Problems solved by technology

In the current building centralized smoke exhaust system, the outdoor main fan system and the indoor range hood basically use LoRa modules or NB-IoT modules and other high-penetration, low-speed network communication modules for communication connection due to interference such as floor concrete (wifi modules cannot Penetrating multi-layer floors), but if there is a range hood equipped with a wife module in the system, the system is often not compatible, so it is impossible to uniformly control the range hood equipped with a wife module

Abstract

The invention relates to a centralized smoke exhaust system for buildings, including a first-type indoor range hood, a public flue, and an outdoor main fan system; the first-type indoor range hood communicates with LoRa wireless transmission technology or NB-IoT wireless transmission technology The communication connection of the outdoor main fan system; the feature is that it also includes the second type of indoor range hood and a cloud server, the second type of indoor range hood communicates with the cloud server through a WIFI module, and the outdoor main fan system is connected through a wired network or wireless The network is also communicated with the cloud server; the first type of indoor range hood and the second type of indoor range hood both store the corresponding relationship between the indoor motor current gear-indoor motor speed-indoor range hood air volume; the outdoor The main fan system adopts the constant air volume control method to drive the indoor motors in the first type indoor range hood and the second type indoor range hood.

Description

technical field [0001] The invention relates to 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, the outdoor main fan system installed on the...
