Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0040] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes said element.

[0041] With the deepening of national urbanization and the continuous improvement of people's environmental awareness, the demand for sanitation equipment continues to grow. The facades of urban bus stops, road signs, billboards, and other high-altitude facilities are also constantly increasing. Over time, these facades accumulate a large amount of dust, affecting the overall aesthetics of the city. Currently, road cleaning is often carried out by road maintenance vehicles.

[0042] Traditional road maintenance vehicle control systems typically employ two independent control modules. Specifically, the industrial controller handles the logic control of the vehicle's electrical system, while the motor controller focuses on the drive and protection of the water pump motor. However, this separate architecture presents several problems: First, the communication between the two main controllers via external wiring is complex, leading to cumbersome wiring harness layout and increased wiring difficulty and troubleshooting workload. Second, the two independent control modules are susceptible to electromagnetic interference during information exchange, reducing the reliability of control signal transmission, especially in complex operating environments. Furthermore, the data processing requires multiple transfers, resulting in poor timeliness and failing to meet the demands for rapid response.

[0043] Furthermore, in traditional systems, the control box, as the primary human-machine interface device, can only perform simple on / off control and mode switching, and cannot display relevant operating parameters or provide alarm information. This limitation makes it difficult for users to flexibly adjust the operating mode according to actual conditions during use, and also makes it impossible to obtain equipment operating status and fault information in a timely manner, thus affecting the overall ease of operation and maintenance efficiency. Based on this, embodiments of this application provide a road maintenance vehicle control system and a road maintenance vehicle to solve the above problems.

[0044] This application provides a road maintenance vehicle control system. Figure 1 Please refer to the schematic diagram of a road maintenance vehicle control system provided in this application embodiment. Figure 1 The road maintenance vehicle control system includes a dual-core module 10, a human-machine interaction module 20, and an operation module 30. The dual-core module 10 is communicatively connected to the human-machine interaction module 20 and the operation module 30, and the dual-core module includes an industrial controller and a motor controller.

[0045] In this embodiment, the human-computer interaction module can be used to obtain the work instructions issued by the user through the operation panel and send the work instructions to the dual-core module. The dual-core module can be used to control the work module to perform the work according to the work instructions.

[0046] Optionally, the dual-core module may include an industrial controller and a motor controller, which integrate the control logic and signal processing capabilities of both. The industrial controller is the main controller, used to control the entire electrical system of the road maintenance vehicle, serving as the brain of the road maintenance vehicle's control system. The motor controller is mainly used to control the on / off switching of the water pump motor and high-voltage circuit, as well as protection functions such as overcurrent, overtemperature, and undervoltage.

[0047] Clearly, this integrated design, combining an industrial controller and a motor controller via a dual-core module, not only simplifies the hardware structure but also enables the industrial controller and motor controller to transmit control commands internally. This allows for faster and more lag-free command transmission, ensuring the entire system remains highly efficient and stable under complex operational demands. Furthermore, because the dual-core module allows for internal communication, no external circuitry is required, simplifying the vehicle wiring harness and eliminating a significant amount of troubleshooting work.

[0048] In one example Figure 2 Please refer to the structural diagram of the dual-core module. Figure 2 The dual-core module 10 includes an industrial controller, a motor controller, and a power chip, wherein the power chip is used to supply power to the motor. In this example, the motor refers to a water pump motor.

[0049] In this embodiment, the human-machine interaction module can send the acquired work instructions to the dual-core module, which can then precisely control the work module according to the received work instructions. For example, when the user selects a specific work mode, the dual-core module can parse the instruction and convert it into a specific control signal to drive the work module to complete the corresponding task.

[0050] The road maintenance vehicle control system provided in this application embodiment may include a dual-core module, a human-machine interface module, and an operation module. The human-machine interface module can obtain operation instructions issued by the user, and the dual-core module can control the operation module to perform operations according to the operation instructions. Since the dual-core module can integrate the industrial controller and the motor controller, the internal communication mechanism of the dual-core module can replace the external line connection, preventing signal interference during signal transmission and the problem of poor timeliness caused by multiple relays. This can improve the reliability and timeliness of the road maintenance vehicle control, and at the same time simplify the layout of the vehicle wiring harness.

