[0023] The present application provides a water storage tank segmented spray washing control method and system, which solves the technical problems in the prior art that the spray washing system lacks multi-layer structure adaptability, intelligent sensing capability and dynamic control strategy, resulting in low cleaning efficiency, serious water resource waste and insufficient cleaning precision, further affecting the automatic operation and maintenance level, cleaning quality and overall energy efficiency management of the water storage equipment. The technical target of layered accurate spray washing control of the water storage tank based on the reduced dirt map is achieved, and the technical effects of improving the cleaning coverage, reducing water and energy consumption, enhancing the system response flexibility and self-adaptive adjustment capability are achieved.

[0024] The technical solutions in the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described here. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. In addition, it should be noted that only parts related to the present application are shown in the drawings for convenience of description, not all.

[0025] Embodiment one, please refer to the drawingsFigure 1 The application provides a water storage tank segmented spray washing control method, which is applied to a water storage tank segmented spray washing control system and specifically includes the following steps: S1: Perform water storage tank four-section spray washing deployment, develop four-layer control units and embed them in an intelligent control system, wherein each layer control unit takes a high-pressure pump station and a layered electromagnetic valve group as a control component and takes a rotary spray head matrix as an execution component.

[0026] Specifically, the water storage tank four-section spray washing deployment refers to dividing the internal space of the entire water storage tank into four independent spray washing areas in the height dimension, which correspond to the top layer of the water storage tank, the middle layer of the water storage tank, the lower layer of the water storage tank and the bottom layer of the water storage tank, so as to facilitate the development of differentiated control strategies according to the dirt types and cleaning difficulties of different areas. Each area is independently provided with corresponding cleaning equipment, four-layer control units are developed, four independent control modules are designed and implemented, each control module is responsible for coordinating the spray washing operation of the layer, so as to achieve a spray washing effect of local optimization and overall coordination, thereby improving the comprehensiveness and efficiency of cleaning. Each layer control unit contains integrated control logic of a series of parameters such as spray head action, valve opening and closing, water pressure adjustment and spray washing path optimization, and has intelligent and adaptive capabilities. Each control unit can sense the working state of the equipment in the area and adjust according to preset rules or real-time feedback, so as to achieve more accurate spray washing scheduling. Embedding the intelligent control system means that the four-layer control units are unified into a central control system with intelligent algorithms and decision-making capabilities. The intelligent control system has functions such as information collection, data processing, strategy generation and signal scheduling, and can realize linkage, complementation and coordination between multiple layer control units. The intelligent control system can not only optimize the spray washing strategy according to the information returned by the sensor, but also store historical cleaning data to realize self-learning and optimization of the control strategy.

[0027] Each layer control unit takes a high-pressure pump station and a layered electromagnetic valve group as a control component, which illustrates the key hardware basis of spray washing control. The high-pressure pump station is the core equipment for providing strong water flow power and can continuously output water flow within a certain pressure range to adapt to the needs of different spray washing intensities; the layered electromagnetic valve group is an electrically controlled valve installed on each layer of water pipeline and is responsible for controlling the on-off and flow direction of water flow, thereby realizing independent control of each spray head. These two components together constitute the hardware basis of spray washing execution action and determine the path, intensity and scheduling frequency of water flow. Taking a rotary spray head matrix as an execution component means that multiple rotary spray heads are installed on each layer, the rotary spray heads are arranged in an array according to certain rules and can rotate in the specified area, thereby expanding the cleaning coverage. The rotary spray head has stronger adaptability than the fixed spray head and can perform multi-angle spray washing on complex structure surfaces to improve the spray washing efficiency. The spray head matrix emphasizes the spatial layout of the spray heads, and reasonable arrangement of the spray heads can avoid repeated spray washing and blind spots, thereby achieving uniform coverage while saving water.

[0028] S2: Connect the scanning imaging device, perform global scanning on the spray cleaning target, and return to the intelligent control system to trigger the data processing engine to perform dimension reduction conversion guided by spray cleaning control, and determine the reduced-order dirt map.

