Description

technical field [0001] The invention relates to an infrared temperature measuring device in electric power equipment, in particular to an infrared temperature measuring device for non-contact online ultrasonic distance measurement and temperature compensation. Background technique [0002] Temperature is a physical quantity that indicates the intensity of molecular motion inside an object, and is one of the important parameters to determine the state of matter of an object. In the power system, most electrical equipments operate under the condition of high voltage and high current. In many power outage accidents, power outages and maintenance often occur due to local overheating of equipment. This not only affects the safe operation of the equipment and threatens public safety, but also brings significant economic losses to the power supply side. If early warning and quick measures can be taken in the early stage of the accident, it will be able to effectively avoid the occ...

Problems solved by technology

[0004] The present invention is to provide an infrared temperature measuring device based on ultrasonic distance measurement and temperature compensation. The device can not only solve the technical problem of real-time monitoring, but also aim at the infrared temperature measurement process. There is an error in the distance of the point to be measured. Ultrasonic ranging technology is used to obtain the distance from the measured object to the infrared thermometer online. According to the online measurement result, the temperature value measured by the thermometer is compensated or corrected to eliminate The additional error brought by the temperature measurement distance improves the accuracy of temperature measurement, and combines the infrared thermometer with precise positioning technology to realize online monitoring of multi-point temperature in space and save costs
