The development of DSP has greatly promoted precision and intelligence of industry instrument. This paper introduces a kind of diesel valve diagnoses instrument based on Dual-MCU, TMS320C31 and AT89C52. The instrument measures vibration signal of diesel cylinder header, extracts the characteristic parameters, diagnoses fault of leakage and abnormal clearance of valve. This paper deals in detail with the general structure and function of every part of the diagnosis instrument as well as the structure and design of software for diagnosis.