[0029] Specifically, connecting the scanning imaging device refers to connecting a type of hardware device used for image acquisition with the entire water tank spray cleaning system, which can obtain image data of the surface to be cleaned in different spectral or spatial dimensions. The scanning imaging device is the basis of the entire data acquisition link, and its connection not only involves physical wiring, but also includes data protocol docking and sensor synchronization, so that it can operate cooperatively with the control system to ensure that the scanning data is transmitted to the subsequent processing link in real time and completely.

[0030] Subsequently, performing global scanning on the spray cleaning target means using the imaging device to cover the surface state of each area inside the water tank. The meaning of global is that there are no dead angles in the spatial dimension, including the top, middle, lower and bottom, and also including various detail sites such as dead angles, gaps and corners. The spray cleaning target is the surface area inside the water tank that may have dirt, and the result of global scanning is to obtain a complete, three-dimensional digital image data set, which provides the original basis for dirt identification and cleaning strategy formulation.

[0031] Then, returning to the intelligent control system means transmitting the obtained image data to the central processing module of the system through a data link or wireless communication method. The intelligent control system is the brain of the entire cleaning device, which has the ability of perception, analysis, judgment and control, can call built-in algorithms for rapid processing after receiving image information, and dispatch actuators for response according to the target situation. The timeliness and stability of data return directly affect the response speed and processing efficiency of the system.

[0032] Then, triggering the data processing engine to perform dimension reduction conversion guided by spray cleaning control means that as soon as the intelligent control system receives the scanning data, the internal data processing engine automatically starts to convert the original image information into a simplified model more suitable for control, forming a compressed data expression. The data processing engine is an operation module specially used for tasks such as data cleaning, feature selection and dimension reduction algorithm, which may integrate machine learning models and image recognition algorithms.

[0033] Finally, determining the reduced-order dirt map means that after dimension reduction conversion, a low-dimensional but high-expression data model is generated, called reduced-order dirt map, which retains the main dirt features affecting the spray cleaning decision and displays key information such as dirt intensity, coverage range and cleaning difficulty level of each area in a structured form. The reduced-order dirt map will become an important input parameter for subsequent spray cleaning path planning, spray head angle adjustment, pressure regulation and other control strategy formulation.

[0034] S3: For the reduced rank dirt map, introduce the four-layer control unit, execute the timing cycle of four-layer same drive spray decision and interlayer timing logic integration, determine the whole machine control strategy and write into the register, and perform directional control management of distributed components through the intelligent control system.

[0035] Specifically, for the reduced rank dirt map, the four-layer control unit is introduced, which means that the dirt distribution data that has been processed by dimension reduction, i.e. the reduced rank dirt map, is injected as an input signal into the four spray control layers inside the system. The reduced rank dirt map is a dirt information model after data compression and structure extraction, which retains the key pollution area position, density and type, and discards redundant information. The four-layer control unit corresponds to the spray modules of the top, middle, lower and bottom layers of the water storage tank, and each layer has an independent execution and response mechanism. The purpose of introducing the map is to allow each control layer to respond to the dirt target in layers, thereby achieving directional precision cleaning.

[0036] Executing the timing cycle of four-layer same drive spray decision and interlayer timing logic integration means that the four-layer control unit simultaneously starts the periodic spray action with a time rhythm according to the received dirt map. Same drive means that each layer operates under the same time reference, avoiding conflicts or resource overlaps between upper and lower layers. The spray decision of each layer has independence, such as the spiral pulse mode for the top layer and the ladder staggered mode for the middle layer, which are formulated based on their own device characteristics and map guidance. At the same time, the timing logic integration between layers is performed, i.e. the sequence and synchronization logic of each layer in time are coordinated to ensure that water pressure, electrical control and mechanical action do not interfere with each other.

