Description

  The present invention relates to a disaster prevention system.

  Conventionally, an evacuation guidance system that performs evacuation guidance in the event of a fire has been known (see, for example, Patent Document 1). In this evacuation guidance system, for example, a plurality of flash devices are provided on the ceiling of a passage in a building, and the flash devices are caused to emit light, whereby evacuation is guided by light from the flash device.

JP 2017-27610 A

  However, in general, when smoke flows in when a fire breaks out, the smoke concentration rises from the ceiling side. There was a possibility that the disaster prevention performance would decrease. Also, when evacuation guidance is performed using an emergency light or evacuation guide light that is a device other than the flash device, or when the interior of the building is illuminated brightly by ceiling lighting, it is the same as the case of the flash device, that is, When the smoke is full, it may be difficult to visually recognize the emergency light or the evacuation guide light, or it may not be brightly illuminated by the ceiling lighting, and the disaster prevention property may be reduced.

  For this reason, there was room for improvement in terms of improving disaster prevention.

  This invention is made | formed in view of the said problem, and it aims at providing the disaster prevention system which can improve disaster prevention property.

  In order to solve the above-described problems and achieve the object, the disaster prevention system according to claim 1 is a disaster prevention system that performs disaster prevention in a target area, and outputs infrared light for displaying disaster prevention information. Infrared light output means and conversion means to which the infrared light output from the infrared light output means is irradiated, wherein the disaster prevention information is converted by converting the irradiated infrared light into visible light. And the conversion means for displaying in a visible manner.

  Moreover, the disaster prevention system according to claim 2 is the disaster prevention system according to claim 1, wherein the conversion means displays information on evacuation in the target area or information on disaster prevention equipment in the target area as the disaster prevention information. To do.

  Further, the disaster prevention system according to claim 3 is the disaster prevention system according to claim 1 or 2, based on the acquisition means for acquiring the smoke concentration of the target area, and the smoke concentration acquired by the acquisition means. Adjusting means for adjusting the infrared light output by the infrared light output means.

  Moreover, the disaster prevention system according to claim 4 is provided with a detection means for detecting the smoke concentration in the target area in the disaster prevention system according to claim 3, wherein the acquisition means detects the smoke detected by the detection means. The at least detection means, the acquisition means, the adjustment means, and the infrared light output means are integrally formed with each other.

  According to the disaster prevention system of claim 1, infrared light is output by the infrared light output means, and the infrared light output by the infrared light output means is converted by the conversion means so that the disaster prevention information can be visually recognized. For example, even if smoke is filled in the vicinity of the ceiling, the transmittance of infrared light to the smoke is higher than the transmittance of visible light from conventional flash devices, emergency lights, evacuation guide lights, or ceiling lighting. Since it is high, disaster prevention information can be displayed reliably, and disaster prevention can be improved. Further, for example, by providing the conversion means at a relatively low position, the smoke rises even when smoke flows in, so that the visibility of the disaster prevention information displayed on the conversion means can be ensured.

  According to the disaster prevention system according to claim 2, by displaying information on evacuation in the target area or information on the disaster prevention equipment in the target area as disaster prevention information, for example, evacuating appropriately and quickly, or disaster prevention equipment Since it can be handled appropriately and extinguish fire, it is possible to further improve the disaster prevention.

  According to the disaster prevention system according to claim 3, by adjusting the infrared light output by the infrared light output means based on the smoke concentration acquired by the acquisition means, for example, red depending on the smoke concentration Since the intensity of external light can be adjusted, the visibility of disaster prevention information can be maintained. In particular, for example, when the smoke concentration increases, the visibility of the disaster prevention information can be prevented from decreasing by increasing the intensity of infrared light, and the visibility of the disaster prevention information can be maintained. It becomes possible.

  According to the disaster prevention system according to claim 4, at least the detection means, the acquisition means, the adjustment means, and the infrared light output means are configured integrally with each other, for example, the detection means, Since the disaster prevention system can be configured by one unit including the acquisition means, the adjustment means, and the infrared light output means, and the conversion means, a wired communication means (for example, a predetermined distance (1 m between the units) ~ 3m etc.) communication line etc.) and wireless communication means (for example, wireless communication circuit etc.) become unnecessary, and it becomes possible to simplify the configuration of the disaster prevention system. In addition, for example, the detection unit, the acquisition unit, the adjustment unit, and the infrared light output unit can be configured as one unit, so that the disaster prevention system can be easily constructed.

