Description

Lighting device and lighting system

本発明は、誘導灯や非常灯のように、常用の電源が停電したときに２次電池などの非常用の電源でランプを点灯させ、特に点検機能を持つ照明装置に関するものである。 The present invention relates to an illuminating device having an inspection function, such as a guide light or an emergency light, which turns on a lamp with an emergency power source such as a secondary battery when a normal power source fails.

誘導灯や非常灯の点検は、消防庁告示、建築基準法等で義務付けされているが、規定では誘導灯が２０分間又は６０分間、非常灯の場合は３０分間、ランプを有効に２次電池で非常点灯させなければいけない。従って、通常点検者は、このように長時間点灯させ続けるために、点検スイッチの引き輪に重りをぶら下げるなどして、上記規定時間内にランプが有効に非常点灯可能か否かを見て廻る必要があり、非常に手間のかかる作業であった。 The inspection of guide lights and emergency lights is obligated by the Fire and Disaster Management Agency Notification, Building Standards Law, etc., but by regulation, the guide lights are used for 20 minutes or 60 minutes, and in the case of emergency lights, the lamps are used effectively for 30 minutes. It must be lit at the emergency. Therefore, in order to keep the light on for a long time in this way, the normal inspector looks around whether the lamp can be effectively lit within the specified time by hanging a weight on the pulling wheel of the inspection switch. It was necessary and very laborious.

そこで、点検作業の省力化を図るために点検作業を自動化する方法が、特願２００２−２７９７６０に開示されている。上述される開示例における照明装置では、正確な点検を行うために、満充電されていない状態で２次電池の点検が行われないよう、常用電源の通電時間が所定充電時間（誘導灯では２４時間、非常灯では４８時間）に達するまでは点検を開始しないことを特徴としている。 Therefore, Japanese Patent Application No. 2002-279760 discloses a method of automating the inspection work in order to save labor of the inspection work. In the lighting device in the above-described disclosure, in order to perform an accurate inspection, the energization time of the normal power supply is set to a predetermined charging time (24 for the guide light) so that the secondary battery is not inspected in a state where it is not fully charged. The inspection is not started until the time reaches 48 hours for emergency lights.

なお、特許文献１には、点検者が短時間だけ点検スイッチをオンすれば、点検シーケンス手段によって所定の点検作業が実行され、２次電池に異常があれば表示手段で表示することで２次電池の点検作業の自動化、省力化を図った照明装置が提案されている。
特開平８−１８５９８７号公報 In Patent Document 1, if the inspector turns on the inspection switch for a short time, a predetermined inspection operation is performed by the inspection sequence means, and if there is an abnormality in the secondary battery, the display means displays the secondary battery. There has been proposed a lighting device that automates battery inspection work and saves labor.
JP-A-8-185987

特願２００２−２７９７６０では、満充電されていない状態で２次電池の点検が行われるのを防ぐことが出来るが、所定充電時間（２次電池が規定時間放電による点検を行うのに必要な電気量を充電する時間）に到達する前に短時間の停電（例えば瞬時停電や、点検スイッチやブレーカー等の誤操作）が発生すると、復電してから再び所定充電時間経過しなければ、点検可能な状態にならない。また、所定充電時間に到達して点検可能な状態で短時間の停電が発生しても、復電してから所定時間充電しないと点検可能な状態にならないという課題がある。 In Japanese Patent Application No. 2002-279760, it is possible to prevent the secondary battery from being inspected in a state where it is not fully charged, but a predetermined charging time (electricity necessary for the secondary battery to perform inspection by discharging for a specified time) If a short-time power outage (for example, an instantaneous power outage or an erroneous operation of the inspection switch or breaker) occurs before reaching the amount of time), inspection can be performed if the specified charging time does not elapse after the power is restored. It will not be in a state. In addition, even if a short-time power failure occurs in a state where the predetermined charging time has been reached and can be inspected, there is a problem that the inspection cannot be performed unless charging is performed for a predetermined time after power recovery.

本発明は、このような点に鑑みてなされたものであり、その目的とするところは、瞬時停電が起こりやすい場所や、容易に点検スイッチを押せる場所においても、確実に点検を行えるようにすることにある。 The present invention has been made in view of the above points, and the object of the present invention is to make sure that inspection can be performed even in a place where an instantaneous power failure is likely to occur or a place where an inspection switch can be easily pressed.

If there is, the count value is not initialized, and the charging time count after power recovery is continued from the state immediately before the occurrence of the power failure.

請求項１の発明によれば、所定充電時間到達前に短時間の停電が起こっても、充電時間を継続してカウントするので、再び初期値から所定充電時間経過するのを待たなくても点検が出来るようになる。また、所定充電時間到達後に短時間の停電が起こった場合は、点検可能な状態を継続出来る。
請求項２の発明によれば、所定充電時間経過していない状態でも、その時点での充電時間に応じて判定時間を変えることによって、充電状態であれば常に点検可能な状態となり、２次電池の充放電効率の劣化などを早期に検出することができる。 According to the first aspect of the present invention, even if a short interruption occurs before the predetermined charging time is reached, the charging time is continuously counted. Therefore, the inspection can be performed without waiting for the predetermined charging time to elapse from the initial value again. Will be able to. Moreover, when a short-time power failure occurs after the predetermined charging time is reached, it is possible to continue the checkable state.

