Description

Technical Field

[0001] The present invention relates to the technical field of unmanned car washing platforms, and in particular to a monitoring system and method for an intelligent unmanned car washing platform. Background Art

[0002] With the continuous increase in the number of cars, intelligent car washing services have also gradually improved. Compared with the many disadvantages of traditional car washing, such as inconvenience, high cost, and difficulty in hiring workers, do-it-yourself car washing has become a development trend. In view of this situation, the intelligent unattended car washing platform has timely filled the market gap in the car washing industry, using online reservations, license plate recognition, contactless payment and other technologies, which has improved intelligence compared to do-it-yourself car washing.

[0003] However, in the field of intelligent unattended car washing platforms, there are still major defects. Compared with manual car washing, it adopts a programmed car washing method, that is, the whole car is cleaned. However, due to the different degrees of dirtiness of different parts of the car body, for example, the degree of dirtiness of the wheel hub, door edges and other parts is generally much higher than other parts. This will lead to the situation that after a programmed full-car wash, there are still stubborn stains on some parts. If the whole car is washed again, resources and material resources will be wasted. Therefore, there is a lack of accurate scanning and analysis of subsequent single-point stains. How to achieve secondary stain treatment after the full-car wash, and how to jointly treat multiple secondary stains are still problems that have not been solved by the current intelligent unattended car washing platform. Summary of the invention

[0004] The object of the present invention is to provide a monitoring system and method for an intelligent unattended car wash platform to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a monitoring method for an intelligent unattended car washing platform, the method comprising the following steps:

[0006] S1. Build an intelligent unattended car washing platform, which is connected to the user port through the Internet to achieve data communication;

[0007] S2. The intelligent unattended car washing platform is connected to the control system of the intelligent car washing machine, and outputs the license plate number of the user port to the control system. The control system of the intelligent car washing machine identifies the user's vehicle, and releases the user's vehicle after the license plate number authentication is met, and enters the intelligent car washing machine;

[0008] S3, after the user's vehicle arrives at the marked position of the smart car washing machine, the smart car washing is started. After the first comprehensive washing is completed, the recognition system is started to mark the residual stain location data of the vehicle and feed it back to the control system of the smart car washing machine;

[0009] S4. The control system of the intelligent car washing machine is connected to the car washing history database, and a residual stain analysis and processing model is constructed to integrate the residual stains to achieve secondary cleaning. After completion, the recognition system is started again until the recognition system feedback shows that there is no stain on the car body;

[0010] S5. The control system of the smart car wash machine receives the signal that the car body is free of stains from the recognition system, generates a fee list and feeds it back to the smart unattended car wash platform. After the user pays, a payment signal is generated and fed back to the control system of the smart car wash machine, and the control system releases the vehicle.

[0011] According to the above technical solution, the intelligent car washing machine includes all-round car washing and single-point car washing;

[0012] The all-round car wash refers to using a sponge to scrub the entire car body; the single-point car wash refers to using a jet water gun to clean a single point on the car body;

[0013] The water-soaked sponge and the water jet gun are both fixed on the intelligent car washing machine.

[0014] According to the above technical solution, in step S3, a full-scale car wash is used for the first full wash;

[0015] A three-dimensional space coordinate system is constructed in the internal space of the smart car washing machine, and the recognition system is started to scan the car body, mark the location of the residual stains on the vehicle, form three-dimensional coordinate data, and feed it back to the control system of the smart car washing machine;

[0016] The control system of the intelligent car washing machine is connected to the car washing history database, and calls the historical car washing monitoring data to form a data group. The specific data group includes: the distance between the water outlet of the spray water gun and the impact point of the car body, and the cleaning range radius;

[0017] The distance between the water outlet of the jet water gun and the impact point of the vehicle body refers to the distance between the coordinates of the water outlet of the jet water gun and the coordinates of the impact point of the vehicle body during any single-point car washing in the historical car washing data, and the impact point of the vehicle body refers to the contact point between the water flow and the vehicle body;

[0018] Clean the historical car wash monitoring data, including:

[0019] Selecting a water flow action area, where the water flow action area is the area of ​​a circle formed by taking the maximum distance between the coordinates of the impact point of the vehicle body and the splash point formed by the water flow on the vehicle body as the radius;

[0020] The cleaning means selecting data on uncleaned stains in the water flow action area, and selecting the minimum distance between the uncleaned stains in the water flow action area and the coordinates of the impact point of the vehicle body as the cleaning range radius;

[0021] Several data sets are formed, and each set of data is written as [D0, R0], where D0 refers to the distance between the water outlet of the water jet gun and the impact point of the vehicle body; R0 refers to the radius of the cleaning range; fitting is performed based on the several data sets to form a functional relationship between D0 and R0.

[0022] According to the above technical solution, it also includes:

[0023] Segment the current vehicle body to form a number of regions, and for any region, obtain the three-dimensional coordinate data of the position of the residual stains on the vehicle body in the region to form a regional three-dimensional coordinate data group;

[0024] The residual stains in the area are integrated, that is, there are K body impact points, each body impact point forms a cleaning range, and the three-dimensional coordinate data group of the area is within the formed cleaning range. Any cleaning range is regarded as a cluster, and the three-dimensional coordinate data of each residual stain position is taken as a sample. The K value is determined based on the elbow method:

[0025]

[0026] Among them, SSE represents the core index value of the elbow method; i represents the sequence number; K represents the total number of impact points on the vehicle body; P represents the i-th cluster C i Sample points in m i Represents the i-th cluster C i The sample mean in ;

[0027] A minimum area square is set on the vehicle body to accommodate all data in the regional three-dimensional coordinate data group, and the point in the minimum area square is selected as the initial centroid;

[0028] K centroids are randomly selected, and the distance between the centroid coordinate point and the water jet outlet is used as the distance between the water jet outlet and the impact point of the vehicle body. The cleaning range radius is formed according to the functional relationship between D0 and R0, and then the cleaning range of K clusters is formed. If the cleaning range formed by the K clusters can completely cover the regional three-dimensional coordinate data group, the coordinate data of the K centroids are written as a group and counted into the selection list; if not satisfied, reselect; until the number of coordinate data groups in the selection list reaches the set threshold;

[0029] Constructing residual stain analysis and processing model:

[0030]

[0031] Among them, Y represents the sum of distances of any cluster; j represents the sample number; e represents the total number of samples in the cluster; v j represents any sample in the cluster; v0 represents the centroid of the cluster;

[0032] Calculate the sum of Y of the K clusters, select the coordinate data of the K centroids corresponding to the smallest sum and feed them back to the control system, adjust the spray water gun to perform a second cleaning on the coordinate points of the K centroids, and then start the recognition system again until the recognition system feeds back that there is no stain on the car body.

[0033] In the above technical solution, the minimum value is used to represent that the distance of the data around the centroid is closer. In comparison, being closer to the centroid means being closer to the water flow impact point, and the cleaning effect on the remaining stains is more obvious.
