[0031] In order to solve the problem of high energy consumption caused by inaccurate or untimely gear switching in the sprinkler truck in the related art, firstly, referring to Figure 1 An embodiment of the present application provides an energy-saving control device for a sprinkler truck, which is suitable for a sprinkler truck. The sprinkler truck includes a water tank 100 and a drive motor 200 for controlling the operating state of the entire vehicle. The energy-saving control device for the sprinkler truck includes a vehicle load monitoring component, a multi-state switch, and a switch control component arranged on the sprinkler truck. The vehicle load monitoring component is used to monitor the liquid level of the water tank 100 in real time and determine the current load of the sprinkler truck based on the liquid level; the multi-state switch includes multiple gears, and the multi-state switch is connected to the drive motor 200; the input end of the switch control component is connected to the output end of the vehicle load monitoring component, and the output end of the switch control component is connected to the multi-state switch. The switch control component is used to determine the current gear according to the current load to control the current operating state of the drive motor 200.
[0032] The multi-state switch is a switch that can automatically or manually select different operating states or power outputs through different gear settings. In this embodiment, the multi-state switch is used to adjust the power output of the sprinkler truck based on the vehicle's operating requirements and / or the liquid level in the water tank 100, that is, to adjust the operating state of the drive motor 200 to achieve energy savings. Adjusting the operating state of the drive motor 200 primarily involves adjusting the torque of the drive motor 200. Furthermore, for the convenience of the driver or worker, manual gear adjustment is also possible. The multi-state switch is located in the cab of the sprinkler truck and includes at least three gears.
[0033] Specifically, the vehicle load monitoring component detects the liquid level in the water tank 100 in real time, and determines the current load of the sprinkler truck based on the liquid level, and then transmits the current load data to the switch control component. The switch control component then determines the current gear position of the multi-state switch based on the current load data, and compares whether the current gear position has changed. If it has changed, the multi-state switch is controlled to switch to the current gear position; if the current gear position has not changed, there is no need to control the multi-state switch to switch.
[0034] The energy-saving control device for the sprinkler truck in this embodiment can automatically switch the gear of the multi-state switch according to the remaining water amount in the water tank 100 of the sprinkler truck through the cooperation of the vehicle load monitoring component, the multi-state switch and the switch control component, so as to realize automatic adjustment of the operating state of the drive motor 200, thereby avoiding the problems of inaccurate manual selection of gears, untimely gear changes, and forgetting to change gears, thereby reducing the energy consumption of the sprinkler truck and being beneficial to energy saving and environmental protection.
[0035] Reference Figure 1 In some embodiments, the vehicle load monitoring component includes a liquid level sensor 300 and a load calculation module. The liquid level sensor 300 is arranged in the water tank 100. The liquid level sensor 300 is used to monitor the liquid level in the water tank 100 in real time and output a corresponding liquid level signal; the load calculation module is connected to the liquid level sensor 300. The load calculation module is used to receive the liquid level signal in real time and determine the current remaining water volume in the water tank 100 based on the liquid level signal, so as to determine the current load of the sprinkler truck based on the remaining water volume.
[0036] Among them, the liquid level sensor 300 in this embodiment is a float-type liquid level sensor 300. This sensor uses a float to move up and down on the liquid surface as the liquid level changes. The displacement of the float is converted into an electrical signal through mechanical or electronic means, thereby monitoring the liquid level height in real time; or it is a pressure-type liquid level sensor 300. This sensor uses the liquid pressure at the bottom of the water tank 100 to judge the liquid level. The higher the water level, the greater the pressure at the bottom. The sensor converts this pressure into an electrical signal and then calculates the liquid level; or it is an ultrasonic liquid level sensor 300. This sensor calculates the liquid level height by the time it takes for an ultrasonic pulse to be emitted from the sensor to the liquid surface and then reflected back to the sensor. However, the liquid level sensor 300 in this embodiment includes but is not limited to the above-mentioned types, as long as it can achieve real-time and accurate monitoring of the liquid level in the water tank 100.
[0037] The liquid level signal is a digital signal representing the percentage of remaining water volume, or a position signal representing the water level. When the liquid level signal is a digital signal representing the percentage of remaining water volume, the liquid level sensor 300 converts the measured liquid level information into a digital signal ranging from 0 to 100, representing the remaining water volume in the water tank 100. For example, 0% indicates that the water tank 100 is empty, and 100% indicates that the water tank 100 is full. This representation is concise and intuitive, easy to understand and operate, and is particularly suitable for applications that require quick access to water volume information. When the liquid level signal is a position signal representing the water level, the sensor may output a position signal indicating that the liquid level is at a specific height (such as low, medium, or high), or a specific voltage value (0V to a certain maximum voltage) to represent different liquid levels. The load calculation module is a chip loaded with a load calculation program. The load calculation module can be installed on the liquid level sensor 300 or on the switch control component.
[0038] Specifically, after receiving the liquid level signal from the liquid level sensor 300 , the load calculation module converts the liquid level signal into the remaining water volume or the corresponding load value through a preset algorithm or model.
[0039] In this embodiment, the current load data of the sprinkler truck can be quickly obtained through the cooperation of the liquid level sensor 300 and the load calculation module, which has a simple structure and good timeliness.
[0040] In some embodiments, the load calculation module is used to determine the current load of the sprinkler truck based on a mapping relationship between a preset water volume and vehicle load and the remaining water volume.
