Abstract

The invention discloses a bullet train state monitoring system and a multifunctional hybrid gateway thereof. The multifunctional hybrid gateway comprises a field bus communication module, a wireless communication module, an Ethernet communication module, a main controller, a storage circuit and a real-time clock circuit, wherein the main controller is connected with the field bus communication module, the wireless communication module and the Ethernet communication module and used for performing protocol conversion and data processing on interactive data of the field bus communication module, the wireless communication module and the Ethernet communication module. The multifunctional hybrid gateway disclosed by the invention can realize the functions of protocol conversion, network transmission, data fusion and the like, and has the advantages of combining wired transmission with wireless transmission and real-time data transmission with high-capacity data transmission.

Description

technical field [0001] The invention relates to a vehicle running state monitoring system, in particular to an EMU state monitoring system and a multifunctional hybrid gateway thereof, belonging to the technical field of sensors and networks. Background technique [0002] The train set with dispersed power is called the EMU. The EMU status monitoring system is used to monitor the running status and fault signals of the traction drive system, bogie, braking system, air conditioning system, compartment environment, compartment auxiliary and other system components of the whole train. The real-time collection, processing and uploading of data play a vital role in the safe operation of locomotives. [0003] The existing EMUs do not have an independent state monitoring system, and a small amount of state monitoring of some components, such as traction converters, traction motors, etc., is carried out by means of the train communication network (TCN). A wire train bus (WTB for sh...
