DETAILED DESCRIPTION

[0017] Reference Figure 1 As shown, an automatic washing system for a belt bridge includes: Centralized controller: The centralized controller is used to control each module and realize data transmission and information exchange between each module; A shooting module, wherein the shooting module collects images of the belt corridor to obtain a real-time image of the belt corridor, wherein the real-time image of the belt corridor specifically includes a real-time plane image of the belt corridor and a real-time side image of the belt corridor; Feature extraction module: The feature extraction module performs feature analysis on the real-time image of the belt bridge to determine the flushing position coordinates of the belt bridge and the spatial occupancy of the belt bridge; Electric ball valve, which is used to flush the belt gallery; Flow analysis module: The flow analysis module analyzes the space occupancy of the belt bridge and determines the flushing water flow rate; Flow meter, which is used to monitor the flushing water flow of the electric ball valve; Wireless sprinkler controller: The wireless sprinkler controller controls the electric ball valve to flush the belt bridge according to the flushing position coordinates of the belt bridge. The wireless sprinkler controller monitors the water flow of the electric ball valve through the flow meter to realize the switching of the electric ball valve. It will be understood by those skilled in the art that when the conveyor belt is transferring goods or debris on the belt gallery, as the conveyor belt moves, the goods or debris may fall onto the gallery and pollute the gallery. If the belt gallery is cleaned manually, it not only increases the workload of the staff, but also fails to control the water consumption. Therefore, the debris on the belt gallery is analyzed by a centralized controller to determine the flushing water flow rate. Finally, a cleaning instruction is sent to the wireless sprinkler controller through the centralized controller, and the wireless sprinkler controller controls the electric ball valve to flush the belt gallery. In addition, the flushing water flow rate of the electric ball valve is monitored by a flow meter. The above method not only reduces the workload of the staff, but also saves water.

[0018] Reference Figure 2 As shown, a belt gallery automatic flushing method, a centralized controller is used to realize data transmission and information interaction between various modules, specifically including the following steps: S101, obtaining the model of the camera module and the model of the wireless sprinkler controller; S102, the centralized controller performs data retrieval processing on the database system according to the shooting module model and the wireless sprinkler controller model, and obtains the factory manual of the shooting module and the factory manual of the wireless sprinkler controller; S103, based on the centralized controller, extracting information from the factory manual of the shooting module and the factory manual of the wireless sprinkler controller respectively, and obtaining the wireless communication protocol of the shooting module and the wireless communication protocol of the wireless sprinkler controller; S104, the centralized controller establishes communication connections with the shooting module and the wireless sprinkler controller through the wireless communication protocol of the shooting module and the wireless communication protocol of the wireless sprinkler controller respectively; In this embodiment, in order to realize the automated controlled cleaning of the belt corridor, the centralized controller establishes a communication connection with the shooting module and the wireless sprinkler controller through the wireless communication protocol of the shooting module and the wireless communication protocol of the wireless sprinkler controller to realize the real-time transmission of instructions, making the automated cleaning of the belt corridor faster and more efficient.

[0019] Reference Figure 3 As shown, the shooting module collects images of the belt corridor, and obtaining the real-time image of the belt corridor specifically includes the following steps: S201, based on the centralized controller, sending an image acquisition instruction to the shooting module; S202, based on the shooting module, shooting an image from the top of the belt gallery to obtain a real-time plane image of the belt gallery; S203, based on the shooting module, shooting an image from the side of the belt gallery to obtain a real-time side image of the belt gallery; In this embodiment, the top of the belt corridor is imaged by the shooting module in order to determine the distribution of debris on the belt corridor and determine which electric ball valve to use to clean the belt corridor subsequently, so as to achieve accurate flushing of the belt corridor. In addition, the side of the belt corridor is photographed by the shooting module in order to determine the volume of the debris and determine how much volume of water is needed to complete the flushing of the belt corridor.

[0020] Reference Figure 4 As shown, the feature extraction module performs feature analysis on the real-time image of the belt bridge, and determines the flushing position of the belt bridge and the spatial occupancy of the belt bridge, which specifically includes the following steps: S301, based on the feature extraction module, extract features from the real-time plane image of the belt gallery to determine the flushing position coordinates of the belt gallery and the contour shape of the occupied belt gallery; S302, based on the feature extraction module, extracting features from the real-time side image of the belt gallery to determine the thickness data of the occupied belt gallery; S303. Based on the centralized controller, the occupied contour shape of the belt bridge and the occupied thickness data of the belt bridge are calculated and processed to obtain the spatial occupancy of the belt bridge.

