In order to overcome the shortcomings of VHF speech communication commonly used in current inland river traffic, we design an inland river shipping information automatic report system based on the key technologies of self-organized wireless data communication, GPS positioning, embedded software and hardware design, inland waters electronic chart, etc. The functions are implemented in the system laboratory prototype, which include automatic sensing to the surrounding ships, automatic alarming to dangerous ships surrounding too near, as well as automatic reporting information of shipping traffic to shore-based devices. The system have features of low realization and operation cost, automatic and accurate reporting shipping information, which improves the inland river traffic safety level.
