The unmanned sprinkler truck is an intelligent sanitation vehicle designed to perform road cleaning, dust suppression, and watering operations without an onboard driver. It combines traditional sprinkling functions with advanced automation, sensing, and remote-control technologies to improve safety, efficiency, and flexibility in urban and industrial environments.Structurally, the vehicle consists of a water tank, high‑pressure pumps, sprinkler nozzles, a chassis, an autonomous driving system, and communication modules. The nozzles are typically mounted at the front, rear, and sides, allowing multiple working modes such as front flushing, rear sprinkling, side spraying, and wide-area misting. The water volume and pressure can be precisely adjusted according to different scenarios, including city streets, construction sites, industrial parks, and logistics hubs.The core feature of the unmanned sprinkler truck is its autonomous driving and operation capability. Using lidar, cameras, ultrasonic sensors, GPS, and inertial navigation units, the vehicle can perceive lanes, obstacles, pedestrians, and surrounding traffic conditions in real time. Based on this perception, an onboard computer plans routes, adjusts speed, and executes turning and braking actions automatically. High-precision positioning allows the truck to follow pre‑planned routes with minimal deviation, ensuring that designated roads or zones are covered evenly and repeatedly.In addition to fully autonomous modes, the vehicle usually supports remote monitoring and teleoperation. Operators can supervise its status, view live video streams, and issue commands from a control center. This reduces the need for personnel to work in hazardous environments such as high‑temperature industrial areas, dusty construction zones, or regions affected by chemical leaks and fires. In emergency situations, the unmanned sprinkler truck can be dispatched quickly for cooling, dust suppression, or simple decontamination tasks without exposing personnel to direct danger.Energy systems may vary, with some models using traditional fuel engines and others adopting electric or hybrid powertrains to reduce emissions and noise. Intelligent control of pumps and water distribution helps minimize water waste, and route-optimization algorithms reduce unnecessary mileage and energy consumption. When integrated with a city’s smart management platform, the vehicle can receive task schedules automatically, report operation data, and support big‑data analysis for maintenance planning and resource allocation.Overall, the unmanned sprinkler truck represents an important step in the modernization and automation of urban sanitation and industrial support services. By combining autonomous driving, precision sprinkling, remote control, and smart scheduling, it enhances operational safety, reduces labor intensity, and contributes to more sustainable and efficient environmental management.
