I. INTRODUCTION With the development of computer technology and electrical measurement technology, the programmable data acquisition system based on single chip microcomputer has developed rapidly. It has played an important role in the control of the production process and scientific research. In the production process, the system can be used to test, monitor, record and control the production site to provide information and means to improve product quality and reduce production costs. In scientific research, using this system to obtain a large amount of dynamic information is a powerful tool for studying transient physical processes, such as in the fields of aerospace, aviation and production technology, and in the fields of explosion, combustion and machinery, etc. Has become one of the important means to obtain the mysteries of science.
