[0019] Due to the lack of supervision during the transportation of goods, the customs lock may be cut off, opened and then locked again, and the goods are still at risk of being stolen or adding prohibited items. Therefore, a customs lock, a customs lock cutting detection method, a device and a storage medium are needed to detect the status of the customs lock, thereby improving the security of the customs lock.

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0021] An embodiment of the present invention relates to a customs lock, comprising: a lock cap, a metal lock core and a lock body; the lock cap comprises a buckle structure and a radio frequency tag; the buckle structure is used to control the opening and closing state of the customs lock, and the radio frequency tag comprises tag information; the lock cap is connected to the lock body through the metal lock core; the lock body comprises a first radio frequency transceiver module and a baseband chip; wherein the baseband chip is connected to the first radio frequency transceiver module; the first radio frequency transceiver module is also connected to the metal lock core, and obtains the tag information through the metal lock core when the buckle structure is closed. The customs lock comprises a lock cap and a lock body connected to the metal lock core, and the lock cap comprises a buckle structure and a radio frequency tag for controlling the opening and closing of the customs lock. When the buckle structure is closed, the tag information of the radio frequency tag can be transmitted to the first radio frequency transceiver module in the lock body connected to the baseband chip through the metal lock core, so that the closing state of the customs lock can be judged by whether the lock body can detect the tag information of the radio frequency tag. When the radio frequency tag information of the customs lock cannot be scanned, it can be judged that there is a risk of the goods, so that the abnormal situation of the customs lock can be detected in time, and the safety of the customs lock is improved. The implementation details of the customs lock of the embodiment of the present invention are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0022] like Figure 1As shown, the customs lock in the embodiment of the present application includes a lock cap 1, a metal lock core 2 and a lock body 3. The lock body 3 includes a first radio frequency transceiver module 302 and a baseband chip 301; the baseband chip 301 is connected to the first radio frequency transceiver module 302. The baseband chip 301 refers to a chip used to synthesize a baseband signal to be transmitted, or to decode a received baseband signal. When transmitting, the baseband chip 301 encodes the data signal into a baseband code for transmission; when receiving, the baseband chip 301 decodes the received baseband code into a data signal, which is mainly used to complete the information processing function.

[0023] The lock cap 1 includes a buckle structure 101 for controlling the opening and closing of the customs lock, and a radio frequency tag 102 with tag information.

[0024] Specifically, the radio frequency tag 102 is an RFID tag or an NFC tag. NFC (Near Field Communication) tag is a short-range wireless communication technology, a special form of RFID, usually used for more interactive and short-range data exchange. Since NFC tags are usually passive and have no power supply, they need to obtain energy by approaching an NFC reader (such as a smart phone); Radio Frequency Identification (RFID) is a technology used to automatically identify and track objects. It is a type of automatic identification technology. It uses wireless radio frequency to perform non-contact two-way data communication, and uses wireless radio frequency to read and write electronic tags or radio frequency cards, so as to achieve the purpose of identifying targets and data exchange. RFID tags contain microchips and antennas. RFID tags communicate through radio waves. The antenna of the RFID tag receives signals from the RFID reader and sends the stored information back to the RFID reader. RFID technology relies on electromagnetic waves and does not require physical contact between the two parties. Each RFID tag is unique. Through the one-to-one correspondence between the RFID tag and the customs lock, the situation of the customs lock can be clearly tracked. Therefore, RFID is suitable for large-scale automatic identification and tracking systems, while NFC is more suitable for applications that require short distances and strong interactivity. In the embodiments of the present application, RFID tags are preferably used.

[0025] The first RF transceiver module 302 is also connected to the metal lock core 2, and obtains the tag information through the metal lock core 2 when the buckle structure 101 is closed. The RF tag 102 information is transmitted through the metal lock core 2 itself, thereby reducing the cost of communication connection.

[0026] The tag information of the RFID tag 102 can be transmitted to the lock body 3 through the metal lock core 2. Since the lock core itself is a metal conductor and can transmit and receive electromagnetic waves, the tag information of the RFID tag 102 in the lock cap 1 can be transmitted to the lock body 3 through the metal lock core 2. Further, in one embodiment, the lock body 3 includes an antenna tuning module 303, which is arranged between the connection line between the first RFID transceiver module 302 and the metal lock core 2, and the first RFID transceiver module 302 is connected to the metal lock core 2. The antenna tuning module 303 is a printed circuit board (PCB) printed with an antenna. The antenna tuning module 303 adjusts the resonant frequency through the PCB to scan and detect the tag information of the RFID tag 102, thereby changing the antenna resonant frequency, and scanning the RFID tag 102 in the lock cap 1 to detect the state of the customs lock. The antenna tuning module 303 can flexibly change the resonant frequency of the antenna, and can be applied to different RF technology fields to transmit and receive different RF signals, thereby improving the flexibility of RF transceiver of the customs lock.

