Description
Известны способы .многочастотной электроразведки, требующие одновременной непрерывной запитки источника пол токами двух частот, одна из которых используетс в качестве опорной частоты дл исключени вли ни первичного пол .Methods of multi-frequency electrical exploration are known that require simultaneous continuous powering of the source by fields of two frequencies, one of which is used as a reference frequency to eliminate the influence of the primary field.
В описываемом способе электроразведки две частоты используютс дл уплотнени измерительного канала и компенсации уровн помех . Первичное поле возбуждают автоматически переключаемым через определенные промежутки времени генератором, работающим на двух или более частотах. Принимаемый сигнал измер ют одновременно и,; всех рабочих частотах так, что в промежутки времени, когда поле имеет одну рабочую частоту, осуществл ют определение и автоматическую компенсацию уровн помех на другой рабочей частоте.In the described method of electrical prospecting, two frequencies are used to compact the measuring channel and compensate for the level of interference. Primary field excite automatically switched at regular intervals by the generator operating at two or more frequencies. The received signal is measured simultaneously and ,; all operating frequencies such that, at intervals when the field has one operating frequency, the determination and automatic compensation of the interference level at another operating frequency is carried out.
На чертеже изображена блок-схема устройства, работающего по описываемому способу.The drawing shows a block diagram of a device operating according to the described method.
Задающий генератор /, генерирующий частоту /j, и делитель (или умножитель) 2 частоты, с которого снимаетс частота /о поочередно с помощью переключател 3 подключаютс к оконечному усилителю мощности 4, питающему генераторную рамку 5.The master oscillator (generating frequency / j) and the divider (or multiplier) 2 frequencies, from which the frequency / o is picked off alternately with the help of switch 3, are connected to the final power amplifier 4, which supplies the generating frame 5.
Сигнал информации, снимаемый с приемной рамки б, проходит через усилитель 7 и попадает на две параллельные цепочки 8 и .9, включающие фильтры и измерители сиг.нала частоты /i и /з. Выходные напр жени , гни taeмыe с указанных цепочек, пропорциональные измер емым параметрам, через переключатели 10 и //, работающие сиихро.чно с переключателем 3, поступают на входы дифферепииалымх регистраторов 12 и 13.The information signal, taken from the receiving frame b, passes through the amplifier 7 and falls on two parallel chains 8 and .9, which include filters and meters of the signal frequency / i and / h. Output voltages, taemye from these chains, proportional to the measured parameters, through switches 10 and //, working siichro.
Каждый из этих регистраторов состоит из двух включенных в мостовую схему ламп М и включенного в измерительную диагональ измерительного или самспищущего прибора 15. Регистрат(||) фиксируетEach of these recorders consists of two M lamps included in the bridge circuit and a measuring or self-testing device 15 included in the measuring diagonal.
