摘要
在煤矿井下实际生产中,放炮员可能不洒水就开始放炮,容易发生放炮爆炸事故。针对该问题,文章提出了一种由P89LPC932单片机控制的基于倍压整流电路的煤矿放炮前自动洒水控制系统的设计方案,详细介绍了系统组成、功能、工作原理及主要电路的设计。样机系统的应用表明,该系统不但满足了不洒水不能放炮的要求,而且可以根据现场设定的洒水总量实现洒水闭锁功能,实用性好。
In actual production of coal mine underground, the shot lighter may begin to shoot but no sprinkling water which is liable to shoot explosion accident. For the problem, the paper proposed a design scheme of automatic sprinkling water control system before shooting of coal mine based on voltage doubling rectifier circuit controlled by P89LPC932 single-chip microcomputer, and introduced configuration, function, working principle and design of main circuits of the system in details. The actual application of prototype system showed that the system not only meets the demand of no shooting no sprinkling, hut also realizes sprinkling locking function according to the total sprinkling set in field, which has strong applicability.
