Abstract：Due to the differences of impact testing machines' structure，power source and application field，their measure & control systems are also different. Aiming at the limitation of traditional measure & control system can only be applicable to certain specific type of impact testing machine，a new method of measure & control system based on Nios-II processor was proposed. According to the different peripheral interfaces of the machines，the presented system is suitable for various types of machine through dynamically configuring process and selecting appropriate peripherals. Finally，the data acquisition of time-domain waveforms and tolerance analysis were carried out in field experiment. Test results show that the system fits for the testing and measuring in different types of impact testing machine，and is worthy being widely applied.
