Description

本発明の実施形態は、電力線搬送通信を行う灯火監視制御システムに関する。   Embodiments of the present invention relate to a light monitoring control system that performs power line communication.

航空灯火では、いかなる環境下でも灯火がパイロットから見えにくかったり、反対にまぶし過ぎないように、電流を一定に制御して灯器の光度を一定に保つ必要がある。そのため、灯火監視制御システムの電源としては、サイリスタスイッチングなどにより電流調整が可能である定電流調整器（以下、ＣＣＲと呼ぶ）が採用されている。   In aeronautical lighting, it is necessary to maintain a constant current and keep the luminous intensity of the lamp constant so that the lamp is not easily seen by a pilot or vice versa under any circumstances. For this reason, a constant current regulator (hereinafter, referred to as CCR) capable of adjusting current by thyristor switching or the like is used as a power supply of the lamp monitoring and control system.

また、灯火監視制御システムには、電源に通信信号を重畳させた電力線搬送通信が採用されている。電力線搬送通信とは、灯器を接続した子局と、基地局となる親局との間で、電力線搬送信号を授受する通信手法である。このような電力線搬送通信を灯火監視制御システムに採用することにより、空港内に設置された多数の灯器を、効率良く監視制御することが可能となる。   In addition, a power line carrier communication in which a communication signal is superimposed on a power supply is employed in the light monitoring and control system. Power line carrier communication is a communication method for exchanging power line carrier signals between a slave station connected to a lamp and a master station serving as a base station. By adopting such power line carrier communication in the lighting monitoring control system, it is possible to efficiently monitor and control a large number of lighting devices installed in the airport.

特開２００７−２６７０５７号公報JP 2007-267057 A

灯火監視制御システムの電源であるＣＣＲは、サイリスタスイッチングなどを組み込んでいる。そのため、ＣＣＲは一般的な商用電源に比べてノイズが多い。また近年、灯器のＬＥＤ化が進んでおり、ＬＥＤ内の電子回路からもノイズが発生する。従って、灯火監視制御システムではノイズの発生が多い。その結果、ノイズと電力線搬送信号との判別が困難になり、電力線搬送通信ができなくなるおそれがある。   The CCR, which is the power source of the light monitoring and control system, incorporates thyristor switching and the like. Therefore, the CCR has more noise than a general commercial power supply. In recent years, the use of LEDs in lighting devices has been increasing, and noise is also generated from electronic circuits in the LEDs. Therefore, a lot of noises occur in the lamp monitoring and control system. As a result, it becomes difficult to distinguish between noise and the power line carrier signal, and power line carrier communication may not be possible.

ノイズにより電力線搬送通信ができなくなった場合には、信号強度や信号判別閾値などの電力線パラメータを、適切な値に設定し直す必要がある。このとき、各子局に対してパラメータ調整用の信号を親局から一括して送ることができれば、パラメータの調整作業を効率良く行うことが可能である。   When power line carrier communication becomes impossible due to noise, it is necessary to reset power line parameters such as signal strength and signal determination threshold to appropriate values. At this time, if signals for parameter adjustment can be sent to the slave stations collectively from the master station, parameter adjustment work can be performed efficiently.

ところが、そもそも電力線パラメータの調整は、電力線搬送通信を正常に行えないからこそ要請されているのであって、電源としてＣＣＲを利用している限り、電力線搬送通信によるパラメータ調整は不可能である。そのため、現状ではメンテナンス員が子局の設置場所までいちいち移動して、電力線パラメータの調整を行っている。しかし、子局は広い空港内に多数点在しており、パラメータを調整するための労力は膨大である。その結果、調整作業の効率が低く、メンテナンスコストが高騰するという不具合が生じた。   However, adjustment of power line parameters is required only because power line carrier communication cannot be performed normally, and parameter adjustment by power line carrier communication is not possible as long as a CCR is used as a power source. Therefore, at present, the maintenance staff moves to the installation location of the slave station one by one to adjust the power line parameters. However, many slave stations are scattered in a large airport, and the effort to adjust the parameters is enormous. As a result, there has been a problem that the efficiency of the adjustment work is low and the maintenance cost rises.

