Description

Technical Field

[0001] The present application relates to the field of wiper technology, and more particularly to a wiper cleaning method, system, intelligent terminal and storage medium. Background Art

[0002] A windshield wiper, also known as a rain wiper, water wiper, water paddle or windshield wiper, is a device used to scrape off raindrops and dust attached to the windshield of a vehicle, which can improve the driver's visibility and increase driving safety.

[0003] In the related art, the wiper system usually includes two parts: an automatic system and a manual system. The automatic system is used to sense rain. When it rains, the automatic system starts the wipers to scrape the rain off the windshield to ensure safety; the manual system is controlled by personnel to control the swing speed of the wipers and actively clean the stains on the windshield.

[0004] Regarding the above-mentioned related technologies, although the automatic system can control the wipers to scrape away the rain on the windshield, it cannot sense the stains on the windshield. People need to actively control the wipers to remove the stains. When the stains are small or few, people tend to ignore the stains. When the stains accumulate to a large amount, people control the wipers to scrape away the stains. However, due to the adhesion of the accumulated stains, the wipers cannot remove all the stains, resulting in poor cleaning effect of the wipers. There is still room for improvement. Summary of the invention

[0005] In order to improve the dirt cleaning effect of a wiper, the present application provides a wiper dirt cleaning method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a wiper cleaning method, which adopts the following technical solution: A windshield wiper cleaning method, comprising: Get the start trigger information of the preset car; Acquiring image detection information of a preset windshield based on the start trigger information; Performing image analysis based on the image detection information to determine whether there is preset stain characteristic information; If there is no stain feature information, continue to obtain the image detection information of the windshield for cyclic analysis; If there is stain feature information, the wiper is controlled to scrape off the stain on the windshield according to the image detection information, and the stain removal image information is obtained in real time; Performing image analysis based on the stain removal image information to determine whether there is stain characteristic information; If there is stain feature information, the wiper is controlled to scrape off the stain on the windshield according to the image detection information, and the stain removal image information is continuously acquired for cyclic analysis; If there is no stain feature information, the wiper is controlled to reset and stop, and the image detection information of the windshield is continuously acquired for cyclic analysis.

[0007] By adopting the above technical solution, the image detection information of the windshield is analyzed to determine whether there is stain characteristic information. If so, the wiper is controlled to scrape off the stain according to the image detection information until there is no stain characteristic information in the stain removal image information, thereby preventing the accumulated stains from being difficult to clean due to the failure of personnel to clean them in time, thereby improving the cleaning effect of the wiper.

[0008] Optionally, the step of controlling a wiper to scrape off stains on the windshield according to the image detection information includes: Performing image analysis based on the image detection information to determine that the stain is a preset local stain characteristic information or a preset comprehensive stain characteristic information; If it is local stain feature information, the wiper is controlled to scrape off the stain on the windshield according to a preset local scraping method; If it is comprehensive stain feature information, image analysis is performed based on the image detection information to determine the stain area information; Determine the swing speed information according to the stain area information and the preset first area-speed relationship information, and determine the dewatered water volume information according to the stain area information and the preset first area-water volume relationship information; The wipers and the preset water spray device are controlled according to the swing speed information and the amount of dirty water removed to scrape off the stains on the windshield.

[0009] By adopting the above technical solution, after performing image analysis based on the image detection information, it is determined that the stain is local stain characteristic information or comprehensive stain characteristic information, so that according to the different types of stains, the wiper is controlled to remove stains in different working modes, thereby improving the cleaning effect of the wiper.

[0010] Optionally, the step of controlling the wiper and the preset water spray device to scrape off the stains on the windshield according to the swing speed information and the water removal amount information includes: Controlling the water spraying device to spray the decontaminated water onto the windshield with a water volume corresponding to the decontaminated water volume information, and obtaining spraying completion trigger information; According to the spray completion trigger information, the wiper is controlled to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, and a swing trigger information is obtained; According to the one-time swing trigger information, the water spray device is controlled to spray the decontaminated water onto the windshield again with the amount of water corresponding to the decontaminated water amount information, and the spray completion trigger information is updated; According to the updated spray completion trigger information, the wiper is controlled again to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, and the swing trigger information is updated once.

