摘要
针对现有的被动红外传感防盗报警系统存在的不足,提出了一种改进的系统。采用双元红外传感器及多种抗干扰软硬件设计,改进了已有被动红外防盗报警系统误报率较高的缺陷;基于GSM无线网络并适配市面上的主流手机卡,实现了现场与手机短信方式的同时报警,以便利的方式改进了绝大多数现有系统不能告知场外用户的不足;采取多种措施,在节能方面作了改进。实测结果表明:改进后的防盗报警系统误报率不高,能实现入侵现场与手机短信的同时报警,较好地解决了现有系统存在的缺陷,且方便实用,节能环保,具有广阔的市场应用前景及拓展应用价值。
Concerning on the disadvantage of the passive infrared detector, this paper puts forward an improved infrared detector system. The system takes the advantage of double infrared sensor and anti-interference design, so it can efficiently solve the problems about high misinformation rate. Moreover, it is likely to send messages to users who are absent, because the system is based on GSM network. The test indicates that this system lowers the rate of misinformation, alarms inside and outside at the same time. In terms of practical application, it is more convenient and has low costing. Thus it may be expanded in the future market.
