Description
Technical Field
[0001] This invention relates to the field of monitoring device technology, and in particular to a monitoring device for underground intelligent parking lots. Background Technology
[0002] With the advancement of smart city construction, underground parking lots are placing higher demands on the reliability, intelligence, and operational efficiency of video surveillance systems. Currently, underground parking lots commonly use fixed network cameras for 24-hour monitoring. These cameras are typically installed above the driveways or on pillars for vehicle identification, pedestrian behavior analysis, and security.
[0003] However, in actual operation, such systems have significant drawbacks. First, once a camera malfunctions (such as power outage, lens damage, or communication abnormalities), maintenance personnel must carry ladders to the site for repair or replacement, with an average repair time of several hours. During this time, blind spots are created, seriously affecting the effectiveness of security. Second, although some inspection robots or tracked vehicles have been used for garage environmental monitoring, their functions are limited to mobile shooting and lack mechanical coordination with the monitoring equipment itself, making it impossible to quickly plug and unplug faulty units. In addition, existing track systems mostly adopt rigid installation methods, without considering the impact of vehicle vibration on the stability of monitoring imaging. Furthermore, long-distance tracks are prone to deformation under thermal expansion and contraction or their own weight, affecting the smooth operation of the vehicle. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that it is inconvenient to inspect and replace cameras when they malfunction in the prior art, and to propose a monitoring device for underground intelligent parking lots.

The running track includes multiple spliced and fixedly mounted split tracks. Mounting components are fixedly mounted on both the upper and lower sides of each split track. The mounting components are fixedly connected to the support rod via the mounting component. A wiring component is fixedly mounted on the side of each split track closest to the support rod. The maintenance trolley includes a vehicle body, on which two wheels driven by a drive motor are rotatably connected. A centering limit component and a faulty equipment replacement mechanism are fixedly mounted on the vehicle body.
[0006] Preferably, the faulty equipment replacement mechanism includes a disassembly arm fixedly connected to the side of the vehicle body away from the support rod.

A torsion spring is fixedly connected between the clamping plate and the outer shell of each of the two damping shafts. A pressure plate is fixedly connected to the first connecting plate by a pressure spring. A clamping seat is fixedly mounted on the monitoring equipment. The clamping seat has a groove corresponding to the clamping plate. A loop hook is fixedly mounted on the clamping plate. A hook groove corresponding to the loop hook is opened on the inner side of the groove. A cleaning arm is fixedly mounted on the vehicle body. A second electric telescopic rod is fixedly mounted on the cleaning arm. A second connecting plate is fixedly mounted on the second electric telescopic rod. A monitoring camera is fixedly mounted on the disassembly arm by a fixing rod.
[0007] Preferably, a cleaning component is installed on the second connecting plate. The cleaning component includes a motor fixedly installed on the second connecting plate. The output end of the motor passes through the second connecting plate and is fixedly connected to the cleaning plate. Microfiber bristles are installed on the inner surface of the cleaning plate.
[0008] Preferably, the positioning component includes a positioning hole on the inner surface of the mounting groove, a positioning rod is slidably connected in the positioning hole, a return spring is fixedly connected between the positioning hole and the positioning rod, a limit groove is opened on the surface of the monitoring device, and one end of the positioning rod extending out of the positioning hole is set as a curved surface matching the limit groove.
[0009] Preferably, the mounting assembly includes two mounting rods fixedly connected to the support rod, and rubber sleeves are fixedly installed on the inner surfaces of the two mounting components. The two mounting rods are respectively inserted into the two rubber sleeves. A first baffle is fixedly connected to the mounting rod. A bolt is internally threaded to the end of the mounting rod away from the support rod. A second baffle is fixedly connected to the bolt.

It can use its onboard pan-tilt camera to provide close-up, multi-angle real-time images, which can make up for the limitations of fixed camera perspectives and improve the efficiency of incident handling. 3. The use of a modular track structure with installation components (such as U-shaped mounting blocks and elastic rubber pads) effectively isolates the transmission of trolley vibrations to the building structure, while allowing the track to expand and contract slightly with temperature changes, avoiding jamming or derailment caused by deformation.

[0016] See Figures 1-11 A monitoring device for an underground intelligent parking lot includes a bracket 1, a pluggable monitoring module 2, a running track 3, and a maintenance trolley 4. The bracket 1 includes a support rod 11, which is fixed to the ceiling of the parking lot by bolt assembly. A base plate 12 is fixedly connected to the bottom end of the support rod 11. The base plate 12 has an interconnected mounting groove 121 and a slot 122. The pluggable monitoring module 2 includes a monitoring device 21, on which a pluggable socket 22 is fixedly installed. The monitoring device 21 is plugged into the mounting groove 121, and the pluggable socket 22 is plugged into the slot 122. The slot 122 is equipped with power and signal line interfaces. The pluggable socket 22 is equipped with a corresponding plug-in connector. A positioning component is fixedly installed between the monitoring device 21 and the mounting groove 121.
