[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figure 1 , Figure 2 As shown, the exhibition hall status inspection system adopts a top-mounted structure to move and inspect according to the distribution of exhibits. The linear track 1 is fixed on the top of the exhibition hall according to the distribution of exhibits. The cross section of the linear track 1 is L-shaped, and the two sides of the vertical part of the linear track 1 are concave inward to form symmetrically distributed wheel grooves 11;

[0027] like Figure 2 , Figure 3As shown, the driving assembly includes two sets of aligned driving wheels 22 and driven wheels 23, the two driving wheels 22 are rotatably mounted on the surface of the packaging shell 2, and the two driven wheels 23 are rotatably mounted on the surface of the carrier 21, the driving wheels 22 and the driven wheels 23 are distributed on both sides of the linear rail 1 and are inserted into the wheel groove 11, and then the carrier 21 is fixedly connected with the packaging shell 2 by screws, so that the driving wheels 22 and the driven wheels 23 are stably clamped on the linear rail 1 to stably move and suspend the packaging shell 2, and the supporting wheels 24 are rotatably mounted on the surface of the packaging shell 2, and the supporting wheels 24 are against the surface of the linear rail 1 to increase the stability of the combination of the packaging shell 2 and the linear rail 1, and the motor 6 is installed in the packaging shell 2, and the driving wheel 22 is connected to the motor 6 by a transmission assembly;

[0028] The energy storage battery, controller, and wireless signal transceiver module are installed in the packaging shell 2, which are all prior arts and will not be described in detail here. They are mainly used for power supply, remote signal transmission, and working logic programming control of the device;

[0029] like Figure 3 , Figure 4 As shown, a rotating seat 4 is rotatably installed at the bottom of the packaging shell 2, and the monitoring device 3 adopts a monitoring camera, an infrared imager or other monitoring equipment, and is configured with a mature picture tracking control logic in the prior art. The monitoring device 3 is elastically rotated at the bottom of the rotating seat 4 through a torsion spring, so that the monitoring device 3 has a tendency to rotate upward, and the center position of the rotating seat 4 vertically slides through the resistance member 5, and the resistance member 5 maintains vertical sliding and lifting with the packaging shell 2 through a sliding structure, and the bottom of the resistance member 5 presses the upper surface of the monitoring device 3, and a cam 62 is rotatably installed in the packaging shell 2, and the cam 62 presses and contacts the top of the resistance member 5, and the output shaft of the motor 6 is synchronously driven to connect the rotating seat 4 and the reducer 61 through a bevel gear set, and the output shaft of the reducer 61 is connected to the cam 62;

[0030] The motor 6 is turned on to drive the driving wheel 22 to rotate. The driving wheel 22 and the driven wheel 23 are clamped and limited, so that the packaging shell 2 moves along the linear track 1. The motor 6 synchronously drives the rotating seat 4 to rotate, so that the monitoring device 3 rotates to monitor the status in the hall. At the same time, the motor 6 drives the cam 62 to rotate slowly. The cam 62 resists the resistance member 5 and moves up and down slowly, so that the resistance member 5 presses the monitoring device 3 to adjust the up and down angles during the rotation process, so that the monitoring device 3 can fully cover and monitor the status in the entire hall;

[0031] The rotation angular velocity ratio of the swivel seat 4 and the cam 62 is greater than 10:1, so that the cam 62 pushes the resistance member 5 to press down the monitoring device 3 at a slower speed, so that the upward and downward angle adjustment range of the monitoring device 3 is small each time it rotates around, which can ensure that the monitoring device 3 can achieve comprehensive angle adjustment monitoring in a continuous rotation state.

