| Abstract: |
| A controller for real-time data collection and network communication is developed for the coal feeder system of thermal power plant.Modbus /TCP protocol is used to realize the real-time data communication among different applications.It adopts the dual processors with parallel bus mode and task division construction.Data exchange between two processors is via 8-bit parallel data lines under the control of handshaking signal.The data are encapsulated according to Modbus /TCP protocol and the TTL signal is co... |
