Embodiment Construction

[0032] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0033] The establishment of multi-hop routing is one of the key technologies for building wireless sensor networks. The wireless sensor network for the wireless meter reading system of the electric energy meter has the following characteristics: 1. The wireless meter reading system of the electric energy meter is composed of a concentrator and a collection terminal. The control command is sent to each collection terminal through the concentrator, and the electricity consumption data collected by the collection terminal It is transmitted to the concentrator in a multi-hop manner, that is, each collection terminal can be used as a router; 2. Both the concentrator and the collection terminal in the electric energy meter wireless meter reading system adopt the main power supply mode, so each collection terminal does not need to sleep 3. The concentrator nee...

Abstract

The invention relates to an autonomous networking method for a wireless meter-reading system of an electric energy meter. Each node in the system comprises a concentrator and a collection terminal. The method comprises the following steps: the node periodically transmits a neighbor switching command to a network in a broadcast mode; each node receives the neighbor switching command and add the node address transmitting the neighbor switching command into a self neighbor list; if the node can be in two-way communication with one node, and the node is added into a network, an uplink route from the node used as a father node to the concentrator is built; the node added into the network transmits a route updating command to the concentrator in a unicasting manner by a self father mode to build a downlink route from the concentrator to the node added in the network just now; the node added in the network just now is autonomously added into the network; the operation is performed in a circulating manner until all nodes are added into the network. The wireless meter-reading system utilizing the method has accelerated networking speed, is easy to maintain, can timely reflect the network state and realize an unmanned function thoroughly.

Description

technical field [0001] The invention belongs to the field of wireless sensor network communication, in particular to an autonomous networking method for a wireless meter reading system of electric energy meters. Background technique [0002] Wireless sensor network technology has been developed rapidly, and has a relatively high technical maturity in application. Using low-cost wireless sensor network technology to realize the wireless meter reading system of electric energy meter is the trend of technology development. Wireless sensor networks have the characteristics of low cost, robustness, flexibility and ease of use, and can be widely used in automatic meter reading systems for electric energy meters, industrial data acquisition and other occasions. [0003] The wireless sensor network ad hoc network technology is the key technology to build a wireless meter reading system for electric energy meters. At present, the automatic meter reading system of electric energy me...
