Internetworking method for wireless intelligent meter reading system

Abstract

The invention discloses an internetworking method for a wireless intelligent meter reading system. The internetworking method is applicable to field of wireless intelligent meter reading and provides internetworking, namely communication support for the wireless intelligent meter reading system. The internetworking method totally comprises the following three steps: internetworking, communication and maintenance. In the internetworking stage, the internetworking method adopts a dual-address management algorithm (subnet address and entire network address), a concentrator maintains an entire network address mapping table, besides, the concentrator and a collector all maintain a subnet address mapping table, and accordingly, the storage space of a communication module of the collector is greatly saved. In the communication stage, the entire network address can be resolved as the route of a node, and the uplink and downlink data communication is realized through the operation on the entire network address. In the maintenance stage, the concentrator adopts the naming mechanism for the network nodes, the nodes in the network can be periodically inquired, and the network is enabled to be stable and reliable.

Description

technical field [0001] The invention belongs to the field of wireless intelligent meter reading, in particular to a dual address management algorithm in a tree topology collection network. Background technique [0002] At present, in my country, user metering instruments, namely electricity meters, water meters, gas meters, and heat meters, are generally installed indoors, and meter reading personnel go from house to house to collect data by manual meter reading. Due to the wide range of users and large quantity, this measurement method is very easy to cause errors. Manual meter reading is not only inefficient, but also not conducive to scientific management, which brings great difficulties to the modeling, analysis and planning of the urban management network. [0003] The research and application of meter reading automation was carried out in the 1990s, but due to the difficulties in the installation and maintenance of wired meters, the application of wired meter reading ...
