Description

この発明は、火災等の非常事態発生時に避難を促す警報システムおよび警報装置に関し、特に光によって警報を発する警報システムおよび警報装置に関する。 The present invention relates to an alarm system and an alarm device that prompts evacuation when an emergency such as a fire occurs, and more particularly to an alarm system and an alarm device that issue an alarm by light.

従来、自動火災報知設備は、所定の間隔で配設した警報用音響装置を所定の音量で鳴動させ、あるいは、連動動作させた非常放送設備によって音声メッセージを流し、火災発生を警報して避難を促すものであった。 Conventionally, automatic fire alarm equipment has been evacuated by sounding an alarm sound device arranged at a predetermined interval at a predetermined volume, or by playing an audio message through an emergency broadcasting facility that has been operated in conjunction, warning the occurrence of a fire. It was something to encourage.

しかしながら、火災等の非常事態発生時に避難するべき人に聴覚障害があるような場合、光等の聴覚以外の感覚に働きかけて非常事態を知らせる警報装置の普及が望まれている。そして、強烈な閃光を発するストロボ（登録商標）に代表されるエレクトロニック・フラッシュや、大光量のＬＥＤランプ、等を光源に用い、フラッシュ光を発する警報装置が実用化されている。 However, in the case where a person who should evacuate in the event of an emergency such as a fire has a hearing impairment, it is desired to spread an alarm device that works on a sense other than hearing such as light to notify the emergency. An alarm device that emits flash light using an electronic flash typified by a strobe (registered trademark) that emits intense flash light, a large-intensity LED lamp, or the like as a light source has been put into practical use.

従来、平常時は消灯し、火災等の非常事態発生時にフラッシュ光を発する警報装置は、その発光周期を各警報装置自体で制御するものであった。そのような警報装置を、自動火災報知設備の警報用音響装置のように所定の間隔で多数設置し、火災発生時に同時に作動させると、多数の警報装置それぞれがバラバラのタイミングで発光する。このような人工的な強い光刺激は、人に光刺激性癲癇などの光過敏性発作を引き起こす場合があることが知られている（例えば、平成９年１２月１６日に某民間テレビ放送局が放送した、強い光刺激シーンのあるテレビアニメの視聴者が光過敏性発作などを起こした事件は大きく報道され、周知である）。 Conventionally, an alarm device that is normally turned off and emits flash light in the event of an emergency such as a fire has been controlled by each alarm device itself. When a large number of such alarm devices are installed at predetermined intervals like the alarm sound device of the automatic fire alarm facility and are activated at the same time when a fire occurs, each of the many alarm devices emits light at different timings. It is known that such artificial strong light stimulation may cause photosensitivity seizures such as light-stimulating epilepsy in humans (for example, a private television broadcasting station on December 16, 1997). The case that a viewer of a TV animation with a strong light stimulation scene broadcasted by the company caused a photosensitivity attack was widely reported and well-known.

［実施の形態１］
実施の形態１について、図１および図２に基づいて説明する。 [Embodiment 1]
The first embodiment will be described with reference to FIGS. 1 and 2.

まず、図１を参照して本実施の形態に係る警報システムの構成を説明する。 First, the configuration of the alarm system according to the present embodiment will be described with reference to FIG.

火災感知器２は、火災発生時に火災を感知する火災感知手段である。 The fire detector 2 is a fire detection means for detecting a fire when a fire occurs.

火災感知器２と電路Ｌｓを介して接続された火災受信機１は、火災感知器２からの火災感知信号Ｄを受信し、この火災感知信号Ｄに基づいて火災判断を行い、火災と判断したときに、火災受信機１に備わる表示灯や音響装置等によって火災表示および火災音響警報を行う周知の火災受信機である。 The fire receiver 1 connected to the fire detector 2 via the electric line Ls receives the fire detection signal D from the fire detector 2, makes a fire determination based on the fire detection signal D, and determines that it is a fire. Sometimes it is a well-known fire receiver that performs a fire display and a fire sound alarm by means of an indicator lamp, an acoustic device or the like provided in the fire receiver 1.