[0011] By adopting the above technical solution, before the wiper swings once, the water spray device is controlled to spray water once, thereby reducing the friction between the wiper and the windshield, preventing the wiper from scratching the windshield, and thus improving the protection of the windshield during the cleaning process, and spraying water before the wiper scrapes off the stains, effectively improving the dirt removal effect of the wiper.

[0012] Optionally, the step of controlling the wiper to scrape off the stains on the windshield according to a preset local scraping method includes: If it is local stain feature information, then the stain location information is determined by analyzing the image detection information and a preset coordinate system; Determine the wiper start sequence information according to the stain position information and the preset position sequence relationship information; The wipers are controlled to scrape away the stains on the windshield according to the stain position information and the wiper start sequence number information.

[0013] By adopting the above technical solution, when the stain is a local stain characteristic information, the stain location information is determined, and then the wiper for scraping off this type of stain is determined according to the stain location information, so that only one wiper needs to be mobilized to complete the removal of the stain, and there is no need to swing the other wiper that is not doing the cleaning work. While ensuring the cleaning effect, the energy consumption and wear on the wiper are reduced.

[0014] Optionally, the step of controlling the wiper to scrape off the stains on the windshield according to the stain position information and the wiper start sequence information includes: Analyze the stain location information and the corresponding wiper start sequence number information to determine the location information of the same area; Analyze the same area position information and preset wiper fixed point position information to determine the swing angle information; Obtaining local stain area information at a position corresponding to the same regional position information; Determine local speed information according to the local stain area information and preset second area-speed relationship information; According to the swing angle information, local speed information and the start-up wiper sequence information, the wiper is controlled to swing and spray dirty water to remove stains on the windshield.

[0015] By adopting the above technical scheme, the swing angle information of the wiper is determined according to the position information of the same area and the fixed-point position information of the wiper, so that the wiper only swings at the angle corresponding to the swing angle information, and will not swing to a range where no stains exist. At the same time, during the swinging process, the wiper is controlled to spray water so that the position of the water spraying is always consistent with the scraping position, thereby improving the dirt removal effect of the wiper.

[0016] Optionally, the step of controlling the wiper to swing and spraying the waste water to remove the stains on the windshield according to the swing angle information, the local speed information and the start-up wiper sequence information includes: Call the location information of the same area one by one to determine the spraying location information; Determine the spray angle information according to the spray position information and the preset position angle relationship information, and determine the spray sequence number information according to the spray position information and the preset spray position relationship information; Get the spray area information of the spray position information; Determine the local water volume information according to the spray area information and the preset second area water volume relationship information; Control the wiper swing according to the swing angle information, the local speed information and the wiper start sequence number information, and obtain the swing angle detection information in real time; When the swing angle detection information is equal to the spray angle information, the preset water spray port on the wiper is controlled to spray the windshield with decontaminated water according to the corresponding spray sequence number information and the local water volume information.

[0017] By adopting the above technical scheme, the spray angle information of the wiper when spraying at that position is first determined according to the spray position information, and then the spray sequence number information of the water outlet on the wiper that sprays at that position is determined. Therefore, when the swing angle detection information of the wiper is equal to the spray angle information, the water outlet corresponding to the spray sequence number information is controlled to spray water on the windshield with the water volume corresponding to the local water volume information, thereby improving the accuracy of the wastewater spraying.

[0018] Optionally, when controlling the wiper to scrape off the stains on the windshield according to the image detection information, a monitoring step of the wiper is also included, and the specific steps include: When controlling the wiper to scrape off the stains on the windshield according to the image detection information, obtaining the decontamination efficiency information of the wiper; Determine whether the decontamination efficiency information meets the requirements of the preset normal efficiency information; If it meets the requirements, the wiper is controlled to scrape the stains on the windshield according to the image detection information; If not, the personnel will be prompted to replace the wipers and clean the inside of the windshield according to the preset wiper replacement reminder information and the preset interior cleaning reminder information.

