一种适用于简易震源的地震仪无线触发系统的设计和研究OA

Small-scale cable seismograph usually requires a cable as a shot line to connect the seismic source and central unit of seismograph.The length of shot line can be up to 200 meters or longer,and at least one additional worker is needed to worker to retract and release the shot line as well as move it with the shot point.Although wireless triggered system,such as the UE series of Seismic Source Company,have long existed,they are mainly used for large seismographs that use explosives or vibrator vehicles as seismic source.This equipment is large in size,rich in functions,and generally requires additional power supply.It is not practical for simple seismic sources such as hammer or drop hammer.Therefore,it is of great significance to develop a small-scale wireless triggering device that is battery powered and can be embedded into a large hammer for cable seismometers.The switch core circuit of trigger device designed and developed in this paper mainly includes STM32U5 series processors and wireless transceivers.And a wireless transceiver is added to the main control end of traditional seismograph,which deeply sleeps the entire system in idle state and only wakes up the processor when triggered by tapping.The battery life can reach 2.8 years,and it can save about 20%of labor costs when applied in seismic exploration operations.