本実施形態は、上記問題点を解決するために提案されたものであり、ノイズの発生に伴って電力線パラメータの調整が必要な場合でも、電力線搬送通信を利用することが可能な灯火監視制御システムを提供することを課題とする。   The present embodiment has been proposed to solve the above-described problem, and even when adjustment of power line parameters is necessary due to generation of noise, a light monitoring control system capable of using power line carrier communication. The task is to provide

（第１の実施形態）
［構成］
以下、本発明の第１の実施形態の構成について、図１を参照して具体的に説明する。図１に示すように、第１の実施形態に係る灯火監視制御システム１０には、監視制御装置１と、ＣＣＲ２と、予備電源３と、出力装置４と、親局５と、子局６と、ＬＥＤ灯器９と、が設けられている。なお、図１には便宜的にＬＥＤ灯器９及び子局６を１つだけ示したが、実際には、広大な空港に多数点在している。 (First embodiment)
[Constitution]
Hereinafter, the configuration of the first exemplary embodiment of the present invention will be specifically described with reference to FIG. As shown in FIG. 1, the lighting monitoring control system 10 according to the first embodiment includes a monitoring control device 1, a CCR 2, a standby power supply 3, an output device 4, a master station 5, and a slave station 6. , LED lighting device 9. Although only one LED lamp 9 and one slave station 6 are shown in FIG. 1 for convenience, a large number of airports are actually scattered.

監視制御装置１は、電力線搬送通信を用いて灯器９の監視制御を行う装置である。また、監視制御装置１は、メンテナンス員から入力操作を受けるなどして電力線パラメータの設定を行うようになっている。ＣＣＲ２は、灯火監視制御システム１０の主電源であり、サイリスタスイッチングによって電流調整が可能な電源である。   The monitoring control device 1 is a device that performs monitoring control of the lamp 9 using power line carrier communication. Further, the monitoring control device 1 is configured to set power line parameters by receiving an input operation from a maintenance person or the like. The CCR 2 is a main power supply of the light monitoring and control system 10, and is a power supply capable of adjusting current by thyristor switching.

これに対して予備電源３は、サイリスタスイッチングを行わない、つまり電流調整を行わない電源である。予備電源３の電流値は、パラメータ設定用として予め決められた値に設定されている。出力装置４は、通常時はＣＣＲ２を電源とし、電力線パラメータの設定時にのみ電源をＣＣＲ２から予備電源３に切り替える装置である。   On the other hand, the standby power supply 3 is a power supply that does not perform thyristor switching, that is, does not perform current adjustment. The current value of the backup power supply 3 is set to a value predetermined for parameter setting. The output device 4 is a device that normally uses the CCR 2 as a power source and switches the power source from the CCR 2 to the standby power source 3 only when setting power line parameters.

灯火監視制御システム１０には、互いに電力線搬送信号を授受する親局５及び子局６が設けられている。親局５は監視制御装置１の近傍に設置されており、子局６は親局５から離れた位置に点在して多数配置されている。各子局６にはＬＥＤ灯器９が接続されている。親局５及び子局６は、ＣＣＲ２又は予備電源３からの電源に重畳させて電力線搬送通信を行うようになっている。   The light monitoring and control system 10 is provided with a master station 5 and a slave station 6 that exchange power line carrier signals with each other. The master station 5 is installed in the vicinity of the monitoring and control device 1, and a number of slave stations 6 are scattered at positions distant from the master station 5. An LED lamp 9 is connected to each slave station 6. The master station 5 and the slave station 6 perform power line carrier communication by superimposing the power on the power from the CCR 2 or the standby power supply 3.

