  FIG. 1 shows an outline of an example of the best mode of an evacuation guidance system (apparatus) according to the present invention, and FIG. 2 shows a leaky coaxial cable with an IC tag and a mobile phone with an emergency drive function used in this system. FIG. 3 shows a schematic configuration of a mobile phone with an emergency drive function, and FIG. 4 shows an example of a laying state of a leaky coaxial cable of this system.

  In FIG. 1, reference numeral 100 denotes an entire evacuation guidance system having a built-in computer system and, if necessary, connected to an external network. Reference numeral 200 denotes, for example, a control room (management room) that forms a section in a facility of an underground passage. It is an evacuation guidance device installed on the 110 side.

  In the case of this example, the evacuation guidance device 200 is a combined type device that also includes a normal driving unit. The main control unit 210 of this apparatus is a part that also serves as a normal driving unit, and the emergency control unit 220 is a part that copes with an emergency (a hardware configuration, a program configuration, or a mixed configuration of both is also possible). is there. For example, an antenna circuit unit 211 and a broadcast circuit unit 212 are attached to the main control unit 210. The antenna circuit unit 211 allows the leaky coaxial cable 300 laid in the underground passage facility to function as an antenna for a mobile phone or the like. The broadcast circuit unit 212 is for making a desired audio broadcast (announcement) in the underground passage through the broadcast cable 400 or the like. Although not shown, in the case of audio guidance broadcasting, a speaker is connected to an appropriate location on the broadcasting cable 400.

  A leaky coaxial cable 300 with an IC tag shown in FIG. 2 includes a support part (messenger wire part) 310 for suspending the cable itself, a coaxial cable part 320, and an IC tag (an antenna part and an IC chip part having a power supply part). (Ordinary) 330. The coaxial cable portion 320 is composed of, for example, a central inner conductor 321, an insulator 322, an outer conductor 323, a sheath (outer skin) 324, and the like, and in particular in the longitudinal direction of the outer conductor 323 portion, a slit for signal leakage of radio waves and electromagnetic waves. Many (notches) 323a are provided (indicated by a solid line in the figure, but formed under the sheath). A number of IC tags 330 are also provided in the longitudinal direction of the outer conductor 323 portion in the slit 323a or in the vicinity thereof. The insulator 322 may be a structure in which a space forming string is wound or a foamed insulator such as foamed polyethylene for weight reduction.

  In this leaky coaxial cable 300, radio wave and electromagnetic wave signals are appropriately leaked from the signal leakage slit 323a, so that the mobile phone 500 with the emergency drive function for the present invention is not limited to a normal mobile phone. As described above, the telephone also functions as an antenna. At the same time, the IC tag 330 can be driven by a leak signal from the leaky coaxial cable 300 in an emergency.

  A mobile phone 500 with an emergency drive function according to the present invention is, for example, as shown in FIG. It has a mobile phone main body 510 which is a normal mobile phone function part, and an attached emergency drive function unit 520 (in addition to a hardware configuration, a program configuration or a mixed configuration of both is also possible). The emergency drive function unit 520 includes an emergency signal receiving unit 521 that receives an emergency signal transmitted from the evacuation guidance device 200 side in an emergency via the IC tag 330 and a unique signal ( A unique signal transmission unit 522 for transmitting an ID signal (for example, a mobile phone number or personal information of the telephone holder) is attached. This unique signal is also transmitted to the escape guiding apparatus 200 side via the IC tag 330. For this reason, an IC tag corresponding portion 523 for an IC tag is attached. Each of these units may be a hardware configuration, a program configuration, or a mixed configuration.

  That is, the evacuation guidance apparatus 200 and the mobile phone 500 function as a kind of reader / writer with respect to the IC tag 330 at an appropriate location of the leaky coaxial cable 300. The emergency signal from the evacuation guidance device 200 is temporarily stored in the IC tag 330 and read by access from the mobile phone 500. Conversely, the unique signal from the mobile phone 500 side is temporarily stored in the IC tag 330 and read by access from the evacuation guidance apparatus 200.

