Step S104, based on the preset current, the first primary side voltage and the second primary side voltage, determining the primary side equivalent eddy current resistance of the conductivity detection device.
The greatest difference between the conductivity detection device under water and on land (in air) is the difference in energy transmission medium between them. The air medium may be considered to have no charge flow therein caused by the electromagnetic field and thus need not be considered. However, in the case that the medium is liquid (such as seawater), since the conductivity of the liquid is far greater than that of air, the eddy current loss generated in the medium cannot be ignored, the equivalent circuit model of the corresponding conductivity detection device in the liquid medium is shown in fig. 3, and the eddy current resistance of the reaction seawater medium is introduced based on the equivalent circuit model of the conductivity detection device in the air medium (as shown in the dotted coil in fig. 3).

Optionally, based on the preset current, the secondary current, the angular frequency, the coil inductance, and the load resistance, the secondary equivalent eddy current resistance is determined by:
wherein, the liquid crystal display device comprises a liquid crystal display device,for the above-mentioned secondary side equivalent eddy current resistance, < >>For the preset current, < > for>For the secondary side current, +.>For the above angular frequency, +.>For the coil mutual inductance, the->The load resistor.
And step S110, determining the conductivity in the liquid environment according to the primary side equivalent eddy current resistance and the secondary side equivalent eddy current resistance.
In an alternative embodiment, the determining the conductivity in the liquid environment according to the primary side equivalent eddy current resistance and the secondary side equivalent eddy current resistance includes: obtaining primary side power according to the primary side equivalent eddy current resistance and the preset current; obtaining secondary side power according to the secondary side equivalent eddy current resistance and the secondary side current; obtaining a first conductivity based on the primary side power; obtaining a second conductivity based on the secondary side power; based on the first conductivity and the second conductivity, the conductivity in the liquid environment is obtained.
It should be noted that, the eddy current loss is mainly a power loss generated by an electromagnetic field in a liquid environment (such as seawater), and there is a certain relationship among the power loss, the electromagnetic field in the liquid environment, and the electrical conductivity. The primary side power and the secondary side power can be obtained under the conditions that the primary side equivalent eddy current resistance, the secondary side equivalent eddy current resistance, the primary side current (namely preset current) and the secondary side current are known. The specific calculation formula is as follows:

The first conductivity and the second conductivity may be determined, but are not limited to, by:

Alternatively, the first electric field strength and the second electric field strength may be obtained, but are not limited to, by:
wherein, the liquid crystal display device comprises a liquid crystal display device,representing the coordinates of any point in space, N is the number of turns of the transmitting coil, < >>Is a first order Bessel function, +.>Is the permeability of liquid (such as seawater), and +.>Is a variable->For the dielectric constant>For angular velocity +.>As imaginary factors, other variables are explained above and are not repeated hereSaid.
In an alternative embodiment, the obtaining the conductivity in the liquid environment based on the first conductivity and the second conductivity includes: calculating a conductivity difference between the first conductivity and the second conductivity; judging whether the conductivity difference is smaller than a preset difference threshold value or not; and obtaining the conductivity in the liquid environment based on the first conductivity and the second conductivity under the condition that the conductivity difference is smaller than the preset difference threshold value.
By the method, after the first conductivity and the second conductivity are obtained, the degree of difference between the first conductivity and the second conductivity is determined by calculating the conductivity difference between the first conductivity and the second conductivity, and the conductivity in the liquid environment is obtained based on the first conductivity and the second conductivity under the condition that the difference between the first conductivity and the second conductivity is not large, namely the conductivity difference is smaller than a preset difference threshold value, so that the purpose of calculating accuracy of the conductivity in the liquid environment is achieved.
Optionally, if the difference in conductivity is greater than or equal to the preset difference threshold, it indicates that the difference between the first conductivity and the second conductivity is greater, and at this time, if the conductivity in the liquid environment is determined based on the first conductivity and the second conductivity, a larger calculation deviation is easily caused. Thus, it is possible, but not limited to, obtaining a new first primary-side voltage of the conductivity detection device in air and a new second primary-side voltage of the conductivity detection device in a liquid environment under new current excitation in an open state of the secondary-side circuit of the conductivity detection device by changing the magnitude of the preset current in case the conductivity difference is greater than or equal to the preset difference threshold; determining a new primary-side equivalent eddy current resistance of the conductivity detection device based on the new preset current, the new first primary-side voltage, and the new second primary-side voltage; acquiring a new secondary side current of the conductivity detection device in the liquid environment under the excitation of the new preset current when the secondary side circuit of the conductivity detection device is in a channel state; determining a new secondary equivalent eddy current resistance of the conductivity detection device based on the new preset current and the new secondary current; and determining the conductivity in the liquid environment according to the new primary side equivalent eddy current resistance and the new secondary side equivalent eddy current resistance.
Optionally, when the conductivity difference is greater than or equal to the preset difference threshold, a new first conductivity and a new second conductivity may be obtained correspondingly based on the new primary equivalent eddy current resistance and the new secondary equivalent eddy current resistance (the same manner as the first conductivity and the second conductivity are obtained, which are not described herein), and the conductivity in the liquid environment may be obtained based on the new first conductivity and the new second conductivity.
In an alternative embodiment, in a case where the difference in conductivity is less than the preset difference threshold, obtaining the conductivity in the liquid environment based on the first conductivity and the second conductivity includes: and calculating an average value between the first conductivity and the second conductivity when the conductivity difference is smaller than the preset difference threshold value, and taking the average value as the conductivity in the liquid environment.

In the above manner, in the case where it is determined that the first conductivity and the second conductivity do not differ much, the average value of the above-described first conductivity and the above-described second conductivity may be calculated as the conductivity in the liquid environment, or the first conductivity may be regarded as the conductivity in the liquid environment, or the second conductivity may be regarded as the conductivity in the liquid environment.
Through the steps S102 to S110, the purpose of directly detecting the liquid conductivity in a special liquid environment (such as a deep water area) can be achieved, so that the technical effect of improving the accuracy of measuring the liquid conductivity in the special area (such as the deep water area) is achieved, and the technical problem of inaccurate conductivity measurement caused by the fact that the liquid needs to be taken out when the liquid conductivity in the special area (such as the deep water area) is measured in the related art is solved.