[0051] In one possible implementation, the human-computer interaction module may include a display module and control buttons to replace the traditional operation box.

[0052] The control button is used to send the operation instruction to the dual-core module in response to the user's control operation, and the display module is used to receive the display information sent by the dual-core module and display the display information.

[0053] In practical applications, in order to achieve multiple function selections, the control buttons can include multiple buttons, such as power switch button, spray bar / dredging switch button, direction (up, down, left, right) selection button, motor start button, motor speed selection button, operation mode selection button, interface switching button, etc.

[0054] Understandably, when a user presses the corresponding control button, the human-machine interface module can send the corresponding command to the dual-core module. For example, when a user presses the motor speed button, the human-machine interface module can send a command to the dual-core module to adjust the generator speed.

[0055] Optionally, the dual-core module can also send some information to the display module for display. In this embodiment, the displayed information can be various information about the operation of the road maintenance vehicle control system, including the operating status of various components during the control process, such as displaying the current operating mode, alarm information, fault information, communication status feedback, etc.

[0056] In addition, the displayed information can also be information queried by the user. For example, the user can input a query command through the display module, and the display module can send the query command to the dual-core module, which will then provide the query content.

[0057] Understandably, compared to traditional control boxes, human-computer interaction modules can significantly improve the selectivity and convenience of operation, while also providing users with intuitive status displays and fault alarms.

[0058] In this embodiment, considering that related technologies often use an electrical control box as the core power distribution and protection device, although the electrical control box can meet basic requirements, its complex design structure also leads to a decrease in system reliability. Specifically, when the vehicle is in a complex operating environment, the components inside the electrical control box may fail due to long-term operation or external interference, thereby affecting the normal operation of the entire system. In addition, electrical control boxes are usually large in size, making installation and maintenance inconvenient, further increasing the cost and complexity of the system.

[0059] Based on this, the road maintenance vehicle control system provided in this application embodiment can replace the traditional electrical control box with a fuse relay box, so as to improve the protection level and system reliability of the entire control system while reducing costs.

[0060] Specifically, in Figure 1 On this basis, Figure 3 For another structural schematic diagram of the road maintenance vehicle control system provided in this application embodiment, please refer to [link / reference]. Figure 3 The operation module 30 may include a water pump motor 31 and a water spraying operation module 32. The maintenance vehicle control system may also include a low-voltage power supply module 40, a high-voltage power supply module 50, and a fuse relay box 60. The low-voltage power supply module 40 is electrically connected to the human-machine interaction module 20, the industrial controller in the dual-core module 10, and the water spraying operation module 32 through the fuse relay box 60. The high-voltage power supply module 50 is electrically connected to the motor controller in the dual-core module 10, and the motor controller is electrically connected to the water pump motor 31.

[0061] In this embodiment, the low-voltage power supply module can be used to provide low-voltage power to the human-machine interaction module, the industrial controller in the dual-core module, and the water spraying operation module, respectively. The high-voltage power supply module can be used to provide high-voltage power to the motor controller, so that the motor controller can provide high-voltage power to the water pump motor when the water pump motor starts and the maintenance vehicle control system is fault-free. The fuse relay box can be used to provide power supply protection when the low-voltage power supply module provides low-voltage power.

[0062] Optionally, the water spraying module refers to the module specifically responsible for performing the water spraying task during the road maintenance process, while the water pump motor is the core component that provides power for the water spraying operation.

[0063] Optionally, the high-voltage output terminal of the motor controller is connected to the water pump motor to control the water pump motor.

[0064] Optionally, the low-voltage power module may include a chassis low-voltage system, a chassis docking module, and an upper-mount power distribution system, wherein the upper-mount power distribution system can obtain low-voltage power from the chassis low-voltage system through the chassis docking module; the high-voltage power module may be the chassis high-voltage power distribution system.

[0065] In this embodiment, after the chassis key switch is turned on and high voltage is applied, the vehicle enters the driving state but is not yet in the working state. When the upper body start button on the operation panel of the human-machine interaction module is pressed, the upper body starts. The low-voltage power supply module provides low-voltage power supply to the human-machine interaction module, the industrial controller in the dual-core module and the water spraying operation module through the fuse relay box to ensure that each module can complete the initialization preparation and enter the standby operation state.

