Device used for carrying lightweight remote sensing sensor and provided with power helium balloon

Abstract

The invention discloses a device used for carrying a lightweight remote sensing sensor and provided with a power helium balloon. The device is mainly used for carrying the lightweight remote sensing sensor to carry out a ground surface remote sensing monitoring task. The device comprises a flight module (1), a communication and control module (2), a first battery (3), a pan-tilt holder (4) and a ground control module (5). According to the device, the ground control module is adopted to control a line winding motor to release and control the device; since the helium balloon is adopted, on the one hand, buoyancy can be provided, and safety can be increased; since universal rotor wings are adopted, the direction of the device can be flexibly changed, and the device can have better maneuverability; a user does not need to worry about the missing of the device through collecting a control line; and a rotor wing unmanned aerial vehicle requires an opener airspace when taking off or landing, and however, the helium balloon and rotor wing protective screen of the device can protect the rotor wings, so that requirements for take-off and landing airspaces are lower, and therefore, the device can take off and land in woods and complex terrains.

Description

technical field [0001] The invention relates to a light weight remote sensing sensor carrying device based on a powered helium balloon, which is mainly used for carrying the light weight remote sensing sensor to carry out surface remote sensing monitoring tasks. Background technique [0002] As an important technical means of surface monitoring, remote sensing monitoring is mainly realized by carrying corresponding remote sensing sensors on a certain platform, such as artificial satellites, airplanes, unmanned aerial vehicles or balloons, to carry out remote sensing monitoring tasks. The sensors carried by satellites, that is, satellite remote sensing, are generally used for large-scale monitoring tasks. The disadvantage is that they are affected by clouds or terrain, and monitoring data cannot be obtained in covered areas; the sensors carried by aircraft, namely aerospace remote sensing, can also be used for large-scale areas. , the disadvantage is that the flight route nee...

Problems solved by technology

The sensors carried by satellites, that is, satellite remote sensing, are generally used for large-scale monitoring tasks. The disadvantage is that they are affected by clouds or terrain, and monitoring data cannot be obtained in covered areas; the sensors carried by aircraft, namely aerospace remote sensing, can also be used for large-scale areas. , the disadvantage is that the flight route needs to be customized in advance and apply for airspace, and the flight is also affected by the weather; UAV remote sensing is used for monitoring tasks in a small area, the disadvantage is that the take-off and landing of the UAV needs to be relatively flat and open ground, otherwise it will increase the risk of UAV crashing and equipment damage during take-off and landing. At the same time, under the condition of weak positioning signal in mountainous areas, UAVs are prone to lose contact; remote sensing balloons can be suitable for For remote sensing monitoring tasks with large and small areas, the problem is that if it is a hot air balloon, it needs to carry fuel, which has certain risks, and a large space is required for take-off and landing. General helium balloons or hydrogen balloons are very convenient for take-off and landing, but due to lack of power , it is difficult to adjust the attitude in the air, and the quality of monitoring and imaging data will be affected by the effect of wind, and hydrogen is a flammable and explosive gas, which has potential safety hazards

[0003] Among the existing inventions, the invention application number CN201521053595.3 provides a hovering and attitude control system for taking pictures of fruit trees. The system uses a nitrogen balloon to hover, and the buoyancy generated is not as large as the helium balloon used in this device. In addition, , the device lacks a satellite positioning signal receiver, therefore, it is impossible to know the sampling position, and it is still lacking for fixed-point accurate sampling work
