摘要
该报警器具有误报率较低、安装和配置容易、成本低、能量消耗少、使用非常方便的特点。实现的原理是感应震动信号,将其转换成超低频信号,经电路放大、输出。检测器是利用震动传感器SW-18015P,一旦有震动便向主机发出信号。而主机功能是通过无线接受信号,再经单片机处理,然后数码管显示出信号发出的具体范围并同时控制喇叭发出警告声音。可以应用于家居防盗、仓库防盗等多种防盗场合,具有很强的实用价值和良好的市场前景。
The alarm has a low rate of false positives, easy installation and configuration, low cost, less energy consumption, use very convenient. Induction is the principle of vibration signals, convert them to ultra-low frequency signal, after amplification circuit, output. Detector is the use of vibration sensor SW-18015-p, once has the vibration signal to the host. The host function is through radio signals, then through single chip, then the digital tube display out the specific scope of the signal and at the same time issued a warning sound control horn. Can be applied to household anti-theft, warehouse and wait for a variety of security situation, has the very strong practical value and good market prospects.