親局５は電力線搬送信号の注入及び抽出装置を組み込んだ基地局である。子局６は、その内部に、ＬＥＤ灯器９を消灯するための短絡回路７と、電力線搬送信号の注入及び抽出回路８が設けられている。短絡回路７は、予め設定された電流値を検知することをトリガーとして短絡し、ＬＥＤ灯器９を消灯する回路である。短絡回路７においてトリガーとして検知される電流値は、予備電源３が出力するパラメータ設定専用の電流値である。   The master station 5 is a base station incorporating a power line carrier signal injection and extraction device. The slave station 6 is provided therein with a short circuit 7 for turning off the LED lamp 9 and a power line carrier signal injection and extraction circuit 8. The short-circuit 7 is a circuit that short-circuits by detecting a preset current value as a trigger and turns off the LED lamp 9. The current value detected as a trigger in the short circuit 7 is a current value output from the standby power supply 3 and dedicated to parameter setting.

（作用と効果）
ノイズなどにより電力線搬送通信が正常に行われなくなった場合、電力線パラメータの変更処理を行い、電力線搬送通信の正常化を図る必要がある。電力線パラメータの変更処理のフローを図２に示す。灯火監視制御システム１０において、ノイズの発生によって電力線搬送通信が正常に行えないとメンテナンス員が判断すると、電力線パラメータを適切な値に調整すべく、監視制御装置１は電力線パラメータの変更を開始する（ＳＴ０１）。 (Action and effect)
When power line carrier communication is not normally performed due to noise or the like, it is necessary to perform power line parameter change processing to normalize the power line carrier communication. FIG. 2 shows a flow of the power line parameter changing process. In the light monitoring and control system 10, when the maintenance staff determines that the power line communication cannot be performed normally due to the occurrence of noise, the monitoring and control device 1 starts changing the power line parameters in order to adjust the power line parameters to appropriate values ( ST01).

電力線パラメータの変更時には、まず予備電源３が起動する（ＳＴ０２）。その後、出力装置４が、ＣＣＲ２を主回路から切り離し、予備電源３を主回路に接続する。すなわち、灯火監視制御システム１０では、出力装置４にて主電源であるＣＣＲ２から予備電源３に切り替える（ＳＴ０３）。   When changing the power line parameters, first, the standby power supply 3 is activated (ST02). Thereafter, the output device 4 disconnects the CCR 2 from the main circuit, and connects the standby power supply 3 to the main circuit. That is, in the lamp monitoring and control system 10, the output device 4 switches from the main power supply CCR2 to the standby power supply 3 (ST03).

予備電源３は、サイリスタスイッチングを行わない（電流調整を行わない）電源なので、サイリスタスイッチングに起因するノイズ発生が無い。つまり、第１の実施形態では、電力線パラメータの変更時に、ノイズの無い予備電源３を電源として用いることができ、ノイズの主要因であるＣＣＲ２の影響を無くし、ＣＣＲ２側のノイズを排除することが可能である。   Since the standby power supply 3 is a power supply that does not perform thyristor switching (does not perform current adjustment), there is no generation of noise due to thyristor switching. That is, in the first embodiment, when the power line parameters are changed, the standby power supply 3 having no noise can be used as the power supply, and the influence of the CCR 2 which is a main factor of the noise can be eliminated, and the noise on the CCR 2 side can be eliminated. It is possible.

また、予備電源３はパラメータ設定用の電流値などを出力する（ＳＴ０４）。そのため、子局６ではパラメータ設定用の電流値を検出し（ＳＴ０５）、これが消灯制御への移行トリガーとなって子局６内の短絡回路７は短絡して、ＬＥＤ灯器９を消灯することができる（ＳＴ０６）。従って、第１の実施形態では、予備電源３からの電流を受けた短絡回路７がＬＥＤ灯器９を自動的に消灯することができ、子局６に対してパラメータ変更処理の開始を伝えることができる。   Further, the standby power supply 3 outputs a current value for parameter setting and the like (ST04). Therefore, the slave station 6 detects a current value for parameter setting (ST05), and this triggers a transition to the light-off control, whereby the short circuit 7 in the slave station 6 is short-circuited and the LED lamp 9 is turned off. (ST06). Therefore, in the first embodiment, the short circuit 7 that has received the current from the standby power supply 3 can automatically turn off the LED lamp 9 and notify the slave station 6 of the start of the parameter change process. Can be.

