OBJECTIVE To develop an ergometer signal acquisition and analysis software to study ergonomics of work load in a spacecraft artificial control system. Method It is an important part of the whole set of experimental device, which is realized on the computer. It mainly consists of acquisition display program, analysis and processing program and data file. As a result, it can collect, display, and analyze offline and analyze and process the four-way EMG signals and one operation control signal in real time. Conclusion During software development, technical measures such as extension processing of visual display and signal acquisition tasks, frequency division processing of EMG signals and operation control signals, sampling periods, display periods and storage periods are set up to improve the software real-time. In addition, it also has the characteristics of high reliability, high data accuracy and human-friendly interface.
