Control System Based on Fieldbus for the Workshop of Unloading Coal Precipitator

The fieldbus technology is applied to the auto-control system of the coal unload workshop. The setting-up of the model, the design and the realization of the fieldbus control system are discussed. High-low voltage control systerm structure is analysed. Hardware of fieldbus and communication cards is designed. And the key points of the realization of the system are designated. The prospect of the fieldbus in controlling is also discussed. This technology can be well applied in practicality.
