| With the progress of the intelligent and digital control systems, the field bustechnology has been a hot point in the international control system fields. At present,Internet plays more and more important poles in remote control system. The remotecontrol networks, which integrate field bus and Internet, become an importantscheme in remote control. In the remote control networks, field bus is used to realizethe control task, and Internet is used to realize the integration of control network andinformation network, and the user can realize remote control by Internet.The design and realization of remote control mode aims at the water resourcesmanagement information system in YunNan province, which integrates LonWorkscontrol network and Internet/Intranet, has been discussed in the paper. An elementaryscheme has been presented and the correlative methods have been realized. Firstly,the LonWorks technology and the structure and method of the remote control systembased on LonWorks have been analyzed. Secondly, the key technology of remotecontrol network has been discussed. Thirdly, based on the remote control technologyand LonWorks control networks, the actual scheme of remote control system basedon LonWorks, which apply to the water resources informations collection system,has been developed and realized. |