[0037] Determining the whole machine control strategy and writing it into the register means that the integrated control instructions of each layer are unified into a complete system strategy, and are written into the register of the control system in the form of digital signals. The whole machine control strategy includes spray head start sequence, water pressure adjustment parameters, electromagnetic valve opening and closing time, cycle number, etc. The register is a storage unit in the control system with high-speed reading and writing capability. Once the strategy is written, the controller can read and execute it in real time, ensuring high synchronization and response capability for the spray process.

[0038] Directional control management of distributed components through the intelligent control system means using an embedded intelligent platform to finely and directionally manage each spray component distributed in the four layers of the water storage tank. The intelligent control system integrates a central processor, a data bus and a communication protocol, and can issue precise instructions to each execution unit such as a high-pressure pump, a rotating spray head and an electromagnetic valve. Directional control management selectively activates devices in a certain layer or area according to the strategy to achieve efficient removal of target dirt.

[0039] Further, the application further comprises: the first pump station pipeline topology, the first electromagnetic valve group and the first rotating nozzle array form a first device group, a first control mode is introduced, wherein the first device group is distributed on the top layer of the water storage tank, and the first control mode is a pulse type spiral coverage motion mode; a first state matrix and a first parameter control matrix are established according to the first device group, and a first control layer is driven to train by using the first control mode.

[0040] Specifically, the first pump station pipeline topology refers to the pipeline network structure connecting the high-pressure pump station and the nozzle, which is used to distribute water flow from the pump station to each nozzle according to a predetermined path. The first electromagnetic valve group is a group of programmable controlled electromagnetic valves that can quickly open and close the water flow to achieve precise control of different washing areas. The first rotating nozzle array is composed of multiple rotatable nozzles that can adjust the direction according to the control signal, thereby improving the washing coverage. The first pump station pipeline topology, the first electromagnetic valve group and the first rotating nozzle array form the first device group, which is installed on the top layer of the water storage tank to preferentially clean the dirt on the top area. In order to effectively control the first device group, a control mode of pulse type spiral coverage motion mode is introduced, and then intermittent high-pressure pulse water flow is used in the washing process, and a spiral path is formed by rotating the nozzle, thereby enhancing the cleaning effect on the top complex area.

[0041] Then, in order to achieve precise control, the state of the first device group is modeled. The first state matrix is a digital description of the working state of the devices in the first device group, including nozzle opening state, water pressure level, rotation angle and other dimensions. The first parameter control matrix defines the relationship between the control parameters of the first device group and the device response, such as the functional mapping relationship between the opening of the electromagnetic valve and the water flow. The first state matrix and the first parameter control matrix are combined and input into the control system, which can simulate the device response process under different control instructions, and then through training, the decision logic of the first control layer is optimized, so that it can better respond to different cleaning needs in actual operation. Table 1 is a table of first control layer device configuration and control parameters.

[0042] Table 1: First control layer device configuration and control parameter table ; ; Further, the application further comprises: determining a four-layer device group and introducing a four-layer control mode to drive a four-layer control unit to train; wherein the second device group is deployed in the middle layer of the water storage tank, the second control mode is a step type staggered scanning motion mode, the third device group is deployed in the lower layer of the water storage tank, the third control mode is a constant pressure type focusing jet motion mode, and the fourth device group is deployed in the bottom layer of the water storage tank, and the fourth control mode is a slope type vortex scouring motion mode.

[0043] Specifically, the four-layer device group is determined and the four-layer control mode is introduced, and the four-layer control unit is driven and trained, that is, in the whole water tank structure, the cleaning execution device is divided into four independent device systems corresponding to the four height levels, an independent device group is arranged at each level, and a specific spray cleaning motion mode is configured for each device group. By modeling and simulating the operation rules of each motion mode, the control logic of each layer is repeatedly trained, thereby forming an intelligent control unit adapted to the device layout. The device group refers to a complete cleaning system composed of a pump station pipeline, an electromagnetic valve group, and a rotating spray head, and the control unit is a control logic set for instructing and scheduling the device group.

