Description

[0001] WIDEBAND JAMING DEVICE ON BOARD VEHICLE [0002]

The present invention relates to an in-vehicle type broadband radio disturbing apparatus, and it is an object of the present invention to provide a radio disturbing apparatus mounted on a vehicle using a battery to supply power to the apparatus, Mounted type broadband radio disturbing device in which the weight of the device is reduced due to the simplified components, and the efficiency of the device is improved by facilitating handling and utilizing cool air from the air conditioner of the vehicle to heat the device.

In a rapidly changing wireless communication market, explosives are remotely controlled by using mobile phones or wireless devices to explode, or there is a frequent occurrence of doubtful conversations. Therefore, there has been a demand for radio disturbance, that is, jamming, in order to protect VIPs from remote explosives and / or interception, and to protect the safety of the people who send overseas.

In addition, terrorist attacks on major facilities of unmanned airplanes and the threat of attack by self-exploitation or high-explosive explosion far exceed common sense levels, threatening the security environment at home and abroad at a very high level globally, Threats are steadily increasing.

For example, in the war against Iraq and Afghanistan, which operated high-speed explosives, they developed a variety of quasi-conventional weapons such as remote control type or rocket-type rapid explosive as well as booby trap type combined with advanced IT technology. As seen in the recent explosions in the boom at the Boston Marathon, the pattern of terrorism for the unspecified number of people will evolve and become even more evil.

In addition, the unmanned reconnaissance case can be used as a self-destructive terrorist equipment through remodeling and development at any time, even if the equipment is not highly accurate and high-performance equipment.

Therefore, we need more efficient, powerful and immediate on-site countermeasures against various forms of terrorist attacks using commercial communications networks. We will move away from the paradigm that has been dealt with until now, There is a demand for a solution.

Vehicle - mounted radio disturbing devices are mainly used to mount a radio disturbance device in a vehicle to block terrorist attacks using radio waves for national factors behind national factors.

The conventional vehicle-mounted radio disturbing apparatus uses a fuel for a vehicle to generate power to generate a radio wave disturbance device, and the radio disturbing apparatus is composed of 20 bands and 20 antennas In addition, since the structure is complicated and heavy as well as the noise generated from the generator is large and the vehicle fuel is used together, the pollution degree of the air inside the vehicle is high, so that it is not easy to operate the vehicle equipped with the radio disturbance device.

In addition, it is possible to apply only to a special vehicle of a van or more and to mount the vehicle in excess of the weight of the vehicle. Therefore, there is a need to fundamentally improve such a conventional on-vehicle radio wave disturbing apparatus.

In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

1 and 2, the present invention is a vehicle-mounted broadband radio disturbing apparatus mounted on a vehicle, which includes a battery 200 and a broadband radio disturbance signal generator 100 operated by receiving power from a battery, And an antenna 300 for transmitting a signal generated from the broadband radio disturbance signal generator 100. [ The battery 200 may be a lithium polymer battery pack. The battery 200 is small in volume but large in capacity, and is designed to greatly reduce the weight of the apparatus. In the present embodiment, two batteries 210 and 220 are used.

According to the embodiment of the present invention, the battery 200 and the radio disturbance signal generation unit 100 of the vehicular wave disturbance apparatus are accommodated by replacing the rear magnet in the rear magnet accommodating space of the vehicle, Can be mounted on a box. Accordingly, even if the vehicle-mounted radio disturbing apparatus of the present invention is mounted on the vehicle, it is difficult to recognize that the vehicle is externally available, so that the camouflage can be facilitated.

3 is a diagram showing a specific configuration of a radio wave disturbance signal generator 100 of an in-vehicle broadband radio wave disturbance apparatus according to an embodiment of the present invention. FIG. 3A is a plan view of a radio wave disturbance signal generator 100, FIG. 3B is a sectional view taken along line AA in FIG. 3A, FIG. 3C is a sectional view taken along a line BB in FIG. Each sectional view shows a cross section in a state in which the lower case and the upper case described below are folded.

