Design On Remote Monitoring Of Cement Rotary Kiln' Running State Based On Internet

With the development of science and technique,the importance of monitoring and controlling technology has being understood and recognized gradually overall the world industrial and agricultural fields.The combination of monitoring technology,computer technology and communication make Internet spreaded and developed rapidly in the field of measurement and control system.In the situation of equipment distributed widely and data acquisition difficultly,the remote monitoring and controlling technology is needed to monitor and control the operating state of equipment in time.The paper introduce clients monitor and control the remote measurement system through Internet.Firstly,developing trend of remote monitoring at home and abroad was introduced.I put forward the remote monitoring of cement rotary kiln combining the facts.the paper was divided into two parts,one part pay attention to the hardware designing about aquiring system,It analyzed how to chose the pattern of the hardware and function of every module principlly.I also gave the block diagram of the singlechip and host computer..the analog signals was upload to the singlechip which display and storage it,and then uploaded to the host computer through the RS485 bus,and then to the Ethernet.Secondly,In this paper,I introduced three mode:the TCP/IP,Datasocket and Remote panels baseed on LabVIEW.I studied and compared two kinds of structure,including B/S(Browse/Server) model,C/S(Client/Server)model,and sum up their respective advantages and disadvantages.C/S model have the simple,high effective characteristics.it had become one widespread platform of information exchange.but the B/S bases on the wide area network,It has strong adaption.the client oNIy have a general browser,so it greatly bring down the cost about exploiting and maintaining.in view of the LAN merit,so this paper raise the technique of Datasocket which base on C/S model.and realize the long-distance monitoring using the program and front panel methods.then realized the remote panels technique which base on B/S in brief.In the final analysis,the thesis use the LabVIEW as software exploitinig platform,the personal computer as the core control system about networking of virtual instruments.It combine the Internet networking communication technique and the LabVIEW virtual instruments technique to build remote monitoring system which monitor the offset of cement rotary kiln's main body.
