Abstract: For better accuracy and real-time performance, one development scheme based on ARM7 and μC/OS-Ⅱfor the control system of universal material testing machines has been proposed. Taking the flexibility of the testing machine control system into consideration, the hardware was designed in different modules so that it could be used in different testing machine. In the side of software, the tasks were divided according to the principle of embedded OS and the hardware resource of the system, so that the control system could run faster and cost less in resource. It has been verified that the embedded control system of universal material testing machines is with excellent data collecting accuracy, excellent real-time performance, excellent flexibility, and so on.
