Description

technical field [0001] The invention relates to the field of temperature real-time monitoring devices, in particular to a high-precision detection device for temperature instrument signals. Background technique [0002] The joint temperature of substation equipment is an important feature to measure whether the power equipment is working in a healthy state. If the temperature is too high, it will affect its normal operation. It will cause a large amount of heat, cause a large-scale power outage, and even cause a fire. It is precisely because of the importance of the temperature of substation equipment that most substations still use artificial selective infrared thermometers to monitor the temperature of substation equipment at all times. Temperature conditions to ensure its normal operation. When the artificial selective infrared thermometer is used for temperature measurement, the data noise is large, the accuracy is low, and the high temperature abnormal data cannot be f...

Problems solved by technology

However, for remote villages with poor network signals, the wireless temperature measurement method has great shortcomings. The signal is unstable and the data is often interrupted. It cannot effectively detect the temperature of the substation equipment in real time, which can easily lead to accidents. Therefore, there is an urgent need for a high-precision detection device for temperature instrument signals to replace wireless signal monitoring. For remote villages with poor network signals, effective real-time monitoring of substation equipment temperature
