AI Technical Summary
When operating a traditional sprinkler truck, the driver needs to manually control the watering distance, which distracts attention and poses a driving safety hazard. In addition, existing visual recognition technology cannot achieve independent adjustment of the watering width on the left and right sides, resulting in uneven cleaning effects.
An AI camera module is used to identify the width of the road on both sides and the distance between pedestrians on the left and right sides of the vehicle. After processing by the control unit, the speed of the left and right sprinkler actuators is controlled respectively to achieve intelligent adjustment of the left and right sprinkler widths.
It improves the efficiency and accuracy of watering operations, reduces water waste, ensures road cleaning effects, and prevents pedestrians on the roadside from being splashed with sewage, thereby improving driving safety.

Abstract
Description
Technical Field
[0001] The present invention relates to a sprinkler truck control device, in particular to an intelligent sprinkler truck control device based on curbstone distance recognition. Background Art
[0002] Sprinkler trucks are used to flush dirt from the center of the road to the edge, where they are then vacuumed by a sweeper into a wastewater tank for transfer to a waste disposal station. Traditionally, sprinkler trucks control the spraying distance by adjusting the motor speed via controls in the cab. This approach distracts the driver and poses a safety hazard.
[0003] Currently, the industry has introduced technologies based on visual recognition, with two technical approaches. The first method uses the identification of pedestrians and closes the sprinkler valve. While this solution protects pedestrians, the closure of the sprinkler valve does not guarantee the cleanliness of the road surface. Another solution is to proactively adjust the water pump speed after the vehicle recognizes pedestrians, reducing the width of the sprinkler. However, because these vehicles only use a single pump to drive two valves on the left and right sides, the water spray width is reduced simultaneously when the pump speed is reduced, significantly reducing the cleaning effect on the side without pedestrians. Therefore, there is an urgent need for an intelligent control system that can intelligently identify the distance to the curb and independently adjust the sprinkler width on the left and right sides. Summary of the Invention
[0004] In response to the problems existing in the above-mentioned prior art, the present invention provides an intelligent sprinkler truck control device based on curbstone distance recognition to improve the efficiency and accuracy of watering operations, reduce water resource waste, and reduce the impact of operations on roadside pedestrians.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is: an intelligent sprinkler truck control device based on curbstone distance recognition, comprising: AI camera module: used to identify the width of both sides of the road and the distance between pedestrians on the left and right sides of the vehicle, and send them to the control unit for processing; Sprinkler actuator: used to sprinkle water on the road surface; User operation interface: It is the interface of the input device of the control unit, used to input control instructions to the control unit: Control unit: used to process the information sent by the AI camera module and the control information of the user operation interface. The control unit processes and controls the operation of the sprinkler actuator.
[0006] Furthermore, the AI camera module is equipped with three AI cameras, namely a front AI camera installed at the front of the vehicle, a right AI camera installed on the right side of the vehicle body, and a left AI camera installed on the left side of the vehicle body.
[0007] Furthermore, the front AI camera is used to identify the width of the left and right sides of the road, and the right AI camera and the left AI camera are used to identify the width of pedestrians on the left and right sides of the vehicle from the vehicle. The front AI camera, the right AI camera, and the left AI camera will collect the width information in real time and send it to the control unit in a continuous loop.
[0008] Furthermore, the sprinkler actuator includes a right three-bend hedge sprinkler pump, a right three-bend hedge sprinkler pump drive motor, a right three-bend hedge, a left three-bend hedge sprinkler pump drive motor, a left three-bend hedge sprinkler pump, a left three-bend hedge, and a water pipeline. The input end of the water pipeline is connected to the vehicle-mounted water tank. The left output pipeline of the water pipeline is provided with a left three-bend hedge sprinkler pump. The left three-bend hedge is installed at the output end of the left output pipeline. The right output pipeline of the water pipeline is provided with a right three-bend hedge sprinkler pump. The right three-bend hedge is installed at the output end of the right output pipeline. The right three-bend hedge sprinkler pump drive motor is installed on the right three-bend hedge sprinkler pump for controlling the rotation of the right three-bend hedge sprinkler pump. The left three-bend hedge sprinkler pump drive motor is installed on the left three-bend hedge sprinkler pump for controlling the rotation of the left three-bend hedge sprinkler pump. The water sprayed by the left three-bend hedge washes the road on the right side, and the water sprayed by the right three-bend hedge washes the road on the left side.
[0009] Furthermore, the left three-bend hedge sprinkler pump drive motor and the right three-bend hedge sprinkler pump drive motor are both connected to the output end of the control unit. After receiving the speed instruction from the control unit, the left three-bend hedge sprinkler pump drive motor and the right three-bend hedge sprinkler pump drive motor adjust the water pump speed, thereby adjusting the left three-bend hedge and right three-bend hedge sprinkler width, ensuring that no matter where the vehicle is on the roadside, the left and right sprinkler widths can be intelligently adjusted to ensure the road cleaning effect and avoid pedestrians on the roadside from being splashed with sewage.
[0010] Furthermore, the user operation interface includes an operation start button, a button to enter the intelligent sprinkler mode, a left three-bend hedge sprinkler pump drive motor speed adjustment button, and a right three-bend hedge sprinkler pump drive motor speed adjustment button; the user operation interface provides users with two operation modes, namely manual mode and automatic mode; customers can freely choose to manually adjust the sprinkler width, or let the intelligent sprinkler system adaptively adjust it to avoid the situation where vehicle operations are affected when the AI camera module fails.
[0011] Furthermore, the control unit includes: a controller, which performs real-time CAN communication with the AI camera module and calculates the collected signals. The controller updates the left road width, right road width, left pedestrian distance, and right pedestrian distance in real time as the vehicle travels; at the same time, the control unit transmits the required speeds of the left three-turn hedge sprinkler pump and the right three-turn hedge sprinkler pump to the corresponding left three-turn hedge sprinkler pump drive motor and right three-turn hedge sprinkler pump drive motor respectively.
[0012] Furthermore, after receiving the distance information sent by the AI camera module, the controller calculates the speed of the left three-turn hedge sprinkler pump and the right three-turn hedge sprinkler pump according to the left and right road widths; and sends the speed to the left three-turn hedge sprinkler pump drive motor and the right three-turn hedge sprinkler pump drive motor through the CAN bus; the left three-turn hedge sprinkler pump drive motor and the right three-turn hedge sprinkler pump drive motor execute the corresponding speed after receiving the speed information; even if the road width changes and the vehicle position changes, the sprinkler width can also be adaptively adjusted.
[0013] The beneficial effects of the present invention are: the width of the water column sprayed by the sprinkler actuator is adjusted in real time according to the road conditions, the driver can concentrate on driving without worrying about the operation effect; the operation efficiency and driving safety are improved, and water resources are saved.
