“…The measurement range is fixed at ±1 V, the noise is less than 0.2%, and crosstalk between channels is less than 1%. We can remotely set gain-controlled attenuators in the IF modules and video boards to adjust the amplitudes of the DAQ input signals to match the fixed measurement range of DAQ system [12].…”

A: A 384 channels (24 vertical ×16 radial) Electron Cyclotron Emission Imaging (ECEI) system has been installed on Experimental Advanced Superconducting Tokamak (EAST). With the aid of advanced front optics, high spaital resolution around 1.1cm and flexible vertical coverage 30 ∼ 70 cm have been realized. The well-designed optics also provides a long Rayleigh length up to 70 cm even with an object length larger than 2.6 m. The electronic system has a wide immediate frequency (IF) bandwidth 2 ∼ 16.5 GHz, which enables a continuous radial coverage up to 25 cm. Benefited from advanced optics design and the wide IF bandwidth, the ECEI system with high spatial resolution can provide a large and continuous view field, especially in the radial direction, which is enough for the observation of the whole q = 1 surface. The comprehensive details of the ECEI system will be presented in this paper, along with some experimental results.

Today, domestic temperature monitoring systems usually use a master-slave multi-computer network composed of personal computers and single-chip computers. The single-chip microcomputer is used as a sub-computer to collect the temperature data of each sampling point. As a desktop computer, the PC is responsible for recording and displaying temperature and humidity, and centralized management. Since the conventional temperature measurement system cannot detect wavelength changes well, the temperature measurement system has problems such as low accuracy and stable operation. Therefore, an intelligent optical fiber grating temperature measurement system design for electrical equipment. The structure and characteristics of fiber grating and the principle of automatic temperature measurement of fiber grating components are introduced. Following the above principles, the temperature measurement system architecture is designed to include a data viewing layer and a remote monitoring layer in the storage layer. The results show that the total temperature change caused by the electrical equipment failure of the system described in this article is less than 1°C, and the total temperature change of the designed system is in the range of 2.5 to 3.5°C. The results show that the temperature error of the system described in this document is very small, and can accurately measure the automatic temperature of the glass fiber grid of electrical equipment.
