Abstract

The invention discloses an MVB (multifunction vehicle bus) analysis device comprising an interface conversion module, an FPGA module, an STM32 microcontroller chip and a serial port communication module. The STM32 microcontroller chip is used for acquiring and encoding data to be transmitted and transmitting the data to be transmitted, to an MVB through the port conversion module. The FPGA module is further used for acquiring data frames which are transmitted in the MVB, and transforming the format. The STM32 microcontroller chip is further used for decoding the acquired data frames and transmitting the decoded data frames to an upper computer. The MVB analysis device has the advantages that monitoring response data frames of equipment on the MVB is achieved, multiple MVB devices can be automatically monitored in real time, faults of the MVB devices can be found quickly, and the efficiency in monitoring MVB devices can be greatly improved.

Description

technical field [0001] The invention relates to an MVB bus analyzing device. Background technique [0002] The MVB bus is a multi-function vehicle bus, which is a serial data communication bus mainly used (but not exclusively) for interconnected devices requiring interoperability and interchangeability. MVB bus is a communication bus protocol mainly used in modern rail transit vehicles. Due to the increase of subway MVB equipment, the monitoring of MVB equipment is becoming more and more important for the normal operation of modern rail transit vehicles. At the same time, for the detection of MVB devices, it is still necessary to manually detect the MVB devices one by one to determine whether each MVB device is working normally, which requires a lot of manpower and material resources, and the detection efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects that the monitoring of MVB dev...
