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 the traditional car washing industry, such as inconvenience, high cost, and difficulty in hiring workers, self-service 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. It adopts online appointment, license plate recognition, contactless payment and other technologies, which is more intelligent than self-service car washing.

[0003] However, there are still major defects in the field of intelligent unmanned car washing platforms. Compared with manual car washing, it adopts a programmed car washing method, that is, it cleans the entire car. However, due to the different levels of dirtiness of different parts of the car body, for example, the wheel hub, door edges and other parts are generally much dirtier than other parts. This will result in stubborn stains still existing on some parts after a programmed full-car wash. 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 unmanned car washing platform. Summary of the Invention

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

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

[0006] S1. Build an intelligent unmanned car wash platform, which is connected to a user port via the Internet to achieve data communication;

[0007] S2. The intelligent unattended car wash platform connects to the control system of the intelligent car wash machine and outputs the license plate number of the user port to the control system. The control system of the intelligent car wash machine identifies the user's vehicle and allows the user's vehicle to enter the intelligent car wash machine after the license plate number is authenticated.

[0008] S3. After the user's vehicle arrives at the marked location of the smart car wash machine, the smart car wash is started. After the first comprehensive wash is completed, the recognition system is started to mark the location data of the residual stains on the vehicle and feed it back to the control system of the smart car wash 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 and implement secondary cleaning. After completion, the recognition system is restarted until the recognition system feedback indicates that there is no stain on the car body;

[0010] S5. The control system of the smart car wash machine receives the signal indicating 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 dipped in water 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 wet sponge and the water spray gun are both fixed on the intelligent car washing machine.

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

[0015] A three-dimensional coordinate system is constructed inside the intelligent car wash machine, and the recognition system is activated to scan the vehicle body, mark the location of residual stains on the vehicle, generate three-dimensional coordinate data, and feed it back to the control system of the intelligent car wash machine.

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

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

[0018] Clean 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 whose radius is the maximum distance between the coordinates of the impact point on the vehicle body and the splash point formed by the water flow on the vehicle body;

[0020] The cleaning means selecting data on uncleaned stains within the water flow action area, and selecting the minimum distance between the uncleaned stains within 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 jet water 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 several regions. For any region, obtain the three-dimensional coordinate data of the position of the residual stain on the vehicle body in the region to form a regional three-dimensional coordinate data set;

[0024] The residual stains in the area are integrated. That is, there are K body impact points, each of which forms a cleaning range. The three-dimensional coordinate data sets of the area are all within the formed cleaning range. Any cleaning range is considered a cluster. The three-dimensional coordinate data of each residual stain position is used 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] Set a minimum area square on the vehicle body that can accommodate all the data in the regional three-dimensional coordinate data set, and use the point within the minimum area square as the initial centroid selection;

[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 vehicle body impact point. 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 set, the coordinate data of the K centroids are written into a group and included in the selection list; if it does not meet the requirements, reselect until the number of coordinate data sets in the selection list reaches the set threshold;

[0029] Constructing a 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 the Y values ​​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 water jet gun to perform a second cleaning on the coordinate points of the K centroids. After completion, start the recognition system again until the recognition system feedback indicates that there is no stain on the car body.

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

After the first comprehensive cleaning is completed, the recognition system is activated to mark the residual stain positioning data of the vehicle and feed it back to the control system of the intelligent car wash machine. The secondary positioning cleaning module is used to build a residual stain analysis and processing model to integrate the residual stains to achieve secondary cleaning. After completion, the recognition system is restarted until the recognition system feeds back that the vehicle body is free of stains. The fee list monitoring module is used to generate a fee list and feed it back to the intelligent unmanned car wash platform after receiving the vehicle body free of stains signal fed back by the recognition system.

[0053] The intelligent unattended car wash platform is connected to the control system of the intelligent car wash machine, outputs the license plate number of the user port to the control system, and the control system of the intelligent car wash machine identifies the user's vehicle and releases the user's vehicle into the intelligent car wash machine after the license plate number is authenticated.

[0054] After the user's vehicle arrives at the marked position of the smart car wash machine, the smart car wash is started. The smart car wash machine includes all-round car wash and single-point car wash; the all-round car wash refers to using a wet 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;

[0055] The wet sponge and the water spray gun are both fixed on the intelligent car washing machine.

[0056] After the first comprehensive car wash, a three-dimensional coordinate system is constructed inside the intelligent car wash machine. The recognition system is activated to scan the car body, mark the location of residual stains on the vehicle, generate three-dimensional coordinate data, and feed it back to the control system of the intelligent car wash machine.

[0057] The control system of the intelligent car washing machine is connected to the car washing history database, calling the historical car washing monitoring data to form a data group. The specific data group includes: the distance between the water jet outlet and the impact point of the car body, and the cleaning range radius;

[0058] The distance between the water jet gun outlet and the impact point of the car body refers to the distance between the coordinates of the water jet gun outlet and the coordinates of the impact point of the car body during any single-point car wash in the historical car wash data. The car body impact point refers to the point of contact between the water flow and the car body.

[0059] Clean historical car wash monitoring data, including:

[0060] Selecting a water flow action area, where the water flow action area is the area of ​​a circle whose radius is the maximum distance between the coordinates of the impact point on the vehicle body and the splash point formed by the water flow on the vehicle body;

[0061] The cleaning means selecting data on uncleaned stains within the water flow action area, and selecting the minimum distance between the uncleaned stains within the water flow action area and the coordinates of the impact point of the vehicle body as the cleaning range radius;

[0062] 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 jet water 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.

[0063] Segment the current vehicle body to form several regions. For any region, obtain the three-dimensional coordinate data of the position of the residual stain on the vehicle body in the region to form a regional three-dimensional coordinate data set;

[0064] The residual stains in the area are integrated. That is, there are K body impact points, each of which forms a cleaning range. The three-dimensional coordinate data sets of the area are all within the formed cleaning range. Any cleaning range is considered a cluster. The three-dimensional coordinate data of each residual stain position is used as a sample. The K value is determined based on the elbow method:

[15] is 1. When K is less than the true number of clusters, the SSE decreases significantly because increasing K increases the degree of aggregation of each cluster. However, when K reaches the true number of clusters, the return on aggregation obtained by further increasing K rapidly decreases, so the decrease in SSE decreases sharply and then levels off as K continues to increase. In other words, the relationship between SSE and K is shaped like an elbow, and the K value corresponding to this elbow is the true number of clusters in the data, which is the K value selected in this embodiment.

[0067] Set a minimum area square on the vehicle body that can accommodate all the data in the regional three-dimensional coordinate data set, and use the point within the minimum area square as the initial centroid selection;

[0068] 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 vehicle body impact point. 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 set, the coordinate data of the K centroids are written into a group and included in the selection list; if it does not meet the requirements, reselect until the number of coordinate data sets in the selection list reaches the set threshold;

[0069] Constructing a residual stain analysis and processing model:

[0070]

[0071] 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;

Adjust the water jet gun to perform a second cleaning on the coordinate points of the K centroids. After completion, start the recognition system again until the recognition system feedback indicates that there is no stain on the car body.

[0073] The control system of the smart car wash machine receives the signal from the identification system that the car body is free of stains, 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.