[0044] In order to realize fine cleaning of different dirt distribution positions, the second device group is arranged in the middle layer area of the water tank, that is, the inner wall surface at the middle height. There are irregular stains caused by water surface fluctuation or sediment transfer in the middle layer of the water tank, so the stepped staggered scanning motion mode is more suitable. The second control mode simulates the stepped advancing mode, switches the height of the spray head in sequence and offsets laterally in each height section, realizes the staggered coverage of the cleaning path, and thus ensures the comprehensive coverage of the complex structure area. The third device group is arranged in the lower layer area of the water tank, that is, near the bottom but still above the water deposition line. The uniform but stubborn sediment is attached to the lower layer of the water tank, so the constant pressure type focused jet motion mode is more effective. The third control mode refers to concentrated jetting to the area where dirt is most concentrated with a continuous high-pressure water flow, dispersing the sediment layer through strong impact force, and realizing efficient removal in a short time. The constant pressure type control mode does not need to frequently open and close the electromagnetic valve, emphasizes the continuity of pressure and the accuracy of direction control, and is suitable for scenes that need to penetrate or break the dirt. Finally, the fourth device group is arranged in the bottom layer of the water tank, that is, the bottom of the water tank, which usually accumulates heavy residues, rust or sediment. Therefore, the bottom layer of the water tank is cleaned by using the slope type vortex scouring motion mode. The fourth control mode simulates the vortex motion of water flow under the guidance of slope, combines the guiding effect of the terrain, so that the dirt is lifted, peeled off and carried out with the water flow in the rotating water flow, which not only can clean the surface, but also can assist in carrying away the debris, and is suitable for bottom cleaning and sewage linkage processing.

[0045] Further, the application also includes: performing global scanning imaging on the spray cleaning target to determine a target image; identifying the target image, extracting dirt features, and performing spatial phase distribution based on the spray cleaning target to determine a dirt map; and performing dimension reduction processing on the dirt map to determine a reduced-order dirt map.

[0046] Specifically, the full-scan imaging of the spray target refers to the systematic and non-missing data collection of the surface to be cleaned by the scanning imaging device to obtain image information covering all positions. Full-scan includes multi-angle, multi-frequency optical, ultrasonic or laser imaging, which ensures that even subtle dirt can be captured, and the imaging result forms a high-resolution target image, which is a digital visual representation of the current state of the spray area, including dirt distribution, light reflection characteristics, surface texture and other dimensional information.

[0047] Then, identifying the target image and extracting the dirt features refer to applying image processing and pattern recognition algorithms to the image content after obtaining the target image to semantically analyze the image content, distinguish dirt and non-dirt areas, and extract relevant features. Dirt features may include gray / color difference, texture roughness, shape, coverage area, and adhesion thickness estimation. At the same time, spatial phase distribution analysis based on the spray target is also performed, i.e., in a three-dimensional space or a projection coordinate system, the phase (e.g., distance, angle, depth) relationship of each dirt point in space is constructed according to the geometric and directional properties of the spray target. The structured representation generated by the distribution is called a dirt map, which reflects the aggregation, directionality and intensity of dirt in spatial position and nature.

[0048] Then, the dimensionality reduction processing of the dirt map refers to compressing and extracting the original possibly high-dimensional, redundant, and noisy map data through statistical, learning or embedding methods, so as to retain the most critical information for spray decision and remove redundant dimensions. Dimensionality reduction processing methods can be realized by principal component analysis, sparse coding, autoencoder and other technologies. The processed result is called a reduced-order dirt map, which is a low-dimensional but highly expressive version, facilitating subsequent control unit rapid matching and decision-making, while retaining the most instructive patterns for cleaning in the original map and significantly reducing computational burden and storage requirements.

