背景技术Background technique
在城市的各住宅小区中，为了防止主人不在家时盗贼从阳台入室盗窃，不少家庭在阳台上安装了防盗网，然而由于栏栅式钢结构防盗网设置在阳台上会造成阳台整体效果不美观，很多小区禁止在面向中心花园侧的阳台上安装防盗网。开放式阳台如果没了防盗网的防护，防盗问题始终让人难以放心，于是很多家庭在开放式阳台上安装防盗报警器。市面上的防盗报警器种类繁多，但通常只能起到发现盗贼入侵进而报警作用，不能在盗贼接近时就主动示警，当此类防盗报警器报警时，盗贼往往已进入，这时盗贼反而会选择孤注一掷，继续迅速行窃后离开，因此我们希望开发一种基于人体红外感应模块的防盗报警器，此类报警器能够在盗贼接近阳台时就监测到并自动进行声光示警，使其不敢轻易地做出行窃决定，从而保护家庭财产的安全。In various residential quarters in the city, in order to prevent thieves from burgling from the balcony when the owner is not at home, many families have installed anti-theft nets on the balcony. Beautiful, many residential areas prohibit the installation of anti-theft nets on balconies facing the central garden side. If the open balcony does not have the protection of the anti-theft net, the anti-theft problem is always difficult to worry about, so many families install anti-theft alarms on the open balcony. There are many types of anti-theft alarms on the market, but usually they can only detect the intrusion of thieves and then call the police. They cannot actively warn when the thieves approach. Choose desperate, continue to steal quickly and then leave, so we hope to develop an anti-theft alarm based on the human body infrared sensor module, this type of alarm can detect when the thief approaches the balcony and automatically give a sound and light warning, so that it does not dare to easily Make stealing decisions more accurately, thereby protecting the safety of family property.
