Detailed Description
The single-wharf simulated geomagnetic field measurement transverse induction magnetic field Ziy system is composed of a single-side transverse geomagnetic simulation coil, a high-precision geomagnetic simulation power supply, a magnetic sensor array and a control computer, and is shown in fig. 3.
Unilateral transverse geomagnetic simulation coil: the single wharf is laid on the single wharf and used for generating a transverse simulated geomagnetic field; high-precision geomagnetic analog power supply: as a stable and high-precision constant current source, the power supply is used for supplying power to the transverse geomagnetic simulation coil; magnetic sensor array: the device is paved at the bottom of the XC station wharf, and the magnetic field value of the standard measurement depth (the standard depth below a ship waterline) in different states of electrification, non-electrification and the like is measured; the control computer: and controlling a high-precision geomagnetic simulation power supply to electrify the coil, collecting a magnetic field value of the magnetic sensor, and finally obtaining a standard measurement depth transverse induction magnetic field Ziy through calculation and analysis.
Taking an N-S direction single wharf as an example, the working principle of simulating the geomagnetic field to measure the transverse induction magnetic field Ziy is divided into the following two conditions according to the bilateral symmetry of a ship:
one, to naval vessel of bilateral symmetry
For ships with bilateral symmetry, a schematic diagram of measuring a transverse induction magnetic field Ziy by using a unilateral coil to simulate a geomagnetic field is shown in fig. 4, (1) is a schematic diagram of measuring a double-wharf, geomagnetic simulation coils are symmetrically laid on the left side and the right side of the ship along the longitudinal direction of the ship to form a transverse magnetic field relative to the left side and the right side of the ship, an underwater magnetic sensor measures that a magnetic field value generated by a coil at the port of the ship to be measured is a, and a magnetic field value generated by a coil at the starboard of the ship to be measured is b; in order to separate the measurement in the two steps in the step (1), a geomagnetic simulation coil is laid at the same position only on the left side in the step (2) in the graph of fig. 4 and is electrified, the value of a magnetic field generated by the coil on the port side of the ship to be measured is a1, and the value of a magnetic field generated by the coil on the starboard side of the ship to be measured is b 1; laying geomagnetic simulation coils at the same position only on the right side in (3) in fig. 4, wherein the value of the magnetic field generated by the coils on the port side of the ship to be tested is a2, and the value of the magnetic field generated by the coils on the starboard side of the ship to be tested is b 2; the left and right are measured separately and then superposed, and the result is consistent with the result of measurement (1) in fig. 4, then the following expression is given: a = a1+ a2 and b = b1+ b2, and a = b is because the ship and the laid geomagnetic simulation coil are symmetrical left and right, wherein a, b, a1, a2, b1 and b2 generate magnetic field values for the coils under the ship port and the ship starboard.
Assuming that a ship is anchored at a geomagnetic simulation coil symmetry center (wharf symmetry center), according to the symmetry of a magnetic field generated by the coil and the symmetry of the ship, the method comprises the following steps: a1= b2, a2= b1, the formula being collated to yield: a = a1+ b1, b = a2 + b2, a = b.
Because the ship induction magnetic field and the external magnetic field are in a linear relation, namely H = k H (wherein H is the ship induction magnetic field, H is the magnetic field generated by the external magnetic field such as the earth magnetic field or a coil simulation, and k is a proportionality coefficient), because the ship is symmetrical left and right, the proportionality coefficient k left = k right, namely the magnetic fields Ziy induced by the ship on the left and right sides under the uniform geomagnetic field are the same, namely the uniform geomagnetic fields on the left and right sides are equal ZiyL=ZiyR. As shown in fig. 4, at standard measurement depths, the magnetic sensors measured ship-induced magnetic fields a = ka, B = kb, a1= ka 1, B1= kb 1, a2= ka 2, and B2= kb 2; and further arranging to obtain A = A1+ B1, B = A2 + B2 and A = B, wherein A, B, A1, A2, B1 and B2 are induced magnetic field values under the port and starboard of the ship measured by the standard measuring depth magnetic sensor under the action of a certain external magnetic field.
Through the analysis, the simulation of the uniform geomagnetic field to obtain the induction magnetic field can be realized by laying a single coil for measurement, the left and right symmetrically laid coils can be replaced, namely the ship induction magnetic fields A1 and B1 are obtained by measuring the single coil, and the transverse induction magnetic field A, B of the ship under the uniform geomagnetic field can be calculated.
After the single coil is used for replacing the symmetrical coil to be laid, the magnetic fields generated by the coils on the port side and the starboard side are asymmetrical, so that the port side induction magnetic field and the starboard side induction magnetic field of the ship are different under the action of the single coil, and the steps of measuring the transverse induction magnetic field of the ship at the standard depth by the magnetic sensor are as follows:
1) reading the measured value (background magnetic field) H of the magnetic sensor before the ship enters the XC station (without the ship) and under the condition that the coil is not electrified0Left and right H0Right;
2) reading the measured value (background magnetic field + coil electrified magnetic field) H of the magnetic sensor before the ship enters the XC station (without the ship) and under the condition that the coil is electrified1Left and right H1Right;
3) after the ship enters XC station (with ship), and the coil is not electrified, the measured value (background magnetic field + ship magnetic field) H of the magnetic sensor is read2Left and right H2Right;
4) after the ship enters the XC station (with the ship), under the condition that the coil is electrified,reading the measured value (background magnetic field + ship magnetic field + coil energizing magnetic field + ship induction magnetic field) H of magnetic sensor3Left 1, H3Right 1;
5) respectively calculating to obtain transverse induction magnetic fields generated by single coils under the port and starboard of the ship:
ziy left = (H)3left-H2Left) - (H1left-H0Left);
ziy right = (H)3Right-H2Right) - (H1Right-H0Right).
