The Research Of Synchronous Data Acquisition Network System Of Rock Burst Micro Vibration

With the development of social economics, the energy demand in China will grow increasingly,. With increasing depth of all kinds of mining resources, disaster is more easily to be destroyed. Once a disaster occurs, it will be difficult to escape. Some tiny vibration will occur before rock collapse and bridge rupture in the mine. If you can find these tiny vibrations at the first time, then warning and other related measures can be take immediately,damage would be reduced caused by natural disasters. So it plays a key role in the safety to establish a set of microseismic monitoring system in the mine.Micro-seismic monitoring system at home and abroad is studied. Wavelet analysis of microseismic signal and the principle of hypocentral location have been analyzed. A set of hardware system with two ARM chips and one FPGA chip has been designed. One ARM is used for time synchronization operation periodically, another is used for receiving data. and network communication. This system supports 12 channel data acquisition, acquisition network can be composed of several kind of system. The clock synchronization is implemented by time server on the software, so that the data from all the channels can be synchronized collect.The system realizes the communication with the data processing server, so that data can be transmitted to the server. The data is analyzed by the server after processing, then warning, positioning and other functions can be achieved according to these data.
