The known method and device for positioning a punch (patent RU №2132428, MPK E 02 F 5/18), namely, that detect the signal emitter located on the punch or next to it, using two antennas located on the surface of the earth, as a signal emitter using a rotating magnetic field, and magnetic field rotate so that the plane of rotation of the vector of the magnetic moment PMthe emitter is perpendicular to the axis of the punch, receive signals in the near zone, where the predominant reactive power field, find the position of this plane in space with directional properties of the antenna and by its orientation determines the direction of the axis of the punch, and with a minimum of two samples shall luchtel, and the module of the gradient and cubic dependence of the field strength on the distance determine the distance to the emitter.

The known device for determining the location of the punch (patent RU №2132428, MPK E 02 F 5/18) includes an emitter of electromagnetic waves, located on the punch or next to it, two directional antennas, the receiver, the transmitter and the indicator light located on the surface, while the outputs of the receiving device are connected to the inputs of the transmitter and its output connected to the indicator, receiving antennas whose outputs are connected to the inputs of the receiver, mounted on a common base on the distance d so that the plane of the zeros of their diagrams of coincided, and the base is made with the possibility of transfer. As the emitter using the rotating magnetic field generator.

The disadvantages of the known method and device should be attributed to the relatively low accuracy of determination of the direction of the punch due to the fact that the module of the field gradient at small angles of deviation from the true direction to the emitter tends to zero, and the inability to determine the roll. Under the roll in this case refers to the angle of rotation of the punch around its longitudinal oomu invention is a method for positioning a punch in the soil (the decision to grant a patent dated 10.01.2003, on the application for invention No. 2002102815/28 from 31.01.2002, MPK E 02 F 5/18). According to the method (Fig.1), according to which the use is located on the punch 1 or adjacent emitter 2 excite a rotating magnetic field, rotate so that the plane of rotation of the vector of the magnetic moment of the emitter was perpendicular to the axis of the punch, find the position of this plane in space with directional properties of antennas 3, 4, located on the surface of the earth, determine at least two plane spaced above the punch. Each of the planes is determined by three points, in which the relative delay between the signals of equally oriented antennas placed at these points is zero. Find the line of intersection of these planes, and then find the point of intersection of this line with the known plane of rotation of the magnetic moment of the emitter. This line of intersection of planes with zero delay signal coincides with the axis of the punch, and the point of intersection of this line with the plane of rotation of the vector of the magnetic moment coincides with the center of the emitter. Thus determine the location and pitch drift. In the space above the punch 1 (Fig.2) determine the I magnetic field in the antenna 3, 4 placed in this plane. To determine this plane equally oriented antennas 3, 4 are placed on the same vertical line and synchronously moving them in the space above the punch, find two points a and b on the surface, in which a signal delay between the antennas is equal to zero. The line drawn through these points is the line of intersection of the found plane with a horizontal surface and coincides with the course of punch.

Consider the feasibility of the method and device in a specific example.

In the proposed method for determining the roll punch use a rotating magnetic field, the emitter of which is rigidly connected with the punch 1 (Fig.4). Take the plane in which lie the vector of the magnetic moment PMand the axis of the punch (Fig.4). Since the vector of the magnetic moment rotates around the axis of the punch, and the plane along with lying on her lines of force will rotate. The initial phase rotation vector of the magnetic moment PMcorresponds to the position vector RM0and rigidly connected with the position of the punch, in which the roll PA RM0will be definitely within 360° to depend on the anglerotation of the punch and rigidly associated emitter around the longitudinal axis, i.e., the roll punch. The initial phase of the signal, excitation rotating magnetic field in the emitter 2, is rigidly connected with the initial phase of the rotation vector of the vector of the magnetic moment, i.e., with position vector RM0that does not depend on the roll punch and serves as a reference point when measuring the delay of signals induced in each antenna. When this relative delay is defined as the difference between the delays of the signals in the antennas found relative to the initial phase rotation vector of the magnetic moment. Information about the initial phase of the signal exciting the emitter and rigidly associated with the initial phase rotation vector of the magnetic moment PMpass from the emitter by using the processing unit and transmitting the initial phase 10.

Definition of roll is produced as follows. Over the punch 1 (Fig.4) feature on one vertical two equally oriented spaced antennas 3, 4. Synchronously moving them in the space above the punch 1, find the point on the surface, in which the relative zapustiv the maximum signal level in the antenna. Obtaining the maximum level of the signal corresponds to the orientation of the antenna relative to the lines of force of the rotating magnetic field at which the measured delay will be true. Next, measure the delay in one of the antennas and it recalculates determine the roll punch.

The device operates as follows. The signals induced in the antennas 3, 4, proceed to the inputs of a two-channel receiver with 5 privatie, the output signal of the transmitter 6 is supplied to the indicator 7. Simultaneously, the signal from the outputs of the receiving channels of the receiver 5 is fed to two inputs of the meter lag 8, whose role can perform conventional phase detectors. The output signal from oscillator 2 is fed to the input of the processing unit and transmitting the initial phase 10, and with its output to the third input of the meter lag 8, where it is used as a reference signal, the output signal from the meter lag arrives at the lag indicator 9.
