The present invention provides an electronic switch type main / auxiliary multi-channel ultrasonic acquisition system and electronic equipment. The acquisition system includes: N ultrasonic probes, N-way selection switches, an ultrasonic emission module, and an ultrasonic acquisition module for acquiring ultrasonic data; wherein, If the i-th probe is not set with an auxiliary channel, directly collect the ultrasonic data for the i-th probe; if the i-th probe is set with several auxiliary channels, divide the ultrasonic data fed back by one channel selection switch and one ultrasonic probe into several channels of ultrasonic data, Each channel of ultrasonic data is collected through the acquisition channel corresponding to each auxiliary channel; the auxiliary channel pointer is set for the i-th probe to set different gains for the i-th probe, and ultrasonic data with different gains are output through different acquisition channels. The invention avoids the problem of re-acquisition due to signal overload of a certain channel, and at the same time realizes that the probes and waveforms of different auxiliary channel signals from the same position are basically similar.
Description
technical field [0001] The invention belongs to the technical field of in-service inspection of nuclear power plants, and relates to an acquisition system, in particular to an electronic switch type main / auxiliary multi-channel ultrasonic acquisition system and electronic equipment. Background technique [0002] The safety of nuclear power plants is of paramount importance, and a comprehensive inspection and repair of nuclear power plants is required during each refueling period. Among them, the in-service inspection is one of the important contents. Ultrasonic flaw detection should be carried out on the welds of key equipment (such as pressure vessels, steam generators, main pipelines, etc.). Probes are arranged in four directions to conduct full-volume inspection of welds, so a scan requires 8-16 ultrasonic probes, and a multi-channel ultrasonic flaw detector is required. [0003] In traditional multi-channel ultrasonic testing instruments, there are often multiple probes...