It is a perspective view which shows the hallway of the building in which the conversion panel and infrared light output device which concern on this Embodiment were installed. It is a block diagram of a control apparatus. It is a flowchart of a display process. It is an example of the disaster prevention information displayed on a conversion panel.

Moreover, although this conversion panel 1 can be provided in arbitrary positions, such as the floor 41 of a building, the wall 42, or the ceiling 43, for example, here, arbitrary methods (for example, an adhesive agent or a screw | thread etc. are used for the wall 42). , Etc.). Since the conversion panel 1 is provided on the wall 42, for example, the conversion panel 1 can be prevented from being damaged by being stepped on by a user in the monitoring area, which is the target area. It becomes possible to plan.

(Configuration-Infrared light output device)
The infrared light output device 2 of FIG. 1 constitutes the display system 100 and is the above-described infrared light output means. The specific type and configuration of the infrared light output device 2 is arbitrary, but for example, any means (for example, wired connection by wiring, or so as to enable communication with the control device 3 of FIG. 2 or In addition, the infrared light is output from the output port 21 of FIG. 1 toward the conversion panel 1 under the control of the control device 3. In addition, the infrared light output device 2 can be configured using, for example, one or more infrared light sources that output infrared light as laser light in order to display disaster prevention information on the conversion panel 1.

(Configuration-control device)
The control device 3 in FIG. 2 constitutes the display system 100 and is device control means for controlling the infrared light output device 2. The specific type and configuration of the control device 3 are arbitrary, but for example, any means (for example, wired connection by wiring, or so as to enable communication with the infrared light output device 2 of FIG. 1 or , Wireless connection using radio waves, etc.) and provided in a management room (not shown) of the building of FIG. 1, and the communication unit 31 and the recording unit 32 shown in FIG. , And a control unit 33.

(Configuration-Control device-Communication unit)
The communication unit 31 is a communication unit that communicates with an external device (for example, the infrared light output device 2 or a disaster prevention receiver (not shown)). Although the specific kind and structure of this communication part 31 are arbitrary, it can comprise using a well-known communication circuit etc., for example.

(Configuration-Control device-Recording unit)
The recording unit 32 is a recording unit that records a program and various data necessary for the operation of the control device 3, and is configured using, for example, an EEPROM or a flash memory. However, instead of EEPROM or Flash memory, or together with EEPROM or Flash memory, an external recording device such as a hard disk, a magnetic recording medium such as a magnetic disk, an optical recording medium such as a DVD or a Blu-ray disc, or a ROM, USB memory, SD Any other recording medium can be used, including an electrical recording medium such as a card.

(Configuration-Control device-Control unit)
The control unit 33 is a control unit that controls the control device 3. Specifically, the CPU, various programs interpreted and executed on the CPU (a basic control program such as an OS, and a specific function that is activated on the OS, And an internal memory such as a RAM for storing the program and various data. In particular, the control program according to the embodiment substantially configures each unit of the control unit 33 by being installed in the control device 3 via an arbitrary recording medium or network. The processing performed by each unit of the control unit 33 will be described later.

(processing)
Next, the display process configured as described above and executed by the control device 3 will be described. FIG. 3 is a flowchart of the display process (in the following description of each process, step is abbreviated as “S”). FIG. 4 is an example of disaster prevention information displayed on the conversion panel. The “display process” is a process for displaying disaster prevention information on the conversion panel 1. The timing for executing this display process is arbitrary. For example, when the power of the control device 3 is turned on, it is assumed that the execution starts and is repeatedly executed.

  In SA1 of FIG. 3, the control unit 33 of the control device 3 determines whether or not to output infrared light. Specifically, for example, when a fire is determined by an arbitrary method (for example, pressing the determination button after the fire detector has triggered the alarm) on the disaster prevention receiver (not shown), the disaster prevention receiver Is configured to transmit a fire determination signal to the control device 3, and the following processing is performed. Specifically, when the fire determination signal is not received via the communication unit 31, the control unit 33 in FIG. 4 determines that no fire is generated and that no infrared light is output (NO in SA1). ) SA1 is repeatedly executed until it is determined that infrared light is output. When a fire determination signal is received via the communication unit 31, it is determined that a fire has occurred and infrared light is output (YES in SA1), and the process proceeds to SA2. Here, for example, when a fire is determined on the disaster prevention receiver (not shown), a fire determination signal is transmitted to the control device 3, and the control device 3 receives the fire determination signal. Yes, it is determined that infrared light is output.

