Abstract

[Problem] To more appropriately set an exclusion zone or time wherein cellular phone usage restrictions which prevent explosives being detonated are carried out, and to appropriately carry out evacuation guidance. [Solution] When a notification is issued that a small explosion Bm has occurred, a security center identifies, from location information of the person issuing the notification, the location where the small explosion Bm has occurred, and transmits an alert directive signal to alert devices 10 which are within a given range centered on the location where the small explosion Bm has occurred (e.g., alert devices 10EA-10EG). Alert devices 10 receive the alert directive signal with a directive transceiver device 22, drive a jamming signal emitter 26, transmit jamming signals, and block radio waves from cellular phones, restricting the usage thereof. Detonations of explosives by remote control from cellular phones are thus prevented. Alert devices 10 drive a warning device 28, outputting warning sounds and lights, and indicate directions for evacuation by an evacuation direction indicator 30.

JP 2009-504108 A

However, in the background art described above, it is necessary to set a wide range of sensitive areas for a long time from the viewpoint of preventing damage. However, incidents and accidents may occur in addition to explosives, so it is better to limit the use of mobile phones to the minimum necessary.

The present invention pays attention to the above points, and its purpose is to more appropriately set the area and time for which the use of the mobile phone is restricted. Another purpose is to provide evacuation guidance appropriately. Still another object is to provide a storage container for appropriately storing a suspicious object.

The explosives warning system of the present invention is an explosives warning system that prevents the explosion of explosives initiated using radio waves, and is arranged in the area to be alerted at an interval that considers the range of radio wave blocking. , An explosives warning device that cuts off radio waves when a warning signal is received, and the warning device that is within a certain range from the position of the small explosion when a small explosion or explosive is detected. A command main body for transmitting a signal.

One of the main forms is characterized in that the explosives warning device is installed on either a mobile installation type column or an existing street light. One of the other forms is characterized in that the explosives warning device performs the radio wave blocking by jamming or relay stop. Alternatively, the explosives warning device performs the radio wave interruption by jamming or relay stop, and continues relaying for police or security communication when the relay stop is performed. Alternatively, the explosives warning device cuts off the radio wave by jamming or relay stop, and stops only incoming calls when the relay stop is performed. Alternatively, when the explosives warning device cuts off the radio wave by jamming or relay stop, and when stopping the relay, the mobile phone that has received an incoming call from a certain time of warning start to the time of the small explosion For incoming calls, incoming calls are allowed, and other incoming calls are stopped. Alternatively, the explosive warning device outputs a warning with light and / or sound when the radio wave is cut off. Alternatively, the explosives warning device indicates an evacuation direction.

The explosives warning device according to the present invention is used in any one of the explosives warning systems described above, and is arranged in the area to be watched at an interval considering the range of radio wave blocking. It is characterized by blocking.

The explosive detection sensor of the present invention is an explosive detection sensor for detecting explosives from a suspicious object in any one of the explosive warning systems, wherein the sensor detects a metal and a weak radio wave from the suspicious object. And a communication means for notifying the commanding subject that the explosive has been detected.

The container for suspicious objects of the present invention has an electromagnetic shielding function for blocking radio waves from the outside, or stretches a protective cloth having impact resistance so that it can be opened and closed, and covers the suspicious object with this protective cloth, The protective cloth having the electromagnetic shielding function and having the shock resistance is stretched so as to be freely opened and closed, and the suspicious object is covered with the protective cloth.

One of the main forms is characterized by comprising sensor means for performing at least one of metal detection, weak radio wave detection, and sound detection on the suspicious object.

It is a figure which shows Example 8 of this invention. It is a figure which shows Example 8 of this invention.

Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

FIG. 1 shows the overall configuration of the first embodiment. First of all, the outline is that the criminal tries to set up the explosives in a place where many people gather, but there is a high possibility that they will be discovered because there are many people. Therefore, a small explosion is first executed to attract people's attention. And while the attention of people and security officials is on their side, the main explosives are set at the target location. After that, the main explosive is blown away from the site using a mobile phone.

To prevent this, for example, if the use of mobile phones is restricted for each base station, the range becomes wide. Therefore, in the present invention, a large number of warning poles are installed in a place where many people gather, and a warning device having a jamming function for disturbing radio waves of a mobile phone is installed in this, so that limited use is restricted. Yes. When there is a small explosion, it is highly likely that a major explosive will be set up nearby. Therefore, the mobile phone is jammed at the warning pole in the warning area (see the dotted line) where the small explosion occurred and at a certain distance from the warning pole in the adjacent warning area, for example. By doing in this way, it is not necessary to perform use restriction over a wide range, and the use restriction time can be shortened.

