Description

Technical Field

[0001] This invention relates to the technical field of smart park management, and in particular to a smart park intelligent management and control system and equipment based on the Internet of Things. Background Technology

[0002] With the large-scale advancement of smart park construction, intelligent inspection has gradually replaced traditional manual patrols, becoming the core support for park security control and operation and maintenance management. Inspection robots, with their functions such as autonomous navigation, image acquisition, and anomaly recognition, have effectively improved inspection efficiency and reduced labor costs. The sensing devices such as the infrared integrated camera they are equipped with are key components for realizing park environmental monitoring and risk warning. The cleanliness of the infrared integrated camera lens directly determines the image acquisition accuracy and the accuracy of anomaly recognition. The lens cleaning of traditional inspection robots often requires regular manual inspections. Cleaning is carried out after pollution is found, which requires a large investment of manpower, and manual inspection is also subject to delays.

[0003] In the prior art, the invention patent with authorization announcement number CN117817693B discloses a multi-functional security inspection robot for smart parks, including a robot body, a lens, and a conveyor belt. A snap-fit ​​assembly is provided on the side of the conveyor belt, and a housing is provided outside the snap-fit ​​assembly. Inside the housing, a cam and a threaded rod are provided. A turntable is screwed to the end of the threaded rod, and a connecting plate is installed on the outside of the turntable. A cleaning plate is elastically connected to the outside of the connecting plate, and a cleaning blade is connected to the side of the cleaning plate. A telescopic tube is installed between the cleaning plate and the connecting plate, and a sealing block is provided inside the telescopic tube. A ejector pin is provided inside the cleaning plate. During use, the conveyor belt moves the housing to the front of the lens. The cam rotates, pushing the turntable forward. Through the cooperation of the turntable and the threaded rod, the turntable moves the connecting plate closer to the lens, causing the cleaning plate to push against the lens and rotate continuously. Simultaneously, the ejector pin pushes open the sealing block, and lens cleaning fluid from the telescopic tube is sprayed onto the cleaning blade, thus achieving the purpose of cleaning the lens.

[0004] The cleaning units (such as housing, cleaning blades, transmission components, etc.) of the aforementioned prior art are exposed to the outside of the robot body for a long time in a non-clean state, which means that the cleaning units are not well protected and are easily damaged by dust and impurities in the park environment, thus affecting the service life of the cleaning units.

[0005] Existing technologies lack dedicated centralized collection and treatment devices for cleaning solutions sprayed during cleaning and wastewater generated from wiping. Wastewater drips or flows directly onto the park floor and the robot itself, not only polluting the park environment but also potentially corroding equipment components and affecting the service life of the inspection robot. Therefore, it is necessary to provide an IoT-based smart park intelligent management and control system and equipment to solve the above-mentioned technical problems. Summary of the Invention

[0037] Compared with related technologies, the smart park intelligent management and control system and equipment based on the Internet of Things provided by this invention have the following beneficial effects:

[0038] 1. This invention calculates the lens contamination level of the integrated infrared camera in real time through a preset algorithm in the control module. The system determines whether cleaning of the integrated infrared camera has been triggered. When the cleaning unit is triggered, the drive component of the cleaning unit drives the wiper blades of the cleaning component to scrape back and forth. The spray nozzles of the spray components located on both sides of the wiper blades alternately spray cleaning fluid, and a one-way valve ensures that the cleaning fluid is delivered in one direction without backflow. At the same time, the standard deviation is calculated through continuous frame images. This reduces accidental cleaning caused by momentary interference from fallen leaves and birds, and minimizes the ineffective wear and tear on the integrated infrared camera and cleaning unit. It ensures the image acquisition accuracy of the integrated infrared camera while reducing the maintenance costs of manual inspection and cleaning.

