Description
Technical Field
[0001] The present invention relates to a vehicle-mounted high-altitude camera cleaning device and a cleaning method. Specifically, the cleaning method adopts the steps of first identifying and calculating the features and posture of a camera, then adjusting the end of the cleaning device to align with the camera, then cleaning the camera by controlling the start and stop of a pump valve, and finally identifying the cleanliness of the camera mirror after cleaning and providing feedback on whether it needs to be cleaned again. The cleaning method is installed with a rotating table, a liquid inlet shell and a recovery device with a special structure, and belongs to the field of cleaning equipment. Background Art
[0002] In recent years, the number of high-altitude cameras used to monitor road safety in my country has continued to increase, and the popularity of private cars has also caused the exhaust gas content in the air to continue to increase. The carbon deposits and oily substances in the exhaust gas will adhere to the camera, affecting the camera's image quality and bringing many inconveniences to road safety work.
[0003] High-altitude cameras are usually installed at a height of 5 to 7 meters above the ground. They are often arranged in rows on roads at different angles and are often arranged at intervals of 50 meters in tunnels, which brings great difficulties to daily cleaning work. At present, there are three main methods for on-site cleaning of high-altitude cameras: First, the road management party currently dispatches maintenance personnel to the site for manual cleaning. This method usually uses a lifting platform to lift people to 3-4 meters above the ground, and people use high-pressure water guns to wash the camera. The cleaning effect is poor, the efficiency is low, it is time-consuming and labor-intensive, the safety is poor, and the labor maintenance cost is high; the second is the semi-automatic cleaning device in the existing technology, which usually needs to be manually pushed to the designated position and the position of the cleaning device is adjusted to the best cleaning position for cleaning. The best cleaning position depends on human experience, which is time-consuming and labor-intensive, inefficient, poor consistency, and high maintenance cost; the third is the existing technology of fixed installation of a timed cleaning device at the camera installation location. This type of cleaning device requires one-to-one installation, which is costly, and the wiper strip cleaning device is prone to aging and has poor cleaning effect. The water spray cleaning device requires irregular addition of cleaning fluid and has high requirements for the safety of installation and fixation.
[0004] Existing technologies also include vehicle-mounted cleaning devices for high-altitude street lamps in tunnels, but there are significant differences between the devices and methods for cleaning street lamps and cameras. For example, street lamps are usually installed on the top or side walls of tunnels, and their lighting direction is perpendicular to the driving direction, which facilitates the cleaning device to identify, avoid obstacles and adjust the posture of street lamps, while cameras are installed above the driving lane and the lens direction is the same as the driving direction, which brings great interference and challenges to identification, obstacle avoidance and posture adjustment; compared with street lamps, cameras have smaller targets and smaller mirrors, and the installation angles of different cameras vary greatly. Only advanced detectors and advanced algorithms can meet actual cleaning needs, otherwise there will be large detection and recognition errors, which will make the cleaning effect worse; compared with street lamps, cameras have higher sealing requirements, which makes the requirements for the cleaning process different.
[0005] In addition, there are some problems with the existing cleaning methods. For example, only flushing with water cannot completely clean the contaminants that have been adhering to the lens surface for a long time. The method of flushing the camera after mixing the cleaning agent with the cleaning liquid cannot make the cleaning agent and the contaminants fully react, and the cleaning agent will remain on the camera mirror, corroding the sealing ring on the lens to varying degrees, reducing the sealing of the camera. Wiping the camera will damage the camera lens to varying degrees and change the original position of the camera. It has high requirements for the wiping position and strength, and it takes a long time. According to field research, because the camera is turned on for a long time, the mirror temperature is high, which is enough to quickly evaporate the liquid remaining on the lens surface. Installing a blow-drying device will blow the solid particles of pollutants floating in the air onto the mirror surface, and make the structure of the cleaning device complicated and time-consuming. The existing cleaning devices and cleaning methods either have no feedback on the cleanliness of the mirror after cleaning or use manual feedback. There is no closed-loop feedback method that integrates advanced detectors with advanced algorithms.
[0006] Therefore, the existing cleaning devices and cleaning methods cannot meet the high-precision and high-efficiency cleaning requirements of high-altitude cameras. There is an urgent need for a cleaning device and cleaning method for high-altitude cameras that are more intelligent, safer and more efficient, have better consistency in cleaning methods, more significant cleaning effects, closed-loop feedback on cleaning effects, and are easier to store.

