Abstract

A microcomputer control debugging method for high-voltage generator of x ray machine has its hardware structure composed of control circuit, inverse transformation circuit, high-voltage transformer and ball tube, and their connections are the control circuit output to be connected with the input end of high-voltage transformer through D / A converter, the output of the high-voltage transformer to the connected with the input ends of ball tube varying voltage and lamp filament current, and the output of the high-voltage transformer to be feedback to the input end of the control circuit through A / D converter; and the hardware part uses storage chip (RAM) with lithium cell to store training management data in the storage chip in advance and carries on the debugging for ball tube in the high-voltage generator of X ray machine by utilizing the storage chip.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a debugging method for reducing the number of times of use of a ball tube and increasing the service life in debugging a high-voltage generator of an X-ray machine. Background technique [0002] The high-voltage generator is an important part of the X-ray machine and is widely used in the field of medical instruments. At present, the domestic X-ray machine uses the tube to emit rays and expose the equipment to debug the equipment during the debugging process. The disadvantages are: Not only reduces the service life of ball tube, and the ray also endangers the health of staff. Contents of the invention [0003] In order to overcome the shortcomings of the previous X-ray machine in the debugging process and solve the actual production problems, the object of the present invention is to provide a microcomputer-controlled debugging method for the high-voltage generator of...