[0019] By adopting the above technical solution, when the wiper's dirt removal efficiency information is lower than the normal efficiency information, personnel are reminded of the aging of the wiper based on the wiper replacement reminder information and the internal cleaning reminder information. At the same time, the inside of the windshield is cleaned to prevent efficiency misjudgment due to stains inside the windshield, thereby improving the monitoring effect of the wiper.

[0020] In a second aspect, the present application provides a wiper cleaning system, which adopts the following technical solution: A windshield wiper cleaning system, comprising: An acquisition module, used to acquire start trigger information, image detection information and stain removal image information; A memory for storing a program of a wiper cleaning method as described in any one of the above items; The program in the processor memory can be loaded and executed by the processor to implement a wiper cleaning method as described in any one of the above items.

[0021] By adopting the above technical solution, the processor loads and executes a program of a wiper cleaning method stored in the memory, thereby controlling the acquisition module to obtain a series of data related to wiper cleaning. When it is determined through image recognition that there are stains on the windshield, the wiper is controlled to clean automatically, thereby preventing the accumulated stains from being difficult to clean due to the failure of personnel to clean the stains in time, thereby improving the cleaning effect of the wiper.

[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a wiper cleaning method as described in any one of the above items.

[0023] By adopting the above technical solution and operating the intelligent terminal, the processor is made to load and execute a computer program of a wiper cleaning method stored in the memory, so that when it is determined by image recognition that there are stains on the windshield, the wiper is controlled to clean automatically, thereby preventing the accumulated stains from being difficult to clean due to the failure of personnel to clean the stains in time, thereby improving the cleaning effect of the wiper.

[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the characteristic of facilitating improving the cleaning effect of a windshield wiper, and adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned wiper cleaning methods.

[0025] By adopting the above technical solution, a computer program of a wiper cleaning method is stored in a computer-readable storage medium, so that the processor loads and executes the computer program stored in the storage medium, and when it is determined by image recognition that there are stains on the windshield, the wiper is controlled to automatically clean it, thereby preventing the accumulated stains from being difficult to clean due to the failure of personnel to clean the stains in time, thereby improving the cleaning effect of the wiper.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By analyzing the image detection information of the windshield, it is determined whether there is stain feature information.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a method for automatically removing stains from a wiper, and specifically discloses a processing terminal, an image acquisition device and a wiper. The processing terminal is respectively connected to the image acquisition device and the wiper through data wires to realize data interaction and control. When the processing terminal receives the start trigger information of the car, the processing terminal controls the image acquisition device to acquire image detection information of the windshield and sends it to the processing terminal. The processing terminal performs image analysis on the image detection information to determine whether there is stain feature information. When the stain feature information exists, the processing terminal controls the wiper to scrape off the stains on the windshield according to the image detection information, and controls the image acquisition device to acquire stain removal image information in real time until the stain removal image information does not contain the stain feature information and stops, thereby preventing the accumulated stains from being difficult to clean due to the failure of personnel to clean the stains in time, thereby improving the cleaning effect of the wiper.

[0036] Reference Figure 1 The present application discloses a method for cleaning dirt on a wiper blade, comprising the following steps: Step S100: obtaining the start trigger information of a preset car.

[0037] The start trigger information refers to the trigger data for starting the vehicle, which is obtained by the vehicle system sending the start data to the processing terminal.

[0038] Step S101: acquiring image detection information of a preset windshield based on the start trigger information.

[0039] Among them, when the processing terminal obtains the start trigger information, it indicates that the person needs to use the car, because the windshield needs to be cleaned before use to prevent stains from affecting the person's line of sight, so the image detection information of the windshield is collected to provide data support for the subsequent determination of whether the windshield needs to be cleaned.

[0040] The windshield refers to the windshield on the car. The image detection information refers to the image of the windshield, which is captured by a camera installed in the car and sent to the processing terminal.

[0041] Step S102: performing image analysis based on the image detection information to determine whether there is preset stain feature information.

