Abstract

The invention provides a backbone routing device in line with an ISA100.11a standard and a routing method. The backbone routing device comprises a radio transmission module and a routing module, wherein the radio transmission module is used for completing transceiving of wireless frames, performing communication with the routing module and realizing communication with a terminal device of a DL sub-network; the routing module is used for performing transmission of data packets through a network interface module, a gateway device, a system manager and other backbone routing devices, and realizing backbone routing of the terminal device of the DL sub-network and packaging and parsing of IPv6 data packets. The backbone routing device provided by the invention can realize the advantages of a backbone network in the standard to the greatest extent, further bring out the advantages of high easiness in network expansion, high transmission efficiency of the terminal device and the like, and better realize the application of a wireless sensing network system in an industrial field.

Description

technical field [0001] The invention relates to a backbone network routing device and a backbone routing method conforming to the ISA100.11a standard, and belongs to the technical field of industrial wireless sensor networks. Background technique [0002] ISA100.11a standard, as one of the three major standards of industrial wireless sensor network, is changing the industrial field application. The ISA100.11a standard supports various network topologies, such as star network topology and Mesh network topology. The star network topology is easy to implement and has high real-time performance, but it is limited to a single-hop range. Although the Mesh network topology can improve the reliability of communication between terminal devices, the devices require more complex routing protocol support, consume more hardware and software resources, and increase data transmission delays, which is the most deadly sensor network. defect. In order to expand the network coverage without...
