Abstract

The invention discloses a wireless networking system and method of working parameters of rail vehicle equipment or mechanism. Short-distance wireless communication is realized based on an ISM (Industrial Scientific Medical) frequency band; a star-like hybrid networking system is formed by using data acqusition node equipment, carriage gathering node equipment and vehicle gateway node equipment; the problems such as packet loss and wireless transmission interruption of data transmission in a carriage are solved; a stable data transmission channel is provided; the system and the method are suitable for transmission of large data volume in a complex environment in an urban rail vehicle and have good application prospect.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a wireless networking system and method for rail vehicle equipment or mechanism working parameters. Background technique [0002] In recent years, with the rapid growth of my country's urban population and national economy, and the country's strong promotion of public transportation construction policies and measures, my country's urban rail transit construction has entered a stage of rapid development. The reliability and safety of various moving equipment in urban rail vehicles (such as bogies, doors, motors, platform screen doors, etc.) is an important factor to ensure the personal safety of passengers. The acquisition and transmission of working status information to the background for data analysis is very important. [0003] At present, the commonly used method to obtain the working status information of the equipment or mechanism system in the rail vehicle is t...
