However, existing cleaning robots integrate water supply equipment into the cleaning robot, and the module used to control the water supply equipment is also integrated into the cleaning robot's control system. Due to the harsh working environment of the cleaning robot, the circuit of the water supply equipment control part is easily damaged. If damaged, the entire cleaning robot needs to be disassembled and repaired, which affects the use of the cleaning robot.

[0010] The beneficial effect of this technical solution is that, by separating the water supply equipment control system from the cleaning robot body, a modular design is achieved, which is convenient for maintenance and upgrading. The circuit of the water supply equipment control part is separated from the cleaning robot body and does not need to be set inside the cleaning robot body in a harsh environment, which reduces the risk of circuit damage and improves the stability and reliability of the entire system. When a problem occurs in the water supply equipment control part, there is no need to disassemble the entire cleaning robot. It is only necessary to repair the water supply equipment control system part or replace it with a new water supply equipment control system, which greatly simplifies the maintenance process and reduces maintenance costs.

[0032] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] See also Figure 1 The present invention provides a water supply equipment control system for a cleaning robot. The cleaning robot includes a remote controller, a robot body and a water supply equipment that are separately arranged. The water supply equipment control system includes:

[0034] A remote control device circuit, which is provided in the remote control and includes a first communication module and a remote control main control module. The remote control main control module is used to receive water supply control instructions for the cleaning robot, generate a water supply control signal, and send it through the first communication module;

[0035] Water supply equipment circuit, the water supply equipment circuit is arranged in the water supply equipment, including a water supply main control module, a water pump drive circuit and a second communication module; the second communication module and the first communication module are used to establish a communication connection between the remote control device and the water supply equipment circuit to transmit the water supply control signal; the water supply main control module and the second communication module are electrically connected to receive the water supply control signal and output the water pump drive control signal; the water pump drive circuit and the water supply main control module are electrically connected to receive the water pump drive control signal and drive the water supply equipment to supply water to the robot body of the cleaning robot.

[0036] The remote control main control module and the water supply main control module may each include a main control chip, which may be a microcontroller (MCU) such as an ARM microcontroller or a MIPS microcontroller. The main control chip includes interfaces such as a general purpose input and output interface (GPIO), which can be used for transmission and exchange of internal and external chip signals, level conversion and driving of data provided within the chip to generate external data signals, and / or level conversion of data from outside the chip to obtain data signals that can be recognized by the chip.

[0037] The remote control device circuit is composed of a first communication module and a remote control main control module. The remote control main control module is responsible for receiving the water supply control instructions issued by the operator to control the water supply of the cleaning robot. After receiving the instruction, the remote control main control module generates a corresponding water supply control signal and sends it to the water supply device circuit through the first communication module. The water supply equipment circuit includes a water supply main control module, a water pump drive circuit and a second communication module. The second communication module establishes a communication connection with the first communication module to ensure that the water supply control signal can be transmitted from the remote control device circuit to the water supply device circuit. Its connection method is, for example, a wireless connection method such as a zigbee communication connection or a 4G communication connection, and this application does not limit it. After receiving the water supply control signal, the water supply main control module outputs a water pump drive control signal according to the signal content. The water pump drive circuit receives the water pump drive control signal and drives the water pump to work accordingly to supply water to the main body of the cleaning robot to achieve the purpose of cleaning the solar panel.

[0038] The advantage of this embodiment is that by separating the water supply equipment control system from the cleaning robot body, a modular design is achieved, which is convenient for maintenance and upgrading. The circuit of the water supply equipment control part is separated from the cleaning robot body and does not need to be set up in the cleaning robot body in a harsh environment, which reduces the risk of circuit damage and improves the stability and reliability of the entire system. When a problem occurs in the water supply equipment control part, there is no need to disassemble the entire cleaning robot. It is only necessary to repair the water supply equipment control system part or replace it with a new water supply equipment control system, which greatly simplifies the maintenance process and reduces maintenance costs. The communication connection between the first communication module and the second communication module ensures the accurate transmission of the water supply control signal and improves the accuracy of the water supply control. This embodiment takes into account the needs of solar panel cleaning and has good adaptability and practicality. At the same time, it reduces the need for manual cleaning and reduces labor costs.