[0032] The fixed-point monitoring modes are as follows:

[0033] like Figure 4 , Figure 5As shown, the abutment 5 includes a plug barrel 51, a piston body 53 is adapted to slide inside the plug barrel 51, the piston body 53 and the upper part of the plug barrel 51 form a closed air cavity, a telescopic column 52 connected to the piston body 53 is slidably inserted into the bottom of the plug barrel 51, a micro air pump 7 is installed in the packaging shell 2, the micro air pump 7 is connected to the closed air cavity through a valve assembly 8, an air pressure sensor 9 is arranged in the closed air cavity, and the air pressure sensor 9 is connected to the micro air pump 7 through a controller;

[0034] like Figure 6 As shown, the transmission assembly includes a driving gear 64 arranged on the output shaft of the motor 6 and driven gears 63 symmetrically distributed on both sides of the driving gear 64, the driven gear 63 is connected to the driving wheel 22 by transmission, a guide frame 66 is vertically slidably installed in the packaging shell 2, two sets of linkage gears 65 are rotatably installed on the surface of the guide frame 66, the linkage gear 65 is aligned between the driving gear 64 and the driven gear 63, and a first electromagnetic telescopic rod 67 fixed to the packaging shell 2 is arranged on the top of the guide frame 66;

[0035] When the monitoring device 3 detects an abnormal state and needs fixed-point monitoring, the controller controls the first electromagnetic telescopic rod 67 to contract, so that the guide frame 66 drives the linkage gear 65 to move upward, disconnects the transmission connection between the driven gear 63 and the driving gear 64, and keeps the packaging shell 2 in a fixed position. At this time, the motor 6 can only drive the rotating seat 4 to rotate quickly and the cam 62 to rotate slowly, control the monitoring device 3 to rotate to the monitoring direction, and then turn on the micro air pump 7 to replenish or exhaust air in the closed air cavity, adjust the telescopic length of the telescopic column 52, and independently adjust the downward rotation angle of the monitoring device 3, so that the monitoring device 3 can be accurately fixed-point monitored;

[0036] When the monitoring mode is adjusted to the inspection state, the air pressure in the closed air cavity is monitored by the air pressure sensor 9, and the information is fed back to the controller. The controller controls the micro air pump 7 to introduce or extract gas into the closed air cavity to maintain a relatively constant air pressure in the closed air cavity. The extension length of the telescopic column 52 is relatively fixed, and the downward rotation angle of the monitoring device 3 cannot be independently controlled. The rotation of the monitoring device 3 is controlled by the motor 6 to be synchronized with the downward swing.

[0037] like Figure 7 As shown, the valve assembly 8 includes a valve body 81, one side of the valve body 81 is provided with a first port 83 and a second port 84 connected to the input and output ends of the micro air pump 7, and the other side of the valve body 81 is provided with a third port 85 connected to the closed air cavity, and the third port 85 is located between the first port 83 and the second port 84. Both ends of the valve body 81 are connected to the external environment, and two fixed valve plates 86 are adapted to be arranged in the valve body 81, and an independent isolation space is formed between the two valve plates 86. The second electromagnetic telescopic rod 82 is installed at one end of the valve body 81, and the valve plate 86 is connected to the second electromagnetic telescopic rod 82;

[0038] When supplying air to the closed air cavity, the second electromagnetic telescopic rod 82 is turned on to extend so that the valve plate 86 moves to the right, so that the independent isolation space connects the third port 85 with the second port 84, and the first port 83 is connected to the external environment from the left end of the valve body 81. The micro air pump 7 extracts external gas through the first port 83, and then introduces it into the closed air cavity through the second port 84, the independent isolation space, and the third port 85, so as to control the extension of the telescopic column 52;

[0039] When the closed air cavity is evacuated, the second electromagnetic telescopic rod 82 is turned on to shorten the valve plate 86 to move to the left, so that the independent isolation space connects the third port 85 with the first port 83, and the second port 84 is connected to the external environment from the right end of the valve body 81. The micro air pump 7 extracts the gas in the closed air cavity through the first port 83, the independent isolation space, and the third port 85, and then discharges it to the external environment through the second port 84, thereby controlling the telescopic column 52 to shorten.

[0040] A solenoid valve is provided between the third port 85 and the sealed air cavity, and is used to close the pipeline when the air pressure of the sealed air cavity is not adjusted, so as to maintain a constant air pressure in the sealed air cavity.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
