Beschreibung
Zusammenfassung:	The invention discloses an electrical control system based on optical cable transmission. The system comprises an on-site control box, a distribution cabinet and a DCS system. The on-site control box is connected with the distribution cabinet through an optical cable. The distribution cabinet is connected with the DCS system through an optical cable. The DCS system is connected with the on-site control box through an optical cable. A first microcontroller and a first photoelectric data conversion module which is connected with the first microcontroller and is provided with an optical cable interface are arranged in the on-site control box. A second microcontroller, a second photoelectric data conversion module which is connected with the second microcontroller and is provided with an optical cable interface, and a motor protector are arranged in the distribution cabinet. The optical cable interfaces are multimode optical fiber interfaces. Video monitor is arranged at the mounting position of the on-site control box. The video monitor data access a control room of the DCS system through an optical cable.
