Description

  The present invention relates to a tunnel guide facility in which guide display plates are arranged along a tunnel side wall.

  Conventionally, emergency facilities have been installed in tunnels for exclusive use of automobiles and the like in order to protect people and vehicles from fire accidents that occur in the tunnel.

  Such emergency facilities are equipped with fire detectors, manual reporting devices, emergency telephones for fire monitoring and reporting, fire hydrant devices for fire extinguishing and fire spread prevention, In order to protect the inside of the duct from a fire, a water spray that sprays water for fire extinguishing from the water spray head is installed, and a guidance facility with a guidance display board showing the direction and distance of the tunnel exit and evacuation contact is installed In addition, a tunnel disaster prevention system has been constructed by providing a disaster prevention reception panel that monitors and controls the terminal equipment of these emergency facilities.

  Among these, in the guidance facility, the guidance display board shown in FIG. 11 is installed along the tunnel side wall at a predetermined interval.

  FIG. 11A shows a guidance display board 100A installed in a tunnel without an evacuation communication mine, which is 60 centimeters high and 120 centimeters wide, and indicates a left and right guiding direction 102a in green with respect to a white background. , 102b, the number of distances 106a, 106b to the exit are displayed below, and a pictogram 104 representing the evacuation guidance in the form of a graphic between the arrows 102a, 102b and a character display section 108 of “exit EXIT” are displayed. The pictogram 104 is directed toward the shorter distance number.

  The guidance display board 100A includes a reflection type and an internal illumination type. The reflection type is a plate member made of aluminum alloy, and a capsule lens shape is used as a reflection sheet. In the internal illumination type, the display surface is made of tempered glass, and a fluorescent lamp is disposed as an internal light source, for example, to perform backlight illumination.

  The guide display plate 100A is installed at a height of 1.5 meters from the road surface for tunnels without evacuation pits, and staggered at 100-meter intervals alternately on the side walls of the tunnel on the border of the tunnel. Arrange.

  FIG. 11B shows a guidance display board 100B installed in a tunnel having an evacuation communication mine, which displays the distance number to the evacuation communication mine or the exit as the distance numbers 106a and 106b, and the character display of “emergency exit EXIT”. 112 is different, except for the above, which is basically the same as FIG.

  Installation of the guidance display board 100B for tunnels without evacuation communication pits is done at a height of 1.5 meters from the road surface, and in the vicinity of the evacuation communication mine and in the middle so that the distance does not exceed 100 meters. The other sections are arranged in a staggered arrangement with an interval of 100 meters alternately with respect to the tunnel side walls on both sides.

  However, the conventional guidance equipment only installs a guidance display plate and displays the direction of the exit and the evacuation connection mine and the number of distances in a fixed manner. When a fire occurs in a tunnel, for example, When the visibility inside the tunnel becomes poor due to the smoke generated by the above, it becomes difficult to visually recognize the guidance display board, and it may be difficult to perform quick and appropriate evacuation guidance.

  In order to solve this problem, a guidance device is integrated with emergency facilities such as fire detectors and fire hydrants installed in each section of the tunnel, and the direction of evacuation is determined based on a transfer signal received from the outside. The arrow shown is blinked and guidance information is output, enabling quick and appropriate evacuation guidance (Patent Document 1).

  The circuit boards 54a and 54b are arranged on the main body 72b side opposite to the movement display parts 48a and 48b, and relative to the six triangular marks 48 drawn on the movement display parts 48a and 48b on the circuit boards 54a and 54b. Then, the LED 56 that functions as a light source is mounted, the periphery thereof is surrounded by a partition 58, the front of the LED 56 is opened, and light by driving the LED 56 can be irradiated forward.

  When the controller 60 shown in FIG. 5 is mounted on the circuit boards 54a and 54b and a control signal is received from the disaster prevention receiving board 10, any one of the guidance display controls shown in (1) to (3) above is controlled. Do the same.

  In this way, the composite guidance display board 72 is installed separately in addition to the effects of the guidance display board and the dynamic guidance display device by providing the function of the dynamic guidance display device integrally with the guidance display board of the internally illuminated structure. Compared to the case, the facility work is simplified, and the work such as inspection can be facilitated.