[0066] Understandably, the low-voltage power module is mainly used to provide low-voltage power distribution for the upper-mount control system, while the high-voltage power system is mainly used to provide high-voltage power distribution for the water pump motor. In order to ensure that the system starts up gradually under safe and stable conditions and to avoid the risk of equipment damage due to voltage surges, low-voltage power supply can be provided first when the upper-mount power switch is turned on, and high-voltage power supply can be provided after a preset delay (e.g., 2 seconds).

[0067] In this embodiment, when the motor start button on the control panel is pressed, the dual-core module can perform fault diagnosis, such as checking whether the CAN communication is normal, and checking whether the water level in the water tank is normal and whether there is a motor drive fault through the CAN communication.

[0068] If there is no fault, the water pump motor can be started. That is, the motor controller can provide high voltage to the water pump motor and control the water pump motor to run at the default speed.

[0069] If a fault is found, the dual-core module can send the specific fault information to the human-machine interface module for feedback. Then, maintenance personnel can troubleshoot and repair the fault based on the specific fault displayed by the human-machine interface module, thus improving maintenance efficiency.

[0070] Optionally, during normal operation, the control system can also detect faults and display them on the operation panel, such as water shortage alarms, vehicle lock alarms, communication alarms, etc. In addition, the operation panel can also display relevant statuses of the road maintenance vehicle, such as real-time CAN communication status, motor and electric drive status (including high voltage status, speed status, electric drive temperature, motor temperature, current status, etc.), and input / output parameters of the dual-core module, etc. Understandably, displaying key information also improves the convenience of using and debugging the road maintenance vehicle.

[0071] In this embodiment, the fuse relay box serves as the main connection path between the human-machine interface module and the dual-core module, controlling the electrical connection of the entire upper electrical system. It not only provides a reliable electrical connection between the human-machine interface module and the dual-core module, but also effectively replaces the traditional electrical control box design, thereby reducing costs and improving the protection level.

[0072] Optionally, Figure 4 and Figure 5 For a structural example diagram of a road maintenance vehicle, please refer to [link / reference]. Figure 4 and Figure 5 For ease of operation, the human-machine interface module can be installed on the cab control panel, the fuse and relay box can be installed on the rear side of the passenger seat, and the dual-core module can be installed on the front baffle of the rear water pump.

[0073] Alternatively, in the actual application of road maintenance vehicles, water spraying and dredging operations are usually two independent operating modes. However, if separate position control buttons are set to achieve position control in these two operating modes, it may not only increase the complexity of the control panel, but may also cause users to accidentally touch or confuse the operation, thereby affecting the efficiency and accuracy of the operation.

[0074] Therefore, it is clear that there is an urgent need to solve the above problems in order to optimize the control system architecture, reduce the need for multiple independent buttons, and thus simplify the design of the control panel.

[0075] Specifically, since the boom position drive module and the dredging position drive module correspond to the position adjustment requirements of different operating modes, and their operating states are usually mutually exclusive (i.e., only one operating mode is allowed to run at a time), a unified switching module can be introduced to coordinate the switching of their operating states. In this way, users do not need to configure separate control buttons for each operating mode, but can switch the position drive module through a single switching command.

[0076] Specifically, in Figure 3 On this basis, Figure 6 For another structural schematic diagram of the road maintenance vehicle control system provided in this application embodiment, please refer to [link / reference]. Figure 6 The water spraying operation module 32 includes a spray boom / dredging switching module 320, a spray boom posture driving module 321, and a dredging posture driving module 322. The spray boom / dredging switching module 320 is communicatively connected to the dual-core module 10 and electrically connected to the fuse relay box, the spray boom posture driving module 321, and the dredging posture driving module 322, respectively. The operation instructions include switching instructions.

[0077] Based on this, the dual-core module is also used to control the spray boom / dredging switching module to perform a switching operation when a switching command is received. This is to control the spray boom posture driving module to stop working and control the dredging posture driving module to enter the working state when the spray boom posture driving module is in the working state, or to control the dredging posture driving module to stop working and control the spray boom posture driving module to enter the working state when the dredging posture driving module is in the working state.

[0078] Optionally, the low-voltage power supply module can also be electrically connected to the spray boom / dredging switching module via a fuse relay box to provide low-voltage power to the spray boom / dredging switching module. The spray boom / dredging switching module can selectively supply low-voltage power to the spray boom posture drive module or the dredging posture drive module in response to a switching command.

