Intelligent building smoke exhaust system and control method thereof

Abstract

The invention discloses an intelligent building smoke exhaust system. The intelligent building smoke exhaust system comprises range hoods arranged on different floors, and further comprises a cloud platform capable of communicating with an outdoor main control device; each range hood comprises a fan and is provided with a Lora module; and the outdoor main control device capable of adjusting the target air volume of the range hoods is arranged at the top of a public flue and communicates with the Lora modules through signal receiving transmitters. The intelligent building smoke exhaust system has the advantages that the outdoor main control device of the smoke exhaust system can realize target air volume adjustment of the range hoods through mutual communication between the signal receivingtransmitters and the Lora modules, and in addition, the operation parameters and states of the system are checked online through the cloud platform. The invention further discloses a control method for the smoke exhaust system. According to the control method for the smoke exhaust system, the multi-gear adjustment change of the range hood of each floor can be realized, in addition, each floor hasa good oil smoke suction effect at a low start-up rate, meanwhile, the noise of a kitchen is low, when the start-up rate is high, the oil smoke suction effect is relatively good, and the noise of thekitchen is not high.

Description

technical field [0001] The invention relates to a building smoke exhaust system, in particular to an intelligent building smoke exhaust system and a control method thereof. Background technique [0002] Most of the current high-rise residences adopt the centralized smoke exhaust method. The indoor range hood is connected to the public flue through a smoke pipe and a check valve, so that the oil fume in the kitchen is discharged into the public flue through the indoor range hood through the smoke pipe. However, the cooking habits of the Chinese people with cooking fume and the current situation of large air volume and high wind pressure pursued by the existing range hoods make the pressure distribution in the public flue extremely uneven, and the pressure inside the flue is high. At the same time, due to improper installation of the smoke pipe and check valve, There are often problems with poor smoke exhaust and kitchen noise problems faced by users. In addition, for well-de...
