All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first", "second", "third", "fourth", and the like in the description and the claims of the present invention are used for distinguishing different objects, and are not used for describing a specific order. The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The existing Beidou satellite communication mode needs to carry out information transmission operation through a Beidou short message protocol, can know through reading a Beidou short message original protocol, different functions need different data frame headers, the data frame headers are not uniform and are irregular and difficult to remember, check codes are difficult to calculate, but the check codes are important data in Beidou communication, and special calculation tools or software are needed for assistance.
The sentence format of the existing Beidou short message follows the RDSS protocol, the RDSS protocol is a standard protocol issued by the Beidou central station, and the prior Beidou short message has a first-generation 4.0 protocol and a second-generation 2.1 protocol which have larger difference. The current common version is the second generation 2.1 protocol, which any R D module or chip supports. The most characteristic of the current 2.1 protocol is that the signal strength is represented by 10 wave velocities, and the previous 4.0 protocol is represented by 6 wave velocities. In this protocol, either a receiving statement or a sending statement, the statement starts with the dollar symbol, $, ends with english characters, and a separator, and ends with the carriage return line feed \ r \ n. The scheme of the embodiment of the invention is introduced and analyzed by the general second-generation 2.1 version protocol of the Beidou. The embodiment of the invention only introduces the more important and common protocols, and comprises the steps that a user uses a PC terminal to send data to an RD module (Beidou short message module) and the RD module sends feedback information after receiving the data.
Currently, the use of a reader card number:
the PC terminal is used for sending the statement to the RD module: $ CCICA,0,00 x 7B \ r \ n;
"CCICA" - - -reads the instruction key of the Beidou card number;
"0" - -monitoring local encryption and decryption module information;
"00" - -subordinate user information frame number;
"7B" - - -XOR check byte. Exclusive or operation is carried out on all bytes from $ to (excluding $ and) to obtain a check byte, then the check byte is converted into a 16-system number, and the upper 4 bits and the lower 4 bits of the 16-system number are taken. For example, if the check byte is converted into a 16-ary number and then is 0X07, then a 07 is written here and 0 cannot be omitted. The RD module replies to the PC terminal, such as:
$BDICI,0242286,00242286,0000011,6,60,3,N,0*38\r\n
"BDICI" - -instruction key.

"65" - -XOR check bytes.
The RD module replies to the PC terminal whether the command was successfully executed, for example:
$BDFKI,DWA,Y,Y,0,0060*0A\r\n

"1F" - -XOR check byte.
When the Beidou short message terminal is adopted to send and receive messages, a hybrid coding mode and a code coding mode are generally used. Taking the hybrid coding mode as an example, the first letter of the text is fixed as "a 4", and each character is converted into 16-system number capitals in sequence. If the 16-ary number is not greater than 16, 0 is complemented in the high order.
English is represented by one byte and chinese by two bytes.
For example, to send the information "hello beidou":
the PC terminal is used for sending the statement to the RD module:
$CCTXA,0242286,1,2,A468656C6C6FB1B1B6B7*7F
"CCTrxA" - - -instruction key.
"0242286" -recipient Address ID

"7F" - -XOR check byte.
Where a4 counts as a byte, which is the hybrid coded identification, which may be followed by 77 bytes of user content. 68656C6C6FB1B1B6B7 calculated 9 bytes, the user content is GBK coding, and the user can also adopt UNICODE coding, as long as UNICODE decoding is adopted at the receiving end.
If code encoding is adopted, A4 is removed, and the sending statement is as follows:
the code coding mode of $ CCTXA,0242286,1, 68656C6C6FB1B1B6B7 is also a mainstream application, and 78 bytes of user content can be transmitted. Since the mixed code needs a4 byte for marking, only 77 bytes of user content can be transmitted.
The RD module replies to the PC terminal whether the command was successfully executed, for example:
$BDFKI,TXA,Y,Y,0,0060*15\r\n；
"BDFKI" - - -instruction key.
"TXA" -keyword of a communication application;
"Y" - - -Y represents instruction execution success, and N represents instruction execution failure.
"Y" - - -Y represents that the frequency setting is successful, and N represents that the frequency setting is failed;
"0" - -emission suppression cue;
"0060" - -frequency wait time. Indicating how many seconds later it can be retransmitted again.
"15" - -xor check bytes.
If the set recipient address ID is self, the satellite will forward the information to the RD module within a few seconds, and then the RD module will output a statement to the PC terminal, such as: $ BDTXR,1,0242286,2, A468656C6C6FB1B1B6B7 x 46\ r \ n;
"BDTXR" -communication reply instruction.

If the sending end uses code encoding, the statement output after the receiving end receives is also in a code encoding format: $ BDTXR,1,0242286,1, 68656C6C6FB1B1B6B7 x 10\ r \ n;
when a user sends information by using the Beidou short message, the content can be English digits, Chinese characters or 16-system digits. At most 78 binary numbers/english/number, or 39 chinese characters can be transmitted.
The manner of obtaining the current time is as follows: the PC terminal is used for sending the statement to the RD module:
$CCRMO,ZDA,2,0*21\r\n；
where "CCRMO" - -instruction key.

As can be seen from the interpretation of the Beidou short message original protocol, different functions require different data frame headers, the data frame headers are not uniform, irregular and hard to remember, check codes are more difficult to calculate and are important data, and special calculation tools or software assistance is required for implementation. If one of the functions of the Beidou short message is required to be used, a corresponding instruction needs to be input into the RD module at the PC terminal, the instruction data is verified, and then the instruction data is sent together to realize the function. The aforesaid is that the current big dipper short message terminal of carrying on carries out the instruction mode of information interaction promptly, then can know by last, and the comparatively complicacy of current short message mode must just can accomplish through the training of specialty to the code mode is complicated relatively, and to equipment operator, the requirement is more, and the degree of difficulty is great.