[0079] In this embodiment, when the user issues a switching command via the operation panel, the command is first transmitted to the dual-core module. The dual-core module then controls the spray boom / dredging switching module to perform the switching operation according to the command. For example, if the current spray boom posture driving module is in a standby state, upon receiving the switching command, the dual-core module will control the spray boom / dredging switching module to switch its working mode to the dredging active state, simultaneously stopping the operation of the spray boom posture driving module and putting the dredging posture driving module into a standby state. Conversely, if the current dredging posture driving module is in a standby state, the dual-core module will control the spray boom / dredging switching module to switch back to the spray boom active state upon receiving the switching command, thereby stopping the operation of the dredging posture driving module and starting the spray boom posture driving module.

[0080] In this embodiment, when it is necessary to adjust the position and angle of the spray boom or dredging, the user must first adjust the gear of the spray boom / dredging switching module through the operation panel to make it correspond to the correct switch state so that the corresponding position and angle driving module is in the ready-to-operate state. Then, the user can select the corresponding position and angle adjustment button (up, down, left, right) to perform the specific position and angle adjustment operation.

[0081] Understandably, by introducing a boom / dredging switching module and combining it with a dual-core module to parse and execute switching commands, the system can quickly switch between the two operating modes of boom position adjustment and dredging position adjustment. This effectively reduces the number of independent buttons on the control panel and ensures that the position adjustment operation is accurate after each switch, improving the system's reliability and ease of use, and providing strong technical support for the actual operation of road maintenance vehicles.

[0082] In one possible implementation, the aforementioned spray boom posture driving module 321 may include a direction adjustment push rod, and the dredging posture driving module 322 may include a direction adjustment motor. Specifically, the direction adjustment push rod may include left and right electric push rods and up and down electric push rods, used to control the posture changes of the front spray frame in the horizontal and vertical directions; the dredging posture driving module may include left and right rotary motors and up and down rotary motors, used to control the rotation of the fixed-point spray in the corresponding direction.

[0083] Understandably, all of the above modules are connected to the spray boom / dredging switching module via electrical connection and are uniformly scheduled by the dual-core module.

[0084] Optionally, the spray boom / dredging switching module can be a relay switching device, located in the fuse relay box, which coordinates the working states of the spray boom posture drive module and the dredging posture drive module by receiving switching commands from the dual-core module.

[0085] In this embodiment, the operation command may further include a direction adjustment command. Therefore, the dual-core module can also be used to control the direction adjustment push rod to adjust the direction of the front water spray frame when it receives a direction adjustment command and the spray boom posture drive module is in a ready-to-operate state, thereby adjusting the water spray direction of the front water spray frame; and to control the direction adjustment motor to adjust the direction of the fixed-point water spray when it receives a direction adjustment command and the dredging posture drive module is in a ready-to-operate state, thereby adjusting the fixed-point water spray direction.

[0086] In this embodiment, the direction adjustment command can be issued by the user through the operation panel and transmitted to the dual-core module. The dual-core module can precisely control the spray boom posture drive module or the dredging posture drive module according to the received direction adjustment command and the current status of the operation module.

[0087] Optionally, in practical applications, users can use the four buttons (left, right, up, down) on the control panel to simulate the function of the joystick and adjust the mass in the downward direction, so as to achieve precise adjustment of the position and posture of the spray bar or dredging equipment.

[0088] In one possible implementation, when the spray boom posture drive module is in standby mode, the dual-core module, upon receiving a direction adjustment command, parses the command into specific motion parameters and controls the left / right or up / down electric actuators to perform corresponding extension / retraction movements. Specifically, if the user presses the "left" or "right" button on the control panel, the dual-core module controls the left / right electric actuators to adjust horizontally to adjust the front spray direction; if the user presses the "up" or "down" button, the dual-core module controls the up / down electric actuators to adjust vertically, thereby achieving precise adjustment of the water spray angle.

