设计并实现了基于微震信号检测的煤矿求救信号监测系统,该系统由信号发生装置和信号接收装置2部分组成。信号发生装置将需要发送的信息进行波形编码,通过单片机控制电磁阀,以气动敲击器作为执行单元,从而将数据信息转变为振动波形;信号接收装置使用微震传感器接收到微震信号,进行滤波放大之后,通过编译码规则将振动波形转换成原始数据信息,并在LCD上进行显示,同时声光提示。试验证明,该装置能够有效接收到金属管道上传递的震动信号。
Design and implementation of mine rescue signal monitoring system based on microseismic signal detection. The system consists of two parts: signal generator and signal receiver. The signal generating device will need to send the information waveform encoding, controlled by the single-chip solenoid valve to the pneumatic percussion device as the execution unit, which will transform the data into a vibration waveform; signal receiving device using microseismic sensor to receive the microseismic signal, the filter amplification After that, the vibration waveform is converted into the original data information by the codec rule, and displayed on the LCD, meanwhile, the sound and light prompts. The test proves that the device can effectively receive the vibration signal transmitted on the metal pipe.
