基于嵌入式实时操作系统的智能矿灯设计

摘要

In view of problems of being unable to sense underground environment parameters and failing to form two-way real-time communication network between underground and ground caused by single function of miner lamp,an intelligent miner lamp based on embedded real-time operating system was designed.The lamp takes STM32 chip as main control center,and collects environmental temperature,gas concentration and personnel movement status by using temperature sensor,gas sensor and acceleration sensor respectively.The NRF24L01 wireless communication module reads status of underground positioning and material label to obtain personnel position and material information;data is uploaded to the ground server via WiFi for display and storage.The lamp has both manual alarm and automatic alarm functions,the host computer can send information to achieve two-way communication between underground and ground.Test results show that the intelligent miner lamp is stable and reliable,easy to operate,and has high real-time performance.%针对目前煤矿矿灯功能单一,无法感知井下环境参数,未能和地面构成双向实时通信网络的问题,设计了基于嵌入式实时操作系统的智能矿灯.该智能矿灯以STM32芯片为主控核心,利用温度传感器、瓦斯传感器和加速度传感器分别采集环境温度、瓦斯浓度及人员运动状态;通过NRF24L01无线通信模块读取井下定位与物资标签状态,获取人员位置与物资信息;通过WiFi将数据上传到地面服务器进行显示和存储.该智能矿灯还具有手动报警与自动报警功能,上位机可下发信息,实现井下与地面的双向通信.测试结果表明,该智能矿灯性能稳定可靠,实时性高,操作方便.
