BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0013] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of the present invention is not limited to the following embodiments, and any form of modification and / or change made to the present invention will fall within the protection scope of the present invention.

[0014] like Figure 1 As shown, the present invention discloses a technical solution, an intelligent flexible lock control system, comprising: The electronic seal and control circuit, the motor and the motor driving circuit are used to realize the sealing and unsealing functions of the electronic seal. Through the motor and the motor driving circuit, the sealing and unsealing operations of the electronic seal can be accurately controlled, providing a basic guarantee for the safety protection of the articles. The motor and the motor driving circuit can adopt the existing technology, and the specific structure and principle thereof can be derived by those skilled in the art through conventional means, which will not be repeated here.

[0015] The 4G communication module communicates with the remote IoT platform via TCPIP to achieve remote control of the electronic seal and real-time status reporting. Through this module, managers can remotely control the electronic seal and obtain the status information of the electronic seal in real time, which greatly improves the convenience and timeliness of management.

[0016] The positioning module uses a Beidou / GPS dual-mode positioning chip and is connected to the 4G communication module through an I2C interface to collect the geographical location of the electronic seal. The dual-mode positioning chip can improve the accuracy and reliability of positioning, ensure that the location information of the electronic seal can be accurately obtained, and provide strong support for the tracking and supervision of items.

[0017] The LoRa communication module realizes the short-range communication function and cooperates with the short-range LoRa host to realize the short-range control and real-time status collection of the electronic seal. Within the short-range range, the module can communicate efficiently with the LoRa host, which is convenient for on-site personnel to control and collect the status of the electronic seal, increasing the flexibility of operation.

[0018] The main control Bluetooth module realizes the short-range Bluetooth communication function, and cooperates with the mobile phone APP to realize the Bluetooth control and real-time status collection of the electronic seal. At the same time, the main control Bluetooth module is connected to the 4G communication module and the LoRa module through the SPI bus to realize data interaction and collaborative work between the modules; through the mobile phone APP, the operator can easily control and query the status of the electronic seal on site, which improves work efficiency.

[0019] RFID encrypted information tags use a timestamp synchronization encryption algorithm to update the authentication key every 60 seconds to achieve the anti-counterfeiting function of electronic seals. This encryption method can effectively prevent electronic seals from being illegally counterfeited, improving the security and reliability of the seals.

[0020] The battery and charging circuit provide power for the entire system to ensure that all parts of the system can work normally. At the same time, the charging circuit can charge the battery to ensure the battery's endurance and meet the system's long-term operation requirements; the battery and charging circuit can adopt existing technology, and the specific structure and principle can be obtained by those skilled in the art through conventional means, which will not be repeated here.

[0021] The storage module is used to store the offline data of the electronic seal, as well as the sealing and unsealing status, geographic location information, etc. Even when the system is offline, it can reliably record the relevant data, and after the communication is restored, the stored data can be uploaded to the remote IoT platform to ensure the integrity and continuity of the data.

[0022] The status indicator light circuit is used to indicate the system status. Through different light states, the operator can intuitively understand the working status of the system, which is convenient for troubleshooting and maintenance.

[0023] The application provides an intelligent flexible lock control system, the use process is as follows: 1. System Installation On the items that need to use the intelligent flexible locking system, choose a suitable location to install the electronic seal and control circuit; reliably connect the electronic seal to the lock structure of the item to ensure effective sealing and unsealing operations, connect the battery and charging circuit to provide power to the system, and ensure that the charging circuit can work normally so as to charge the battery.

[0024] According to the system connection requirements, correctly connect the 4G communication module, positioning module, LoRa communication module, main control Bluetooth module, RFID encryption information tag, storage module and status indicator circuit to ensure the stability of the communication interface between the modules. For example, the positioning module is connected to the 4G communication module through the I2C interface, and the main control Bluetooth module is connected to the 4G communication module and the LoRa module respectively through the SPI bus.

[0025] 2. System initialization Initialize the installed intelligent flexible lock control system. After starting the system, first configure the 4G communication module so that it can connect to the designated remote IoT platform through TCPIP, and configure the positioning module so that it can normally receive Beidou and GPS satellite signals to achieve accurate geographic location positioning.

[0026] Initialize the LoRa communication module and the main control Bluetooth module so that they can work normally and communicate with the corresponding devices; at the same time, initialize the RFID encryption information tag and set the relevant parameters of the timestamp synchronization encryption algorithm to ensure that the authentication key can be updated normally every 60 seconds.

[0027] 3. Sealing operation When it is necessary to seal the items, the operator can use the mobile phone APP to communicate with the intelligent flexible lock control system through the main control Bluetooth module, select the sealing operation on the mobile phone APP, and send the sealing instruction. After the main control Bluetooth module receives the instruction, it transmits the instruction to the electronic seal and the motor drive circuit in the control circuit through the SPI bus.

[0028] The motor drive circuit drives the motor to work and realize the sealing function of the electronic lead seal. During the sealing process, the positioning module collects the current geographical location information in real time, and the storage module records the sealing status and geographical location information; at the same time, the 4G communication module reports the sealing information to the remote Internet of Things platform in real time, and the manager can understand the sealing situation in real time through the Internet of Things platform.

[0029] 4. Goods transportation and monitoring During the transportation of items, the 4G communication module continuously connects to the remote IoT platform via TCPIP and reports the status information of the electronic seal in real time. If the electronic seal is opened illegally, the system will immediately detect the status change and send an alarm message to the manager through the 4G communication module; at the same time, the positioning module records the geographic location information when it is opened, and reports this information together with the alarm information to the remote IoT platform.

[0030] Within a short distance, the short-range LoRa host can collect the status information of the electronic seal in real time through the LoRa communication module to realize multiple monitoring of the transportation process. The operator can also use the mobile phone APP to communicate with the intelligent flexible lock control system using the main control Bluetooth module to query the status information of the electronic seal in real time.

[0031] 5. Unblocking operation When the item arrives at the destination or needs to be unsealed, the operator also uses the mobile phone APP to send the unsealing instruction through the main control Bluetooth module. The main control Bluetooth module transmits the instruction to the motor drive circuit in the electronic seal and control circuit, drives the motor to work, and realizes the unsealing of the electronic seal.

[0032] During the unblocking process, the storage module records information such as the unblocking status and geographic location, and uploads this information to the remote IoT platform through the 4G communication module. Administrators can verify and manage the unblocking operation through the IoT platform to ensure the legality and security of the operation.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
