用于红外探头故障自检的无线联网智能报警器设计

Design of Wireless Networked Intelligent Alarm System for Fault Detection of Infrared Probe

针对传用于红外探头故障自检的报警器一直存在漏报、误报的问题,设计了一种无线联网智能报警器,以无线路由器、传感器及单片机组成无联网线智能报警器,将报警信息通过局域网TCP/IP传输到上位机。报警器由热释电红外线探测电路和无线联网感应模块实现其工作原理,在现有的局域网上实现安防网络的布控,减少铺设线路的费用。该报警器通过无线网络传输协议、无线网络数据传输、无线网络监控软件实现无线网络的传输与监控,智能检测各探测器是否正常工作,并实时保存报警信息以便回放,对报警信息的类别及具体警报地点进行图形显示。经过实际应用测试,漏报、误报现象较低,有效提高报警器的安全、稳定性能,能够很好的提高红外探头故障的自动检测。

According to the transmission alarm for infrared sensor fault detection has been missing andfalse problem,designed a kind of wireless network with intelligent alarm,wireless router,sensor and MCUwithout contact cable intelligent alarm,alarm information is transmitted to the host computer through theLAN TCP/IP.The alarm system is composed of pyroelectric infrared detection circuit and wirelessnetwork induction module and its working principle,implementation of network security surveillance inthe existing LAN,reduce the cost of laying lines.The alarm transmission and monitoring wireless networkthrough the wireless network transmission protocol,wireless network data transmission format,wirelessnetwork monitoring software,intelligent detection of the detector is working properly,and save real-timealarm information to playback of alarm information and the alarm location for specific categories ofgraphic display.Through the practical application test,the missing and false phenomenon is relatively low,effectively improve the safety and stable performance can improve the automatic detection alarm,infraredsensor fault is very good.
