Design of an Intelligent Optical Fiber Grating Temperature Measurement System for Electrical Equipment

Abstract

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.

Efficient design and implementation of a distributed temperature sensor for field apparatus

“…The above studies can achieved realtime measurements to a large extent with a certain measurement accuracy. However, the processing architecture based on an acquisition board requires a special personal computer (PC) and host processing software [22], which greatly affects its cost and application scenario.…”
