Problems solved by technology

Existing building automation systems generally adopt this hierarchically integrated system architecture. Sensors and actuators are connected through a bus communication network. Once a device is added or withdrawn from the system, the corresponding upper-level system must be modified. Inconvenience to parties and managers, such as regular software upgrades and redefinition of new system functions
This hierarchical architecture relies on every link in the entire system, especially the top-level processor, and needs to collect all information before making corresponding analysis, calculation and control decisions, which makes it difficult for the stability and efficiency of the system to meet certain requirements. application needs

Embodiment Construction

[0042] The present invention is described in detail below in conjunction with accompanying drawing:

[0043] On the one hand, the present invention discloses a building automation system based on a secondary network, such as figure 1 with figure 2 As shown, including: a primary information network and a secondary control network;

[0044] The first-level information network includes: a number of intelligent nodes for information transmission through network cables; each intelligent node is created corresponding to a set area in the building space;

[0045] The intelligent node is equivalent to a multi-core computer, which provides various control, management, and computing capabilities as a whole. Each intelligent node is created corresponding to a set area in the building space, and the information transmission between each node is realized through the network cable between the intelligent nodes, which constitutes the first-level information network of the entire building ...

Abstract

The invention discloses a building automation system and method based on a secondary network. The primary information network is composed of independent intelligent nodes, adopts an Ethernet network architecture for wired transmission, and has the capabilities of self-identification, self-organization, and self-coordination; The level control network is directly oriented to each system on site, and adopts a 433MHz wireless sensor network architecture to meet the measurement and control requirements of each system on site. The invention focuses on solving the specific problems of online plug-and-play, such as the reliability of information transmission of each system and the increase or decrease of equipment in the system integration process, and realizes the flat management of the building control network.

Description

technical field [0001] The invention relates to the technical field of building intelligence, in particular to a building automation system and method based on a secondary network. Background technique [0002] The building automation system is a building intelligent system with the richest content, the most complex control management, and the most intelligent devices in the intelligent building control system, and it is one of the most important components of intelligent buildings. At present, most of the building automation systems on the market adopt a layered structure model, mainly fieldbus topology. In simple terms, it can be divided into management layer, control layer and field layer. Existing building automation systems generally adopt this hierarchically integrated system architecture. Sensors and actuators are connected through a bus communication network. Once a device is added or withdrawn from the system, the corresponding upper-level system must be modified. ...
