The Beidou airborne positioning terminal 101 provided by the embodiment of the invention not only improves the sending continuity of monitoring positioning data, but also provides alarm state information for the monitoring center 300 in an emergency state of an airplane.
Referring to fig. 2, an embodiment of the present invention further provides an aircraft positioning and automatic warning system 100, which includes the beidou airborne positioning terminal 101 in the foregoing embodiment, and further includes an airborne electronic display and control device 102.
The Beidou airborne positioning terminal 101 is the core of the whole airplane positioning and automatic warning system 100, and the outside of the Beidou airborne positioning terminal can be connected with the airborne electronic display and control equipment 102 through an RS-422 interface and is connected with the airborne data bus 400 through an ARINC429 interface.
Wherein, the onboard electronic display control device 102 is a main platform for the interaction between the pilot and the aircraft positioning and automatic warning system 100, and the onboard electronic display control device 102 includes: an electronic map module 1021 and a communication module 1022.
And an electronic map module 1021, which is configured to receive the positioning information of the airplane and load the positioning information onto the electronic map for displaying in a visual manner.

Optionally, the communication module 1022 generates the first communication and displays the second communication through a text input tool and a text communication interface.
The airborne positioning terminal 101 transmits the positioning information to the airborne electronic display and control equipment 102 through the first Beidou card module 1011 for displaying, and on one hand, the airborne electronic display and control equipment 102 utilizes the electronic map module 1021 to provide a backup positioning function for the pilot by reading the positioning data and displaying the positioning data on the electronic map; on the other hand, the communication module 1022 is also utilized to provide a text communication interface for the pilot to perform short message communication. The onboard positioning terminal 101 is also cross-linked with the onboard data bus 400 through the automatic alarm module 1013, so as to read the status information of the aircraft in real time, and the automatic alarm module 1013 monitors the alarm status information on the onboard data bus 400. When the automatic alarm module 1013 monitors that alarm state information exists on the onboard data bus 400, which indicates that an emergency alarm state occurs in the aircraft, the automatic alarm module 1013 sends a preset alarm message (i.e., a preset alarm message corresponding to the alarm state information) to the monitoring center 300 in the form of a beidou short message through the second beidou card module 1012 and the beidou satellite 200.
The airplane positioning and automatic warning system 100 in this embodiment includes the Beidou airborne positioning terminal 101 and the airborne electronic display and control device 102, and further includes a plurality of connecting lines. Which physically needs to be cross-linked with the on-board data bus 400. Mainly comprises the following functions: an emergency state automatic alarm function, a monitoring positioning function, a communication function and a backup positioning function.

The automatic alarm module 1013 in the beidou airborne positioning terminal 101 reads the aircraft status data from the airborne data bus 400 via the ARINC429 interface. The automatic alarm module 1013 stores preset alarm messages, and by monitoring the read aircraft state data, when alarm state information occurs, that is, when the aircraft is in an emergency state (for example, the pitch angle is too large, the oil amount is too low, and the engine fails), the preset alarm messages corresponding to the alarm state information are sent to the monitoring center 300 through the RDSS communication channel of the second beidou card module 1012, so that the automatic alarm function of the aircraft in the emergency state is realized.
The communication module 1022 in the multifunctional software in the on-board electronic display and control device 102 provides a text communication interface. The pilot inputs text information, namely first communication information, through the character communication interface, and after the text information is confirmed to be sent, the first communication information is transmitted to the RDSS communication channel of the second Beidou card module 1012 and is sent to the monitoring center 300 through the Beidou satellite 200; the monitoring center 300 sends the text information, i.e., the second communication information, to the RDSS communication channel of the second beidou card module 1012 through the beidou satellite 200, the second beidou card module 1012 analyzes and transmits the second communication information to the onboard electronic display and control device 102, and the onboard electronic display and control device 102 displays the second communication information on the text communication interface of the software, so that the communication function of the aircraft positioning and automatic alarm system 100 is realized.
The big dipper airborne positioning terminal 101 receives the signal of the big dipper satellite 200 through the RNSS positioning channel of the first big dipper card module 1011 and resolves the current position of the airplane to obtain the positioning information of the airplane, and then sends the positioning information (i.e. the second positioning information) to the airborne electronic display and control device 102. After the on-board electronic display control device 102 receives the positioning information, the positioning information is displayed in an electronic map by using an electronic map module 1021 in the multifunctional software, so that the backup positioning function of the aircraft positioning and automatic warning system 100 is realized.