[0013] The present invention also provides a vehicle-mounted high-altitude camera cleaning method, comprising the following steps:
[0014] Step 1: Before the cleaning operation begins, the cleaning device is in a storage state (such as Figure 3 As shown), fill the water tank and the detergent tank with clean water and detergent respectively, start the metering pump A and the metering pump B, at this time, the solenoid valve A and the solenoid valve B are in the closed state, the overflow valve A and the overflow valve B open the valve core under the pressure, the clean water and the detergent flow back to the water tank and the detergent tank through the clean water overflow pipe and the detergent overflow pipe respectively, pull the clean water telescopic pipe, the detergent telescopic pipe and the recovery device telescopic rod out of the liquid inlet shell and the recovery device fixed shaft sleeve to the longest, the driver parks the car obliquely below the monitoring camera, and roughly adjusts the height of the lifting platform according to the installation height of the monitoring camera, so that the cleaning device is within the washable height range of the camera, presses the standby button in the cab, and the motor B rotates to put the cleaning device in the standby state (as shown in the figure). Figure 4 shown).
[0015] Step 2: Press the cleaning start button in the cab. The binocular camera that has been pre-trained based on deep learning recognizes and calculates the features and posture of the surveillance camera and transmits the results to the controller. The controller drives motor A, motor B and motor C to rotate, so that the rotating table, rotating sleeve and rotating shaft rotate, and at the same time drives the two cylinder telescopic rods to extend and retract, so that the cleaning agent atomizing nozzle is aimed at the center of the lens of the surveillance camera.
[0016] Step three, after two seconds, the controller sends a signal to solenoid valve B to open the valve core of solenoid valve B, and then closes after waiting for one second. During the period of opening and closing the valve core, the cleaning agent flows into the liquid inlet shell through the cleaning agent outbox straight pipe, the cleaning agent outbox hose, the cleaning agent inlet hose and the cleaning agent inlet straight pipe, and flows to the cleaning agent atomizing nozzle through the liquid inlet shell and the cleaning agent telescopic pipe. The cleaning agent is evenly sprayed on the camera mirror surface to react with the pollutants after high-pressure atomization. Then the cleaning agent keeps overflowing. After waiting for ten seconds, the controller sends a signal to solenoid valve A to open the valve core of solenoid valve A, and then closes after waiting for three seconds. During the period of opening and closing the valve core Clean water flows into the liquid inlet shell through the clean water outlet straight pipe, the clean water outlet hose, the clean water inlet hose and the clean water inlet straight pipe, and flows to the high-pressure water nozzle through the liquid inlet shell and the clean water telescopic pipe. The clean water is sprayed onto the camera mirror after being pressurized. During this period, the motor C drives the terminal cleaning device to swing within the range of -20 degrees to 20 degrees to increase the flushing area, and the reacted pollutants and residual cleaning agents on the mirror are rinsed clean. The sewage after flushing will fall on the recovery device funnel, and flow into the sewage tank through the recovery device straight pipe, the recovery device hose, the sewage inlet hose and the sewage inlet straight pipe, and then the clean water also keeps overflowing.
[0017] Step 4: Based on deep learning, the binocular camera that has been pre-trained for the mirror contamination condition of the surveillance camera judges the cleanliness of the mirror of the cleaned surveillance camera. If the mirror cleanliness does not meet the cleaning standard, step 3 is repeated until the mirror cleanliness meets the cleaning standard; if the mirror cleanliness meets the cleaning standard, the cleaning device automatically returns to the standby state, and the remaining clean water on the mirror will be quickly evaporated by the temperature of the mirror.
[0018] Step 5. If this is the last camera, the driver presses the stop cleaning button, the cleaning device returns to the storage state, and the water telescopic tube, the cleaning agent telescopic tube and the recovery device telescopic rod are retracted to the storage state; if it is not the last camera, the driver drives forward to the next camera, and then performs steps 2, 3 and 4 until the last surveillance camera is cleaned.

After waiting for ten seconds, the controller sends a signal to the solenoid valve A39 to open the valve core of the solenoid valve A39, and waits for three seconds before closing. During the opening and closing of the valve core, the clean water flows through the cleaning agent outlet straight pipe 43, the cleaning agent outlet hose 47, the cleaning agent shell inlet hose 24 and the cleaning agent shell inlet straight pipe 23.

The sewage after flushing will fall on the recovery device funnel 31, and flow into the sewage tank 48 through the recovery device straight pipe 32, the recovery device hose 33, the sewage inlet hose 50 and the sewage inlet straight pipe 49, and then the clean water also keeps overflowing.
