【摘要】 热功率模拟系统用于测试整星热平衡试验时模拟星上各设备热量分布情况,以检测整星的热控系统性能。本系统采用数字信号处理(DSP)组成单元处理系统,采用控制器局部网(CAN)总线组成通信网络,通过计算机对每一路功率按照预先设定好的功率曲线进行调控、巡检、记录。更多还原

【Abstract】 The heat power simulation system is used for simulating the amount of heat in satellite-equipment in heat balance experiments,to check the performance of the whole satellite under heat control.In this system,the main part of the control unit is DSP microprocessor,and the communication is conducted with CAN bus.Adjustment,cycle-check and recording of the power of each way are controlled by computer,and each power-out can be automatically adjusted depending on the preset curve.更多还原
