Description
Technical Field
[0001] This invention relates to the field of sprinkler truck technology, and in particular to a sprinkler truck water filling and alignment auxiliary device. Background Technology
[0002] A water sprinkler truck is a service vehicle that integrates multiple functions, including spraying and water transport, to suit various usage environments and purposes. Water sprinkler trucks are commonly used in urban roads, large factories, military units, parks, and other organizations for cleaning roads, sanitation, dust control, watering, and spraying pesticides.
[0003] When water trucks are being refilled, drivers need to frequently enter and exit the cab to observe the location of the water inlet. This is especially problematic in inclement weather (such as sandstorms, nighttime, and winter), where obstructed visibility makes alignment difficult, resulting in low work efficiency and safety hazards. Traditional methods rely on manual visual adjustment, requiring drivers to repeatedly move the vehicle for alignment, which is time-consuming and labor-intensive. In winter, splashing water can easily cause personnel to freeze. Visibility is poor at night or in dusty environments, leading to high operational risks. Summary of the Invention
[0004] To address the aforementioned problems, the purpose of this invention is to provide an auxiliary device for water filling and alignment of a sprinkler truck.
[0005] A water filling and alignment auxiliary device for a sprinkler truck includes:
[0006] A camera is used to capture images of the water-filling area;
[0007] The image processing module, which communicates with the camera, is used to analyze the image of the water filling area using a target recognition algorithm to determine the alignment status between the water inlet and the water injection device.
[0008] An angle sensor is used to detect the relative angle between the sprinkler truck body and the water injection equipment;
[0009] The control system is communicatively connected to the image processing module and the angle sensor, and is used to provide adjustment instructions to the driver based on the alignment status of the water inlet and the water injection equipment and the relative angle between the sprinkler truck body and the water injection equipment.
[0010] Preferably, it also includes: a water level sensor, installed inside the water tank of the sprinkler truck, connected to the control system, for real-time monitoring of the water level information in the water tank.
[0011] Preferably, it further includes: a prompting module, which is communicatively connected to the control system, and issues an alarm when the water level in the tank exceeds a set value.
[0012] Preferably, it further includes a display screen, which is communicatively connected to the control system, for displaying images of the water filling area and water level information in the water tank.
[0013] Preferably, the camera is a 360° panoramic camera that is fixed to the rear bracket of the sprinkler truck with bolts.
[0014] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:
[0015] 1. This water-filling alignment auxiliary device for sprinkler trucks integrates a 360° panoramic camera, an image processing module, a display screen, a prompt module, a water level sensor, an angle sensor, and a control system, thereby achieving intelligent assistance in the water-filling process of sprinkler trucks and greatly improving the efficiency and safety of water-filling operations.
[0016] 2. This water truck water filling alignment auxiliary device is equipped with a 360° panoramic camera. The 360° panoramic camera can cover the entire field of view of the water filling area, and is not affected by obstructed vision. It can capture clear images even in bad weather. The wide-angle and high-definition design ensures rich image details, making it easy for the driver to accurately judge the alignment status of the water filling port and the water injection equipment. The camera is fixed to the bracket at the rear of the water truck with bolts, so the installation is stable and not easy to fall off, ensuring the reliability of use.
[0017] 3. This water-filling alignment auxiliary device for sprinkler trucks is equipped with a water level sensor. The water level sensor can monitor the water level changes in the water tank in real time and transmit the water level information to the control system in real time. When the water level reaches the preset safety threshold, the control system will immediately issue an alarm to the driver through the prompt module to avoid water overflow causing waste or safety hazards. At the same time, the driver can reasonably plan the amount of water to be added based on the water level information, thereby improving the accuracy and efficiency of water filling operations.
[0018] 4. This water-filling alignment auxiliary device for sprinkler trucks incorporates an angle sensor. The angle sensor accurately detects the relative angle between the sprinkler truck body and the water injection equipment, transmitting the angle data to the control system in real time. The control system performs comprehensive analysis and calculation based on the received angle data and alignment status information provided by the image processing module, deriving optimal vehicle adjustment instructions. These instructions are displayed to the driver intuitively through a prompt module, such as a graphical interface showing the direction and distance the vehicle should move, or audio prompts. This allows the driver to quickly and accurately adjust the sprinkler truck's position, ensuring precise alignment between the water inlet and the water injection equipment, significantly improving the accuracy and efficiency of water filling operations.

The control system receives data from the image processing module and the angle sensor, calculates adjustment commands based on the alignment and relative angle, and provides operational suggestions to the driver through the prompting module. This ensures accurate alignment between the water inlet and the water injection equipment, improving water filling efficiency and safety. The prompting module clearly marks the optimal alignment position of the water inlet and the water injection equipment, as well as the deviation between the current vehicle position and the target position, on the display screen with bright colors and high-brightness borders, providing a clear view for the driver. The module also emits clear and easily identifiable sound signals, such as voice commands or alarms, to guide the driver in appropriate actions or alert them to potential safety hazards.
[0032] Working principle of the invention:
[0033] When the water truck needs refilling, the driver activates the water filling alignment assist device. A 360° panoramic camera begins capturing a full view of the water filling area. Thanks to its waterproof and dustproof design, the camera can function normally even in harsh weather conditions. The camera's captured images are analyzed in real-time by an image processing module, and an embedded processor runs a target recognition algorithm to identify the alignment status between the water inlet and the water injection equipment. Once the positional relationship between the water inlet and the water injection equipment is identified, the control system receives data from the image processing module and, combined with the relative angle between the water truck body and the water injection equipment detected by the angle sensor, calculates an adjustment command. Subsequently, the control system provides operational suggestions to the driver through a prompt module. The prompt module clearly displays the suggestions to the driver on the screen using audio-visual signals or graphic annotations, guiding the driver to adjust the vehicle's position to ensure accurate alignment between the water inlet and the water injection equipment. During the water filling process, a water level sensor monitors the water level changes in the tank in real time and transmits the water level information to the control system, allowing the driver to monitor the water filling progress at any time. The entire water filling process does not require the driver to frequently enter and exit the cab to observe, greatly improving water filling efficiency and safety.
