基于STM32的分体式通用报警器的设计

Design of the Split Type Alarm Apparatus Based on STM32

报警器大多采用一体化结构,且往往只针对某一类型报警信号专属专用,缺乏通用性,因此基于STM32单片机设计了一款具有主、副板结构的分体式通用报警器。主板由电源电路、传感器、短信发送模块和继电器模块组成,副板带有传感器和电池电路等。主、副板之间通过PT2262/PT2272编解码芯片进行无线通信。试验证明分体式结构灵活可靠,实用性强;报警器输出接口多样,便于用户扩展,具有较强的通用性。

Most of the alarm apparatus have the integrated structure,which has relatively narrow application. Therefore,a kind of general split type alarm apparatus with the main and slave board was designed based on the STM32 MCU. The main board which contained the power supply circuit,sensors,SMS module,relay modules and so on. The slave board was designed with sensor and battery circuit and etc. The PT2262/PT2272 was used for wireless communications between the main board and the slave board. Experimental results show that the split type design of alarm apparatus is flexible and reliable. The multiple output interfaces are easy for users to expand,therefore the alarm apparatus has good generality.