[0042] The stain feature information refers to the stain feature in the image. The operator uses different types of stains as training samples for the image recognition model to train and learn. The image corresponding to the image detection information is used as input by the processing terminal, so that the trained image recognition model can perform image recognition on the image corresponding to the image detection information, thereby determining whether the stain feature corresponding to the stain feature information exists in the image corresponding to the image detection information, and providing data support for the subsequent determination of whether the windshield needs to be cleaned.

[0043] Step S1021: If there is no stain feature information, continue to obtain the image detection information of the windshield for cyclic analysis.

[0044] Among them, if the processing terminal determines that the stain feature corresponding to the stain feature information does not exist in the image corresponding to the image detection information, it indicates that there is no stain on the windshield, so there is no need to control the wiper to scrape off the stain on the windshield, so as to continue to collect image detection information of the windshield to continuously monitor the stain situation on the windshield.

[0045] Step S1022: If there is stain feature information, the wiper is controlled to scrape off the stain on the windshield according to the image detection information, and the stain removal image information is obtained in real time.

[0046] If the processing terminal determines that the stain feature corresponding to the stain feature information exists in the image corresponding to the image detection information, it indicates that there is stain on the windshield, so it is necessary to control the wiper to scrape off the stain on the windshield, thereby controlling the wiper to scrape off the stain on the windshield according to the image detection information. The specific method is referred to Figure 2 The steps are performed and the stain removal image information is detected to provide data support for the subsequent control of the wiper to stop.

[0047] The stain removal image information refers to the image of the windshield during the stain removal process, which is captured by a camera installed inside the car and sent to a processing terminal.

[0048] Step S103: performing image analysis based on the stain removal image information to determine whether stain feature information exists.

[0049] Among them, after the processing terminal obtains the stain removal image information, the image corresponding to the stain removal image information is used as input for recognition by the trained image recognition model, so as to determine whether there is a stain feature corresponding to the stain feature information in the image corresponding to the stain removal image information, thereby providing data support for the subsequent control of the wiper to stop.

[0050] Step S1031: If there is stain feature information, continue to control the wiper to scrape off the stains on the windshield according to the image detection information, and continue to obtain stain removal image information for cyclic analysis.

[0051] Among them, if the processing terminal determines that there is a stain feature corresponding to the stain feature information in the image corresponding to the stain removal image information, it means that the wiper has not yet removed all the stains. Therefore, the wiper continues to be controlled to scrape off the stains on the windshield according to the image detection information, and continues to obtain the stain removal image information to continue to pay attention to the stain removal situation of the wiper.

[0052] Step S1032: If there is no stain feature information, the wiper is controlled to reset and stop, and the image detection information of the windshield is continuously acquired for cyclic analysis.

[0053] Among them, if the processing terminal determines that the stain feature corresponding to the stain feature information does not exist in the image corresponding to the stain removal image information, it means that the wiper has removed all the stains. Therefore, the wiper is controlled to reset and stop, and the image detection information of the windshield continues to be collected, so as to continue to pay attention to the stain situation on the windshield.

[0054] Reference Figure 2 The steps of controlling the wiper to scrape off the stains on the windshield according to the image detection information include: Step S200: performing image analysis according to the image detection information to determine whether the stain is a preset local stain characteristic information or a preset comprehensive stain characteristic information.

[0055] Among them, local stain feature information refers to stains that occupy a small part of the windshield, such as stains that exist only within the swing range of one wiper, or stains that are close to each other within the swing range of two wipers and cover a small range along the swing direction. The specific distance and range can be determined by the operator according to actual conditions. Comprehensive stain feature information refers to stains that occupy most of the windshield, exist within the swing range of both wipers, and cover a large range along the swing direction.

[0056] The image corresponding to the image detection information is taken as input by the processing terminal for recognition by the trained image recognition model, so as to determine whether the stain in the image corresponding to the image detection information is the stain corresponding to the local stain feature information or the stain corresponding to the comprehensive stain feature information, thereby providing data support for the subsequent determination of how to control the wiper to remove dirt.

[0057] Step S201: If it is local stain feature information, the wiper is controlled to scrape off the stain on the windshield according to a preset local scraping method.