[0089] In another possible implementation, when the dredging posture drive module is in standby mode, the dual-core module will also convert the direction adjustment command into a corresponding motor control signal upon receiving it. At this time, if the user presses the "left" or "right" button, the dual-core module will control the left and right rotary motors to rotate horizontally to adjust the direction of the fixed-point water spray; if the user presses the "up" or "down" button, the dual-core module will control the up and down rotary motors to rotate vertically, thereby achieving precise control of the fixed-point water spray angle.

[0090] It should be noted that the position adjustment can be made in real time during the water spraying operation based on the actual application situation, or it can be made initially based on the water spraying operation to be carried out before the water spraying operation is carried out.

[0091] Alternatively, in order to further reduce the number of independent buttons on the control panel and simplify the design of the control panel, these buttons can also be used as selection buttons for motor speed and operating mode, further improving the system's functional integration and user experience.

[0092] Optionally, the operation instruction can also include a specific water spraying instruction. In this case, the dual-core module can control the corresponding water valve to open and perform water spraying operations after receiving the specific water spraying instruction. However, in related technologies, the opening and closing of water valves usually relies on air pumps and air valves in the air circuit system. Although this design can meet the needs of water spraying operations to a certain extent, it has obvious drawbacks.

[0093] First, the pneumatic system has a complex structure, including multiple components such as air pumps and valves. This not only increases the system's manufacturing cost but also raises the difficulty of installation and maintenance. Second, the pneumatic system has relatively low reliability, especially during long-term operation or under harsh conditions. Valves are prone to failure due to pressure fluctuations or seal failure, thus affecting the normal operation of water spraying. Finally, the pneumatic system has a relatively short lifespan, with frequent pressure changes and gas leaks further accelerating its aging process. For example, in practical applications, the use of air pumps and valves not only requires additional energy support but also necessitates regular inspection and maintenance to prevent gas leaks or abnormal pressure. Furthermore, the complexity of the pneumatic system makes troubleshooting and repair more difficult, thereby affecting the stability and economy of the entire maintenance vehicle control system.

[0094] Therefore, optimizing the water valve control method to reduce system costs, improve operational reliability, and extend service life has become an urgent problem to be solved.

[0095] Based on this, the road maintenance vehicle control system provided in this application can simplify the control structure by introducing an electric actuator to replace the traditional pneumatic system. Since the electric actuator directly controls the opening and closing of the water valve through mechanical transmission, it eliminates the need for complex pneumatic components, thus significantly reducing the number of system parts and connections. Compared to the traditional pneumatic system, controlling the water valve via an electric actuator not only effectively reduces the system's manufacturing and maintenance costs but also significantly improves the stability and lifespan of the water valve control. Furthermore, it reduces operational interruptions caused by pneumatic system failures, thereby improving the overall performance and user experience of the road maintenance vehicle.

[0096] Specifically, in Figure 3 On this basis, Figure 7 For another structural schematic diagram of the road maintenance vehicle control system provided in this application embodiment, please refer to [link / reference]. Figure 7 The water spraying operation module 32 also includes an IO module 323 and a water valve control push rod 324. The IO module 323 is communicatively connected to the dual-core module 10 and the water valve control push rod 324 respectively. The IO module is also electrically connected to the fuse relay box. The operation instructions also include water spraying instructions.

[0097] In this embodiment, the dual-core module is also used to control the water valve control push rod to extend through the IO module when a water spraying command is received, so that the water valve corresponding to the water valve control push rod opens, and to control the water pump motor to start for water spraying operation.

[0098] In this embodiment, the water valve control push rod is an electric push rod, which can open or close the relevant water valve through mechanical transmission. It should be noted that, under normal conditions, the water valve control push rod is in the retracted state, and the corresponding water valve remains closed to ensure that the system does not accidentally spray water when it does not receive a water spraying command.

[0099] In this embodiment, when the user issues a water spray command via the control panel, the command is first transmitted to the dual-core module. The dual-core module parses the command content and generates a corresponding control signal. Subsequently, the signal is transmitted to the water valve control push rod via the IO module, causing it to extend. When the water valve control push rod extends, it triggers the associated water valve mechanism, thereby opening the water valve and allowing water to flow through for water spraying.

[0100] Furthermore, during the execution of the above steps, the dual-core module is not only responsible for controlling the movement of the water valve control lever, but also for simultaneously starting the water pump motor to provide the water pressure required for spraying. Specifically, while the water valve is opening, the dual-core module can also control the water pump motor to start running via the motor controller according to the spraying command. This process ensures the smooth operation of the water system and the timeliness of the spraying operation.

