Detailed Description of the Embodiments

[0010] Now, detailed references are provided for the embodiments of the present invention, and examples thereof are illustrated in the accompanying drawings, in which like numbers all represent like elements. To explain the present invention, the embodiments below will be described with reference to the accompanying drawings.

First Embodiment

[0011] According to the first embodiment of the present invention, an electronic seal 11 is provided, for indicating whether a sealed box 2 is opened.

[0012] Figs. 1A and 1B show an L-shaped electronic seal 11 of the present invention. Refer to Figs. 1A and 1B. The electronic seal 11 comprises an integrally formed housing 114, which can be formed by an ultrasonic injection molding process, for example. The integrated housing 114 has the advantage that entering the inside of the housing 114 will inevitably cause a damaged trace on the housing 114. In other words, if access to the inside of the housing 114 is desired, the housing 114 must be opened or damaged, and a trace will be left on the surface of the housing 114 in opening or damaging the housing 114, so inspectors could know the electronic seal has been damaged. The integrated housing 114 can be prevented from being illegally damaged. The integrated housing 114 comprises a front face 115 (corresponding to the second surface) and a back face 116 (corresponding to the first surface). The front face 115 of the housing 114 faces outwards, and the back face 116 of the housing 114 is adapted to contact and fit with the scaled box 2 (corresponding to the attached box). "Fit" refers to that the back face 116 of the housing 114 is substantially complementary with the surface of the box 2 to be contacted, so that after the back face 116 of the housing 114 and the surface of the box 2 contact and fit with each other, no obvious gap is formed between the back face 116 of the housing 114 and the surface of the box 2. Tools such as a blade, a screw driver, etc. or foreign objects cannot enter the back face 116 of the housing 114, so as to prevent the back face 116 of the housing 114 from being damaged.

[0013] The electronic seal 11 further comprises at least one magnet 111 and at least one Hall element 112 paired with the magnet. The magnet and the Hall element arc arranged in the housing 114. The Hall element is adapted to send a warning signal when the housing 114 of the electronic seal 11 is opened.

[0014] A very strong magnetic attractive force is generated when the magnet 111 contacts and fits with the metal box 2 such as a steel container, accordingly, the electronic seal 11 is attached and fixed on the surface of the box 2 of the container. When the electronic seal 11 is fixed on the surface of the box 2, no part of the back face 116 of the housing 114 of the electronic seal 11 can be contacted. The back face 116 of the electronic seal 11 can be contacted only when the electronic seal 11 is pried off the box 2, but in such case, the electronic seal 11 will send a signal indicating the electronic seal 11 has left the box 2.

[0015] The electronic seal 11 comprises at least one magnet 111 and at least one Hall element 112 paired with the magnet. When the magnet 111 is not attached on the metal box 2, the state of the Hall element 112 is "0"; and when the magnet 111 is attached on the metal box 2, the magnet 111 and the Hall element 112 interact with each other, so that the state of the Hall element 112 is "I". After the electronic seal 11 is installed on the box 2, the state of the Hall element 112 is recorded; and when the state of the Hall element 112 changes, the Hall element 112 will send out state information through an antenna. In such a way, an operator can obtain change of the state of the electronic seal 11 and information that the electronic seal 11 is moved. The magnet of the electronic seal is not only adapted to attach the electronic seal to the metal box through magnetic attractive force, but also reflect the state of the electronic seal through interaction with the Hall element.

[0016] Accordingly, as shown in Figs. 3A and 3B, in some cases, a door 20 may be removed by cutting an L-shaped hinge 1, which is welded on the box 2 and connects the door 20 and a side edge 21, for example, of the box 2 (a part of the hinge 1 is welded on the door 20, the other part is welded on a side of the box 2 orthogonal to the door 20), and after illegal movement is completed, the hinge 1 is welded on the box 2 again, so as to avoid that the door 20 is found be opened. In order to prevent the hinge 1 from being damaged, the electronic seal 11 may cover the hinge 1 and protect the hinge 1 from contact or removal, thereby preventing criminal behaviors. Such an electronic seal 11 may be in the shape of L as shown in Figs. 1A and 1B. As shown in Figs. 3A and 3B, the electronic seal 11 covers the hinge 1 in two directions of the L-shaped hinge perpendicular to each other to be attached to the box 2, thereby protecting the hinge 1. Any action damaging the hinge must be performed by removing the electronic seal 11, and illegally removing the electronic seal 11 will trigger warning. Alternatively, the electronic seal 11 may further comprise one or more additional Hall elements 117. The additional Hall elements send a signal indicating the housing 114 is damaged when the housing 114 of the electronic seal 11 is damaged. Due to the additional Hall elements 117, the integrally formed housing 114 cannot be damaged, and the electronic seal 11 itself is monitored. For example, the additional Hall elements 117 are distributed in the electronic seal, and mutually cooperate with magnet matched with the same and arranged in the electronic seal, and when the housing 114 of the electronic seal is damaged, the additional Hall elements 117 send a signal. Favorably, the additional Hall elements 117 mutually cooperate with the magnet 111, which is arranged in the electronic seal and adapted to determine whether the electronic seal leaves the box. Thus, there's no need of arranging additional or special magnet or magnets in the electronic seal, and the magnet 111 can cooperate with the additional Hall elements 117 and at the same time protect the housing of the electronic seal through cooperation with the additional Hall elements 117. Alternatively, the electronic seal 11 may further comprise one or more additional optical elements. The additional optical elements arc arranged at one or more positions in the electronic seal, and these additional optical elements may comprise, for example, a optical sensor. When the electronic seal is damaged and external light irradiates to the inside of the electronic seal, light is sensed by an optical sensor, and then a signal is sent for warning. The optical sensor may comprise an infrared sensor, an ultraviolet sensor, a broadband optical sensor or the like, for example. The optical sensor may be an active optical sensor.

