[0024] A security early warning method based on weight analysis and monitoring comprises the following steps:

[0025] S1. When monitoring the weight and image of employees, the employee passes through the security gate from the weight scale on one side. The employee is first weighed by the first weight scale. When weighing, the employee's face is recognized by the face recognition terminal, and the image of the employee is collected by the image acquisition module. Then, the employee's image is processed and stored by the image processing module. When the weight and appearance of the employee change, the image analysis module is used for analysis and comparison. When there is a big difference in the image, the early warning module can be used to cooperate with the security gate to issue an early warning. Then, the weight scale can be used to weigh the employee to collect the weight change of the employee. After the employee passes through the security gate, he will step on another weight scale and face recognition terminal. The weight change of the employee can be archived by another weight scale and face recognition terminal, and then the information is sent to the external mobile terminal through the controller;

[0026] S2. When the position of the face recognition terminal needs to be adjusted, the output end of the first motor is started to rotate, and the output end of the first motor is used to drive the screw rod to rotate, and the screw rod is moved on the surface of the screw rod by the rotation of the screw rod, and the movement of the screw rod drives the crossbeam to move, and the movement of the crossbeam drives the two face recognition terminals to move, so as to adjust the upper and lower positions of the two face recognition terminals; then the extension end of the cylinder is started to extend, and the extension end of the cylinder is used to push the mounting seat to move, and the movement of the mounting seat drives the face recognition terminal to move, so as to adjust the left and right positions of the face recognition terminal; the output end of the second motor is started to rotate, and the output end of the second motor is used to drive one of the pulleys to rotate, and then the rotating rod is driven to rotate through the transmission cooperation of the pulley and the transmission belt, and the fixed seat is driven to rotate by the rotation of the rotating rod, and the mounting frame and the face recognition terminal are driven to rotate by the rotation of the fixed seat, so as to adjust the angle of the face recognition terminal;

[0027] S3. When the face recognition terminal needs to be replaced, hold the handle and pull it upward. The movement of the handle pulls the connecting rope upward, and the movement of the connecting rope drives the two plug rods to move inward at the same time. The movement of the plug rod releases the spring, and when the plug rod is detached from the socket, the installation box can be disassembled. At this time, the face recognition terminal can be disassembled to facilitate the replacement and maintenance of the face recognition terminal.

[0028] Beneficial Effects

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] (1) In this solution, the output end of the first motor is started to rotate, and the rotation of the output end of the first motor drives the screw rod to rotate. The rotation of the screw rod causes the nut to move on the surface of the screw rod, and the movement of the nut drives the crossbeam to move. The movement of the crossbeam drives the two face recognition terminals to move, thereby adjusting the upper and lower positions of the two face recognition terminals.

[0031] (2) In this solution, the extension end of the cylinder is started to extend, and the extension of the extension end of the cylinder pushes the mounting seat to move, and the movement of the mounting seat pushes the face recognition terminal to move, thereby adjusting the left and right position of the face recognition terminal.

[0032] (3) In this solution, the output end of the second motor is started to rotate, and the output end of the second motor drives one of the pulleys to rotate, and then the transmission cooperation between the pulley and the transmission belt drives the rotating rod to rotate, and the rotation of the rotating rod drives the fixed base to rotate, and the rotation of the fixed base drives the mounting frame and the face recognition terminal to rotate, thereby adjusting the angle of the face recognition terminal.

[0033] (4) In this solution, when the face recognition terminal needs to be replaced, the handle is held and pulled upward. The movement of the handle pulls the connecting rope upward, and the movement of the connecting rope drives the two plug rods to move inward at the same time. The movement of the plug rods releases the spring. When the plug rods are detached from the sockets, the installation box can be removed. At this time, the face recognition terminal can be removed, thereby facilitating the replacement and maintenance of the face recognition terminal.

[0034] (5) In this scheme, when monitoring the weight and image of employees, the employee passes through the security gate from the weight scale on one side. The employee is first weighed on the first weight scale. When weighing, the employee's face is recognized through the face recognition terminal. The image of the employee is captured through the image acquisition module and then processed and stored through the image processing module. When the weight and appearance of the employee change, the image analysis module analyzes and compares the image. When there is a large difference in the image, the early warning module can be used in conjunction with the security gate to issue an early warning. Then, the weighing of the weight scale can collect the changes in the employee's appearance and weight. After the employee passes through the security gate, he will step on another weight scale and face recognition terminal. The changes in the employee's appearance and weight can be archived through another weight scale and face recognition terminal, and then the information can be sent to an external mobile terminal through the controller.

10. A security warning method based on weight analysis and monitoring, characterized in that: The security warning system based on weight analysis and monitoring as described in claim 9 is used, comprising the following steps: S1. When monitoring the weight and image of an employee, the employee passes through the security gate (1) from a weight scale (4) on one side. The employee is first weighed by the first weight scale (4). When weighing, the employee's face is recognized by the face recognition terminal (21). The image of the employee is captured by the image acquisition module and then processed and stored by the image processing module. When the weight and appearance of the employee change, the image analysis module is used to analyze and compare. When there is a large difference in the image, the early warning module can be used in conjunction with the security gate (1) to issue an early warning. Then, the weight scale (4) can be used to weigh the employee to collect the changes in the appearance and weight of the employee. After the employee passes through the security gate (1), he or she will step on another weight scale (4) and the face recognition terminal (21). The changes in the appearance and weight of the employee can be archived by another weight scale (4) and the face recognition terminal (21). Then, the controller (31) can send the information to an external mobile terminal. S2. When the position of the face recognition terminal (21) needs to be adjusted, the output end of the first motor (8) is started to rotate, and the screw rod (6) is driven to rotate by the rotation of the output end of the first motor (8), and the nut (7) is moved on the surface of the screw rod (6) by the rotation of the screw rod (6), and the cross beam (9) is driven to move by the movement of the nut (7), and the two face recognition terminals (21) are driven to move by the movement of the cross beam (9), so as to adjust the upper and lower positions of the two face recognition terminals (21); then, the extension end of the cylinder (12) is started to extend, and the extension end of the cylinder (12) is pushed to move the mounting seat (13), and the extension end of the cylinder (12) is pushed to move. The facial recognition terminal (21) is pushed to move by the movement of the mounting seat (13), thereby adjusting the left and right position of the facial recognition terminal (21); the output end of the second motor (17) is started to rotate, and one of the pulleys (18) is driven to rotate by the rotation of the output end of the second motor (17), and then the rotating rod (14) is driven to rotate by the transmission cooperation between the pulley (18) and the transmission belt (19), and the fixed seat (15) is driven to rotate by the rotation of the rotating rod (14), and the mounting frame (20) and the facial recognition terminal (21) are driven to rotate by the rotation of the fixed seat (15), thereby adjusting the angle of the facial recognition terminal (21); S3.