[0101] Optionally, the operation panel can be equipped with operation modes for users to select. To prevent accidental touches, an operation start button can also be provided. That is, users can first select a specific operation mode and then press the operation start button to start the operation mode.

[0102] Optionally, after the water spraying operation is completed, the user can issue a command to stop the water spraying via the control panel. The dual-core module will receive this command and control the water valve control lever to retract via the I / O module. When the water valve control lever retracts, the water valve closes, thereby interrupting the water supply and completing the closed-loop control of the entire water spraying operation. Optionally, the I / O module can not only realize command transmission between the dual-core module and the water valve control lever, but also monitor relevant parameters in real time. For example, it can monitor the main input and output parameters of the industrial controller.

[0103] Specifically, when the dual-core module receives the operation command issued by the user through the control panel, it sends the parsed control signal to the IO module. During the above steps, the IO module is not only responsible for accurately transmitting the signal to the corresponding water valve control lever to complete the opening or closing operation of the water valve, but also monitors the status changes during signal transmission in real time and feeds this status information back to the dual-core module, thereby ensuring the transparency and traceability of the entire control process.

[0104] For example, when the dual-core module receives a front spray command, it sends an extension signal to the spray boom valve push rod via the I / O module, causing the spray boom valve on the front spray frame to open. During this process, the I / O module monitors the push rod's movement status in real time, including but not limited to key parameters such as whether the push rod has successfully extended and whether it has reached the preset position. If any abnormality occurs (such as the push rod getting stuck or failing to extend fully), the I / O module will promptly feed back the fault information to the dual-core module so that the system can take appropriate protective measures.

[0105] Optionally, there can be multiple water valve control push rods, each corresponding to a different water spraying operation mode.

[0106] In one possible implementation, the water valve control push rod may include a spray bar water valve push rod, and the water spray command may include a front spray command. The dual-core module can also be used, upon receiving a front spray command, to control the extension of the spray bar water valve push rod via the I / O module to open the spray bar water valve on the front spray frame, and to control the water pump motor to start for front spraying operations.

[0107] In this embodiment, the water spraying operation mode can be front spraying, and the water valve control push rod can be the spray boom water valve push rod. When the user issues a front spraying command through the operation panel, the human-machine interface module can forward the command to the dual-core module. After receiving the front spraying command, the dual-core module parses the command content and generates a corresponding control signal, and then transmits the signal to the spray boom water valve push rod through the IO module, causing it to extend. Specifically, when the spray boom water valve push rod extends, it will trigger the associated front spray water valve mechanism, thereby opening the front spray water valve and allowing water to flow through to achieve the front spraying operation.

[0108] Furthermore, during the execution of the above steps, the dual-core module is not only responsible for controlling the movement of the spray boom water valve push rod, but also needs to synchronously start the water pump motor to provide the water pressure required for spraying. Specifically, when the front spray valve opens, the dual-core module, according to the requirements of the front spray command, controls the water pump motor to start running through the motor controller, thereby ensuring that the water flow can be sprayed out from the front spray frame with sufficient pressure. Understandably, the front spray direction can also be adjusted through the spray boom posture drive module during front spraying operations, which will not be elaborated on here.

[0109] In another possible implementation, the water valve control push rod also includes a fixed-point sludge removal push rod, and the water spraying command also includes a fixed-point spraying command; the dual-core module is also used to control the fixed-point sludge removal push rod to extend so that the fixed-point water spraying valve opens when the fixed-point spraying command is received, and to control the water pump motor to start to carry out fixed-point water spraying operation.

[0110] In this embodiment, the water spraying operation mode can be a fixed-point spraying operation, and the water valve control push rod can be a fixed-point sludge removal push rod. When the user issues a fixed-point spraying command through the operation panel, the human-machine interface module can forward the command to the dual-core module. After receiving the fixed-point spraying command, the dual-core module parses the command content and generates a corresponding control signal, and then transmits the signal to the fixed-point sludge removal push rod through the IO module, causing it to extend. Specifically, when the fixed-point sludge removal push rod extends, it will trigger the associated fixed-point water spraying valve mechanism, thereby opening the fixed-point water spraying valve and allowing water to flow through to achieve the fixed-point water spraying operation.

