Abstract

The invention proposes an intelligent maritime radio telephone which includes a modem, a microprocessor, a TDMA transmitter, TDMA receivers, a radio receiver and an RX / TX switching switch. The TDMA transmitter and the TDMA receivers are all connected with the modem. The modem is also connected with the microprocessor. An output end of the TDMA transmitter is connected with the RX / TX switching switch. The RX / TX switching switch is also connected with the radio receiver. A first antenna is connected with input ends of the TDMA receivers. A second antenna is arranged on the RX / TX switching switch. The TDMA receivers are also used for polling and searching for free channels. The microprocessor is also used for tuning a communication channel of the radio receiver to the free channels searched by the TDMA receivers for conversation. The intelligent maritime radio telephone is capable of changing a single-communication state effectively, meeting navigation communication demands, guaranteeing conversation and thus enhancing navigation security.

Description

technical field [0001] This invention relates to communication equipment, and in particular to maritime radiotelephones. Background technique [0002] In the past 20 years, with the continuous improvement of communication and navigation technology, there are more and more ships sailing on the rivers. From the initial use of some simple communication and navigation equipment to now more and more high-tech communication and navigation equipment, the wide application of these equipment on board has greatly guaranteed the safety of ships and crews, and greatly reduced water traffic accidents. [0003] However, the most prominent contradiction caused by the increase in the number of ships is the pressure on ship communications. The almost unlimited increase in ships and the limited public communication channels are now increasingly becoming a pair of irreconcilable contradictions. Taking the Yangtze River waterway as an example, the particularity of the Yangtze River waterway. ...
