[0029] The FS calculation control module is provided with an area calculation button and a sensitivity compensation button. The area calculation button is used to control and switch the optimal coil area under different preset frequency bands. The area value is calculated according to the FS calculation control module. If there is an error in the set optimal coil area, the sensitivity compensation button starts to work; the sensitivity compensation button is used to adjust the error within the preset area range. The sensitivity compensation button distributes compensation, and each time the compensation is based on ±0.1% of the preset area value, which is specifically reflected in the correction coil diameter range of ±1mm.

[0031] The single-chip control module is provided with a digital signal correction button and a tension signal correction button. The digital signal correction button is used to increase or decrease the preset signal and the actual signal according to ±0.1% per step. If the preset signal is greater than the actual signal, the actual signal is reduced by 0.1% on the basis of the actual signal. Otherwise, the actual signal is increased by 0.1%. The tension signal correction button is used to adjust the output tension. When the actual signal is greater than the required tension, the tension value is reduced. When the actual signal is less than the required tension, the tension value is increased.

[0036] The tension controller is located in the high-performance sensor coil, receives the mechanical signal transmitted by the single-chip control module and converts the mechanical signal, and adjusts the distance between the concentric auxiliary coils by using the deformation characteristics of the pull-sensitive resistor;

[0037] The high-sensitivity control module and the high-performance sensor coil work in coordination to adjust the coil area in real time, that is, the coil area is sensed in real time through the area calculation button and the sensitivity compensation button, and compared with the preset value, and the optimal detection result is coordinated through sensitivity compensation.

[0038] The present invention also provides a method for adjusting the area of an all-aeronautical electromagnetic sensor coil using the above system to achieve pull-through sensing control, the method comprising the following steps:

[0039] Step 1: Determine the size of the transmitting coil area based on the electromagnetic constitutive model and numerical simulation results to obtain the frequency band f The mapping relationship with the coil area S is: S=F(f);

[0040] Step 2: Embed S=F(f) into Python language to develop FS calculation control module. After the area calculation button is activated, the FS calculation control module can calculate the optimal area size according to the on-site test condition parameters. At the same time, the sensitivity compensation button is turned on to automatically enhance the signal strength according to the signal feedback.

[0041] Step 3: Open the single-chip microcomputer control module to convert and correct the digital signal transmitted by the FS calculation control module. Turn on the digital signal correction button and the tension signal correction button in sequence. The single-chip microcomputer control module transmits the tension information to the high-performance sensor coil.

[0042] Step 4: The tension controller receives the mechanical signal transmitted by the single-chip control module and controls the deformation of the pull-sensitive resistor between the double-layer concentric auxiliary coils. The pull-sensitive resistor can form radial inward and outward deformation according to the positive and negative tension, thereby changing the size of the coil area.
