Embodiment 1

[0056] Such as figure 2 As shown, the constant air volume control system of the public flue in the building of this embodiment includes a constant air volume control system including a cloud server 1, and a data acquisition module 2 installed on the target device in the building and a communication connection with the data acquisition module 2 Cellular communication module 3; target equipment includes indoor range hoods and / or outdoor units;

[0057] Among them, the cellular communication module 3 includes but is not limited to CAT1 modules, NB-IoT modules, 2G modules, 3G modules, and 4G modules. Of course, with the development of technology, the cellular communication modules can also include 5G modules and 6G modules. and other modules, as long as the cellular communication module can ensure stable communication performance between the cloud server 1 and the target device.

[0058] The data acquisition module 2 is communicatively connected with the cellular communication m...

Embodiment 2

[0121] The method for controlling the constant air volume of the public flue in the building in this embodiment is implemented by using the method for controlling the constant air volume in the public flue in the building in Embodiment 1.

[0122] Such as Figure 4 As shown, the constant air volume control method of the public flue in the building of the present embodiment includes:

[0123] S101. The data collection module collects the working state data corresponding to the target device, and calculates the actual air volume data corresponding to the target device according to the working state data;

[0124] S102. The data acquisition module also sends the working status data to the cellular communication module, and the cellular communication module reports the working status data to the cloud server;

[0125] S103. The cloud server calculates and obtains the target air volume data corresponding to the target equipment on each floor according to the working status data, a...

Abstract

The invention discloses a constant air volume control method and system for a public flue in a building. The constant air volume control system includes a cloud server, a data acquisition module and a cellular communication module; the data acquisition module is used to obtain the actual air volume data of an indoor range hood The cloud server is used to calculate the target air volume data of the indoor range hood according to the working status data and send it to the cellular communication module to be sent to the data acquisition module; the data acquisition module is used to adjust the corresponding indoor air volume data according to the actual air volume data and the target air volume data. The working status of the range hood. In the present invention, a CAT1 module is used to form a control system with a cloud server as the center, so that the communication delay is low and the communication performance is stable; the operating state of the range hood on the upper and lower floors is automatically adjusted according to the operating rate of the range hood and the resistance of the flue to realize Constant air volume operation avoids the occurrence of oil fume backflow.

Description

technical field [0001] The invention relates to the technical field of networking control, in particular to a method and system for controlling the constant air volume of a public flue in a building. Background technique [0002] At present, smart buildings mainly rely on adjusting the indoor range hoods of each household to a fixed high-speed operation to discharge the oil fumes to the public flue. However, this air volume control method has the following defects: (1) oily fume from the public flue is easy to flow back into the family; (2) the gear position of the indoor range hood cannot be automatically adjusted according to the operating rate of the public flue; (3) the established Local area networks such as LoRa (a wireless communication technology) have problems such as unstable communication performance and dead spots in network coverage; (4) The communication control delay is about 3-5 seconds, which cannot meet the actual use needs of users and reduces the user's c...
