Description

Technical Field

At the same time, since the guide assembly 3 and the deviation corrector 5 are arranged to cooperate to accurately correct the deviation of the steel strip, it can ensure that the steel strip is stably fed during the detection process, thereby improving the accuracy and reliability of the detection;

[0048] It should be noted that the hardware system of the flatness detector 6 is mainly composed of the following parts:

[0049] CPU: MCS-51 microcontroller is usually used as the core processor.

[0050] Analog / digital converter: Such as the AD57412-bit successive approximation analog / digital converter, used to convert analog signals into digital signals.

The sensor coil is passed through an alternating current to generate an alternating magnetic field. When the steel plate to be tested is placed in it, eddy current is induced on the surface of the steel plate. The direction of this current is opposite to the direction of the current on the sensor coil, thus generating a new magnetic field on the steel plate, which is opposite to the direction of the original magnetic field, causing the equivalent impedance Z of the coil to change. The change in the flatness of the steel plate surface will affect the distance between the coil and the steel plate, thereby changing the impedance Z, and then reflecting the defects on the surface of the steel plate, realizing the detection of the flatness of the steel strip.
