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, the child node of the current range hood judges whether a main draught fan is started or not according to broadcast information of the main node of the last cycle host, if the main draught fan is started, the step S3 is executed, and if the main draught fan is not started, the step S4 is executed; S3, all the child nodes send current state updating information upwards at regular intervals, so that the host obtains startup information, and then the step S5 is executed; and S4, the child node of the current range hood judges whether the current range hood is at the broadcasting moment or not according to the broadcasting information of the last cycle, if the current range hood is at the broadcasting moment, the step S2 is executed after broadcasting is finished, and if the current range hood is not at the broadcasting moment, the current child node actively reports starting information so that the host can obtain the starting information, and then the step S5 is executed. The central flue system 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 an even distribution of flow 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 ...
