Description

Technical Field

[0001] This utility model relates to a car body cleaning device, and more particularly to a fully automatic cleaning device for cleaning the body of a bus. Background Technology

[0002] In urban public transport operations, to provide city residents with a pleasant riding environment, bus companies require all operating vehicles to be kept clean, hygienic, and disinfected, both inside and out. To achieve this, car wash areas are set up in the bus company's parking lots, staffed with cleaning personnel. Buses must return to the car wash area for cleaning after rain or after a period of operation. Current methods primarily involve manual high-pressure water jet washing followed by hand-held brush cleaning, a time-consuming and labor-intensive process that wastes significant amounts of water and pollutes the wash area. Semi-automatic mobile car wash equipment has also been developed, which can be manually operated... The manually pulled car wash cart is equipped with a gantry frame, a washing roller brush in the middle of the gantry frame, and spray nozzles on the gantry columns. During washing, the cart is manually moved next to the vehicle, and the spray nozzles and roller brush are activated to spray water onto the vehicle. The roller brush begins to roll, and the cart is manually moved to clean a specific surface of the vehicle. However, to wash the entire vehicle, the car wash machine needs to be manually pulled around the vehicle. Maintaining a safe distance between the car wash machine and the vehicle body is difficult during turns, and the operation is strenuous, time-consuming, and ineffective. This makes it unsuitable for washing large numbers of buses. Therefore, developing a fully automatic and intelligent car wash system to improve efficiency is a problem that needs to be solved on-site. Summary of the Invention

This invention employs an automated guided vehicle (AGV) navigation method. Its working principle is mainly to obtain the vehicle's own position information by measuring the magnetic field signal along the path, thereby realizing vehicle control and navigation. The magnetic strip navigation system typically includes a magnetic strip, a magnetic navigation sensor, and a control system. The magnetic strip is laid on the ground as a reference path for navigation; the magnetic navigation sensor is installed at the bottom of the AGV and can detect changes in the magnetic field above the magnetic strip; when the AGV travels along the magnetic strip, the magnetic field... The navigation sensor continuously collects magnetic field signals and sends these signals to the control system. By analyzing the intensity and distribution of the magnetic field signals, the control system calculates the positional deviation of the AGV relative to the magnetic strip. Based on this deviation, the control system adjusts the AGV's travel direction to ensure it travels accurately along the magnetic strip path.