請求項３の発明によれば、所定充電時間経過した状態から停電によって放電した時間と、復電してからの充電時間によって判定時間を変化させることで、所定充電時間経過した状態を基準としているので、請求項２よりも判定精度を向上させることができ、容量低下を早期に検出することができる。
請求項４の発明によれば、充電時間と放電時間から充電電気量と放電電気量を求め、補充電時間と判定時間を常に算出することで、常に点検可能な状態とすることができ、かつ２次電池の判定精度を向上させることができる。 According to the invention of claim 3, the determination time is changed based on the time when the predetermined charging time has elapsed and then the discharge time due to a power failure, and the charging time after the power recovery, so that the state where the predetermined charging time has elapsed is used as a reference. Therefore, the determination accuracy can be improved as compared with the second aspect, and the capacity drop can be detected at an early stage.
According to the invention of claim 4 , by obtaining the charge electricity amount and the discharge electricity amount from the charge time and the discharge time, and always calculating the auxiliary charge time and the determination time, it can be in a state that can always be inspected, and The determination accuracy of the secondary battery can be improved.

（実施形態１）

As shown in FIG. 1, the lighting device of this embodiment includes a secondary battery 1 serving as an emergency power source, a lamp 2 including an incandescent lamp and a discharge lamp, and a power supply connected to a regular power source (commercial power source AC). An inspection switch 3 that opens and closes the path; a power supply circuit unit 4 that is connected to the power supply path via the inspection switch 3 and that steps down and stabilizes the alternating current supplied from the commercial power supply AC to obtain a desired direct current; The charging unit 5 that charges the secondary battery 1 with the DC power output from the battery, the lighting circuit unit 6 that lights the lamp 2 by power supply from the secondary battery 1, and the lighting circuit unit 6 from the secondary battery 1 to the lighting circuit unit 6 A switch element Q that opens and closes the power supply path, a control unit 7 that detects power failure and power recovery of the commercial power supply AC to turn on and off the switch element Q, and detects abnormality of the secondary battery 1 and the lamp 2, and the like An indicator lamp 13 for informing the detection; Provided always are those supplied with power from the commercial power source AC to charge the secondary battery 1, to turn on the lamp 2 is very light in power supply from the secondary battery 1 when the commercial power source AC failure.

制御部７はタイマ機能を内蔵したマイクロコンピュータを主構成要素とし、充電部５から２次電池１へ流れる充電電流の有無を検出する充電検出部８と、２次電池１の電圧（以下、「電池電圧」という）を検出する電圧検出部９と、点灯回路部６からランプ２に流れる電流（ランプ電流）を計測してランプ２の点灯、不点灯を検出する点灯検出部１０と、各検出部８，９，１０の検出結果から２次電池１やランプ２の異常を総合的に判断する判断部１１と、ＥＥＰＲＯＭ等の不揮発性メモリからなる記憶部１２とを具備している。また、制御部７は点灯回路部６により所定の点検時間以上強制的にランプ２を点灯させて２次電池１の点検を行う点検機能と、２次電池１の充電状態を常時監視する監視機能とを有している。すなわち、本実施形態では制御部７で点検手段並びに監視手段を構成し、判断部１１で異常検出手段を構成している。なお、表示灯１３は発光ダイオードからなり、判断部１１により駆動されて発光する。 The control unit 7 includes a microcomputer having a timer function as a main component, and includes a charge detection unit 8 that detects the presence or absence of a charging current flowing from the charging unit 5 to the secondary battery 1, and a voltage of the secondary battery 1 (hereinafter, “ A voltage detection unit 9 for detecting the battery voltage), a lighting detection unit 10 for measuring the current (lamp current) flowing from the lighting circuit unit 6 to the lamp 2 and detecting whether the lamp 2 is lit or not, and each detection A determination unit 11 that comprehensively determines abnormality of the secondary battery 1 and the lamp 2 from the detection results of the units 8, 9, and 10 and a storage unit 12 that includes a nonvolatile memory such as an EEPROM are provided. In addition, the control unit 7 forcibly turns on the lamp 2 for a predetermined inspection time by the lighting circuit unit 6 to inspect the secondary battery 1 and a monitoring function to constantly monitor the charging state of the secondary battery 1. And have. That is, in this embodiment, the control unit 7 constitutes an inspection unit and a monitoring unit, and the determination unit 11 constitutes an abnormality detection unit. The indicator lamp 13 is formed of a light emitting diode and is driven by the determination unit 11 to emit light.

商用電源ＡＣから電力供給を受けているとき（常時）には、充電部５により２次電池１が充電されるとともに、制御部７によりスイッチ素子Ｑがオフされてランプ２を消灯させているが、停電により商用電源ＡＣからの電力供給が停止したとき（非常時）には、充電検出部８にて充電電流が検出されなくなることで停電が検知され、制御部７によりスイッチ素子Ｑがオンされて２次電池１から点灯回路部６への電力供給が可能となってランプ２を点灯させるものである。そして、復電により商用電源ＡＣからの電力供給が再開されれば、充電検出部８にて充電電流が検出されることで復電が検知され、制御部７によりスイッチ素子Ｑがオフされて２次電池１から点灯回路部６への電力供給が停止してランプ２を消灯させる。 When power is supplied from the commercial power supply AC (always), the secondary battery 1 is charged by the charging unit 5 and the switch element Q is turned off by the control unit 7 to turn off the lamp 2. When the power supply from the commercial power supply AC is stopped due to a power failure (emergency), the charge detection unit 8 no longer detects the charging current, and the control unit 7 turns on the switch element Q. Thus, power can be supplied from the secondary battery 1 to the lighting circuit section 6 to light the lamp 2. When the power supply from the commercial power supply AC is resumed due to the power recovery, the power detection is detected by the charge detection unit 8 to detect the power recovery, and the switch element Q is turned off by the control unit 7. The power supply from the secondary battery 1 to the lighting circuit unit 6 is stopped, and the lamp 2 is turned off.

本実施形態における制御部の動作を図２のフローチャートを参照して説明する。本実施形態の特徴は、短時間（例えば３秒）の停電が発生した時には充電時間カウントを継続もしくは点検可能状態を維持することである。フローチャートの＃は処理ステップの番号を意味する。 The operation of the control unit in this embodiment will be described with reference to the flowchart of FIG. A feature of this embodiment is that the charging time count is continued or maintained in an inspectable state when a power failure occurs for a short time (for example, 3 seconds). # In the flowchart means a process step number.

