Fault detection and positioning method for building centralized smoke exhaust system

Abstract

The invention relates to a fault detection and positioning method for a building centralized smoke exhaust system. The building centralized smoke exhaust system comprises an indoor range hood, a public flue outdoor host system, and a cloud server. The method is characterized in that the building centralized smoke exhaust system conducts fault detection and positioning through the steps that 1, any indoor range hood is powered on and started, and the building centralized smoke exhaust system is awakened; 2, the indoor range hood which is powered on and started sends the operation state information of the indoor range hood to the cloud server directly or through the outdoor host system; and 3, the cloud server analyzes and positions a fault according to the floor position information and the operation state information of the indoor range hood, and sends the fault floor position information and the service priority to maintenance service personnel. Compared with the prior art, the method has the advantages that the problems of low fault detection speed, low efficiency, inconvenience for inspection and the like of the indoor range hood in the prior art are solved.

Description

technical field [0001] The invention relates to a fault detection and positioning method of a building centralized smoke exhaust system. Background technique [0002] At present, most of the range hoods used in the kitchens of houses and apartments are independent. Holes in the windows or walls are used to set the exhaust port of the range hood. The oil fume is discharged directly from the outer wall, which will cause pollution interference to the residents on the upper and lower floors, and will cause oil pollution to the outer wall. At the same time, it will also affect the overall appearance of the building. [0003] With the high-speed development of economy, more and more high-rise residential buildings have sprung up like mushrooms after rain. In order to maintain the appearance and image of the entire building, in many high-rise residential buildings, a centralized smoke exhaust system for the building will be adopted for centralized smoke exhaust. The public flue, ...

AI Technical Summary

Problems solved by technology

[0005] 1. The position of the specific fault or function reduction machine mainly depends on the user's report for repair. When a certain indoor range hood has a function drop, it is often not found at the initial stage. When the user reports for repair, the fault is already serious;

[0006] 2. The naked eye inspection can only observe obvious faults on the surface of the machine, and the connection interface between the indoor smoke exhaust branch pipe and the public flue is faulty. It is inconvenient to observe the blockage faults in the gypsum board ceiling and the public flue;

[0007] 3. Machine and floor detection one by one, slow speed and low efficiency
