| Storage test system by a variety of sensors, multiple collecting-and-categorizing device,more data recorder, and distribution device component. This thesis research parallel test manyrecorder monitoring technology, on the one hand, the developed test monitoring equipmentcomplete storage test system in the developing process of the function, performance testing;On the other hand read out record flight condition after the flight test data and analysis, faultlocation, provides the basis for failure components for improve or optimize the design.According to mission requirements and technical specifications of the storage test system,and function of the monitoring stations in the storage test system, propose the overall designof the monitoring station achieving parallel test. Analysis of the characteristics of the datatransfer interface，design independent of each other communication interface，transferinstructions and data to the RS-422 asynchronous serial mode，to ensure that each channeldoes not interfere with in parallel the testing process. By researching on long-termtransmission interference suppression techniques，adjust the decoding level sampling initialtime，to avoid signal the phenomenon of competition and adventure，ensure the accuracy ofthe long-term transmission data. By comparative optical fiber, coaxial, twisted pair, threetransmission media, combined with requirements of the storage test system data transmissionphysical layer transmission medium, use twisted pair as transmission medium. For thecharacteristics of the parallel test, design data, instructions communication the agreedagreements, stipulated in the agreement, the frame format for transmission of data andcommunication instruction frame flag to protect the communication is correct.Through the research of the monitoring equipment to test performance testing andfunction, system test, the test results are given, and the results show that the developed testmonitoring equipment to meet the design requirements. |
