Detonation control circuit of miniature safety actuator

The invention provides a detonation control circuit of a miniature safety actuator. The detonation control circuit of the miniature safety actuator comprises a driving circuit, an isolation circuit, an energy storage circuit, a switch and an electric detonator. The output end of the driving circuit is connected with the isolation circuit, and the input end of the driving circuit receives a digitalsignal; and the output end of the isolation circuit is connected with the switch. An electromagnetic relay and a solid state relay are replaced by a field-effect tube, the circuit opening-closing functions are finished, the device size is small, the current-carrying capacity is high, and the miniature design of the safety actuator is facilitated. 本发明提供的种小型化安全执行机构起爆控制电路，包括驱动电路、隔离电路、储能电路、开关和电雷管；所述驱动电路输出端与隔离电路连接，输入端接收数字信号；所述隔离电路输出端与开关连接。本发明利用场效应管来替代电磁继电器和固体继电器，完成电路开关功能，器件体积小，载流能力强，有利于安全执行机构的小型化设计。