[0039] 2. In this invention, the travel component, through the cooperation of the electric cylinder of the lifting component, the vertical slide rod, and the vertical guide slot and horizontal guide slot of the travel guide component, controls the precise movement of the cleaning unit, ensuring that the receiving port and the infrared integrated camera are precisely aligned during cleaning. The cleaning process takes place inside the liquid receiving hopper, so that the wastewater flowing down during the cleaning process flows into the liquid receiving hopper and is collected, which not only avoids wastewater pollution of the park ground environment, but also prevents wastewater dripping and corroding the main body of the inspection robot or other equipment components. In the non-cleaning state, the cleaning unit can be stored in the mounting shell through the travel component. At the same time, the liquid storage tank can seal the avoidance opening of the mounting shell, preventing the cleaning component and the spraying component from being exposed to the park environment for a long time and being damaged by dust and impurities, effectively extending the service life of the cleaning unit.

[0040] 3. In the cleaning unit of the present invention, the wiper blade is driven by a motor to wipe the lens of the infrared integrated camera by reciprocating swing. When the wiper blade swings to one side, the spray nozzle of the spray pipe on the corresponding side sprays out liquid, without the need for other power to deliver the cleaning liquid.

[0041] 4. By using the vertical and horizontal guide slots in the guide plate of the stroke guide component in the stroke component, and cooperating with the first horizontal column of the lifting component, the movement trajectory of the cleaning unit can be precisely controlled, ensuring the positioning accuracy of the cleaning unit and the infrared integrated camera lens.

Detailed Implementation

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Example 1

[0063] Please refer to the following: Figures 1 to 2 A smart park intelligent management and control system based on the Internet of Things includes an infrared integrated camera 3, a control module 6, a park monitoring module 7, and a back-end management center. The control module 6 can communicate with the back-end management center bidirectionally via wireless communication, such as LoRa, NB-IoT, or Wi-Fi.

[0064] The infrared integrated camera 3 is used to collect real-time monitoring images of the park environment;

[0065] Control module 6 controls the infrared integrated camera 3 to acquire real-time images of its own lens area, and calculates the contamination level of the infrared integrated camera 3 lens through a preset algorithm. , The value range is 0-1. The closer to 1, the more severe the pollution, and the more severe the pollution level. Output commands to perform cleaning actions on the three lenses of the infrared integrated camera, cleaning the outer surface of the lens glass;

[0066] The control module 6 controls the start and stop of the inspection robot body 1 according to the cleaning requirements;

[0067] The back-end management center receives in real time the park environmental monitoring images, lens pollution data, the operating status of the inspection robot body 1, and the temperature, humidity, PM2.5, and infrared intrusion detection data collected by the park monitoring module 7 from the control module 6, and stores historical data.

[0068] The back-end management center issues an emergency stop command to control module 6. This command has the highest priority and triggers the main body of the inspection robot 1 to stop moving and the cleaning action of the infrared integrated camera 3 to stop. It also sends inspection path adjustment commands and cleaning parameter calibration commands, including a contamination level determination threshold. Fine-tuning and setting the upper limit for lens cleaning time;

[0069] When the park monitoring module 7 detects abnormal data, such as PM2.5 > 500 μg / m³, infrared intrusion triggering, or when the control module 6 reports that the lens contamination level is still high after three consecutive cleanings... When a cleaning failure message is received, an audible and visual alarm is automatically triggered, and the alarm information is pushed to the backend management center.

[0070] The back-end management center displays real-time inspection footage, environmental data for each area, and equipment operating status. It supports daily, weekly, and monthly statistics on lens contamination frequency, inspection coverage, and the number of abnormal events.

[0071] Furthermore, the control logic of control module 6 includes: when control module 6 calculates the lens contamination level using a preset algorithm... Immediately, a stop command is sent to the motion mechanism of the inspection robot body 1, and a cleaning command is sent to the lens of the infrared integrated camera 3. When the control module 6 detects through the preset algorithm... When the cleaning of the infrared integrated camera 3 lens is completed, the system automatically sends a start command to the motion mechanism of the inspection robot body 1 to resume normal operation of the inspection robot body 1 without human intervention. If the back-end management center sends an emergency stop command, the control module 6 will prioritize controlling the inspection robot body 1 to stop moving and stop cleaning the camera 3 to ensure equipment safety.

