Problems solved by technology

Aiming at the problem that the complex building type of some communities cannot satisfy the collection of table information by a single collector, and a battery-powered auxiliary repeater is installed, it is necessary in a network environment with low frequency of topology changes and single-item data aggregation. Design a route establishment method that meets the design requirements of overall energy balance, and realize the horizontal and vertical data collection of the meters in the building by the collector and repeater

Embodiment Construction

[0047] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, the area to be collected is set to install a set of collectors and repeaters every three floors, and each node is connected to the background monitoring host through wireless networking. In practical applications, the collector repeater is generally installed in the collector of the electric meter and placed at the access control of the community building, and the common nodes are placed in the corridors and residents' homes according to the location of the meter.

[0049] Such as figure 2 and image 3 As shown, the specific steps of route establishment are as follows:

[0050] Carry out address coding and initial routing feature codes for each node, and set the period of the routing initiation interval and the listening limit time for the root node. The address code of a node consists of two parts: the...

Abstract

The invention discloses a method for establishing a clustered ad-hoc network routing for wireless centralized reading of three meters, and establishes a cluster model in which the power-powered collector and the battery-powered repeater are cluster heads to realize the gas meter in the building. networking. The method includes two processes of route establishment and route maintenance. The route establishment process is aimed at the actual situation that a battery-powered repeater needs to be installed to assist in collection based on the distance limit of the collector. A cluster-like model is designed and implemented in the "bucket" building, and energy balance classification is realized by considering node energy and link energy. During the route maintenance process, when there is a problem with the cluster head or auxiliary cluster head in the link, a node error message is sent out, and for the failed node, the most energy-saving method is used to re-network with the surrounding cluster heads to ensure reliable and efficient data transmission.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a method for establishing a clustered ad hoc network routing for wireless centralized reading of three meters (electricity meters, water meters, and gas meters). Background technique [0002] The wireless ad hoc network is a distributed wireless multi-hop network composed of a group of nodes with routing functions. Due to the limited transmission range of other nodes, other nodes are usually required to provide routing and relay functions when the source node sends data to the destination node. All nodes in the network and the wireless channels between nodes constitute the communication topology of the network. The topology changes brought about by the addition and deletion of nodes will cause changes in the communication forwarding path. Therefore, wireless ad hoc networks need to use dynamic routing algorithms to adapt to changes in topology and adjust routing. [0003] Ad...
