文中设计了一种针对某型自动驾驶仪系统全套性能进行测试与检查调整的测试系统。整个系统采用分布式控制系统,上位机实现对采集数据的处理、保存和故障诊断等多方面的功能,同时对下位机的运行情况进行监控;下位机采用TMS320LF28335,实现采集被测信号并发送需要测试设备输出的信号,同时将采集信号与输入信号进行比对;上位机与下位机通过RS485串口通信总线进行数据交换。经测试,该系统实现了对某型自动驾驶仪全套性能的检测,并且性能优越,提高了该驾驶仪的技术保障水平和工作效率、缩短了维护保障时间。
In this paper, we designed a test system for testing and checking the full performance of a certain type of autopilot system. The entire system uses distributed control system, the host computer to achieve the collection of data processing, preservation and fault diagnosis and other functions, while the lower computer operating conditions to monitor; lower computer using TMS320LF28335 to achieve the collection of the measured signal and send the need Test equipment output signal, at the same time the acquisition signal and the input signal to be compared; PC and lower computer through the RS485 serial communication bus for data exchange. After testing, the system has realized the full performance test of a certain type of autopilot and has superior performance, which improves the technical support level and working efficiency of the autopilot and shortens the maintenance and safeguarding time.