[0072] Furthermore, control module 6 calculates the lens contamination level of the integrated infrared camera 3. This includes the following steps:

[0073] Step 1: Control module 6 controls infrared integrated camera 3 to acquire one frame of real-time image every 2 seconds according to a preset cycle. The image resolution is not less than 1920×1080. The acquisition object covers the lens area of ​​infrared integrated camera 3 and the park environment area to avoid repeated acquisition and occupy hardware resources. The image mode switching is triggered by the light sensor built into infrared integrated camera 3. During the day, color images in normal mode are acquired. All acquired color images are converted into grayscale images before processing. At night, grayscale images in infrared mode are acquired and used directly as grayscale images without additional conversion, ensuring the consistency of the data basis for algorithm processing. After receiving the image data, control module 6 first runs the embedded image processing program pre-stored in its memory. According to the standard brightness formula: such as Y=0.299R+0.587G+0.114B or by directly reading the infrared image as a grayscale image, the acquired images are uniformly converted into single-channel grayscale images.

[0074] Step 2: Control module 6 performs a 3×3 standard Gaussian filter on the single-channel grayscale image converted in Step 1. The filter convolution kernel weight matrix is ​​as follows: The processing method is as follows: For the grayscale value of each pixel in the image, multiply it by the weight at the corresponding position of the convolution kernel, sum the results, and then divide by 16 to normalize the total weight sum. The normalization calculation formula is: ,in, This represents the new grayscale value of the target pixel after filtering. In a 3×3 convolution kernel, the first... line, number Fixed weights for columns; this preprocessing is used to eliminate isolated noise caused by dust particles and air vibrations in the outdoor environment of the park, preventing these types of noise from being misjudged as contaminated pixels, and providing clean image data for subsequent feature calculations;

[0075] Step 3: Control module 6 calculates the percentage of polluted areas in the first dimension of pollution characteristics using the following formula. :

[0076]

[0077] In the formula, The total number of valid contaminated pixels is determined by the following criteria: a grayscale value < 50 corresponds to lens dark spot contamination, or a grayscale value > 200 corresponds to lens bright spot contamination. Furthermore, the 3×3 pixel block centered on the contaminated pixel must contain at least four of these grayscale aberration pixels to exclude false positives from isolated noise points. The total number of pixels in the image captured by the infrared integrated camera 3;

[0078] pass Quantify the coverage area of ​​the contaminated area of ​​the infrared integrated camera 3 lens as the core basis for determining whether the infrared integrated camera 3 needs to be cleaned;

[0079] Step 4: Control module 6 calculates the attenuation rate of edge sharpness of the second-dimensional pollution feature according to the following formula. :

[0080]

[0081] In the formula, The mean edge sharpness response of the real-time image is calculated using a 3×3 discrete template. The Laplacian operator performs edge detection, filtering out valid edge pixels with an absolute value of second-order grayscale change ≥ 20 and excluding minor grayscale changes in non-edge areas. The threshold of ≥ 20 for the Laplacian operator's second-order grayscale change value is determined by comparing the edge response differences between clean and contaminated lenses: the average edge grayscale change of the clean lens is 45±5, while the average edge grayscale change of slightly blurred contaminated lenses is reduced to 22±3. Setting it to ≥ 20 can ensure that more than 90% of slightly blurred contamination is detected, avoiding missed detections.

[0082] Then, take the arithmetic mean of the grayscale changes of all valid edge pixels, and perform... The calculation formula is as follows: ;

[0083] in, The number of effective edge pixels, This represents the second-order grayscale variation value; The baseline value for edge sharpness of the infrared integrated camera 3 in a clean state;

[0084] The pre-storage process involves wiping the lens with a lint-free cloth until no visible stains are visible before the equipment leaves the factory, and then continuously acquiring 5 frames each in normal light and dark infrared environments. The calculation method yields 5 baseline values ​​for normal mode and 5 baseline values ​​for infrared mode. The arithmetic mean of the 5 values ​​for normal mode and the 5 values ​​for infrared mode are then calculated and stored in control module 6. Control module 6 then calls the corresponding... ;