  FIG. 8 is an explanatory view showing another embodiment of the composite induction display board in which the functions of the dynamic induction display device are integrated. As shown in FIG. 8, the composite guidance display plate 72 of the present embodiment has a pictogram on the surface of the tempered glass that becomes the dynamic guidance display section 76 disposed on the upper portion of the cover 72a in green with respect to the white background, and the movement display mark. The movement mark 70 is used, and for example, four pictogram movement marks 70 are arranged in the guiding direction. Also in this case, in addition to the effects of the guidance display board and the dynamic guidance display device, the facility work becomes simpler than the case where they are installed separately, and the work such as inspection can be facilitated.

  In addition to this, the embodiment of the composite induction display board in which the functions of the dynamic induction display apparatus are integrated is different from the induction non-display board 12 in that the dynamic induction display apparatus 14 is arranged on both upper and lower sides, right side, left side, and left and right sides. Also in the case of separate arrangement, they may be similarly integrated.

[Guidance display as a whole tunnel]
FIG. 9 is an explanatory diagram showing the address, group number, and guidance pattern of the dynamic guidance display device in guidance display control when a fire has occurred in the tunnel, and an example of the case where a fire has occurred in the upstream tunnel 1a For

  In this embodiment, when the disaster prevention control panel 10 detects a fire, the guidance display of the plurality of dynamic guidance display devices 14 arranged along the tunnel side wall is sequentially moved in a direction away from the fire place. Control to display the guidance direction.

  The disaster prevention receiving board 10 calculates the group number N of the guidance group from the address A of the dynamic guidance display device 14 arranged in the tunnel and performs guidance display control of the dynamic guidance display device 14. For this reason, addresses A = 1 to 15 are set in advance so as to increase from the left tunnel entrance 92 toward the right tunnel exit 94 in, for example, 15 dynamic guidance display devices 14 arranged in a staggered manner on both sides of the tunnel side wall. doing.

  The disaster prevention receiving board 10 has an initial setting associated with the start-up of the equipment. From the address A = 1 to 15 of the 15 dynamic guidance display devices 14, if a predetermined number of groups G, for example G = 5, is set to 5 The group number N of the guidance group to which the devices that belong to each other belong is calculated and set to each of the dynamic guidance display devices 14 by transmitting a group number setting message.

  If a fire has occurred in the tunnel during the operation after such initial setting, the disaster prevention receiver 10 detects the fire place 90 based on the fire signal from the fire detector installed in the tunnel, Since the address A of the dynamic guidance display device 14 closest to the fire place 90 is A = 7, the fire place address Af is detected as Af = 7.

  Subsequently, when the address A of the dynamic guidance display device 14 is equal to or greater than the fire place address Af, the disaster prevention receiving board 10 sets the address A of the dynamic guidance display device 14 to mod (G ) Is calculated as the group number N.

That is,
N = (A) mod (G) (Formula 1)
To obtain the group number N. The right side of (Equation 1) is known as a remainder calculation, which means the calculation of the remainder when address A is divided by the number of groups G.

  Here, since the fire place address Af = 7, the group numbers N = 2, 3, 4, 0, 1, 2, 3, 4, 0 are calculated. In this case, the group number N repeatedly changes so as to increase toward the tunnel exit 84 on the right side.

In addition, when the address A of the dynamic guidance display device 14 is less than the fire place address Af, the disaster prevention receiving board 10 multiplies the value obtained by mod (G) of the address A by (−1), and further (G− The group number N is obtained as a value obtained by adding 1). That is,
N = (A) mod (G) · (−1) + (G−1) (Formula 2)
To calculate the group number N.

  Here, since the fire place address Af = 7, the group number N = 3, 2, 1, 0, from the above (Formula 2) for the dynamic guidance display device 14 of the address A = 1 to 6 less than that. 4 and 3 are calculated. In this case, the group number N is a reverse setting that repeatedly changes so as to increase toward the tunnel entrance 82.