  In SA2 of FIG. 3, the control unit 33 of the control device 3 starts outputting infrared light. Specifically, for example, the infrared light output device 2 in FIG. 1 is accessed, and the output of infrared light from the infrared light output device 2 is started. Although the output mode of infrared light is arbitrary, for example, the infrared light from the infrared light output device 2 is irradiated on the conversion panel 1 and the red light irradiated by the upconversion phosphor material of the conversion panel 1 is irradiated. By converting external light into visible light, infrared light is output as laser light so that the character information 11 and the image information 12 can be viewed as shown in FIG. The character information 11 and the image information 12 are disaster prevention information, specifically, information indicating the direction of the emergency exit. In particular, the character information 11 is text information of the characters “emergency exit”, and the image information 12 Is image information of a plurality of arrows indicating the right direction in FIG. Here, for example, the control unit 33 of the control device 3 continuously displays the characters “emergency exit” which is the character information 11, and the plurality of arrows of the image information 12 are changed from the left side to the right side in FIG. 4. In order to give a flowing image, the infrared light output from the infrared light output device 2 is started so that display and non-display of the plurality of arrows are sequentially repeated.

  When processing is performed in this way, for example, the user can recognize the direction in which he / she should evacuate by visually recognizing the character information 11 and the image information 12 in FIG. It becomes possible. Further, for example, in any case including a case where the fire is directly under the floor shown in FIG. 1, fire smoke also flows into the corridor 400 of FIG. 1, and near the ceiling 43 (that is, the infrared light output device 2 The smoke concentration increases from the surroundings of the light source, but even if smoke flows between the conversion panel 1 and the infrared light output device 2, the light output from the infrared light output device 2 is red. Since it is external light, the inflowing part is transmitted with a relatively high transmittance and is irradiated to the conversion panel 1. Therefore, even if smoke flows in, it is possible to reliably display the character information 11 and the image information 12 in FIG.

  In SA3 of FIG. 3, the control unit 33 of the control device 3 determines whether or not to end the output of infrared light. Specifically, for example, when a recovery operation is performed on a disaster prevention receiver (not shown), the recovery signal is transmitted to the control device 3 as follows. To process. Specifically, when the recovery signal is not received via the communication unit 31, the control unit 33 determines that the fire is not extinguished and determines that the infrared light output is not terminated (SA3). NO), SA3 is repeatedly executed until it is determined that the output of infrared light is finished. If a recovery signal is received via the communication unit 31, it is determined that the fire has been extinguished, it is determined that the output of infrared light is to be terminated (YES in SA3), and the process proceeds to SA4. Here, for example, when a recovery operation is performed on the disaster prevention receiver (not shown), a recovery signal is transmitted, but since the control device 3 receives this recovery signal, it is determined that the fire has been extinguished, It is determined that the output of infrared light is finished.

  In SA4 of FIG. 3, the control unit 33 of the control device 3 ends the output of infrared light. Specifically, for example, the infrared light output device 2 in FIG. 1 is accessed, and the output of infrared light from the infrared light output device 2 is terminated. When processing is performed in this manner, the character information 11 and the image information 12 of the conversion panel 1 shown in FIG. 4 disappear. This ends the display process.

(Effect of embodiment)
As described above, according to the present embodiment, the infrared light output device 2 outputs infrared light, and the infrared light output from the infrared light output device 2 is converted by the conversion panel 1 to provide disaster prevention information. By making it visible, for example, even if smoke is filled in the vicinity of the ceiling, the transmittance of infrared light to smoke is the transmittance of visible light from conventional flash devices, emergency lights, evacuation guide lights, or ceiling lighting. Therefore, it is possible to display disaster prevention information with certainty and improve disaster prevention. In addition, for example, by providing the conversion panel 1 at a relatively low position, the smoke rises even when smoke flows in, and thus it is possible to ensure the visibility of the disaster prevention information displayed on the conversion panel 1.

Moreover, in the said embodiment, since the information is displayed on the conversion panel 1 with the infrared light from the infrared light output device 2, the information displayed on the conversion panel 1 can be changed arbitrarily. Focusing on a certain point, you may comprise as follows. For example, the control device 3 acquires arbitrary information held by the disaster prevention receiver from the disaster prevention receiver, and based on the acquired information, arbitrary information (for example, information that identifies the fire floor or the fire position). You may display as disaster prevention information. For example, when a fire breaks out on the floor shown in FIG. 1, an image of an arrow indicating a direction away from the fire position may be displayed as disaster prevention information.

