Description

Technology Field

[0001] The present invention relates to a GPS cargo reserve parachute deployment device using a transceiver equipped with a GPS function, and more specifically, to a device that deploys a GPS cargo reserve parachute by operating a cutter through a voltage amplifier, using a transceiver equipped with a GPS function, in preparation for the case where the main parachute for the GPS cargo fails to deploy. Background Technology

[0002] A parachute is a device that uses air resistance to reduce the speed of descent when an object falls through the air, and it is primarily used for dropping objects from aircraft or for rescue operations. Generally, a parachute system consists of a main parachute and a reserve parachute; it is designed so that if the main parachute fails to function properly, the reserve parachute deploys to ensure a stable descent.

[0003] The primary parachute may malfunction due to various causes (e.g., line kinking, material defects, improper placement, etc.). In such cases, logistical efficiency decreases due to cargo damage or deviation from the target point, and in some instances, serious economic losses may occur. To prevent this, a backup parachute is included. In other words, the backup parachute is an essential component for preventing these risks.

[0004] An automatic deployment device is also used as a type of the aforementioned reserve parachute. An automatic deployment device is a mechanism that automatically deploys the parachute based on an altimeter, timer, and other indicators. It is designed to activate when the falling object reaches pre-set conditions (e.g., a specific altitude or speed) and operates without direct human intervention.

[0005] However, the following problems may occur during descent due to various environments and unexpected situations. Altimeters or velocity sensors may malfunction, or incorrect data may be collected due to environmental factors (e.g., electromagnetic interference). Additionally, if the set conditions do not match the actual descent conditions, the deployment timing may be too early or too late, or deployment may not be performed normally before final landing.

[0006] To solve the above problems, reference can be made to the prior art Remote parachute activation device (US 5398891). The aforementioned document provides a device that remotely deploys the parachute of another skydiver by one skydiver during an aerial descent. The above technology has the effect of deploying the parachute through remote control of skydivers falling simultaneously, through a configuration including an electronic transceiver, a transceiver storage box, and a trigger means. However, this is a system utilized when a person is falling and transmission and reception occur over relatively short distances and at similar altitudes, and it describes only an adjustable electronic valve and a transistor as an example of the trigger means. Therefore, it has the disadvantage that it cannot be used for transmission and reception over long distances or differences in altitude, and not only does it cause problems in determining the real-time location of the falling target, but it also cannot be used for cargo.

[0007] In order to solve the aforementioned problems, the need for a specific and concrete development of a remote cargo reserve parachute deployment device was deeply recognized through an analysis of the fact that a remote transmission and reception system with the ground is required because a person does not fall with the cargo parachute, the need to accurately identify the landing point of the cargo, and the fact that the aforementioned prior art remote parachute activation device does not provide specific means or principles for a micro-puller. Consequently, the present invention was completed. The problem to be solved

[0008] The present invention aims to solve the problem of providing a device capable of determining the real-time location of a cargo from the time the GPS cargo reserve parachute is deployed until the cargo is directly recovered, by having a GPS-equipped transceiver amplify a signal received from a ground-based transceiver using a voltage amplifier to operate a cutter and deploy a GPS cargo reserve parachute in preparation for the case where the main parachute for the GPS cargo fails to deploy, and by having a device capable of determining the real-time location of the cargo from the time the GPS cargo reserve parachute is deployed until the cargo is directly recovered. means of solving the problem

[0009] In order to solve the above-mentioned problem, the present invention

[0010] A GPS cargo reserve parachute deployment device is provided as a means of solving the problem, characterized by comprising: a transceiver equipped with a GPS function; a voltage amplifier; a cutter that stores explosives internally and has a function to push out a blade as the explosives explode when voltage is applied; and a protective case with air holes formed on the side of the case.

[0011] In order to solve the above-mentioned problem more effectively,

[0012] The above-mentioned transceiver equipped with the GPS function may be a transceiver capable of communicating with each other up to a maximum line of sight distance of 10 km, and the above-mentioned voltage amplifier may be a voltage amplifier that amplifies a given voltage to 80 V or higher.

[0013] The above transceiver includes a GPS module, and the above protective case includes a cushioning material. The cushioning material may be made of polyethylene foam (PE foam), polyurethane foam (PU foam), expanded polystyrene (EPS, Styrofoam), expanded polypropylene (EPP), corrugated cardboard, bubble wrap, air cushion, etc. Effects of the invention

[0014] The present invention has the effect of safely and accurately deploying a GPS cargo reserve parachute within the maximum line of sight using a transceiver equipped with a GPS function to prepare for cargo falling in an unintended location due to a failure of the GPS cargo main parachute or automatic deployment device.

[0015] Furthermore, the cargo can be tracked in real time thanks to a transceiver equipped with GPS functionality. Unlike parachutes used for human descent, cargo parachutes are heavily influenced by cargo weight and weather conditions, necessitating real-time location tracking. In particular, military supplies must be recovered before their location is detected by the enemy. For human parachutes, rescue may be deemed impossible or difficult depending on the landing site or terrain, and the individual may have already died before a rescue team is dispatched. In such cases, the need for rapid recovery is not significant. However, for high-value materials at high risk of breakage or damage, rapid recovery is essential for efficient combat operations.

