【Abstract】 Compared with other data acquisition system based on ISA,PCI,PXI bus,more advantages are provided when the system is based on VXI bus,which makes it become the chief choice in data acquisition system. This paper researches and develops a testing system based on VXI bus,which is one of the main invested 95 projects in Ministry of Railway and used for the output of the alternating transmission diesel locomotive. The paper mainly discusses the development of the testing system,heavily involved in demonstration of testing system project,select and configuration of transducer and hardware,development of software and the measurement of anti-interference. Running during two year,the testing system is proved high precision and high reliability.更多还原