(About disaster prevention information (3))
In the above embodiment, information may be displayed on the conversion panel 1 not only when a fire occurs but also when no fire occurs. For example, infrared light may be output even when no fire occurs, and disaster prevention information may be displayed on the conversion panel 1 at all times. Further, for example, information other than the disaster prevention information (for example, advertisement information) may be displayed when no fire occurs, and may be switched to the disaster prevention information when a fire occurs.

Text information such as “The fire door is closed. Pull it open” may be displayed as disaster prevention information.

(About the conversion panel)
Moreover, although the said embodiment demonstrated the case where disaster prevention information was displayed using the conversion panel 1 in which the whole surface was formed with the upconversion fluorescent material, it is not restricted to this, Upconversion fluorescent substance on a panel etc. After the disaster prevention information is described in the material, it is displayed by radiating infrared light to the entire panel by infrared light output means such as the infrared light output device 2 to reveal the described disaster prevention information. May be. When comprised in this way, it becomes possible to always display the disaster prevention information of the same content.

  Moreover, although the case where the conversion panel 1 was provided in the wall 42 was demonstrated in the said embodiment, you may provide not only in this but in the floor 41 of a building. When comprised in this way, the distance of the smoke layer which passes is smaller than irradiating diagonally toward a wall surface, and it becomes possible to display disaster prevention information more clearly.

The acquisition unit acquires the smoke concentration detected by the detection unit, and the adjustment unit outputs the infrared light output unit based on the smoke concentration acquired by the acquisition unit. You may comprise so that infrared light may be adjusted. Although the infrared light adjustment method here is arbitrary, for example, in order to maintain the visibility of disaster prevention information, focusing on the fact that the amount of transmitted infrared light decreases as the smoke concentration increases, You may adjust so that the intensity | strength of the infrared light which an infrared light output part outputs may rise as the density | concentration of the smoke which the detection part detected rises. Specifically, table information and an arithmetic expression indicating the relationship between smoke concentration and infrared light intensity are recorded in the recording unit 32, and the acquisition unit Communication is performed to acquire the smoke concentration from the detection unit, and when the acquisition unit acquires the smoke concentration, the adjustment unit acquires the smoke concentration by referring to the table information or the arithmetic expression recorded in the recording unit 32. The infrared light intensity corresponding to the smoke concentration acquired by the unit is specified, the infrared light output device 2 is controlled, and the infrared light having the specified intensity is output from the infrared light output device 2.

(Additional effects)
According to the disaster prevention system described in Appendix 1, infrared light is output by the infrared light output means, and the infrared light output by the infrared light output means is converted by the conversion means so that the disaster prevention information can be visually recognized. For example, even if smoke is filled near the ceiling, the transmittance of infrared light to smoke is higher than the transmittance of visible light from conventional flash devices, emergency lights, evacuation guide lights, or ceiling lighting. Therefore, disaster prevention information can be displayed reliably and disaster prevention can be improved. Further, for example, by providing the conversion means at a relatively low position, the smoke rises even when smoke flows in, so that the visibility of the disaster prevention information displayed on the conversion means can be ensured.

  According to the disaster prevention system described in appendix 2, by displaying information on evacuation in the target area or information on the disaster prevention equipment in the target area as disaster prevention information, for example, evacuate appropriately and quickly, or Since it can be handled properly and extinguished, it is possible to further improve disaster prevention.

  According to the disaster prevention system described in the supplementary note 3, by adjusting the infrared light output by the infrared light output unit based on the smoke concentration acquired by the acquisition unit, for example, infrared depending on the smoke concentration Since the intensity of light can be adjusted, the visibility of disaster prevention information can be maintained. In particular, for example, when the smoke concentration increases, the visibility of the disaster prevention information can be prevented from decreasing by increasing the intensity of infrared light, and the visibility of the disaster prevention information can be maintained. It becomes possible.

  According to the disaster prevention system described in appendix 4, at least the detection means, the acquisition means, the adjustment means, and the infrared light output means are configured integrally with each other. Since the disaster prevention system can be configured by one unit including the means, the adjusting means, the infrared light output means, and the conversion means, the wired communication means (for example, a predetermined distance (1 m to 3m or the like) or wireless communication means (for example, a wireless communication circuit) becomes unnecessary, and the configuration of the disaster prevention system can be simplified. In addition, for example, the detection unit, the acquisition unit, the adjustment unit, and the infrared light output unit can be configured as one unit, so that the disaster prevention system can be easily constructed.
