Embodiment approach 1

[0043] The following combination Figure 1 to Figure 7 Embodiment 1 of the present invention will be described. Embodiment 1 of this embodiment is an embodiment in which commands are forwarded by gateways in an intelligent building control network to reduce network congestion.

[0044] First, the general idea of ​​the first embodiment will be briefly described. That is, after analyzing the improvement method of the intelligent building control network in the prior art, it can be found that adding an IP controller between the gateway and the device can distribute the data of the gateway and increase the number of network controllable devices. However, this architecture does not reduce the actual commands issued by the gateway, nor does it reduce the data flow between the end-device networks. On the other hand, just adding multiple concentrator forwarding instructions inside the gateway does not optimize the processing function of the gateway. In Embodiment 1, a memory storin...

Embodiment approach 2

[0107] The following combination Figure 8 Embodiment 2 of the present invention will be described. Embodiment 2 is based on Embodiment 1, and further integrated processing of returned data is added.

[0108] First, the general idea of ​​the second embodiment will be briefly described. That is, considering the user's multicast command requirements in the intelligent building control network, the gateway needs to reply to the unicast and multicast commands respectively. For unicast data, the gateway can directly reply the data to the user; but for multicast commands, replying multiple pieces of data to the user is not the optimal way. This communication process is further optimized to reduce network congestion. For this requirement, the present invention provides Embodiment 2.

[0109] In this embodiment 2, the structure diagram of the gateway and the required data status table and Figure 5 The shown main processing flow is consistent with Embodiment 1, and will not be re...

Embodiment approach 3

[0120] The following combination Figure 9 Embodiment 3 of the present invention will be described. In Embodiment 3, an embodiment of the data processing flow of the gateway is added when the node actively sends data.

[0121] First, the overall idea of ​​the third embodiment will be briefly described. That is, considering the real-time requirements of alarm data in the intelligent building control network. For routine maintenance data, the time requirement range is relatively wide, and the gateway can periodically initiate an update, store it in the data status table, and return it to the user through the user's acquisition command; and the timeliness requirement for important data such as alarms is very high. High, if waiting for the user to obtain, it will cause adverse consequences if it is not processed in time.

[0122] For this requirement, this embodiment performs corresponding processing for different application types of data, especially real-time upload of alarm ...

Abstract

The invention relates to a gateway device and a data processing method, in particular to a gateway device and a data processing method used in an intelligent building control system. The gateway device is provided with a user communication interface for communicating with a user, a terminal-side communication interface for communicating with a terminal node, a memorizer for storing data related to equipment, and a processor for analyzing and processing data and user commands and controlling data interaction, wherein when receiving the data acquisition commands from the user through the user communication interface, the processor analyzes commands and checks whether the data stored in the memorizer meets specified requirements, if yes, the processor directly sends the data back to the user, otherwise, the processor asks for new data from the terminal node through the terminal-side communication interface and sends the new data acquired from the equipment back to the user.

Description

technical field [0001] The invention relates to a gateway device and a data processing method, in particular to a gateway device and a data processing method in an intelligent building control system. Background technique [0002] With the development of science and technology and the shortage of energy, intelligence and energy saving have become the development trend of modern building control systems. After realizing the communication performance of the terminal equipment, by monitoring the information of the sensors and controllers required for building management, all systems in the building (such as air conditioning systems, security systems, lighting systems, etc.) Integrated management. Thereby, the whole system can improve a comfortable indoor environment and user safety according to an appropriate control method, and can ensure building energy saving effect and manpower saving. [0003] Furthermore, in the context of the advancement of the Internet of Things, remo...
