Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0048] In order to facilitate the inventory and statistics of confidential items stored in the safe, an RFID antenna can be set in the safe. When confidential items need to be stored in the safe, the confidential items can be bound to RFID tags. Binding confidential items and RFID tags refers to binding the physical RFID tag to the confidential object, such as binding the RFID tag to the confidential item by pasting, binding, etc., and binding the RFID tag to the confidential item on the other hand.

[0049] For example, if the confidential item to be stored is a confidential document, the RFID tag can be affixed to the cover of the confidential document, and the association between the identification of the RFID tag on the cover and the file name of the confidential material can be recorded in the system, indicating that the RFID tag and the confidential item are bound to each other.

[0050] When taking inventory statistics, the RFID antenna can emit a radio frequency identification signal. After receiving the radio frequency identification signal, the RFID tag can feedback its own identification. The RFID antenna can determine which RFID tags are stored in the safe according to the identification feedback from the RFID tag. In this way, according to the association between the RFID tag and the confidential items, it can be determined which confidential items are stored in the safe, and the statistical inventory of the confidential items stored in the safe can be realized.

[0051] However, the intensity distribution of the RFID signal sent by the RFID antenna is not uniform. Thus, the RFID signal at certain locations in the safe (e.g., the corners of the safe) may be of low intensity. Thus, the low-intensity RFID signal may not be able to excite the RFID tag and make it unable to return its own identification to the RFID antenna. Thus, the confidential item corresponding to the RFID tag may be missed.

[0052] In order to solve the above problems, the present application provides a safe cabinet and a corresponding antenna control method. The position of the RFID antenna in the safe cabinet can be moved to ensure that the radio frequency identification signal can fully cover the space in the safe cabinet.

[0053] First, the structure of the safe is introduced.

[0054] See also Figure 1 , which is a schematic diagram of the structure of a safe provided in an embodiment of the present application. Figure 1 The implementation shown includes a safe cabinet 10. The safe cabinet 10 includes a cabinet body 11, a controller 12, a motion mechanism 13 and an RFID antenna 14.

[0055] The cabinet 11 is the main structure of the safe 10. The controller 12 is fixed to the cabinet 11 and is connected to the operating mechanism 13 and the RFID antenna 14 respectively through wired or wireless connection. The operating mechanism 13 is fixed, for example, Figure 1 In the implementation shown, the motion mechanism 13 is fixed to the top of the cabinet 11. The RFID antenna 11 is connected to the motion mechanism 13.

[0056] In some possible implementations, the motion mechanism 13 may include a slide rail structure. The slide rail structure includes a slide rail, a slider and a motor. The motor can move the slider on the slide rail. The track of the slide rail structure is fixed to the cabinet 11, and the RFID antenna 14 is fixed to the slide rail of the motion mechanism 13 through the slider of the motion mechanism 13. When the controller 12 generates a control signal, the motor can control the slider of the motion mechanism 13 to move relative to the slide rail of the motion mechanism 13. Accordingly, the RFID antenna 14 will move with the slider in the cabinet 11, so that the radio frequency identification signal emitted by the RFID antenna sweeps through the space inside the safe 10, ensuring sufficient coverage of the radio frequency identification signal.

[0057] In some other possible implementations, the motion mechanism 13 may also include a rotating structure. One end of the rotating structure is fixed to the cabinet 11, and the other end is used to fix the RFID antenna 14. In this way, the controller can rotate the RFID antenna 14 by controlling the rotating mechanism, so that the radio frequency identification signal emitted by the RFID antenna 14 sweeps the space inside the safe 10, ensuring sufficient coverage of the radio frequency identification signal.

[0058] In this way, the RFID antenna is controlled to move inside the safe by the controller and the motion mechanism, so that the radio frequency identification signal can fully cover the internal space of the safe, avoiding missing some corners of the safe. In this way, even if the RFID tag of a certain confidential item is located in the corner of the safe, by moving the RFID antenna, it can be ensured that the radio frequency identification signal emitted by the RFID antenna can cover the RFID tag. In this way, it is ensured that the radio frequency identification signal fully covers the inside of the safe, and all RFID tags in the safe can be scanned to avoid missing.

[0059] exist Figure 1 In the implementation shown, the safe includes one motion mechanism and one RFID antenna. In fact, in the safe provided in the embodiment of the present application, the number of RFID antennas and the number of motion mechanisms are not limited.