制御部７は、充電検出部８によって充電電流の有無を検出し、２次電池１の充電時間をカウントしている（＃１０，＃２０）。商用電源ＡＣの停電を検出すると（＃３０）、復電してからの充電時間カウント値をＥＥＰＲＯＭ等の不揮発性メモリからなる記憶部１２に記憶させて（＃４０）、充電時間カウント値をリセットして（＃４１）、スイッチ素子Ｑをオンして２次電池１からの電源供給でランプ２を非常点灯させる（＃５０）。なお、停電時の制御部７の動作電源は２次電池１から供給する。 The control unit 7 detects the presence or absence of a charging current by the charge detection unit 8 and counts the charging time of the secondary battery 1 (# 10, # 20). When a power failure of the commercial power supply AC is detected (# 30), the charging time count value after power recovery is stored in the storage unit 12 made of a nonvolatile memory such as EEPROM (# 40), and the charging time count value is reset. Then (# 41), the switch element Q is turned on and the lamp 2 is turned on by power supply from the secondary battery 1 (# 50). In addition, the operating power supply of the control part 7 at the time of a power failure is supplied from the secondary battery 1. FIG.

ここで、商用電源ＡＣが復電すると（＃６０）、停電した時間が短時間であるかを判断し（＃７０）、短時間であれば記憶部１２に記憶させた停電発生前の充電時間カウント値を読み出し（＃７１）、そこから継続して充電時間をカウントし、短時間でなければ復電した時点からの充電時間を初期値（＃４１でリセットした値）からカウントし直す。停電した時間が短時間であるかの判断については、図３に示すように、連続した停電時間（Ｔａ）が所定時間以内（例えば３秒以内）であるか否か、または累積停電時間（Ｔｂ１＋Ｔｂ２＋Ｔｂ３）が所定時間以内であるか否か、いずれの判定方法であっても良い。 Here, when the commercial power supply AC recovers (# 60), it is determined whether the power failure time is short (# 70), and if it is short time, the charging time before the power failure stored in the storage unit 12 is determined. The count value is read out (# 71), and the charging time is continuously counted from the count value. If the charging time is not short, the charging time from the time of power recovery is counted again from the initial value (the value reset at # 41). As shown in FIG. 3, whether or not the power failure time is a short time is determined as to whether the continuous power failure time (Ta) is within a predetermined time (for example, within 3 seconds) or the cumulative power failure time (Tb1 + Tb2 + Tb3). ) Is within a predetermined time, and any determination method may be used.

制御部７は点検スイッチ３の状態を監視しており、商用電源ＡＣが停電していない常時において点検スイッチ３が操作されたことを検出すると、その時点までの充電時間が所定充電時間を超えているかを判断し、超えていればスイッチ素子Ｑをオンして点検処理を行い、超えていなければ点検処理を行わない（＃８０，＃９０）。 When the control unit 7 monitors the state of the inspection switch 3 and detects that the inspection switch 3 is operated at any time when the commercial power source AC is not interrupted, the charging time up to that point exceeds the predetermined charging time. If it exceeds, the switch element Q is turned on to perform the inspection process, and if not, the inspection process is not performed (# 80, # 90).

本実施形態では、図４に示すように、所定充電時間到達前に短時間の停電が起こっても、充電時間を継続してカウントするので、例えば瞬時停電や、点検スイッチやブレーカー等の誤操作による停電状態が起こった場合は再び初期値から所定の充電時間が経過するのを待たなくても点検が出来るようになる。また、所定充電時間到達後に短時間の停電が起こった場合も、点検可能な状態を継続出来る。 In this embodiment, as shown in FIG. 4, even if a short interruption occurs before reaching the predetermined charging time, the charging time is continuously counted. Therefore, for example, due to an instantaneous interruption or an erroneous operation such as an inspection switch or a breaker. If a power failure occurs, the inspection can be performed without waiting for a predetermined charging time to elapse from the initial value. Moreover, even if a short-time power failure occurs after the predetermined charging time is reached, it is possible to continue the checkable state.

図５は本実施形態の一変形例の構成を示す。この構成例は、特願２００２−２７９７６０の実施形態７に記載されているように、複数の照明装置Ａｉ（ｉ＝１，２，…，ｎ）と、各照明装置との間で通信線Ｌを介してデータの授受を行う制御装置Ｂとで構成される非常灯あるいは誘導灯の照明システムである。この照明システムにおいても、点検要求のトリガーが点検スイッチ３からの信号に代えて、制御装置Ｂからの信号に変わるだけなので、同様の効果がある。 FIG. 5 shows a configuration of a modification of the present embodiment. In this configuration example, as described in Embodiment 7 of Japanese Patent Application No. 2002-279760, a communication line L between a plurality of lighting devices Ai (i = 1, 2,..., N) and each lighting device. This is an emergency light or guide light illumination system configured with a control device B that transmits and receives data via the control device B. This lighting system also has the same effect because the inspection request trigger is changed to the signal from the control device B instead of the signal from the inspection switch 3.

図５の照明装置は、点検スイッチ３及び表示灯１３を具備しない点と、通信線Ｌを介してデータの授受を行うための通信部１５並びに通信のためのアドレスを設定するアドレス設定部１６とを具備する点とを除けば、図１の照明装置と共通の構成を備えている。 The lighting device of FIG. 5 does not include the inspection switch 3 and the indicator lamp 13, the communication unit 15 for transmitting and receiving data via the communication line L, and the address setting unit 16 for setting an address for communication. 1 is provided in common with the illumination device of FIG.