[0085] pass To quantify the loss of clarity caused by lens contamination in the 3-lens integrated infrared camera and compensate for it. The defect of failing to detect slightly ambiguous types of contamination;

[0086] Step 5: Control module 6 is fused according to the following formula and To obtain the final pollution level :

[0087]

[0088] In the formula, For the final lens contamination level, The value range is 0-1. The closer the value is to 1, the more severe the pollution. A value closer to 0 indicates a cleaner lens; 0.6 and 0.4 are weighting coefficients, and their allocation is based on the priority requirements of smart park inspection scenarios, assigning characteristics based on the proportion of contaminated areas. Higher weighting makes the system more sensitive to coverage contamination, as the coverage area of ​​the contaminated area is a core criterion for initiating cleaning in park inspection scenarios. Excessive coverage directly impacts the accuracy of park image monitoring. The weight is increased by 0.4 because slight blurring only affects accuracy when the coverage area is small;

[0089] Step Six: Control module 6 continuously acquires 3 frames of images, and calculates the final contamination level 3 times according to steps two, three, four, and five respectively. , recorded as Then calculate 3 times using the following formula. Standard deviation of values :

[0090]

[0091] In the formula, These correspond to the final pollution levels calculated in the 1st, 2nd, and 3rd calculations, respectively. The standard deviation of the three pollution levels is used to determine whether the data is stable. The arithmetic mean of three pollution levels;

[0092] like If the data is stable, it is used to eliminate momentary occlusion interference such as falling leaves or birds flying across the lens, and outputs the final pollution level. ;

[0093] like If the data is transient, discard the current three data points, and start collecting and calculating again from step one until the output is stable. value;

[0094] The above verification can reduce the false start of cleaning caused by momentary interference, thereby reducing equipment wear and energy consumption;

[0095] The infrared integrated camera 3, control module 6, and park monitoring module 7 in this system are physically corresponding to the infrared integrated camera 3, control module 6, and park monitoring module 7 installed in the equipment section, respectively. The system functions are realized through the above-mentioned hardware entities.

The first eccentric rod 413 is slidably arranged in the first elongated slot 4151. The liquid inlet cylinder 416 is fixedly connected to the inner wall of the liquid receiving hopper 4111. A receiving port 4112 is opened through the side of the liquid receiving hopper 4111 near the infrared integrated camera 3. The receiving port 4112 is correspondingly set and matched with the size of the infrared integrated camera 3. The clearance port 201 is correspondingly set and matched with the size of the liquid storage tank 4110. A wiper blade 414 is fixedly connected to the side of the swing rod 412 facing the infrared integrated camera 3. After the wiper blade 414 is aligned with the lens of the infrared integrated camera 3, it can fit against the outer surface of the lens glass.

[0105] In the above-mentioned case, the liquid storage tank 4110 can be made of stainless steel, or a multi-functional protective coating can be provided on the top outer surface of the liquid storage tank 4110. This coating is preferably hydrophobic and oleophobic, and also possesses good wear resistance and UV aging resistance. The sealed sliding fit between the piston plate 417 and the inlet cylinder 416 prevents leakage of the cleaning fluid and ensures stable pressure during suction and pushing. The vent hole of the inlet cylinder 416 can balance the internal air pressure, ensuring smooth movement of the piston plate 417. This can be further enhanced by embedding a sealing strip on the inner wall of the receiving port 4112. The waterproof performance between the inner wall and the contact surface of the infrared integrated camera 3 is improved. At the same time, the size of the receiving port 4112 is adapted to the infrared integrated camera 3. Combined with the fitting design of the wiper blade 414 and the lens glass of the infrared integrated camera 3, it can more comprehensively cover the cleaning area. While the clearance port 201 is adapted to the liquid storage tank 4110, the inner side wall of the clearance port 201 can improve the dustproof performance between the contact surface with the liquid storage tank 4110 by embedding a sealing strip, which can prevent external dust from entering the interior of the mounting shell 2 and protect the internal components.