The radio disturbing signal generator 100 is arranged to replace the rear magnet in the rear magnet accommodating space of the vehicle as described above and includes a radio wave disturbing assembly 113 having a plurality of radio wave disturbance modules M therein (110) having a lower case (111) and an upper case (112) that can be folded to each other, a connecting pipe (110) connected to the air conditioner cold air outlet of the vehicle 120 and an inlet guide 130 for guiding the cold air introduced through the connection pipe 120 to the case 110 and an outlet 150 through which the cold air is discharged through the case 110. [ And a discharge guide 140 for guiding the gas discharged from the case 110 can be further provided at a front end of the discharge port 150.

Since the radio wave disturbing assembly 113 having a plurality of radio wave disturbance modules M is accommodated in each of the lower case 111 and the upper case 112, the upper case 112 is folded with respect to the lower case 111, And is disposed so as to surround the outside of the disturbance assembly 113.

The lower case 111 includes a plurality of bottom fixing holes 111a for fixing the lower case to the floor of the vehicle and an upper case 112 is fixed to the lower case 111 And a fixing hook 111c may be provided on the other side of the lower case 111 so as to fix the folded upper case 112. [

In addition, a connection port 111d may be further provided at one side of the lower case 111 in the direction of the discharge port 150 to receive the antenna connection line so as to be electrically connected to the radio wave disturbance module M.

The radio wave disturbing assemblies 113 accommodated in the lower case 111 and the upper case 112 include a lower plate 113a and a lower plate 113b respectively coupled to the lower case 111 and the upper case 112 of the housing- Plate 113b and can be folded together when the lower case 111 and the upper case 112 are folded together. The plurality of radio wave disturbance modules M are coupled to the lower plate 113a and the upper plate 113b so as to face each other and the main heat sink S1 is provided outside the lower plate 113a and the upper plate 113b And the auxiliary heat sink S2 is provided on the upper part of the radio wave disturbance module M so that heat generated during operation of the radio wave disturbance assembly 113 can be efficiently dissipated.

A main board is provided in the lower case 111 to be electrically connected to each radio wave disturbance module M and a remote control unit RCU is provided in the upper case 112, Respectively.

Of course, the shape shown in this embodiment is merely an example, and it is also possible to construct the radio wave disturbance assembly 113 by being removably formed and inserted into the case-type case 110 for use.

Also, although the number of the radio wave disturbance modules M is shown to be 20 in the illustrated embodiment, the present invention is not limited to the illustrated number, (M) may be used.

The connection pipe 120 is connected to an air conditioner cold air discharge port (not shown) provided in the vehicle and serves to transmit the cold air generated from the air conditioner of the vehicle to the enclosure case 110 in the form of a circular pipe. Therefore, the heat generated in the case 110 can be easily cooled by using the air conditioner of the vehicle.

The inlet guide 130 guides the cool air introduced from the connection pipe 120 to the enclosure 110. The inlet guide 130 is formed in the shape of a circular pipe so that the outer diameter of the enclosure 120 in the direction of the enclosure 110 . A plurality of blowers B may be disposed at the boundary between the inlet guide 130 and the connecting pipe 120 to effectively introduce the air conditioner cooler.

A guide plate 132 is disposed on the inner side of the inlet guide 130 and spaced apart from the outer wall 131 so as to correspond to the outer side wall of the inlet guide 130 from a point where the outer diameter of the inlet guide 130 widens, Thereby forming a transfer path 133. The reason why the guide plate 132 is provided to guide the cool air upward and downward is that it is coupled to the radio wave disturbing device 1110 accommodated in the lower case 111 and the upper case 112 of the housing- And is for cooling the heat of the main heat sink S1 by rapidly introducing cool air into the main heat sink S1. It is preferable that the cool air is guided to the main heat sink S1 disposed in the lower case 111 and the upper case 112. It is preferable to prevent the air from flowing into the inner central portion where the radio wave disturbance module M is disposed, It is advantageous for protection of electric and electronic devices such as module (M).

