A7 B7 PA870294.TWP-3 / 16 Printed by the Central Government of the Ministry of Economic Affairs, Coconut Consumer Cooperative, V. Description of the Invention (/) [Technical Field] The present invention relates to a Chinese international navigation warning telegraph system message receiver, especially It is a message receiver for receiving radio signals with frequencies of 518KHZ, 490KHZ and 4209.5KHZ. 5 [Previous technology] According to the current, Chinese fishermen can only receive English marine weather and exhausted information transmitted through international broadcasts. However, most fishermen cannot understand the English message. In order to serve the fishermen and protect their lives and property, It ’s safe. The Chinese solid-state voyage of the present invention is able to broadcast Chinese and English 10-language voyage information and provide important information for fishermen by printing it. Although it is used internationally in the past, 518KHZ frequency sends English messages. For the majority of fishermen, English messages are often unable to communicate. Therefore, the use of Chinese messages is an inevitable trend to improve the service level and quality. “Therefore, our company regulates the two channels 490KHZ and 4209.5KHZ for transmitting Chinese messages”, so that Chinese coastal fishermen can receive Chinese messages. The present invention can receive Chinese and English messages of the above three channels, and provide real-time maritime weather and emergency information for nautical operators' in order to translate the information of nautical operators to produce Wei turtles. If it is possible to inform the fishermen of the sea in an important inquiry in real time, it is possible to increase the fish catches of the fishermen in the sea to enhance the development of the fishing industry in China. Therefore, the practicability of the present invention and its contribution to the community can be seen. [Objective of the invention] The purpose of the present invention is to provide a Chinese international navigation warning telegraph system message receiver, which can provide fishermen's maritime safety, and the paper size of the maritime paper is applicable to China's national rubbing rate (CNS) A4 specification (210X297 mm )

Basically, the serial signal decoded by the RF receiver unit 6 conforms to the message format of Table 2 in addition to the CCIR code. That is, first send a synchronization signal for more than 10 seconds. This synchronization signal consists of consecutive 33H and 78H bytes, and then send 4 bytes of Chinese and English identification fields. When sending English, it is ZCZC. This is National standards for nakedness, or ZAZA identification for Chinese. The paper size is applicable to the Chinese Standard for Homelessness (CMS) A4 (210X297 male p A7 _____ — B7 PA870294.TWP-8 / 16 5. Description of the invention () After one box, send the transmitter's identification symbol and the transmission order indication level two. Then send the message serial number before sending the Chinese and English messages. Because the CCIR coding method can only send English letters and some numbers from A to Z. And special symbols. Therefore, the Chinese message of the present invention uses the Chinese internal code to be transmitted separately. 5 That is, the Chinese internal code has 4 digits and is a hexadecimal number. Therefore, transmitting 4 numbers represents a Chinese character. However, the Chinese internal code Changing the characters and numbers too frequently will increase the number of characters and numbers to control the number of bytes. Therefore, in the present invention, A ~ F still represents A ~ F in hexadecimal, and 0 ~ 9 in hexadecimal uses P ~ Y means so not But it can reduce the chance of transmitting the control code to reduce the sending time by 10, and it has the advantage of confidential communication.

Please refer to Figure 2 for the printed form of the consumer cooperative. In addition to the above-mentioned transmission method, the present invention also adopts a double f-material transmission method to increase the stability of reception. Because the present invention is a one-way transmission, so when an error is received When sending a message, it is impossible to send a signal to inform the transmitting end, so each byte is sent twice. When the two signals received are different, one of them must be wrong, and each byte has the characteristics of 4 to the right. , So it ’s easy to identify what was wrong and only keep it right Bytes. Of course, if the two bytes are detected, the error cannot be corrected, such as the D signal in the second, and the transmission method of the two is to delay the transmission of 4 bytes and then alternately transmit 'if the first received bit The tuple detects an error and replaces it with the correct byte from the second receipt. Therefore, the receiving controller unit 7 basically uses a microcomputer control to process the above complex signals, and then prints the received correctly < result from the thermal printer unit 8, the printer unit 8 uses a thermal printer ' It is mainly resistant to salt and moisture and will not lose important information because the result cannot be printed without a ribbon. The receiver data unit 9 is used to send the reception result to the transmitter to verify the correctness of the received message. The transmitter can control the receiving status of the receiver through this modem to achieve the purpose of monitoring. Finally, the alarm output unit 10 includes an alarm and an alarm light, which are used to notify the fishermen to check the reception result when the message is received. In addition, an alarm signal is generated to notify the fishermen for emergency treatment when the printer is out of paper or if there is any malfunction of the receiver. Please refer to Figure 3.
