Embodiment Construction

[0042] The implementation of the present invention will be specifically described below.

[0043] In the broadcasting method of the present invention, in a power transmission network including a service terminal node, a convergence node, an access node, and an access gateway, the broadcast node is an access gateway or an access node, and correspondingly, the forwarding node is an access node or a convergence node, There are one or more convergence nodes. When a new convergence node or access node is connected to the power transmission network, or there is an emergency broadcast control signaling, active broadcast is adopted. During active broadcast, the broadcast node actively sends a broadcast frame, and the forwarding node Actively forward broadcast frames, and the rest use periodic broadcasts.

[0044] The present invention preferably provides two implementation solutions.

[0045] Option 1: Continue to use the existing broadcasting architecture.

[0046] like image 3 A...

Abstract

The invention discloses a broadcasting method and system. The power transmission network comprises a service terminal node, an aggregation node, an access node and an access gateway, wherein broadcastnodes are access gateways or access nodes, correspondingly, forwarding nodes are access nodes or aggregation nodes, one or more aggregation nodes perform active broadcasting and forwarding during broadcasting, the broadcast nodes actively send broadcast frames, and the forwarding nodes actively forward the broadcast frames. The invention also provides a broadcasting system, a network protocol isconfigured in the service terminal node, the aggregation node, the access node and the access gateway of the power transmission network, network data connection is established according to the networkprotocol, and the network protocol realizes the broadcasting method. According to the invention, an active broadcast process is defined, so that timely access of nodes or emergency broadcast controlsignaling is facilitated; the two schemes provided by the invention are suitable for different scenes, and can effectively process various active broadcasts.

Description

technical field [0001] The invention belongs to the technical field of power systems, relates to a broadcasting technology in a wireless sensor network of power equipment in a power transmission network, and is a broadcasting method and system. [0002] technical background [0003] As the main artery of the power system, the transmission grid undertakes the important function of long-distance and large-capacity power transmission. Therefore, it is necessary to effectively monitor the transmission network and collect relevant data, such as the monitoring of towers and substations. Specifically, this type of data is obtained by sensors, which are the source of terminal data. Sensors include wireless sensors and wired sensors, and wireless sensors include micro-power consumption and low-power consumption sensors. [0004] In the transmission network, the sink node collects the terminal data of the sensor and sends it to the access node. An access node can be connected to one ...