[0017] Alternatively, the electronic seal 11 may further comprise one or more additional optical elements and one or more additional Hall elements 117. Such a structure is favorable and can provide redundant protection.

[0018] The electronic seal 11 comprises two magnets 111 and two Hall elements 112 respectively paired with the two magnets. Two magnets 111 and two Hall elements 112 are respectively disposed at positions adjacent to two end portions of the electronic seal 11, for example, as shown in Fig. 1B. One of the functions of the magnets 111 is fixing the electronic seal 11. The two magnets 111 respectively are arranged adjacent to two ends of the electronic seal 11 may maintain the electronic seal 11 to be fixed on the box 2 in a balancing manner. At the same time, the magnets 111 are also adapted to form the warning together with the Hall elements 112. When the magnet 111 is disposed together with the Hall elements 112 paired with it, and the magnet 111 is attached on the box 2 due to magnetic property, the state of the Hall element 112 is 1; and when the magnet 111 leaves the box 2, the state of the Hall element 112 is changed to be 0, and is sent out. Accordingly, the state of the electronic seal 11 may be determined.

[0019] In the first embodiment, the electronic seal 11 further comprises a magnet locking device 113. The extending and retracting of the magnet 111 is controlled by virtue of the magnet locking device 113. The magnet locking device 113 is adapted to drive the magnet 111 to contact or leave the box 2. The magnet locking device 113 comprises a lock plunger adapted to be operated on the front face 115 (corresponding to the second surface), and a user drives said magnet 111 to contact or leave the box 2 by rotating said lock plunger from the second surface. The second surface is the front face 115 of the housing 114 of the electronic seal 11 facing outwards. Arranging the magnet locking device 113 on the face facing outwards allows an operator to control extending and retracting of the magnet 111 from the front face 115 of the housing 114. For example, if the lock plunger of the magnet locking device 113 is rotated from the second surface, the lock plunger will extend forwards or retract backwards, and the lock plunger pushes or pulls the magnet 111, so as to drive the magnet 111.

[0020] The electronic seal 11 comprises an antenna, for transmitting a signal indicating the state of the Hall element 112.

[0021] The electronic seal 11 comprises a power supply, for providing power for the Hall element 112 and additional Hall elements.

[0022] Preferably, the electronic seal 11 comprises a switch for turning on/off the power supply.

[0023] Preferably, the switch of the electronic seal 11 is a press-in trigger switch, configured to be pressed in for turning on the power supply when the electronic seal 11 is installed on the box 2.

[0024] Alternatively, the electronic seal further comprises an electronic control switch, which can be a power supply switch or other electronic switch in parallel with the press-in trigger switch and controlled by program, thereby ensuring that the electronic seal will not power down in abnormal conditions.

Second Embodiment

[0025] According to the second embodiment of the present invention, an electronic seal 12 is provided, for indicating whether a sealed box 2 is opened.

[0026] Figs. 2A and 2B show a line-type electronic seal 12 of the present invention. Refer to Figs. 2A and 2B. Comparing the line-type electronic seal 12 of the second embodiment with the L-shaped electronic seal 11 of the first embodiment, the housings of the two are different in shape.

[0027] The line-type electronic seal 12 comprises an integrally formed line-type housing 124. The housing 124 comprises a front face 125 and a back face 126. The electronic seal 12 further comprises at least one magnet 121 and at least one Hall element 122 paired with the magnet 121. The magnet 121 and the Hall element 122 are arranged in the housing 124. The Hall element is adapted to send a warning signal when the housing 124 of the electronic seal 12 is opened. The electronic seal 12 further comprises a magnet locking device 123. The extending and retracting of the magnet 121 is controlled by virtue of the magnet locking device 123. The electronic seal 12 may further comprise one or more additional Hall elements 127 and/or one or more additional optical elements. The electronic seal 12 may further comprise an antenna, a power supply, a switch, an electronic control switch and the like.

[0028] As for others not illustrated in the second embodiment, please refer to relevant contents of the first embodiment. For example, reference to relevant description about the housing 114 in the first embodiment may be made with respect to the housing 124 and the front face 125 and back face 126 thereof, except for its different shape from the housing 114. For the magnet or magnets 121, the Hall element or elements 122, the magnet locking device 123, the additional Hall elements 127, the additional optical elements, the antenna, the power supply, the switch, the electronic control switch and the like, reference may be correspondingly made to relevant description about the magnet 111, the Hall element 112, the magnetic locking device 113, the additional Hall elements 117, the additional optical elements, the antenna, the power supply, the switch, the electronic control switch and the like in the first embodiment. Thus, according to the embodiment of the present invention, as shown in Figs. 3A and 3B, when the electronic seal 12 is attached to the door 20, for example, crossing a slot between door leaves of the door 20, the door 20 can not be opened. Because if once the door 20 is opened, the electronic seal 12 cannot well fit with the door 20, a signal indicating the electronic seal 12 leaves the box 2 is sent once the electronic seal 12 leaves the box 2, and then a customs officer or other relevant person, for example, could know the electronic seal 12 is moved and the door 20 is opened. Such electronic seal 12 may be in the shape of a strip, for example, a line-type shape as shown in Figs. 2A and 2B. The door 20 may be closed by enabling the electronic seal to cross the slot between door leaves of the door 20. The electronic seal 12 may further cover a lock 3 for locking the door, as shown in Figs. 3A and 3B.