[0021] Reference Figure 5 As shown, based on the centralized controller, the occupied contour shape of the belt gallery and the occupied thickness data of the belt gallery are calculated and processed to obtain the space occupancy of the belt gallery, which specifically includes the following steps: S3031, the centralized controller constructs a function according to the contour shape of the occupied belt gallery and the thickness data of the occupied belt gallery to determine the contour similarity function; S3032, based on the centralized controller, calculating and processing according to the occupied contour shape of the belt corridor and the contour similarity function to obtain the spatial occupancy of the belt corridor; The specific calculation formula for obtaining the belt bridge space occupancy is:

[0022] In the formula, It is the space occupancy of the belt bridge; It is the boundary of the three-dimensional area enclosed by the outline shape occupied by the belt bridge; is the contour similarity function; In this embodiment, debris falls on the belt bridge. The debris may be of regular shape or irregular shape. In order to accurately determine how much water is needed for flushing, the volume of the debris needs to be calculated. However, the volume calculation of irregularly shaped debris may be more troublesome. Therefore, the volume of the debris is calculated by constructing a contour similarity function to make the subsequent water consumption analysis more accurate.

[0023] Reference Figure 6 As shown, the flow analysis module analyzes the space occupancy of the belt gallery bridge and determines the flushing water flow, which specifically includes the following steps: S401, based on the centralized controller, performing data retrieval processing on the database system to obtain historical data of flushing water flow; S402, based on the centralized controller, sending the historical data of flushing water flow to the flow analysis module; S403, the flow analysis module performs data matching processing on the historical data of the flushing water flow according to the spatial occupancy of the belt gallery bridge to obtain the flushing water flow; In this embodiment, the historical data of flushing water flow is matched with the belt corridor space occupancy. If there is no data identical to the belt corridor space occupancy in the historical data of the flushing water flow, the historical data of the flushing water flow corresponding to the data slightly larger than the belt corridor space occupancy is selected as the flushing water flow. The above data selection method is intended to avoid the problem of insufficient water flow and inability to complete flushing.

[0024] Reference Figure 7 As shown, the wireless sprinkler controller controls the electric ball valve to flush the belt gallery bridge according to the flushing position coordinates of the belt gallery bridge, and the specific steps include: S501, obtaining the installation position coordinates of the electric ball valve; S502, based on the wireless sprinkler controller, determining and processing the installation position coordinates of the electric ball valve and the flushing position coordinates of the belt gallery bridge; S503, if the installation position coordinate of the electric ball valve is less than or equal to the flushing position coordinate of the belt gallery, the electric ball valve at the upper level flushes the belt gallery; S504: If the installation position coordinate of the electric ball valve is greater than the flushing position coordinate of the belt bridge, the electric ball valve flushes the belt bridge; In this embodiment, the coordinates of the installation position of the electric ball valve and the coordinates of the flushing position of the belt corridor are compared to determine which position of the electric ball valve to use, thereby avoiding excessive use of the electric ball valve. For example, after the electric ball valve far away from debris is opened, the belt corridor cannot be cleaned and energy will be wasted. Therefore, by matching the coordinates, it is determined that the electric ball valve in the appropriate position should be used, which can not only achieve accurate cleaning of the belt corridor but also save energy.

[0025] Reference Figure 8 As shown in the figure, the wireless sprinkler controller monitors the water flow of the electric ball valve through the flow meter, which specifically includes the following steps: S601, based on the flow meter, real-time monitoring of the water flow of the electric ball valve is performed to obtain the real-time water flow; S602, based on the wireless sprinkler controller, judging and processing the real-time water flow and flushing water flow; S603, if the real-time water flow is greater than or equal to the flushing water flow, the wireless sprinkler controller closes the electric ball valve, and the electric ball valve stops flushing the belt gallery; S604: If the real-time water flow rate is less than the flushing water flow rate, the electric ball valve continues to flush the belt gallery; In this embodiment, in order to save water resources, the water flow of the electric ball valve is monitored by a flow meter to avoid using too much water to flush the belt gallery, thereby reducing the flushing cost of the belt gallery.
