Exchange server, system and method for addressing and transmitting data in control network

Abstract

The invention provides an exchange server, a system and a method for addressing and transmitting data in a control network, wherein the exchange server comprises a storage unit, a first processing unit and a second processing unit; the storage unit is used for storing a device map relation table and a source-sink relation table; the first processing unit is used for receiving a data packet sent by a source information node, inquiring the resource-sink relation table stored by the storage unit and obtaining and outputting the address of the exchange server, the ID of an end device and the information node number corresponding to a sink information node; the second processing unit is used for obtaining the address of a sink exchange server, the ID of the sink end device and the information node number, searching the device map relation table in the storage unit according to the ID of the end device corresponding to the sink information node when the address of the exchange server corresponding to the sink information node is the address of the exchange server, obtaining the address of the end device and sending the data packet with the sink information node number to the address. The invention simplifies the end device and saves the processing procedures of communication among end devices simultaneously.

Description

technical field [0001] The invention relates to a building automation system for buildings and modern homes, in particular to a switching server, system and method for controlling data addressing and forwarding in a network. Background technique [0002] Intelligence is a trend in the development of buildings and modern homes. With the expansion of building functions, the current intelligent building control content is more and more, and the control degree is becoming 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, the Building Automation System (BAS) emerged as the times require. A system of control, self-regulation and self-management. The so-called building mechanical and electrical systems usually include: heating, ventilating and air conditioning (HVAC), cold and heat source systems, water supply and drainage systems, lightin...

AI Technical Summary

Problems solved by technology

[0027] This centralized structure cannot form detailed seamless connections in different subsystems, and devices between different subsystems cannot realize complete communication (data addressing and forwarding) functions

They allow only limited status and control information to be transferred between different subsystems; not always accessible between end devices; systems cannot adapt their responses in real time based on overall system state

Of course, more complex control systems can be built through the use of gateways and custom programs, but they are usually not cost effective and the reliability of the system will suffer

Once the system is complete, the user cannot break away from the dependence on the vendor who provides the gateway and custom program
