Research on Computer Measure and Control System of Electromagnetic Rail Gun

In order to monitor the transient state and get more data of the electromagnetic launch system in the research of the electromagnetic rail gun, many signals need to be controlled and acquired, so the computer measure and control system is an essential part of the entity. Firstly, this paper introduces the structure of the system which is controlled and measured by using serial and optical fiber communicate and data acquisition card. Secondly, it presented the block diagram of the control system and the design method of hardware circuit interface. Then, it introduces the key technology referring to multithread, data acquisition and data storage in the software. Proved by experiment, this measure and control system is steady. It realizes the isolation between signal portion and computer portion, and assured the security of equipment under super current. The launch time can be controlled by software time delay. The software has character of Modularization, integration and Windows interface. It not only can control all the experiment directly, but also can control, acquire and analyze data from much more access by expand modules.
