Description

  The present invention relates to a repeater that automatically senses an abnormal situation such as a fire and relays communication between components of a disaster prevention facility that performs operations such as alarm, display, and interlock control.

For apartment houses that meet certain conditions, automatic fire alarm equipment (hereinafter referred to as “self-fire alarm equipment”) was exempted, but in recent years the welfare of small-scale group homes using part of apartment houses The number of cases where facilities are established is increasing, and it is necessary to newly install disaster prevention facilities.
Conventional self-reporting equipment, etc. is basically wired communication, but when installing new disaster-prevention equipment in an existing building that is not equipped with disaster prevention equipment such as self-reporting equipment, ensure a dedicated electric circuit. It was difficult. Although it is not impossible to construct a new electric line by constructing a new construction, it is a large-scale construction in a building that has already lived, so there is a great mental burden on the inhabitants, and it is economical for the owner. Since the burden is large, disaster prevention equipment that does not require new electric circuit laying work is desired.
Therefore, a wireless disaster prevention facility is awaited. For example, Patent Document 1 proposes an idea that a wireless relay station called a floor terminal is provided for each floor, and communication with each dwelling unit or the like is performed wirelessly on a floor basis.

JP 2003-069723 A

It is not possible. In addition, there is a problem that wireless communication to each floor terminal (such as a dwelling unit) is restricted depending on the radio wave arrival distance from each floor terminal and the state of the route. For example, the end of a long corridor bends in an L shape, and a terminal (such as a dwelling unit) at the end of the long corridor may be behind a building body and do not receive radio waves, causing a communication failure.
With the radio wave reach of a low-power wireless device, communication that covers the entire building is impossible, and relay communication using low-power wireless communication is indispensable to avoid opening a new wireless station.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a repeater that enables highly redundant communication.

The fire detector 2 includes an antenna 21 and a transmission / reception unit 22 for performing wireless communication, a fire detection unit 25 for detecting a fire by a physical phenomenon such as smoke or heat, a storage unit 24 for storing event information, Information on the event of fire alarm generated by the operation of the fire detection unit 25 is sent to the transmission / reception unit 22 and stored in the storage unit 24 to perform internal control such as lighting of the fire confirmation lamp, and the received test And a control unit 23 for controlling an internal test or the like by a control signal such as. The fire detector 2 also has a function of returning a status signal in a timely manner by a signal received via the outdoor repeater 3, performing a remote inspection, and returning the result.
The fire detectors 2 are arranged in the appropriate number for the fire detection in each divided alert area, and exchange information with the outdoor repeater 3 described later by wireless communication.

The outdoor repeater 3 controls the antenna 31 and the transmission / reception unit 32 for performing wireless communication, the storage unit 34 for storing event information, and the transmission / reception unit 32, and communicates with the fire detector 2 for reception. And a control unit 33 that stores the event information stored in the storage unit 34 and controls relay communication with other wireless relay devices.
The outdoor repeater 3 connects another wireless relay device to a disaster prevention device such as a fire detector 2 disposed in the room, and functions as a first repeater of the present invention.

  The trunk repeater 4 controls an antenna 41 and a transmission / reception unit 42 for performing wireless communication, a storage unit 44 for storing event information and the like, and the transmission / reception unit 42 to receive event information received from an adjacent wireless relay device. A controller 43 that stores in the storage unit 44 and controls relay communication with another wireless relay device, and the wireless relay communication reaches the wireless relay device such as the outdoor repeater 3 and the district acoustic device 5 described later. It acts as a second repeater of the present invention which is used in a place where it is not present. Further, the main line repeater 4 is appropriately arranged for the purpose of securing a plurality of communication paths.

  The district acoustic device 5 includes an antenna 51 and a transmission / reception unit 52 for performing wireless communication, an acoustic device 55 that rings according to a command signal emitted from the fire receiver 1, a storage unit 54 that stores event information, and the transmission / reception unit. Control unit 52, stores event information received from an adjacent wireless relay device in the storage unit 54, and includes a control unit 53 that controls relay communication with other wireless relay devices, and is suitable for a common part such as a corridor It acts as a sound device that is arranged at the time of a fire and warns the residents of the situation, and also acts as a second repeater of the present invention that performs wireless relay communication similar to the trunk repeater 4 .

