A three-dimensional integrated buoy monitoring system capable of real-time beacon lights monitoring was developed to ensure the safety of inland waterway navigation.A buoy field unit monitoring the signal was linked with the remote command center via 3G wireless communication network, and combining with a computer software services platform, an organic integrated, real-time monitoring system regarding beacon lights was constituted on the remote control center monitoring platform, to ensure the normal operation stste of the beacon and the smooth passing of the waterway.The important parameters detected by the buoy field unit were transmitted to the monitoring center in real time, showing a clear site condition of the beacon.The system provides a strong guarantee for inland waterway traffic safety and also the cost saving for waterway maintenance.
