DETAILED DESCRIPTION

[0027] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figure 1-Figure 4 A multifunctional vertical light box for a park is shown, comprising a light box body 001 and an expansion detection mechanism, the expansion detection mechanism comprising a drive motor 201 and an expansion detection cover 202 matching the light box body 001, the drive motor 201 is fixedly installed on the top of the light box body 001, the expansion detection cover 202 is made of opaque material and is located on the left or right side of the light box body 001, an L-shaped linkage plate 203 is fixedly installed on the output end of the drive motor 201, a drive electric push rod 204 is fixedly installed on the linkage plate 203, the output end of the drive electric push rod 204 is fixedly connected to the expansion detection cover 202, and the expansion detection cover 202 is close to the light box body 001. One end of the box body 001 is set to an open shape, and a brightness sensor 205 is set on the inner side of the expansion detection cover 202. In the present embodiment, the brightness sensor 205 is directly fixedly mounted on the inner wall of the expansion detection cover 202, and the expansion detection mechanism also includes a detection intelligent controller 003 fixedly mounted on the linkage plate 203. The detection intelligent controller 003 is provided with a detection setting module, an analysis control module and a remote reminder module based on Internet technology. The detection setting module is signal-connected to the analysis control module, and the analysis control module is signal-connected to the driving motor 201, the driving electric push rod 204, the brightness sensor 205, and the remote reminder module.

[0030] A brightness threshold and a detection time node are reasonably set through the detection setting module (the time node with less traffic can be selected as the detection time node according to the work and rest time of the personnel in the park). The analysis and control module can control the detection regularly every day according to the set detection time node (multiple detection time nodes can also be set, so that the analysis and control module will control the drive motor 201 and other devices for detection multiple times a day). During the detection, the detection setting module will first control the drive motor 201 to drive the linkage plate 203 to rotate and adjust, so that the expansion detection cover 202 rotates to the main part of the light box The detection setting module will then control the electric push rod 204 to push the expansion detection cover 202 until the expansion detection cover 202 is tightly fitted with the light box body 001 (after the expansion detection cover 202 is fitted with the light box body 001, it can play a shading and sealing role to eliminate the interference of the ambient brightness on the detection). Then the detection setting module will start the brightness sensor 205 to perform brightness detection. The brightness data detected by the brightness sensor 205 will be fed back to the analysis control module, so that the analysis control module can judge by comparing the brightness data detected by the brightness sensor 205. Whether the light box body 001 is damaged, when the brightness data is lower than the brightness threshold, it means that the light box body 001 is damaged. At this time, the analysis and control module will control the remote reminder module to send reminder information to relevant technical personnel (the remote reminder module can send reminder information to relevant technical personnel remotely through the Internet, which is a prior art and will not be described here), so that relevant personnel can come for maintenance in time. After the detection is completed, the analysis and control module will turn off the brightness sensor 205 and control the electric push rod 204 to pull the expansion detection cover 202 and control the rotation motor 201 to drive it to rotate in the opposite direction ( The reverse direction here refers to the rotation direction when the front drive motor 201 drives the linkage plate 203 to rotate and adjust) to reset the expansion detection cover 202. Therefore, through the setting of the expansion detection mechanism, the expansion detection mechanism can automatically detect the light box main body 001 and determine whether the light box main body 001 is damaged. When the detection finds that the light box main body 001 is damaged, it will remotely remind the relevant technical personnel, which not only saves time and effort, but also enables the relevant technical personnel to discover the damage of the light box in time, so that the light box can be maintained in time, which greatly improves the functionality and intelligence of the light box.

[0031] See also Figure 2The end of the expansion detection cover 202 away from the light box main body 001 is detachably fixedly connected with a matching protective cover 206, and the end of the protective cover 206 close to the expansion detection cover 202 is set to an open shape. The protective cover 206 is made of transparent material. The expansion detection cover 202 can not only provide shading and sealing effects during detection, but also can be used to post park maps, posters, advertisements, etc. (maps can also be drawn directly on the expansion detection cover 202), and the protective cover 206 is used to provide sealing protection for maps, posters, etc., so that the light box can display more information, which not only improves the practicability of the expansion detection mechanism, but also further improves the functionality of the light box.