Next, the example of arrangement | positioning which installed said disaster prevention equipment component apparatus in the apartment building of 3 stories is shown in FIG.2 and FIG.3. 2 is a plan view of each floor, and FIG. 3 is a vertical sectional view of the building.
Here, the fire receiver 1 corresponds to the management room, the fire sensor 2 corresponds to each dwelling unit, the management room, the lobby, the top of the staircase, and the hallway, and the outdoor repeater 3 corresponds to the fire sensor 2, , Outdoor in the veranda of each dwelling unit, outdoor in the immediate vicinity of the management room, outdoor in the immediate vicinity of the lobby such as the entrance, etc. The district acoustic device 5 is installed in each floor corridor at the staircase landing where no wireless relay device exists.

An example of a wireless relay communication path between these disaster prevention equipment components is shown in FIGS. 4 is a plan view of each floor, and FIG. 5 is a vertical sectional view of each part of the building. Note that the shared corridor of this building is not an open corridor that is open to the outdoors, but is provided indoors.
The fire detectors 2 communicate with the corresponding outdoor repeaters 3 through paths individually connected by broken arrows. The outdoor repeater 3 may communicate with a plurality of adjacent security areas, that is, a plurality of living rooms. However, for the sake of simplicity, the outdoor repeater 3 does not communicate with other adjacent devices. The communication between the fire receiver 1 and the outdoor repeater 3 arranged in the management room is the same.

  The outdoor repeater 3 disposed outdoors communicates with the adjacent outdoor repeaters 3 through a mesh-like route connected by arrows. Depending on the reach of the wireless communication, communication may be performed with the outdoor repeater 3 that is farther than the adjacent outdoor repeater 3 or the indoor wireless repeater. It is assumed that relay communication is performed only between the repeaters 3. However, it is assumed that the fire receiver 1 and the immediate outdoor repeater 3 communicate with each other.

  The outdoor repeater 3 disposed indoors is disposed corresponding to the fire detector 2 and the district sound device 5 disposed in each floor corridor, and wirelessly relays between the floors via the space of the staircase. , Placed on each floor of the staircase or on the landing. The corresponding fire detector 2 communicates with a route connected by a broken arrow, and communicates with other wireless relay devices via a route connected by a solid arrow.

The trunk repeater 4 installed indoors is a lower layer of the right staircase that becomes a blank area for wireless relay communication without the outdoor repeater 3 being arranged in a vertical communication path using the space of the right staircase. It is arranged at the landing part of the floor or in the vicinity thereof and complements the communication path.
The district sound device 5 is provided on each floor to notify the occupants of the occurrence of a fire and also acts as a communication path that connects the vertical communication paths using the two staircases in the horizontal direction. In addition, when the common corridor of this building is an open type corridor, the path | route which the said outdoor repeater 3 and the district sound apparatus 5 installed in the corridor of each floor communicates in a perpendicular direction across a floor is added.

About the disaster prevention equipment mentioned above, the example of operation | movement at the time of fire alerting is shown in FIG.6 and FIG.7. Here, for the sake of convenience, it is assumed that a fire has occurred in room 202.
The fire detector 2 in room 202 is detected by the fire detection unit 25, and the control unit 23 stores this fire alarm event as information in the storage unit 24 and sends a signal to the transmission / reception unit 22 to fire from the antenna 21. The alarm signal is transmitted by radio waves, and the fire alarm signal is transmitted by wireless communication to the outdoor repeater 3 installed in the outdoor part of the room. The fire detector 2 and the outdoor repeater 3 may have unique identification information for each alert area, thereby preventing interference with other rooms.

