| 摘 要： | 介绍一种对图书馆噪音进行监测的无线收发系统,主要对图书馆自习室内的噪音进行实时的监测,噪音过高且持续时间较长则通过无线发射报警信号给图书馆管理员的接收器,管理员通过接收器了解噪声源的位置并采取相应管理措施。本系统以ARM7为系统核心,主要使用PT2262,PT2272,MICRF102,MICRF107等芯片组成无线收发模块,用声音传感器,5G14433A/D转换芯片,计时芯片74LS163等组成声音采集判定模块,对声级进行阀值判定。

| Abstract: | It introduce a kind of system for monitoring the noise sound of the library. It can supervise the studying room at real rime. If the pitch of the room is higher enough and lasts a certain time, the alarm signal will be sent to the receiver in he librarian,then librarian takes some measure to handle this. The system set the ARM7 as the core,using PT2262, PT2272, MICRF102, MICRF107 chip as the main components of wireless transceiver modules,with the voice of sensors, 5G14433A / D conversion chip,time chip 74L... |