また、第１の実施形態では、予備電源３の出力する電流値をトリガーとしてＬＥＤ灯器９が消灯されるので、ＬＥＤ灯器９のＬＥＤ内の電子回路によるノイズ発生も無くなる。その結果、電力線パラメータの変更に際して、ＬＥＤ灯器９側のノイズを排除することが可能である。   Further, in the first embodiment, the LED lamp 9 is turned off by using the current value output from the standby power supply 3 as a trigger, so that noise generation by the electronic circuit in the LED of the LED lamp 9 is also eliminated. As a result, when changing the power line parameters, it is possible to eliminate noise on the LED lamp 9 side.

灯火監視制御システム１０では、ＬＥＤ灯器９を消灯した後、親局５と子局６にて電力線パラメータを変更するための電力線搬送通信を開始する（ＳＴ０７）。   In the lamp monitoring and control system 10, after turning off the LED lamp 9, the master station 5 and the slave station 6 start power line carrier communication for changing power line parameters (ST07).

以上述べたように、第１の実施形態では、ＬＥＤ灯器９の監視制御を電力線搬送通信にて行う監視制御装置１と、電流調整を行うＣＣＲ２と、電流調整を行わない予備電源３と、ＣＣＲ２から予備電源３に切り替える出力装置４とを備えている。そのため、第１の実施形態においては、ノイズなどにより電力線搬送通信が正常に行われなくなり電力線パラメータの調整が必要となった場合に、出力装置４がＣＣＲ２から予備電源３に切り替えることで、ノイズ発生の無い予備電源３を電源として、電力線パラメータの調整を行うことができる。   As described above, in the first embodiment, the monitoring control device 1 that performs the monitoring control of the LED lamp 9 by the power line carrier communication, the CCR 2 that performs the current adjustment, the standby power supply 3 that does not perform the current adjustment, And an output device 4 for switching from the CCR 2 to the standby power supply 3. Therefore, in the first embodiment, when power line carrier communication is not normally performed due to noise or the like and power line parameters need to be adjusted, the output device 4 switches from the CCR 2 to the standby power source 3 to generate noise. The power line parameters can be adjusted using the standby power supply 3 having no power supply as a power supply.

さらに、子局６の短絡回路７がＬＥＤ灯器９を消灯することにより、ＬＥＤ灯器９側のノイズも排除することができる。従って、第１の実施形態では、ＣＣＲ２側及びＬＥＤ灯器９側のノイズを共に排除することができる。これにより、灯火監視制御システム１０では親局５から子局６へ電力線搬送通信を正常に行うことができ、電力線搬送通信による電力線パラメータの変更を安定して行うことができる。   Furthermore, the short circuit 7 of the slave station 6 turns off the LED lamp 9, so that noise on the LED lamp 9 side can also be eliminated. Therefore, in the first embodiment, it is possible to eliminate both noise on the CCR 2 side and the LED lamp 9 side. Thereby, in the lamp monitoring and control system 10, power line carrier communication can be normally performed from the master station 5 to the slave station 6, and power line parameters can be stably changed by the power line carrier communication.

また、第１の実施形態では、予備電源３の出力するパラメータ設定用の電流がトリガーとなることで、子局６に対してパラメータ変更処理の開始を伝えている。そのため、電力線搬送通信が正常に行うことができない状況下で、子局６はパラメータ変更の開始を把握することができる。従って、子局６はＬＥＤ灯器９の消灯を異常と捉える心配がなく、その後のパラメータ変更処理をスムーズに実施することが可能である。   In the first embodiment, a parameter setting current output from the standby power supply 3 is used as a trigger to notify the slave station 6 of the start of parameter change processing. Therefore, the slave station 6 can recognize the start of the parameter change in a situation where the power line carrier communication cannot be performed normally. Therefore, the slave station 6 does not have to worry about turning off the LED lamp 9 as abnormal, and can smoothly perform the subsequent parameter change processing.

