基于AT89S52单片机的井下水幕自动防尘控制系统设计

Design of Underground Water Curtain Automatic Dust Control System Based on AT89S52 Single-chip Microcomputer

针对目前煤矿运煤输送带处水幕自动防尘控制系统存在的缺点进行了研究和分析,设计了一种基于单片机的井下水幕自动防尘控制系统。该系统主要采用AT89S52单片机为控制核心,实现了对出水电磁阀门的自动控制,在运煤输送带运行过程中即可降水进行防尘,并且可以在输送带停止运行后延时3 min降尘,再由粉尘传感器检测现场粉尘浓度,达到国家标准时再关闭电动阀门。在所运行的运煤输送带人行侧,通过连接手动截止阀、单向阀以及三通,对水幕进行控制,以达到扩大防尘降尘范围的目的,加强了工作面和输送带巷的防尘降尘效果。

In view of the present the coal belt automatic control water curtain dust the shortcomings of the system is studied and analyzed, designed a kind of underground water curtain automatic dust control system based on single chip microcomputer. The system uses AT89S52 microcontroller as the control core, realizes the automatic control to the water outlet electromagnetic valve, in the coal belt in the running process of precipitation of dust can be, and can in belt stop running after a 3 minute delay dust, the dust sensor detection field dust concentration, and then close the valve to reach the national standard. In operation of the coal belt line side, connected by a manual cut-off valve, check valve and the three pass, control the water curtain, to expand the range of dust proof, strengthened the work surface and the effect of dust belt.