[0049] Further, the present application also includes: calling the participation control indicators, wherein the participation control indicators are determined by summarizing the participation control matrices of each control layer in the four-layer control unit; performing association of the dirt features and the participation control indicators to determine low-dimensional dirt features based on the strong correlation of each participation control indicator; associating the low-dimensional dirt features with the participation control indicators as a reference database; and matching and dimensionality reduction processing of the dirt map according to the reference database to determine the reduced-order dirt map.

[0050] Specifically, the reference parameter is extracted from the control system for control judgment and execution reference. The reference parameter is derived from each control layer in the four-layer control unit. In terms of technical structure, the reference parameter is summarized from the reference matrix of each layer of equipment. The reference matrix is a structured data table used to describe the operating parameters of each control layer, such as water pressure, jet angle, rotation rate, and electromagnetic valve opening and closing frequency. It also contains actual responses such as flow rate and cleaning efficiency. By integrating these data, the mapping relationship between the operating state of each layer of equipment and the control behavior can be obtained, and a complete control reference system can be constructed.

[0051] The association between the identified dirt feature data and the reference parameter of the control layer is cross-analyzed to establish a corresponding relationship between the two. The dirt feature refers to the morphological characteristics, adhesion degree, and coverage area of the dirt in the image, while the reference parameter refers to the control response of the equipment when dealing with different dirt conditions. By comparing and analyzing a large number of samples, the best control parameter for dealing with dirt can be found. Based on strong correlation, the key factors affecting the cleaning effect can be found, and precise dimensionality reduction can be achieved, i.e., only the most valuable dirt features are retained to form a low-dimensional dirt feature set.

[0052] Next, the association between the low-dimensional dirt feature and the reference parameter is used as a reference database, which means that the key dirt features after dimensionality reduction are combined with their corresponding best control parameters to form a database system for subsequent rapid matching and scheduling. The database records the control strategies that should be taken under specific dirt patterns. Each data can be represented as a pair of low-dimensional feature vectors and reference parameters. The existence of the database enables the intelligent control system to directly call the historical optimal strategy when facing new dirt patterns, without the need for head calculation, thereby improving the response speed and strategy accuracy.

[0053] Finally, the matching and dimensionality reduction of the dirt pattern based on the reference database is to compare the original dirt pattern obtained in real time with the low-dimensional feature set in the reference database to achieve rapid matching and adaptive dimensionality reduction. Then, the closest feature pattern is quickly found by using the existing experience model, and the matching control strategy is derived accordingly to form a reduced-order dirt pattern. The reduced-order pattern not only has lower dimensionality, but also has more control guidance significance, and can directly drive the subsequent cleaning behavior.

[0054] Further, the application also includes: importing the reduced-order dirt pattern into the four-layer control unit and performing state matrix initialization; deriving the reference matrix under the constraint of the hierarchical control mode to determine the multi-layer control strategy; and integrating the multi-layer control strategy in time and space to generate the overall machine control strategy.

[0055] Specifically, importing the reduced fouling map into the four-layer control unit means inputting the data model with simple structure and key fouling information after dimensionality reduction processing into the four independent control layers in the device system. The reduced fouling map is a compressed data set containing core features such as fouling intensity, type, and location in different regions, while the four-layer control unit is the four cleaning subsystems distributed in the top, middle, lower, and bottom layers of the water storage tank, each with independent control logic and hardware structure. The import process is automatically completed to facilitate subsequent precise execution.

[0056] Subsequently, state matrix initialization is performed, which means that after receiving the map information, the four-layer control unit starts the establishment process of the state matrix respectively and simultaneously. The state matrix is a data structure used to describe the current physical state of each device, sensor feedback, and actions to be performed, which can reflect specific parameters such as switch state, nozzle angle, and pressure setting of the current device. Parallel execution means that the four layers can be processed simultaneously without waiting for upper and lower levels, thereby improving reaction speed and operational efficiency.

