Description
Technical field
The utility model belongs to the control device of accurate vibroseis, is specifically related to accurate vibroseis is carried out the accurate control module of the man-made explosion of High Accuracy Control.
Background technology
Predict earthquake, at first want to monitor the variation of earthquake preparation district underground structure transitivity.The ruinous earthquake of China mainly occurs in the dark place of underground 5-20Km, understand this regional detailed structure, monitor the dynamic change of this regional structure transitivity, whether breeding earthquake judging this area, and and then predictably the shake be very significant.But will be all sidedly, definitely, high-resolution ground, dynamically monitor that the underground structure in an area and change in physical are difficult, main difficulty is from earthquake source.
Accurate vibroseis has time, place, source signature and clearly determines for the earthquake focus, can repeat, install and use characteristics such as in extensive range, be particularly suitable for forecasting earthquake need the application that underground fine structure research and dynamic change thereof are monitored is carried out in the earthquake hazardous location.Accurate vibroseis is used for the dynamic surveillance underground structure, and the rule of research earthquake preparation, generation, development provides a kind of valid approach for capturing earthquake prediction.Accurate earthquake controllable earthquake focus system is to carry out initiatively earthquake study on monitoring, explores new, effective the forecast earthquake key equipment of approach.
Realize High Accuracy Control, need the signal of a core, specialty to take place and control system accurate vibroseis.Existing universal signal generating Instrument can't satisfy the designing requirement of accurate vibroseis.Its mainly show can't with the gps time strict synchronism, can't export the diversity of excitation wave, and can't keep aspects such as the high precision of excitation wave and high duplication.
The utility model content
The utility model provide a kind of high-precision, be exclusively used in that seismological observation field signal takes place and the accurate control module of the man-made explosion of control, its can realize with high precision GPS clock synchronously, and be that benchmark produces the output of high-precision pulse train with the 10M clock, realize that the high-power threephase asynchronous motor of control drives eccentric vibrating mass rotation accurately, thereby the vibrations of traction ground synchronous can be implemented smaller power and carry out remote seismic event transmission.
The technical scheme that the utility model adopted is as follows:
A kind of accurate control module of man-made explosion, it is characterized in that comprising a gps clock module, this gps clock module connection is provided with a master control circuit board, this master control circuit board connection is provided with a control interface board, and this control interface board is connected with power interface, communication interface and Electric Machine Control interface.