[0058] If the processing terminal determines that the stain in the image corresponding to the image detection information is the stain corresponding to the local stain feature information, it means that the stain only occupies a small part of the windshield. If a comprehensive cleaning method is used, it will not only waste energy but also cause wear to the wiper. Therefore, the wiper is controlled to scrape the stain on the windshield according to the local scraping method. The specific method is referred to Figure 4 steps.

[0059] Step S202: If it is comprehensive stain feature information, image analysis is performed based on the image detection information to determine the stain area information.

[0060] Among them, if the processing terminal determines that the stains in the image corresponding to the image detection information are the stains corresponding to the comprehensive stain feature information, it means that the stains occupies most of the position on the windshield. Therefore, it is necessary to adopt a comprehensive dirt cleaning method to determine the stain area information based on the image detection information to provide data support for subsequent control of wiper cleaning.

[0061] The stain area information refers to the stain area on the windshield. The processing terminal divides the image corresponding to the image acquisition information into a number of preset grids to determine the number of grids occupied by the stain, and then multiplies it by the area represented by each grid to obtain the stain area information.

[0062] Step S203: determining the swing speed information according to the stain area information and the preset first area-speed relationship information, and determining the dewatered water volume information according to the stain area information and the preset first area-water volume relationship information.

[0063] Among them, the first area-speed relationship information refers to a database storing the corresponding relationship between the swing speed and the stain area, and the two are proportional, that is, the larger the stain area, the faster the wiper swings, so as to achieve the effect of rapid decontamination. The proportional coefficient between the two is determined by the operator according to the actual situation, and the two are stored in the database after one-to-one correspondence to form the first area-speed relationship information. The first area-water relationship information refers to a database storing the corresponding relationship between the spray water volume and the stain area, and the two are proportional, that is, the larger the stain area, the more water volume is required to spray for decontamination. The proportional coefficient between the two is determined by the operator according to the actual situation, and the two are stored in the database after one-to-one correspondence to form the first area-water relationship information.

[0064] The swing speed information refers to the swing speed of the wiper when performing comprehensive decontamination, and is obtained by the processing terminal inputting the area corresponding to the stain area information into the database corresponding to the first area-speed relationship information and matching the output. The decontamination volume information refers to the volume of decontamination water sprayed when the wiper performs comprehensive decontamination, and is obtained by the processing terminal inputting the area corresponding to the stain area information into the database corresponding to the first area-water volume relationship information and matching the output.

[0065] Step S204: Control the wiper and the preset water spray device to scrape off the stains on the windshield according to the swing speed information and the sewage removal amount information.

[0066] Among them, after the processing terminal obtains the swing speed information and the amount of decontamination, the wiper is controlled to swing at a speed corresponding to the swing speed information to fully decontaminate, and the water spray device is controlled to spray the decontamination with a water volume corresponding to the amount of decontamination information. The specific method is referred to Figure 3 The water spray device is a device used to spray the decontaminated water during comprehensive decontamination. It is located at the lower end of the windshield and includes a water storage tank, a water pump and a water pipe. The water pump sprays the decontaminated water in the water storage tank to the windshield through the water pipe.

[0067] Reference Figure 3 The steps of controlling the wiper and the preset water spray device to scrape the stains on the windshield according to the swing speed information and the water removal amount information include: Step S300: Control the water spraying device to spray the decontaminated water onto the windshield with a water volume corresponding to the decontaminated water volume information, and obtain spraying completion trigger information.

[0068] Among them, the water spraying device is controlled to first spray the decontaminated water onto the windshield with the amount of water corresponding to the decontaminated water amount information, thereby lubricating the windshield, making the environment on the windshield more suitable for the wiper to scrape off stains, and detecting the spray completion trigger information to provide data support for the subsequent control of the wiper swing.

[0069] The spray completion trigger information refers to the trigger data for completion of the spraying of sewage. After the spraying device completes the spraying, the spray completion trigger information is transmitted to the processing terminal for acquisition.

[0070] Step S301: according to the spray completion trigger information, the wiper is controlled to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, and a swing trigger information is obtained.

