Description
Technical Field
The invention relates to the field of satellite communication, in particular to a reliable information transmission method of a Beidou terminal all-in-one machine.
Background
The Beidou satellite independently researched and developed in China successfully transmits continuously, has unique short message communication service and can realize a data transmission function, has the characteristics of wide coverage range, no communication blind area, no limitation of surrounding infrastructure, good information encryption transmission safety and the like, and along with the construction of a Beidou third satellite navigation system, the short message regional communication capacity is expanded to 14000 bits (1000 Chinese characters) each time, and supports 560 bits (40 Chinese characters) of global communication capacity each time, so that the Beidou third satellite navigation system is widely applied to the fields of traffic transportation, marine fishery, hydrological monitoring, weather forecast, mapping geographic information, forest fire prevention, communication time system, power scheduling, disaster relief, emergency search and rescue and the like, and gradually permeates the aspects of human social production and people life.
However, the strength of the Beidou signal is greatly influenced by the environment, the Beidou antenna can acquire the Beidou satellite signal only in the open without shielding objects and under the condition that the direction of the antenna faces south, and the Beidou signal is interfered by severe weather, clutter, buildings and the like, so that the receiving and sending success rate of the Beidou short message is reduced. The Beidou satellite has no information feedback mechanism for the short message, and after the Beidou equipment sends the short message, whether the short message is sent successfully or not cannot be judged through the satellite, so that information is easily lost under the condition that the strength of the Beidou signal is low. Because there is a speed limit in the sending of the big dipper short message, the sending interval of every two short messages cannot be less than 60 seconds, so when a plurality of short message information needs to be sent, the information is lost due to untimely sending.
Disclosure of Invention
In order to overcome the defects and shortcomings in the background technology, the invention provides a reliable information transmission method of a Beidou terminal all-in-one machine. The method can effectively reduce the problem of information loss caused by low Beidou signal intensity.
In the aspect of software, the invention is provided with a Linux operating system and a MySQL database (the type of the database can be changed according to requirements), and is provided with a WEB middleware program which is independently developed by people, so that a user can directly connect a computer through a network cable or log in a WEB interface of equipment through a local area network for operation.
Install power management module, control module and a big dipper module in the casing of this equipment in the aspect of the hardware, big dipper module is connected to on the control module circuit board. When the Beidou card is used, a user needs to install the Beidou card and is externally connected with a Beidou antenna. The Beidou module is used for receiving short message information sent by Beidou equipment, the control module stores the sent short message information into a sent list of the database, stores the received short message information into a receiving list of the database, and stores short message information waiting to be sent into a list to be sent.
The content of the short message to be sent and the number of the receiver are filled in the WEB middleware, the database can be directly operated to add the short message and the number of the receiver, when the control module detects that the information to be sent exists in a list to be sent, the control module can automatically send the short message to a Beidou satellite through the Beidou module, and each short message is continuously and repeatedly sent for five times, so that the sending success rate of the short message is ensured.
Drawings
FIG. 1 is a functional diagram of the present invention.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in the figure, firstly, a WEB middleware interface is logged in a computer, a sending time interval of a short message is set in a system setting menu bar, the sending interval is set to be more than 60 seconds due to the frequency limit of the Beidou short message, then, the sending menu bar is opened, the content of the short message to be sent is added, the Beidou card number for receiving the short message is filled in a receiving target, the content of the short message and the receiving number can be automatically stored in a list to be sent in a database, and the short message and the receiving number can also be directly added in the database.
When the WEB middleware detects that the content exists in a to-be-sent list of the database, each short message is automatically recoded, a 4-byte unique ID number is added at the beginning, then an instruction is sent to the Beidou module, the short message is sent to the Beidou satellite and then sent to the Beidou equipment of a receiver, each short message can be automatically and repeatedly sent five times, the sending time interval of each time is determined by the time in the system setting, the sending success rate of the short message can be ensured by the repeated five-time sending, and the problem that the information is lost due to the fact that the Beidou signal is not good is solved.
When detecting that a plurality of short messages wait to be sent in a list to be sent, the system can sort the short messages according to the order of submission and send the short messages in sequence, so that short messages which are not sent in time are not lost due to frequency limitation, and the reliability of Beidou short message information transmission is improved. After the short message is repeatedly sent for five times, the WEB middleware stores the content, sending time, receiving number and other information of the short message into a sent list of the database, so that the subsequent check is facilitated.
The Beidou terminal all-in-one machine of the receiver receives the short message, firstly obtains the ID number of the short message code, then compares the ID number with the ID number in the database receiving list, discards the short message if the ID number is the same, and stores the received short message in a warehouse if the ID number is not the same in the database receiving list, so that the receiving of repeated short messages, the content of the received short message, the number of the sender, the receiving time and other information are prevented from being stored in the receiving list of the database, and the follow-up viewing is facilitated.
