摘要中国作为一个比较依赖煤炭能源的国家，工厂生产、工业技术制造急需煤炭资源的利用。但是煤矿井下环境恶劣，煤粉尘多，对于煤炭资源的开采与挖掘并不是十分地有利。稍有不慎，电气火花就会产生，进而导致瓦斯等易燃气体的爆炸。因此，对于煤矿井下的安全作业，我们需要特别注意。而说到煤矿井的安全问题，就不得不提生产作业使用的煤电钻。过去，手持式的煤电钻综保开关的开关器件大多使用的是交流接触器，触点闭合时易产生火花。而且手持式煤电钻的开关体积大、重量大，保护功能不健全，可靠性和安全性差。因此，随着时代的发展，煤矿井下煤电钻综保开关设备不得不在功能保护和性能优化上作出进一步的要求。69184
本设计研究的智能型煤电钻开关是以固态继电器作为开关器件，以AT89C51单片机为核心，通过CPU主系统判断电路有无故障发生，有故障则断开固态继电器开关，无故障则发出脉冲信号，使煤电钻电源导通。另，本文的核心创新点在于使用51单片机系统控制煤电钻电源的通断以及设计了直观可视的人机智能保护界面，便于操作工检查设备故障，减少设备的维修工作量。

Of non-contact electric switch for mine design and research
Abstract
As a country that relies more on coal energy in China, factories, industrial use of technology to create much-needed coal resources. But the underground mine environment, coal dust, coal mining and mining is not very favourable. The slightest mistake, electric spark occurs, leading to explosion of flammable gases such as methane. Therefore, the coal mine security job, we need to pay special attention. And when it comes to coal mine safety issues, we must mention the production of coal electric drill. The past, handheld electric coal drill comprehensive conservation switch most of the switching device is on AC contactor, easy to produce sparks when the contact is closed. Handheld electric coal drill switch of large size, weight, protection is not perfect, poor reliability and safety. Therefore, with the development of coal mine coal-drill integrated protection switch devices have to function under protection and performance optimization to make further demands. Research on the design of an intelligent coal electric drill switch is based on solid state relays as the switching device, with AT89C51 microcontroller core, judging circuit through the CPU system has no fault, faulty disconnect solid state relay switch, trouble-free pulse signal is issued, coal electric drill power conducting. Another core innovation of this paper is to use 51 single-chip computer control system of electric coal drill power switching and the design of intelligent protection of intuitive, Visual interface, easy to check the equipment failure, reduced equipment maintenance workload. The paper has 25, table 4, 13 references are presented.
Key words: 51 single chip solid state relay intelligent protection switching