[0039] In summary, the modular design and remote control provided by the water supply control system not only improve the stability of the cleaning robot, but also simplify maintenance procedures and reduce maintenance costs. The cleaning robot's main body and water supply system are separated, and the water supply circuit is located within the water supply system. This separates the robot's main body from the robot's main body, making it less susceptible to damage and reducing the impact on the robot's use.

[0040] See also Figure 2 In some embodiments, the water pump driving circuit includes a transistor Q1, a MOS transistor Q2, a first diode D1, a first resistor R1 and a fifth resistor R5, wherein the first diode D1 is a voltage stabilizing diode;

[0041] The base of the transistor Q1 is electrically connected to the signal output end of the water supply main control module for receiving the water pump drive control signal. The emitter of the transistor Q1 is grounded, the collector of the transistor Q1 is electrically connected to the gate of the MOS transistor Q2, the source of the MOS transistor Q2 is connected to the power supply voltage, the drain of the MOS transistor Q2 is connected to the first terminal of the water supply device, and the second terminal of the water supply device is connected to VCC_GS and grounded through the fifth resistor R5; the cathode of the first diode D1 is electrically connected to the source of the MOS transistor Q2, and the anode of the first diode D1 is electrically connected to the collector of the transistor Q1; the first resistor R1 and the first diode D1 are connected in parallel.

[0042] In some embodiments, a second resistor R2 is further provided between the anode of the first diode D1 and the collector of the transistor Q1, a third resistor R3 is further provided between the base of the transistor Q1 and the signal output end of the water supply main control module, a fourth resistor R4 is further provided between the base and the emitter of the transistor Q1, and a second diode D2 is further provided between the first terminal and the second terminal of the water supply equipment, the anode of the second diode D2 is connected to the second terminal of the water supply equipment (terminal 2 of CN25), and the cathode is connected to the first terminal of the water supply equipment (terminal 1 of CN25).

[0043] See also Figure 2 In the initial state, assuming the power supply voltage is 24V, the voltage limit of the Zener diode (first diode D1) is set to 10V to prevent overvoltage damage to subsequent circuit components. At this time, MOS transistor Q2 is in the off state because its gate (G) voltage is lower than the threshold voltage (Vth). The source (S) is grounded, and the drain (D) is connected to the load (which can be understood as the water pump connected to the first and second terminals of the water supply equipment).

[0044] During the conduction process, when the water pump drive control signal acts on the base (B) of transistor Q1, transistor Q1 conducts, and collector (C) current flows (through the second resistor R2) to the gate of MOS transistor Q2. Due to the amplification effect of transistor Q1, the gate voltage rises. When it exceeds the threshold voltage (Vth), MOS transistor Q2 conducts. At this point, current flows from the positive terminal of the power supply, stabilizes the voltage through the Zener diode, then flows through the conducting MOS transistor Q2 to the load, and finally flows back to the negative terminal of the power supply.

[0045] During the steady-state maintenance phase, after MOS transistor Q2 turns on, the gate voltage remains stable. As long as the pump drive control signal continues to act on the base of transistor Q1, MOS transistor Q2 will remain on. The Zener diode continuously limits the voltage during this process, ensuring the safe operation of the circuit components.

[0046] During shutdown, when the pump drive control signal disappears or becomes low, the base of transistor Q1 is pulled low, turning off transistor Q1. No current flows to the gate of MOS transistor Q2. The back electromotive force generated by the pump motor is dissipated through the discharge circuit formed by the external diode.

[0047] In standby mode, after MOS tube Q2 is turned off, the circuit returns to its initial state and waits for the next water pump drive control signal. In the entire process, it can be considered that the set voltage regulator diode and transistor Q1 play a key protection and driving role.