[0057] Subsequently, parameter control matrix derivation is performed under the constraint of hierarchical control mode, which means generating the corresponding parameter control matrix according to the pre-set cleaning mode in each control layer and combining the current state matrix information. The control mode is a predefined action logic, for example, the top layer may use pulse spiral motion, and the bottom layer may use vortex flushing. The parameter control matrix is a control template representing the relationship between various control parameters and sensor feedback, which automatically adjusts cleaning parameters such as spray angle, duration, and interval period according to the requirements of the control mode. The derivation process is a multivariate calculation process aimed at forming a set of feasible and optimal control instructions.

[0058] Determining the multi-layer control strategy is to generate complete control strategies for each of the four layers based on the parameter control matrix. The multi-layer control strategy is an operation plan composed of motion paths, cleaning rhythm, and flow distribution of each layer of equipment, ensuring that each layer can efficiently complete its fouling cleaning task in the assigned area without device conflicts or energy waste.

[0059] Next, spatiotemporal integration of the multi-layer control strategy to generate the overall control strategy means that the independent control strategies generated by each of the four layers are unified and coordinated to form a global control model that can run collaboratively. Spatiotemporal integration means considering both the execution time coordination between different layers and the spatial action coordination to avoid overlap. For example, the top layer and the middle layer may have overlapping spray paths, which requires setting a time offset for execution; and the lower layer and the bottom layer use high-pressure systems simultaneously, which requires setting a time-sharing spray to avoid pressure overload. The overall control strategy is the final output of this integration process, ensuring that the entire system does not conflict or idle during operation and maximizing cleaning efficiency.

[0060] Further, the application also includes: traversing the multi-layer control strategy to time the washing cycle, the cycle number of times, and time sequence identify each layer control strategy; based on time sequence identification, integrating the multi-layer control strategy into a single time sequence chain with inter-layer time sequence logic, and generating a segmented overall control strategy.

[0061] Specifically, traversing the multi-layer control strategy means checking and processing the control scheme generated for each layer of equipment in the previous stage one by one, so as to extract the execution time, action sequence and cycle information involved therein. The control strategy includes parameters such as when each layer of nozzle starts, at what intensity it washes, and how long it maintains. The process of traversal is a line-by-line scanning of each layer strategy to ensure data integrity and lay the foundation for subsequent time coordination.

[0062] Time sequence identification of each layer control strategy based on washing cycle time and cycle number of times means that after traversing the strategy, according to the washing running time and repetition number of each layer of equipment, a clear time label is assigned to each operation. The washing cycle time is the total time required for each round of washing, and the cycle number of times is the number of repetitions of the washing action. Time sequence identification is a time coordinate system used to mark the start and end time of each action, thereby providing a time reference for the coordinated operation of multi-layer equipment.

[0063] Based on time sequence identification, integrating the multi-layer control strategy into a single time sequence chain with inter-layer time sequence logic means formulating a unified control sequence according to the time arrangement of each layer action to ensure that the cleaning process between layers is coordinated and orderly. Inter-layer time sequence logic is a rule system for handling the time relationship of multi-layer equipment operations, which is used to avoid action conflicts, overlapping energy consumption or physical interference between equipment. Based on the existing time sequence identification, the execution start time of each layer is automatically adjusted or staggered washing is set, so that the actions are arranged in a continuous and non-conflicting chain on a main time axis, which is a single time sequence chain.

[0064] Generating a segmented overall control strategy means taking the single time sequence chain as the basis of the overall strategy, and dividing it into several logical paragraphs, each of which corresponds to one or more execution phases of the washing task of the control layer. The segmented structure helps to improve the readability and maintainability of the strategy, and facilitates loading control instructions by segment, optimizing energy consumption management, and flexibly responding to sudden situations such as interruptions. Each segment has complete time definition and corresponding equipment action, and the entire cleaning process is completed step by step by loading these paragraphs.

