controllers are at OFF positions, the at least one activation request sent by the master controllers can be received, and only the master controller uniquely sending the at least one activation request has a permission to control the railway train.

[0037] At step S104, when there is one master controller sending the at least one activation request, it is determined that a target master controller has a permission to control the railway train, wherein the target master controller is a unique master controller sending the at least one activation request.

[0038] It is to be noted that when it is determined that there is one master controller sending the at least one activation request, it is determined that the master controller uniquely sending the at least one activation request has a permission to control the railway train; and after the at least one activation request sent by one or more master controllers is received at this time, the railway train is controlled to perform an emergency braking.

[0039] In order to ensure that the master controller has a permission to control the railway train, optionally, in the activation control method for a railway train provided by the embodiment of the present invention, when there is one master controller sending the at least one activation request, the operation that it is determined that a target master controller has a permission to control the railway train includes that: when there is one master controller sending the at least one activation request, a circuit signal is sent to a target relay, the target relay corresponds to the target master controller; and after the target relay receives the circuit signal, a communication connection between the target master controller and a control communication network of the railway train is established, the control communication network is used for transmitting at least one control signal of the railway train.

[0040] It is to be noted that the control communication network may be a circuit communication network, or a network communication network, or a combination of the circuit communication network and the network communication network, which is not specifically limited herein.

[0041] It is to be noted that the target relay is used for establishing a communication connection between the target master controller and the control communication network of the railway train according to the received circuit signal, and each master controller has a corresponds relay.

[0042] Fig. 2 is a circuit diagram of an optional activation control method for a railway train according to an embodiment of the present invention. P4 in the figure represents a miniature circuit breaker of at least one master controller, MC in the figure represents the master controller, REV (F, R) in the figure represents a key (forward, backward), CPU in the figure represents an internal communication board card of the master controller, CMS in the figure represents a network system local control element, ACR in the figure represents an activation control relay, TW26 in the figure represents a train line for train activation, and a TCMS system in the figure represents a train control and monitoring system. As shown in Fig. 2, TCMS is connected to REV (F, R) and ACR, and when TCMS receives a REV (F, R) signal and receives only one REV (F, R) signal, TCMS triggers ACR, wherein as an optional example, a circuit signal indicating that TCMS triggers ACR may be: current of 37.5V 1000mA.

[0043] Fig. 3 is a state transition diagram of an optional activation control method for a railway train according to an embodiment of the present invention. As shown in Fig. 3, when a master controller is in a non-activated state (OFF) and keyed on, the activation request (Lead Requested) will be sent out, and the railway train will evaluate the request: if this is the only one master controller sending out the Lead Request, railway train will approve the request and the master controller will be switched to activated state (ON). If this is not the first master controller sending out the Lead Request, railway train will deny the request (Request Denied) and the master controller will stay on non-activated state (OFF).

[0044] It is to be noted that in order to reduce the potential safety hazard of the railway train, after the target relay receives the circuit signal, the method further includes that: a train line of the railway train is powered on; and when it is determined that the train line of the railway train has been powered on, target information is fed back, the target information is used for representing that the target master controller has controlled the railway train.

[0045] That is, after the train line of the railway train is powered on, the power-on condition of the train line of the railway train is continuously detected, and it is detected whether the target master controller has controlled the railway train. When the train line of the railway train is normally powered on and the target master controller has normally controlled the railway train, the detection result is fed back. The control information of the railway train can be mastered in time, thus avoiding an accident.

[0046] As an optional example, when the railway train is normally powered on, the target master controller has been already permitted to control the railway train.

[0047] As an optional example, the target information further includes: a connection condition of the control communication network of the railway train, wherein the connection condition at least includes: a connection device of the control communication network.

[0048] The activation control method for a railway train provided by the embodiment of the present invention includes that: at least one activation request sent by at least one master controller of a railway train is received; a number of at least one master controller sending the at least one activation request is determined; when there are a plurality of master controllers sending the at least one activation request, the railway train is controlled to perform an emergency braking; and when there is one master controller sending the at least one activation request, it is determined that a target master controller has a permission to control the railway train, wherein the target master controller is a unique master controller sending the at least one activation request. The problem in the related art of potential safety hazard of a double-vehicle activation processing method is solved. Thus, the effect of guaranteeing the safe drive of the railway train is achieved.

[0049] It is to be noted that the steps shown in the flowchart of the drawings may be executed in a computer system including, for example, a set of computer-executable instructions. Moreover, although a logic sequence is shown in the flowchart, the shown or described steps may be executed in a sequence different from the sequence here under certain conditions.
