一种定深点火电路的设计

Design of a Depth Setting Ignition Circuit

摘要:

应用于水下攻防的海洋装备在水下试验时，需具备在到达一定深度时能够自动点火的功能。针对这类海洋装备的需求，设计了一种定深点火电路。它可根据入水的深度，安全、可靠地进行点火输出控制， 继而实现如产品回收等功能。该电路在本单位的项目中得到了有效的应用与充分验证。定深点火电路主要由电源模块、单片机系统、传感器电路以及点火控制驱动电路等模块组成。

Abstract:

The marine equipment used in underwater warfare needs to have the function of automatic ignition when reaching at a certain depth during underwater test. In order to meet the requirements of this kind of marine equipment，a depth setting ignition circuit is designed. It can control the ignition output safely and reliably according to the depth of water entering，and achieve the functions such as product recovery. The circuit has been effectively applied and fully validated in our project. The depth setting ignition circuit is mainly composed of power supply module，MCU system，sensor circuit and ignition drive control circuit，etc.