アドレス設定部１６はディップスイッチなどで構成されており、各照明装置Ａｉ（ｉ＝１，２，…，ｎ）に固有のアドレスの他に複数の照明装置からなるグループを特定するためのグループ番号も設定可能であって、照明システムの施工時にアドレス設定が行われる。 The address setting unit 16 is configured by a dip switch or the like, and a group number for specifying a group of a plurality of lighting devices in addition to an address unique to each lighting device Ai (i = 1, 2,..., N). Can also be set, and addresses are set when the lighting system is constructed.

制御装置Ｂは、通信線Ｌを介して照明装置Ａｉ（ｉ＝１，２，…，ｎ）との間でデータを授受する通信手段やマイクロコンピュータからなる制御手段、その他にＥＥＰＲＯＭなどからなる不揮発性のメモリ等を備えている。但し、このような制御装置Ｂは従来周知の技術で実現可能であるから詳細な構成については図示並びに説明を省略する。 The control device B is a non-volatile memory composed of a communication means that exchanges data with the illumination device Ai (i = 1, 2,..., N) via the communication line L, a control means that includes a microcomputer, and an EEPROM. Memory etc. However, since such a control device B can be realized by a conventionally well-known technique, illustration and description of a detailed configuration are omitted.

本実施形態においては、制御装置Ｂが各照明装置Ａｉの固有アドレスｉを指定して定期的に（例えば、３箇月に１回）点検開始のコマンドデータを順次送信し、このコマンドデータを受信した照明装置Ａｉでは、制御部７が通信部１５で受信したコマンドデータを解釈して点検処理を開始し、スイッチ素子Ｑをオンして２次電池１からの電力供給でランプ２を点灯させ、個々の照明装置Ａｉ毎に制御装置Ｂからの指令で定期点検を行う。また、各照明装置Ａｉでは、３箇月に１回行われる定期点検とは別に２次電池１の状態を常時監視しており、判断部１１では定期点検の点検結果と監視結果を総合的に判断して２次電池１並びにランプ２の異常の有無を判断し、優先順位の高い結果を選択して制御装置Ｂに送信している。したがって、点検作業を行う者は各照明装置Ａｉの設置場所まで赴いて点検を行わなくても制御装置Ｂによってそれぞれの照明装置Ａｉの点検結果を把握することができて点検作業の省力化が図れるものである。 In the present embodiment, the control device B designates the unique address i of each lighting device Ai, and regularly transmits command data for starting inspection periodically (for example, once every three months), and receives this command data. In the lighting device Ai, the control unit 7 interprets the command data received by the communication unit 15 and starts an inspection process, turns on the switch element Q and turns on the lamp 2 by supplying power from the secondary battery 1. Periodic inspection is performed in accordance with a command from the control device B for each lighting device Ai. In addition, each lighting device Ai constantly monitors the state of the secondary battery 1 separately from the periodic inspection performed once every three months, and the determination unit 11 comprehensively determines the inspection result and the monitoring result of the periodic inspection. Then, the presence or absence of abnormality in the secondary battery 1 and the lamp 2 is determined, and a result having a high priority is selected and transmitted to the control device B. Therefore, the person who performs the inspection work can grasp the inspection result of each lighting device Ai by the control device B without going to the installation place of each lighting device Ai and performing the inspection, thereby saving labor of the inspection work. Is.

図６は実施形態１の他の変形例の構成を示す。この構成例は、特願２００２−２７９７６０の実施形態８に記載されているように、常時及び非常時ともにランプを点灯させるタイプの非常灯あるいは誘導灯として構成されている。すなわち、図６に示すように、電源回路部４の出力を充電部５だけでなく点灯回路部６にも入力し、常時においても商用電源ＡＣからの電力供給でランプ２を点灯させ、非常時には制御部７によりスイッチ素子Ｑをオンして２次電池１からの電力供給でランプ２を点灯させるものである。なお、本実施形態では常時においてもランプ２を点灯させるから、常時の監視項目（＃１０の常用状態処理）にランプ２の点灯、不点灯の検出も追加する必要がある。
また、これらの図５、図６の構成は以下に説明するいずれの実施形態においても同様に実施できる。 FIG. 6 shows a configuration of another modification of the first embodiment. As described in the eighth embodiment of Japanese Patent Application No. 2002-279760, this configuration example is configured as an emergency light or a guide light of a type that lights the lamp at all times and in an emergency. That is, as shown in FIG. 6, the output of the power supply circuit unit 4 is input not only to the charging unit 5 but also to the lighting circuit unit 6, and the lamp 2 is lit by power supply from the commercial power supply AC at all times. The switch element Q is turned on by the control unit 7 and the lamp 2 is turned on by supplying power from the secondary battery 1. In the present embodiment, since the lamp 2 is lit at all times, it is necessary to add detection of lighting / non-lighting of the lamp 2 to the constantly monitored items (normal state processing of # 10).
5 and 6 can be similarly implemented in any of the embodiments described below.

（実施形態２）
本実施形態における制御部の動作を図７のフローに示す。本実施形態の特徴は、２次電池の所定の充電時間が経過する前に停電が発生したときに、それまでの充電時間に応じて放電時の判定時間を変化させることにある。なお、本実施形態における照明装置の構成は実施形態１と同じであるから図示並びに説明は省略する。 (Embodiment 2)
The operation of the control unit in this embodiment is shown in the flow of FIG. The feature of this embodiment is that when a power failure occurs before a predetermined charging time of the secondary battery elapses, the determination time at the time of discharging is changed according to the charging time up to that time. In addition, since the structure of the illuminating device in this embodiment is the same as Embodiment 1, illustration and description are abbreviate | omitted.