[0106] Furthermore, the spraying component 42 includes a delivery hose 421, the inlet end of which is connected to the outlet end of the liquid outlet pipe 419. Two liquid delivery chambers 423 are symmetrically opened inside the swing arm 412. The two delivery hoses 421 correspond one-to-one with the two liquid delivery chambers 423. The outlet end of the delivery hose 421 is connected to the corresponding liquid delivery chamber 423. The length of the delivery hose 421 can meet the movement requirements of the swing arm 412 when it swings. Two spray pipes 422 are symmetrically fixedly connected to both sides of the swing arm 412. Several spray nozzles 424 that communicate with the inside of the spray pipes 422 are fixedly connected at equal intervals from top to bottom on the pipe wall of the spray pipes 422. The outlet end of the spray nozzles 424 faces the position where the wiper blade 414 contacts the outer surface of the lens glass of the infrared integrated camera 3.

[0107] As described above, the length of the delivery hose 421 is adaptable to flexibly accommodate the reciprocating swing amplitude of the swing arm 412, avoiding pulling or tangling that could affect the cleaning action. The two liquid delivery chambers 423 are set one-to-one with the spray pipe 422, enabling the diversion and delivery of cleaning fluid. The spray nozzles 424 are evenly distributed from top to bottom, allowing the cleaning fluid to cover the lens surface more evenly. Combined with the wiping action of the wiper blade 414, the cleaning efficiency is improved. At the same time, the design of the spray nozzles 424 facing the contact position allows the wiper blade 414 to quickly contact the cleaning fluid to clean the lens glass of the infrared integrated camera 3.

[0108] Furthermore, the drive component 43 includes a main swing arm 431, the top end of which is fixedly connected to the other end of the rotating shaft 411. A second elongated slot 432 is transversely opened on the main swing arm 431. A motor 433 is fixedly installed on the outer wall of the liquid receiving hopper 4111 via a mounting bracket. The motor 433 can be a geared motor. A fixed rod 434 is fixedly connected to the rotating end of the motor 433. A second eccentric rod 435 is rotatably connected to one end of the fixed rod 434. The second eccentric rod 435 is slidably disposed in the second elongated slot 432. A drain hose 4113 communicating with the bottom of the liquid receiving hopper 4111 is fixedly connected to it. A collection box 4114 is fixedly installed inside the mounting shell 2. The bottom end of the drain hose 4113 is connected to the collection box 4114. A drain valve is also installed on the collection box 4114. An openable door is also installed on the side wall of the mounting shell 2.

[0109] In the above, the geared motor 433 can provide a stable and controllable speed, ensuring that the swing amplitude of the main swing rod 431 and the swing rod 412 is more uniform. The sliding cooperation between the second eccentric rod 435 and the second long slot 432 smoothly converts the circular motion of the motor 433 into reciprocating oscillation. The cooperation between the drain hose 4113 and the collection box 4114 can realize the centralized collection of clean sewage. The openable design of the drain valve and the mounting shell 2 facilitates the subsequent sewage treatment and cleaning of the collection box 4114, which meets the environmental protection requirements of the smart park.

[0110] Furthermore, the one-way valve 44 includes a frame 441, which is fixedly connected to the inner wall of the inlet pipe 418. Two symmetrical openings 442 are provided on the frame 441. Two valve plates 443 are symmetrically arranged on one side of the frame 441. A pin 445 is fixedly connected to the valve plate 443, and the end of the pin 445 is rotatably connected to the inner side of the inlet pipe 418. The two valve plates 443 correspond one-to-one with the two openings 442. When one side of the valve plate 443 is in contact with the frame 441, the frame 441 blocks the valve plate 443, and the valve plate 443 controls the corresponding opening 442. 42 is used for sealing. A spring strip 444 is provided on one side of the valve plate 443. One end of the spring strip 444 is fixedly connected to the side wall of the valve plate 443, and the other end of the spring strip 444 is fixedly connected to the side wall of the frame 441. The one-way valve 44 in the outlet pipe 419 has the same structure as the one-way valve 44 in the inlet pipe 418, but the flow direction is opposite. The flow direction of the one-way valve 44 in the inlet pipe 418 is from the storage tank 4110 to the inlet cylinder 416, and the flow direction of the one-way valve 44 in the outlet pipe 419 is from the inlet cylinder 416 to the delivery hose 421, so as to realize the one-way delivery of the cleaning fluid.