6) Finally, calculating to obtain a ship transverse induction magnetic field under the uniform geomagnetic field (equivalent to a transverse induction magnetic field obtained by symmetrically laying coils and simulating the uniform geomagnetic field):
ZiyL1=ZiyR1left + Ziy right of Ziy.
And finally, the purpose of simulating uniform geomagnetic field to measure the ship transverse induction magnetic field Ziy can be realized in any course in a single wharf by combining the steps of generating a simulated geomagnetic field through a unilateral transverse geomagnetic coil, respectively measuring and converting by using a magnetic sensor to obtain standard depth transverse induction magnetic fields under the port and the starboard of the ship, and performing superposition calculation on the port and the starboard.
Secondly, aiming at ships with asymmetric left and right
According to the linear relational expression H = k H of the induction magnetic field and the external magnetic field of the previous section of ship, if the ship is asymmetric left and right, the proportionality coefficient k is not equal to k right, and the following results are obtained: a1 is not equal to B2, A2 is not equal to B1, A is not equal to B, namely, the magnetic fields Ziy induced by the port and starboard ships under the uniform geomagnetic field are different: ziyL≠ZiyR，
In this case, the problem of the unilateral transverse geomagnetic simulation coil can be solved by turning the direction and energizing, as shown in fig. 5, a schematic diagram of a left-right asymmetric ship measurement principle is shown, and fig. 5 (1) is a schematic diagram of a dual-code head (symmetrically laid geomagnetic simulation coils) measurement. In the N-S directional wharf, assuming that the ship is at the same position relative to the geomagnetic simulation coil, the geomagnetic simulation coil is positively charged when the ship is heading N, and a geomagnetic field in the right direction is generated, as shown in (2) in fig. 5; when the ship S is heading, the coil is negatively charged to generate a geomagnetic field in the left direction, as shown in (3) in fig. 5, the geomagnetic field is converted to a standard depth feature point, and finally, the transverse induction magnetic field Ziy can be obtained through superposition calculation.
For ships with asymmetric structures, the steps of measuring the transverse induction magnetic field of the ship at the standard depth by the magnetic sensor are as follows:
1) firstly, measuring an induced magnetic field of a ship at a standard depth under the action of a coil when the ship is parked at an N course, wherein the generated magnetic field is still asymmetric due to the fact that the coil is still a single coil, the measuring steps are the same as those of a left-right symmetric ship, and the transverse induced magnetic field of the N course ship under the left and right boards of the ship at the standard depth is obtained through the measurement of a magnetic sensor:
ziy left siden=（H3Left side ofn－H2Left side ofn）－（H1Left side ofn－H0Left side ofn）；
Ziy right siden=（H3Right siden－H2Right siden）－（H1Right siden－H0Right siden）。
2) Secondly, the ship is turned to the course at 180 degrees, and the ship transversely induces a magnetic field under the starboard and the starboard of the ship at the standard depth under the action of the coil when the ship is parked at the S course by the same principle:
ziy left sides=（H3Left side ofs－H2Left side ofs）－（H1Left side ofs－H0Left side ofs）；
Ziy right sides=（H3Right sides－H2Right sides）－（H1Right sides－H0Right sides）。
6) Finally, calculating to obtain a ship transverse induction magnetic field under the uniform geomagnetic field (equivalent to a transverse induction magnetic field obtained by symmetrically laying coils and simulating the uniform geomagnetic field):
transverse induction magnetic field Ziy under ship portL2= Ziy left siden+ Ziy left sides；
Transverse induction magnetic field Ziy under starboard of shipR2= Ziy right siden+ Ziy Rights；
By the method, the direction-adjusting and electrifying measurement is carried out in the N-S single wharf, the measurement of the asymmetric ship transverse induction magnetic field Ziy can be realized, and particularly, the first elimination of the ship can be realized in the N-S course aiming at the N-S single wharf commonly used for magnetic treatment.
Third, simulation calculation and model test
Through modeling simulation, the effect of measuring the transverse induction field Ziy of a certain ship by using the unilateral geomagnetic simulation coil is shown in fig. 6, and as can be seen from fig. 6, compared with the induction field measured by using the unilateral geomagnetic simulation coil under the uniform geomagnetic field, the induction field obtained by using the unilateral geomagnetic simulation coil has the advantages of consistent shape, equivalent amplitude and higher measurement precision.
The effect of measuring the physical model transverse induction field Ziy by using the scaling single-side transverse geomagnetic simulation coil is shown in fig. 7, the test result of the physical model is consistent with the simulation result, and compared with the induction field measured by using the transverse geomagnetic simulation coil under the uniform geomagnetic field, the induction field obtained by using the transverse geomagnetic simulation coil has the advantages of consistent shape and equivalent amplitude, the feasibility of the single-side transverse geomagnetic simulation coil measuring Ziy method in the text is verified, and the engineering requirement can be met.
