中文摘要 | 中文國際航行警告電傳播報系統( CNAVTEX )訊息接收機主要是用來接收中文國 際航行警告電傳播報系統所播報發射出來的中英文航海氣象及緊急資訊。本接收機可印出接 收到之訊息以便提供航海者航海氣象及緊急資訊。基本上本接收機採用微電腦控制整體接收 機之運作。由射頻接收機收到的信號轉換成數位信號後,送到微處理機,處理機收到信號後 轉換成字型字元送到印表機列印出訊息。另外為了與遠端發射系統能直接通訊,以便檢測接 收機之狀況,而另加 RS232C 介面以便外接數據機與發射系統連線。 |
英文摘要 | The CNAVTEX (Chinese National Alarm Voyage Telex) message receiver is used to receive both Chinese and English messages which include navigational and meteorological waring and urgent information broadcasted from CNAVTEX transmitter system. This receiver can print out the received messages in order to provide the messages for voyagers. Basically, the microprocessor is used to control the operations of the receiver. Firstly, the RF receiver converts the received messages into digital signal, and then the microprocessor will process the messages and convert them into the word pattern and print out the messages. The RS232C interface circuit is adopted in the receiver in order to connect to an additional MODEM for communicating with the remote transmitter side. |
