Description

Предмет изобретени  - способ измерени  земного магнитно о пол  при 1К) феррозонда.The subject matter of the invention is a method of measuring earth magnetically about a floor at 1K) of a fluxgate.

Изобретенны способ отличаетс  от известных тем, что отклонение икдикаторс при положении оси феррозонда в иаправ.теиии общего вектора магнитного пол  Т компенсируетс  электрическим током ве:гичипы (, направл емым в расположенную на феррозонде измерительную обмотку, и затем, после поворота зонда па 180°, вновь компенсируетс  током },, величина об.дего вектора напр женности магнитного пол  Г /2 (2-Ь)Эта особеиность способа позвол ет устранить погренп-юстн измерений , выз.ываемые пестабп.тьностью источников электрического питани .The invented method differs from the known ones in that the deviation of the indicators when the axis of the fluxgate is located in the right direction of the common vector of the magnetic field T is compensated by the electric current ve: gyc (to the measuring winding located on the flux probe), and then after the probe rotated 180 °, again compensated by current}, the magnitude of the length of the vector of the magnetic field strength G / 2 (2-b). This specificity of the method makes it possible to eliminate power measurements caused by a variety of electrical power sources.

Устройство дл  измерени  земного магнитного по.т  описываемым сгк) состоит из мапштонасыпгенпого зонда, теодолита и компепсатора (измерител  тока).A device for measuring the earth's magnetic point (described by sgk) consists of a mapton probe-magnet probe, a theodolite and a compappator (current meter).

Зонд соедин етс  с трубой теодолита так, что его магнитна  ось располагаетс  параллельно оси ипструмепта. Поворотами в обеих п.тоскост х зонд устанавливаетс  в таком положении, при котором егоThe probe is connected to the theodolite tube in such a way that its magnetic axis is parallel to the axis of the instrument. By turning in both parts of the probe, the probe is set in such a position that its

ось совпадает с направ;1ением обще1о вектора магнитного пол  Т. В пзмерительную обмотку подаетс  ток I, такой велпчины, чтобы стрелка индикатора устанавливалась на 0. После поворота зонда на 180 током , снова производитс  установка стрелки индикатора на 0.the axis coincides with the direction; the total vector of the magnetic field T is detected. A current I is supplied to the measuring winding, such that the indicator arrow is set to 0. After rotating the probe 180 current, the indicator arrow is set to 0 again.

П р е д м е т изобретени PREAMETE OF THE INVENTION

Способ измерени  земного магнитного нол  при помопш феррозонда , о т л и ч а ю нг и и с   тем, что, с нелыо устрапе1П1  погрешностей измерени , вызываемых нестабильностью источников электрического питани , отклонение индикатора прн положении оси феррозонда в направлении общего вектора мапгитного пол  Т комненсируетс  электрическим током величины I,, направл емым в расположенную на (еррозоиде измерительную обмотку, и затем, после поворота зонда на 180°, вновь компенсируетс  током Ь; величина общего вектора напр ж-енности магнитного пол  . (L--l,)The method of measuring terrestrial magnetic zero with the help of a fluxgate, a tl and h and ng, and with the fact that, with small measurement errors caused by instability of electrical power sources, the deviation of the prn indicator of the position of the fluxgate axis in the direction of the common vector of the magnetic field T is compensated with an electric current of magnitude I ,, directed to the measuring winding located on the (Yerrozoid), and then, after the probe is rotated 180 °, is again compensated by the current L; the magnitude of the total magnetic field vector voltage ( L - l,)