特願２００２−２７９７６０では所定充電時間（例えば２４時間）が経過した後で点検可能状態となり、点検可能状態において点検要求があると、規定時間（例えば２０分間）放電し点検を行う（図８）。これに対して本実施形態では、所定充電時間が経過していなくても、点検要求があれば２次電池を放電させ、点検を行う。例えば、誘導灯において、充電時間が１８時間で点検要求が来ると、本来必要である充電時間の７５％しか経過していないので、例えば規定時間の７５％に相当する１５分間の放電によって判定を行う（図９）。なお、電池電圧と時間の関係を示すグラフにおいて、横軸の単位［ｈ］は時間、単位［ｍ］は分を意味する。以下の各実施形態においても同様である。 In Japanese Patent Application No. 2002-279760, after a predetermined charging time (for example, 24 hours) elapses, the inspection becomes possible, and when there is an inspection request in the inspectable state, discharge is performed for a specified time (for example, 20 minutes) (FIG. 8). . On the other hand, in this embodiment, even if the predetermined charging time has not elapsed, if there is an inspection request, the secondary battery is discharged and the inspection is performed. For example, in the case of a guide light, when an inspection request is made at a charging time of 18 hours, only 75% of the originally required charging time has elapsed, so for example, the determination is made by discharging for 15 minutes corresponding to 75% of the specified time. Perform (FIG. 9). In the graph showing the relationship between battery voltage and time, the unit [h] on the horizontal axis means time, and the unit [m] means minute. The same applies to the following embodiments.

判定時間の算出法は、図１０に示すように、所定充電時間（満充電に要する充電時間）に対して充電時間が短くなれば、その分、判定時間を規定時間に対して短くする。図１０では、充電時間に比例して判定時間を変化させる例を示しているが、変化の度合いは比例関係に限定されるものではなく、例えば２次電池の充放電効率によって傾きや切片を変更したり、１次関数以外の計算式であっても構わない。これは、以下に説明する図１４、図１７、図２０においても同様である。 As shown in FIG. 10, the determination time is calculated by shortening the determination time relative to the specified time if the charge time is shorter than the predetermined charge time (charge time required for full charge). Although FIG. 10 shows an example in which the determination time is changed in proportion to the charging time, the degree of change is not limited to the proportional relationship, and for example, the slope or intercept is changed depending on the charge / discharge efficiency of the secondary battery. Or a calculation formula other than a linear function. This 14 discussed below, FIG. 17 is the same in FIG. 20.

本実施形態における制御部の動作を図７のフローチャートを参照して説明する。制御部は、常用状態処理において、充電検出部によって充電電流の有無を検出し、２次電池の充電時間をカウントしている（＃１０，＃２０）。ここで点検要求があれば（＃８０）、その時点までの充電時間をもとに制御部で判定時間を算出し（＃８５）、点検の判定時間を変えて、スイッチ素子Ｑをオンして点検処理を行う（＃９０）。 The operation of the control unit in this embodiment will be described with reference to the flowchart of FIG.

本構成例における制御部の動作を図１１のフローに示す。本構成例の特徴は、２次電池が所定充電時間経過した状態で停電が発生したとき、停電によって放電した時間に応じて、復電後の点検可能状態になるまでの充電時間を変化させることにある。なお、本構成例における照明装置の構成も実施形態１と同じであるから、図示並びに説明は省略する。 ( Related configuration 1 )
The operation of the control unit in this configuration example is shown in the flow of FIG. The feature of this configuration example is that, when a power failure occurs when a predetermined charging time has elapsed for the secondary battery, the charging time until the inspection is possible after power recovery is changed according to the time discharged by the power failure. It is in. In addition, since the structure of the illuminating device in this structural example is also the same as Embodiment 1, illustration and description are abbreviate | omitted.

特願２００２−２７９７６０では所定時間充電された状態から停電して復電すると、再び所定充電時間（例えば２４時間）経過しなくては、点検可能状態にならなかった（図１２）。これに対して本構成例では、所定時間充電された状態（満充電状態）から停電して復電すると、放電時間から判断して、あとどれだけ充電すれば所定充電時間経過した状態と同等の電気量になるか（以下「補充電時間」とする）を算出し、その分だけ充電すれば点検可能状態になる。例えば誘導灯において、所定時間充電された状態から１５分間停電して復電すると、２次電池の放電による点検の規定時間２０分に対して７５％相当しか放電していないので、所定の充電時間の７５％である１８時間充電すれば点検可能状態となる（図１３）。補充電時間の算出方法は、規定時間に対して放電した時間（停電時間）が短ければその分補充電時間を所定時間に対して短くする（図１４）。 In Japanese Patent Application No. 2002-279760, when a power failure occurred after the power was charged for a predetermined time and power was restored, the test could not be performed until a predetermined charge time (for example, 24 hours) had passed again (FIG. 12). On the other hand, in this configuration example , when power is restored from a state charged for a predetermined time (fully charged state) and power is restored, it is determined from the discharge time, and how much more charging is required is equivalent to the state after the predetermined charging time has elapsed. If the amount of electricity is reached (hereinafter referred to as “supplementary charging time”) and charging is performed by that amount, inspection is possible. For example, in a guide light, if a power failure occurs for 15 minutes from a state where it is charged for a predetermined time and power is restored, only 75% of the specified time for inspection by discharging of the secondary battery is discharged, which is equivalent to 75%. If it is charged for 18 hours, which is 75% of the above, the inspection is possible (FIG. 13). In the method of calculating the auxiliary charging time, if the discharging time (power failure time) is shorter than the specified time, the auxiliary charging time is shortened by a corresponding amount (FIG. 14).