火災感知器２と火災受信機１とを接続する電路Ｌｓは、図示したように火災感知器２の系統毎に個別の電路で接続するＰ型システムであっても良いし、多重伝送によって共通の電路で接続するＲ型システムであっても良い。火災受信機１が火災と判断したときは、電路Ｌｆを介して後述する警報装置３に向けて火災信号Ｆを送出するとともに、警報装置３へ電力を供給する。火災受信機１からの警報装置３への電力供給は、電路Ｌｆから送出される火災信号Ｆであっても良いし、別途専用の電源線（図示せず）を設けて警報装置３へ常時給電するようにしても良い。 The electric circuit Ls that connects the fire detector 2 and the fire receiver 1 may be a P-type system that is connected by an individual electric circuit for each system of the fire detector 2 as shown in the figure. An R-type system connected by an electric circuit may be used. When the fire receiver 1 determines that there is a fire, it sends a fire signal F to the alarm device 3 to be described later via the electric circuit Lf and supplies power to the alarm device 3. The power supply from the fire receiver 1 to the alarm device 3 may be a fire signal F sent from the electric circuit Lf, or a separate dedicated power line (not shown) is provided to constantly supply power to the alarm device 3. You may make it do.

警報装置３は、火災受信機１から送出される火災信号Ｆに基づいて所定周期でフラッシュ発光するものである。警報装置３は避難経路毎にグループ編成し、複数の警報装置３が間隔を空けて電路Ｌｆに並列接続されて配設される。なお、便宜上、それぞれの警報装置３を火災受信機１側から順に、警報装置３−１〜３−ｎ（ｎは自然数）と番号を付して区別する。 The alarm device 3 emits flash light at a predetermined cycle based on the fire signal F sent from the fire receiver 1. The alarm devices 3 are grouped for each evacuation route, and a plurality of alarm devices 3 are arranged in parallel and connected to the electric circuit Lf at intervals. For convenience, each alarm device 3 is distinguished from the fire receiver 1 in order from the alarm device 3-1 to 3-n (n is a natural number).

そして、前記グループの警報装置３−１〜３−ｎのうち、少なくとも１つの直近に非常口が存在するように警報装置３を配設する。 And the alarm device 3 is arrange | positioned so that an emergency exit may exist in the nearest at least one among the alarm devices 3-1 to 3-n of the said group.

次に、図２を参照して本実施の形態に係る警報装置３の構成を説明する。 Next, the configuration of the alarm device 3 according to the present embodiment will be described with reference to FIG.

警報装置３は、電路Ｌｆを介して火災受信機１からの火災信号Ｆを受信する受信手段である火災信号受信部３３を有し、電路Ｌｆと接続するための端子ＩＮｆを有する。 The alarm device 3 includes a fire signal receiving unit 33 that is a receiving unit that receives the fire signal F from the fire receiver 1 through the electric circuit Lf, and has a terminal INf for connecting to the electric circuit Lf.

また、警報装置３は、火災受信機１から電力の供給を受けて警報装置の各部に電力を供給する電源部３２を有する。本実施の形態では、電源部３２は電路Ｌｆを介して受信する火災信号Ｆより電力の供給を受けるようにしているが、別途専用の電源線を介して受電しても良いことは先に述べた通りである。 The alarm device 3 includes a power supply unit 32 that receives power from the fire receiver 1 and supplies power to each unit of the alarm device. In the present embodiment, the power supply unit 32 is supplied with power from the fire signal F received via the electric circuit Lf, but it may be received separately via a dedicated power line. That's right.

発光手段としての発光部３１には、強烈な閃光を発するストロボ（登録商標）に代表されるエレクトロニック・フラッシュ、あるいは、大光量のＬＥＤランプを用いることができる。なお、発光部３１に用いるデバイスはこれらに限定されるものではなく、光で警報するに足る一定以上の光量を発することができ、断続制御できる可視光の光源であれば良い。 As the light emitting unit 31 as the light emitting means, an electronic flash represented by a strobe (registered trademark) that emits intense flash light, or an LED lamp with a large amount of light can be used. Note that the device used for the light emitting unit 31 is not limited to these, and any light source that emits visible light that can emit light at a certain level or more sufficient for alarming with light can be used.

