Abstract: To solve the problem of data collection in heterogeneous devices with multiple protocols and large-scale clustered devices,as well as the problem of high availability of data collection for the high-value data,the highly available distributed data collection model based on an industrial message-oriented middleware was proposed.The Industrial data collection Message Queue (IdcMQ) was used as the carrier of the industrial message-oriented middleware in this method to define the architecture of IdcMQ and the running mode of the distributed cluster of IdcMQ for achieving high availability of data collection.According to the definition,the architecture composed of protocol adaptation,data processing and service providing,and the process of connecting and data collection of heterogeneous devices with multiple protocols was illustrated.The running mode composed of data synchronization rules,data synchronization level and data synchronization process,and the implementation principle of high availability of data collection was described.Based on the model,the industrial data collection message-oriented middleware software named IdcSentry was developed.The performance of IdcSentry was tested and two application cases were given to prove the effectiveness of the model.
