地电仪工作可靠性和抗干扰的研究

STUDY ON RELIABILITY AND ANTI-INTERFERENCE CAPACITY OF DIGITAL GEOELECTRICAL EQUIPMENT

摘要:

自动化的地电观测仪器在观测过程中,因受干扰有时会造成死机或复位等现象,使观测过程不能顺利进行.导致仪器不能可靠运行的原因中,电源的干扰和强电磁场的干扰是很重要的因素.增强仪器电源部分的抗干扰能力以及在电路中采用软、硬件的抗干扰措施能较明显地增强仪器的抗干扰能力,提高其工作可靠性.

Abstract:

Digital geoelectrical equipment controlled by microprocessor may be casually deadlocked or reset when measuring the apparent resistivity due to some interferences.Through careful analysis,it is found that the fundamental interferences are from pow er circuit and strong electromagne-tic filed,which reduce reliability of the equipment.Fortunately,the anti-interference capacity and reliability of the equipment could be evidently heightened by adopting software and hardw are improvement.