本構成例における制御部の動作を図１１のフローチャートを参照して説明する。制御部は、常用状態処理において、充電検出部によって充電電流の有無を検出し、２次電池の充電時間をカウントしている（＃１０，＃２０）。ここで商用電源ＡＣが停電すると（＃３０）、所定時間充電されていたかを判断し（＃４２）、充電されていれば、放電時間をカウントして記憶部に保存する処理を開始し（＃４３）、スイッチ素子Ｑをオンして２次電池からの電源供給でランプを非常点灯させる（＃５０）。＃４２で所定時間充電されていなければ、放電時間カウントをせずに非常点灯させる。商用電源ＡＣが復電すると（＃６０）、放電時間カウント値を記憶部から読み出し、制御部で図１４の演算を行い、必要な補充電時間を算出する。補充電時間が経過すれば、点検可能状態となる。なお、放電時間カウントをせずに非常点灯させた場合は、放電時間＝規定時間（２０分間）とみなして、補充電時間＝所定時間（２４時間）とすれば良い。 The operation of the control unit in this configuration example will be described with reference to the flowchart of FIG. In the normal state process, the control unit detects the presence or absence of a charging current by the charge detection unit, and counts the charging time of the secondary battery (# 10, # 20). Here, when the commercial power source AC is out of power (# 30), it is determined whether it has been charged for a predetermined time (# 42). If it is charged, a process of counting the discharge time and storing it in the storage unit is started (# 43) The switch element Q is turned on and the lamp is turned on by power supply from the secondary battery (# 50). If the battery has not been charged for a predetermined time in # 42, the emergency lighting is performed without counting the discharge time. When the commercial power supply AC recovers (# 60), the discharge time count value is read from the storage unit, and the control unit performs the calculation of FIG. 14 to calculate the necessary supplementary charging time. When the auxiliary charging time has elapsed, the inspection is possible. When the emergency lighting is performed without counting the discharge time, it is considered that the discharge time is equal to the specified time (20 minutes), and the auxiliary charge time is equal to the predetermined time (24 hours).

このように本構成例では、所定充電時間経過した状態から停電すると、放電時間に応じて補充電時間を設定するので、復電後に点検可能状態になる迄の時間を短縮することが出来る。 As described above, in this configuration example , when a power failure occurs after a predetermined charging time has elapsed, the supplementary charging time is set according to the discharging time, so the time until the inspection can be performed after the power recovery can be shortened.

（関連する構成２）
本構成例における制御部の動作を図１５のフローに示す。本構成例の特徴は、所定時間充電されてない状態で停電したとき、停電になるまでの充電時間と停電による放電時間に応じて、復電後の補充電時間を決めることにある。なお、本構成例における照明装置の構成も実施形態１と同じであるから、図示並びに説明は省略する。 ( Related configuration 2 )
The operation of the control unit in this configuration example is shown in the flow of FIG. A feature of this configuration example is that, when a power failure occurs in a state where the battery is not charged for a predetermined time, a supplementary charging time after power recovery is determined according to a charging time until the power failure occurs and a discharging time due to the power failure. In addition, since the structure of the illuminating device in this structural example is also the same as Embodiment 1, illustration and description are abbreviate | omitted.

関連する構成１では、放電時間のみから補充電時間を算出するため、所定時間充電されてない状態で停電すると補充電時間を算出できなかった。これに対して本構成例では、所定時間充電されていない状態で停電しても補充電時間を算出できる。例えば誘導灯において、充電時間が１８時間で５分間停電すると、充電時間が所定充電時間２４時間に対して７５％、放電時間が規定時間２０分に対して２５％相当であるので、７５％−２５％＝５０％に相当する１２時間充電すれば点検可能状態となる（図１６）。補充電時間の算出法は、充電時間カウント値に基づいて算出される充電電気量から、放電時間カウント値に基づいて算出される放電電気量を差し引いて、補充電時間を決める。完全放電状態であれば補充電時間は所定時間となり、満充電状態に近いほど補充電時間は短くなる（図１７）。 In the related configuration 1 , since the auxiliary charging time is calculated from only the discharging time, the auxiliary charging time cannot be calculated if a power failure occurs while the battery is not charged for a predetermined time. On the other hand, in this configuration example , the auxiliary charging time can be calculated even if a power failure occurs in a state where the charging is not performed for a predetermined time. For example, in a guide light, if a power failure occurs for 18 minutes with a charging time of 18 hours, the charging time is 75% for a predetermined charging time of 24 hours, and the discharging time is 25% for a specified time of 20 minutes. If the battery is charged for 12 hours corresponding to 25% = 50%, the inspection is possible (FIG. 16). In the method for calculating the auxiliary charging time, the auxiliary charging time is determined by subtracting the discharging electric amount calculated based on the discharging time count value from the charging electric amount calculated based on the charging time count value. If the battery is completely discharged, the auxiliary charging time is a predetermined time. The closer to the fully charged state, the shorter the auxiliary charging time (FIG. 17).

本構成例における制御部の動作を図１５のフローチャートを参照して説明する。制御部は、常用状態処理において、充電検出部によって充電電流の有無を検出し、２次電池の充電時間をカウントして記憶部に記憶している（＃１０，＃２１）。ここで商用電源ＡＣが停電すると（＃３０）、放電時間をカウントして記憶部に保存する処理を開始し（＃４３）、スイッチ素子Ｑをオンして２次電池からの電源供給でランプを非常点灯させる（＃５０）。商用電源ＡＣが復電すると（＃６０）、記憶部から充電時間カウント値と放電時間カウント値を読み出し、制御部で演算を行い補充電時間を算出する（＃７３）。補充電時間が経過すれば、点検可能状態となる。 The operation of the control unit in this configuration example will be described with reference to the flowchart of FIG. In the normal state process, the control unit detects the presence or absence of a charging current by the charge detection unit, counts the charging time of the secondary battery, and stores it in the storage unit (# 10, # 21). Here, when the commercial power supply AC fails (# 30), the discharge time is counted and stored in the storage unit (# 43), the switch element Q is turned on, and the lamp is turned on by supplying power from the secondary battery. Turn on the emergency light (# 50). When the commercial power supply AC recovers (# 60), the charging time count value and the discharging time count value are read from the storage unit, and the controller calculates the auxiliary charging time (# 73). When the auxiliary charging time has elapsed, the inspection is possible.

