Problems solved by technology

If there is an abnormal situation such as a power outage in the entire station area, after the power supply is restored, it will take a long time for the central node and sub-nodes to complete the above-mentioned re-networking operations, and as the network capacity increases, the time spent will increase exponentially

Embodiment Construction

[0056] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] The electricity consumption information collection system adopts two-level network communication. The three communication nodes are the main station of the collection system, the concentrator, the collector or the electric energy meter from top to bottom. To remotely read the data of the collector or electric energy meter, the concentrator is equipped with a communication unit CAC, which is the central node of the micro-power wireless network, and the communication unit where the collector or electric energy meter is located is a sub-node; the first level of two-level network communication The network is a remote communication method between the main station and the concentrator of the collection system; the second level is the micro-power wireless communication method between the central node and the sub-nodes. In the network...

Abstract

The invention discloses a quick recovery method for a micro-power wireless network, and relates to the field of power utilization information collection. At present, when a whole region is in power failure or other abnormal situations occur, after a power supply is recovered, a central node and a sub-node need extremely long time to complete network rebuilding operation. The method comprises an overall region power failure recovery function process, a central node power failure recovery work process and a sub-node power failure recovery work process. According to the technical scheme, the nextstep of adjustment is performed after the central node and the sub-node are connected to the network, so that the stability of work is also improved while the power failure recovery is improved. During a network connection process, a part of steps are removed, and a plurality of tasks are simultaneously executed, so that the network is quickly recovered, and the losses caused by power failure arereduced.

Description

technical field [0001] The invention relates to the field of electricity consumption information collection, in particular to a method for quick restoration of a micropower wireless network. Background technique [0002] Under the power consumption information collection system of the power company, many on-site meter readings use micro-power wireless. The central node of the micro-power wireless is the micro-power wireless communication unit CAC integrated in the concentrator. The energy meter or collector of the communication unit. As the central node, the CAC unit will perform channel scanning after each power-on to determine the channel list for normal frequency hopping, and then perform a series of networking operations such as sending beacon frames, channel monitoring, and waiting for sub-nodes to apply for network access. After each child node is started, it needs to go through steps such as network discovery, parent node selection, and network access application ope...
