　　Application of ATE400 Wireless Temperature Measurement Online Monitoring System and Passive Temperature Measurement Technology in Power Internet of Things

　　The ubiquitous power Internet of Things can achieve interconnection of various energy services, but it requires strong data support. Among them, passive temperature measurement technology for power can play an important role in real-time sensing data collection based on the ubiquitous power Internet of Things, accurately improving the operating temperature data of the measured electrical equipment. Electrical equipment needs to operate within a reasonable temperature range in order to maintain normal functioning. The core advantages of using this temperature measurement method mainly include the following points: firstly, acoustic meter temperature measurement is an analog quantity, and the numerical value is easily affected by environmental interference, such as electromagnetic waves, mechanical vibration, and physical parameter deviation of the crystal itself after a certain period of harsh on-site operation. The temperature measurement of RFID temperature sensors is a digital quantity and comes with its own verification function. The second issue is that the communication between the sound meter temperature sensor and the reader is simple analog communication, which has poor anti-interference ability. Interference may occur from the same frequency signal source, mechanical vibration, etc., and it is difficult to distinguish when receiving incorrect signals; RFID temperature sensors can work in frequency hopping mode to avoid continuous interference on the same frequency. Even if interference is indeed received, the value is determined to be invalid through the checksum and discarded. The above causes problems such as missing digital IDs, regular maintenance, poor anti-interference ability, and difficulty in installation and debugging of the sound meter. The third issue is that CT based temperature measurement products require the integration of multiple chips and devices, as well as power rings, which are bulky and have poor reliability. The RFID temperature sensor product has all circuits on one chip, which is compact, flexible, and highly reliable.
