基于单片机编码寻址的矿山井下照明系统设计

Design on the lighting system of underground mine based on single-chip code addressing

矿山井下照明安全性要求高,通常避免现场操作而进行远程控制。介绍了将电力线载波技术与集成编译码技术结合,进行可远程控制的矿山井下照明系统设计过程,并使用AT89C55WD单片机对PT2262编码器进行地址模拟编码,与PT2272译码器交换数据。该系统的设计不仅能满足对井下照明的远程控制需求,而且能有效克服矿井现场的电磁干扰、保证数据的可靠传输,对矿业生产安全有一定现实意义。

The underground mine lighting requires high safety, so the site operation is usually replaced by remote control operation. Combined power line carrier technology with integrated codec technology; the design process of the underground mine remote-colltrolled lighting .system is introduced. The system adopts the micro AT89C55WD to address PT2262 encoder analog encoding and exchange data with PT2272 decoder. The design of the system shows that it can satisfy, the lighting of the underground demand for remote control, overcome the mine-site electromagnetic intetference effectively ensure reliable data transmission and provide certain practical significance for the safery of mining production.
