Description

Technical Field

[0001] The utility model relates to the field of shooting range tests, in particular to a controllable detonation device of a high-altitude balloon used for shooting range meteorological measurements. Background Art

[0002] High-altitude meteorological measurements at target ranges are a mandatory component of flight testing for artillery ammunition and long-range projectiles. High-altitude balloon measurements are primarily performed using high-altitude balloons, carrying sondes aloft to obtain atmospheric parameters such as temperature, wind speed, direction, and pressure. This provides crucial data support for weather forecasting and condition assessment during flight tests. High-altitude balloons can be categorized as either non-inflating or inflating types. Non-inflating balloons, with a sheath made of polyethylene or polyester film, have virtually no elasticity and maintain their shape. They are commonly used for horizontal surveying, such as in the construction of fixed-altitude and tethered balloons. Inflating balloons, with a sheath made of highly elastic rubber, expand freely as atmospheric pressure decreases until they burst. These balloons are generally used for vertical atmospheric surveying. High-altitude balloons are typically made of rubber or plastic and filled with lighter-than-air gases such as hydrogen and helium to facilitate launch. They offer advantages such as low investment, low cost, rapid results, long flight times, the ability to carry instruments for measurement, and high flexibility, making them the primary means of meteorological measurement at target ranges.

[0003] High-altitude balloons commonly used at shooting ranges are classified as small balloons. When inflated on the ground, they have a diameter of approximately two meters. As the air pressure decreases during ascent, the balloon slowly expands, reaching a maximum diameter of 8 to 11 meters. They have a maximum ceiling of 30,000 meters and can remain aloft for approximately two hours before exploding due to the internal and external pressure differential. These balloons are low-cost and flexible, but they carry a relatively small payload. They primarily carry basic meteorological measurement modules such as temperature, air pressure, and wind speed, lack a lift control system, and are not recovered after use. Meteorological departments also do not recover these balloons, allowing them to self-explode at a certain altitude. However, their release requires approval from airspace control authorities, a fixed location and time, and clear identification markings on the balloons. These measures minimize interference with air routes and other aircraft. Consequently, meteorological departments do not prioritize the control of these balloons, as demand for such control measures is low and no mature products are currently available.

[0004] Compared with the meteorological department, the frequency, time and location of balloon releases at the target range are variable, which causes great inconvenience to airspace declaration. The target range is required to take emergency measures for the high-altitude balloons used, and control the hovering time and flight altitude of the high-altitude balloons to prevent the high-altitude balloons from affecting flight routes and other aircraft. Summary of the Invention

[0005] The purpose of the utility model is to provide a controllable detonation device for a high-altitude balloon used for meteorological measurement at a shooting range, which can control the flight position and altitude of the high-altitude balloon by detonating it to avoid affecting the flight route or aircraft.

[0006] In order to achieve the above tasks, the present invention adopts the following technical solutions:

[0007] A controllable detonation device for a high-altitude balloon used for meteorological measurement at a shooting range comprises a ground signal sending device and a detonation device installed on the high-altitude balloon, wherein the high-altitude balloon carries a sounding instrument; wherein:

[0008] The ground signal transmission device is arranged in the ground station and includes a trigger and a wireless signal transmission antenna, wherein the trigger is used to issue a detonation command automatically or through an operator, and the wireless signal transmission antenna is used to send the detonation command to the detonation device carried by the high-altitude balloon;

[0009] The detonator includes a signal receiver, an ignition circuit and an ignition head, wherein the signal receiver is used to receive the detonation command sent by the ground signal sending device, and the ignition circuit is used to generate an ignition current according to the detonation command. The ignition current detonates the explosives in the ignition head to blast the high-altitude balloon.

[0010] Furthermore, the ground signal transmitting device further includes a power supply module, which is used to supply power to the trigger and the wireless signal transmitting antenna;

[0011] The detonating device further comprises a battery, which is used to supply power to a signal receiver and an ignition circuit.

