Abstract
The invention relates to a large-scale thermal power generating unit EDPF-NT distributed control system. A large-scale thermal power generating unit needs to adapt to a wireless bidirectional communication control system for industrial environment control. The system comprises a controller, an interface work station, and a wireless communication module access EIO bus. An EDPF-COM is connected to the EIO bus through a local I/O and an IOBUS bus protocol converter. A remote I/O is connected to the EIO bus trough the IOBUS bus protocol converter. Onsite set equipment is connected to the EIO bus through an onsite bus protocol converter. A PLC controller and a serial port server are connected to the EIO bus. The controller or the interface work station is provided with an industrial Ethernet extension bus interface in an embedded manner, and cooperates with a wireless base station to jointly form a DCS wireless communication central control station, thereby achieving the wireless bidirectional communication with a plurality of distributed onsite stations at the same time. The onsite stations achieve the transmission of command, state and onsite information with the central control station through an arranged wireless transceiver.
