Description

  The present invention relates to a tunnel alarm system.

  As an alarm means for alarming an abnormality such as an accident in a tunnel, an alarm display plate installed at a tunnel well or inside is known. However, the warning sign board installed at the tunnel entrance cannot alert the driver, pedestrian, etc. (hereinafter referred to as “user”) inside the tunnel, and the warning sign board installed inside the tunnel is It is not installed depending on the tunnel specifications such as the length. As described above, the alarm display board alone is not sufficient as means for notifying the abnormality in the tunnel.

  2. Description of the Related Art As an apparatus that issues an alarm throughout a tunnel, an apparatus that alerts an abnormality using a red indicator lamp installed at regular intervals in the tunnel is known. When the push button in the tunnel is pressed, the red indicator light is flickered, and a warning is transmitted to users throughout the tunnel. However, the user cannot recognize how to deal with the abnormality only by flickering the red indicator lamp. For example, even a reporter who has pressed the push button cannot know how to deal with the abnormality.

  As an apparatus for guiding a user to cope with an abnormality in a tunnel, Patent Document 1 discloses an in-tunnel display apparatus in which an instruction unit including a left and right arrow and a distance and a guidance mark are displayed in an electrical display. This tunnel display device guides evacuation by turning on an arrow in a direction that is safe and advantageous, and turning off the other when an abnormality such as a fire occurs. Specifically, a signal from the abnormality occurrence detection unit in the tunnel is sent to the electric room, and lighting and extinguishing of the lightning type sign are controlled in the electric room.

However, the conventional tunnel alarm device as disclosed in Patent Document 1 has the following problems.
First, the conventional tunnel alarm device has a problem that it lacks versatility. Conventional display displays are fixed. Considering the length of the tunnel, the location of emergency exits, etc., and various types of display devices are individually manufactured according to the installation position in the same tunnel. Need to be done. Therefore, ensuring the versatility of each component device of the tunnel alarm system is an issue.

  Secondly, the conventional tunnel alarm device has a problem of lack of infrastructure. In the conventional apparatus, each abnormality occurrence detection unit and each lightning type sign must be comprehensively connected by a contact-type circuit. Therefore, in a long tunnel, the scale of the infrastructure increases as the number of connected display devices increases. It will become something. Therefore, improvement of infrastructure is an issue when introducing a tunnel warning system.

  Third, the conventional tunnel alarm device has a problem of lack of information. As described above, the display is fixed in the electric display of the pointing portion and the guidance mark that are composed of the left and right arrows and distances, and various displays cannot be performed. For example, it is not possible to display an appropriate evacuation route when there are a plurality of evacuation routes (for example, wellheads and emergency exits) only by displaying the direction and distance of the exit. Further, it is not possible to guide an appropriate evacuation route according to the accident occurrence position, and display flexibility is lacking. For example, if there is an accident occurrence position between the current position and the exit on the side close to the current position, it may be better to guide the user to the exit on the far side rather than the exit on the side closer to the current position. is there. In relation to this, the above display cannot display detailed information such as where the accident occurred in the tunnel. For example, the urgency level of evacuation (the position where the accident occurred is the current position) If it is near, it is necessary to quickly condemn it. As described above, in the tunnel warning system, improvement of information in display is a problem.

The third alarm device may be configured to display and output an alarm based on alarm position information indicating the position of the own device in response to reception of the alarm signal. As a result, since the alarm signal is transmitted using the alarm device as a relay means, the alarm signal is reliably transmitted without being attenuated or lost even in a long tunnel. In addition, since a communication system for a relatively short distance can be adopted as the communication system, the degree of freedom in designing the alarm device is increased.

Embodiment 1. FIG.
FIG. 1 shows a schematic diagram of a tunnel alarm system 1 according to a first embodiment of the present invention. The tunnel alarm system 1 includes notification devices 2-1 to 2-n (n = 8 in the present embodiment) and alarm devices 3-1 to 3-n (n = 8 in the present embodiment) in the tunnel T. . The tunnel T has an entrance-side wellhead Ta and an exit-side wellhead Tb, and has an emergency exit E near the center of the tunnel. Moreover, the alarm display board 4 connected to the reporting apparatus 2-1 to 2-8 may be provided in the vicinity of the wellhead Ta. In the following description, the reporting devices 2-1 to 2-n are collectively referred to as the reporting device 2 or the reporting device 2-k as a representative of some of them. Similarly, the alarm devices 3-1 to 3-n are collectively referred to as the alarm device 3 or the alarm device 3-k on behalf of some of them.

  In this embodiment, for example, when the notification device 2-6 is activated, a notification signal activated by the notification device 2-6 is sent to the corresponding alarm device 3-6, and another alarm is issued from the alarm device 3-6. An alarm signal based on the notification signal is transmitted to the devices 3-1 to 3-5, 3-7 and 3-8. The report signal includes report position information that identifies the report device 2 (report device 2-6) that activated the report signal. Each alarm device 3 displays and outputs an alarm position information indicating the position of the own device and an alarm based on the notification position information.

