摘　　要：针对现有矿用报警器存在的不足和弊端,设计出一种新型矿用报警器.设计采用本安电源供电,利用单片机控制技术,通过按键实现不同的语音播放和麦克风进行半双工通信,应用发光二极管和数码管显示警示信息和打点次数,利用RS485通信技术实现了远程控制.适用于煤矿井下具有瓦斯、煤尘爆炸危险的各个轨道偏口、斜巷、弯道等场所,作为语音报警、安全警示和信息提示,具有保障安全生产的价值.Aiming at the shortcomings and drawbacks of the existing mine alarms,a new type of mine alarm is designed.Intrinsically safe power supply is adopted in this design,single-chip control technology is used,different voice playback and microphone for half-duplex communication is realized through buttons,light-emitting diodes and digital tubes is used to display warning information and the number of dots,and RS485 communication technology is applied to achieve remote control.The design is suitable for various tracks,inclined lanes,bends and other places where there is a danger of gas and coal dust explosions in coal mines.As a voice alarm,safety warning and information prompt system,it has the value of ensuring safe production.
