[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Refer to Figure 1, this specific embodiment adopts the following technical solutions: A cable lead seal crack detection system based on an eddy current technology big data algorithm, including an instrument host 1, a charger 2, a standard block 3, a base 4, a probe 5, a high-frequency connecting wire 6, a data wire 7, data 8, and a shock-proof carrying case 9. The charger 2, the standard block 3, the base 4, the probe 5, the high-frequency connecting wire 6, and the data wire 7 are placed in the grooves inside the shock-proof carrying case 9, and the data 8 is placed on the inner side of the lid of the shock-proof carrying case 9.

[0026] It should be noted that a display screen 1-1 and a plurality of control buttons 1-2 are provided on the front of the instrument host 1.

[0027] It should be noted that the display screen 1-1 adopts a color liquid crystal display screen, with multiple backlights available, and the backlight intensity is adjustable.

[0028] It should be noted that the control buttons 1-2 include a confirmation key, an exit key, a function key, a lock key, an increment key, a right shift key, and a power key.

[0029] It should be noted that the side wall of the instrument host 1 is connected to the high-frequency connecting wire 6, and the high-frequency connecting wire 6 is connected to the probe 5.

[0030] It should be noted that the probe 5 adopts probes with various different specifications and can be replaced according to needs.

[0031] In addition, there are two standard blocks 3. The first standard block is an aluminum material standard block, and the second standard block is a copper material standard block.

[0032] This specific embodiment is a non-destructive testing method based on the principle of electromagnetic induction and is applicable to conductive materials. If a conductor is placed in an alternating magnetic field, there will be an induced current in the conductor, that is, eddy current is generated. Due to the changes in various factors of the conductor itself (such as conductivity, magnetic permeability, shape, size, and defects, etc.), the induced current will change. By using this phenomenon, the properties, states, and the existence of defects of the conductor can be judged.

[0033] In this specific embodiment, the instrument host and the probe are connected by a high-frequency connecting wire. If continuous monitoring exceeds 60 minutes, it needs to be recalibrated. After powering on, on the measurement interface, press the function key to move the cursor to calibration, and press the confirmation key to enter the "air calibration" interface. At this time, place the probe in the air for 2 seconds (keep the probe away from magnetic interference sources). The interface is as Figure 3 shown. After 2 seconds, press the confirmation key to complete the air calibration. At this time, keep the probe in place. When the "standard block one calibration" interface appears on the instrument, place the probe vertically on the center position of the surface of the first standard block (aluminum block) and make the probe fully and stably touch for 2 seconds. The interface is as Figure 4As shown. Press the OK key after 2 seconds to complete the calibration of Block 1. At this time, keep the probe in place. When the "Calibration of Block 2" interface appears on the instrument, move the probe vertically to the center position of the surface of Block 2 (copper block) so that the probe and the block are in full and stable contact for 2 seconds. The interface is as Figure 5 shown. Press the OK key after 2 seconds. At this time, still keep the probe in place and wait for the system to automatically return to the measurement interface.

[0034] When measuring in this specific embodiment, press any key on the startup interface to enter the measurement interface. The screen displays the interface saved before the last shutdown: if the interface saved last time is a Chinese interface, the screen displays a Chinese interface; vice versa. The interface is as Figure 6 shown.

[0035] Press the function key in the measurement interface to move the cursor to the save item, and press the OK key to enter the save interface. If the system has automatically selected the save item, directly press the OK key to enter. As Figure 7 shown.