[0111] In the above, the elastic reset function of the spring strip 444 drives the valve plate 443 to tightly seal the port 442 when there is no liquid pressure, ensuring the sealing effect. The flow directions of the one-way valve 44 in the inlet pipe 418 and the outlet pipe 419 are opposite, forming a one-way delivery channel for the cleaning fluid from the storage tank 4110 → inlet pipe 418 → inlet cylinder 416 → outlet pipe 419 → delivery hose 421, avoiding backflow of the cleaning fluid and ensuring continuous supply and stable pressure.

[0112] Furthermore, the stroke component 5 includes a lifting component 51 and a stroke guide component 52. The lifting component 51 includes a connecting bar 511, one end of which is fixedly connected to the lower outer wall of the liquid receiving hopper 4111, and the other end of which is fixedly connected to a support plate 512. Two first horizontal columns 513 are rotatably connected transversely through the support plate 512. Two connecting rods 514 are symmetrically rotatably sleeved on the outer sides of both ends of the two first horizontal columns 513. One end of the connecting rod 514 is fixedly connected to a second horizontal column 515. The column 515 is arranged parallel to the first horizontal column 513. An electric cylinder 517 is fixedly connected to the bottom inner side of the mounting shell 2. A transmission frame 516 is fixedly connected to the telescopic end of the electric cylinder 517. A vertical cylinder 518, which is parallel to the electric cylinder 517, is also fixedly connected to the bottom inner side of the mounting shell 2. A vertical slide rod 519 is slidably connected to the inner side of the vertical cylinder 518. The top end of the vertical slide rod 519 extends out of the vertical cylinder 518 and is fixedly connected to the bottom of the transmission frame 516. All four second horizontal columns 515 are rotatably connected to the transmission frame 516.

[0113] In the above, the sliding engagement between the vertical slide bar 519 and the vertical cylinder 518 is used to limit the movement direction of the transmission frame 516, prevent deviation during lifting and lowering, and improve movement stability. The four connecting rods 514 are rotatably connected to the first horizontal column 513 and the second horizontal column 515 to form a parallelogram transmission structure, ensuring that the support plate 512 remains horizontal during lifting and moving, thereby ensuring the stability of the cleaning unit 4 and improving the docking accuracy with the infrared integrated camera 3.

[0114] Furthermore, the stroke guide component 52 includes a guide plate 521. One side of the guide plate 521 is fixedly connected to the inner wall of the mounting shell 2. Two guide plates 521 are symmetrically arranged. Each guide plate 521 has two sets of guide grooves. The guide grooves include vertical guide groove holes 522 and horizontal guide groove holes 523. Both the vertical guide groove holes 522 and the horizontal guide groove holes 523 are horizontally opened through the guide plate 521. The top end of the vertical guide groove hole 522 is connected to one end of the horizontal guide groove hole 523. The connection between the vertical guide groove hole 522 and the horizontal guide groove hole 523 is provided with a rounded corner for transition. The ends of the first horizontal column 513 are slidably arranged in the guide grooves on the corresponding sides. The second horizontal column 515 is arranged corresponding to the vertical center line of the vertical guide groove hole 522 to ensure that when the electric cylinder 517 is driven, the second horizontal column 515 moves along the vertical line, thereby driving the first horizontal column 513 to smoothly slide into the vertical guide groove hole 522.

[0115] In the above, the connection and cooperation between the vertical guide slot 522 and the horizontal guide slot 523 guides the movement trajectory of the first horizontal column 513, realizing the orderly stroke switching of the cleaning unit 4 first lifting and then moving horizontally. The rounded transition at the connection point can reduce the frictional resistance of the first horizontal column 513 during trajectory switching, reduce component wear, and improve service life. The symmetrical arrangement of the two guide plates 521 limits the first horizontal column 513 from both sides, further improving the stability of movement.