  FIG. 2 shows a block diagram of the tunnel alarm system 1 of the present embodiment. As an outline, the reporting device 2 is a reporting device such as a contact type push button type reporting device or a fire detector, and the alarm device 3 is a display device. Notification devices 2-1 to 2-8 and alarm devices 3-1 to 3-8 are connected via lines L1-1 to L1-8, respectively. The alarm devices 3 are connected by a line L2. In the following description, the lines L1-1 to L1-n are collectively referred to as a line L1 or L1-k as a representative of some of them. That is, the reporting device 2-k and the alarm device 3-k are connected by the line L1-k.

  In the present embodiment, the notification device 2-k and the alarm device 3-k are preferably arranged at corresponding positions. Thereby, the total length of the lines L1-1 to L1-n can be minimized. In this specification, “the notification device 2-k and the alarm device 3-k are arranged at corresponding positions” means that the distance from the notification device 2-k to the alarm device 3-k is the notification device. The reporting device 2-k is shorter than any of the distance from the reporting device other than the reporting device 2-k and the distance from the reporting device other than the reporting device 2-k to the warning device 3-k. The alarm device 3-k is arranged. As an example of the “corresponding position”, there is an arrangement in which the alarm device 3-k is directly above the notification device 2-k.

  Each notification device 2 includes a push button 20 or a fire detection unit 21, a report activation unit 22, and an output unit 23. When the push button 20 is pressed by the user, the contact is opened or connected, and the notification activation unit 22 activates the notification signal accordingly. The fire detection unit 21 detects the flame and / or smoke at the time of the fire and outputs a detection signal, and the notification activation unit 22 activates the notification signal accordingly. When the reporting device 2 is a push button type reporting device, a push button 20 is provided. When the reporting device 2 is a fire detector, a fire detection unit 21 is provided, but both may be used together. Each reporting device 2 may be provided with a red indicator light that flickers when activated. At this time, all the red indicator lamps in the tunnel T may be flickered, or the red indicator lamps that have been notified may be flickered.

  The output unit 23 sends the notification signal activated by the notification activation unit 22 to the line L1. When the output unit 23 is a wired transmission unit (for example, contact type), the line L1 is a wired line (for example, circuit wiring), and when the output unit 23 is a wireless transmission unit, the line L1 is a wireless communication line. In this embodiment, it is assumed that each alarm device 3 is almost directly above each notification device 2, and the notification device 2 and the alarm device 3 in the upper and lower positions correspond to each other. A notification signal is sent to the device 3-k.

  Each alarm device 3 includes an input unit 30, a processing unit 31, a display unit 32, and a transmission / reception unit 33. As an outline, when a notification signal from the output unit 23 of the notification device 2 is input to the input unit 30 or an alarm signal from another alarm device 3 is received by the transmission / reception unit 33, the processing unit 31 An alarm based on the position information and the self-alarm device position information is generated and displayed on the display unit 32. The alarm devices 3 are connected to each other in a manner that enables wired communication or wireless communication.

  A notification signal from the output unit 23 of the notification device 2 is input to the input unit 30. The input unit 30 is an input circuit or a wired receiver when the line L1 is a contact-type wiring or a wired communication line, and a wireless receiver when the line L1 is a wireless communication line. The processing unit 31 generates an alarm based on the input or received notification signal and alarm signal, and causes the display unit 32 to display and output the alarm. Details of the processing unit 31 will be described later.

  The display unit 32 includes a liquid crystal display (LCD: Liquid Crystal Display) 320 (hereinafter referred to as “LCD 320”) as an image display unit, and further includes a speaker 321 as necessary. The LCD 320 displays an image of an alarm generated by an alarm generation unit 314 of the processing unit 31 described later as an image (character information, graphic information, a combination thereof, etc.), and the speaker 321 outputs the content of the alarm as a sound. Note that the speaker 321 may be omitted.

  The transmission / reception unit 33 transmits / receives an alarm signal to / from another alarm device 3. Various modes are possible as a communication method between the alarm devices 3. For example, each alarm device 3 can be configured to capture data corresponding to its own address among the data on the communication line L2. When the communication line L2 is a wired communication line, for example, TCP / IP, RS485, or the like can be used as a communication protocol. When the communication line L2 is a wireless communication line, for example, WiFi, ZigBee, or the like can be used as a communication protocol. However, the communication protocol is not limited to these.

  FIG. 3 shows a block diagram of the processing unit 31 and the display unit 32. The processing unit 31 includes an input / output interface (I / F) 310, a CPU 311, a storage unit 312, a notification position acquisition unit 313, an alarm generation unit 314, and an alarm signal generation unit 315, which are connected to each other by a bus 316. ing. The input / output interface 310 constitutes an interface with the input unit 30 and the transmission / reception unit 33, and the CPU 311 is a processor that controls the exchange of signals between the units.

