Methods of network deployment and data transmission of building automation system (BAS)

Abstract

The invention discloses a method of network deployment of building automation system (BAS), comprising an exchange server with independent addressing of IP address, a gateway, and terminal equipment, wherein the terminal equipment is connected with the port of the gateway; the method of network deployment further comprises carrying out data transmission between the gateway and the exchange server through carrier networks, wherein the data is carrier network protocol data. The carrier networks comprise communication networks according with general packet radio service (GPRS), wireless LAN (WLAN) or 802.11b criterion. Compared with the prior art, the methods have the following advantages: (1), the data communication between the gateway and the exchange server is carried out through carrier networks so that the whole wiring process of the BAS is more simple and convenient and the reforming process is much easier; (2), the communication protocol of data transmission of the BAS is simplified, and the transmission efficiency of the system is improved.

Description

technical field [0001] The invention relates to a building system, in particular to a networking method of a building automation system and a method for data transmission therein. Background technique [0002] Intelligence is an inevitable trend in the development of building construction. With the expansion of building functions, the current intelligent building control content is more and more, and the control degree is more and more complex. In order to meet the requirements of the building environment, reduce energy consumption, improve residential comfort and realize the scientific management of buildings, Building Automation System (BAS) came into being. The system performs automatic detection, automatic control, automatic adjustment and automatic management. [0003] With the continuous development of electronic technology, communication technology and network technology, the building automation system is constantly upgraded and updated with the continuous increase ...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the structure of the above-mentioned building control network system based on IP technology that the connection between the access device and the terminal device can usually adopt a variety of established standards, and the communication protocol can be selected according to the relative positional relationship between the two or the system bus relationship; As for the access device and routing device, since there may be only one routing device in the entire building, and multiple access devices are installed at the same time, if the above-mentioned wired Ethernet connection method is used, complex wired lines must be arranged in advance. , and after the line is erected, the location of the routing equipment is changed, the location of the access equipment is changed, or the network transformation such as the increase or decrease of the access equipment is performed, and the project consumes a lot
