In order to meet the needs of data acquisition for remote monitoring of missile test equipment, a data acquisition device for remote monitoring of test equipment is designed based on embedded technology. Taking the embedded computer as the core, and as a front-end information collection and processing equipment of the whole remote real-time running monitoring management system of test equipment, it is distributed at the test site to obtain the test site related information and report to the monitoring center. It is the main source of information of the monitoring center. The experimental results show that the data acquisition device is simple in structure, powerful in function, stable in operation and easy to expand. It can perform the function of data acquisition for remote monitoring of missile test equipment.