[0060] The structure of the safe provided in the embodiment of the present application is introduced above. The following introduces some implementation methods of controlling the RFID antenna in the safe from the perspective of the controller.

[0061] Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0062] See also Figure 2 , Figure 2 A method flow chart of the antenna control method provided in an embodiment of the present application includes:

[0063] S201: Acquire first feedback signals sent by multiple RFID tags.

[0064] In order to count and calculate the confidential items stored in the safe, the controller can send a radio frequency identification signal through the RFID antenna. After receiving the radio frequency identification signal, the RFID tag can generate a feedback signal and transmit the feedback signal. The RFID antenna can collect the feedback signal transmitted by the RFID tag. The controller can count the RFID tags that transmit the feedback signal based on the feedback signals collected by the RFID tags, thereby completing the inventory of the confidential items.

[0065] That is to say, after determining that it is necessary to conduct a statistical inventory of the confidential items stored in the safe, the controller can first control the RFID antenna to send a radio frequency identification signal and obtain feedback signals sent by multiple RFIDs. In the antenna control method provided in the embodiment of the present application, the controller can control the RFID antenna to send radio frequency identification signals multiple times in a statistical inventory. In order to distinguish different radio frequency identification signals, the radio frequency identification signal sent in step S101 is referred to as the first radio frequency identification signal. Accordingly, the feedback signal generated and returned by the RFID tag based on the first radio frequency identification signal can be referred to as the first feedback signal. The first radio frequency identification signal is a radio frequency identification signal sent by the RFID antenna for all RFID tags.

[0066] The following describes how to implement controller-triggered statistical inventory.

[0067] Specifically, the conditions for automatically triggering the statistical inventory can be pre-set in the controller. When the conditions are met, the controller can obtain the target moving position and control the motion mechanism to move the RFID antenna. For example, the time period for the statistical inventory can be pre-set so that the controller can perform statistical inventory periodically. For another example, the logic of automatically performing statistical inventory after the safe door is closed can be set. In this way, after detecting that the safe door is closed, the controller can actively trigger the statistical inventory, thereby controlling the RFID antenna to transmit the first video recognition signal.

[0068] For example, the administrator can trigger the statistical inventory operation through a terminal device (such as a computer, mobile phone or tablet computer, etc.). The terminal device can generate a statistical inventory instruction based on the statistical inventory operation and send it to the controller of the safe. The safe can include an instruction receiving device such as an antenna. The instruction receiving device can obtain the scanning instruction and send it to the controller. The controller can perform statistical inventory based on the scanning instruction.

[0069] For another example, a module for triggering operation such as an operation panel or an operation button can be set on the safe. The user can manually trigger a scanning instruction through the operation panel or the operation button to enable the controller to count the confidential materials stored in the safe.

[0070] S202: Determine a target position according to a plurality of first feedback signals.

[0071] After obtaining a plurality of first feedback signals, it can be determined whether the RFID antenna needs to be moved. If necessary, the target position can be determined based on the plurality of first feedback signals. The target position is the position to which the RFID antenna needs to be moved. The target position is associated with a motion mechanism for moving the RFID antenna. For example, if the motion mechanism is a slide rail, the target position can be a position coordinate on the slide rail. If the motion mechanism is a rotation mechanism, the target position can be an angular coordinate.

[0072] Optionally, the target position may also be a position calculated according to the signal strength of the first feedback signal. Accordingly, the controller may count the signal strength of each first feedback signal respectively, thereby determining the target position according to the signal strength of the first feedback signal.

[0073] For example, in one implementation, the signal strength of each first feedback signal can be obtained first. Then, the signal strength of each first feedback signal and the signal strength threshold can be compared, and the first feedback signal whose signal strength is less than the signal strength threshold can be determined as the target first feedback signal. Among them, the signal strength threshold is a pre-set threshold used to determine whether the strength of the feedback signal is too low. The signal strength of the target first feedback signal is lower than the signal strength threshold, indicating that the signal strength of the target first feedback signal is insufficient. In this way, the signal strength of the feedback signal emitted by other RFID tags around the RFID tag that emits the target first feedback signal may also be low, or even unable to be received by the RFID antenna. In this way, the RFID antenna is moved to the position corresponding to the target first feedback signal and then the radio frequency identification signal is emitted. These RFID tags can receive radio frequency identification signals with sufficient strength, thereby feeding back feedback signals with sufficient signal strength. In this way, it is possible to avoid missing RFID tags in the safe, thereby comprehensively counting and counting confidential items.

