基于双模接口的测试系统设计

The Design of Test System Based on Dual Mode Interfaces

摘要:

为了对飞行设备进行各种性能参数的测试,同时避免因环境因素而带来的数据传输不稳定的问题,使用双模接口(以太网接口与USB接口)实现上位机与测试系统的通信,通过对采样电路进行优化产生多路高精度信号并实时监测接收返回的群信号。经实验证明,系统完全可以完成各种环境中的功能测试,并提高了系统测试精度与传输数据的可靠性。

Abstract:

According to test for a variety of performance parameter of flight equipment, while avoiding instability problems of data transmission caused by environmental factors, Using dual-mode interfaces (Ethernet interface and USB interface) to communicate with the PC and testing system .By optimizing the sampling circuit generates signals and multi-channel high-precision signals and real-time monitor receives the returned group signals .The experimental evaluation shows that the system can complete a variety of functional testing environment and improve the testing accuracy and the reliability of data transmission system.
