Problems solved by technology

However, the requirements for timeliness and reliability in industrial production are still very strict, so they cannot be directly applied to WirelessHART networks
[0005] To sum up, there is still no effective solution to the problem of how to integrate cluster routing and other methods into the WirelessHART network to achieve real-time and energy-efficient data communication when a large number of field devices are connected to the WirelessHART network in the prior art

Abstract

The invention relates to a data aggregation and routing method and communication architecture based on clusters in a Wireless HART network and is applicable to the real-time Wireless HART network. The method comprises the steps of in an uplink selection process of a Wireless HART communication protocol, selecting cluster heads of the clusters from network nodes according to the communication consumption, residual energy and data transmission frequencies of the network nodes; carrying out data aggregation on the whole network nodes according to the selected cluster heads, thereby forming a plurality of clusters, wherein the data transmission frequencies of the intra-cluster nodes of the clusters are smaller than those of the cluster head nodes; and finishing transmitting data through superframe scheduling according to the clusters. Compared with the most advanced Wireless HART communication protocol, the method and the communication architecture have the advantage that the service life of the network is improved by 40%, and the end-to-end delay constraint is satisfied.

Description

technical field [0001] The invention belongs to the technical field of real-time WirelessHART network communication, and in particular relates to a cluster-based data aggregation and routing method and a communication network applied in the real-time WirelessHART network. Background technique [0002] The WirelessHART communication protocol has been adopted by IEC (International ElectrotechnicalCommission, International Electrotechnical Commission) as the first open real-time wireless network communication protocol in the industrial automation control system. WirelessHART can meet the basic reliability, stability and security requirements of real-time wireless communication in the manufacturing industry. Compared with the fixed connection of tree network or star network, WirelessHART can use centralized control system to transmit data from different paths and redundant paths, which ensures the high robustness and fault tolerance of WirelessHART network. The network manager ...