発光部３１は、図示したように制御部３８を介して電力の供給を受けても良いし、電源部３２から直接電力の供給を受け（図示せず）、発光部３１を発光させるためのトリガ信号を制御部３８から受けるようにしても良い。後者の構成は、発光手段にエレクトロニック・フラッシュを用い、これに電源部３２から放電開始に至らない高電圧を予め印加しておき、このときのエレクトロニック・フラッシュを放電させて発光を開始させるトリガ電極に制御部３８からトリガ信号を送出する用途に適している。 The light emitting unit 31 may receive power supply via the control unit 38 as illustrated, or may receive power directly from the power supply unit 32 (not shown) to trigger the light emitting unit 31 to emit light. You may make it receive a signal from the control part 38. FIG. In the latter configuration, an electronic flash is used as the light emitting means, and a high voltage that does not lead to the start of discharge is applied in advance from the power supply unit 32, and the trigger electrode that starts the light emission by discharging the electronic flash at this time is used. It is suitable for the purpose of sending a trigger signal from the control unit 38.

警報装置３は、避難経路毎にグループ編成され、前記グループにおいてフラッシュ発光を開始する順序である発光開始順序Ｎを設定する発光開始順序設定手段である発光開始順序設定部３５を有する。本実施の形態では、避難経路毎に編成したグループにおいて最も非常口から遠い警報装置３の発光開始順序Ｎが１に設定され、避難経路に沿って非常口に向かうにつれて発光開始順序Ｎが１ずつ増すように設定される。 The alarm device 3 includes a light emission start order setting unit 35 that is a group for each evacuation route and is a light emission start order setting unit that sets a light emission start order N that is the order in which flash emission is started in the group. In the present embodiment, the light emission start order N of the alarm device 3 farthest from the emergency exit in the group organized for each evacuation route is set to 1, and the light emission start order N increases by 1 as it goes to the emergency exit along the evacuation route. Set to

その設定の方法は、例えば、発光開始順序設定用のディップスイッチを設け、手動操作によって発光開始順序Ｎに相当する数値を設定する。すなわち、発光開始順序設定用のディップスイッチに設定する値を発光開始順序Ｎから１を減じた値に相当するものと定めた場合、発光開始順序Ｎが１の場合は発光開始順序設定用のディップスイッチが“０”と設定される。また、発光開始順序Ｎの値をそのまま発光開始順序設定用のディップスイッチで設定するようにしても良い。発光開始順序Ｎに相当する数値は予め定義付けて運用すれば良く、適宜決定される。 As a setting method, for example, a dip switch for setting the light emission start order is provided, and a numerical value corresponding to the light emission start order N is set by a manual operation. That is, when it is determined that the value set in the dip switch for setting the light emission start order corresponds to a value obtained by subtracting 1 from the light emission start order N, when the light emission start order N is 1, the dip for setting the light emission start order The switch is set to “0”. Alternatively, the value of the light emission start order N may be set as it is with a dip switch for setting the light emission start order. A numerical value corresponding to the light emission start order N may be defined and used in advance, and is determined as appropriate.

そして、この発光開始順序設定用のディップスイッチは外部から勝手に設定変更されないようにする。例えば、発光開始順序設定用のディップスイッチを警報装置３の内部に設け、これを操作するための開口部を施錠するようにしても良い。また、発光開始順序設定の方法は、上記のようなディップスイッチに代えて、ジャンパーピン等の他のハードウェアで設定するようにしても良いし、先に述べたようなスイッチ等のハードウェアを用いず、専用の設定ツールを用いて不揮発性メモリをセットするようなソフトウェアによる設定としても良い。 The dip switch for setting the light emission start order is prevented from being arbitrarily changed from the outside. For example, a dip switch for setting the light emission start order may be provided inside the alarm device 3, and an opening for operating the alarm device 3 may be locked. In addition, the method for setting the light emission start order may be set by other hardware such as a jumper pin instead of the above dip switch, or hardware such as the switch described above may be used. Instead of using, it may be set by software that sets a nonvolatile memory using a dedicated setting tool.