  As described above, the group number N calculated based on the addresses A = 1 to 15 and the fire place address Af = 7 is transmitted from the disaster prevention receiving board 10 to the group number setting message in which each device address is specified. Set for each of the guidance display devices 14. Subsequently, the disaster prevention receiving board 10 starts transmitting a control signal every predetermined period T.

  When determining that the control signal is received, the dynamic guidance display device 14 counts the number of receptions C, generates a guidance pattern number P (= C-1) as a value obtained by subtracting 1 from the number of receptions C, and guide pattern number P And the group number N are discriminated, a guidance display is performed. If a discrepancy is discriminated, the guidance display is not performed.

  For this reason, the guidance display of the black circle with the guidance pattern number P = 0 to 4 changing at the time t on the vertical axis is the guidance direction in which the right side of the fire place 90 sequentially moves toward the tunnel exit 94 as time t elapses. On the other hand, on the left side of the fire place 90, a guidance direction 96a that is a reverse direction that sequentially moves toward the opposite tunnel entrance 82 is displayed.

  FIG. 10 is a flowchart showing the control operation of the dynamic guidance display device that moves the guidance display in a direction away from the fire place by transmitting a control signal from the disaster prevention receiving board.

  As shown in FIG. 10, first, in step S1, the number of groups G, for example, G = 5 and the group number N for performing the guidance display are stored in the dynamic guidance display device 14. Here, the group number G is stored in advance in the dynamic guidance display device 14. On the other hand, since the group number N varies depending on the fire place in the tunnel, when a fire is detected, a set message including the group number N is transmitted from the disaster prevention receiving board 10 and stored.

  For example, when a fire occurs at the fire place 90 shown in FIG. 15, the disaster prevention receiving board 10 calculates the group number N according to the above (formula 1) and (formula 2) based on the fire place address Af = 7, and the setting message And stored in the dynamic guidance display device 14. The disaster prevention receiving board 10 that has transmitted a setting message for storing such a group number then starts transmitting a control signal every light emission period T.

  When the dynamic guidance display device 14 determines reception of the control signal in step S2, the dynamic guidance display device 14 proceeds to step S3 and counts the number of receptions C. The number of receptions C is set to C = 0 in the initial state. Then, it progresses to step S4 and the induction | guidance | derivation pattern number P (= C-1) is produced | generated as a value which subtracted 1 from the frequency | count C of reception.

  Next, it progresses to step S5 and it is discriminate | determined whether the guidance pattern number P corresponds with the group number N memorize | stored at step S1. If it is determined in step S5 that the light emission pattern number P matches the group number N, the process proceeds to step S6 to perform guidance display. On the other hand, if it is determined in step S5 that the light emission pattern number P does not match the group number N, step S6 is skipped and no guidance display is performed.

  Subsequently, in step S7, it is determined whether or not the number of receptions C matches the number of groups G. If they do not match, the process returns to step S2 to prepare for reception of the next control signal. On the other hand, if the number of receptions C matches the number of groups G in step S7, the number of receptions C is initialized to C = 0 in step S8 and the process returns to step S2 to prepare for reception of the next control signal. Thereafter, the processing in steps S2 to S8 is repeated in the same manner.

  In addition, about the group number memorize | stored in the dynamic induction | guidance | derivation display apparatus 14 by the disaster prevention receiving board 10, in addition to calculating and memorizing from said (Formula 1) and (Formula 2) when a fire breaks out, fire place address Af = Calculated from (Equation 1) and (Equation 2) every 1 to 15 and stored as table information, and the group number corresponding to the fire location address Af detected when a fire broke out is read from the table information May be stored in the dynamic guidance display device 14.

  Further, when the display of the plurality of dynamic guidance display devices 14 is continuously moved from the fire place to the tunnel entrance and is repeated, the group number G may be set to the maximum address A = 15 or more.

Further, when the display of the plurality of dynamic guidance display devices 14 is continuously moved from the fire place to the tunnel entrance / exit, each dynamic guidance display device 14 is other than the movement display by sequentially lighting the plurality of movement display marks. In addition, by simultaneously lighting a plurality of moving display marks, the display brightness may be increased by flashing light.
