Design of a High-End Rain-Detection Line for Passenger Cars

Taking the rain-detection line in an automobile assembly workshop as an example, this paper briefly introduces the composition, working principle, and design principle of the rain-detection line. Chamber, water treatment system, spray pipeline, water blowing system, exhaust system, conveying system and electric control system are included in the composition. The paper also discusses in detail the calculation method of the key parameters of the rain-detection line which including the calculation of the length of the chamber, the rain intensity and rainfall, the calculation of water treatment system and the calculation of exhaust volume. It has a strong reference significance for the design of the rain test line, and also provides a basis for the further improvement of the vehicle rain detection mode.
