Problems solved by technology
The complex and open signal transmission and acquisition system composed of through-wall flanges, signal lines, and back-end amplifiers is extremely susceptible to interference from strong electromagnetic equipment such as plasma discharge, high-voltage power supply, and auxiliary heating; complex shielding and grounding also give The investigation of interference and abnormal signals brings great inconvenience
In addition, the huge installation well pipe and the front protection shutter not only occupy precious window resources, but also bring potential safety hazards of vacuum leakage

The invention discloses a built-in remote control photoelectric detection system. The photoelectric detection module includes a shielding shell in a vacuum environment, a miniature shutter installed at one end of the shielding shell, and a photoelectric detector and a module installed inside the shielding door. Digital conversion module, embedded control system and wireless transceiver module 1. The invention adopts wireless induction power supply and wireless communication module to replace the existing working mode of signal cable transmission signal, and only needs a small signal window to complete the digital transmission of measurement signal, greatly reducing the occupation of window space; Acquisition, amplification, and analog-to-digital conversion achieve high integration, reduced size, and reduced power consumption; unified shielding shell can achieve high-quality shielding and enhance the signal-to-noise ratio of measurement signals; miniaturized built-in modules can easily select the best observation. It can be installed at an angle, and can also be installed in hidden and narrow spaces, providing measurement data at special locations.
Description
technical field [0001] The invention relates to the technical field of photoelectric sensing, in particular to a built-in remote control photoelectric detection system. Background technique [0002] In the study of magnetic confinement fusion, high-temperature plasma is confined in an inner vacuum chamber by a strong magnetic field, and plasma radiation spectroscopy is often used to measure plasma parameters. The measurement bands of various observation systems cover the vacuum ultraviolet, soft X-ray and hard X-ray bands. The structures and functional principles of the related detectors are also very different, and the installation methods and observation positions are not the same; however, these detectors can be used. It belongs to solid-state photodetectors, and is mostly installed in the area of the device well tube close to the plasma. Since the detector needs to work in a vacuum environment, the electrical signal needs to be drawn out by means of a vacuum through-w...
