The embodiment of the invention provides a safety control and positioning recovery system for a high-altitude balloon, which is characterized in that an independent satellite communication link is arranged, so that information interaction with a ground satellite management station is realized, real-time acquisition of high-altitude balloon data information and uploading of command information are realized, control personnel on the ground can detect the flight state of the high-altitude balloon in real time and automatically control the cutting and separation of a sphere and a pod, and the position of the pod can be determined by returning pod positioning information in real time after the pod falls to the ground so as to recover the pod.

Fig. 5 is a flowchart of a high-altitude balloon safety control and positioning recovery method according to an embodiment of the present invention, and as shown in fig. 5, the high-altitude balloon safety control and positioning recovery method implemented based on the high-altitude balloon safety control and positioning recovery device includes,

step S1, the flying high-altitude balloon satellite information receiving and sending unit receives a cutting control instruction sent by a ground satellite management station and sends the cutting control instruction to a control unit;

step S2, after receiving the cutting control instruction, the control unit sends a cutting power supply instruction to the power supply unit;

step S3, the power supply unit supplies power to the cutting unit after receiving the cutting power supply instruction sent by the control unit;

step S4, the cutting unit finishes cutting the high balloon connecting rope after the power supply unit supplies power, and feeds back cutting information to the control unit;

step S5, after receiving the cutting information, the control unit receives the high-altitude balloon position information sent by the positioning information acquisition unit, and sends the cutting information and the high-altitude balloon position information to the satellite information receiving and sending unit;

and step S6, the satellite information receiving and sending unit feeds back the cutting information and the high-altitude balloon position information to a ground satellite management station.

Specifically, step S1, the control personnel on the ground determines that the ball and the pod of the high-altitude balloon need to be separated according to the position information transmitted by the high-altitude balloon in flight, sends a cutting control instruction to the high altitude in flight through the ground satellite management station, and sends the cutting control instruction to the control unit after the high-altitude balloon in flight satellite information receiving and sending unit receives the cutting control instruction sent by the ground satellite management station;

step S2, the control unit sends a cutting power supply instruction to the power supply unit after receiving the cutting control instruction sent by the satellite information receiving and sending unit;

step S3, the power supply unit supplies power to the cutting unit after receiving the cutting power supply instruction sent by the control unit;

step S4, the cutting unit finishes cutting the high-altitude balloon connecting rope after the power supply unit supplies power, separation of the high-altitude balloon and the pod is realized, and cutting information is fed back to the control unit and is used for feeding back to the ground satellite management station, so that control personnel on the ground can detect the flight state of the high-altitude balloon;

step S5, the positioning information acquisition unit acquires the high-altitude balloon position information in real time and sends the high-altitude balloon position information to the control unit, and after the control unit receives the cutting information, the control unit sends the high-altitude balloon position information and the cutting information sent by the positioning information acquisition unit to the satellite information receiving and sending unit;

and step S6, the satellite information receiving and sending unit feeds the cutting information and the high-altitude balloon position information back to a ground satellite management station, and a control person on the ground obtains the cutting information fed back after cutting the high-altitude balloon connecting rope and the current high-altitude balloon position information through the ground satellite management station.

The high-altitude balloon safety control and positioning recovery method implemented based on the high-altitude balloon safety control and positioning recovery device provided by the embodiment of the invention is implemented by using the high-altitude balloon safety control and positioning recovery device, and the specific implementation mode is consistent with that of the device, and is not described herein again.

The embodiment of the invention provides a safety control and positioning recovery method for a high-altitude balloon, which is characterized in that an independent satellite communication link is arranged to realize information interaction with a ground satellite management station and realize real-time acquisition of high-altitude balloon data information and uploading of command information, control personnel on the ground can detect the flight state of the high-altitude balloon in real time and automatically control the cutting and separation of a sphere and a pod, and the pod can be returned in real time to determine the position of the pod according to pod positioning information after the pod falls to the ground so as to recover the pod.