[0041] Among them, the mapping relationship between the preset water volume and the vehicle load can be obtained based on multiple tests. Specifically, it can be determined based on the design parameters of the vehicle and the parameters of the water tank 100. In this embodiment, the mapping relationship between the preset water volume and the vehicle load is a mapping relationship table between the preset water volume and the vehicle load.
[0042] Specifically, after the remaining water volume is obtained, the corresponding vehicle load data may be searched and determined according to a preset mapping relationship table between the water volume and the vehicle load.
[0043] In this embodiment, the current load of the sprinkler truck is determined based on the mapping relationship between the preset water volume and vehicle load and the remaining water volume, which can ensure the efficiency and accuracy of the current load calculation, thereby ensuring the timeliness and accuracy of the gear determination, and further avoiding the problems of inaccurate manual gear selection or untimely gear change and forgetting to change the gear.
[0044] Reference Figure 1 In some embodiments, the state switch control component includes a vehicle controller 400, an input end of the vehicle controller 400 is connected to an output end of the load calculation module, and an output end of the vehicle controller 400 is connected to the multi-state switch.
[0045] Specifically, the vehicle controller 400, as a central control system, can uniformly process data from the liquid level sensor 300 and the load calculation module, perform complex calculations and logical judgments, and by fully understanding the load status of the vehicle, it can intelligently adjust the multi-state switch according to the current working conditions (such as road conditions, load, operating requirements, etc.) to achieve optimal power output and energy saving effects.
[0046] In some embodiments, the vehicle controller 400 is further configured to determine the current torque of the drive motor 200 based on a preset mapping relationship between load and motor torque and the current load, so as to switch the multi-state switch to a gear corresponding to the current torque.
[0047] Among them, the mapping relationship between the preset load and the motor output torque can be obtained based on multiple test data and standard performance predictions. This mapping relationship can effectively describe the torque output required by the motor under different loads to ensure the optimization of vehicle performance.
[0048] Specifically, if the change in the remaining water amount in the water tank 100 causes the current load to change, the vehicle controller 400 will calculate the corresponding motor torque output according to the new load to ensure that the sprinkler truck runs smoothly under different load conditions.
[0049] In this embodiment, the current torque of the drive motor 200 is determined based on the mapping relationship between the preset load and the motor torque and the current load, so that the multi-state switch is switched to the gear corresponding to the current torque. This can ensure that the vehicle responds quickly under different working conditions, improve the working efficiency of the entire system, and reduce the response time; it can also optimize power distribution and avoid unnecessary energy consumption, thereby achieving energy saving purposes; in addition, it can also ensure that under different load conditions, the motor output remains within a safe range, prevent problems such as overload or overheating, and improve the safety and reliability of the vehicle.
[0050] Reference Figure 1 In some embodiments, a cancel switch 500 is further provided on the multi-state switch, and the cancel switch 500 is used to control the on-off between the multi-state switch and the switch control element.
[0051] Among them, one of the main purposes of setting the cancel switch 500 on the multi-state switch is to be able to conveniently cancel the intelligent state and perform manual operation under special circumstances.
[0052] Specifically, when a failure or abnormality occurs in the intelligent control system, the cancellation switch 500 allows the driver to quickly switch to manual mode to avoid operational interruption or dangerous situations caused by system failure; in addition, in emergency situations (such as sudden changes in traffic conditions, equipment failure, etc.), the driver can immediately take over control by canceling the switch 500 to ensure vehicle safety and operational continuity.
[0053] In some embodiments, the cancel switch 500 is a self-resetting switch or a rocker switch.
[0054] Specifically, self-resetting switches and rocker switches are usually designed to be operated with only slight force, ensuring that the driver can react quickly in an emergency and switch to manual mode; in addition, the self-resetting switch will automatically return to its original position after operation, without the driver having to hold it down continuously, reducing operator fatigue and improving operating efficiency.
[0055] The energy-saving control device for the sprinkler truck in the present application can automatically switch the gear of the multi-state switch according to the remaining water amount in the water tank 100 of the sprinkler truck through the cooperation of the vehicle load monitoring component, the multi-state switch and the switch control component, so as to realize automatic adjustment of the operating state of the drive motor 200, thereby avoiding the problems of inaccurate manual selection of gears, untimely gear changes, and forgetting to change gears, thereby reducing the energy consumption of the sprinkler truck and being beneficial to energy saving and environmental protection.

The sprinkler truck also includes a water tank 100 and a drive motor 200, and the drive motor 200 is used to control the operating status of the entire vehicle.
[0057] In addition, refer to Figure 1 The sprinkler truck also includes a combination meter 600, which is connected to the vehicle load monitoring component and the switch control component. The combination meter 600 is used to display the remaining water amount in the water tank 100 and the current gear information of the sprinkler truck.
[0058] Specifically, the combined instrument 600 allows the driver to timely grasp the remaining water volume and current gear information of the sprinkler truck so that the driver can react and operate in time when encountering special situations or emergencies, thereby ensuring driving safety.
[0059] The sprinkler truck in the present application, after being equipped with any one of the energy-saving control devices for sprinkler trucks provided in the first aspect above, is also correspondingly equipped with a vehicle load monitoring component, a multi-state switch and a switch control component, which can realize automatic switching of the gear of the multi-state switch according to the remaining water amount in the water tank 100 of the sprinkler truck, so as to realize automatic adjustment of the operating state of the drive motor 200, thereby avoiding the problems of inaccurate manual selection of gears, untimely gear changes and forgetting to change gears, thereby reducing the energy consumption of the sprinkler truck and achieving the technical effect of energy saving and environmental protection.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
