Description

离子感烟传感模块
技术领域
本实用新型涉及火灾探测报警领域，特别涉及的是一种离子感烟传感模块。
背景技术
传统的火灾报警模式均是火灾发生后才报警，无法达到火灾监控预警的目的。
实用新型内容
本实用新型的目的在于克服上述不足，提供一种达到火灾监控预警目的的离子感烟传感模块。
本实用新型解决其技术问题所采用的技术方案是：离子感烟传感模块，包括离子感烟传感器电路、语音芯片电路和功率放大报警电路，所述离子感烟传感器电路的输出信号经开关电路传输到语音芯片电路，所述语音芯片电路的输出信号发送到功率放大报警电路。
所述离子感烟传感器电路采用内电离室与外电离室的离子感烟传感器AM2、AM1采集信号。
所述语音芯片电路采用9561A语音芯片IC2。
所述功率放大报警电路由LM386音频功率放大器IC1及其输出端连接的扬声器Y构成。
通过采用上述的技术方案，本实用新型的有益效果是：当烟雾等燃烧生成物进入检测电离室时，本实用新型经离子感烟传感器采集信号，经开关电路触发，发出语音报警，达到火灾监控预警。
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
下面结合附图对本实用新型作进一步的详细说明。
如图1、图2所示，本实用新型的离子感烟传感模块，包括离子感烟传感器电路1、语音芯片电路2和功率放大报警电路3，所述离子感烟传感器电路1的输出信号经开关电路11传输到语音芯片电路2，所述语音芯片电路2的输出信号发送到功率放大报警电路3。
所述离子感烟传感器电路1采用内电离室与外电离室的离子感烟传感器AM2、AM1采集信号，内电离室作补偿用，外电离室作检测用。当烟雾等燃烧生成物进入检测电离室时，离子感烟传感器AM2、AM1的公共输出端电位升高，并促进三极管VT2导通，当烟雾浓度达到一定程度，三极管VT2的输出电压达到某一值时，使9561A语音芯片IC2得到工作电压，9561A语音芯片IC2输出音频信号，经电容C3耦合到LM386音频功率放大器IC1的第3脚，经LM386音频功率放大器IC1内部功率放大后，由LM386音频功率放大器IC1的第5脚输出，经电容C4耦合放大，扬声器YY发出语音报警，达到火灾监控预警。
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。
