执勤枪支全无线综合定位报警技术研究

Wireless Location and Alarming Technology for Firearms

系统采用多种无线定位方式和低功耗嵌入式设计,综合运用低频载波定位、宽带线性调频扩频定位、通信基站定位、无线通信技术,可实时显示哨兵活动轨迹,具备无线定位、离位报警、断线报警、失电报警和防拆卸功能。系统采用全无线的方式,在确保定位精度的同时降低了系统功耗,实现了岗哨、应急值班室、监控中心的警情联动。

The system can display the movement traiectory in real time with wireless location, off station alarming,open-circuit alarming, power-loss alarming and anti-disassembly functions,which using a variety of wireless positioning mode and low power consumption design. The system comprehensive uses the low frequency carrier wave positioning,the broadband linear FM spread spectrum,the commu nication base station positioning and the wireless communication technology. The system adopts entirely wireless method, that ensures the location precision with low system power consumption and achieves the alarm linkage of the sentry, the emergency staff on duty and monitoring center.
