Research On Bus Network Based On CAN

Based on a given car type made in Nanjing auto company, this paper studied the car network technology based on CAN bus. The former two chapter of the paper introduced the car network technology, auto electron control and the on-site CAN bus technology; The Third chapter described the hardware design of the system in detail; The forth chapter described the software design of the system; The fifth chapter designed the upstream watch system.Through thorough study on the car network based on CAN bus, the author brought forward the design project described in the paper, and containt senveral faces:(1) Study on various real time communicationg signal, consider electronic components on bus, builder the module of communicationg system.(2) Deeply research CAN protocal, do the hardware design of the system in detail, and design other interface electronic draws(3) Based on CAN capacity node, program the soft design on every node.(4) Research on detail electronic draws on digit signal and analog signal.(5) Research and designed the upstream watch system, monitors the input and output data of system.(6) Summarized the design of soft and handware of CAN system, pointer the opinion on the CAN system and analisys the foregrand of the system.The study can be considered as an exploration on the car network based on CAN bus, and has some instructive meaningful for the practice.