（他の実施形態）
以上説明した実施形態は、本発明の実施形態の一例として提示したものであり、発明の範囲を限定することは意図していない。本発明の実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形例は、発明の範囲や要旨に含まれると同様に、特許請求の範囲に記載された発明とその均等な範囲に含まれる。 (Other embodiments)
The embodiment described above is presented as an example of the embodiment of the present invention, and is not intended to limit the scope of the invention. The embodiment of the present invention can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents.

例えば、予備電源３が出力する電流は、ノイズのない高品質な電流であればよく、電流値は適宜選択可能である。また、出力装置４が電源をＣＣＲ２から予備電源３に切り替えるタイミング、つまり予備電源３を主回路に接続するタイミングは、電力線パラメータの設定時だけに限定されるものではない。例えば、ＬＥＤ灯器９の制御に関係の無い信号を電力線搬送通信によって送る場合であれば、出力装置４が動作してＣＣＲ２から予備電源３への切り替えを行い、電源として予備電源３を用いるようにしてもよい。このような実施形態によれば、予備電源３の使用頻度を高めることができ、構成要素を効率良く利用することが可能である。   For example, the current output from the standby power supply 3 may be a high-quality current without noise, and the current value can be appropriately selected. Further, the timing at which the output device 4 switches the power supply from the CCR 2 to the backup power supply 3, that is, the timing at which the backup power supply 3 is connected to the main circuit, is not limited only to the setting of the power line parameters. For example, if a signal irrelevant to the control of the LED lighting device 9 is transmitted by power line carrier communication, the output device 4 operates to switch from the CCR 2 to the standby power source 3 and use the standby power source 3 as the power source. It may be. According to such an embodiment, the use frequency of the backup power supply 3 can be increased, and the components can be used efficiently.

短絡回路７が短絡するトリガーとしては、予備電源３から出力されるパラメータ設定用の電流値を検知すること以外でもよく、例えば、短絡回路７への電流のＯＮ、ＯＦＦを一定時間継続して検知することや、短絡回路７に流れる電流値が予め設定された判定値を下回ることを、短絡回路７のトリガーとしてもよい。   The trigger for short-circuiting the short-circuit 7 may be other than detecting the current value for parameter setting output from the standby power supply 3. For example, ON / OFF of the current to the short-circuit 7 may be continuously detected for a certain period of time. Or that the current flowing through the short circuit 7 falls below a predetermined determination value may be used as a trigger of the short circuit 7.

また、監視制御装置１とは別に、予備電源３からの電源により電力線パラメータの設定を行うパラメータ設定部を独立して設けるようにしてもよい。この実施形態によれば、パラメータ設定部を設けることで、電力線パラメータの設定をより効率良く行うことができる。   Further, separately from the monitoring and control device 1, a parameter setting unit for setting power line parameters by a power supply from the standby power supply 3 may be provided independently. According to this embodiment, by providing the parameter setting unit, the setting of the power line parameters can be performed more efficiently.

さらに、図３に示すように、ノイズの発生により電力線搬送通信が正常に行えないことを判定する判定部１１を独立して設け、出力装置４は、判定部１１の判定結果に基づいて、ＣＣＲ２から予備電源３に切り替えるようにしてもよい。この実施形態によれば、判定部１１が電力線搬送通信が正常に行えないことを判定すると、出力装置４は、ＣＣＲ２から予備電源３に切り替える。そのため、電力線搬送通信が正常に行えなくなった時点で自動的に電力線パラメータを設定し直すことが可能である。これにより、電力線搬送通信の復旧を迅速に行うことができ、灯火監視制御システム１０の信頼性がより向上する。   Further, as shown in FIG. 3, a determination unit 11 for determining that power line carrier communication cannot be normally performed due to the occurrence of noise is provided independently, and the output device 4 outputs the CCR2 based on the determination result of the determination unit 11. May be switched to the standby power supply 3 from the power supply. According to this embodiment, when the determination unit 11 determines that the power line carrier communication cannot be performed normally, the output device 4 switches from the CCR 2 to the standby power supply 3. Therefore, it is possible to automatically reset the power line parameters when the power line carrier communication cannot be performed normally. Thereby, the restoration of the power line carrier communication can be quickly performed, and the reliability of the light monitoring and control system 10 is further improved.