[0032] See also Figure 2 and Figure 3 A humidity sensor 207 fixedly mounted on the extended detection cover 202 is provided on the inner side of the protective cover 206. The humidity sensor 207 is connected to the analysis and control module signal. The humidity sensor 207 is used to monitor the humidity inside the protective cover 206, and the monitored humidity data will be transmitted to the analysis and control module. The relevant technical personnel can reasonably set a humidity threshold through the detection setting module. When the humidity data monitored by the humidity sensor 207 is greater than the humidity threshold, it means that there may be a problem with the sealing protection of the protective cover 206. At this time, the analysis and control module will control the analysis and control module to remotely send a reminder message to the relevant technical personnel, prompting the relevant technical personnel to come for maintenance in time to prevent the park map or posters on the inside of the humidity sensor 207 from being damaged, thereby further improving the functionality and intelligence of the light box.

[0033] The second implementation method:

[0034] Figure 5-Figure 8 A multifunctional vertical campus light box is shown. Different from the first embodiment, the expansion detection mechanism also includes a dustproof auxiliary detection component, which includes an electric push rod 401 fixedly installed on the inner wall of the expansion detection cover 202, and the output end of the electric push rod 401 is fixedly connected to a linkage rod 402, and the outer cover of the brightness sensor 205 is provided with a dust cover 403, and the outer wall of the dust cover 403 away from the side of the electric push rod 401 is provided with an entry and exit hole, and a sealing block 404 slidingly sealed and connected to the dust cover 403 is provided at the entry and exit hole, the dust cover 403 is fixedly connected to the expansion detection cover 202, the linkage rod 402 penetrates the outer wall of the dust cover 403 and is slidingly sealed therewith, and the end of the linkage rod 402 away from the electric push rod 401 is fixedly connected to the brightness sensor 205, the brightness sensor 205 is fixedly connected to the sealing block 404, and the analysis control module is connected to the signal of the electric push rod 401.

[0035] In the park, some green plants are usually planted, and leaves, dust and other debris are easy to adhere to the brightness sensor 205, affecting the accuracy of the brightness sensor 205, and then affecting the accuracy of the detection. To avoid this phenomenon, in the present embodiment, the brightness sensor 205 is arranged on the inner side of the dust cover 403, and the brightness sensor 205 is movably connected with the expansion detection cover 202 and the dust cover 403. The dust cover 403 can play a sealing and protective role for the brightness sensor 205. When the analysis and control module controls the driving motor 201 to perform detection, the detection setting module controls the driving electric push rod 204 to push the expansion detection cover 202 until the expansion detection cover 202 is tightly fitted with the light box main body 001. Before starting the brightness sensor 205, the electric push rod 401 will be controlled to push the brightness sensor 205 and the sealing block 404 to the dust cover through the linkage rod 402. The analysis and control module will start the brightness sensor 205 and the sealing block 404 before controlling the electric push rod 204 to pull the expansion detection cover 202, so as to reset the brightness sensor 205 and the sealing block 404. Therefore, through the setting of the dustproof auxiliary detection component, the dustproof auxiliary detection component can play a sealing and protective role on the brightness sensor 205 without affecting the detection, which can not only extend the service life of the brightness sensor 205, but also prevent leaves, dust and other debris from adhering to the brightness sensor 205 and affecting the accuracy of the brightness sensor 205, thereby improving the accuracy of the detection.

