After the upper end bent portion of the hook plate 12 is inserted into the fixing groove 42, the upper end bent portion of the hook plate 12 presses and pulls the third rope 41; after the third pull rope 41 is pulled, the elastic piece 412 is bent, and the bending direction faces the bottom surface of the indication slot 411;

when the mounting plate 2 is completely mounted in the fixing box 1, the upper end bending part of the hook plate 12 is inserted into the fixing groove 42, at this time, the upper end bending part of the hook plate 12 contacts and presses the stay cord III 41, so that the stay cord III 41 is pulled, one end of the stay cord III 41 far away from the fixing groove 42 is fixedly connected to the elastic piece 412, therefore, after the stay cord III 41 is pulled, the elastic piece 412 is bent, so that a worker can clearly and definitely judge the mounting state of the mounting plate 2 through observing the shape of the elastic piece 412 in the mounting process, the situation that the worker misjudges when the mounting plate 2 is not completely mounted in a preset position is avoided, the mounting of the mounting plate 2 is stopped, the mounting plate 2 is incompletely mounted in the fixing box 1, the upper end bending part of the hook plate 12 is separated from the fixing groove 42 after the monitoring equipment is subjected to external impact or vibration in the use process, the fixing of the fixing post 4 is relieved, the monitoring equipment is caused to drop and damage, and the normal work of the security monitoring system is influenced.

The specific working procedure is as follows:

