Abstract:According to the complexity of new vehicle’s ultra-short-wave carrier radio’s principle and structure, the height of the rate of false alarm, the difficulty of fault location, adopting technology of embedded-system, software of database and circuit intelligent detection, develop the new on-board maintenance system of ultra-short-wave of radio with the hardware platform of maintenance test computer and measurement fixture. The new maintenance system can accomplish assessment and fault location of the radio, real-time information storage and inquiry, with carrying out property detection on ultra-short-wave carrier radio and its internal modular automatically. The new maintenance system can solve the problem of lack of maintenance’s methods and the difficulty of guarantee of the Army vehicle ’s ultra-short- wave carrier radio.
