Embodiment 1

[0016] figure 1 It is a schematic structural diagram of an airdrop positioning device provided in Embodiment 1 of the present invention. The airdrop positioning device includes: a motion state sensor, a GNSS positioning module, a communication module, a processor and a power supply module.

[0017] The airdrop positioning device provided in this embodiment is set in the airdrop device and is dropped simultaneously with the airdrop device.

[0018] The motion state sensor is used to obtain the motion state information of the airdrop positioning device. Motion state refers to the state of an object relative to a certain reference system when it is in mechanical motion, including static, uniform motion, accelerated motion, decelerated motion, and can also include linear motion and curved motion. The motion state sensor can also be called the attitude sensor, which is a high-performance three-dimensional motion attitude measurement system, including three-axis gyroscope, three-a...

Embodiment 2

[0028] On the basis of Embodiment 1, the processor is specifically used to encrypt the location information and periodically send the encrypted location information through the communication module when the motion state of the airdrop positioning device is static. After receiving the confirmation message of the latest location information, stop sending the encrypted location information through the communication module.

[0029] In order to increase the probability that the encrypted location information is received by the partner's search terminal, the encrypted location information can be sent periodically, but periodically sending the encrypted location information will increase the probability of being intercepted by the non-partner.

[0030] Therefore, in this embodiment, after the processor of the airdrop positioning device periodically sends the encrypted location information through the communication module, it may also stop passing the communication module after receiv...

Embodiment 3

[0036] figure 2 It is a schematic structural diagram of an airdrop positioning device provided by Embodiment 3 of the present invention.

[0037] On the basis of Embodiment 2, the motion state sensor included in the airdrop positioning device may be an acceleration sensor, and the acceleration sensor is used to obtain the motion acceleration of the airdrop positioning device; the processor is specifically used when the motion acceleration of the airdrop positioning device is 0 And after a preset time, the location information is encrypted and the encrypted location information is sent through the communication module. The acceleration sensor transmits the acceleration in each direction to the processor in real time. When the processor receives that the acceleration in each direction is 0 for a certain period of time, it judges that it is still, and the airdrop positioning device has landed and placed stably. Since the airdrop positioning device is affected by conditions such...

Abstract

The invention discloses air-drop positioning device, an air-drop positioning system and an air-drop device. The air-drop positioning device comprises a motion state sensor, a GNSS positioning module, a communication module, a processor and a power supply module. The motion state sensor is used for acquiring the motion state information of the air-drop positioning device; the GNSS positioning module is used for acquiring the position information through a GNSS; the processor is used for encrypting the position information and sending the encrypted position information through the communication module after determining that the motion state of the air-drop positioning device is static according to the motion state information; and the power supply module is used for supplying power to the motion state sensor, the GNSS positioning module, the communication module and the processor. According to the invention, when an air-dropped material falls off, the accurate position of the air-dropped material is reported to a search terminal, and a non-partner is prevented from acquiring the falling position information of the air-dropped material.

Description

technical field [0001] Embodiments of the present invention relate to positioning technology, and in particular to an airdrop positioning device and an airdrop positioning system. Background technique [0002] The airdrop device is a device that safely drops materials from an aircraft in the sky to the ground. The currently used airdrop devices are divided into two types: uncontrolled and positioning data correction. The uncontrolled airdrop device falls completely randomly after the airdrop. The airdropped materials and umbrellas are affected by factors such as wind force and wind direction, and the landing location may be far from the predetermined location. Positioning data correction devices rely on various means to try their best to control the airdrop device close to the predetermined location during the falling process, but it still cannot ensure that the landing position is at the predetermined location. [0003] In order to quickly and accurately obtain the materia...
