摘要
瞬变电磁发射机是瞬变电磁系统的组成部分。论文介绍了瞬变电磁发射机控制系统的功能框图、硬件设计和软件设计,实现了发射电流、关断延迟时间的测量,以及内同步外同步双工作模式,发射机具有发射电流大、关断延迟时间短、下降沿线性度高的特点。实验证明,该控制系统功能完善,可靠性高,达到了设计要求。
Transient electromagnetic transmitter is a part of transient electromagnetic system. The paper introduces the functions to be needed for the control system of transient electromagnetic transmitter, the design for the hardware and the software. The control system can measure the transmitted current and switch-off time, and make the transient electromagnetic transmitter run in two different modes. The transient electromagnetic transmitter has three features： the large transmitted current, the short switchoff time and the current decline in line ramp. The control system proved by experiments has perfect functions and high reliability, and it attains the design demand.