また、発光開始順序設定部で設定した発光開始順序Ｎに基づいて火災信号Ｆを受信してからフラッシュ発光を開始するまでの遅延時間ｔ０を決定する遅延時間設定手段である遅延時間設定部３６を有する。前記グループにおいて複数の警報装置３が順番にフラッシュ発光を開始するとき、予め定めた所定の時間差Δｔだけ位相をずらして所定周期Ｔで繰り返しフラッシュ発光を開始するものとし、この時間差Δｔは警報装置３が順番にフラッシュ発光するときに連続して順に発光したと人が知覚できる値、例えば０．２秒〜１秒程度とする。警報装置３毎の遅延時間ｔ０は、発光開始順序Ｎから１を減じた値に所定の時間差Δｔを乗じて決定すると良い。つまり、ｔ０＝Δｔ×（Ｎ−１）という式で表される。 Further, a delay time setting unit 36 that is a delay time setting means for determining a delay time t0 from when the fire signal F is received until the flash emission is started based on the light emission start order N set by the light emission start order setting unit. Have. When a plurality of alarm devices 3 sequentially start flash emission in the group, the flash light emission is started repeatedly at a predetermined period T by shifting the phase by a predetermined time difference Δt, and this time difference Δt is the alarm device 3. Is a value that can be perceived by humans as being sequentially emitted when the flash is emitted in sequence, for example, about 0.2 seconds to 1 second. The delay time t0 for each alarm device 3 may be determined by multiplying a value obtained by subtracting 1 from the light emission start order N by a predetermined time difference Δt. That is, it is expressed by the equation t0 = Δt × (N−1).

すなわち、発光開始順序Ｎが“１”の警報装置３は、火災信号Ｆを受信してからフラッシュ発光を開始するまでの遅延時間ｔ０がゼロとなる。ここで、火災信号Ｆを警報装置３の電力源としても利用し、発光部３１にエレクトロニック・フラッシュを用い、これを放電発光させるに足る高電圧を得るまでに要する時間等、警報装置３が起動するに要する時間ｔｓが存在するような場合は、さらにｔｓを加えて、ｔ０＝Δｔ×（Ｎ−１）＋ｔｓとすれば良い。 That is, in the alarm device 3 whose light emission start order N is “1”, the delay time t0 from when the fire signal F is received until the flash light emission is started becomes zero. Here, the fire signal F is also used as the power source of the alarm device 3, the electronic flash is used for the light emitting unit 31, and the alarm device 3 is activated, such as the time required to obtain a high voltage sufficient to discharge and emit it. If there is a time ts required for this, ts may be further added so that t0 = Δt × (N−1) + ts.

また、警報装置３は、火災信号受信部３３が火災受信機１からの火災信号Ｆを受信してからの時間ｔｘを計時する計時手段である計時部３４を有する。 In addition, the alarm device 3 includes a time measuring unit 34 that is a time measuring unit that measures a time tx after the fire signal receiving unit 33 receives the fire signal F from the fire receiver 1.

そして、計時部３４の計時結果ｔｘと遅延時間設定部３６によって決定された遅延時間ｔ０とを比較し、計時部３４の計時結果ｔｘが遅延時間ｔ０以上となったときにフラッシュ発光開始指令を出力する比較手段である比較部３７を有する。 Then, the time measurement result tx of the time measurement unit 34 is compared with the delay time t0 determined by the delay time setting unit 36, and a flash emission start command is output when the time measurement result tx of the time measurement unit 34 becomes equal to or greater than the delay time t0. The comparison unit 37 is a comparison means.

制御部３８は、発光部３１を所定周期Ｔでフラッシュ発光させる図示しない同期タイマを備え、比較部３７からのフラッシュ発光開始指令を受信すると、前記同期タイマを動作させるとともに、前記同期タイマに基づく所定周期Ｔで発光部３１をフラッシュ発光開始するように制御する制御手段である。 The control unit 38 includes a synchronization timer (not shown) that causes the light emitting unit 31 to perform flash emission at a predetermined cycle T. When receiving a flash light emission start command from the comparison unit 37, the control unit 38 operates the synchronization timer and performs predetermined processing based on the synchronization timer. This is control means for controlling the light emitting unit 31 to start flash emission at a period T.

なお、発光部３１を繰り返しフラッシュ発光させる周期である所定周期Ｔは、警報装置３それぞれに共通の値となるように、制御部３８の同期タイマで予め設定される。 Note that the predetermined period T, which is the period in which the light emitting unit 31 is repeatedly flashed, is preset by the synchronization timer of the control unit 38 so as to be a value common to each alarm device 3.

次に、図１、２を参照して、本実施の形態に係る警報システムの動作について説明する。 Next, the operation of the alarm system according to the present embodiment will be described with reference to FIGS.