[0048] In a specific application, the second terminal of the water supply equipment is connected to VCC_GS, which is the motor current collection point of the water pump. It is connected to the differential amplifier circuit for voltage amplification processing and then sent to the water supply main control module for processing.

[0049] In some embodiments, the water supply equipment circuit also includes a manual control circuit, which includes a manual control switch. The input end of the manual control switch is connected to the power input, and the output end is connected to the water pump drive circuit, which is used to manually drive the water supply equipment to supply water to the robot body of the cleaning robot after the manual control switch is manually triggered.

[0050] A new manual control circuit provides a backup control method in case the remote control device circuit fails or remote control is unavailable. The manual control switch allows the operator to directly and physically start and stop the water pump. The input of the manual control switch is connected to the power input, and the output is connected to the water pump drive circuit. When the manual control switch is triggered, power flows through the switch to the water pump drive circuit. Upon receiving the signal from the manual control switch, the water pump drive circuit activates the water pump, supplying water to the cleaning robot to clean the solar panels.

[0051] The benefit of this embodiment is that a dual control mechanism of remote control and manual operation is provided, which increases the flexibility and reliability of the water supply equipment control system. In the event that the remote control fails or is inconvenient to use, manual control can be used as an emergency measure to ensure that the cleaning work can continue.

[0052] As an example, a water supply control system for a solar panel cleaning robot includes the following components: a remote control unit, including a handheld remote controller with buttons for starting, stopping, and adjusting the water supply; a water supply circuit, including an integrated water pump system and a wireless module for communicating with the remote controller; and a manual control circuit, including a clearly labeled manual control switch, mounted within easy reach of the cleaning robot. In practical applications, the operator can initially control the robot's water supply using the remote controller. If the remote controller battery dies or a communication failure occurs, the operator can simply walk to the water supply unit, rather than to the robot itself, to easily control the water supply using the manual control switch, ensuring that the cleaning process is not interrupted by minor technical issues. The manual control switch can be designed to be waterproof for outdoor use. This ensures continuous and reliable cleaning operations, making it ideal for use in solar panel cleaning environments.

[0053] In some embodiments, the water supply equipment circuit also includes a display module, which is electrically connected to the water supply main control module and is used to indicate the working status of the water supply equipment. The working status includes one or more of the power supply status, water supply status, and communication status of the water supply equipment.

[0054] The display module is responsible for providing the operator with real-time information on the operating status of the water supply unit. It is electrically connected to the main water supply control module and receives status signals from the module. The display module displays the power supply status, water supply status, and communication status of the water supply unit. The power supply status indicates whether the unit is connected to a power source (with batteries installed). The water supply status indicates whether the pump is operating and / or whether water flow is normal. The communication status indicates whether the water supply unit has successfully established communication with the remote control device.

[0055] The benefit of this embodiment is that the display module allows the operator to intuitively understand the operating status of the water supply equipment, improving operational transparency. The real-time status display helps quickly identify and resolve potential problems that may arise during the water supply process. The display module allows the operator to more intuitively understand the equipment status, improving operational convenience and satisfaction.

[0056] In specific applications, the display module, as part of the water supply equipment circuit, can be implemented in the form of LED (light-emitting diode) lights. For example, multiple groups of LED lights with different colors can be used to indicate different operating states. For example, within the same group of LED lights, a green LED indicates normal operation, a red LED indicates an error or fault state, and a yellow LED indicates a warning or maintenance state. LED lights can also be used to indicate power supply status. When the power is turned on, the LED lights light up, indicating that the power supply is normal. Alternatively, the operating status of the water pump can be indicated by flashing or continuously lighting the LED light. For example, a continuous light indicates that the water pump is running, while a flashing light indicates that the water flow rate is low or the water pump is about to stop. For example, LED lights can be used to indicate communication status, such as normal communication or communication interruption.

[0057] As an example, unlike the previous example, a display screen installed in a prominent location on the water supply equipment includes the following display areas and displays the following information: a power indicator display area, where a green LED lights up to indicate normal power supply and a red LED lights up to indicate a power failure. A pump status display area, which displays the operating status of the water pump, such as "Running" or "Stopped." A communication indicator display area, which displays the communication status with the remote control device, such as "Communication Normal" or "Communication Fault."