[0038] Step 4: Based on deep learning, the binocular camera 27 that has been pre-trained for the mirror contamination condition of the surveillance camera determines the cleanliness of the mirror of the surveillance camera after cleaning. If the mirror cleanliness does not meet the cleaning standard, repeat step 3 until the mirror cleanliness meets the cleaning standard; if the mirror cleanliness meets the cleaning standard, the cleaning device automatically returns to the standby state, and the remaining clean water on the mirror will be evaporated by the temperature of the mirror in a relatively short time.
[0039] Step 5. If this is the last camera, the driver presses the stop cleaning button, the cleaning device returns to the storage state, and the water telescopic tube 21, the cleaning agent telescopic tube 25 and the recovery device telescopic rod 29 are retracted to the positions when they are in the storage state; if it is not the last camera, the driver drives forward to the next camera, and then performs steps 2, 3 and 4 until the last surveillance camera is cleaned.

4. A method for cleaning a vehicle-mounted high-altitude camera, using a vehicle-mounted high-altitude camera cleaning device as claimed in any one of claims 1 to 3, characterized in that: The following steps are involved: Step 1: Before the cleaning operation begins, the cleaning device is in storage state. Fill the water tank and the cleaning agent tank with clean water and cleaning agent respectively, start metering pump A and metering pump B. At this time, solenoid valve A and solenoid valve B are in closed state. The valve cores of overflow valve A and overflow valve B are opened under pressure. Clean water and cleaning agent flow back to the water tank and cleaning agent tank through the clean water overflow pipe and the cleaning agent overflow pipe respectively. Pull out the clean water telescopic pipe, the cleaning agent telescopic pipe and the recovery device telescopic rod from the liquid inlet shell and the recovery device fixed shaft sleeve to the longest length respectively. The driver parks the car obliquely below the surveillance camera and roughly adjusts the height of the lifting platform according to the installation height of the surveillance camera so that the cleaning device is within the washable height range of the camera. Press the standby button in the cab, and the motor B rotates to put the cleaning device in standby state. Step 2: Press the cleaning start button in the cab. The binocular camera pre-trained based on deep learning recognizes and calculates the features and posture of the surveillance camera and transmits the results to the controller. The controller drives motor A, motor B and motor C to rotate, so that the rotating table, rotating sleeve and rotating shaft rotate, and at the same time drives the two cylinder telescopic rods to extend and retract, so that the cleaning agent atomizing nozzle is aimed at the center of the surveillance camera lens; Step three, after two seconds, the controller sends a signal to solenoid valve B to open the valve core of solenoid valve B, and then closes after waiting for one second. During the period of opening and closing the valve core, the cleaning agent flows into the liquid inlet shell through the cleaning agent outbox straight pipe, the cleaning agent outbox hose, the cleaning agent inlet hose and the cleaning agent inlet straight pipe, and flows to the cleaning agent atomizing nozzle through the liquid inlet shell and the cleaning agent telescopic pipe. The cleaning agent is evenly sprayed on the camera mirror surface to react with the pollutants after high-pressure atomization. Then the cleaning agent keeps overflowing. After waiting for ten seconds, the controller sends a signal to solenoid valve A to open the valve core of solenoid valve A, and then closes after waiting for three seconds. During the period of opening and closing the valve core Clean water flows into the liquid inlet shell through the clean water outlet straight pipe, the clean water outlet hose, the clean water inlet hose and the clean water inlet straight pipe, and flows to the high-pressure water nozzle through the liquid inlet shell and the clean water telescopic pipe. The clean water is sprayed on the camera mirror after being pressurized. During this period, the motor C drives the terminal cleaning device to swing within the range of -20 degrees to 20 degrees to increase the flushing area, and the pollutants and residual cleaning agents reacted on the mirror are rinsed clean. The sewage after flushing will fall on the recovery device funnel, and flow into the sewage tank through the recovery device straight pipe, the recovery device hose, the sewage inlet hose and the sewage inlet straight pipe, and then the clean water also keeps overflowing; Step 4: Based on deep learning, a recognition camera pre-trained for the contamination status of the mirror of the surveillance camera determines the cleanliness of the mirror of the cleaned surveillance camera. If the cleanliness of the mirror does not meet the cleaning standard, step 3 is repeated until the cleanliness of the mirror meets the cleaning standard. If the cleanliness of the mirror meets the cleaning standard, the cleaning device automatically returns to the standby state, and the remaining clean water on the mirror will be evaporated by the temperature of the mirror in a short time. Step 5. If this is the last camera, the driver presses the stop cleaning button, the cleaning device returns to the storage state, and the water telescopic tube, the cleaning agent telescopic tube and the recovery device telescopic rod are retracted to the storage state; if it is not the last camera, the driver drives forward to the next camera, and then performs steps 2, 3 and 4 until the last surveillance camera is cleaned.