[0111] Furthermore, during the execution of the above steps, the dual-core module is not only responsible for controlling the movement of the spray bar water valve push rod, but also needs to synchronously start the water pump motor to provide the water pressure support required for spraying. Specifically, when the fixed-point spray valve opens, the dual-core module controls the water pump motor to start running through the motor controller according to the requirements of the fixed-point spray command, thereby ensuring that the water flow can be sprayed out at a fixed point with sufficient pressure.

[0112] Understandably, the direction of the spray can be adjusted by the dredging posture drive module when performing fixed-point water spraying operations, which will not be elaborated on here.

[0113] In another possible implementation, the water valve control push rod also includes a spray gun valve electric push rod, and the water spraying command also includes a handheld spray gun water spraying command; the dual-core module is also used to control the spray gun valve electric push rod to extend so that the handheld spray gun water valve opens when the handheld spray gun water spraying command is received, and to control the water pump motor to start so as to carry out the handheld spray gun water spraying operation.

[0114] In this embodiment, the water spraying operation mode can be a handheld spray gun operation, and the water valve control lever can be a spray gun valve electric lever. When the user issues a handheld spray gun water spraying command through the operation panel, the human-machine interface module can forward the command to the dual-core module. After receiving the handheld spray gun water spraying command, the dual-core module parses the command content and generates a corresponding control signal, and then transmits the signal to the spray gun valve electric lever through the IO module, causing it to extend. Specifically, when the spray gun valve electric lever extends, it will trigger the associated handheld spray gun water valve mechanism, thereby opening the handheld spray gun water valve and allowing water to flow through to achieve handheld spray gun water spraying operation.

[0115] Furthermore, during the execution of the above steps, the dual-core module is not only responsible for controlling the movement of the electric actuator of the spray gun valve, but also needs to synchronously start the water pump motor to provide the water pressure required for spraying. Specifically, when the handheld spray gun water valve is opened, the dual-core module can control the water pump motor to start running through the motor controller according to the water spray command of the handheld spray gun, thereby ensuring that the water flow can be sprayed out with sufficient pressure.

[0116] In another possible implementation, the water valve control push rod may also include a right-angle spray electric push rod, and the water spray command may also include a right-angle spray command; the dual-core module is also used to control the right-angle spray electric push rod to extend to open the right-angle spray valve through the IO module when the right-angle spray command is received, and to control the water pump motor to start to perform the right-angle spray operation.

[0117] In this embodiment, the water spraying operation mode can be a right-corner spray operation, and the water valve control push rod can be a right-corner spray electric push rod. When the user issues a right-corner spray command through the operation panel, the human-machine interface module can forward the command to the dual-core module. After receiving the right-corner spray command, the dual-core module parses the command content and generates a corresponding control signal, and then transmits the signal to the right-corner spray electric push rod through the IO module, causing it to extend. Specifically, when the right-corner spray electric push rod extends, it will trigger the associated right-corner spray valve mechanism, thereby opening the right-corner spray valve and allowing water to flow through to achieve the right-corner spraying operation.

[0118] Furthermore, during the execution of the above steps, the dual-core module is not only responsible for controlling the movement of the right corner spray electric actuator, but also needs to synchronously start the water pump motor to provide the water pressure required for spraying. Specifically, when the right corner spray valve opens, the dual-core module can control the water pump motor to start running through the motor controller according to the requirements of the right corner spray command, thereby ensuring that the water flow can be sprayed out with sufficient pressure.

[0119] It should be noted that the water spraying operation mode includes, but is not limited to, front spraying operation, fixed-point spraying operation, handheld spray gun operation, and right corner spraying operation. Considering the potential resource conflicts or operational chaos that may occur with multiple operation modes, an interlocking mechanism can be used to manage multiple water spraying operation modes to ensure that only one mode is active at any given time, thereby avoiding resource conflicts or operational chaos caused by multiple modes running simultaneously.

[0120] Optionally, to better meet different needs in practical applications, the operation instruction may also include a motor speed adjustment instruction. The dual-core module is also used to adjust the speed of the water pump motor according to the motor speed adjustment instruction when it receives the motor speed adjustment instruction.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