[0012] Furthermore, the ignition head is pasted on the surface of the high-altitude balloon.

[0013] Furthermore, when the wireless signal transmitting antenna transmits the detonation command, the signal transmitting frequency is staggered by 400 MHz from the meteorological measurement data channel.

[0014] Furthermore, the trigger is connected to a signal acquisition device in a ground station; the signal acquisition device is used to receive the current height and position information of the high-altitude balloon obtained by the sounding instrument. When the height and position reach the preset detonation conditions, the trigger automatically generates the detonation command.

[0015] Furthermore, the preset detonation condition is: the current altitude of the high-altitude balloon reaches a preset altitude and the position is within a preset position.

[0016] Compared with the prior art, the present invention has the following technical features:

[0017] 1. The utility model provides an emergency measure for the safe use of high-altitude meteorological measurement balloons in shooting ranges, realizes the control of the high-altitude balloon's hovering time and flight altitude, and reduces the potential safety hazards caused by the high-altitude balloon to flight routes and other aircraft.

[0018] 2. The utility model increases the controllability of the high-altitude meteorological measurement balloon at the target range, is beneficial to airspace declaration, and improves the efficiency of flight test organization. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See attached Figure 1 The utility model provides a controllable detonation device for a high-altitude balloon used for meteorological measurement at a shooting range, comprising a ground signal transmitting device and a detonation device installed on the high-altitude balloon, wherein the high-altitude balloon carries a sounding instrument; wherein:

[0023] The ground signal sending device is arranged in the ground station and includes a trigger, a wireless signal transmitting antenna and a power module, wherein: the trigger is used to issue a detonation command automatically or through an operator; the wireless signal transmitting antenna is used to send the detonation command to the detonating device carried on the high-altitude balloon; the power module is used to supply power to the trigger and the wireless signal transmitting antenna.

[0024] The detonator is carried into the air by a high-altitude balloon and includes a signal receiver, an ignition circuit, an ignition head, and a battery. The signal receiver is used to receive the detonation command sent by the ground signal sending device; the ignition circuit is used to generate an ignition current according to the detonation command, and the ignition current detonates the explosives in the ignition head to blast the high-altitude balloon; the battery is used to power the signal receiver and the ignition circuit.

[0025] Optionally, the ignition head is attached to the surface of the high-altitude balloon; after the ignition head explodes the high-altitude balloon, it is damaged and loses buoyancy, thereby falling rapidly.

[0026] As a further optimization of the above technical solution, in this embodiment, when the wireless signal transmitting antenna transmits the detonation command, the signal transmission frequency is staggered by 400 MHz from the meteorological measurement data channel.

[0027] In a possible implementation of the present invention, the trigger is connected to a signal acquisition device in a ground station; the signal acquisition device is used to receive the current height and position information of the high-altitude balloon obtained by the sounding instrument. When the height and position reach the preset detonation conditions, the trigger automatically generates the detonation command.

[0028] Operators can also use manual control to determine the timing of issuing the detonation command based on information such as the height and position of the high-altitude balloon.

[0029] The preset detonation condition may be: the current altitude of the high-altitude balloon reaches a preset altitude and the position is within a preset position; in addition, the preset detonation condition may also be set according to actual needs.

[0030] Example:

[0031] In one embodiment of the present invention, the high-altitude balloon is a 790kg high-altitude balloon, the sonde is an XGP-3 sonde equipped with meteorological observation software; and a laptop computer for receiving sonde data is provided in the ground station.

[0032] The high-altitude balloon carries a sonde and is launched into the air to collect meteorological data. At the same time, it obtains the current position and altitude data of the high-altitude balloon, and sends this data to the ground station. After completing the meteorological data collection task, the operator decides to detonate the high-altitude balloon based on the current position and altitude of the high-altitude balloon. The operator presses the trigger switch, and the trigger generates a detonation command, which is sent to the detonator via the wireless signal transmission antenna, detonating the ignition head to explode the high-altitude balloon.
