Ethernet based building controller

Abstract

The present invention relates to a kind of Ethernet-based building controller (abbreviated as EBC), comprising: an embedded CPU as a core working module; running and developing an engine module with dynamic C language in the embedded CPU, including a plurality of parallel The calculation algorithm module is used to explain and execute the lower-level configuration software control strategy; the Ethernet interface module connected with the embedded CPU is used to communicate with the monitoring computer or other EBC; the serial connected with the embedded CPU Line communication interface for long-distance data communication with smart devices. The invention has strong anti-interference ability, can run off-line, and has large information carrying capacity. It communicates with the monitoring computer using ModBus / TCP protocol, and communicates with other EBCs using UDP protocol. Due to the adoption of the event-based message exchange method, the building controllers can obtain fast exchange of information with less traffic occupation, ensuring real-time control.

Description

technical field [0001] The invention relates to a direct digital controller in the field of intelligent buildings, in particular to a building controller based on TCP / IP, which is applied to the monitoring of electromechanical equipment in the field of intelligent buildings. Background technique [0002] With the continuous development of human society, various types of buildings play an increasingly important role in human life and work. With the deepening of modern research on building automation and the popularization of various electronic and network products, the degree of automation of internal equipment in some office buildings or household buildings has also been continuously improved. In order to fully and effectively develop the potential of related equipment in buildings, improve the overall performance of building control systems, reduce equipment operation energy consumption and system operation and maintenance costs, intelligent controllers for monitoring elect...

AI Technical Summary

Problems solved by technology

There are already many kinds of intelligent controllers in the prior art, such as Honeywell's DDC (Direct Digital Controller), which mainly uses serial bus technologies such as RS485. During engineering installation, separate wiring is required, which not only requires a large amount of construction work, but also The anti-interference ability is poor, and the integrated wiring of some buildings has been completed, and repeated construction and wiring have brought a lot of inconvenience to users. On the other hand, the current DDC does not support communication between controllers. DDC with processing capacity leads to many types of equipment, and users need more types of spare parts
