Description

Wireless terminal for mortar automatic operation based on ad-hoc communication}

The present invention relates to an ad-hoc communication-based wireless terminal for automatic operation of a mortar, which not only commands and controls multiple mortars using a single unified wireless terminal for the automatic firing system of a mortar, but also uses ad-hoc-based wireless communication. This relates to a wireless terminal for automatic mortar operation that can overcome signal interference caused by mountainous terrain by establishing a network.

Figure 1 shows the basic structure of a conventional mortar. The mortar is composed of a gun barrel (1), an aiming port (2), a gun leg (3), and a gun tube (4), and is transmitted by wire or wireless from the front observation post. When a shooting request is received, the shooting specifications are calculated using a shooting specifications calculator at the shooting command center, and the gun barrel (1) is installed to point at the calculated impact point using the attitude measurement sensor (compass) based on the calculated information.

In addition, after dissipating the mortar using the horizontal beam handle, vertical beam handle, and horizontal adjustment handle of the gun leg (3), charge and fuse are adjusted according to the received shooting specifications, and the shell is manually released into the muzzle of the gun barrel (1). A shell is fired by charging it.

Meanwhile, the Defense Acquisition Program Administration is developing an improved mortar system and is currently deploying and operating a new digital-based, lightweight, automated mortar to the military.

In particular, 81 mm and 120 mm mortars are mounted on armored vehicles (APCs), dramatically increasing the power of the artillery by expanding the range of artillery shells and maximizing ease of movement compared to current mortars, and the automated fire control system allows for rapid and rapid fire. It is a weapon system capable of providing precise firepower support and is directly replacing the existing 4.2-inch self-propelled mortar.

Figure 2 is a diagram showing the launch system of a mortar currently in operation, and is divided into four operation modes: observation mode (10), command mode (20), shooting mode (30), and communication mode (40).

First, the observation mode (10) consists of observation equipment and observation data input/output devices that collect observation information by an observer, and the command mode (20) consists of a calculator and fire instructions that calculate shooting specifications using observation information acquired at the fire command post. and control is achieved, and in the shooting mode 30, it includes a digital sight that controls the mortar for firing the artillery. Lastly, in the communication mode 40, the devices can be connected to enable communication through transmission and reception of voice and data using wired or wireless communication methods.

However, this conventional mortar launch system is operated by individual equipment according to each operation mode, so there are problems with intercompatibility and operability between equipment, and in particular, a connection means for consistent wireless communication by distance and terrain is not provided. However, due to various wireless communication methods and differences in output, it is not possible to provide a means of stable and continuous communication connection.

For example, in the case of short-distance wireless communication, low-power, low-output wireless communication is possible, but in remote areas or mountainous terrain with severe signal interference, high-output wireless communication equipment is required, which may cause unexpected communication failures, delaying or making artillery fire impossible. there is.

In particular, in wartime conditions, long-distance wireless connections are impossible without the help of intermediate nodes such as base stations or relays, and due to the nature of mountainous terrain, there are frequent climate changes due to rocks, wind, and heavy rain, and unexpected wireless communication failures may occur due to high mountain peaks and video For large-capacity wireless communication such as transmission, a problem may arise that requires the construction of separate high-specification, high-output wireless communication equipment.

In addition, the conventional launch system requires a separate computer that can collect observation information, perform complex calculations, and display images, and because observers, commanders, and artillerymen use different equipment, there is no compatibility or launch system between the equipment. There are difficulties in expanding.

Patent Document 1 features a system that uses a camera mounted on an unmanned aerial system (UAV) to adjust the target while allowing the user to remotely check the area around the shell's impact in real time without communication failure. However, in the case of mortars used in small units, using an unmanned aerial system requires a lot of cost and time, making it unsuitable for use in actual combat.

In Non-Patent Document 1, as shown in Figure 2, laser and global positioning system (GPS) technology is used to automatically calculate and transmit shooting specifications, such as a digital scale, an observation data input/output device, and a shooting data calculator, to replace the existing manual method. It is characterized by automated input. However, because different equipment is used for observation mode, command mode, and shooting mode, problems arise in cost increase, scalability, and operation.
