Research On The Key Technology Of The Reaction Kettle Monitoring System For Energy Conservation And Emissions Reduction Based On Internet Of Things

With the development of industrialization in China, the environmental pollutionis aggravating which has become a burning issue. The fact that the informationmanagement of industrialization lags behind and that interdisciplinary technologieslack collaboration, as well as the problem that the information platforms forinformation collecting, processing, sharing and appreciation are rare, influence themonitoring and management of the environment. Because of the low level of the dataacquisition technology, it is difficult to know about the main energy consumption andpollutants clearly and promptly during the waste disposal stage of industrial reactionkettle production process, which becomes a big problem of dealing with the industrialpollutants.Regarding industrial reaction kettle as the research object, the industrialprocesses of the biodiesel production and various monitoring parameters,characteristics and scopes of work of reaction kettle are analyzed combined with thecase of the biodiesel production on the basis of full investigations in this paper.What’s more, the IOT (Internet of Things) technology is applied in the reaction kettlemonitoring system in which the sensor technology is used for intelligent dataacquisition and the ZigBee wireless communication technology is used to make thedata transferred to host computer with high frequency signal. The development ofmiddleware realizes the communication between the host computer and applicationsystems which adopt SOA framework to reduce the coupling of the system.According to the systematic analysis, it is consisted of the data acquisition module,the data processing module and the data display module. Modules communicate witheach other through service mode which can truly realize the reactor productionenvironment monitoring and early warning and achieve the dynamic visual display ofmonitoring data. Faced with massive monitoring data, a set of data warehouse isestablished to unearth the potential useful information which can provide themanagement with the decision basis for the whole enterprise and the whole industryenvironmental monitoring.The domestic and overseas researches and applications of energy saving and emission reduction technology are analyzed thoroughly in this paper. On the baseabove, the research objectives, content and framework are put forward and the keytechnologies and applications of IOT in the monitoring system are researched.Intelligent data acquisition, wireless data communication, interface technology, datastorage, service-oriented architecture, data processing and visualization are exploredin this paper. In addition, the needs are analyzed and the service-oriented architectureis designed on the base of the reaction kettle. A set of practical index system isestablished according to the characteristics of collected parameters. By sampling testand exploration contrast, the system can achieve selection of effective sensor. As forthe ZigBee wireless transmission, a set of communication protocols are defined.Self-defining data communication can improve the flexibility of wireless transmission.Multithreading technology is used to regular polling access to monitor data. Thecache module is researched and developed independently to store the latest data.Besides, the SqlbulkCopy class is adopted to read data in batch and achieve thecommunication between the acquisition module and the data processing modulebased on WCF technology. WebService technology is adopted to realize thecommunication between the data processing module and the data displaying module.The results have been deployed and tested in practices and get good reputation fromusers.