Fig. 1 shows the situation. For example, if a small explosion Bm occurs and is reported to the security headquarters by a police officer or the like (see arrow FA), the security headquarters 50 (or the operation headquarters or the police station or the command subject in charge) Then, it instructs the warning devices 10EA to 10EG within a certain range from that position to perform jamming (see arrow FB). Then, the radio waves of the mobile phone are disturbed in the warning area of the warning devices 10EA to 10EG, and the use is restricted. Even if the main explosive BM is set within the range of the warning device 10EG, the radio wave of the criminal's mobile phone is obstructed by jamming, and the explosion is prevented.

Furthermore, in the present invention, the warning device is provided with a light and sound alarm device to warn people that there is a risk of explosion. A direction indicator is also provided to indicate the direction of evacuation.

FIG. 2 shows an example of the above-described warning devices 10EA, 10EB, 10EC,. In the figure, the warning device 10 is attached to a column (warning pole) 14 erected on a movable installation type base 12. A battery necessary for driving is built in the base 12. Moreover, the street lamp 16 is provided in the support | pillar 14 if needed.

The warning device 10 includes the following devices.
a, a command transmitter / receiver 22 that receives an operation command signal from the security headquarters 50 or the like or transmits a command signal indicating that the warning button 24 has been pressed;
b, Warning button 24 to be pressed when an incident / accident occurs,
c, a jamming signal transmitter 26 for outputting a jamming signal based on reception of the operation command or operation of the warning button 24;
d, an alarm device 28 for outputting an alarm (sound or light) based on reception of the operation command or operation of the warning button 24;
e, an evacuation direction indicator 30 for instructing an evacuation direction based on reception of the operation command or operation of the warning button 24;
f, a surveillance camera 32 for the security headquarters 50 to monitor the surroundings and store images;

The warning device 10 is installed at a place where warning is necessary at an interval considering a warning area where jamming is possible. For example, when a marathon event is held, it is arranged at appropriate intervals along the course. When installing, the base 12 may be provided with a caster to be movable, or the base 12 may be embedded in the ground. Also, only the warning device 10 is mounted on the vehicle to use the power source of the vehicle, installed on an existing street light to use the power source of the street light, or installed on the outer wall of the building to use the power source in the building. For example, various modes may be adopted.

Next, the operation of this embodiment will be described. For example, assume that a small explosion Bm has occurred as shown in FIG. When this is reported to the security headquarters 50, the security headquarters 50 identifies the location where the small explosion Bm occurred from the location information (GPS information) of the reporter, and a certain range of the warning device 10 (for example, the center) (for example, A warning command signal is transmitted to the warning devices 10EA to 10EG).

Then, the warning device 10 receives the warning command signal by the command transmitter / receiver 22 and performs the following operation.
a. The jamming signal transmitter 26 is driven to transmit a jamming signal, obstruct the radio wave of the mobile phone, and restrict use.
b. The alarm device 28 is driven to output an alarm sound or light.
c, The evacuation direction is instructed by the evacuation direction indicator 30. In the example of FIG. 1, the direction opposite to the direction in which the small explosion Bm was present is indicated. The criminal is thought to attract attention by a small explosion Bm and install the main explosive BM in that space. Therefore, since the installation position is considered to be a position relatively close to the small explosion Bm, the direction away from the position of the small explosion Bm is set as the evacuation direction.

If the warning button 24 is pressed instead of reporting to the security headquarters 50, the operations a to c are performed, and the command transmitter / receiver 22 notifies the security headquarters 50 to that effect. In this case, the position information of the warning device 10EA where the warning button 24 is pressed is included in the content of the report to the security headquarters 50. The security headquarters 50 specifies the position where the small explosion Bm has occurred from the position information of the warning device 10EA, and sends a warning command signal to a certain range of warning devices 10 (for example, warning devices 10EB to 10EG). Send. Thereafter, the above-described jamming and alarm operations are performed.

As described above, according to the present embodiment, the small explosive Bm is detected and jamming is performed around it to prevent the explosion of the main explosives. Can be set more appropriately. In addition, since the direction away from the small explosion Bm is indicated as the evacuation direction, the evacuation guidance can be performed appropriately.