when the security system works normally, video shot by a camera 3 in the monitoring equipment is uploaded to a server through a 5G network, then an analysis module at the server analyzes the received video, and separates personnel in the video from the environment, so that personnel identity and environmental safety are respectively analyzed, and meanwhile, after the analysis module confirms the personnel identity entering a monitoring area, after the identity information appears in the monitoring area as personnel stored in a database, the analysis module gives an alarm to a manager to remind the manager to process the personnel before; meanwhile, in the use process, the influence of personnel on the judgment of the security monitoring system is reduced by separating and independently analyzing the environment in the monitoring video; after the camera 3 and the mounting plate 2 are fixed through bolts, the mounting plate 2 is mounted in the fixed box 1 fixed on the wall, in the process of fixedly mounting the mounting plate 2 in the fixed box 1, the fixed column 4 on the mounting plate 2 gradually enters the fixed box 1, after the mounting plate 2 completely enters the fixed box 1, one end of the fixed column 4 positioned in the fixed box 1 contacts and presses the first pull rope 121, so that the first pull rope 121 is pulled under the action of the fixed column 4, and as the two ends of the first pull rope 121 are respectively fixedly connected to the inner wall of the fixed box 1 and the hook plate 12, and meanwhile, the hook plate 12 is hinged to the connecting plate 11, after the first pull rope 121 is contacted and pressed by the fixed column 4, the hook plate 12 rotates in the direction of the fixed column 4 under the action of the first pull rope 121, and then the bent part of the upper end of the hook plate 12 is inserted into the fixed groove 42 on the fixed column 4, so that the fixing of the fixed column 4 is completed; meanwhile, since the hook plate 12 has magnetism and the fixing post 4 is made of a soft magnetic material, after the upper end bent portion of the hook plate 12 is inserted into the fixing groove 42 on the fixing post 4, the upper end bent portion of the hook plate 12 is adsorbed and fixed in the fixing groove 42 by a magnetic force; meanwhile, when the monitoring equipment is required to be disassembled and maintained or replaced, a worker adsorbs a strong magnet to the end face of the fixed column 4, which is positioned on the surface of the mounting plate 2, the fixed column 4 is magnetized by the magnetic field of the strong magnet, the fixed column 4 forms a magnetic field with the same direction as the magnetic field of the hook plate 12, and then the bent part at the upper end of the hook plate 12 is pulled out of the fixed groove 42 under the repulsive force between the magnetic fields, so that the fixation of the fixed column 4 is released; after the mounting plate 2 is completely mounted in the fixing case 1, the upper end bent portion of the hook plate 12 is inserted into the fixing groove 42, and at this time, the upper end bent portion of the hook plate 12 contacts and presses the third rope 41, so that the third rope 41 is pulled, and since one end of the third rope 41 away from the fixing groove 42 is fixedly attached to the elastic piece 412, the elastic piece 412 is bent after the third rope 41 is pulled; after the mounting plate 2 is completely mounted in the fixing case 1, the upper bent portion of the hook plate 12 is inserted into the fixing groove 42 on the fixing post 4, the fixing post 4 is magnetized by the magnetic field of the hook plate 12, so that the fixing post 4 forms a magnetic field having the same direction as the magnetic field of the hook plate 12, and meanwhile, since the magnetic field of the hook plate 12 is the same as the magnetic field of the protruding block 221, a magnetic force which repels each other exists between the protruding block 221 and the fixing post 4, so that the protruding block 221 moves towards the outside of the protruding hole 22 under the action of the magnetic field, and finally the protruding block 221 protrudes out of the protruding hole 22 and the portion of the protruding block 221 located outside of the protruding hole 22 is inserted into the fixing hole 14; meanwhile, when the monitoring equipment needs to be disassembled, and the monitoring equipment is replaced or maintained, a worker uses a strong magnet with a specific shape to disassemble, meanwhile, in the disassembly process, the strong magnet with the specific shape is inserted into the extrusion hole 43, and meanwhile, the magnetic field intensity of the strong magnet with the specific shape used in the disassembly is larger than that of the hook plate 12, so that after the strong magnet with the specific shape is inserted into the extrusion hole 43, the strong magnet magnetizes the fixing column 4; meanwhile, since the second pulling rope 222 connecting the bottom surface of the transverse hole 44 and the protruding block 221 passes through the extrusion hole 43, after the strong magnet of a specific shape is inserted into the extrusion hole 43, the strong magnet contacts and extrudes the second pulling rope 222, thereby pulling the second pulling rope 222 to drive the protruding block 221 to move toward the fixed column 4, and when the protruding block 221 moves to one end of the protruding hole 22 near the fixed column 4, the protruding block 221 is subjected to the magnetic attraction force of the fixed column 4 magnetized by the strong magnet, so that the position of the protruding block 221 in the protruding hole 22 is kept relatively fixed, and the locking of the protruding block 221 to the mounting plate 2 is released; meanwhile, since the magnitude of the magnetic force between the protruding block 221 and the fixing post 4 is negligible after the protruding block 221 is inserted into the fixing hole 14, the protruding block 221 does not move toward the fixing post 4 before the strong magnet of a specific shape is inserted into the pressing hole 43 in the use process, thereby contacting the fixing of the mounting plate 2; after the mounting plate 2 is completely mounted in the fixed box 1, the locking column 21 is inserted into the locking cylinder 13, meanwhile, the hook plate 12 is not contacted with the locking cylinder 13 any more because the hook plate 12 rotates under the action of the first pulling rope 121, and meanwhile, after the hook plate 12 is separated from the locking cylinder 13, the movable plate 134 moves towards the direction of the locking column 21 under the action of the spring 135, so that the first friction wheel 136 is contacted with the second friction wheel 137 and is pressed on the surface of the locking column 21; meanwhile, when the locking column 21 moves in the vertical direction, the locking column 21 has a trend of moving in the vertical direction, and because the friction wheel I136 and the friction wheel II 137 are in contact with the locking column 21, a rotating movement trend also exists under the action of the movement trend of the locking column 21, and meanwhile, because the friction wheel I136 and the friction wheel II 137 are in contact with each other, the rotation directions of the friction wheel I136 and the friction wheel II 137 are opposite, and the two directions are offset, so that the movement trends of the friction wheel I136, the friction wheel II 137 and the locking column 21 which are in contact with each other are mutually blocked, and the relative position of the locking column 21 is fixed; by the first friction groove 138 and the second friction groove 211, the friction force between the first friction wheel 136 and the second friction wheel 137, the friction force between the first friction wheel 136 and the locking column 21 and the friction force between the second friction wheel 137 and the locking column 21 can be increased, and the possibility of sliding of the mounting plate 2 under the action of external force can be reduced.
