摘　　要：为震电勘探而设计的一种控制放炮设备———震电法自动定时放炮系统 ,是用笔记本电脑作为控制中心 ,具有安全轻便、交互性强及起爆时间短等特点。震电法自动定时放炮系统研制成功使非地震勘探中引入炸药震源激发电磁信号成为可能。文章阐述了系统设计思想和软件功能 ,介绍了系统中光电耦合隔离、译码逻辑、驱动控制等电路特点。Auto-time shooting system is a shooting control equipment to design for electroseismic prospecting. A notebook computer is used as the control center,which makes the system easy to carry,safe to operate,high interactivity and short detonating delay. The paper mainly introduces the circuit functions and an idea of hardware design,including of optic-coupling isolation,decoding logic and drive control and so on,as well as software functions. It will satisfy the requirements of detonating control in electroseismic prospecting to successfully develop such the system,and which will makes it possible for dynamite source activation to be introduced into non-seismic prospecting.
