Technical Field

[0001] The invention relates to the technical field of vehicle washing control, and in particular to a method for controlling and analyzing the omnidirectional washing performance of a minibus. Background Art

[0002] With the improvement of people's living standards, urban buses have gradually become an indispensable means of transportation for people. Therefore, the vehicle service industry, especially the vehicle cleaning industry, has developed rapidly. Among them, channel-type minibus washing equipment is favored because of its advantages such as fast washing speed and continuous washing.

[0003] The channel-type minibus washing equipment generally installs multiple groups of washing stations in the washing channel. The minibus enters from the channel entrance, passes through each group of washing stations in turn for washing, and exits from the channel exit. However, this minibus washing method has the following problems:

[0004] 1. The existing minibus cleaning method uses the same cleaning method for cleaning regardless of the model of the vehicle. This cleaning method is relatively simple and cannot identify the model of the minibus and the degree of dirt on the vehicle surface, so it is impossible to perform digital analysis and processing on the actual situation of the minibus, resulting in the minibus cleaning effect not being ideal, thereby reducing the cleaning performance of the minibus and failing to meet the basic cleaning needs of the corresponding minibus owners to a great extent;

[0005] 2. At present, minibuses need to be scrubbed during the cleaning process, otherwise the minibuses will not be cleaned thoroughly. However, the existing method basically relies on the vehicle's own contour to push and scrub on the cleaning roller.