Next, Embodiment 2 of the present invention will be described with reference to FIG. According to the above-described embodiment, the explosion of the main explosive material is prevented by interfering with the radio wave of the mobile phone based on the instruction from the security headquarters, but in this embodiment, the relay function of the mobile phone is stopped. By doing so, the same effect is obtained.

In the figure, the warning device 100 of the present embodiment includes a mobile phone repeater 110 and a relay antenna 112 that relay radio waves of the mobile phone 60 in addition to the warning device 10 of the first embodiment. The mobile phone repeater 110 is buried in the ground if necessary. The mobile phone repeater 110 includes not only a relay between the mobile phone 60 and the base station 70 but also a relay stop unit 111 that stops the relay based on the warning command signal shown in the first embodiment. A plurality of the warning devices 100 are installed at intervals considering the relay range by the mobile phone repeater 110 and cover the warning area.

Next, the operation of this embodiment will be described. In a normal state, the mobile phone 60 and the base station 70 are relayed by the mobile phone repeater 110. Here, as shown in FIG. 1, when a small explosion Bm occurs and is reported to the security headquarters 50, the security headquarters 50 identifies the position where the small explosion Bm has occurred from the location information (GPS information) of the reporter. At the same time, a warning command signal is transmitted to the warning device 100 within a certain range centered on the warning command signal.

Then, in the alert device 100, the alert command signal is received by the command transceiver 22, and the mobile phone repeater 110 performs the following operation.
a. For the general mobile phone 60, the relay stop unit 111 stops the relay.
b. Alternatively, the mobile phone number of the police or security officer is registered in advance in the relay stop unit 111, and the relay is continued in them.

That is, in Example 1 described above, all the mobile phones 60 are not connected due to jamming. However, according to the present example, the mobile phone 60 of the police or the security officer can communicate and communicate as usual, Inconvenience due to jamming is improved. In addition, the point which outputs a warning sound and light, the point which supports an evacuation direction, and the operation | movement when the warning button 24 is pushed instead of the report to the security headquarters 50 are the same as that of the said Example.

As modifications of the present embodiment, there are the following modes.
a, The mobile phone repeater 110 stops only incoming calls in the alert area. Thereby, the initiation of the main explosive BM can be prevented. According to this method, the incoming call is stopped, but the outgoing call outside the warning area is not stopped, so that it is possible to contact the outside.
b, It can be considered that the incoming call to the mobile phone for detonating the main explosive BM is performed after the small explosion Bm. As a result, it is not necessary to stop the incoming call after a small explosion Bm for a mobile phone that has received an incoming call in the warning area from a certain time after the start of the warning until before the small explosion Bm. Therefore, the telephone number of the mobile phone that has been received from a certain time from the start of warning to the time of the small explosion Bm is recorded by the relay stop unit 111 of the mobile phone repeater 110, and the incoming call to the number is recorded after the small explosion Bm. Allow. In addition, about transmission, it is the same as that of the aspect of said a.
c. When the number of the mobile phone used in the past in the explosion case is known, the number is registered in advance in the relay stop unit 111 of the mobile phone repeater 110, and the transmission is stopped.

Next, Embodiment 3 of the present invention will be described with reference to FIG. The third embodiment relates to an improvement of a countermeasure when a suspicious object is found. At present, when a suspicious object with the possibility of explosion is discovered, it is confirmed whether it is an explosive using a police dog, metal detector, X-ray, etc. While being used, the suspicious object is stored in the storage container with a magic hand or the like and cooled or frozen. Then, after moving to a safe place, blasting is performed.

The explosive detection sensor according to the present embodiment has a function suitable for determining whether a suspicious object is found or not. FIG. 4 (A) shows the appearance thereof, and the explosive detection sensor 200 has a configuration in which a loop 220 is provided on a handle 210. The handle 210 includes a drive power supply 212 and a power switch 214. The loop 220 incorporates a metal detection coil 222, a sensor array 224 for detecting weak radio waves of a mobile phone, a detection lamp 226 indicating a detection intensity, a detection buzzer 228, and a detection control circuit 230. It has been.

The size of the loop 220 is set to a size that can surround the detection target 202, for example, as shown in FIG. As the detection target 202, a trash can, a bag, etc. are assumed, for example. As the sensor array 224, a sensor for detecting a weak radio wave emitted from a mobile phone or a sensor for detecting a sound of a timer is assumed. Which sensor is used can be appropriately switched. Furthermore, the explosive detection sensor 200 of the present embodiment includes a communication device 232, and when this is detected as an explosive, the fact is transmitted to the security headquarters 50 and the above-described warning device 100. It has become.

