Abstract:Differing from work logic of traditional vehicles, it is a new trend to design a data acquisition and transmission system which can satisfy the characteristic of green vehicles. Using Samsung S3C6410 as main control chip, a general data acquisition and transmission system is designed, and providing the corresponding wireless data acquisition, transmission and status monitoring system. In the data center, programs running on the servers can effectively monitor vehicles, through analysis and storage of collected data. By collecting and analyzing the huge vehicles data, it can be used to realize the functions such as vehicle parameters optimization and fault diagnosis.