  The storage unit 312 is a memory such as a RAM or ROM that stores programs, data, and the like. The storage unit 312 stores, as a reference table, the relationship between the acquired notification position information, the stored alarm position information, and the alarm to be generated. That is, the alarm is set based on the report position information and the alarm position information. For example, when the position indicated by the report position information (accident occurrence position) and the position indicated by the alarm position information are relatively close, the alarm to be set includes the evacuation direction, the shortest evacuation route, a message prompting quick evacuation, etc. Should be included. On the other hand, when the position indicated by the report position information (accident occurrence position) and the position indicated by the alarm position information are relatively far, the alarm to be set includes an evacuation direction, further entry suppression, a message to call attention, etc. Should be included.

  The notification position acquisition unit 313 extracts the notification position information from the notification signal when the notification signal is input from the input unit 30 and from the alarm signal when the alarm signal is received from the transmission / reception unit 33.

  The alarm generation unit 314 generates an alarm to be output by the alarm device 3 with reference to the storage unit 312 according to the acquisition of the report position information. That is, the alarm generation unit 314 determines the content of the alarm from the notification position information and the alarm position information indicating the position of the own alarm device. The details of the alarm will be described later.

  When a notification signal is input from the input unit 30, the alarm signal generation unit 315 converts the notification signal into an alarm signal in a communication format between the alarm devices 3. This alarm signal is transmitted from the transmission / reception unit 33 to another alarm device 3. For example, the alarm signal generation unit 315 generates an alarm signal including address data corresponding to the alarm position information of each of the other alarm devices 3 and data of the notification position information in a frame.

  With reference to FIG. 4, the alarm content in the tunnel alarm system 1 is demonstrated. FIG. 4 shows the contents of the alarm on the LCD 320 of each alarm device 3. In the example shown in FIG. 4, the vehicle traveling direction in the tunnel T is the right side of the figure (that is, the vehicle enters from the wellhead Ta and exits from the wellhead Tb), and the direction (place name) on the tunnel entry side is A. The direction (place name) on the traveling direction side is B. Note that illustration of each communication line is omitted. Here, a vehicle accident occurred between the reporting device 2-6 and the reporting device 2-7, and the reporting device 2-6 was activated by pressing the push button 20 by the user or detecting a fire by the fire detection unit 21. Shall.

  A notification signal including notification position information is sent from the notification device 2-6 to the alarm device 3-6. The alarm device 3-6 generates the alarm corresponding to the report position information and the alarm position information, and displays and outputs the alarm by the display unit 32. And alarm device 3-6 converts a report signal into an alarm signal, and transmits to other alarm devices 3-1 to 3-5, 3-7, and 3-8. Each alarm device 3 takes in a frame of an alarm signal that addresses itself and displays and outputs an alarm according to the alarm signal.

  For example, the LCD 320 of the alarm device 3-1 near the entrance side tunnel of the tunnel T displays and outputs an alarm “An accident occurred near the exit on the B side. Please evacuate outside the tunnel.” As a result, further entry of the user into the tunnel T where the accident has occurred is suppressed. The alarm device 3-2 may be configured to issue the same alarm as the alarm device 3-1. Here, the displayed character may be scrolled from right to left, for example, so that the size per character may be increased, or the number of characters may be increased.

  In addition, the alarm device 3-3 located near the middle of the wellhead Ta and the accident occurrence position performs a display indicating the positional relationship between the current position of the user and the accident occurrence position. Thereby, the user can determine the evacuation route after grasping the relationship between the current position and the accident occurrence position. Moreover, as shown in FIG. 5, you may make it display the evacuation direction together with a present position and an accident occurrence position as needed. Here, although there are two evacuation route options near the alarm device 3-3, the well exit Ta and the emergency exit E, it is desirable to guide the user away from the accident occurrence position. Therefore, the alarm device 3-3 displays evacuation in the direction of the mine entrance Ta instead of the emergency exit E by an arrow. As a result, the user can intuitively grasp the relationship between the user's own position, the accident occurrence position, and the evacuation route, and can calmly head toward the wellhead Ta.

  In the alarm device 3-6 close to the accident occurrence position, for example, the LCD 320 displays and outputs an alarm “Please evacuate immediately from the emergency exit” and the speaker 321 outputs a similar message by voice. As a result, users near the accident site can quickly evacuate from the emergency exit E. Note that the alarm devices 3-4 and 3-5 may be configured to perform the same alarm. In particular, there is a possibility that the user near the alarm device 3-5 may head toward the accident site aiming at the wellhead Tb when there is no indication. Can evacuate safely towards the emergency exit E in the opposite direction.

  The LCD 320 of the alarm devices 3-7 and 3-8 on the wellhead Tb side from the accident occurrence position displays and outputs an alarm such as “Accident occurs at the rear. Alternatively, nothing may be displayed on the alarm devices 3-7 and 3-8. In this way, the user (driver) who is closer to the traveling direction than the position where the accident occurred is guided to move forward as it is and exit from the wellhead Tb.