[0017] like Figure 2 and Figure 6 As shown, the positioning assembly includes a positioning hole 123 on the inner surface of the mounting groove 121. A positioning rod 124 is slidably connected in the positioning hole 123. A return spring is fixedly connected between an inner surface of the positioning hole 123 and the end of the positioning rod 124 away from the monitoring device 21. A limit groove 26 is opened on the outer surface of the monitoring device 21. The end of the positioning rod 124 extending out of the positioning hole 123 is set with a curved surface that matches the limit groove 26.
[0018] Since the monitoring device 21 is inserted into the mounting slot 121 and the plug-in socket 22 is inserted into the slot 122, in order to ensure that the plug-in socket 22 can be quickly and accurately aligned and inserted into the slot 122 when installing the monitoring device 21, the present invention provides a positioning component. When installing the monitoring device 21, the limiting groove 26 first enters the mounting slot 121 with the monitoring device 21 and slowly rotates the monitoring device 21 around the center of the mounting slot 121 until the limiting groove 26 is aligned with the positioning hole 123. At this time, the positioning rod 124 will be pushed out under the elastic force of the return spring, and its curved end extends into the limiting groove 26 to prevent the monitoring device 21 from continuing to rotate. Next, the rotation of the monitoring device 21 is stopped. Since the limiting groove 26 is aligned with the positioning hole 123, the plug-in socket 22 is also aligned with the slot 122. The monitoring device 21 is then pressed down to insert the plug-in socket 22 into the slot 122. With the help of the positioning component, the installation accuracy and installation efficiency can be significantly improved.
[0019] like Figure 2 , Figure 6 , Figure 7 and Figure 11 As shown, the running track 3 includes multiple spliced and fixed split tracks 31. The running track 3 can be regarded as a single module, which can cover a part of the underground parking lot. The multi-module network can achieve full coverage of the underground parking lot. The upper and lower surfaces of the split track 31 are fixedly installed with mounting parts 32. The mounting parts 32 are fixedly connected to the support rod 11 through the mounting components.
[0020] The mounting assembly includes two mounting rods 13 fixedly connected to the support rod 11. Rubber sleeves 33 are fixedly installed on the inner surfaces of the two mounting parts 32. The two mounting rods 13 are respectively inserted into the two rubber sleeves 33. A first baffle 14 is fixedly connected to the mounting rod 13. A bolt 15 is internally threaded to the end of the mounting rod 13 away from the support rod 11. A second baffle 16 is fixedly connected to the bolt 15. Rubber gaskets 17 are fixedly installed on the side surfaces of the first baffle 14 and the second baffle 16 that are close to each other. A wiring assembly is fixedly installed on the side surface of the split track 31 that is close to the support rod 11. The wiring assembly includes two side plates 34 fixedly connected to the side surface of the split track 31 that is close to the support rod 11. A sealing strip 35 is inserted into each of the two side plates 34.
[0021] With the cooperation of the rubber sleeve 33 and rubber gasket 17 in the installation assembly, the minor vibrations generated when the maintenance trolley 4 moves within the running track 3 are buffered in multiple directions, thereby reducing the impact of the vibration on the support rod 11 and ensuring the stability of the monitoring screen when the monitoring equipment 21 installed in the slot 122 is working. In the wiring assembly, a space is formed between the split track 31, the side plate 34 and the sealing strip 35, which can be used for the wiring of the power lines and signal lines required for the power supply and signal transmission of the monitoring equipment 21. The sealing strip 35 is inserted into the side plate 34, which is easy to disassemble and facilitates the initial wiring layout and subsequent inspection and maintenance.
[0022] like Figure 9 and Figure 10 As shown, the maintenance vehicle 4 includes a vehicle body 41, on which two driving wheels 411 driven by a drive motor are rotatably connected. A centering limit component is fixedly installed on the vehicle body 41. The centering limit component includes multiple first rollers 412 and multiple second rollers 413. The multiple first rollers 412 are rotatably connected to both ends of the vehicle body 41, and the multiple second rollers 413 are rotatably connected to both sides of the vehicle body 41. The first rollers 412 and the second rollers 413 are in rolling contact with the inner surface of the split track 31. A faulty equipment replacement mechanism is fixedly installed on the vehicle body 41.
