Abstract

The present invention relates to a smart jamming electronic grenade that is not exploded against our side. The grenade includes: a grenade body (10) filled with powder (11); a cap (12) provided on an upper end of the grenade body; an ignition output unit (300) provided in a lower end of an inner surface of the grenade body and spaced apart from an electronic detonator (200); a jamming device (20) spaced apart from the grenade body; and the electronic detonator provided to one end of the inner surface of the grenade body and having a switch (201), an IR signal receiver (202), and an IR signal transmitter (206) provided on a top surface thereof. If a microcomputer (240) of the electronic grenade is operated, operation of the device is initialized by a reset unit (241) provided in the microcomputer. A signal reading unit (242) determines whether the signal is an explosion signal or not. If the signal is the explosion signal, time for the explosion signal to reach an ignition output unit (300) is delayed by a delay circuit (243), and the explosion signal is sent to an output signal generating unit (244) after a predetermined time (3 to 5 seconds) set in the delay circuit has been passed. The explosion against our side is suppressed to prevent our army from being killed. Since our side cannot use the grenade against our side, various military actions can be conceived, and fighting spirit of our side can be raised.

Description

{Jamming hand grenade of Smart electronic}

More particularly, the present invention relates to an electronic grenade which is not detonated by a jamming signal in a friendly zone

Recently, various kinds of explosives have been operated by soldiers, and safety accidents are frequently occurring.

Therefore, in order to prevent accidents caused by acquiring allied explosives or being supplied to the private sector, it is necessary to use a technology that can only be used only in the military so as not to injure the public good, .

A method of detecting a weapon by emitting a specific signal is disclosed in Japanese Patent Application Laid-Open No. 2007-515628, which is based on an object detection method and a device. A method of directly hiding or jamming a weapon among friends If you use it, you may not be able to find the weapon in case you need it, making it difficult to attack or take action after the battle.

It is noted that the technology described in the above-mentioned document collects polarized waves reflected from a person or a facility after irradiating a person or facility entering the protected area with a power polarized wave.

It then measures the various parameters of the reflected signal and calculates their various selected differences to detect the hidden weapons, and their difference is to make the pattern plotted with the time function.

On the other hand, this method can be reversed to stop operation if the ally is within the identification range. This is achieved through a 'JAMMING system' which is also applicable to the above-mentioned technical literatures. In addition to the detection of the device, such jamming may also cause the device to give a different command to the conventional device, .

These technologies require electronic-based devices to control blasting, especially grenades.

On the other hand, a technology such as an electric ignition type tear gas disclosed in Korean Patent Laid-Open Publication No. 10-2005-0043185 has a warhead in which a tear gas is filled and an ignition tube is embedded in the rear of the warhead, Wherein the ward is formed with an annular outer ignition terminal provided at the rear of the ward, and an outer ignition terminal provided at the rear of the outer ignition terminal, wherein the ward is provided with an elastic member at the rear thereof, And a plurality of air discharge holes penetrating from the front side to the rear side are formed on the inner side of the inner ignition terminal, and the explosion which is ignited by electric or electronism is remodeled from the remote place by an IR signal or the like It is easy to use, and when it is equipped with sending / receiving function in this device, it is possible to easily operate from the enemy detection facility through jamming There are Jing.

At this time, it is preferable to designate the time designated arbitrarily in the delay circuit 243 as 3 seconds to 5 seconds, and the IR signal transmission unit 206 releases the input signal until the apparatus is demolished.

Therefore, when the signal reading unit 242 reads the jamming output signal transmitted to the IR signal receiving unit 202, the jamming output signal is transmitted to the interrupter 245, thereby stopping the operation of the apparatus.

When the output signal generator 244 transmits the explosion signal to the ignition output unit 300, the output signal generator 244 outputs the cable 205 provided at the lower end of the electronic primer apparatus 200, Is not transmitted unless it is connected to the terminal 301 provided at the upper end of the ignition output unit 300. In order to allow the output signal generation unit 244 to be replaced when the apparatus is misfired or defective, to be.

The output signal (explosion signal) generated by the output signal generation unit 244 is finally transmitted to the ignition output unit 300. When the cable 205 and the terminal 301 are coupled to each other, The ignition terminal 302 provided on one side surface of the grenade 300 ignites the gun powder 11 filled in the grenade 10 and causes the grenade 10 to explode.

The lower end of the step 203 is in close contact with the upper surface of the hand grenade 10 and the upper end of the cap 12 is in close contact with the upper surface of the grenade 10, Is mounted on the upper surface of the grenade so that the jointed state can be maintained.

If a device such as one or more units is supplied to the public, it may be harmful to good public order, so it must be supplied only for military purposes.

As described above, the content of the smart jamming electronic grenade is described concretely to limit the scope of the patent claim. The scope of the present invention is not limited to the technical scope of the present invention, To the extent that it can be derived.