このように本構成例では、停電になるまでの充電時間と停電後に放電した時間によって補充電時間を設定するので、所定充電時間経過してない状態で停電しても、復電後に点検可能状態になる迄の時間を短縮することが出来る。 In this way, in this configuration example , the auxiliary charging time is set according to the charging time until a power failure and the time discharged after the power failure, so even if a power failure occurs when the predetermined charging time has not elapsed, it can be inspected after power recovery Time to become can be shortened.

なお、関連する構成１または２において、補充電時間が経過する前に、図１１または図１５の＃８０で点検スイッチの操作が検出されたときは、充電時間が所定充電時間を超えていないと判断し、点検処理を行わない。また、補充電時間の経過後に、＃８０で点検スイッチの操作が検出されたときは、充電時間が所定充電時間を超えていると判断し、点検処理を行う（＃９０）。 In the related configuration 1 or 2 , if the operation of the inspection switch is detected in # 80 of FIG. 11 or FIG. 15 before the supplementary charging time has elapsed, the charging time does not exceed the predetermined charging time. Judgment and inspection process is not performed. If the operation of the inspection switch is detected in # 80 after the auxiliary charging time has elapsed, it is determined that the charging time has exceeded the predetermined charging time, and inspection processing is performed (# 90).

（実施形態３）
本実施形態における制御部の動作を図１８のフローに示す。本実施形態の特徴は、２次電池が所定充電時間経過した状態で停電が発生したのちに復電したとき、停電による放電時間と復電後の充電時間から、所定充電時間が経過する前に点検要求が来たときの判定時間を決めることにある。なお、本実施形態における照明装置の構成も実施形態１と同じであるから図示並びに説明は省略する。 (Embodiment 3 )
The operation of the control unit in this embodiment is shown in the flow of FIG. The feature of this embodiment is that when the secondary battery is restored after a power failure occurs in a state where the predetermined charging time has elapsed, the discharge time due to the power failure and the charging time after the power recovery are before the predetermined charging time elapses. It is to determine the judgment time when an inspection request comes. In addition, since the structure of the illuminating device in this embodiment is also the same as Embodiment 1, illustration and description are abbreviate | omitted.

実施形態２では、充電時間のみから判定時間を算出するため、例えば所定充電時間経過した状態で停電になり、その後復電した充電中に点検要求が来ると、２次電池の電気量が十分あるにも関わらず判定時間を短く設定してしまうことがある。これに対して本実施形態では、所定充電時間経過した状態で発生した放電時間もカウントするので、放電時間と充電時間を考慮して判定時間を算出できる。例えば誘導灯において、所定時間充電された状態から１０分間の停電があり、復電後６時間経過した状態で点検要求が来ると、放電時間が規定時間２０分に対して５０％相当、充電時間が所定充電時間２４時間に対して２５％であるので、規定時間に対して１００％−５０％＋２５％＝７５％に相当する１５分の放電によって判定を行う（図１９）。判定時間の算出法は、所定充電時間経過した状態からの放電時間のカウント値から、復電後の充電時間のカウント値を差し引いて、所定充電時間経過した状態であれば判定値は規定時間となり、完全放電状態に近いほど判定時間は短くなる（図２０）。 In the second embodiment, since the determination time is calculated only from the charging time, for example, if a power failure occurs after a predetermined charging time has elapsed, and then an inspection request is received during charging after power recovery, the amount of electricity in the secondary battery is sufficient. Nevertheless, the determination time may be set short. On the other hand, in the present embodiment, since the discharge time that occurs after the predetermined charge time has elapsed is also counted, the determination time can be calculated in consideration of the discharge time and the charge time. For example, in a guide light, if there is a power outage for 10 minutes after being charged for a predetermined time and an inspection request comes in after 6 hours have passed since power recovery, the discharge time is equivalent to 50% of the specified time of 20 minutes. Is 25% with respect to the predetermined charging time of 24 hours, so the determination is made by discharging for 15 minutes corresponding to 100% -50% + 25% = 75% with respect to the specified time (FIG. 19). The determination time is calculated by subtracting the count value of the charging time after power recovery from the count value of the discharging time after the predetermined charging time has elapsed, and if the predetermined charging time has elapsed, the determination value becomes the specified time. The determination time becomes shorter as the state is completely discharged (FIG. 20).

本実施形態における制御部の動作を図１８のフローチャートを参照して説明する。制御部は、常用状態処理において、充電検出部によって充電電流の有無を検出し、２次電池の充電時間をカウントして記憶部に保存している（＃１０，＃２１）。ここで商用電源ＡＣが停電すると（＃３０）、＃２１で保存された充電時間カウント値を読み出して、所定時間充電されていたかを判断し（＃４２）、充電されていれば、放電時間をカウントして記憶部に保存する処理を開始させ（＃４３）、スイッチ素子Ｑをオンして２次電池からの電源供給でランプを非常点灯させる（＃５０）。＃４２で所定時間充電されていないと判断されれば、放電時間はカウントをせずに非常点灯させる。商用電源ＡＣが復電すると（＃６０）、充電時間を初期値からカウントし直す。商用電源ＡＣが停電していない常時において点検要求があれば（＃８２）、記憶部からその時点までの充電時間カウント値と、放電時間カウント値を読み出して、制御部で点検の判定時間を算出し（＃８３）、スイッチ素子Ｑをオンして点検処理を行う（＃９０）。 The operation of the control unit in this embodiment will be described with reference to the flowchart of FIG. In the normal state process, the control unit detects the presence or absence of a charging current by the charge detection unit, counts the charging time of the secondary battery, and stores it in the storage unit (# 10, # 21). Here, when the commercial power supply AC is out of power (# 30), the charging time count value stored in # 21 is read out to determine whether it has been charged for a predetermined time (# 42). The process of counting and storing in the storage unit is started (# 43), the switch element Q is turned on, and the lamp is lit up by power supply from the secondary battery (# 50). If it is determined in # 42 that the battery has not been charged for a predetermined time, the discharge time is not counted and the emergency light is turned on. When the commercial power supply AC recovers (# 60), the charging time is counted again from the initial value. If there is an inspection request at any time when the commercial power supply AC is not out of power (# 82), the charging time count value and the discharging time count value up to that point are read from the storage unit, and the control determination time is calculated by the control unit (# 83), the switch element Q is turned on to perform the inspection process (# 90).