  Note that the image display on the LCD 320 of the alarm device 3 may be a still image or a moving image, and the information property is further enhanced by using the moving image. In addition to the display output in the alarm, a message “Accident in tunnel” may be displayed on the alarm display plate 4 outside the wellhead Ta side to prevent the vehicle from entering.

  As described above, according to the tunnel alarm system 1 of the present embodiment, the following advantageous effects can be obtained. The following advantageous effects become prominent when a plurality of notification devices 2 are installed, but can also be enjoyed when only one notification device 2 is installed.

(1) Improvement of versatility In the tunnel alarm system 1 in which a plurality of alarm devices 3 are installed, the hardware configuration of each alarm device 3 can be configured with substantially the same specifications, and a highly versatile tunnel alarm. A system can be constructed.

(2) Improvement of infrastructure In the tunnel alarm system 1 having the notification device 2 and the plurality of alarm devices 3, the notification signal is input / output between the corresponding notification device 2 and the alarm device 3, and the alarm signal is transmitted between the alarm devices 3. Is transmitted. Therefore, signal wiring between the reporting devices 2 is not required, and a tunnel infrastructure system with a high infrastructure property can be realized with a simple configuration.

(3) Improvement of information (accuracy) An alarm for each of the alarm devices 3 is determined based on the report position information and the alarm position information. Therefore, the effect that the detailed situation in the tunnel can be conveyed to the user can be obtained. In addition, since the display contents can be flexibly changed according to the reporting position close to the accident occurrence position, a tunnel warning system with high display information and accuracy can be realized.

(4) Improvement of information (intuition) The LCD 320 uses character information, graphic information, etc. to determine the position of the accident (the position indicated by the report position information), the current position (the position indicated by the alarm position information), and the evacuation route as necessary. Since the alarm display including “” is performed, the abnormality in the tunnel can be transmitted to the user with high information property. Thus, since the information property and intuition of display are further improved, the user can grasp the situation in the tunnel more clearly and intuitively, and a secondary disaster due to lack of information is effectively prevented.

<Modification 1 of Embodiment 1>
In the above embodiment, the configuration in which the alarm is determined based on the notification position information and the alarm position information is shown. However, in the present modification, a configuration in which the alarm is determined based only on the alarm position information is shown. A schematic configuration diagram of the tunnel alarm system 1 according to this modification is the same as that of FIG. 1, and its block diagram is the same as that of FIG. However, the processing unit 31 of this modification does not include the reporting position acquisition unit 313 in FIG. Hereinafter, only the differences from the above embodiment will be described in the present modification.

  In this modification, the notification signal output from the output unit 23 of the notification device 2 to the input unit 30 of the alarm device 3 includes a signal indicating that the notification signal has been activated (that is, an accident has occurred). The report location information is not included. Therefore, each alarm device 3 displays and outputs an alarm based on the alarm position information indicating the position of the own device when the notification signal is input.

  The storage unit 312 stores the relationship between the stored alarm position information and the alarm to be generated as a reference table. For example, an alarm for preventing the vehicle from entering may be set for an alarm device (for example, the alarm devices 3-1 and 3-2) in the vicinity of the tunnel entrance side wellhead Ta. Moreover, what is necessary is just to make it set the alarm for guiding a user to the emergency exit E with respect to the alarm devices (for example, alarm devices 3-3 to 3-6) near the emergency exit E. In addition, for the alarm device (for example, the alarm devices 3-7 and 3-8) in the vicinity of the tunnel exit-side wellhead Tb, an alarm is set to prompt the user to move forward and exit the tunnel. You can do it. Or, for alarm devices near the tunnel center (for example, alarm devices 3-3 to 3-6), the current position (the position of each alarm device) and the evacuation route (guidance to the entrance or the nearest emergency exit) are shown. An alarm may be set.

  The alarm generation unit 314 determines an alarm to be output by the alarm device 3 with reference to the storage unit 312 in response to input or reception of a notification signal or an alarm signal. That is, the alarm generation unit 314 determines an alarm for the own alarm device 3 from the alarm position information that is the position information of the own alarm device.

  Also according to this modification, the above advantageous effects (1) improvement in versatility, (2) improvement in infrastructure, and (4) improvement in information (intuition) can be obtained, and the position of each alarm device 3 Since the alarm contents can be changed by signal processing according to the situation, various information can be alarmed, and the information property (accuracy) of the tunnel alarm system is ensured.

<Modification 2 of Embodiment 1>

  As shown in FIGS. 6 and 7, adjacent alarm devices 3 are connected to each other, and each alarm device 3 (transmission / reception unit 33 ′) serves as a relay, and an alarm signal is communicated between the adjacent alarm devices 3. The communication line L2 ′ in this case can be configured in the same manner as the communication line L2, but a communication method for a relatively short distance can be adopted, or when adjacent alarm devices 3 can be seen through, an LED unit or the like can be used. Visible light communication can also be employed. Visible light communication should just be based on standards, such as IEEE802.15.7, IrDA / VLCC, JEITA CP-1221, CP1222. When each alarm device 3 is a repeater, the transmission / reception unit 33 ′ has waveform reshaping means, so that attenuation or disappearance of the transmitted alarm signal can be suppressed. As a result, the alarm signal can be reliably transmitted without being attenuated or lost even in a long tunnel, and a communication method for a relatively short distance (for example, about 50 m to 100 m) can be adopted as a communication method. The degree of freedom in designing the device 3 is increased.