[0074] For another example, in another implementation, the signal strength of each first feedback signal can be obtained, and then the average signal strength of multiple positions can be calculated respectively. If the average signal strength of a certain position is low, it is considered that the radio frequency identification signal emitted by the RFID antenna at the current position cannot well cover the RFID tag at this position. In this way, the position with the low average signal strength can be determined as the target position. Optionally, the position with the lowest average signal strength can be determined as the target position. Alternatively, the position with an average signal strength lower than a preset average signal strength threshold can be determined as the target position. In this way, the average signal strength of the feedback signal from the RFID tag at the target position is insufficient, indicating that the radio frequency identification signal emitted by the RFID antenna may not allow the RFID tag at the target position to emit a feedback signal with sufficient strength. The signal strength of the feedback signal emitted by the RFID tag at the target position may also be low, or even unable to be received by the RFID antenna.

[0075] S203: Control the motion mechanism to move the RFID antenna to the target position.

[0076] After determining the target position, the controller can control the motion mechanism to move the RFID antenna to the target position. For example, if the motion mechanism includes a slide rail system, the controller can control the motor to move the slider to the position coordinate corresponding to the target position; if the motion mechanism includes a rotation system, the controller can control the motion mechanism to rotate the RFID antenna to the angle corresponding to the target position.

[0077] Specifically, the current angle position of the RFID antenna can be obtained by a sensor, and then based on the current angle position and the target angle position, the motion mechanism is controlled to move the RFID antenna to the target angle position. Optionally, a control algorithm such as PID can be used to control the motion mechanism, so as to accurately move the RFID antenna to the target position.

[0078] S204: Send a second radio frequency identification signal through the RFID antenna, and obtain a plurality of second feedback signals.

[0079] After instructing the RFID antenna to move to the target position, the controller can control the RFID antenna to send a radio frequency identification signal again and obtain feedback signals emitted by multiple RFID tags. In the embodiment of the present application, the radio frequency identification signal emitted in step S204 is referred to as a second radio frequency identification signal, and the feedback signal returned by the RFID tag based on the second radio frequency identification signal is referred to as a second feedback signal.

[0080] S205: Taking inventory and counting of the RFID tags in the safe according to the first feedback signal and the second feedback signal.

[0081] When taking inventory and counting the confidential items stored in the safe, statistics can be performed based on the first feedback signal and the second feedback signal. Since the positions of the antenna when transmitting different radio frequency identification signals are different, the RFID tags with higher signal strength in the first feedback signal and the second feedback signal are also different. Therefore, based on the first feedback signal, statistics can be performed on multiple RFID tags corresponding to the initial position of the RFID antenna, and based on the second feedback signal, statistics can be performed on multiple RFID tags corresponding to the target position. In this way, according to the feedback signal sent by the RFID tag, the RFID antenna can be controlled to transmit radio frequency identification signals at different positions, so as to comprehensively take inventory of the confidential items stored in the safe.

[0082] The present application provides an antenna control method, device, safe cabinet and storage medium. Among them, the safe cabinet includes a cabinet body, a controller, a motion mechanism and an RFID. The confidential materials stored in the safe cabinet can be associated with the RFID tag. The controller can transmit a radio frequency identification signal through the RFID antenna, and identify the RFID tag in the safe cabinet based on the feedback signal returned by the RFID tag, and complete the statistical inventory of the confidential materials.

[0083] Moreover, during the process of statistical inventory, the controller can control the RFID to first send a radio frequency identification signal and receive the corresponding first feedback signal. Based on the actual situation of the first feedback signal, the controller can determine the target position and move the RFID antenna to the target position through the motion mechanism. The RFID antenna can send a second radio frequency identification signal at the target position. By receiving the second feedback signal fed back by the RFID tag based on the second radio frequency identification signal. Since the first radio frequency identification signal that triggers the first feedback signal and the second radio frequency identification signal that triggers the second feedback signal are sent by the RFID antenna at different positions, the first radio frequency identification signal and the second radio frequency identification signal can cover different areas in the safe, thereby comprehensively scanning the RFID tags stored in the safe. In this way, statistical inventory is performed based on the first feedback signal and the second feedback signal, and the RFID tags stored in the safe can be comprehensively counted to avoid omissions.