[0023] By using multiple first rollers 412 and second rollers 413, the vibration generated when the vehicle body 41 moves within the split track 31 can be reduced. The limiting effect ensures that the vehicle body 41 remains centered, avoiding significant shaking during movement and preventing the vehicle body 41 from shifting position, which would affect the subsequent disassembly and replacement of the fault monitoring equipment and cause misalignment between the fault equipment replacement mechanism and the monitoring equipment 21.
[0024] The faulty equipment replacement mechanism includes a disassembly arm 42 fixedly connected to the surface of the vehicle body 41 away from the support rod 11. A stepper motor 421 is fixedly mounted on the disassembly arm 42. The output end of the stepper motor 421 extends out of the disassembly arm 42 and a first electric telescopic rod 422 is fixedly mounted on it. A first connecting plate 423 is fixedly mounted on the output end of the first electric telescopic rod 422. Three sets of symmetrically arranged damping shafts 424 are fixedly connected to the bottom surface of the first connecting plate 423. Each set has two damping shafts 424. Clamping plates 425 are fixedly connected between the ends of the two damping shafts 424. Torsion springs 426 are fixedly connected between the two sides of the clamping plates 425 and the outer shells of the two damping shafts 424. The damping shafts 42 are existing technology. The damping effect of the damping shafts 42 is generated between the shaft ends and the outer shells. The function of the torsion springs 426 is to enable the clamping plates 425 to automatically return to their original position after rotation. The clamping plates 425 fixedly connected to the shaft ends can achieve a delayed return effect during the return process by means of the damping effect of the damping shafts 424. A pressure plate 427 is fixedly connected to the bottom surface of the first connecting plate 423 by a pressure spring. A clamping seat 23 is fixedly installed on the monitoring device 21. A groove 24 corresponding to the clamping plate 425 is opened on the clamping seat 23. A loop hook is fixedly installed on the bottom end of the clamping plate 425. A hook groove 25 corresponding to the loop hook is opened on the inner surface of the groove 24. A cleaning arm 43 is fixedly installed on the side surface of the vehicle body 41 away from the support rod 11. A second electric telescopic rod 431 is fixedly installed on the bottom surface of the cleaning arm 43. A second connecting plate 432 is fixedly installed on the output end of the second electric telescopic rod 431. A monitoring camera 428 is fixedly installed on the bottom side of the disassembly arm 42 by a fixing rod.
[0025] A wireless communication module is installed on the vehicle body 41. The wireless communication module can be a Wi-Fi, Bluetooth, 4G or 5G module, which is used to receive control commands from the monitoring center to realize remote manual operation. The control commands include movement, stop, lifting and rotating. A battery is installed inside the vehicle body 41, which allows the vehicle body 41 to work over long distances without a power cord. At one end of the entire track, a charging pile can be installed for the vehicle body 41 to automatically charge when it stops. At this end, two installation positions for monitoring equipment 21, similar to the base plate 12 and the mounting slot 121, are installed. One position is used to place a new monitoring equipment 21 for replacement, and the other position is used to place the old monitoring equipment 21 that has been disassembled due to failure.
[0026] When staff in the monitoring room discover a malfunction in a monitoring device 21 through the monitoring screen, they issue a command via the control panel. The wireless communication module transmits the command to the vehicle 41, controlling the vehicle 41 to move along the split track 31 to the location of the malfunctioning monitoring device 21. Upon reaching the malfunction point, they observe and record the external condition of the monitoring device 21 using the monitoring camera 428. If it is confirmed that the monitoring device 21 needs to be replaced, they control the second electric telescopic rod 431 to extend, causing the second connecting plate 432 to move down to the same height as the base plate 12. They then control the vehicle 41 to move away from the cleaning arm 43 until the second connecting plate... 432 is blocked by the base plate 12 and rests against the outer surface of the base plate 12. At this time, the first connecting plate 423 is aligned with the central axis of the monitoring device 21, controlling the extension of the first electric telescopic rod 422. The output end of the first electric telescopic rod 422 drives the clamping plate 425 to move downward through the first connecting plate 423 and the damping shaft 424. If the clamping plate 425 is not aligned with the groove 24 on the clamping seat 23, the stepper motor 421 is controlled to rotate. The output end of the stepper motor 421 drives the first electric telescopic rod 422, the first connecting plate 423 and the damping shaft 424 to rotate until the clamping plate 425 is aligned with the groove 24. If the alignment is complete, continue to extend the first electric telescopic rod 422 to slowly lower the clamping plate 425. The bottom end of the clamping plate 425 slides along the inner surface of the groove 24 until the loop hook at the bottom of the clamping plate 425 aligns with the hook groove 25. Under the elastic force of the torsion spring 426, the clamping plate 425 drives the loop hook into the hook groove 25. Then, control the first electric telescopic rod 422 to shorten, and the clamping plate 425 moves upward as the first electric telescopic rod 422 shortens, first engaging the loop hook in the hook groove 25 to achieve clamping of the clamping seat 2. The clamping mechanism 3 is used to move the clamping seat 23 and the monitoring device 21 upwards via the loop hook, pulling the monitoring device 21 upwards from the slot 122 to complete the disassembly of the faulty monitoring device 21. The second electric telescopic rod 431 is controlled to shorten, driving the second connecting plate 432 upwards. Then, the vehicle body 41 is controlled to move to the installation position at the end of the track, where the faulty monitoring device 21 is placed in, and the new monitoring device 21 is taken out and clamped between multiple clamping plates 425. Then, the vehicle body 41 is controlled to move back to the previous fault point with the new monitoring device 21.
