Abstract

The invention relates to a program control X-ray diffractometer which is structurally characterized in that a conventional X-ray generating device and a goniometer are arranged in a shell; the drive shaft of the goniometer is connected with the transmission shaft of a servo motor; the signal output / input end of the servo motor is connected with a program control device; and an amplification board, a high-voltage board, a power board, an isolating board and an S7-200 PLC (Programmable Logic Controller) are arranged in the shell of the program control device wherein the port PORTO of the PLC is connected with a computer. Since the PLC is installed and triplex non-interfering isolating protection is adopted, the performance of the diffractometer is more superior, the fault rate is extremely low, and the service life of the complete machine is prolonged. An integrated motor is adopted as the motor for controlling the goniometer; a high-resolution magnetic encoder can automatically correct a very small movement position error by a high-precision full-closed loop vector drive servo system to ensure the degree of accuracy of the measuring result of the diffractometer. A recording unit realizes man-machine interaction, has complete protection function, and convenient and visualized operation and brings convenience for operators to use and judge fault information and the like. The diffractometer is suitable for the test, analysis and research work of the microscopic structure of matter.

Description

technical field [0001] The invention relates to an instrument for material microstructure analysis, in particular to an X-ray diffractometer device. Background technique [0002] X-ray diffractometer is an essential instrument for testing, analyzing and studying the microstructure of matter. The X-ray diffractometer is composed of an X-ray generating device, a goniometer, a data computing device and a control device. Since the control device is a control system composed of a single-chip microcomputer and 15 circuit boards, its high-voltage control unit is not electrically isolated from the management system. board, circuit control is complicated, it is not easy to debug and install, and the service life of the whole machine is reduced. The goniometer is the core device of the diffractometer. The stepper motor installed on the goniometer has no automatic error correction function, which affects the control accuracy of the goniometer. The text display of the recording unit c...
