A hardware environment of an embedded towed target comprehensive test equipment is builded,which based on PC104 board and the towed target test interface signal analysis. VC++ software programming is adopted in Windows XP operat?ing system to achieve the towed target parameters of the interactive test,through making full use of hardware sources such as mainboard serial interface and digital input/output interface,supplemented with signal level conversion and coding circuit. The principle diagrams of the signal level conversion and the coding,and the hardware connection diagram as well are presented. The timer interrupt is employed to complete the query and read of input pin on DIO interface. It makes the software interface dis?play more vivid through the application of CUniButton class. The application results show that the system design works reliable, the interface is succinct and the operation is simple.