  The outdoor repeater 3 that has received the fire alarm signal first receives the radio wave by the antenna 31, takes out the fire alarm event information by the transmission / reception unit 32, and sends it to the control unit 33. In addition to storing the notification event in the storage unit 34, the specific event for identifying the occurrence location in the fire alarm event information to the adjacent outdoor repeater 3 from the antenna 31 via the transmission / reception unit 32 A signal radio wave with identification information added is transmitted. If there is a retransmission request via the adjacent outdoor repeater 3, the fire alarm event information stored in the storage unit 34 is read out and the signal radio wave similar to the above is retransmitted.

  Since the signal radio wave is transmitted via the same antenna 31 after receiving the fire alarm signal from the fire detector 2, communication is established in mutual communication with the fire detector 2 by this time. It is desirable to stop the transmission of the signal radio wave from the fire detector 2 by transmitting the communication end accompanying it. As a result, the outdoor repeater 3 can quickly move to the next transmission operation, and can reduce the power consumption of the fire detector 2.

  In this case, three outdoor repeaters 3 adjacent to the outdoor repeater 3 are installed outside the room 201, outdoors near the lobby, and outdoors near the management room. Of course, signal radio waves are also transmitted to other adjacent outdoor repeaters, etc., but signal radio waves relayed wirelessly from these are always installed in the management room unless they pass through the three outdoor repeaters. Not transmitted to fire receiver. Here, when the outdoor repeater 3 is operated so as not to relay and communicate the same signal as the signal transmitted by itself, these unnecessary signal radio waves are eliminated, and unnecessary wireless relay is not required. Thereby, congestion can be reduced and stable wireless communication can be performed, and the power consumption of the outdoor repeater 3 can be reduced. In particular, when the disaster prevention equipment constituting apparatus such as the outdoor repeater 3 uses a battery as a power source, it is possible to prevent the battery from being consumed.

  The three outdoor repeaters 3 that have received the signal radio wave each receive the radio wave by the antenna 31, take out the fire alarm event information by the transmission / reception unit 32, and send it to the control unit 33. The notification event is stored in the storage unit 34, and the signal radio wave is relayed from the antenna 31 to the other outdoor repeater 3 or the fire receiver 1 via the transmission / reception unit 32. Become.

  However, in this case, the outdoor repeater 3 in the immediate vicinity of the control room, which is the final relay point for relay communication to the fire receiver 1, is already receiving signal radio waves from the outdoor repeater 3 in the outdoor room 202. Therefore, the other two outdoor repeaters 3 should not transmit signal radio waves in order to prevent interference. This can be solved by performing control that does not transmit while the wireless relay device such as the adjacent outdoor repeater 3 is transmitting. However, after the transmission from the outdoor repeater 3 in the outdoor room 202 to the outdoor repeater 3 in the immediate vicinity of the control room is completed, the outdoor repeater 3 in the immediate vicinity of the control room transmits to the fire receiver 1, It is also necessary to avoid the collision of the signal radio waves by the other two outdoor repeaters transmitting the signal radio waves. This means that the transmitting side transmits a transmission request signal, the receiving side receiving it transmits a synchronization signal, performs transmission and reception intermittently, and divides the reception period in time slots to provide time slots. The solution is to assign a different time slot for each.

As described above, the outdoor repeater in the immediate vicinity of the management room, which is the final relay location, can perform wireless relay communication with the fire receiver 1.
The fire receiver 1 installed in the management room receives the signal radio wave with the antenna 11, takes out the fire alarm event information with the transmitter / receiver 12 and sends it to the controller 13, and the controller 13 stores the fire alarm event in the memory unit. 14, the display operation unit 15 is controlled, the occurrence of the fire alarm and the occurrence location thereof are displayed, the main acoustic device is sounded, and the occurrence of the emergency situation is warned.

Next, FIG.8 and FIG.9 shows the operation example at the time of the fire alarm in the building after a fire alert. Here, for the sake of convenience, the operation will be described as a continuation of the operation at the time of fire alarm described so far.
As described above, it is assumed that the fire receiver 1 that has received the fire report in the room 202 performs control for ringing the district acoustic devices on the fire floor and the directly above floor. Actually, although not shown in the figure, terminal devices for fire prevention / smoke / smoke equipment such as fire doors, fire shutters, fire dampers, smoke exhaust devices, etc. are remotely connected in conjunction with the fire alarm or manually. Although control may be performed, although the control target is different, these operations are the same as the control of the district sound device described here, and thus will be omitted.