なお、ここでは警報装置３−２が避難経路において最も非常口から遠い位置にあるものと仮定する。そして、警報装置３−２の発光開始順序Ｎは発光開始順序設定部３５で“１”に設定され、避難経路に沿って隣接する警報装置３−１、３−３（図示せず）の発光開始順序Ｎは発光開始順序設定部３５で“２”に設定され、避難経路に沿って末端側の非常口に向かうにつれて、それぞれの警報装置３の発光開始順序Ｎは発光開始順序設定部３５で１ずつ増加するように設定される。 Here, it is assumed that the alarm device 3-2 is at a position farthest from the emergency exit on the evacuation route. The light emission start order N of the alarm device 3-2 is set to “1” by the light emission start order setting unit 35, and the light emission of the alarm devices 3-1 and 3-3 (not shown) adjacent along the evacuation route is performed. The start order N is set to “2” by the light emission start order setting unit 35, and the light emission start order N of each alarm device 3 is set to 1 by the light emission start order setting unit 35 as it goes to the emergency exit on the terminal side along the evacuation route. It is set to increase by one.

火災発生時に火災感知器２が火災を感知すると、火災感知器２は電路Ｌｓを介して火災感知信号Ｄを火災受信機１へ送出する。そして、火災受信機１は、火災感知信号Ｄに基づいて火災判断を行い、火災と断定すると電路Ｌｆを介して、火災発生階やその直上階に属するグループの警報装置３−１、警報装置３−２、・・・警報装置３−ｎへ火災信号Ｆを送出する。なお、全てのグループの警報装置３へ火災信号Ｆを送出するようにして、全館に警報するようにしても良い。 When the fire detector 2 detects a fire when a fire occurs, the fire detector 2 sends a fire detection signal D to the fire receiver 1 via the electric circuit Ls. Then, the fire receiver 1 makes a fire determination based on the fire detection signal D, and when it is determined that a fire has occurred, via the electric circuit Lf, the alarm device 3-1 and the alarm device 3 of the group belonging to the floor where the fire has occurred or directly above it. -2, ... Sends fire signal F to alarm device 3-n. Note that the fire signal F may be sent to the alarm devices 3 of all groups so that the entire building is warned.

火災信号Ｆを受信した警報装置３−１、３−２、・・・３−ｎは、火災信号Ｆを受信してから、それぞれが発光開始順序Ｎで定まる遅延時間ｔ０の後に、共通の所定周期Ｔで繰り返しフラッシュ発光を開始する。 The alarm devices 3-1, 3-2,..., 3-n that have received the fire signal F, after receiving the fire signal F, after the delay time t 0 determined by the light emission start order N, Flash emission is started repeatedly at period T.

すなわち、発光開始順序が“１”に設定された警報装置３−２が最初にフラッシュ発光を開始し、次いで避難経路に沿って警報装置３−２に隣接し、発光開始順序が“２”に設定された警報装置３−１、３−３がΔｔの時間差で遅れてフラッシュ発光を開始する。このようにして、非常口から最も遠い警報装置３−２から避難経路に沿って末端側に位置する非常口に向かって、Δｔの時間差で順に、他の警報装置３がフラッシュ発光を開始する。 That is, the alarm device 3-2 whose light emission start order is set to “1” first starts flash light emission, then is adjacent to the alarm device 3-2 along the evacuation route, and the light emission start order is set to “2”. The set alarm devices 3-1 and 3-3 start flash emission with a delay of Δt. In this way, the other alarm devices 3 start flash emission sequentially from the alarm device 3-2 farthest from the emergency exit toward the emergency exit located on the terminal side along the evacuation route with a time difference of Δt.

そして、これらの警報装置３は、すべて共通の発光周期Ｔでフラッシュ発光を繰り返すので、前記グループにおいて最も非常口から遠い警報装置３−２を開始点として隣接する警報装置３が避難経路に沿ってその末端に位置する警報装置３−１および３−ｎに向かって順にフラッシュ発光する動作を繰り返し、避難経路の末端に位置する非常口に向かって避難誘導する。
［実施の形態２］
実施の形態２について、図１、３に基づいて構成を説明する。なお、実施の形態１と同じ構成には同一の符号を付して、説明を省略する。また、図１における符号は、図３に基づいて読み替えるものとする。 All of these alarm devices 3 repeat flash emission with a common light emission period T, so that the adjacent alarm device 3 starts from the alarm device 3-2 farthest from the emergency exit in the group along the evacuation route. The flashing operation is repeated in order toward the alarm devices 3-1 and 3-n located at the end, and the evacuation is guided toward the emergency exit located at the end of the evacuation route.
[Embodiment 2]
The configuration of the second embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the same structure as Embodiment 1, and description is abbreviate | omitted. Further, the reference numerals in FIG. 1 are read based on FIG.

