Abstract

The invention relates to anode rotating speed detection of an X-ray generator and belongs to the technical field of X-ray generators. An anode rotating speed detection device of the X-ray generator stops to output alternating-current power to an alternating-current motor in one time period, acquires a sensing voltage signal generated in the time period, and measures frequency of the sensing voltage signal, thereby achieving detection of the anode rotating speed. According to the invention, the anode rotating speed detection is simple, direct, precise, convenient and highly-efficient.

Description

technical field [0001] The invention belongs to the technical field of X-ray generators, and relates to the detection of the rotational speed of the rotating anode of the X-ray generator, in particular to an anode rotational speed detection device and an anode rotational speed detection device for realizing the detection of the rotational speed of the anode through the frequency detection of the induced voltage of the main winding of the AC motor. A detection method, and an X-ray generator including the anode rotational speed detection device. Background technique [0002] X-ray generators are widely used in various devices that use X-rays, for example, devices that use X-rays to expose and image, and have a very large impact in the field of medical imaging. [0003] figure 1 Shown is a schematic diagram of the basic structure and principle of the X-ray generator. In an X-ray generator, X-rays are usually generated in a vacuum bulb. The X-ray generator mainly includes a ca...
