摘要
在煤矿井下人员定位系统的基础上研制了基于Cortex_M3的手持便携式人员搜救器。当发生矿难时,搜救器通过自动搜索机制,由探测被困人员携带的2.4G定位卡,通过改变PA增益精确定位被困人员,并且确定其身份;通过2.8寸全彩OLED屏实时显示当前探测到的人数、方位、身份等信息;并通过红外传送给计算机。
The portable personnel searching and rescuing device is developed successfully by an ARM SCM whose core is Cortex_M3 with the underground personnel positioning system.When the mining accident occurs,this device can through the auto search mechanism survey the 2.4G locator card which on personnel body.The change of PA can increase the pinpointing precision of stranded personnel and determine their status;then through 2.8 inch entire color OLED screen to display the information in real-time of currently surveyed population,position,status and so on.The information collected is transmitted to the computer through the infrared communication.
