The Research And Development Of Monitor Data Record Test System

With the rapid development of space industry and the frequent firing of aerocraft, it is important to design a kind of reliable and effective test system to ensure the reliable firing and even running of aerocraft. Monitor Record Test System has been as the most important test measure in space aerocraft test for its micromation,high-speed,resistance to overload,resistance to impact and real-time, which provide important reference for the research and development of aerocraft,firing,flight experiment and the final approved product.Firstly,integrated design of Monitor Record Test System was discussed in this paper, which is designed by the principle of memory and test system and top-down system, and the operation mode and flow of the system,the lectotype of key device by capacity calculation and performance analysis were also in this paper. Secondly, the paper introduced the composition principle,workflow,hardware circuits design and the sequential design of key device, put forward the idea of real-time monitor, and adopt the technology of sample real- real-time monitor and mixed coding to achieve the synchronization of monitor and data record; it presented the thought of"independent"in memory design, which improved the reliability of memory greatly. Thirdly, the design thought of test flat, and its composition principle,workflow were introduced, and the key technology of the programmed signal source and long-distance transmission were gone deep in to one by one.The experimental data of the system test was discussed in the conclusion; it has been proved the Monitor Data Record Test System can test the active state of the signal source of aerocraft correctly and the reliably by analyzing or comparing the read-back data and signal source. What's more, it has been proved the read-back data of spare port is same as the data of long range line after analyzing the data of spare port. Therefore, the memory can gain the true data after aerocraft firing and the firing process can be played back.