Next, the operation of the present invention will be described with reference to FIG. For example, it is assumed that a suspicious object 290 as shown in FIG. 4C is found on the side of a road, and an explosive 292 and a detonator 294 are accommodated in the suspicious object 290. When the suspicious object 290 is sensed using the explosive detection sensor 200,
a, When the suspicious object 290 contains metal, it is detected.
b. When a cellular phone is included in the detonator 294, the weak radio wave is detected.
c. When a timer is included in the detonator 294, the sound is detected.

Then, the detection control circuit 230 turns on or blinks the detection lamp 226 and sounds the detection buzzer 228. Further, the fact that the explosive is detected is transmitted to the security headquarters 50 and the above-described warning device 100 by the communication device 232 automatically or manually. Subsequent operations are the same as those in the first and second embodiments. As described above, the suspicious object 290 is accommodated in the accommodating container and subjected to the blasting process after the movement.

As described above, according to the sensor of the present embodiment, since it has a function necessary for detecting explosives, it can be well detected whether explosives are stored in a suspicious object. And evacuation guidance can be performed promptly. When any of the explosive detection sensors 200 performs the above detection, the communication device 232 may notify the other explosive detection sensors 200 to that effect.

Next, Embodiment 4 of the present invention will be described with reference to FIG. For example, when the suspicious object 290 is found by the method of the third embodiment described above, it is necessary to perform jamming as in the first embodiment or relay stop as in the second embodiment so that the suspicious object 290 does not explode. However, it is preferable to cancel the communication interruption as soon as possible. Therefore, in the embodiment of FIG. 5A, the found suspicious object 290 is accommodated in the electromagnetic shield container 300. The entire electromagnetic shield container 300 including the main body 301 and the lid 302 is made of a conductor such as copper and has a function of shielding radio waves. By accommodating the suspicious object 290 in the electromagnetic shielding container 300, the invasion of the radio wave of the mobile phone from the outside is blocked. For this reason, jamming and relay stop can be canceled. As a precaution, a small jamming signal transmitter 310 may be provided in the electromagnetic shield container 300.

5B is an example in which the above-described small jamming signal transmitter 310 is carried by a worker 320 who discovers and stores a suspicious object. It is sufficient that the jamming signal transmitter 310 has a function of allowing jamming radio waves to reach within a range of, for example, several tens of meters as a distance. By doing so, it is possible to prevent the suspicious object 290 from exploding near the worker 320 even when jamming or relay stop is not performed as in the above-described embodiment.

The embodiment of FIG. 5 (C) is an example of a storage container that stores the suspicious object 290. In the figure, the container 400 contains a ring-shaped explosive detection sensor 410, and a fluoroscope 420 and a communication control device 430 are provided on the side. Further, a lid 402 is provided and is driven to open and close by a motor 404. Similar to the electromagnetic shielding container 300 described above, the storage container 400 is also made of a conductor so as to have an electromagnetic shielding function.

Among these, the explosive detection sensor 410 has the same function as the explosive detection sensor 200 of FIG. 4 described above, and can detect a metal or a weak radio wave. The fluoroscopy device 420 is for seeing through the inside of a suspicious object using, for example, X-rays. The communication control device 430 is for performing remote control operations of the above-described units and outputting detection results, and is connected to the antenna 432.

Next, the operation of this embodiment will be described. When the storage container 400 is used, a signal is transmitted so that the lid 402 of the storage container 400 is opened by a remote control operation. When this signal is received by the antenna 432, the motor 404 is driven by the communication control device 430 and the lid 402 is opened. In this state, the suspicious object 290 as shown in FIG. 4 is accommodated in the container 400, and the remote controller is operated again to close the lid 402.

Next, a remote control operation is performed to perform sensing by the explosive detection sensor 410, and the inside of the suspicious object 290 is seen through by the see-through device 420. As a result, when it is recognized that there is an explosive substance in the suspicious object 290, the container 400 is transported to a safe place, and the fact that the explosive substance is detected by the communication control device 430 is described in the security headquarters 50 and the above-mentioned. It is transmitted to the warning device 100. Subsequent operations are the same as those in the first and second embodiments. Thus, a simpler process can be performed by providing the container with an explosives detection function.