[0027] When installing the new monitoring device 21, the second electric telescopic rod 431 is extended, causing the second connecting plate 432 to move down to a height level with the base plate 12. The vehicle body 41 is then moved away from the cleaning arm 43 until the second connecting plate 432 is blocked by the base plate 12 and rests against its outer surface. At this point, the monitoring device 21 is aligned with the mounting slot 121. The first electric telescopic rod 422 is then extended, and its output end passes through the first connecting plate 423 and the damping shaft. The stepper motor 424 and clamping plate 425 move the monitoring device 21 downwards, first inserting part of the monitoring device 21 into the mounting slot 121. Then, the stepper motor 421 is controlled to slowly rotate the monitoring device 21. During the rotation, the positioning component aligns the plug-in socket 22 with the slot 122, and then the rotation stops. Next, the first electric telescopic rod 422 is controlled to continue extending, moving the monitoring device 21 downwards until it is inserted into the mounting slot 121. The plug-in socket 22 is then inserted into the slot 122, completing the installation of the new monitoring device 21. Next, the first electric telescopic rod 422 is controlled to continue extending, causing the clamping plate 425 to move downward. Since the monitoring equipment 21 has been installed, the loop at the bottom of the clamping plate 425 will disengage from the hook groove 25 under the guidance of the inner surface of the hook groove 25 as the clamping plate 425 moves downward. Then, the first electric telescopic rod 422 is controlled to quickly shorten, causing the clamping plate 425 to move upward. Due to the damping effect of the damping shaft 424, there will be a delay in the rotation and reset of the clamping plate 425. Therefore, there is no need to worry that the loop at the bottom of the clamping plate 425 will re-engage in the hook groove 25 during the upward movement. Finally, the second electric telescopic rod 431 is controlled to shorten, causing the second connecting plate 432 to reset.
[0028] The replacement of the faulty equipment mentioned above can be manually controlled by the staff through the control panel, or it can be pre-programmed and semi-automatically operated in accordance with the staff's instructions. In addition, the operation procedures for placing the faulty monitoring equipment 21 at the track end installation station and removing the new monitoring equipment 21 are the same as the installation process of the new monitoring equipment 21 and the removal process of the faulty monitoring equipment 21, respectively.
[0029] like Figure 9 and Figure 10 As shown, a cleaning assembly is installed on the second connecting plate 432. The cleaning assembly includes a motor 433 fixedly installed on the bottom surface of the second connecting plate 432. The output end of the motor 433 passes through the second connecting plate 432 and a cleaning plate 434 is fixedly connected thereto. Microfiber bristles are installed on the inner surface of the cleaning plate 434.
[0030] When dirt is found on the transparent protective cover of a monitoring device 21, the vehicle body 41 is moved to that location. First, the second electric telescopic rod 431 is controlled to move the second connecting plate 432 down to its lowest point. Then, the vehicle body 41 is controlled to move away from the cleaning arm 43 until the second electric telescopic rod 431 is blocked by the base plate 12 and abuts against the outer surface of the base plate 12. At this time, the cleaning plate 434 is aligned with the monitoring device 21. The second electric telescopic rod 431 is then shortened so that the cleaning plate 434 is pressed tightly against the transparent protective cover of the monitoring device 21. Then, the motor 433 is controlled to rotate the cleaning plate 434 to clean the dirt on the transparent protective cover. After cleaning, the second electric telescopic rod 431 is first extended to its longest length, then the vehicle body 41 is controlled to move towards the cleaning arm 43, and finally, the second electric telescopic rod 431 is retracted to its shortest length.
