Description
Technical field
The present invention relates to a kind of protected against the effects of immersion anti-electric surge Multi-functional portable microseismic signals fidelity box, belong to On Microseismic Monitoring Technique field, be specifically related to one and meet IP67 standard, there is the anti-electric surge of protected against the effects of immersion, effective reduction electromagnetic interference (EMI), the Multi-functional portable microseismic signals fidelity box of quick connection feature, is applicable to the fields such as on-the-spot micro seismic monitoring and test.
Background technology
The energy that microseism (microearthquake) refers to rock self accumulation in subrange acquires a certain degree, and brings out the crack initiation of rock interior, destruction under the disturbance in the external world, and the energy of accumulation is the microseismic activity of generation with the release of elastic wave form.On Microseismic Monitoring Technique is a kind of new geophysical prospecting technology grown up the nineties in 19th century, for the control of the dynamic disasters such as rock burst, impulsion pressure, landslide provides new governing measure and technology.At present, oneself has an opencast mining of and the important means of other great rock engineering disaster monitorings and forecast through becoming oilfield prospecting developing, mineral resources exploration and exploitation, power station Slope Construction, mine.
Microseismic signals fidelity box between sensor and Acquisition Instrument is one of key factor affecting micro seismic monitoring, and it is directly connected to the quality of the microseismic signals that Acquisition Instrument receives.If transmitting procedure microseismic signals is subject to extraneous strong interference, cause the microseismic signals data that microseismic system server analysis is wrong, impact is carried out correct monitoring and prediction timely to power station Slope Construction, mine strip mining transformation and other great rock engineering disasters by this, thus can increase the loss of casualties and property.Guarantee the normal work of microseismic signals fidelity box, effectively can reduce the interference that micro seismic monitoring signal is suffered in transmission engineering, be conducive to determining microquake sources position accurately, in time the generation of prevention engineering project disaster.
On-the-spot micro seismic monitoring, same workplace often needs speed and the acceleration signal of monitoring rock burst simultaneously, this needs to prepare quality test of pile simultaneously and acceleration type sensor provides envelope eapsulotomy device, at present, mostly microseismic signals fidelity box is to be divided into velocity profile and acceleration type microseismic signals fidelity box according to sensor type, often needs the type often changing microseismic signals fidelity box according to engineering situation during onsite application.In addition, sensor cable, Acquisition Instrument cable are by PCB(Printed Circuit Board) connection terminal is connected with microseismic signals fidelity box circuit board.Because different cable specification is different, water joint is difficult to it closely to fix, and when causing cable to be pullled by machinery or personnel, PCB connection terminal junction loosens and even disconnects, cannot normally monitor microseismic activity signal, need often to overhaul and reconnect.Work on the spot bad environments, rather dark in chamber, stuffy, and the installation of envelope eapsulotomy box with change work high above the ground often, each operation is wasted time and energy, in long chamber, installment work forms very large threat to the healthy of site operation personnel and life security, is therefore necessary further improvement.
