For the conversional earthquake precursor data acquisition, its specificity and bad commonality leads to the difficulty for us to observe and maintenance instrument. 

It this paper, the multi-channels and general data acquisition was developed, which has six channels with 24 bit high-accuracy AD. In addition, it has many good features such as easily setting the sampling frequency by user program, adjusting the input signal voltage range by hardware setting and remote transferring data and monitoring instrument by internet, especially its capacity to connect most of the seismic precursor

 sensors.