The discharge guide 140 connects the case 110 with the discharge port 150 and may be formed to have a smaller diameter in the discharge port direction. It is also possible that the discharge guide 140 is omitted and only the discharge port is formed.

The discharge port 150 is attached to one end of the discharge guide 140 to discharge the air that has passed through the enclosure case 110 to the outside of the apparatus.

As described above, by installing a broadband radio disturbing device in a vehicle with a special structure and guiding the air conditioner cooler of the vehicle to cool the heat generated from the radio wave disturbance module M, the heat inside the vehicle is prevented from being excessively generated The use of a battery can significantly reduce the amount of noise generated.

Hereinafter, how the in-vehicle broadband radio disturbing apparatus according to the present invention operates will be described.

4 is a block diagram of the configuration of the radio wave disturbance module M and the antenna 300 of the in-vehicle type broadband radio disturbing apparatus according to the embodiment of the present invention. Referring to FIG. 4, each of the radio wave disturbance modules M ₁ , M _2, ... According to the embodiment of the present invention includes a controller 1110, a signal processor 1120, and an amplifier 1130 , Each radio wave disturbance module (M) generates a disturbance signal for the allocated band and transmits it through the antenna (300).

The control unit 1110 can control the signal processing unit 1120 and can take charge of communication with the outside. More specifically, it is possible to control a plurality of channels separately formed for the allocated band of each radio wave disturbance module M, and to control the output signal. In addition, a control signal for generating each channel signal can be output in accordance with the selection timing of each radio wave disturbance module M for each channel.

The control unit 1110 may output the corresponding channel selection signal to the signal processing unit 1120 according to the selection timing for each channel and the signal processing unit 1120 may output the corresponding channel selection signal to the signal processing unit 1120. In response to the channel selection signal of the control unit 1110, Thereby generating a channel signal. For example, when it is time to output a channel signal of 20 to 40 MHz among a plurality of channels in the range of 20 MHz to 100 MHz, the control unit 1110 outputs a channel selection signal corresponding to a channel signal output of 20 to 40 MHz to the signal processing unit 1120 Can be output. The signal processor 1120 may generate a channel signal of 20 to 40 MHz in response to the channel selection signal.

The signal processing unit 1120 generates a jamming signal of the corresponding channel corresponding to the channel selection signal received from the controller 1110 according to an embodiment of the present invention. For example, according to the embodiment of the present invention, the jamming signal may generate a jamming signal for each channel for a plurality of channels divided for one frequency band corresponding to the channel selection signal of the controller 1110. [

The signal processor 1120 may generate a corresponding channel signal according to a channel selection signal of the controller 1110 and transmit the generated signal at the same time.

The amplification unit 1130 amplifies the jamming signal for the channel output through the signal processing unit 1120 to a desired output signal.

The antenna 300 radiates the jamming signal amplified through the amplifier 130 into a free space.

The channel selection signal output from the controller 1110 may be randomly output to each of a plurality of channels included in the corresponding band sequentially or randomly. For example, when the first channel is divided into the first to sixth channels in the first band, the channel selection signals may be randomly output from the first channel to the sixth channel sequentially or randomly in a predetermined time period.

5, the signal processing unit 1120 of the radio wave disturbance module M generates a jamming signal for each channel as described above according to an embodiment of the present invention and includes a control voltage generating unit 1210, (VCO) 1230, a mixer 1240, and a noise signal generator 1250. The mixer 1240 and the mixer 1240 may be the same as those shown in FIG.

The VCO control voltage generator 1210, the sinewave generator 1220 and the noise generator 1250 are controlled by a control signal of the controller 1110 And generates a signal of a desired channel according to the selection signal. The control unit 1110 controls the digital signal according to a preset program to generate a VCO control voltage through the control voltage generating unit 1210 and generates a sinusoidal wave signal through the sinusoidal wave generating unit 1220. [ And generates a noise signal (for example, a white noise signal) through the noise signal generation unit 1250. Therefore, the center frequency and the frequency band for each channel of the jamming signal can be set by the control signal of the controller 1110. [ Therefore, by setting the center frequency and the frequency band for a plurality of channels, it is possible to implement the radio wave disturbance module M for each band.