[0027] In one embodiment, the metal lock core 2 is also connected to the sub-connecting rod 4; the lock body 3 also includes a microcontroller unit 304 (MCU) connected to the baseband chip 301; the microcontroller unit 304 is connected to the sub-connecting rod 4; the microcontroller unit 304 controls the switch of the buckle structure 101 through the sub-connecting rod 4; and is used to transmit the tag information of the radio frequency tag 102 to the microcontroller unit 304. When the lock cap 1 is buckled on the lock core, the MCU can detect the buckle state through the sub-connecting rod 4, and the first RF transceiver module 302 can read the tag information of the RF tag 102 and bind it; when the buckle structure 101 is closed and can read the tag information of the RF tag 102, the customs lock is in a correct locked state; if the lock body 3 is damaged, the buckle structure 101 is closed but the first RF transceiver module 302 cannot scan the tag information, and the goods are at risk of being stolen and adding contraband items; if the buckle structure 101 is not closed, the customs lock is not locked, and the first RF transceiver module 302 cannot detect the tag information. When the customs lock is not locked correctly, the goods are at risk of being stolen and adding contraband items. In addition, the automatic opening and closing control of the customs lock through the MCU can improve security, reduce the procedures for manual inspection and sealing, and reduce the time for manual inspection and unlocking, thereby improving the acceptance efficiency of goods.

[0028] Furthermore, in order to improve the security of the customs lock, the customs lock can be additionally provided with a positioning function and a communication function. In one embodiment, the lock body 3 further includes: a positioning module 305 and a second radio frequency transceiver module 306; the positioning module 305 is used to locate the position information of the lock body 3; the second radio frequency transceiver module 306 is used to report an abnormal situation when the lock body 3 is detected to be damaged; the baseband chip 301 is also connected to the positioning module 305 and the second radio frequency transceiver module 306 respectively. Specifically, the positioning module 305 is a GNSS positioning module 305, and a positioning module 305 of other positioning systems can also be selected, which is not limited in this application. When the customs lock is not locked correctly, the first radio frequency transceiver module 302 cannot scan the tag information, and the position of the customs lock can be located by the positioning module 305, and the position can be reported by the second radio frequency transceiver module 306. By adding a positioning module 305 in the lock body 3 of the customs lock, the entire transportation process can be monitored and tracked, the transportation safety and reliability of the customs lock can be improved, and the efficiency of retrieving goods can be improved.

[0029] Furthermore, in order to improve the communication flexibility of the customs lock and enable the customs lock to report abnormal situations in time when it is damaged, a communication function of a special frequency band can be added to the customs lock. In one embodiment, the lock body 3 also includes a wireless communication module, which is used to send the status and tag information of the customs lock to the cloud server; the wireless communication module is connected to the baseband chip 301. Specifically, the wireless communication module can be a 433 module, that is, a 433MHz wireless module, which performs wireless communication in the 433MHz frequency band and is widely used in the fields of Internet of Things, wireless data transmission, remote control, etc. Compared with other wireless communication modules, the 433 module is more suitable for projects with limited budgets and can reduce the cost of wireless communication; and the 433MHz frequency band belongs to the frequency band that is free of license use, which reduces the regulatory cost. In addition, the 433MHz signal is superior in penetrating walls and obstacles, and can provide a wider coverage range, so that wireless communication can be carried out in time when the customs lock is abnormal. In addition, modules of frequency bands such as 868 and 915 can also be selected for wireless communication, or wireless communication can be achieved through modules such as SIM card modules to help retrieve goods.

[0030] If the goods arrive at the designated customs safely and there is no abnormality, when the customs scans the RFID tag 102, an instruction to release the safe arrival supervision status can be sent to the lock body 3 through the cloud server. When the customs lock receives the instruction, the MCU controls the buckle structure 101 to retract and automatically unlock the customs lock.

[0031] In an embodiment of the present invention, the customs lock includes a lock cap 1 and a lock body 3 connected by a metal lock core 2, and the lock cap 1 includes a buckle structure 101 and a radio frequency tag 102 for controlling the opening and closing of the customs lock. When the buckle structure 101 is closed, the tag information of the radio frequency tag 102 can be transmitted through the metal lock core 2 to the first radio frequency transceiver module 302 connected to the baseband chip 301 in the lock body 3, so that the closing status of the customs lock can be judged by whether the lock body 3 can detect the tag information of the radio frequency tag 102. When the radio frequency tag 102 information of the customs lock cannot be scanned, it can be judged that there is a risk of the goods, so that the abnormal situation of the customs lock can be detected in time, thereby improving the safety of the customs lock.

[0032] It is worth mentioning that all modules involved in this embodiment are logic modules. In practical applications, a logic unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units. In addition, in order to highlight the innovative part of the present invention, this embodiment does not introduce units that are not closely related to solving the technical problem proposed by the present invention, but this does not mean that there are no other units in this embodiment.
