Two-level inspection system for water leakage status of heating facilities

Abstract

The invention relates to a heating facility water leakage state two-stage inspection platform which comprises a first flow detection device arranged at a water inlet pipe of a heating facility and used for detecting the current flow of the water inlet pipe and outputting the current flow as a first flow; the first flow detection equipment is arranged at a water outlet pipe of the heating facilityand used for detecting the current flow of the water outlet pipe to serve as second flow to be output; the water leakage early warning equipment is respectively connected with the first flow detectionequipment and the second flow detection equipment, and is used for calculating the excess of the first flow exceeding the second flow and sending water leakage early warning information when the excess is greater than or equal to a limited quantity; and the water leakage identification equipment is respectively connected with the water leakage early warning equipment and the pixel point analysisequipment, and is used for sending a water leakage identification signal when the water leakage early warning information is received and the water trace information is received. According to the invention, the water leakage detection precision and automation level of the heating facility can be improved.

Description

technical field [0001] The invention relates to the field of water leakage inspection, in particular to a two-stage inspection system for water leakage status of heating facilities. Background technique [0002] The heating facility can directly install the stove that generates heat in it by means of a certain amount of space heating; it can also extract the air in it, heat it and then send it back; Exothermic. This higher temperature object is called a heating radiator. In order to make the heating radiator continue to release heat, the preheated fluid can be used to continuously flow through the radiator. This fluid is usually steam or hot water and is called "heat medium". After the heat medium is heated by the heat generating, heat collecting or heat exchanging equipment (heat source) located outside the space, it is distributed to each heating radiator with heating pipes. After the heat medium transfers part of the heat it carries to the radiator, it flows back to t...

Problems solved by technology

[0004] In order to solve the technical problem that the current heating facilities cannot self-check the water leakage status, the present invention provides a two-stage inspection system for the water leakage status of the heating facilities, which performs an instant alarm operation when water traces are detected in the heating equipment, wherein the background matching method is adopted , to determine whether the output image of the visible light camera has a position change due to the displacement of the visible light camera, and it is particularly important that a self-adjusting unit is also built in the visible light camera to automatically adjust the position according to the change of position Restoring; using a dual-stage filter mode and an adaptive binarization threshold adjustment mode, the effect of image preprocessing is improved; based on the preliminary detection results of the number of targets in the image, the timing and number of contrast enhancement processes for the high-definition image are determined, Thus avoiding the waste of computing resources