[0016] In addition, the present invention has the effect of rapidly and accurately opening and dispersing a reserve parachute by remotely transmitting from the ground to detonate a small amount of explosive inside the cutter and advancing the cutter.

[0017] In addition, by installing the transmitter and receiver inside a protective case with air holes formed on the side of the case, damage to the transmitter and receiver is minimized when the cargo comes into contact with the ground, taking into account the weight of the cargo.

[0018] The GPS cargo reserve parachute deployment device of the present invention, having such effects, can be used in various situations, such as when air-dropping food, ammunition, medicine, etc., loaded onto cargo in combat zones or hard-to-reach areas; when air-dropping emergency supplies loaded onto cargo in island areas or areas with blocked transportation; when dropping emergency supplies from large transport aircraft; and when air-dropping food, water, medical supplies, etc., loaded onto cargo in earthquake, flood, or war zones.

[0037] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 shows the overall structure of a GPS cargo reserve parachute deployment device. As shown in Figure 1, a protective case equipped with a GPS transceiver installed on the side of the cargo and a GPS cargo reserve parachute are located side by side.

[0039] The aforementioned transceiver performs the function of remotely transmitting signals from the ground or receiving said signals during descent to generate vibrations, and plays the role of calculating and transmitting real-time positions. The aforementioned protective case is essential to prevent the transceiver from being destroyed by the weight of the cargo or the descent environment when the cargo touches the ground. Additionally, as previously mentioned, the aforementioned spare parachute serves to ensure the cargo lands normally on the ground in preparation for the failure of the main parachute.

[0040] FIG. 2 shows a transceiver equipped with a GPS function and the interior of a protective case in which the transceiver is installed. The transceiver may preferably be a radio. The transceiver includes a transceiver installed inside the protective case that falls from the air along with the cargo (hereinafter referred to as the "falling transceiver") and a transceiver controlled by a person on the ground (hereinafter referred to as the "grounding transceiver"). When the cargo falls, if the main parachute is not deployed and the distance between the transceivers is within the allowed mutual communication range, a signal is transmitted to the falling transceiver via the grounding transceiver. The falling transceiver can calculate its current location by receiving satellite signals through a GPS module and transmits the location to the grounding transceiver. Therefore, the real-time location of the cargo in which the falling transceiver is installed can be determined through the grounding transceiver.

[0041] The interior of the protective case is filled with cushioning material to protect the drop transmitter / receiver from external impact and prevent shaking. The cushioning material may consist of polyethylene foam (PE foam), polyurethane foam (PU foam), expanded polystyrene (EPS, Styrofoam), expanded polypropylene (EPP), corrugated cardboard, bubble wrap, air cushion, etc. Air holes are formed on the sides of the protective case to maintain internal pressure balance during airborne drop, thereby preventing the protective case from rupturing or deforming. Additionally, as air escapes through the air holes, the protective case can partially absorb the impact generated when it touches the ground, thus preventing damage to the drop transmitter / receiver.

[0042] FIG. 3 shows a voltage amplifier, which can be connected to the bottom of the drop transmitter / receiver as shown in FIG. 2. When the cargo is falling and the main parachute is not deployed, a signal is transmitted from the ground transmitter / receiver to the drop transmitter / receiver within the allowed mutual communication distance between the transmitters / receivers. The drop transmitter / receiver generates vibration and voltage through the received signal. The voltage generated at this time is amplified through the voltage amplifier to a voltage sufficient to operate the cutter.

[0043] A GPS cargo reserve parachute deployment device according to one embodiment of the present invention may include a transceiver equipped with a GPS function having a mutual communication distance of up to 10 km of line of sight, a voltage amplifier that amplifies a given voltage to 80 V or higher, and a cutter that operates when a voltage of 80 V or higher is applied.

[0044] Figure 4 shows a spare parachute and cutter for GPS cargo.

[0045] Figure 5 shows a plan view of a cutter.

[0046] Figure 6 shows the GPS cargo reserve parachute deployed.

[0047] As shown in FIG. 4, the GPS cargo reserve parachute is secured by a closing loop, and as shown in FIG. 5, the cutter is secured by passing the closing loop through a hole located at the end of the cutter (e.g., the left end of the cutter). The voltage amplifier shown in FIG. 3 is connected to the other end of the cutter (e.g., the right end of the cutter). Explosives and a blade are present inside the cutter. Upon receiving voltage from the voltage amplifier, the cutter detonates the explosives present inside the cutter, advancing the blade of the cutter into the hole located at the end of the cutter. The blade of the cutter cuts the closing loop of the GPS cargo reserve parachute and disperses the GPS cargo reserve parachute as shown in FIG. 6.

[0048] After the cargo lands on the ground, the location of the cargo where the drop transmitter / receiver is installed can be identified through the ground transmitter / receiver, allowing the cargo to be located quickly and accurately.

[0049] Due to the configuration described above, the GPS cargo reserve parachute deployment device of the present invention can solve the problems of main parachute failure and deployment delay (or early deployment) of the automatic deployment device. Explanation of the symbols