[0065] Further, the application also includes: for the whole machine control strategy, positioning each timing strategy node based on the driving device, generating vertical synchronization signals, wherein each timing strategy node corresponds to a group of vertical synchronization signals; writing the vertical synchronization signals into the register, and performing signal space-time directional downward and device control driving.

[0066] Specifically, for the whole machine control strategy, each timing strategy node is positioned based on the driving device, and for each key action step in the whole control strategy, the specific device associated therewith is positioned and identified. The timing strategy node refers to each time point with control instructions and execution significance in the spray washing process, such as nozzle starting, pressure change, electromagnetic valve opening and closing, etc. The driving device includes high-pressure pump, electromagnetic valve, rotating nozzle, etc. Through the device-based positioning method, the actual execution device corresponding to each time node can be accurately identified, which prepares for subsequent generation of control signals.

[0067] To ensure that each control level is coordinated in time, according to the node positioning result, the corresponding control signal sequence is generated for each type of driving device, and the vertical synchronization signal is generated. The vertical synchronization signal is a control mechanism for time consistency in a multi-layer control system, which unifies the starting and response time of each control layer in key actions. For example, if the top nozzle needs to be started at 5 seconds and the lower electromagnetic valve needs to be closed at 6 seconds, two corresponding vertical synchronization signals will be generated and accurately aligned to the specific time. Each group of timing strategy nodes will be paired to form a group of synchronization signals, thereby maintaining the vertical coordination between different devices.

[0068] Writing the vertical synchronization signal into the register means writing the synchronization signal data generated in the previous step into the special storage module in the control hardware, i.e. the register, for subsequent quick calling and execution. The register is a small-capacity, fast-response storage component used for temporary storage of control signals and intermediate results. The signal writing process is an important step to realize the preset instructions, which ensures that each device can respond immediately when receiving the instructions.

[0069] The space-time directional downward and device control driving means that the control signals in the register are distributed to the corresponding control units according to the predetermined time sequence and spatial deployment, and the devices perform operations according to the plan. The space-time directional downward means that the control signals are not only sent in time sequence, but also must be spatially oriented according to the specific location of the device in the water tank, for example, the top nozzle receives layer one control signal, and the bottom electromagnetic valve receives layer four control signal. The device control driving means that these signals are finally converted into actual physical actions, such as water pressure starting, nozzle rotating, etc.

[0070] Further, the application also includes connecting a liquid level sensor, monitoring the water level according to the liquid level sensor to determine a water level signal, and controlling the water circulation in the entire spray-washing cycle according to the water level signal.

[0071] Specifically, connecting a liquid level sensor means that a special electronic device for detecting the water level in the water storage tank is communicatively connected to the entire control system. The liquid level sensor is a measuring element that can sense the change in liquid level in real time. Common types include capacitive, float ball, and ultrasonic. The liquid level sensor is installed inside or on top of the water storage tank to provide real-time feedback on the actual water level, providing data support for subsequent water management.

[0072] Monitoring the water level according to the liquid level sensor to determine a water level signal means that the liquid level in the water storage tank is continuously monitored by the liquid level sensor to generate an electronic signal that can be recognized and processed by the control system, i.e., the water level signal. The water level signal contains information such as water surface height, change trend, and threshold trigger. For example, when the liquid level drops below the set low threshold, the liquid level sensor will generate a low-level alarm signal to prompt the start of the water replenishment program.

[0073] Controlling the water circulation in the entire spray-washing cycle according to the water level signal means that the water level signal is used to comprehensively manage the water intake, use, and drainage during the entire spray-washing process. Water circulation control is to ensure that the spray-washing process is not interrupted due to lack of water, and is not wasted and fails due to overflow. The entire spray-washing cycle includes multiple stages, such as cleaning preparation in the pre-spray stage, high-pressure washing in the mid-spray stage, and residual liquid discharge in the end-spray stage, each stage has different water demand, and the water supply and drainage speed is dynamically adjusted according to the water level signal to realize intelligent water circulation scheduling.
