Abstract
With the progress of the intelligent and digital control systems, the field bus
technology has been a hot point in the international control system fields. At present,
plays more and more important poles in remote control system. The remote
works, which integrate field bus and , e an important
scheme in remote control. In the remote works, field bus is used to realize
the control task, and is used to realize the integration of work and
work, and the user can realize remote control by .
The design and realization of remote control mode aims at the water resources
management information system in YunNan province, which integrates LonWorks
work and /, has been discussed in the paper. An elementary
scheme has been presented and the correlative methods have been realized. Firstly,
the LonWorks technology and the structure and method of the remote control system
based on LonWorks have been analyzed. Secondly, the key technology of remote
work has been discussed. Thirdly, based on the remote control technology
and LonWorks works, the actual scheme of remote control system based
on LonWorks, which apply to the water resources informations collection system,
has been developed and realized.
