Communication system for fresh air system and method for establishing communication system

Abstract

The invention discloses a communication system for a fresh air system. The communication system comprises a plurality of subsystems. Each subsystem corresponds to one indoor area. Each subsystem comprises a detector and a plurality of fresh air ventilators which are in wireless communication connection with the detector through the same communication frequency, wherein the detector can sequentially send detection data to the fresh air ventilators of the same subsystem through time division multiplexing of the same communication frequency. The subsystems are different in communication frequency. The communication system solves the technical problem of communication disorder existing in a fresh air system with multiple split type fresh air ventilators, one-to-many communication can be accurately conducted, the network structure of the communication system can be simplified, and authenticity of sensing data collection can be improved. The invention further discloses a method for establishing the communication system through a remote controller, equipment searching, communication frequency correcting and pairing can be conducted only through key operation, the communication system establishing difficulty is greatly lowered, and the situation that professionals need to establish the communication system is changed.

Description

technical field [0001] The invention relates to the technical field of fresh air, in particular to a communication system and a debugging method for a fresh air system. Background technique [0002] The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. The air supply system processes (such as filtration, disinfection, sterilization, oxygenation, heating, etc.) The turbid indoor air is exhausted to the outside, so as to achieve ventilation through "one in and one row". Small-scale fresh air systems generally only need to be equipped with one fresh fan (fresh fan is a cavity purification device that can circulate air indoors and outdoors), while large and medium-sized fresh air systems need to be equipped with multiple fresh fans. In order to achieve automatic control of fresh fans, Sensors are needed to collect indoor air state parameters, such as temperature, humidity, PM2.5 value, formaldehyde, VOC value, etc. ...

AI Technical Summary

Problems solved by technology

However, the communication frequency of fresh air fans is uniform when they leave the factory. Large and medium-sized fresh air systems need to be equipped with multiple fresh air fans. If the entire fresh air system still uses a unified communication frequency for sensor data transmission, it will cause disorder in the communication system. The detectors send sensing data to the same fresh air fan at the same time, and the fresh air fan cannot judge which detector should receive the sensing data
