LED indicator light control system, X-ray collimator is an important component of X-ray machine. Two sets of adjustable screen lead plates are used to define the X-ray exposure field in X-ray emission.Lies in its features, including PC and single chip microcomputer system, camera, motor drive circuit, two dc motors, camera installed in the led indicator light out of the mouth on the shell of light, and make your camera vision, camera to PC, PC output instruction transmitted by serial port to the single-chip microcomputer system, single chip microcomputer system after processing the data, the output through the motor drive circuit to control the led indicator light, and the longitudinal and transverse two dc motor are, inversion, two groups of driven by two dc motor regulation line lead plate movement.
