Non-contact three-dimensional thermal displacement detection system and application thereof

Abstract

The invention provides a non-contact three-dimensional thermal displacement detection system and application thereof. The non-contact three-dimensional thermal displacement detection system comprises a binocular camera, a laser range finder, a visual processing cabinet and a computer control system, and the binocular camera and the laser range finder conduct signal collection on displacement; and then the collected signals are transmitted to the visual processing cabinet, and the visual processing cabinet transmits the signals to the computer control system. The embodiment of the invention provides a non-contact three-dimensional thermal displacement detection system and application thereof, the non-contact three-dimensional thermal displacement detection system provided by the invention adopts an artificial intelligence technology, realizes a measurement mode of parameters such as boiler expansion amount and pipeline displacement amount, can perform automatic early warning on safe operation of equipment, improves the intelligent level of the power plant, improves the safety production coefficient of the power plant, gains economic benefits for the power plant, and guides digital construction and intelligent operation of the power plant.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a non-contact three-dimensional thermal displacement detection system and its application. Background technique [0002] During the working process, thermal power plant boilers are faced with countless tests of heat expansion and heat release contraction. The boiler body or corresponding parts will be deformed and displaced due to heat or heat release. If the stress generated exceeds the corresponding parts can bear Without the ability to adapt, there may be accidents that affect the safe operation, which seriously threatens the safe operation of coal-fired power plants. At present, boilers in power plants are equipped with mechanical pointer expansion indicators to measure the deformation caused by the thermal expansion of the boiler. Manual inspections are used to record the data of the boiler wall and the monitoring points of the steam-water system on site, and then perform offline proc...