[0031] In this invention, when staff in the monitoring room discover a malfunction in a monitoring device 21 through the monitoring screen, the vehicle body 41 is moved along the split track 31 to the location of the malfunctioning monitoring device 21. Upon reaching the malfunction point, the external condition of the monitoring device 21 is observed and recorded using the monitoring camera 428. If it is confirmed that the monitoring device 21 needs to be replaced, the second electric telescopic rod 431 is extended, causing the second connecting plate 432 to move down to a height level with the base plate 12. The vehicle body 41 is then moved away from the cleaning arm 43 until the second connecting plate 432 is... The base plate 12 blocks and abuts against the outer surface of the base plate 12. At this time, the first connecting plate 423 is aligned with the central axis of the monitoring device 21, controlling the extension of the first electric telescopic rod 422. The output end of the first electric telescopic rod 422 drives the clamping plate 425 to move downward through the first connecting plate 423 and the damping shaft 424. If the clamping plate 425 is not aligned with the groove 24 on the clamping seat 23, the stepper motor 421 is controlled to rotate. The output end of the stepper motor 421 drives the first electric telescopic rod 422, the first connecting plate 423 and the damping shaft 424 to rotate until the clamping plate 425 moves downward. The clamping plate 425 is aligned with the groove 24. If it is aligned, continue to control the extension of the first electric telescopic rod 422 to slowly move the clamping plate 425 downward. The bottom end of the clamping plate 425 slides against the inner surface of the groove 24 until the loop hook at the bottom end of the clamping plate 425 is aligned with the hook groove 25. Under the elastic force of the torsion spring 426, the clamping plate 425 moves the loop hook into the hook groove 25. Then, control the first electric telescopic rod 422 to shorten. The clamping plate 425 moves upward as the first electric telescopic rod 422 shortens, first engaging the loop hook in the hook groove 25. The clamping seat 23 is clamped, and then the clamping seat 23 and the monitoring device 21 are moved upward by the loop hook. The monitoring device 21 is pulled out of the slot 122 and the disassembly of the faulty monitoring device 21 is completed. The second electric telescopic rod 431 is shortened to move the second connecting plate 432 upward. Then the vehicle body 41 is moved to the installation position at the end of the track. The faulty monitoring device 21 is put in, and the new monitoring device 21 is taken out and clamped between multiple clamping plates 425. Then the vehicle body 41 is moved back to the previous fault point with the new monitoring device 21. When installing the new monitoring device 21, the second electric telescopic rod 431 is extended, causing the second connecting plate 432 to move down to a height level with the base plate 12. The vehicle body 41 is moved away from the cleaning arm 43 until the second connecting plate 432 is blocked by the base plate 12 and abuts against the outer surface of the base plate 12. At this time, the monitoring device 21 is aligned with the central axis of the mounting slot 121. The first electric telescopic rod 422 is extended, and the output end of the first electric telescopic rod 422 moves the monitoring device 21 down through the first connecting plate 423, the damping shaft 424, and the clamping plate 425. First, part of the monitoring device 21 is inserted into the mounting slot 121. Then, the stepper motor 421 is controlled to drive the monitoring device 21 to rotate slowly. During the rotation, the limiting slot 26 is aligned with the positioning hole 123. At this time, the positioning rod 124 will be pushed out by the elastic force of the return spring, and its curved end will extend into the limiting slot 26, preventing the monitoring device 21 from continuing to rotate. Next, the rotation of the monitoring device 21 is stopped. At this time, due to the limiting slot 26... Align the 6th mounting hole with the positioning hole 123, so the plug-in socket 22 is also aligned with the slot 122. Then, control the first electric telescopic rod 422 to continue extending, causing the monitoring device 21 to move down and be inserted into the mounting slot 121. The plug-in socket 22 is then inserted into the slot 122, completing the installation of the new monitoring device 21. Next, control the first electric telescopic rod 422 to continue extending, causing the clamping plate 425 to move down. Since the monitoring device 21 has been installed in place, the loop hook at the bottom of the clamping plate 425 will be hooked. Guided by the inner surface of the groove 25, the clamping plate 425 moves downward and disengages from the hook groove 25. Then, the first electric telescopic rod 422 is controlled to quickly shorten and drive the clamping plate 425 to move upward. Due to the damping effect of the damping shaft 424, there will be a delay in the rotation and reset of the clamping plate 425. Therefore, there is no need to worry that the loop hook at the bottom of the clamping plate 425 will re-engage in the hook groove 25 during the upward movement. Finally, the second electric telescopic rod 431 is controlled to shorten and drive the second connecting plate 432 to reset. The placement of the fault monitoring device 21 and the removal of the new monitoring device 21 at the track end installation station follow the same operational procedures as the installation process of the new monitoring device 21 and the removal process of the fault monitoring device 21.