  In this embodiment, when the sub notification device 2S (notification device 2-6) is activated, a notification signal activated by the sub notification device 2S is output to the main notification device 2M (notification device 2-5), and the main It is output from the reporting device 2M to the master alarm device 3M (alarm device 3-5). Then, an alarm signal based on the notification signal is transmitted from the master alarm device 3M to each slave alarm device 3S. The report signal includes report position information that identifies the report device 2 (report device 2-6) that activated the report signal. Each of the alarm devices 3M and 3S displays and outputs alarm position information indicating the position of the own device and an alarm based on the notification position information, as in the first embodiment.

  FIG. 9 shows a block diagram of the tunnel alarm system 1 of FIG. The sub notification device 2S and the main notification device 2M are connected via a line L0, and the main notification device 2M and the master alarm device 3M are connected via a line L1. The line L0 may be a wired line (including contact-type circuit wiring) or a wireless communication line. The master alarm device 3M is preferably almost directly above the main notification device 2M. Thereby, the line L1 can be minimized.

  The sub notification device 2S includes a push button 20 or a fire detection unit 21, a notification activation unit 22, and an output unit 23S. The output unit 23S outputs the report signal activated by the report activation unit 22 to the main notification device 2M via the line L0.

  The main notification device 2M includes a push button 20 or a fire detection unit 21, a notification activation unit 22, a transmission unit 23M, and an input unit 24M. A notification signal from the sub notification device 2S is input to the input unit 24M via the line L0. The output unit 23M sends the notification signal input to the input unit 24M or the notification signal activated by the notification activation unit 22 of the main notification device 2M to the line L1.

  The master alarm device 3M includes an input unit 30, a processing unit 31M, a display unit 32, and a transmission unit 33M. When a notification signal is input to the input unit 30, the processing unit 31 </ b> M generates an alarm based on the notification position information and the alarm position information and outputs the alarm to the display unit 32. As in the first embodiment, the display unit 32 displays and outputs the alarm generated by the processing unit 31M using the LCD 320 or the like.

  The processing unit 31M also transmits an alarm signal based on the notification signal from the transmission unit 33M to the slave alarm device 3S. Communication from the master alarm device 3M to the slave alarm device 3S may be via wired connection or wireless connection. Here, the alarm signal may include notification position information, or alarm information (alarm information) to be output by each slave alarm device 3S.

  The slave alarm device 3S includes a processing unit 31S, a display unit 32, and a receiving unit 33S. The receiving unit 33S takes in a frame having its own address data from the communication line L2 as an alarm signal. Based on the alarm signal received from the master alarm device 3 via the receiver 33S, the processing unit 31S generates an alarm based on the notification position information and the alarm position information, or an alarm based on the alarm information. As in the first embodiment, the display unit 32 displays and outputs the alarm generated by the processing unit 31S using the LCD 320 or the like.

  FIG. 10A shows an example of a block diagram of the processing unit 31M of the master alarm device 3M and the processing unit 31S of the slave alarm device 3S. FIG. 10A shows a configuration in the case where report position information is included in the alarm signal.

  The processing unit 31M of the master alarm device 3M includes an input / output interface (I / F) 310, a CPU 311, a storage unit 312, a notification position acquisition unit 313M, an alarm generation unit 314, and an alarm signal generation unit 315, which are bus 316. Are connected to each other.

  The reporting position acquisition unit 313M extracts reporting position information from the reporting signal input by the input unit 30. The notification signal is converted into an alarm signal according to a predetermined communication format by the alarm signal generation unit 315. For example, the alarm signal includes a frame of address data and alarm information data corresponding to the alarm position information of each slave alarm device 3S, and this is transmitted from the transmitter 33M to the slave alarm device 3S. As a communication method to the slave alarm device 3S, various wired communication or wireless communication described in the first embodiment is applied.

  The processing unit 31S of the slave alarm device 3S includes an input / output interface (I / F) 310, a CPU 311, a storage unit 312, a notification position acquisition unit 313S, and an alarm generation unit 314, which are connected to each other by a bus 316. Yes.

  The reporting position acquisition unit 313S extracts reporting position information from the alarm signal captured by the receiving unit 33S. Thereby, the alarm generation unit 314 can generate an alarm based on the notification position information and the alarm position information that is the own apparatus position information stored in the storage unit 312.

  FIG. 10B shows another example of a block diagram of the processing unit 31M of the master alarm device 3M and the processing unit 31S of the slave alarm device 3S. FIG. 10B shows a configuration when the alarm information does not include the notification position information but includes alarm information (alarm information) to be output by each slave alarm device 3S.

