超小型包覆成型干簧管传感器59170在无线门磁报警器中的应用

技术问答

力特（LITTELFUSE）的59170干簧管是一款超小型包覆成型干簧管传感器，干簧管传感器的尺寸为11.43mm x 2.29mm x2.29mm，为常开触点，因其体积小巧、结构稳定、簧片触点的工作周期可达数百万次，而常用于安保、门窗报警系统。

无线门磁报警器是智能家居安防防盗报警领域的常见产品，是一款用于家庭门窗的防盗设施，主要包括无线发射模块、微控制器、电源及干簧管，产品一般由电池供电。干簧管的应用方式为：一端与微控制器IO引脚连接，另一端接地或者接电源，一般无线门磁产品还都具有防拆按键用于防止产品被异常拆卸。

图2 产品框图

无线门磁报警器的基本工作原理是通过磁铁（铁氧体永磁铁）与干簧管之间的距离来控制干簧管的开关状态，磁铁和门磁装置分别装在门和门框上，若磁铁与干簧管距离较远时，干簧管处于断开状态，当磁铁与门磁距离小于一定值时，干簧管变成闭合状态，造成短路，微控制器获取干簧管的不同信号，向无线发射模块发送不同信号，无线发射模块进而向主机发送信号，主机根据不同信号发出不同的报警音或讯号。

59170干簧管应用于无线门磁的设计简单实用，本项目中设计的磁铁磁力配合59170干簧管在两者距离大于2cm的状态下干簧管弹片断开，小于2cm的状态下弹片吸和，这有利于安装的时候考虑门窗之间的缝隙存在，同时也保证了产品的感应灵敏度。我们还制作了治具测试干簧管的可靠性，在磁铁作用下，将干簧管进行1万次的开合动作，测试结果为可靠性高达100%。

力特的59170干簧管相比其他玻璃管封装的干簧管传感器不容易破碎，门磁产品因为安装在门框上所以需要保证干簧管是安全可靠的。在PCB设计上，常采用挖槽方式处理，59170干簧管具有翼形引脚封装，可以很好的放置在pcb上，PCB采用挖槽设计既可以在结构上减小产品厚度节省空间，还可以更好的保证干簧传感器不受伤害，如图3所示。本无线门磁因电池供电，所以需要做到低功耗的特点，采用MCU自带上拉电阻配合59170检测其开合状态。