[0036] See also Figure 5-Figure 8The expansion detection mechanism also includes a joint damage detection component, which includes an air guide sealing cylinder 501 fixedly installed in the expansion detection cover 202, the air guide sealing cylinder 501 is located between the driving electric push rod 401 and the dust cover 403, the end of the air guide sealing cylinder 501 close to the dust cover 403 is set to an opening shape, and a piston plate 502 is provided in the air guide sealing cylinder 501 that is slidably sealed and connected thereto, and an end of the air outlet pipe 503 close to the driving electric push rod 401 is connected to the air outlet pipe 503 and the air intake pipe 504, and an air outlet one-way valve 505 is provided at the end of the air outlet pipe 503 away from the air guide sealing cylinder 501, and an end of the air intake pipe 504 away from the air guide sealing cylinder 501 passes through the expansion detection cover 2 02 and extends to the outside of the extended detection cover 202, and an intake one-way valve 506 is provided at one end of the intake pipe 504 away from the air-conducting sealing tube 501, the linkage rod 402 penetrates the air-conducting sealing tube 501 and is slidingly and sealingly connected to the outer wall of the air-conducting sealing tube 501, the linkage rod 402 penetrates the piston plate 502 and is fixedly connected to the piston plate 502, the combined damage detection component also includes an air pressure sensor 507 fixedly installed on the inner wall of the extended detection cover 202, and a damage detection module is also provided in the detection intelligent controller 003, the detection setting module and the analysis and control module are all connected to the damage detection module signal, and the damage detection module is signal-connected to the air pressure sensor 507 and the drive-out electric push rod 401.

[0037] The transparent panel on the light box is one of the important parts of the light box. With the use of the light box, the panel is easily damaged due to external force and other reasons, and corresponding maintenance needs to be carried out in time. In the present embodiment, during the process of detecting whether the light box body 001 is damaged, the analysis and control module controls the electric push rod 401 to push the brightness sensor 205 and the sealing block 404 to move outward from the dust cover 403 through the linkage rod 402. The movement of the linkage rod 402 will also drive the piston plate 502 to move together. The movement of the piston plate 502 will generate suction, so that a certain amount of air can be sucked into the air guide sealing cylinder 501 from the expanded detection cover 202 through the suction pipe 504 and the suction one-way valve 506, and the analysis and control module controls the electric push rod 401 to pull the brightness sensor 205 and sealing block 404, when the brightness sensor 205 and sealing block 404 are reset, the piston plate 502 will also be reset accordingly. During the resetting process of the piston plate 502, the air just inhaled will be discharged to the inner side of the expansion detection cover 202 through the air outlet pipe 503 and the air intake pipe 504, so that the air pressure inside the expansion detection cover 202 (that is, the area between the expansion detection cover 202 and the light box body 001) increases. A number parameter is reasonably set through the detection setting module. After the analysis and control module controls the electric push rod 401 to pull the brightness sensor 205 to reset the brightness sensor 205, a signal will be sent to the damage detection module. After receiving the signal, the damage detection module will control the electric push rod 401 to be driven out with the set number parameter. The movable linkage rod 402 moves back and forth several times, so that a large amount of air can be sucked and discharged to the inner side of the expansion detection cover 202, so that the air pressure inside the expansion detection cover 202 is significantly increased, and then the damage detection module will start the air pressure sensor 507, so that the air pressure sensor 507 monitors the air pressure inside the expansion detection cover 202, and the air pressure data monitored by the air pressure sensor 507 will be transmitted to the damage detection module. If the transparent panel on the light box body 001 is damaged, then the air will leak from the damaged part, causing the air pressure inside the expansion detection cover 202 to gradually decrease. On the contrary, if the transparent panel is not damaged, the air will not leak, and the air pressure inside the expansion detection cover 202 will be in a relatively stable state, so that the damage detection module can analyze the air pressure monitored by the air pressure sensor 507. The air pressure data received can be used to determine whether the transparent panel is damaged. The damage detection module will feed back the judgment result to the analysis and control module. If the judgment result is that the transparent panel is damaged, the analysis and control module will control the remote reminder module to send corresponding reminders to the relevant technical personnel, prompting the technical personnel to come and perform corresponding maintenance in time. In addition, after judging the result, the damage detection module will turn off the air pressure sensor 507, and the analysis and control module will control the electric push rod 204 and the motor 201 to reset the expansion detection cover 202 only after receiving the judgment result of the damage detection module. Therefore, through the setting of the combined damage detection component, the expansion detection mechanism also has the function of detecting whether the transparent panel on the light box main body 001 is damaged, and when the transparent panel is found to be damaged,It will also remotely send reminders to relevant technicians, further improving the functionality and intelligence of the light box.

[0038] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
