Problems solved by technology

[0004] The information of node devices includes multiple levels such as nodes, endpoints, clusters, and attributes from outside to inside. The relationship between the levels is one-to-many, and the whole is similar to a tree structure. For the query of node device information, ZigBee gateway It is also carried out one by one according to this hierarchical relationship, but due to the low transmission rate of ZigBee, when the number of node devices in the ZigBee network is large, due to the limitation of transmission rate, the collection of node device information by ZigBee gateway is often not timely enough. timeliness of control

Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0056]The present invention provides a system for ZigBee gateways to query node device information, which is used for ZigBee gateways to query and collect node device information of node devices such as smart home devices, so as to realize the control and management of smart home devices. The present invention implements In the example, the node device is a smart home device. The system for ZigBee gateway querying node device information of the present invention comprises: to-be-queried queue, unfinished list, completed list and stored list, namely a plurality of lists or queues are set, and are used to carry out the node device of different query progress It is stored, and when the node device queries the node device information, it can manage the node device more clearly.

[0057] The information of node devices includes information such as nodes, endpoint...

Abstract

The invention relates to the field of network gateways, and discloses a system for ZigBee gateways to query node device information, including queues to be queried, unfinished lists, completed lists, stored lists, protocol stack application threads, and node management threads. The queue is used to store the node devices of the node devices that have not yet performed information query; the unfinished list is used to store the node devices that are in the process of information query; Extract information; the node management thread is used to perform query process jump and result processing according to the query status of node device information, and interact with the protocol stack application thread and the Internet side application program. The invention also discloses a method for the ZigBee gateway to inquire about the node device information. The present invention can collect node equipment information in an orderly and rapid manner.

Description

technical field [0001] The invention relates to the field of network gateways, in particular to a system for ZigBee gateways to query node device information and a method for ZigBee gateways to query node device information. Background technique [0002] With the development of the Internet of Things technology and the popularity of smart home devices, more and more smart home devices have entered ordinary homes, most of which have applied ZigBee (Zigbee protocol) technology. The ZigBee gateway is the core of the ZigBee network. A ZigBee network is formed through the ZigBee gateway. Smart home devices join the ZigBee network and become a node device of the ZigBee network. The ZigBee gateway can control the node device. [0003] However, the ZigBee network has a limited range and cannot be directly connected to the Internet, so it is impossible for users to remotely view and control smart home devices. In order to meet the needs of users for remote viewing and control, it ne...
