Description

一种安防短信报警模块
技术领域
    本实用新型涉及电子电路领域，特别涉及的是一种安防短信报警模块。
背景技术
传统的安防报警电路大部份采用有线或无线方式报警，具有报警距离短或组网报警不方便、成本高、性能不稳定等缺点。
实用新型内容
本实用新型的目的在于克服上述不足，提供一种安防短信报警模块。
本实用新型解决其技术问题所采用的技术方案是：一种安防短信报警模块，包括有红外信号采集电路、单片机控制电路和GSM模块电路，所述红外信号采集电路的输出信号经放大器电路传输到比较器电路，所述比较器电路的输出信号经单片机控制电路发送至GSM模块电路。
所述红外信号采集电路采用红外传感器BH采集人体信号。
所述单片机控制电路采用2051单片机IC1。
通过采用上述的技术方案，本实用新型的有益效果是：当红外信号采集电路采集到人体信号时，本实用新型经信号放大、比较处理后，由单片机控制电路判断，驱动GSM模块电路向指定人员的手机号码发送报警信息，是组网简单、性能可靠的新一代无线传输报警装置。
附图说明
图1是本实用新型的方框结构图；
图2是本实用新型的电路原理图。
具体实施方式
以下结合附图和具体实施例来进一步说明本实用新型。
如图1所示，本实用新型的一种安防短信报警模块，包括有红外信号采集电路、单片机控制电路和GSM模块电路，所述红外信号采集电路的输出信号经放大器电路传输到比较器电路，所述比较器电路的输出信号经单片机控制电路发送至GSM模块电路。
如图2所示，所述红外信号采集电路采用红外传感器BH采集人体信号，红外传感器BH能在较远的距离探测到人体移动所发出的微弱红外线，当红外传感器BH检测的人体移动所发出的红外线信号时，经转换成为低频电信号，由红外传感器BH的第2脚输出到第一运算放大器IC2/A进行放大，然后由第一运算放大器IC2/A的输出端经电容C7耦合至第二运算放大器IC2/B对信号作进一步放大。
第三运算放大器IC2/C和第四运算放大器IC2/D构成电压比较器，当第三运算放大器IC2/C和第四运算放大器IC2/D输出高电平，其分别经二极管VD6、VD7相互隔离（正或门）的作用，再经电阻R12输出高电平信号，输入到2051单片机IC1的第18脚I/O端，也呈高电平状态，经2051单片机IC1内部处理并判断为有非法人员入侵，发出控制信号，由2051单片机IC1的第11脚输出端连接的GSM模块IC3，由2051单片机IC1向IC3发出驱动信号，经GSM模块IC3内部电路译码后，经基站网络传输，向指定人员的手机号码发送报警信息，及时通知保安人员到达现场，具有可移动安装、联网报警方便、通信报警距离远等优点。
以上所述的仅为本实用新型的一较佳实施例而已，不能限定本实用新型实施的范围，凡是依本实用新型申请专利范围所作的均等变化与装饰，皆应仍属于本实用新型涵盖的范围内。
