In the application process of fiber optic temperature sensing technology, both domestically and internationally, the focus is on sensor research and fiber optic temperature management. Portanto, fiber optic grating temperature sensors have become the key to research projects in fiber optic temperature sensing technology. No fiber optic distributed temperature measurement system, research on fiber optic temperature sensing technology needs to be integrated with fire prevention, multi-point temperature control, and other projects for comprehensive analysis, but its overall cost is relatively high.

The basic temperature measurement principle of point type fiber optic temperature sensors in practical applications is that the critical edge of the semiconductor absorption spectrum will change with temperature and move accordingly. It can establish effective analysis and judgment of the degree of change after the semiconductor chip undergoes light intensity processing. Além disso, the absorption rate of semiconductor media is directly related to the bandgap width of the semiconductor during the process of light absorption. After the temperature changes, thermal expansion and temperature changes will affect the vibration state of the crystal, causing changes in the actual width parameter of the bandgap and resulting in abnormal absorption spectra.

Under certain conditions, the thickness of the light source illumination varies. The projected light intensity needs to be measured for specific parameters with the help of It ddt RR I α α − − −=1 e (1) e22. Entre eles, R represents the power reflection coefficient of the entire light source illumination system, which is proportional to the refractive index, extinction coefficient, and incident angle of the material; D represents the actual thickness of the entire semiconductor structure; α represents the absorption coefficient of the semiconductor material itself. By combining actual measurement data, it is possible to effectively analyze the actual level of the corresponding system, and by combining the relationship between the light source wavelength determination function, calculate the integral over the entire wavelength range. Isso quer dizer, in practical operation, selecting an incident broadband light source and matching photodiodes can effectively calculate and analyze the transmitted light intensity, and the relevant parameters can also show different trends with changes in environmental temperature, effectively improving the overall efficiency of temperature detection work.

Implementação de Sensor de fibra óptica System in Power System Detection

In the hardware implementation of power systems, the operational level of switchgear is crucial, and technicians need to integrate circuit breakers to ensure that mobile carts and switchgear can play their actual value. Entre eles, the high-voltage switchgear itself has 6 contatos, one distributed on each of the three phases on the upper and lower sides, which can effectively improve the reliability of system operation and enable real-time monitoring and temperature measurement with the help of contacts. Portanto, it is necessary to improve the probe and circuit signal processing facilities during the temperature monitoring process of the high-voltage switchgear in the system, and to achieve the following points.

Primeiramente, select the light source. After the light is emitted from the light source, the transmittance intensity will gradually change with temperature changes through the action of the probe. With the help of a point type sensor de temperatura de fibra óptica, the intensity of the transmitted light can be monitored for temperature to ensure the implementation of the work. Portanto, technicians need to constrain the measurement range of sensors in the selection of light sources, and judge based on the temperature change of the critical edge of the absorption spectrum to effectively obtain a wider spectral width parameter. It should be noted that in terms of selecting the wavelength of the light source, sufficient parameter considerations should be made in conjunction with the absorption edge, and the parameters should be controlled between 864-908 nm to select more suitable parameters, lançando as bases para o desenvolvimento abrangente da detecção de expansão de intensidade de luz e trabalho de processamento de comprimento de onda central.

The most important thing is that the application of software systems should take CPU improvement as a prerequisite, and on the basis of integrated utilization efficiency, conduct centralized analysis and judgment on the quality of software process initialization operations, functional processing operation instructions, and timed interrupt function instructions, in order to reasonably improve control standards.

On the basis of comprehensive analysis and system optimization of point type fiber optic temperature sensors, the application process of sensors in power equipment monitoring has been tested in the structure of 10kV high-voltage switchgear, which can effectively form 9-point monitoring. On the basis of traditional technology, system calibration and experimental testing are carried out by directly placing the fiber optic sensor in the electric constant temperature box of the equipment, effectively meeting the temperature control efficiency. Durante o experimento, the temperature gradually increased from room temperature. The operator needs to measure the temperature and coefficient analog output of the constant temperature box at different temperature intervals, effectively integrate the temperature values, and improve the final processing effect. On the basis of the joint action of thermocouple thermometer and mercury temperature sensor, corresponding temperature parameters are obtained. After using thermocouple thermometers and mercury thermometers to detect temperature, it can be used as a reference value for the temperature of the constant temperature chamber.

In actual measurement work, in order to comprehensively understand the time stability of fiber optic temperature sensors during operation, attention should be paid to data feedback after continuous measurement, ensuring the selection of basic temperature control conditions, and based on this, obtaining differentiated measurement results of fiber optic temperature sensors formed by changes in time,

Além disso, sensors mainly use fiber optic technology, which is heat-resistant and can be directly placed in temperature control systems. By controlling the temperature between -20 para 125 ℃, the system can also operate normally.

After calibrating and testing the system installation system, it is necessary to ensure the actual level of application of the switchgear. O processo de instalação do chassi do sistema também precisa analisar a parte de baixa tensão do quadro, especialmente o feixe de luz e a estrutura do tubo que conecta o chassi e as sondas. Para garantir a pontualidade da eficiência do processamento, é necessário garantir que os parâmetros de flexão da fibra atendam aos requisitos reais durante o processo de instalação e evitar a mistura de fibras que afete a utilização da fibra. Geralmente, medir parâmetros de dados requer estabelecer uma relação de conexão através do barramento serial RS485 e conectá-lo na sala de monitoramento. Combinado com os dados acumulados durante a operação do software, testes e análises de temperatura são realizados em diferentes pontos para melhorar efetivamente o nível básico de alarme do sistema. No processo de aplicação do sensor, it is necessary to measure and analyze the temperature of high-voltage transmission cable joints. The number of monitoring measurements should be controlled at 20 ou mais, and a monitoring network should be established using RS485 to analyze and transmit information to different fixed points in the system, forming a monitoring structure. It is precisely because the system can measure the temperature of the contacts of the cable system, and if the temperature is high, it will give an alarm, which can to some extent avoid accidents.
