Sounding balloon with precise positioning

Abstract

The invention discloses a sounding balloon with precise positioning. The sounding balloon comprises an air bag filled with hydrogen and helium, a gas inflation and exhaustion component, a power compensation component and a controller. A GPS positioning module is integrated in the controller which is connected to the gas inflation and discharge component and the power compensation component. Compared with the prior art, the sounding balloon has the advantages that the disadvantages of the larger and larger pressure in a ball and easy burst in the lift-off process of the sounding balloon is overcome, in the recovery process of the sounding balloon, due to the gas discharge in the past, the buoyant force is reduced, added with the load of a meteorological data measuring device, the speed of decline is faster and faster, the balloon is in the danger of falling, the controller starts a motor according to the pressure signals fed by a built-in pressure sensor and an external pressure sensor, the motor drives a spiral wing to provides compensation power for the sounding balloon, and a crash is prevented. In addition, the sounding balloon can be precisely positioned by the GPS positioning module.

Description

technical field [0001] The invention belongs to the field of meteorological equipment and relates to a precisely positioned air-sounding balloon. Background technique [0002] High-altitude meteorological detection is to collect high-altitude meteorological data through the radiosonde carried by the sounding balloon, and the sounding balloon uses hydrogen or helium as the filling gas; [0003] Except for one meteorological station in Hong Kong (which imported the AUTOSONDE system from Finland's vaisala company), all the high-altitude meteorological detection side stations and the inflation of sounding balloons are manually operated. In the world, only a few developed countries such as Europe and the United States are equipped with unmanned high-altitude weather detection stations. So far, Finland is the only country that can develop an automatic balloon filling and deflation device for atmospheric detection. To realize unmanned high-altitude meteorological detection, the f...

AI Technical Summary

Problems solved by technology

[0005] Because in the atmospheric environment, especially at high altitudes, the air pressure and airflow are extremely unstable, and the gas pressure in the sounding balloon is also relatively high. In addition, after the sounding balloon itself is inflated, the wall of the airbag will be relatively thin. If the balloon During the continuous ascent, if the air pressure inside the balloon is not adjusted, it is easy to rupture due to excessive changes in air pressure, resulting in damage to valuable electronic equipment such as radiosondes, and even the situation that it cannot be recovered. At the same time, the sounding balloon is released. After reaching the sky, if the buoyancy of the sounding balloon is adjusted by adjusting the air pressure, the sounding balloon will keep rising. If it is not controlled, it is difficult to ensure that the balloon is at the best observation height. Not only will it cause the rupture of the sounding balloon, but also it is easy to lose the sounding balloon because of the high-air flow speed; Valve, to control the pressure of the balloon;

[0006] A recyclable sounding balloon is mentioned in ZL201220732719.0. Its recovery is mainly controlled by a thin rope to control its range of motion. Although the height of the sounding balloon can be well limited by the thin rope, it also greatly limits the detection capacity of the sounding balloon. The activity space of the air balloon, and the string itself is relatively easy to break or entangle, and it is easy to lose the sounding balloon and related electronic equipment;

[0007] ZL200920044465.1 proposes a set of automatic recovery, automatic inflation, and automatic emptying of the sounding balloon, although compared with the sounding balloon in the previous patent literature, it cancels the string component and enlarges the activity space of the sounding balloon At the same time, the air pressure of some balloons and the cooperation of guiding drive equipment and sensors have improved the control ability of the sounding balloon, but the mass of the electronic equipment itself is relatively large, which will bring a certain test to the load capacity of the sounding balloon. The temperature is relatively low, so it is difficult to guarantee whether these sensors can work normally. Once the sensor fails, it will still lead to the loss of control, loss or loss of the sounding balloon, which will bring a certain maintenance burden to the observation station

[0008] Most of the existing sounding balloons only consider that after rising to a certain height, the air pressure inside the ball is too high and needs to be deflated, but they do not consider that the air pressure inside the ball is too low when it is recovered, and it is easy to fall
