【摘要】 在煤矿应急救援过程中,能否快速获知遇险人员所处方位对于整个救援行动的影响相当大。目前,常用的生命探测仪具有操作复杂、价格昂贵等弊端,为此设计并实现了一款使用简单、性价比较高的主动式生命探测仪。该仪器发送端能在人员持续无动作或主动按键求救的情况下采集人员体温信息,并发送给地面接收端,其接收到信息时对此进行LCD显示。针对发送端被掩埋的情况设计并完成了信息传输实验,实验表明,该主动式生命探测仪能在被砖石和沙土掩埋2.5 m深的情况下顺利发送和接收数据信息。更多还原

【Abstract】 In the process of emergency rescue in coal mines,to rapidly acquire the location of rescuees plays a significant role in mine rescue.There are kinds of life detectors in common use,but they are always difficult to be manipulated and vary expensive,which restrict their popularization in China.For this purpose,an inexpensive active life detector that is easy to operate and has high performance-price ratio was designed and implemented.This life detector is comprised of two parts: the transmitter and the receiver.The transmitter can acquire SOS and rescuee’s heat information and transmit them to the receiver when the user stops moving or when the user pushes the SOS button.The information is displayed on LCD of the receiver.Information transmission experiments were conducted according to the conditions that the transmitter may be buried and the result showed that information can be transmitted and received successfully when the active life detector was buried 2.5m deep underground.更多还原