[0116] Furthermore, the park monitoring module 7 includes a temperature and humidity sensor, a PM2.5 sensor, an infrared intrusion sensor, and a sound monitoring sensor; the infrared integrated camera 3, the park monitoring module 7, the motor 433, and the electric cylinder 517 are all electrically connected to the control module 6, and the control module 6 is electrically connected to the power module built into the inspection robot body 1.

[0117] The integration of multiple types of sensors, such as temperature and humidity sensors and PM2.5 sensors, collects environmental data from the park, providing rich monitoring data for the back-end management center. The electrical connection between the park monitoring module 7, motor 433, electric cylinder 517, and control module 6 enables intelligent control of cleaning actions and monitoring data transmission.

[0129] The working principle of the smart park intelligent management and control system and equipment based on the Internet of Things provided by this invention is as follows:

[0130] During the routine inspection of the park, cleaning unit 4 is in a retracted state: the storage tank 4110 is pre-filled with cleaning fluid, and the control module 6 controls the telescopic end of the electric cylinder 517 to retract downwards. The electric cylinder 517 drives the transmission frame 516 to move downwards. When the transmission frame 516 moves downwards, the vertical slide rod 519 slides downwards along the vertical cylinder 518, making the transmission frame 516 move downwards stably. When the transmission frame 516 moves downwards, it drives the second horizontal column 515 to move downwards. The second horizontal column 515 drives the connecting rod 514 to move. Since the transmission frame 516 remains vertically downwards, the connecting rod 514 pulls the first horizontal column 513 to move the support plate 512. Under the guidance of the horizontal guide slot 523, the downward movement of the transmission frame 516 causes the first horizontal column 513 to slide along the horizontal guide slot 523, thereby causing the support plate 512 to move laterally. The support plate 512 drives the connecting strip 511 to move the liquid receiving hopper 4. 111 moves laterally, causing the liquid receiving hopper 4111 to move away from the infrared integrated camera 3, thus moving the receiving port 4112 away from the infrared integrated camera 3. When the first horizontal column 513 moves along the horizontal guide slot 523 to the top of the vertical guide slot 522, the liquid storage tank 4110 moves to the top of the clearance port 201. The telescopic end of the electric cylinder 517 continues to retract, and the first horizontal column 513 maintains vertical movement under the guidance of the vertical guide slot 522, thus keeping the support plate 512 moving vertically downward, so that the liquid storage tank 4110 continues to move downward until all the components in the cleaning unit 4 located below the liquid storage tank 4110 enter the mounting shell 2, and the liquid storage tank 4110 also enters the clearance port 201, until the liquid storage tank 4110 blocks the clearance port 201. At this time, the liquid storage tank 4110 moves to the lowest position and does not block the lens of the infrared integrated camera 3.

[0131] The infrared integrated camera 3 collects images according to a preset cycle: during the day, it triggers the normal mode through its built-in light sensor to collect color images, and at night, it triggers the infrared mode to collect grayscale images. All images are converted into single-channel grayscale images by the control module 6, covering both the lens area and the park environment area, thus avoiding repeated collection and resource consumption.

[0132] The park monitoring module 7 on the top of the housing 2 collects data. The monitoring data is uploaded to the back-end management center by the control module 6 via wireless communication. The back-end management center stores historical data in real time and displays real-time inspection screens for back-end management personnel to view.

[0133] Control module 6 processes the acquired grayscale image and calculates the lens contamination level. The standard deviation was calculated by continuously acquiring three frames of images. ,like and The control module 6 immediately sends a stop command to the motion mechanism of the inspection robot body 1 to start the cleaning process; if the back-end management center issues an emergency stop command, the inspection robot body 1 and the cleaning action will be stopped first.

