According to GJB2035-95 “helicopter transmission system general specification” requirements,helicopter transmission system developments need plenty of test-beds to perform test validating its design. Through the summary of the traditional test bed measurement and control system construction experience,on the basis of meet the technical indicators of the transmission system test-bed,using distributed structure and C/S model measurement and control network,designed a universality measurement and control system,to meet the different scale structure, test type and test method of the test bench construction tasks. The structure and working principle of the measurement and control system are described,the communication process and program implementation method of field device layer, data server layer and client layer are introduced in detail. The system improves the test efficiency and measurement and control precision on the basis of satisfying the real-time and reliability, reduces the cycle and the difficulty in the aspects of the construction and adaptability reform about test-bed and strengthens the flexibility and maintainability of the test-bed.The system is successfully applied to several transmission test-beds with stable and reliable operation.
