Temperature measurement is crucial for industries such as power, microwave, semiconductor, and medical. With the development of technology, temperature measurement methods are gradually upgrading and accuracy is gradually improving. Currently, commonly used temperature measurement methods include electronic sensing methods such as thermistor and thermocouple, as well as infrared temperature sensing methods. Thermistor and thermocouple methods use electronic principles for measurement, and data transmission is also done using metal wires. These temperature measurement devices have high measurement accuracy, but they do not have anti-interference capabilities for temperature measurement in power and microwave facilities, especially in the microwave industry where metal objects are not allowed to be placed; Although infrared temperature measurement method is a non-contact visual temperature measurement method, it measures the heat radiated from the surface of an object, and the measured result is the average temperature of a large area of the heat source, which cannot reflect the temperature of the specific location of the measured object, and the temperature measurement accuracy is relatively low.
Ang optical fiber temperature measurement device for photovoltaic cell modules includes a photoelectric conversion module, a fluorescent temperature measurement probe, a bare optical fiber, a conductive optical fiber, an ST-FC adapter, a heat shrink tube, and a groove opened on the photovoltaic cell module. The groove extends to the edge of the photovoltaic panel module, and the end of the bare optical fiber has a fluorescent temperature measurement probe. The bare optical fiber with the fluorescent temperature measurement probe is led out along the groove on the surface of the photovoltaic cell module to the edge of the photovoltaic cell module. The fluorescent temperature measurement probe is tightly fixed in the groove on the surface of the photovoltaic cell module, and the bare optical fiber passes through the conductive optical fiber The ST-FC adapter is connected to the photoelectric conversion module, and a heat shrink sleeve is fitted at the junction of the conductive optical fiber and the groove edge of the photovoltaic cell module. The photovoltaic cell module is installed on the back plate, and the water-cooled cooling system is connected to the external water supply system through an electromagnetic valve. The photoelectric conversion module is connected to the electromagnetic valve through a temperature control unit, and the temperature control unit adjusts the opening of the electromagnetic valve based on the temperature signal output by the photoelectric conversion module.
