卫星铷钟自动控温系统仿真平台的设计与实现

卫星上的铷钟对环境温度要求非常苛刻,需要采用自动控温系统严格控制工作环境的温度,该系统上星前必须经过大量的试验和仿真,验证卫星上铷钟热控系统的软硬件功能和性能是否达到设计要求。基于CPCI(Compact Peripheral Component Interconnect)计算机的卫星铷钟自动控温系统仿真平台,是在不具备铷钟热控试验需要的真空、绝热条件下,模拟铷钟在卫星上工作时温度变化引起的参数变化,并检测卫星铷钟自动控温系统由于参数变化所引起的相应的控制量变化,从而验证系统的性能。

Design and Realization of Simulator for Satellite Ru Atomic Clock Temperature Auto Control System

Satellite rubidium atomic clock requires very stable environment temperature,which should be controlled by temperature autocontrol system.The system should be rigorously simulated and tested to assure its function and performance before being implemented on satellite.When the vacuum and adiabatic environment which the rubidium atomic clock tests require cannot be obtained,the simulator based on CPCI bus for satellite rubidium atomic clock could simulate the parameter variations of the clock due to temperature fluctuations,detect the corresponding variations of control variable of the temperature autocontrol system,and thus evaluate the performance of the system.
