Communication method of central flue system and central flue system adopting communication method

Abstract

The invention discloses a communication method of a central flue system and the central flue system adopting the method. The communication method comprises the following steps that S1, a user starts a range hood; S2, a child node of the current range hood judges whether a main fan is started according to broadcast information of a main node of a last cycle main machine, if the main fan is started, step S3 is executed, and if the main fan is not started, step S4 is executed; S3, all child nodes send current state updating information upwards at regular intervals, so that the main machine obtains startup information, and then step S5 is executed; and S4, the child node of the current range hood judges whether it is at a broadcasting moment at present according to the broadcasting information of the last cycle, if the it is at the broadcasting moment, step S2 is re-executed after broadcasting is finished, and if it is not at the broadcasting moment at present, the current child node actively reports startup information so that the main machine can obtain the startup information, and then step S5 is executed. The central flue system provided is operated by adopting the communication method.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a communication method for a central flue system and a central flue system using the method. Background technique [0002] The central flue system generates power through the main fan placed at the top of the public flue, and cooperates with the adjustment of the check valve connected to the public flue to achieve uniform flow distribution on each floor, so as to achieve the purpose of smooth smoke exhaust and low noise . [0003] Due to the complex wireless environment of the building, the attenuation of the wireless signal is very large. For floors above 10 floors, the bottom floor smoke machine cannot directly establish communication with the roof fan. For the smoke collection and exhaust machine system, the network structure generally adopts the hand-in-hand connection method, also called the bus connection method, that is, the method of uploading information to t...
