Problems solved by technology

[0003] In the past, the control of the polarizer was mainly to control the rotation angle of the polarizer manually, which could not be linked with the antenna in real time during the experiment. Once the angle of the antenna changed and the polarizer could not be linked with the antenna, it wou

Example Embodiment

[0031] The present invention will be further described below through the drawings and specific embodiments.

[0032] Such as figure 1 As shown, a real-time linkage control system of polarizer and antenna. The control part is composed of a central controller, two reflective memory cards, two main controllers, two Ethernet switches, two PLC boards, and two controllers. ; The linkage part is composed of a linear polarizer, an elliptical polarizer, a focusing mirror, a rotating plane mirror and a servo motor, and the focusing mirror and the rotating plane mirror form the antenna plane mirror.

[0033] The linear polarizer is installed in the microwave emitting direction, the warp polarizer changes the microwave direction, and the elliptical polarizer is installed in the changed microwave direction, and the microwave direction is changed again and emitted to the focusing mirror, and then reflected to the rotating plane mirror. On, it is emitted to the plasma through the rotating plane mir

Abstract

The invention belongs to the field of plasma heating and particularly relates to a polarizer and antenna real-time linkage control system. The system comprises a control part and a linkage part, wherein the linkage part consists of a linear polarizer, an elliptical polarizer, a focusing mirror, a rotating plane mirror and a servo motor, the focusing mirror and the rotating plane mirror form an antenna plane mirror, the control part is composed of a central controller, two reflective memory cards, two main controllers, two Ethernet switches, two PLC boards and two controllers. The system is advantaged in that microwave polarization characteristics are changed in real time through linkage of the polarizer and the antenna, coupling efficiency of electron cyclotron waves and plasmas is guaranteed, and diagnosis equipment is prevented from being damaged. Through the reflective memory cards, the main controllers, the Ethernet switches and the PLC, the controller realizes real-time linkage control from a central control signal to the polarizer and the antenna, can perform efficient and accurate remote control in a complex experimental environment, and is simple in structure, high in response speed, high in control precision and stable in system.