  The processing unit 31M of the master alarm device 3M includes an input / output interface (I / F) 310, a CPU 311, a storage unit 312M, a notification position acquisition unit 313M, an alarm generation unit 314, and an alarm signal generation unit 315M, which are buses 316. Are connected to each other.

  The storage unit 312M stores, as a reference table, a relationship between alarm position information indicating the position of each slave alarm device 3S and an alarm (alarm information) to be output by each slave alarm device 3S. For example, an alarm for preventing the vehicle from entering may be set for a slave alarm device (for example, alarm devices 3-1 and 3-2) near the tunnel entrance side wellhead Ta. Moreover, what is necessary is just to make it set the alarm for guiding a user to the emergency exit E with respect to the slave alarm apparatus (for example, alarm apparatus 3-3 to 3-6) of the emergency exit E vicinity. In addition, for the slave alarm device (for example, alarm devices 3-7 and 3-8) in the vicinity of the tunnel exit-side wellhead Tb, an alarm is set to prompt the user to move forward and exit the tunnel. What should I do? Alternatively, for slave alarm devices near the tunnel center (for example, alarm devices 3-3 to 3-6), the current position (the position of each alarm device) and the evacuation route (guidance to the entrance or the nearest emergency exit) An alarm may be set.

  The alarm signal generation unit 315M converts the notification signal input from the input unit 30 into an alarm signal in a communication format to the slave alarm device 3S. For example, the alarm signal generation unit 315M generates an alarm signal including address data and alarm information data corresponding to the alarm position information of each slave alarm device 3S in a frame.

  The processing unit 31S of the slave alarm device 3S includes an input / output interface (I / F) 310, a CPU 311, a storage unit 312S, and an alarm generation unit 314, which are connected to each other by a bus 316. Since the alarm signal includes alarm information associated with the address data, the alarm generation unit 314 can generate an alarm based on the alarm information. Therefore, although the storage unit 312S functions as a kind of memory, the storage unit 312S does not store data such as a reference table for generating an alarm.

  As in the first modification of the first embodiment, the present embodiment may be configured such that the alarm is determined based only on the alarm position information. Further, similarly to the second modification of the first embodiment, also in the present embodiment, the alarm signal may be relayed and transmitted by the slave alarm device 3S.

The reporting device 2 that activated the reporting signal (for example, reporting device 2-6) outputs the reporting signal to the main reporting devices 2-1 and 2-8. Then, the main notification devices 2-1 and 2-8 output notification signals to the master alarm devices 3-1 and 3-8, respectively.

  In the example shown in FIG. 11A, each slave alarm device 3S can receive alarm signals from both master alarm devices 3-1 and 3-8. Thereby, the redundancy of communication of an alarm signal is ensured.

  In FIG. 11B, each slave alarm device 3S receives an alarm signal from either one of the master alarm devices 3-1 and 3-8. In other words, the slave alarm devices 3-2 to 3-4 related to the master alarm device 3-1 and the slave alarm devices 3-5 to 3-7 related to the master alarm device 3-8 are grouped into separate groups. Is done.

  The configurations of the master alarm device 3M and the slave alarm device 3S are the same as those of the second embodiment except that the input unit 30M in the master alarm device 3M is necessarily configured by a wireless receiver. That is, the master alarm device 3M and the slave alarm device 3S display and output the same alarm as in the first embodiment by the display unit 32. Further, similarly to the first modification of the first embodiment, the present embodiment may be configured such that the alarm is determined based only on the alarm position information.

  As described above, according to the tunnel warning system 1 of the present embodiment, the advantageous effects shown in the first embodiment (1) improvement in versatility, (3) improvement in information (accuracy), and (4) information In addition to improving the property (intuition), the following advantageous effects can be obtained. The following advantageous effects become prominent when a plurality of notification devices 2 are installed, but can also be enjoyed when only one notification device 2 is installed.

(6) Improvement in infrastructure In the tunnel alarm system 1 including the notification device 2 and the plurality of alarm devices 3, a notification signal is wirelessly transmitted from each of the notification devices 2 to the master alarm device 3M, and the master alarm device 3M and the slave alarm device An alarm signal is transmitted between 3S.

An alarm system can be realized.

Embodiment 4 FIG.
In the first embodiment, the configuration in which the alarm signal is transmitted and received between the alarm devices 3 after the report signal is output from the corresponding notification device 2 to the alarm device 3 has been described. The structure which is output from each notification device 2 to the corresponding alarm device 3 after input / output between the notification devices 2 is shown.

  FIG. 14 shows a schematic diagram of the tunnel alarm system 1 according to the present embodiment. The tunnel alarm system 1 includes notification devices 2-1 to 2-8 and alarm devices 3-1 to 3-8 in the tunnel T. In this embodiment, for example, when the reporting device 2-6 is activated, the reporting signal activated by the reporting device 2-6 is sent to the other reporting devices 2-1 to 2-5, 2-7, and 2-8. After being output via the line L0, it is output from the reporting device 2-k to the corresponding alarm device 3-k via the line L1. The report signal includes report position information that identifies the report device 2 (report device 2-6) that activated the report signal. Each alarm device 3 displays and outputs an alarm position information indicating the position of the own device and an alarm based on the notification position information.

