【摘要】：鋁電解行業(yè)一直屬于高耗能產(chǎn)業(yè),特別是近些年隨著電價不斷上漲,高昂的電費使得鋁電解企業(yè)承受的生存壓力越來越大。國內(nèi)外相關(guān)科技人員針對如何進一步解決節(jié)能降耗這個難點問題進行了大量的研究工作,并且逐步形成了統(tǒng)一認知,即通過陽極導(dǎo)桿電流分布監(jiān)測技術(shù),準確掌握整臺電解槽電流分布的實際情況,并作為判斷鋁電解槽實際工作狀態(tài)、降低槽電壓和預(yù)測陽極效應(yīng)的重要依據(jù),從而達到降低電能消耗,實現(xiàn)高效生產(chǎn)的目的。然而就目前實際情況來看,國內(nèi)鋁電解企業(yè)的電流分布監(jiān)測技術(shù)相比國外先進的鋁電解企業(yè)還有相當(dāng)大的差距。因此,設(shè)計鋁電解槽陽極電流分布在線監(jiān)測系統(tǒng)意義重大。 本課題采用TI公司的超低功耗單片機CC430F5137作為核心芯片,以開源的SimpliciTI作為網(wǎng)絡(luò)協(xié)議框架,提出包含現(xiàn)場采集節(jié)點、范圍擴展節(jié)點和數(shù)據(jù)處理節(jié)點的電流分布數(shù)據(jù)無線采集系統(tǒng)設(shè)計方案,并詳細闡述了單片機控制模塊設(shè)計、數(shù)據(jù)采集模塊設(shè)計和無線通信模塊設(shè)計過程,編制實際的通信協(xié)議,完成硬件系統(tǒng)的設(shè)計制作和網(wǎng)絡(luò)測試平臺搭建工作。 基于搭建的硬件平臺,分別進行AP、 RE和ED設(shè)備的程序設(shè)計,實現(xiàn)了現(xiàn)場采集設(shè)備、數(shù)據(jù)中心處理設(shè)備、上位機采集端的軟件設(shè)計,完成了網(wǎng)絡(luò)節(jié)點的加入退出、節(jié)點搜索、通信連接、跳頻、節(jié)點的休眠與喚醒、ED節(jié)點數(shù)據(jù)上傳模式切換等功能,確保數(shù)據(jù)采集與傳輸?shù)目煽啃�。使用Qt進行上位機采集端程序設(shè)計,實現(xiàn)了在網(wǎng)節(jié)點狀態(tài)顯示、采集節(jié)點數(shù)據(jù)讀取、節(jié)點配置下發(fā)等功能。 最后完成了整個系統(tǒng)的點對點通信、點對多點通信以及單個終端節(jié)點的通信性能測試,結(jié)果表明：各節(jié)點的通信性能良好,能夠準確采集數(shù)據(jù)并上傳至數(shù)據(jù)中心,實現(xiàn)了對鋁電解槽陽極導(dǎo)桿電流分布情況的實時監(jiān)測�；谝陨涎芯炕A(chǔ),設(shè)計了一套適用于鋁電解槽陽極電流分布的在線監(jiān)測系統(tǒng),并在某鋁廠400kA系列電解槽上完成了系統(tǒng)的性能測試,達到了預(yù)期效果。
[Abstract]:Aluminum electrolysis industry has always been a high-energy industry, especially in recent years, with the rising of electricity prices, The high electricity cost makes the survival pressure of aluminum electrolysis enterprises more and more heavy. Domestic and foreign scientists and technicians have done a lot of research on how to further solve the difficult problem of saving energy and reducing consumption, and have gradually formed a unified cognition. That is, through the current distribution monitoring technology of anode guide rod, the actual situation of the current distribution of the whole electrolytic cell is accurately grasped, which is an important basis for judging the actual working state of the aluminum reduction cell, reducing the cell voltage and predicting the anode effect. In order to reduce power consumption and achieve efficient production, however, the current distribution monitoring technology of domestic aluminum electrolysis enterprises is far from that of advanced aluminum electrolysis enterprises in foreign countries, in the light of the actual situation at present, the current distribution monitoring technology of domestic aluminum electrolysis enterprises is still quite different from that of foreign advanced aluminum electrolysis enterprises. It is of great significance to design an on-line monitoring system for anode current distribution in aluminum reduction cells. In this paper, the ultra-low power MCU CC430F5137 of TI Company is used as the core chip, and the open source SimpliciTI is used as the network protocol frame. The design scheme of current distribution data wireless acquisition system for extended node and data processing node is presented. The design of single chip microcomputer control module, data acquisition module and wireless communication module are described in detail, and the actual communication protocol is worked out. Finish the hardware system design and build the network test platform. Based on the hardware platform, the program design of APRE and Ed equipment is carried out, and the software design of field acquisition equipment, data center processing equipment and upper computer acquisition terminal is realized, and the network node is added and withdrawn, and the node search is completed. In order to ensure the reliability of data acquisition and transmission, the functions of communication connection, frequency hopping, node dormancy and wake-up Ed node data upload mode switching are ensured. Collection node data reading, node configuration sent down and other functions. Finally, the point-to-point communication, point-to-multipoint communication and the communication performance test of a single terminal node are completed. The results show that the communication performance of each node is good, and the data can be accurately collected and uploaded to the data center. The current distribution of anode guide rod in aluminum reduction cell is monitored in real time. Based on the above research basis, an on-line monitoring system for anode current distribution in aluminum reduction cell is designed. The performance test of the system has been completed in a 400kA series electrolytic cell of an aluminum factory, and the expected effect has been achieved.