You may make it combine the Example mentioned above. For example, it is assumed that the worker 320 carrying the jamming signal transmitter 310 of FIG. 5B finds the suspicious object 290 using the explosive detection sensor 200 shown in the third embodiment of FIG. The worker 320 accommodates the suspicious object 290 in the electromagnetic shield container 300 shown in FIG. And the suspicious object 290 is accommodated in the storage container 400 shown in FIG.5 (C), and it confirms that it is an explosive.

Next, Embodiment 5 of the present invention will be described with reference to FIG. The present embodiment is an example in which the present invention is applied to an aircraft. In the aircraft 500, for example, communication is performed between the in-flight mobile phone 510 and the ground equipment 512 such as an exchange through the in-flight base station 502, the mobile communication satellite 504, and the ground station 506 by a leak cable installed in the airplane. Is to be done.

At present, it is not possible to bring a suspicious object 290 into the aircraft 500 or in the cargo compartment by a prior inspection, but if it is brought in by any method, it may explode due to an incoming call from a mobile phone. is there.

Therefore, in this embodiment, the operation of any one of the following modes is performed.
a, Only incoming calls are stopped by the in-flight base station 502. Thereby, the initiation of the suspicious object 290 can be prevented. According to this method, the incoming call is stopped, but the outgoing call is not stopped.
b. The in-flight mobile phone 510 that received an incoming call from a certain time before the start of warning until the aircraft 500 takes off can be considered not to be a remote control for detonation, and it is not necessary to stop the incoming call after takeoff. Therefore, the telephone number of the in-flight mobile phone 510 received from the start of boarding to take-off is recorded in the in-flight base station 502, and the incoming call for the number is allowed after take-off. Note that the outside call and the like are the same as in the case of a.
c. When the mobile phone number used in the past in the explosion case is known, the in-flight base station 502 stops sending the number.
d, the in-flight base station 502 is stopped, and both outgoing calls from the airplane and incoming calls from outside the airplane are stopped. In this case, it can be considered similar to the jamming.

In addition, as in the above-described embodiment, outgoing and incoming calls for police or security may be performed as usual. Further, instead of the in-flight base station 502, the incoming call may be stopped on the ground facility 512 side. The present embodiment can be similarly applied to various moving bodies such as ships and vehicles (bullet trains) in addition to the above-described aircraft.

Next, Embodiment 6 of the present invention will be described with reference to FIG. This embodiment is a simplified version of the above-described embodiment of FIG. As shown in FIG. 7 (A) as a whole, the explosive material storage device 600 includes a housing 602 whose bottom surface is open and a bottom lid 604 that covers the bottom surface of the opening. A handle or handle 606 for carrying the housing 602 is provided on the top surface of the housing 602. In addition, a flange 608 for coupling to the bottom lid 604 is provided at the lower part of the housing 602.

A sensor array 630 is provided in the housing 602. Similar to the above embodiment, the sensor array 630 has a function of detecting weak radio waves, sound, or metal from the suspicious object 290. If there is a timer or electronic circuit for initiation, the sensor array 630 can detect them. Detected. The operation of the sensor array 630 is performed by operating the operation switches 612 of the operation plate 610, and the detection result is displayed on the display device 614.

On the other hand, a fluoroscopic device 632 using X-rays or the like is provided on the bottom lid 604 side so that a fluoroscopic image of the suspicious object 290 is projected onto a film or display 634 provided on the top surface of the housing 602. It has become. Note that the fluoroscopic device 632 may be provided on a side surface of the housing 602, or a fluoroscopic image may be displayed on the display device 614.

Furthermore, the housing 602 is provided with a valve 640 at an appropriate position. For example, a liquid nitrogen cylinder 642 can be connected to the valve 640, and liquid nitrogen is introduced into the housing 602 to operate the detonator (including detonation electronic circuit) by freezing. It can be impossible.

Next, the operation of this embodiment will be described. When the suspicious object 290 is found, as shown in FIG. 7B, the suspicious object 290 is placed on the bottom cover 604, covered with the housing 602, and fixed to the flange 608 with a bolt 650 or the like. As a result, external detonation radio waves are blocked.

Next, the switches 612 are operated, and the suspicious object 290 is sensed by the sensor array 630 and the fluoroscopic device 632. As a result, when it is determined that it is an explosive, a liquid nitrogen cylinder 642 is connected to the valve 640 and liquid nitrogen is introduced into the housing 602. As a result, the detonator is frozen and the explosion is prevented. Note that a series of these operations may be programmed so as to be automatically performed in a preset order, so that a self-contained system may be obtained. In addition, communication means for the police or the like may be provided as in the above embodiment.