本実施の形態の構成が、実施の形態１と異なる点は、同期信号受信手段である同期信号受信部３９を備え、制御部３８に代えて、同期信号受信部３９からの同期補正信号を受信すると図示しない同期タイマを同期させるようにした制御部３８０を備え、このような構成を備えた警報装置３０としたことにある。 The configuration of the present embodiment is different from that of the first embodiment in that it includes a synchronization signal receiving unit 39 that is a synchronization signal receiving unit, and receives a synchronization correction signal from the synchronization signal receiving unit 39 instead of the control unit 38. Then, the control unit 380 configured to synchronize a synchronization timer (not shown) is provided, and the alarm device 30 having such a configuration is provided.

また、火災受信機１と警報装置３との間に介在して、警報装置３０それぞれが制御部３８０に有する図示しない同期タイマの脱調を補正する、同期補正信号を出力する図示しない同期補正手段を設けたものである。 Further, a synchronization correction unit (not shown) that outputs a synchronization correction signal that is interposed between the fire receiver 1 and the alarm device 3 and corrects the step-out of a synchronization timer (not shown) that each alarm device 30 has in the control unit 380. Is provided.

この同期補正手段は、例えば図示しない同期補正用の中継器として、図１における電路Ｌｆの火災受信機１側の基端部に介在させるように設け、火災信号Ｆに重畳させるように前記同期補正信号を出力するように設けることができる。また、この同期補正手段は、上記の同期補正用の中継器を火災受信機１の内部に設け、電路Ｌｆを介して、警報装置３０へ火災信号Ｆを送出するとともに、火災信号Ｆに前記同期補正信号を重畳させるように出力するようにしても良い。また、電路Ｌｆとは全く異なる新たな電路を敷設して、火災受信機１と警報装置３０との間に介在するように配設しても良く、適宜決定される。 This synchronization correction means is provided, for example, as a synchronization correction repeater (not shown) so as to be interposed at the base end portion on the fire receiver 1 side of the electric circuit Lf in FIG. It can be provided to output a signal. The synchronization correction means includes the above-described synchronization correction repeater provided inside the fire receiver 1, sends a fire signal F to the alarm device 30 through the electric circuit Lf, and also synchronizes with the fire signal F. You may make it output so that a correction signal may be superimposed. Further, a new electric circuit completely different from the electric circuit Lf may be laid and disposed so as to be interposed between the fire receiver 1 and the alarm device 30 and is determined as appropriate.

次に本実施の形態の動作について、図１、３を参照して説明する。なお、図１における符号は、図３に基づいて読み替えるものとする。 Next, the operation of the present embodiment will be described with reference to FIGS. Note that the reference numerals in FIG. 1 are read based on FIG.

実施の形態１の各警報装置３の制御部３８に備わる図示しない同期タイマは、火災信号Ｆを受信すると同時に動作を開始し、各警報装置３に共通な所定周期Ｔで発光部３１をフラッシュ発光させるように制御している。このとき、前記同期タイマは同時に動作を開始しているので、動作する位相も揃う（図２を参照）。 A synchronization timer (not shown) provided in the control unit 38 of each alarm device 3 according to the first embodiment starts operating simultaneously with receiving the fire signal F, and flashes the light emitting unit 31 at a predetermined cycle T common to each alarm device 3. It is controlled to let you. At this time, since the synchronous timers start operating simultaneously, the operating phases are aligned (see FIG. 2).

しかしながら長い時間動作させていると、前記同期タイマ自体の精度により、各警報装置３に共通なはずの所定周期Ｔが次第にずれてしまい、一斉に同じ動作をしていた前記同期タイマの揃っていた位相がずれてしまう“脱調”が発生する虞がある。 However, when operated for a long time, due to the accuracy of the synchronization timer itself, the predetermined period T that should be common to each alarm device 3 gradually shifts, and the synchronization timers that were operating at the same time were aligned. There is a risk of “out-of-step” causing a phase shift.

