Abstract: This paper introduces a locomotive failure diagnosis system based on wireless
transmission and single chip microcomputer. The system can control the locomotive electric
circuit intelligent detector via PIC16C74 MCU in order to acquire, process and transmit the
real-time datum of the Resistance, thus, man machine mutual control comes into true in virtue of wireless transmission module PTR2000. Besides, the results of application show that the system is convenient to control and stable to perform, implements reliable wireless data transmission.