[0058] In some embodiments, the water supply equipment control system also includes a power processing module, which is arranged between the power input of the water supply equipment and the water supply main control module, and is used to power the water supply main control module and provide power supply voltage for the water pump drive circuit.

[0059] The power processing module is located between the power input terminal of the water supply equipment and the water supply main control module. It can include a voltage converter to convert the voltage of the input power supply to the voltage level required by the water supply main control module. The input power supply can be, for example, a battery. The power processing module can also include a power stabilization module and a power protection module.

[0060] The power stabilization module, for example, includes a voltage stabilization circuit that uses a Zener diode, a voltage regulator tube, or an integrated voltage regulator chip to maintain a stable output voltage even if the input voltage or load changes. The power protection module can use current sensing circuits and protection components (such as fuses, circuit breakers, or MOSFETs) to prevent excessive current from flowing through the system, while using varistors and transient voltage suppressor diodes (TVSDiods) to prevent voltage from exceeding safety thresholds.

[0061] The power processing module converts the battery's output voltage to the voltage level required by the water supply main control module. For example, if the battery provides 12V DC power and the main control module requires 5V, a step-down converter in the power processing module is required to reduce the voltage. The power processing module also provides electrical isolation, preventing direct electrical connection between the battery and the main control module.

[0062] The advantage of this embodiment is that the power processing module allows the water supply equipment to use batteries of different voltage levels, increasing the flexibility of power supply selection. The protection function of the power processing module reduces the risk of damage to the main control module.

[0063] See also Figure 3 , an embodiment of the present application further provides a cleaning robot, the cleaning robot comprising: a robot body provided with a nozzle, and a water supply device provided separately from the robot body, wherein a water inlet end of the water supply device is connected to a water inlet pipe, and a water outlet end of the water supply device is connected to a water supply end of the robot body via a water pipe of a water pipe truck and is connected to the nozzle through a pipe;

[0064] It also includes the water supply equipment control system described in any of the above embodiments.

[0065] The robot body is equipped with nozzles for cleaning tasks. The water supply system is separate from the robot body, allowing for independent operation and maintenance, increasing the cleaning robot's flexibility. The water supply system's water inlet is connected to the water inlet pipe, which draws water from the source; the water outlet is connected to the robot body via a water pipe to ensure water supply. A water hose cart, a mobile water pipe device, connects the water outlet of the water supply system to the water supply of the robot body via a water pipe, providing the necessary access. The nozzles are used to perform and complete the cleaning process. The separation of the water supply system from the robot body provides greater modularity, facilitating independent upgrades or maintenance. The use of a water hose cart increases the flexibility of the cleaning robot's cleaning process, allowing the robot to perform cleaning operations in different locations.

[0066] The advantage of this embodiment is that the separation of the water supply device and the robot body provides a modular option, which is convenient for upgrading or maintaining each separately. The separate design makes it easier to maintain the water supply device and the robot body, without having to disassemble the entire system every time.

[0068] The water supply equipment includes an outer shell and a water pump. The water supply equipment circuit of the water supply equipment control system is arranged in the outer shell and controls the water pump to supply water to the sprinkler head.

[0069] The remote control device circuit can be considered as being built into the remote control, responsible for receiving the operator's input commands and converting these commands into wireless signals and sending them to the water supply device. The water supply device receives the control signal from the remote control and activates the water supply device.

[0070] The water supply system consists of an outer shell and a water pump. The outer shell houses the water supply circuit, which controls the pump's operation. The pump, acting on the circuit's instructions, draws water from the source and delivers it to the sprinkler through a pipeline.

[0071] The advantage of this embodiment is that the use of the remote control allows the operator to remotely control the water supply of the cleaning robot, thereby improving the convenience of operation. Through the remote control device circuit, the operator can control the start and stop of the water supply device and the adjustment of the water pressure and flow in real time.