[0071] Among them, after the processing terminal obtains the spray completion trigger information, the processing terminal controls the wiper to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, thereby reducing the wear of the wiper while ensuring the wiper's decontamination effect, and detects the swing trigger information once to provide data support for the subsequent control of the water spray device to spray again.

[0072] One swing trigger information refers to trigger data when the wiper completes one swing, which is sensed by the sensing device and sent to the processing terminal when the wiper swings once.

[0073] Step S302: according to the one-time swing trigger information, the water spraying device is controlled to spray the decontaminated water onto the windshield again with the amount of water corresponding to the decontaminated water amount information, and the spraying completion trigger information is updated.

[0074] Among them, after the processing terminal receives a swing trigger information, it indicates that the wiper has completed a swing, and the dirty water on the windshield is scraped away by the wiper. Therefore, the water spray device is controlled again to spray the dirty water on the windshield with the amount of water corresponding to the dirty water amount information, so that the wiper is lubricated and decontaminated again before the swing, and the spray completion trigger information is updated so that the wiper can continue to swing once after the spraying is completed.

[0075] Step S303: According to the updated spray completion trigger information, the wiper is controlled again to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, and the swing trigger information is updated once.

[0076] Among them, after the processing terminal receives the updated spray completion trigger information, it controls the wiper again to swing at a speed corresponding to the swing speed information to scrape off the stains on the windshield, and updates the swing trigger information once, so that the water spray device and the wiper can remove the stains on the windshield in the cycle of intermittent spraying and swinging.

[0077] Reference Figure 4 The step of controlling the wiper to scrape off the stains on the windshield according to the preset local scraping method includes: Step S400: If it is local stain feature information, then analyze according to the image detection information and a preset coordinate system to determine the stain location information.

[0078] Among them, when it is determined that the stains on the windshield are features corresponding to local stain feature information, the processing terminal maps the coordinate system to the image corresponding to the image detection information, thereby identifying the stain location information and providing data support for subsequent control of the wiper to scrape off the stains.

[0079] The stain position information refers to the position coordinates of the stain on the windshield. The processing terminal maps the coordinate system to the image corresponding to the image detection information, and then identifies the coordinates corresponding to the stain features to obtain the stain position.

[0080] Step S401: determining the wiper start sequence information according to the stain position information and preset position sequence relationship information.

[0081] Among them, the position sequence number relationship information refers to a database that stores the corresponding relationship between the stain position and the wiper start-up sequence number. The two wipers are respectively assigned a sequence number, for example, No. 1 and No. 2. The two wipers respectively control the stain removal work in an area on the windshield. The operator stores all the position information in the corresponding area in the database in correspondence with the wiper sequence number, thereby forming the position sequence number relationship information.

[0082] The wiper start sequence number information refers to the sequence number of the wiper that needs to be started, and is obtained by the processing terminal inputting the position corresponding to the stain position information into the database corresponding to the position sequence number relationship information and matching the output.

[0083] Step S402: Controlling the wipers to scrape off the stains on the windshield according to the stain position information and the wiper start sequence number information.

[0084] After the processing terminal obtains the start-up wiper sequence number information, the corresponding wiper is controlled to start according to the start-up wiper sequence number information, so as to scrape off the stain at the position corresponding to the stain position information. The specific method is as follows: Figure 5 steps.

[0085] Reference Figure 5 The step of controlling the wiper to scrape off the stains on the windshield according to the stain position information and the wiper start sequence information includes: Step S500: Analyze the stain location information and the corresponding wiper start sequence information to determine the same area location information.

[0086] The same-area position information refers to all the stain positions in the same area, and the processing terminal classifies the positions corresponding to the stain position information with the same serial number as the wiper startup serial number information into one category.

[0087] Step S501: Analyze the same area position information and preset wiper fixed point position information to determine the swing angle information.