  FIG. 15 shows a block diagram of the tunnel alarm system 1 of FIG. The reporting devices 2 are connected to each other via a line L0. The reporting devices 2-1 to 2-n and the alarm devices 3-1 to 3-n are connected via lines L1-1 to L1-n, that is, the reporting device 2-k and the alarm device 3-k are connected to each other. Connected by L1-k. The reporting device 2-k and the alarm device 3-k are preferably arranged at corresponding positions. Thereby, the total length of the lines L1-1 to L1-n can be minimized.

  Each notification device 2 includes a push button 20 or a fire detection unit 21, a report activation unit 22, an output unit 23, and an input / output unit 25. The input / output unit 25 inputs / outputs a notification signal to / from the input / output unit 25 of the other notification device 2 via the line L0. The configuration of the line L0 may be a wired connection or a wireless connection, as in the second embodiment. The output unit 23 sends a report signal activated by the report activation unit 22 of the self-report device 2 or a report signal input to the input / output unit 25 to the line L1.

A notification signal is output to the device 3-k.

  Each alarm device 3 includes an input unit 30, a processing unit 31, and a display unit 32. In summary, when a notification signal from the output unit 23 of the notification device 2 is input to the input unit 30, the processing unit 31 generates an alarm based on the notification position information and the alarm position information and displays the alarm 320 on the LCD 320 of the display unit 32. Display the output. Since the alarm device 3 does not need to transmit an alarm signal to another alarm device 3, the processing unit 31 of this embodiment corresponds to a configuration in which the alarm signal generation unit 315 is removed from the processing unit 31 of FIG. In the present embodiment, the alarm output from the display unit 32 may be the same as that in the first embodiment.

  As in the first modification of the first embodiment, the present embodiment may be configured such that the alarm is determined based only on the alarm position information.

  Further, as shown in FIG. 16, similarly to the configuration of the alarm device 3 shown in the second modification of the first embodiment, a notification signal may be relayed and transmitted by another notification device 2. Thereby, even in a long tunnel, the notification signal is reliably transmitted without being attenuated or lost. In addition, since a communication method for a relatively short distance (for example, 50 m or 100 m) can be adopted as the communication method in the line L0 ′, the degree of freedom in designing the notification device 2 is increased.

  As described above, according to the tunnel warning system 1 of the present embodiment, the advantageous effects shown in the first embodiment (1) improvement in versatility, (3) improvement in information (accuracy), and (4) information In addition to sex (intuition), the following advantageous effects can be obtained.

(7) Improvement of infrastructure In the tunnel alarm system 1 including a plurality of notification devices 2 and a plurality of alarm devices 3, a notification signal is input / output between the notification devices 2 and between the alarm devices 3 corresponding to the notification devices 2. Is done. Accordingly, signal wiring between the alarm devices 3 is not required, and a tunnel infrastructure system having a high infrastructure property can be realized with a simple configuration.

Embodiment 5. FIG.
In the fourth embodiment, the notification signal is wired from each notification device 2 to each alarm device 3, but in this embodiment, the notification signal is transmitted from all or a part of the notification device 2 to each alarm device 3. Shows a configuration for wireless transmission.

  17A and 17B are schematic views of the tunnel alarm system 1 according to the present embodiment. The tunnel alarm system 1 includes notification devices 2-1 to 2-8 and alarm devices 3-1 to 3-8 in the tunnel T. In this embodiment, for example, when the reporting device 2-6 is activated, the reporting signal activated by the reporting device 2-6 is all (see FIG. 17A) or part (see FIG. 17B) of the other reporting device 2. Is sent via the line L0 to the alarm device 3 in the vicinity from the notification device 2. The report signal includes report position information that identifies the report device 2 (report device 2-6) that activated the report signal. Each alarm device 3 displays and outputs an alarm position information indicating the position of the own device and an alarm based on the notification position information.

  FIG. 18 shows a block diagram of the tunnel alarm system 1 of FIGS. 17A and 17B. The reporting devices 2 are connected to each other via a line L0. Each notification device 2 includes a push button 20 or a fire detection unit 21, a report activation unit 22, an output unit 23 including a wireless transmitter, and an input / output unit 25.

  The input / output unit 25 transmits / receives a notification signal to / from the input / output unit 25 of the other notification device 2 via the line L0. The output unit 23, which is a wireless transmitter, transmits a report signal activated by the report activation unit 22 of the self-report device 2 or a report signal input to the input / output unit 25 by wireless transmission. Similarly to the second embodiment, the configuration of the line L0 may be a wired connection or a wireless connection. The notification signal transmitted to each notification device 2 is wirelessly transmitted from the notification device 2 to the nearby alarm device 3. When the reporting device 2-k and the warning device 3-k are at corresponding positions, for example, the reporting device 2-k sends a reporting signal to the warning devices 3- (k-1), 3-k, and 3- (k + 1). May be transmitted wirelessly. However, the range of wireless transmission is not limited to the above.

