Multi-channel detector

Abstract

The invention relates to a multi-channel detector including an oscillator group, a data acquisition module, a data interface unit, a filter amplifier module and an industrial control computer; the data acquisition module includes a data acquisition module, and the data acquisition module is provided with an output interface; the oscillator group contains oscillators, and the oscillators are connected with the data acquisition module through signal lines; the output interface is connected with a corresponding input terminal inside the data interface unit through a signal line; the filter amplifier module includes a filter amplifier, the filter amplifier is connected with a corresponding output terminal inside the data interface unit through a signal line, and the filter amplifier is connected with a corresponding terminal inside a high-speed AD acquisition card through a signal line; the high-speed AD acquisition card is connected into an input port of the industrial control computer through a signal line.

Description

technical field [0001] The invention relates to a detection device, in particular to a multi-channel detection instrument. Background technique [0002] At present, on-line or off-line flaw detection of various non-ferrous metals, ferrous metal pipes, rods, wires, wires, and profiles has become more and more common. There are not many, and the sensitivity of detecting defects of metal pipes, rods, wires, wires, and profiles, such as surface cracks, dark seams, slag inclusions, and opening cracks, is not high. How can we produce modular operations and provide multiple displays? Models, and fool-proof devices that apply fully digital design technology have become people's expectations. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art and proposes a multi-channel detector. The detector uses an alternating current of a certain frequency to pass through the detection coil. When the test piece is close to the coil, the geo...