[0088] The fixed-point position information of the wiper refers to the position coordinates of the fixed end point of the wiper, including two position coordinates, which are the end point coordinates of the two wipers, and are stored in the processing terminal by the operator. The swing angle information refers to the angle value of the wiper swing. The processing terminal first selects the fixed-point position information of the wiper corresponding to the area corresponding to the same area position information, and then connects the coordinates corresponding to the same area position information with the coordinates corresponding to the fixed-point position information of the wiper, and calculates the angle between the connecting line and the coordinate axis according to the Pythagorean theorem, so that the angle range between the minimum angle and the maximum angle is the swing angle information.

[0089] Step S502: obtaining local stain area information at a position corresponding to the same regional position information.

[0090] The local stain area information refers to the area value of all stains in an area. The method for obtaining the local stain area is consistent with the method for obtaining the comprehensive stain area information in step S202, and will not be described in detail here.

[0091] Step S503: determining local speed information according to the local stain area information and preset second area-speed relationship information.

[0092] The second area-speed relationship information in this step is consistent with the first area-speed relationship information in step S203, and will not be described in detail here. The local speed information refers to the speed value of the corresponding wiper swinging in the area, and the processing terminal inputs the area corresponding to the local stain area information into the database corresponding to the second area-speed relationship information and matches the output.

[0093] Step S504: Control the wipers to swing and spray the waste water to remove stains on the windshield according to the swing angle information, the local speed information and the wiper start sequence number information.

[0094] After the processing terminal obtains the local speed information, the wiper is started according to the sequence number corresponding to the start wiper sequence number information, and the wiper is controlled to swing at the angle corresponding to the swing angle information and the speed corresponding to the local speed information, while spraying to remove the sewage. The specific method is referred to Figure 6 Steps to accurately remove stains on the windshield.

[0095] Reference Figure 6 The steps of controlling the wiper to swing and spraying the waste water to remove the stains on the windshield according to the swing angle information, the local speed information and the start-up wiper sequence number information include: Step S600: The location information of the same area is called one by one to determine the spraying location information.

[0096] The spraying position information refers to the position in the same area where spraying is required to remove sewage. In fact, it is each stain position corresponding to the position information of the same area, which is obtained by calling one by one by the processing terminal.

[0097] Step S601: determining the spray angle information according to the spray position information and the preset position angle relationship information, and determining the spray sequence number information according to the spray position information and the preset spray position relationship information.

[0098] Among them, the position angle relationship information refers to a database storing the corresponding relationship between the spray position and the swing angle. When the wiper swings to different angles, the wiper covers different position coordinates. The operator matches the angle with the covered position coordinates and stores them in the database, thereby forming the position angle relationship information. The spray position relationship information refers to a database storing the corresponding relationship between the water outlet serial number and the spray position. When the wiper swings to a certain angle to cover the spray position, different covered positions correspond to different water outlets on the wiper. Therefore, the operator matches the spray position with the water outlet serial number and stores them in the database, thereby forming the spray position relationship information.

[0099] The spray angle information refers to the angle of the wiper when the water outlet in the wiper sprays to remove sewage, and is obtained by the processing terminal inputting the position corresponding to the spray position information into the database corresponding to the position angle relationship information and matching the output. The spray sequence number information refers to the sequence number of the water outlet that sprays the spray position, and is obtained by the processing terminal inputting the position corresponding to the spray position information into the database corresponding to the spray position relationship information and matching the output.

[0100] Step S602: Acquire the spraying area information of the spraying position information.

[0101] The spray area information refers to the stain area at the spray position. The spray area information is actually the stain area at each local stain position. The acquisition method is the same as the local stain area information in step S502, and will not be repeated here.

[0102] Step S603: determining local water volume information according to the spraying area information and the preset second area-water volume relationship information.

[0103] The second area water volume relationship information in this step is consistent with the first area water volume information in step S203, and will not be described in detail here. The local water volume information refers to the amount of decontaminated water sprayed on a specific stain, and the processing terminal inputs the area corresponding to the spray area information into the database corresponding to the second area water volume relationship information to match the output spray water volume.

[0104] Step S604: Control the wiper to swing according to the swing angle information, the local speed information and the wiper start sequence number information, and obtain the swing angle detection information in real time.