  Here, whether the notification signal is wirelessly transmitted from all the notification devices 2 as shown in FIG. 17A, or whether the notification signal is wirelessly transmitted from some of the notification devices 2 as shown in FIG. 17B (or a part in that case) The number of notification devices 2) may be set as appropriate according to the communication environment in the tunnel T. For example, when the communication quality obtained in the tunnel T is low, radio transmission is performed by a larger number of reporting devices 2 to ensure reliable signal propagation, and when the communication quality is sufficiently high, fewer reporting devices. The power consumption can be suppressed by performing wireless transmission in accordance with 2.

  Note that the main notification device 2M and the sub notification device 2S may be provided as the notification device 2, and only the main notification device 2M may perform wireless transmission. For example, in the example of FIG. 17B, the reporting devices 2-2, 2-4, 2-6, and 2-8 function as the main reporting device 2M, and the reporting devices 2-1, 2-3, 2-5, and 2 -7 may function as the sub notification device 2S. In this case, the sub notification device 2S only outputs a notification signal to the line L0 and does not perform wireless transmission. Therefore, the sub notification device 2S may not have the output unit 23, and the input / output unit 25 of the sub notification device 2S only needs to have the output function.

  Moreover, it is good also as a structure by which the notification apparatus 2 is grouped and only the group relevant to the notification apparatus 2 which started the notification signal transmits a notification signal to the alarm apparatus 3 wirelessly. For example, in the example of FIG. 17B, the first group includes notification devices 2-2, 2-4, 2-6, and 2-8, and the second group includes notification devices 2-1, 2-3, 2- You may make it consist of 5 and 2-7. In this case, when any reporting device 2 in the first group activates a reporting signal, each of the reporting devices 2-1, 2-3, 3-5, and 2-7 in the first group reports Wireless transmission of signals. Similarly, when any reporting device 2 in the second group activates a reporting signal, each of the reporting devices 2-2, 2-4, 2-6 and 2-8 in the second group reports Wireless transmission of signals. The grouping is not limited to the above.

  Each alarm device 3 includes an input unit 30, a processing unit 31, and a display unit 32, and these configurations are the same as those shown in the fifth embodiment. In the present embodiment, the alarm output from the display unit 32 may be the same as that shown in the first embodiment.

  As in the first modification of the first embodiment, the present embodiment may be configured such that the alarm is determined based only on the alarm position information. Further, similarly to the configuration shown in the modified example of FIG. 16 of the fourth embodiment, the notification signal may be transmitted by being relayed by another notification device 2 in this embodiment.

  As described above, according to the tunnel warning system 1 of the present embodiment, the advantageous effects shown in the first embodiment (1) improvement in versatility, (3) improvement in information (accuracy), and (4) information In addition to sex (intuition), the following advantageous effects can be obtained.

(8) Improvement of infrastructure In the tunnel alarm system 1 composed of a plurality of notification devices 2 and a plurality of alarm devices 3, a notification signal is transmitted between the notification devices 2, and the notification signal is transmitted from the predetermined notification device 2 to the alarm device 3. Wirelessly transmitted. Accordingly, signal wiring between the alarm devices 3 is not required, and a tunnel infrastructure system having a high infrastructure property can be realized with a simple configuration.

(9) Improvement of infrastructure flexibility In the tunnel alarm system 1 including a plurality of notification devices 2 and a plurality of alarm devices 3, the number of notification devices 2 that transmit notification signals can be changed according to the communication environment. In particular, when the communication environment is good, the notification signals can be collected in a predetermined notification device 2 and transmitted to each alarm device 3. Thereby, the power consumption accompanying wireless transmission can be reduced while ensuring the communication quality of the notification signal. In addition, when the number of the reporting devices 2 that perform wireless transmission may be small, it is sufficient that only a predetermined reporting device has a wireless communication capability, and a high infrastructure tunnel alarm system with a simple configuration can be provided. Can be realized with flexibility.

Embodiment 6. FIG.
In the fifth embodiment, the configuration in which the notification signal is wirelessly transmitted from all or a part of the notification device 2 to the alarm device 3 is shown.

  FIG. 19 shows a schematic diagram of the tunnel alarm system 1 according to the present embodiment. In the tunnel T, notification devices 2-1 to 2-8 and alarm devices 3-1 to 3-8 are provided. In the present embodiment, for example, when the notification device 2-6 is activated, a notification signal activated by the notification device 2-6 is output to each of the alarm devices 3-1 to 3-8 by wireless communication. The report signal includes report position information that identifies the report device 2 (report device 2-6) that activated the report signal. Each alarm device 3 displays and outputs an alarm position information indicating the position of the own device and an alarm based on the notification position information.
