Abstract
The invention discloses a micro-seismic signal collection system. The micro-seismic signal collection system comprises a sensor module, a signal regulation module, an ADC (Analog to Digital Conversion) module and an upper computer which are sequentially connected. According to the micro-seismic signal collection system disclosed by the invention, data can be analyzed and processed through the upper computer according to a micro-seismic signal collected by the sensor module, thus an accident or a natural disaster can be early warned, and the loss brought by the disaster can be reduced to a large extent. The micro-seismic signal collection system disclosed by the invention has the advantages tat the collection and transmission data volume is large, the transmission speed is quick, the reaction is sensitive, the anti-jamming ability is strong, and the reliability is high.
Description
Technical field
The present invention relates to data-signal and gather the field, specifically is a kind of microseismic signals acquisition system.
Background technology
Along with developing rapidly of global economy and science and technology research; The micro seismic monitoring technology has also obtained application development fast at home and abroad; A lot of fields all utilize the monitoring in real time of be correlated with of this system, like mine (mine), tunnel, petroleum drilling, prevent stealing into another country, motor car engine malfunction monitoring, footsteps identification etc.The mine the rock landslide takes place before, bridge before fracture, some small vibrations omens all can take place before collapsing in the tunnel; Just can take place that big accident property is caved in afterwards etc.; The loss that has brought life and property of accident has all brought huge injury for country and society.If but we can monitor these microseismic signals timely, harm and probability that minimizing accident greatly takes place, the farthest minimizing accident of early warning in early stage or the loss of disaster to a certain extent even.Aspect the contingent regional location of early warning microseism disaster and concrete time, challenge still a lot, there in face of present countries in the world expert, still have a lot of difficult problems to have to be to be solved.On the time that the early warning microseism takes place, also be difficult in the effective measures that analyze data parallel that can be for reference in the monitoring result especially.And for disaster and the accident of forecasting that any rock burst problem is brought, spatial domain time and regional location are the two large problems that people pay close attention to and demand urgently foreseeing forever.Have only in technological early warning, to solve simultaneously and could farthest reduce the loss that disaster is brought.
Summary of the invention
The technical matters that the present invention will solve provides a kind of microseismic signals acquisition system, and its data amount transmitted is big, transmission speed fast, be quick on the draw, antijamming capability is strong, reliability is high.