[0105] Among them, after determining the local water volume information, the processing terminal controls the start of the wiper according to the serial number corresponding to the wiper start number information, and swings back and forth at the speed corresponding to the local speed information within the angle range corresponding to the corresponding swing angle information, and detects the swing angle information to provide data support for the subsequent control of the water outlet to spray and remove sewage.

[0106] The swing angle detection information refers to the angle value of the wiper swing. The processing terminal identifies the rotation angle of the motor that controls the wiper swing, and multiplies the rotation angle by the proportionality coefficient between the rotation angle and the swing angle to calculate the swing angle.

[0107] Step S605: When the swing angle detection information is equal to the spray angle information, the preset water spraying ports on the wiper are controlled to spray the decontaminated water onto the windshield according to the corresponding spray sequence number information and the local water volume information.

[0108] Among them, when the processing terminal determines that the angle corresponding to the swing angle detection information is equal to the angle corresponding to the spray angle information, it indicates that the wiper covers the position corresponding to the spray position information, thereby starting the corresponding water outlet according to the corresponding spray sequence number information, and controlling the water outlet to spray the decontamination water with the water volume corresponding to the local water volume information, thereby spraying the decontamination water while the wiper scrapes off the stains, thereby ensuring the decontamination effect of the wiper.

[0109] The water spray port refers to the water outlet evenly opened on the wiper, the water outlet is connected to the water pipe, and the water pump transports the clean water to the water outlet through the water pipe, thereby spraying the clean water out.

[0110] Reference Figure 7 When controlling the wiper to scrape off the stains on the windshield according to the image detection information, it also includes a monitoring step of the wiper, and the specific steps include: Step S700: When controlling the wiper to scrape off the stains on the windshield according to the image detection information, the dirt removal efficiency information of the wiper is obtained.

[0111] Among them, when the processing terminal controls the wiper to scrape off the stains on the windshield according to the image detection information, the dirt removal efficiency information of the wiper is detected to provide data support for the subsequent determination of whether the wiper is aged.

[0112] The dirt removal efficiency information refers to the dirt removal efficiency of the wiper. The area difference of the stains is detected at a certain interval, and the dirt removal efficiency is obtained by calculating the quotient of the area difference and the interval time.

[0113] Step S701: Determine whether the decontamination efficiency information meets the preset normal efficiency information requirements.

[0114] Among them, the normal efficiency information refers to the normal dirt removal efficiency of the wiper. The specific value is determined by the operator according to the actual situation. The requirement of the normal efficiency information refers to the efficiency not less than that corresponding to the normal efficiency information, which is stored in the database by the operator.

[0115] Whether the efficiency corresponding to the decontamination efficiency information is not less than the efficiency corresponding to the normal efficiency information is determined by the processing terminal, thereby determining whether the decontamination effect of the wiper is good.

[0116] Step S7011: If it meets the requirements, continue to control the wipers to scrape off the stains on the windshield according to the image detection information.

[0117] Among them, if the processing terminal determines that the efficiency corresponding to the dirt removal efficiency information is not less than the efficiency corresponding to the normal efficiency information, it indicates that the dirt removal effect of the wiper is good and the wiper is not aged, so continue to control the wiper to scrape off the stains on the windshield according to the image detection information.

[0118] Step S7012: If not, the personnel are prompted to replace the wipers and clean the inside of the windshield according to the preset wiper replacement prompt information and the preset internal cleaning prompt information.

[0119] Among them, if the processing terminal determines that the efficiency corresponding to the dirt removal efficiency information is less than the efficiency corresponding to the normal efficiency information, it means that the dirt removal effect of the wiper is poor, the wiper has aged, or there are stains inside the windshield, resulting in efficiency calculation errors. Therefore, according to the wiper replacement prompt information and the internal cleaning prompt information, the personnel are prompted to replace the wiper and clean the inside of the windshield, so as to ensure the dirt removal effect of the wiper.

[0120] The wiper replacement reminder information refers to the information that reminds the personnel to replace the wipers, and the internal cleaning reminder information refers to the information that reminds the personnel to clean the inside of the windshield. Both of them can be in the form of voice and text, and stored in the processing terminal by the operator.
