Abstract: For Windows system shortage of real-time monitoring and traditional control software are not universal, applicate RTX technology to enhance real-time Windows, use flexible scripting language to describe the test tasks, enhanced real-time monitoring and control software commonality; design and implement real-time monitoring and control software system based on RTX; describe the software design and implementation of key technologies, such as device identification, script specification design, I/O-driven development. The results show that on the one hand, RTX technology application solves the problem of lack of real-time Windows system, on the other hand, the design of the software system is able to complete different testing tasks by editing and performing different test scripts, and has great significance to solve the problem that Real-time monitoring and control software versatility is not strong.