The fire receiver 1 that has received the fire report in room 202 determines that the fire floor is the second floor and that the floor directly above is the third floor. Therefore, in this case, among the district acoustic devices 5, those disposed in the second and third floor corridors are ringed.
The fire receiver 1 searches for communication path information that has been searched and stored in advance, determines the optimum communication path to the target terminal device, and includes path information including identification information unique to the target terminal device. And a signal radio wave including control content is transmitted according to the route information. The wireless relay device that has received this relays the signal to the next wireless relay device based on the route information when the identification information of the own device is included in the route information included in the received signal information.

In this case, the following two routes are determined.
First, the first route is a relay communication route for the control signal for ringing the district acoustic device 5 on the second floor corridor, “the outdoor repeater 3 on the first floor of the left staircase”, “the outdoor on the second floor of the left staircase” “Repeater 3”, “District audio device 5 on the second floor corridor”. Similarly, the second route is “an outdoor repeater 3 on the first floor of the left staircase”, “an outdoor repeater 3 on the second floor of the left staircase”, “an outdoor repeater 3 on the third floor of the left staircase” , “District audio device 5 on the third floor corridor”.

  According to this route information, the fire receiver 1 emits signal radio waves for controlling the two terminal devices to the outdoor repeater 3 on the first floor of the left staircase. Even if another adjacent wireless relay device receives this, if there is no identification information unique to the own device in the route information included in the signal, it is ignored without doing anything.

  The outdoor repeater 3 on the first floor portion of the left staircase receives the signal radio wave with the antenna 31, reads out the path information and control contents included in the signal radio wave with the transmission / reception unit 32, and sends them to the control unit 33. Since the control unit 33 includes identification information unique to the own device in the route information, the control unit 33 recognizes that it should take some action, and from the identification information at the end of the route information and the control content, It is determined that a command for relay communication is received according to the information. Then, relay communication is performed by retransmitting the same information as the received signal radio wave.

  Next, the outdoor repeater 3 on the left staircase 2nd floor operates in the same manner as described above. Even when the adjacent radio relay apparatus receives the signal radio wave, if there is no identification information unique to the own device in the route information included in the signal, it can be ignored without doing anything. However, after that, the path branches toward the terminal device for control purposes.

  For the first route, the signal radio wave reaches the target area acoustic device 5 on the second floor corridor. That is, the district acoustic device receives the signal radio wave with the antenna 51, reads out the route information and the control content with the transmission / reception unit 52, and sends it to the control unit 53. Receiving this, the control unit 53 stores the information in the storage unit 54, and since the identification information unique to the own device is the final information of the route information and the control content is sounding, The sound device 55 is sounded.

  For the second route, the signal radio wave reaches the target acoustic device 5 on the third floor corridor via the outdoor repeater 3 on the third floor of the left staircase, and the second acoustic device on the second floor corridor It rings similarly.

The district sound device ringing in this manner returns operation confirmation information to the fire receiver. That is, the order of the route information stored in the storage unit 54 of the own device is reversed, and control completion information is added to the route information and transmitted as a signal radio wave.
The wireless relay device on the path that has received this signal radio wave follows the reverse path to that when the district sound ringing command is issued, and makes the fire receiver 1 recognize that the command has arrived and executed.

  By the way, if the target area acoustic device does not operate on the relay communication path due to a sudden radio wave failure or a failure of the wireless relay device, the operation confirmation information is not returned. In this case, the fire receiver 1 searches for other communication paths from the stored path information, and tries to perform remote control based on this. In this case, a route through the trunk repeater 4 or the outdoor repeater 3 in the right staircase portion is commanded somewhere on the route. As described above, by arranging the wireless relay device in advance so as to secure a plurality of wireless relay routes, the disaster prevention equipment of the present invention has high redundancy and can perform a reliable operation.
