Design and Implementation of Polarity Testing System of Contact-less Solenoid Valve Based on Wireless Sensor Networks

Abstract

Abstract Solenoid valves are important control components in industrial production and are used in various aerospace vehicles. In view of the characteristics and requirements of the solenoid valve polarity test of the launch vehicle power system, combined with some current research on magnetic flux leakage detection, and considering the difficulty of operation, a design scheme of a contact-less solenoid valve polarity test system based on Wireless Sensor Networks (WSN) is proposed. The solenoid valve of the launch vehicle was tested and verified. The system organically combines wireless sensor network technology, leakage magnetic field measurement technology, and rapid monitoring and interpretation technology. It has the characteristics of miniaturization, portability and cable-free. The software interface of the test instrument is more concise and beautiful, and it is accurate to the solenoid valve polarity system. Degree, portability, test coverage and user experience have all been significantly improved, which has important reference significance for the application of subsequent wireless test technology in other space vehicle tests.
