Abstract

The invention relates to an infrared temperature measuring device based on the ultrasound ranging temperature compensation. Stepping motors in horizontal direction and vertical direction, an infrared temperature measuring unit, an ultrasound ranging module, a laser indicator and a positioning switch are arranged on a holder mechanical structure; the holder mechanical structure is connected with a calibrating module through the laser indicator and a control module; a calibrated parameter storing module, a control system and calibrating module, a system positioning interface circuit and the ultrasound ranging module are respectively connected with a central processing unit (CPU); the infrared temperature measuring unit sends the detected temperature value signal to the CPU, CPU sends the value signal to an upper computer through a wireless communication interface module. The infrared temperature measuring device can perform non-contact online temperature measurement on the to-be-tested points distributed at every position of the space; the infrared temperature measuring device is high in precision and quick in measuring speed; the structure design is reasonable, the infrared thermometer and the accurate positioning technology are combined, therefore, the online monitoring of multi-point temperature of the space is realized, and the cost is saved.

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...