[0134] During cleaning, the control module 6 controls the extension end of the electric cylinder 517 to extend upwards. The electric cylinder 517 pushes the transmission frame 516 to move upwards, thereby causing the first horizontal column 513 to move upwards along the vertical guide slot 522. As the first horizontal column 513 moves upwards within the vertical guide slot 522, the support plate 512 remains vertically upwards, thereby driving the cleaning component 41 to move upwards through the connecting strip 511 until the first horizontal column 513 moves from the bottom end to the top end of the vertical guide slot 522. At this time, the receiving opening 4112 is directly opposite the lens of the infrared integrated camera 3. The extension end of the electric cylinder 517 continues to extend, and the first horizontal column 513 moves laterally along the horizontal guide slot 523, thereby driving the liquid receiving bucket 4111 to move laterally towards the infrared integrated camera 3 until the liquid receiving bucket 4111 is fitted onto the outside of the infrared integrated camera 3 through the receiving opening 4112, and the outer surface of the lens glass of the infrared integrated camera 3 is in contact with the wiper blade 414.

[0135] After the wiper blade 414 contacts the outer surface of the lens glass of the infrared integrated camera 3, the control module 6 controls the motor 433 to start. The motor 433 drives the fixed rod 434 to make the second eccentric rod 435 move in a circular motion. The second eccentric rod 435 moves in the second long slot 432, which in turn drives the main swing rod 431 to swing back and forth. The main swing rod 431 drives the swing rod 412 to swing back and forth synchronously through the rotating shaft 411. The swing rod 412 drives the wiper blade 414 to swing back and forth to clean the outer surface of the lens glass of the infrared integrated camera 3. During the swinging process of the swing rod 412, the first eccentric rod 413 is driven to swing back and forth synchronously. The first eccentric rod 413 reciprocates within the first elongated slot 4151, thereby driving the cross rod 415 to slide laterally. The cross rod 415 drives the piston plates 417 within the two inlet cylinders 416 to move. When the piston plates 417 within the inlet cylinders 416 move away from the inlet pipe 418, the valve plate 443 of the one-way valve 44 within the inlet pipe 418 opens, the spring strip 444 is elastically compressed, and the one-way valve 44 within the outlet pipe 419 is closed. The cleaning fluid in the storage tank 4110 enters the inlet cylinders 416 through the inlet pipe 418. When the cross rod 415 drives the piston plates 417 to move closer to the inlet pipe 418... During directional movement, the one-way valve 44 in the inlet pipe 418 closes, while the valve plate 443 of the one-way valve 44 in the outlet pipe 419 opens, allowing the cleaning fluid in the inlet cylinder 416 to enter the outlet pipe 419 through the port 442, then through the delivery hose 421 into the delivery chamber 423, and finally into the spray pipe 422. The cleaning fluid is then sprayed onto the lens surface of the infrared integrated camera 3 through the spray nozzle 424. The lens surface of the infrared integrated camera 3 is cleaned by simultaneously spraying the cleaning fluid and wiping it with the wiper blade 414. Furthermore, the reciprocating push and pull of the two piston plates 417 causes the wiper blade 414 to swing to one side, thus cleaning the lens surface. The spray pipe 422 on one side sprays cleaning fluid through the spray nozzle 424. When the wiper blade 414 swings to the other side, the spray pipe 422 on the other side sprays cleaning fluid through the spray nozzle 424 for wiping. This achieves the alternating spraying of cleaning fluid by the two sets of spray pipes 422. That is, when the wiper blade 414 swings to one side, the corresponding spray pipe 422 sprays fluid, and when it swings in the opposite direction, the other side sprays fluid, which improves cleaning efficiency. Wastewater generated during the cleaning process is collected by the liquid receiving hopper 4111 and flows into the collection box 4114 inside the mounting housing 2 through the drain hose 4113 at the bottom of the liquid receiving hopper 4111. The collection box 4114 is equipped with a drain valve and is cleaned periodically through the openable door on the side wall of the mounting housing 2.

[0136] During this process, the lens contamination level of the infrared integrated camera 3 is monitored in real time by the control module 6. When three consecutive frames of images are calculated and When cleaning is completed, the electric cylinder 517 is controlled to retract its telescopic end, driving the cleaning unit 4 to be stored in the mounting shell 2 along the path. At the same time, an start command is sent to the main body 1 of the inspection robot to resume the park inspection.

[0137] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