これを防ぐには、第１に前記同期タイマの精度を高めることである。例えば水晶発振子等を用い、高精度の発振に基づいて同期タイマを動作させれば良い。 To prevent this, first, the accuracy of the synchronization timer is increased. For example, a synchronous oscillator may be operated based on high-precision oscillation using a crystal oscillator or the like.

しかしながら、このような方法はコスト上昇を招く。そこで、本実施の形態では、前記同期タイマの精度を必要最小限に抑えて安価に実現できるようにし、脱調を防ぐために周期的な同期補正を行う制御としたものであり、前記同期タイマの精度に応じて周期的に同期を補正するようにした。 However, such a method causes an increase in cost. Therefore, in the present embodiment, the accuracy of the synchronization timer is controlled to the minimum necessary so that it can be realized at low cost, and periodic synchronization correction is performed to prevent step-out. The synchronization was corrected periodically according to the accuracy.

すなわち、前記同期補正手段は、所定周期Ｔの整数倍の時間間隔で同期補正信号を警報装置３０に送出し、警報装置３０は同期信号受信部３９で前記同期補正信号を受信すると、警報装置３０それぞれの制御部３８０が備える図示しない同期タイマを同期させる。 That is, the synchronization correction means sends a synchronization correction signal to the alarm device 30 at time intervals that are integral multiples of the predetermined period T. When the alarm device 30 receives the synchronization correction signal at the synchronization signal receiver 39, the alarm device 30 A synchronization timer (not shown) included in each control unit 380 is synchronized.

このように同期補正信号を所定周期Ｔの整数倍の時間間隔で警報装置３０へ送出することにより、同期補正時のフラッシュ発光のタイミングのずれを最小限に抑えることができる。なお、前記整数倍の時間間隔をどの程度とするかは、用いる同期タイマの精度によって適宜決定される。 Thus, by sending the synchronization correction signal to the alarm device 30 at time intervals that are integral multiples of the predetermined period T, it is possible to minimize the deviation in the timing of flash emission during synchronization correction. It should be noted that the extent of the integer multiple time interval is appropriately determined depending on the accuracy of the synchronization timer used.

なお、本発明の実施の形態は上記したものに限るものではなく、様々な応用が可能である。 The embodiment of the present invention is not limited to the above-described embodiment, and various applications are possible.

例えば、実施の形態１または２において、全ての警報装置３または３０の発光開始順序をすべて“１”とするようにしても良い。このように設定すると、避難経路毎にグループ編成された警報装置３または３０は、まったく同じタイミングで同期してフラッシュ発光するようになる。 For example, in the first or second embodiment, all the light emission start orders of all the alarm devices 3 or 30 may be set to “1”. If set in this way, the alarm devices 3 or 30 grouped for each evacuation route will flash in synchronism with exactly the same timing.

したがって、非常口に向かって順にフラッシュ発光して避難誘導することはできないが、光過敏性発作を引き起こすことなく、聴覚障害がある人にも火災発生を知らせて避難を促すことができるという、当初の第一の目的を達成することができる。そして、すべての警報装置３または３０の発光開始順序を工場出荷時に“１”に設定しておけば、デフォルトの設定のまま設置工事して発光開始順序の設定を行わなくても、上記第一の目的を達成することができる。したがって、避難誘導経路をフラッシュ発光で知らせる必要が無いような小規模施設等に設置する場合で、聴覚障害がある人にも火災発生を知らせて避難を促すことが目的であれば、発光開始順序の設定を設置現場で行う必要が無く、工場でのデフォルト設定のままで用いることができるので、人件費を削減し、より安価に警報システムを提供することができる。 Therefore, it is not possible to guide the evacuation by flashing in order toward the emergency exit, but it is possible to notify the person with hearing impairment that the fire has occurred and prompt the evacuation without causing a photosensitivity attack. The first objective can be achieved. If the light emission start order of all the alarm devices 3 or 30 is set to “1” at the time of shipment from the factory, the above first setting can be performed without setting the light emission start order by performing installation work with the default settings. Can achieve the purpose. Therefore, if it is installed in a small-scale facility where there is no need to inform the evacuation guidance route by flash emission, if the purpose is to notify people with hearing impairments of the occurrence of a fire and encourage evacuation, the order of light emission start Since it is not necessary to perform the setting at the installation site and can be used with the factory default setting, the labor cost can be reduced and the alarm system can be provided at a lower cost.
