Design And Implementation Of LIN Bus Analyzer Based On WirelessUSB

With the development of automotive electronics and microprocessor technology, in-vehicle network technology matures, and harness constraints are becoming increasingly obvious. The introduce of Wireless network technology in the in-vehicle network applications solves the problem, and provides better scalability and flexibility.This paper analyzes the development of the in-vehicle local interconnect network and WirelessUSB network. In view of the disadvantage of current LIN development tools, the system design program of LIN Bus Analyzer is advanced, which is based on the system requirements. Firstly, the hardware system architecture and a detailed description of PSoC and WirelessUSB characteristics are introduced. Secondly, the system software framework and the design and implementation of the Bus Monitor terminals, bridges mainframe and PC-software are given in details.This paper focuses on the analysis and implementation of the latest LIN protocol specification LIN2.1 data link layer and transport layer protocol, and proposes the WirelessUSB network architecture design, the wireless network characteristics, workflow and work mode on the basis of the Wireless networks coexistence and interference characteristics and the action model.