  Since the IC tag 330 that performs such a relay station function is in close proximity to the evacuation guidance apparatus 200 through the leaky coaxial cable 300, the frequency level of the emergency signal can be handled in the MHz band, for example, about 10 MHz. it can. On the other hand, since it is necessary to be able to communicate from a position considerably away from the mobile phone 500 side, the frequency level of the specific signal needs to be handled in the GHz band, for example, about 2.5 GHz. If it is about 2.5 GHz, sufficient communication is possible even if the distance between the IC tag 330 and the mobile phone 500 is about 5 m. Note that power charging on the IC tag 330 side is performed for access from the evacuation guidance apparatus 200 and the mobile phone 500.

  Corresponding to the mobile phone 500 as described above, the emergency control unit 220 on the evacuation guidance apparatus 200 side includes an emergency memory 221, an identification inquiry unit 222, a position calculation unit 223, an evacuation unit, as shown in FIG. A route search unit 224 and an IC tag corresponding unit 225 are attached. Each of these units may be a hardware configuration, a program configuration, or a mixed configuration.

  The IC tag corresponding part 225 is for corresponding to the IC tag 330 of the leaky coaxial cable 300. As described above, since communication between the evacuation guidance apparatus 200 and the mobile phone 500 is performed via the IC tag 330, these are matched.

  The emergency memory 221 is a memory in which various data and programs necessary for evacuation guidance are stored. The identification inquiring unit 222 collates a unique signal (such as an ID signal) from the mobile phone 500 side with, for example, data stored in the emergency memory 221 to identify the personal information (identity) of the owner. is there. For example, when the specific signal is a mobile phone number, it is possible to store the mobile phone number database in the emergency memory 221 in advance, but this evacuation guidance system 100 is connected to an external network (telephone company network). Etc., it is possible to link with a wider range of mobile phone number databases. The unique signal may be a telephone holder's pension number or the like.

  The position calculation unit 223 transmits an emergency signal from the evacuation guidance device 200, and thereby arrives at a specific signal transmitted from the specific signal transmission unit 522 of the activated mobile phone 500 via the IC tag 330 at regular intervals. The time is calculated to calculate the position information of the telephone holder. That is, the length of the leaky coaxial cable 300 portion can be calculated from the time difference between the emergency signal transmission time from the evacuation guidance device 200 and the arrival time of the specific signal transmitted from the specific signal transmission unit 522 of the mobile phone 500. The location information of the phone holder can be obtained.

The evacuation route search unit 224 guides evacuation by distributing a large number of disaster victims to a plurality of exits (evacuation exits) in a facility such as an underground passage.
That is, when the location information of a large number of mobile phones 500 calculated by the location calculation unit 224 is accumulated, it is possible to know how many disaster victims are present in which part of the facility. 224 makes it possible to find the optimum evacuation route.

  For example, the inside of a facility such as an underground passage is generally T-shaped passages 601 to 603 as shown in FIG. Note that reference numerals 611 to 613 denote exits (evacuation exits), and 300 denotes a leaky coaxial cable installed in this portion. In this case, since the sample facility structure is simple, in finding the optimum evacuation route, the evacuation route search unit 224 does not calculate and search, but which part of the victim evacuated from which exit 611 to 613 Data such as whether it is better is obtained. Therefore, facility managers, fire fighters, and the like can perform optimal evacuation guidance based on this data.

  In addition, if an emergency signal is sent from the evacuation guidance device 200 side by means of text information or the like, data such as the status of the occurrence of an abnormality, the location of the exit, the number of victims, etc. can be transmitted to the mobile phone 500 side. By referring to these information, it is possible to take the optimum evacuation action by oneself. Of course, if the system can transmit image information to the mobile phone 500 as an emergency signal, the disaster victim can use this as more reliable reference information.