このように本実施形態では、満充電状態から停電して放電した時間と、復電後に点検要求が来るまでの充電時間とに基づいて、判定時間を設定するので、点検不能な状態を少なくすることが出来る。また、所定充電時間経過した状態を基準としているので、実施形態２よりも判定精度を向上させることができ、容量低下を早期に検出することができる。 As described above, in this embodiment, since the determination time is set based on the time when the power is interrupted and discharged from the fully charged state and the charging time until the inspection request comes after the power recovery, the state where the inspection is impossible is reduced. I can do it. Moreover, since the state after the predetermined charging time has passed is used as a reference, the determination accuracy can be improved as compared with the second embodiment, and the capacity reduction can be detected at an early stage.

（実施形態４）
本実施形態における制御部の動作を図２１のフローに示す。本実施形態の特徴は、停電による放電時間と、復電してからの充電時間の組み合わせより、補充電時間及び判定時間を変えることである。なお、本実施形態における照明装置の構成も実施形態１と同じであるから図示並びに説明は省略する。 (Embodiment 4 )
The operation of the control unit in this embodiment is shown in the flow of FIG. A feature of the present embodiment is that the auxiliary charging time and the determination time are changed based on a combination of a discharging time due to a power failure and a charging time after power is restored. In addition, since the structure of the illuminating device in this embodiment is also the same as Embodiment 1, illustration and description are abbreviate | omitted.

関連する構成２および実施形態３では、充電時間と放電時間から補充電時間や判定時間を算出している。しかし、関連する構成２では、補充電中に点検要求が来ると点検が行えない。また、実施形態３では、所定時間充電されてない状態で停電すると放電時間をカウントしないので、復電後の充電時間のみから判定時間を算出し、２次電池の電気量が十分あるにも関わらず判定時間を短く設定してしまうことがある。 In the related configuration 2 and the third embodiment , the auxiliary charging time and the determination time are calculated from the charging time and the discharging time. However, in the related configuration 2 , if an inspection request is received during auxiliary charging, the inspection cannot be performed. In the third embodiment, the discharge time is not counted when a power failure occurs while the battery is not charged for a predetermined time. Therefore, the determination time is calculated only from the charge time after power recovery, and the amount of electricity of the secondary battery is sufficient. The determination time may be set short.

これに対して本実施形態では、補充電中でも放電による判定の時間を変えて点検ができ、かつ所定時間充電されていない状態で停電しても放電時間をカウントする。例えば誘導灯において、１８時間充電された状態から１０分間の停電があると、関連する構成２により７５％−５０％＝２５％となるので１８時間の補充電時間を設定する（図２２）。さらに補充電を開始してから、１２時間後に点検要求があると、実施形態３により２５％＋５０％＝７５％となるので１５分の放電によって点検を行う（図２３）。 On the other hand, in this embodiment, even during supplementary charging, inspection can be performed by changing the determination time by discharging, and the discharging time is counted even if a power failure occurs while the battery is not charged for a predetermined time. For example, in a guide light, if there is a power failure for 10 minutes from a state where it is charged for 18 hours, 75% -50% = 25% due to the related configuration 2 , so an auxiliary charging time of 18 hours is set (FIG. 22). Furthermore, if an inspection request is made 12 hours after the start of supplementary charging, it will be 25% + 50% = 75% according to the third embodiment, so inspection is performed by discharging for 15 minutes (FIG. 23).

本実施形態における制御部の動作を図２１のフローチャートを参照して説明する。制御部は、常用状態処理において、充電検出部によって充電電流の有無を検出し、２次電池の充電時間をカウントして記憶部に保存している（＃１０，＃２１）。ここで商用電源ＡＣが停電又は点検要求があると（＃３１）、記憶部から充電時間カウント値と前回の放電時間カウント値を読み出し、制御部で点検の判定時間を算出し（＃３３）、さらに放電時間をカウントして記憶部に保存する処理を開始させ（＃４３）、スイッチ素子Ｑをオンして、点検処理又は非常点灯処理を行う（＃５９）。復電すると（＃６０）、記憶部から充電時間カウント値と放電時間カウント値を読み出し、制御部で補充電時間を算出する（＃７３）。 The operation of the control unit in this embodiment will be described with reference to the flowchart of FIG. In the normal state process, the control unit detects the presence or absence of a charging current by the charge detection unit, counts the charging time of the secondary battery, and stores it in the storage unit (# 10, # 21). Here, when the commercial power source AC has a power failure or inspection request (# 31), the charging time count value and the previous discharge time count value are read from the storage unit, and the control determination time is calculated by the control unit (# 33). Further, a process of counting the discharge time and storing it in the storage unit is started (# 43), the switch element Q is turned on, and an inspection process or an emergency lighting process is performed (# 59). When power is restored (# 60), the charge time count value and the discharge time count value are read from the storage unit, and the auxiliary charge time is calculated by the control unit (# 73).

このように本実施形態では、関連する構成２、実施形態３を組み合わせることにより、常に点検可能な状態とすることができ、かつ２次電池の判定精度を向上させることができる。 As described above, in the present embodiment, by combining the related configurations 2 and 3 , it is possible to always inspect and to improve the determination accuracy of the secondary battery.
