摘要：煤炭是我国的主要能源，由于受到复杂地形条件的限制，各地经常发生生产 事故，造成人员死伤，经济损失惨重，因此国家和各地高度重视安全生产问题。 为满足煤矿安全生产的需要。 。近年来，我国煤炭业安全形势日渐严峻，重大安全事故频发，损失惨重。为 尽量避免此类安全事故的发生，降低不必要的损失，迫切需要建立一个高效的实时数据采集监控系统来进行安全预警。目前我国有很多先进的数据采集监控系统 已经投入使用，但是它们大多数是采用有线布局，灵活性差，技术的综合运用相 对较少，满足不了煤矿生产安全监控的要求。基于以上原因，技术革新势在必行。 针对目前矿井安全数据采集监控系统的不足，本文设计了一种基于物联网技 术的新型数据采集监控系统。系统通过物联网技术，4G无线收发模块与温湿度传感器、瓦斯传感器、CO传感器、CO2传感器、粉尘浓度传感器、光照强度检测传感器结合成系统的数据采集节点，负责对矿井内部的环境参数进行采集。将检测的数据通过4G模块实时传输到管理人员的手机端，且管理人员可以远程对这些设备的参数进行设置。监测到甲烷、温度、湿度、CO、CO2大于设置的最大值控制通风继电器打开，监测到粉尘大于设置的最大值控制加湿器进行工作降尘，检测到光照强度小于设置的最小值控制照明灯打开，监测到甲烷、温度、湿度、CO、CO2、粉尘大于设置的最大值声光报警；此外，无线网络的性能指标提升很大。测试结果表明，系统总体性能良好，稳定可靠，达到 了设计要求。

Intelligent Monitoring System for Mine Environment Based on Internet of Things
Abstract: Coal is the main energy source in China. Due to the limitations of complex terrain conditions, production accidents often occur in various regions, resulting in casualties and heavy economic losses. Therefore, the country and various regions attach great importance to safety production issues. To meet the needs of coal mine safety production. In recent years, the safety situation in China’s coal industry has become increasingly severe, with frequent major safety accidents and heavy losses. To minimize the occurrence of such safety accidents and reduce unnecessary losses, it is urgent to establish an efficient real-time data collection and monitoring system for safety warning. At present, many advanced data collection and monitoring systems in China have been put into use, but most of them adopt wired layout, with poor flexibility and relatively limited comprehensive application of technology, which cannot meet the requirements of coal mine production safety monitoring. Based on the above reasons, technological innovation is imperative. In response to the shortcomings of the current mine safety data collection and monitoring system, this article designs a new type of data collection and monitoring system based on Internet of Things technology. The system combines 4G wireless transceiver modules with temperature and humidity sensors, gas sensors, CO sensors, CO2 sensors, dust concentration sensors, and light intensity detection sensors through Internet of Things technology to form a data acquisition node, responsible for collecting environmental parameters inside the mine. The detected data will be transmitted in real-time to the management personnel’s mobile phone through the 4G module, and the management personnel can remotely set the parameters of these devices. If methane, temperature, humidity, CO, and CO2 are detected to be greater than the set maximum value, control the ventilation relay to open. If dust is detected to be greater than the set maximum value, control the humidifier to reduce dust. If the light intensity is detected to be less than the set minimum value, control the lighting to turn on. If methane, temperature, humidity, CO, CO2, and dust are detected to be greater than the set maximum value, sound and light alarms will be triggered; In addition, the performance indicators of wireless networks have greatly improved. The test results show that the overall performance of the system is good, stable and reliable, and meets the design requirements.