  In the evacuation guidance system 100 according to the present invention having such a configuration, as described above, since it is a combined device for normal time and emergency, the leaky coaxial cable 300 is used as an antenna for a mobile phone or the like in normal time. It is used as a device for audio broadcasting (announcement) through a broadcasting cable 400 or the like.

  However, once an emergency such as a fire occurs, the evacuation guidance system 100 according to the present invention functions as an evacuation guidance system. First, when an emergency such as a fire is grasped on the control room 110 side, the evacuation guidance device 220 is driven to transmit an emergency signal and flow (input) to the leaky coaxial cable 300 side.

  Then, the mobile phone 500 of a victim who is in a facility such as an underground passage and encounters a fire, that is, a telephone holder, is activated via the IC tag 330. This activation is dealt with by the telephone holder in advance by performing an appropriate operation, for example, by operating a button such as # 1 or #K to drive the emergency drive function unit 520, or if the power is on. It is also possible to cope with the constant emergency drive function unit 520 so as to be in a startup standby (OK) state.

When the emergency drive function unit 520 is driven, an alarm sound, an alarm character, an alarm image, or the like is generated or displayed from the mobile phone 500 in response to the emergency signal. A certain amount of information can be obtained quickly. At this time, the power source is the mobile phone 500 at hand because the facility has a power outage or is filled with smoke, and the information source is the mobile phone 500 at hand. And can contact emergency information. The same is true for many other telephone holders.
Therefore, a great sense of security and important judgment materials are given to individual telephone holders, and an effect of preventing the occurrence of a panic can be obtained for a group of a large number of telephone holders.

  On the other hand, by the driving of the emergency drive function unit 520, a unique signal (ID signal) of the telephone holder is transmitted from the mobile phone 500 side, for example, at regular intervals. This unique signal is picked up (input) to the leaky coaxial cable 300 side via the IC tag 330 and transmitted to the evacuation guidance device 220 side.

  Since the leaky coaxial cable 300 may break due to the occurrence of this emergency situation, the evacuation guide device 220 may be installed not only at one end side of the leaky coaxial cable 300 but also at both end sides. Furthermore, when the underground passage in the facility has a more complicated knitted structure, the leaky coaxial cable 300 is also laid in a knitted pattern, and the evacuation guidance devices 220 are also installed in a plurality of places as appropriate. Good. Thereby, even if the leaky coaxial cable 300 is partially broken, the cable function is sufficiently secured. Further, even if the leaky coaxial cable 300 is broken by the IC tag 330 and completely destroyed, the emergency signal information stored in the IC tag 330 remains as it is. If the IC tag 330 is accessed from the mobile phone 500 side, emergency signal information can be obtained, so that the minimum emergency signal information can be read.

  When the unique signal is received on the evacuation guidance device 220 side, the identification inquiry unit 222 identifies and inquires the information content of the unique signal. For example, when the unique signal is a mobile phone number or an annuity number, personal information of the telephone holder, that is, the victim is obtained. Therefore, on the basis of this, the control room 110 side can quickly and accurately transmit information to related parties such as the family of the telephone holder and the company employed.

  Further, the position calculation unit 223 obtains the position information of the telephone holder, that is, the victim. In other words, you can see where the victim is in the facility such as underground passage. Further, when the location information of a large number of victims is obtained, it is possible to know how many disaster victims are located in which part of the facility, so that this evacuation route search unit 224 finds the optimum evacuation route. be able to. Accordingly, facility managers, fire fighters, and the like can quickly proceed with optimal evacuation guidance measures based on this data.

  Furthermore, the emergency information on the control room 110 side obtained in this way can be sent back to the mobile phone 500 side for feedback. As a result, as described above, individual telephone holders are given a great sense of security and important judgment materials, and a large number of telephone holders have the effect of preventing the occurrence of panic. can get.

  In the above embodiment, the description has been made centering on facilities such as underground passages, but the present invention is not limited to underground passages and the like, and is also applicable to facilities such as underground spaces, passages, and tunnels in buildings. be able to.