For example, when the control unit 1110 outputs a channel selection signal for the first channel among the first to sixth channels constituting the first band, the control voltage generator 1210 generates a control voltage corresponding to the first channel Can be generated.

The sinusoidal wave generating unit 1220 generates a sinusoidal wave signal by considering a frequency band and a bandwidth of the selected channel according to a channel selection signal of the controller 1110 and a control voltage signal of the control voltage generator 1210, Lt; / RTI >

As described above, the sine wave generated by the sine wave generating unit 1220 is input to the VCO 1230, and the VCO 1230 can output the frequency band signal of the corresponding channel corresponding to the input sine wave. At this time, the center frequency is obtained by inputting the control voltage to the VCO 1230, and the frequency band of the corresponding channel is obtained by the sinusoidal wave input together with the VCO 1230.

The mixer 1240 mixes the frequency signal of the channel output through the VCO 1230 with the noise signal generated by the noise signal generator 1250 and outputs a jamming signal.

6 is a view for explaining a timing chart of channel operation for each band of the radio wave disturbance module M according to the embodiment of the present invention.

Referring to FIG. 6, when one band is divided into six channels, it is possible to selectively output each channel selection signal by switching the six channels in chronological order. However, since the present invention is not limited to the channel selection method shown in FIG. 6, it is needless to say that the channel selection signals can be randomly output in arbitrary order.

7 is a diagram illustrating band and channel configurations of a vehicle-mounted broadband radio disturbing apparatus supporting multiple bands with a plurality of radio wave disturbance modules M according to an embodiment of the present invention.

For example, as described above, a jamming signal of a corresponding channel is generated through a signal processing unit according to a channel selection signal of a control unit provided for each band for each channel, thereby generating a jamming signal of a desired band and channel.

For example, referring to FIG. 7, a band A may be composed of six channels (first to sixth channels). Likewise, the B-band, the C-band, and the D-band may be composed of six channels (first to sixth channels).

For example, the A-th band may be allocated to six channels within a first low band of 20 to 100 MHz, and the B-th band may be allocated to a second low band Six channels can be allocated in the frequency band of 700 MHz to 2700 MHz, which is the mobile communication band, and the D band (bands) can be allocated to six channels in a high-band frequency band of 2600 to 6000 MHz.

Thus, by combining the radio wave disturbance module M for each of the A to D bands, it can be used as a broadband radio wave disturbing device capable of disturbing broadband radio waves of 20 MHz to 6000 MHz, M) can be used.

In FIG. 7, it is shown that the four jamming signals are composed of six channels for each band for four bands, that is, four jamming modules M are provided. However, the present invention is limited to the above- It is not. It is also possible to operate with six or more channels for four bands.

In the conventional art, each jamming signal for each channel has to be switched and output by each RF switch. However, in the embodiment of the present invention, the control unit of each radio wave disturbance module M selectively generates and outputs a signal for each channel, Size and power consumption can be greatly reduced. Therefore, it is mounted on a vehicle and is easily available for wide-band propagation disturbance

Therefore, the apparatus to which the method according to the embodiment of the present invention is applied can be protected from the remote attack by the military, the police and the VIP protection security guards even when moving.

In addition, as described above, by supplying power to the device using the battery to the radio disturbing device mounted on the vehicle, it is possible not only to significantly reduce noise generation of the device and air pollution in the vehicle, but also to reduce the weight On-vehicle type broadband radio disturbing apparatus in which the efficiency of the apparatus is improved by facilitating the handling and inducing the cold air from the air conditioner of the vehicle to use for heat dissipation of the apparatus can be provided.
