Research and Application of Dual Remote Redundancy Scheme for IGV Wireless Communication System of Automated ContainerTerminal
The communication methods commonly used in traditional docks,such as optical fiber and WiFi,have problems such as high construction and operation costs,poor stability,and relia-bility.In response to the high reliability requirements of the IGV(Intelligent Guided Vehicle)operation control network,a plan is proposed to adopt a 5.xGHz mobile wireless access system and configure dual remote redundancy.Through deployment testing at the Qinzhou Automated Container Terminal in Beibu Gulf Port,this plan has been verified to ensure that two links are connected to the central control room at the same time.When one link is interrupted due to ex-ternal factors,It can quickly switch to the backup link within 50ms,achieving stable and reliable wireless communication between the IGV and the central control room.
