(Reference Embodiment 4)
Next, reference embodiment 4 will be described with reference to FIGS. Parts having the same structure and the same function as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts are mainly described.
図１４に示すように、地中に埋設された感震器４２と、前記感震器４２の地震発生を判定する地震判定手段４３と、前記地震判定手段４３からの地震発生信号を送信する送信手段４４と備えた地震計４５と、前記送信手段４４からの地震発生信号を受信する受信手段
４６と前記受信手段４６からの地震発生信号により電力供給を遮断する電力遮断スイッチ１４を制御する制御手段１５とを備えた電気ブレーカー４７とで構成した。ここで、地震計４５の地震判定手段４３で行う処理のフローチャートを図１５に、電気ブレーカー４７の制御手段１５で行う処理のフローチャートを図１６に示す。
As shown in FIG. 14, the seismic device 42 buried in the ground, the earthquake determination means 43 for determining the occurrence of the earthquake in the seismic device 42, and the transmission for transmitting the earthquake occurrence signal from the earthquake determination means 43 Means 44, seismometer 45, receiving means 46 for receiving an earthquake occurrence signal from transmitting means 44, and control means for controlling power cut-off switch 14 for shutting off power supply by the earthquake occurrence signal from receiving means 46 15 and an electric breaker 47 equipped with 15. Here, the flowchart of the process performed by the earthquake determination means 43 of the seismometer 45 is shown in FIG. 15, and the flowchart of the process performed by the control means 15 of the electric breaker 47 is shown in FIG.
このような構成において、地震判定手段４３は、感震器４２からの信号を受け地震振動かどうかを常時判定しており、地震が検知されれば、送信手段４４によって地震発生信号が送信される。また、地震が検知されない場合でも、所定の時間間隔、例えば１日に１回、震度０として信号を送信することとしている。 In such a configuration, the earthquake determination means 43 always receives the signal from the seismic device 42 and determines whether it is an earthquake vibration. If an earthquake is detected, an earthquake occurrence signal is transmitted by the transmission means 44. . Even when no earthquake is detected, a signal is transmitted with a seismic intensity of 0 at a predetermined time interval, for example, once a day.
そして、電気ブレーカー４７の受信手段４６は、地震計４５の送信手段４４からの信号を受信し、受信情報を制御手段１５が判定する。そして、正常か、地震異常か、通信異常かを表示装置１９に表示する。通信異常は長期間、例えば７日以上、受信信号がない場合に判定することとした。そして、地震情報信号から震度５以上の場合、異常信号と判定し電力遮断スイッチを遮断するものである。 And the receiving means 46 of the electric breaker 47 receives the signal from the transmitting means 44 of the seismometer 45, and the control means 15 determines reception information. Then, it is displayed on the display device 19 whether it is normal, an earthquake abnormality, or a communication abnormality. The communication abnormality is determined when there is no reception signal for a long period, for example, 7 days or longer. And when the seismic intensity is 5 or more from the earthquake information signal, it is determined as an abnormal signal and the power cut-off switch is cut off.
地震計からは、地震に関する詳しい情報が送信されてくるため、震度、または発生状況に応じて、電気ブレーカーの遮断を決定することができる。例えば、震度３程度の地震でも発生頻度が非常に高い場合には、大電力を消費して火災などの原因になりやすい器具が接続されている電気ブレーカーは、安全を確保するために事前に遮断しておくような制御を行うことができる。 Since the seismometer transmits detailed information about the earthquake, it is possible to determine the interruption of the electric breaker according to the seismic intensity or the occurrence situation. For example, if the frequency of occurrence is very high even in an earthquake with a seismic intensity of about 3, an electrical breaker that is connected to a device that easily consumes a large amount of power and may cause a fire or the like is shut off in advance to ensure safety. Such control can be performed.
また、気象庁が設置している地震計を用いれば、無線通信によって設置されている地域の全電気ブレーカーに地震情報を発信することができ、地域全体で防災に対応できる電力供給システムとすることができる。 In addition, if a seismometer installed by the Japan Meteorological Agency is used, earthquake information can be transmitted to all the electrical breakers in the area where wireless communication is installed, and a power supply system that can respond to disaster prevention throughout the area. it can.
前記参考実施の形態の説明をふまえ以下本発明の実施の形態を説明する。 Based on the description of the reference embodiment, an embodiment of the present invention will be described below.
（実施の形態１）
図８から図１０は本発明の実施の形態１を示し、上記参考実施の形態１と同一構造で、かつ同一作用をする部分には同一符号を付して詳細な説明は同参考実施の形態１を援用し、異なる部分を中心に説明する。
(Embodiment 1)
8 to 10 show the first embodiment of the present invention. The same reference numerals are given to the parts having the same structure and the same function as those of the first embodiment, and the detailed description will be given in the first embodiment. 1 will be used, and different parts will be mainly described.
図８に示すように、温度センサー３１により火災を検知してブザー３２で報知する火災判定手段３３と、火災発生信号を送信する送信手段３４とを備えた火災報知器３５と、電力の供給を遮断する電力遮断スイッチ１４と、前記火災報知器３５からの火災発生信号を受信する受信手段１３と、前記受信手段１３からの前記火災発生信号により、特定の電力遮断スイッチ１４を遮断する制御手段１５を備えた電気ブレーカー１６とで構成した。ここで、火災報知器３５の異常判定手段３３で行う処理のフローチャートを図９に、電気ブレーカー１６の制御手段１５で行う処理のフローチャートを図１０に示す。 As shown in FIG. 8, a fire alarm 35 having a fire determination means 33 for detecting a fire with a temperature sensor 31 and notifying with a buzzer 32, a transmission means 34 for transmitting a fire occurrence signal, and a power supply. The power cutoff switch 14 to be shut off, the receiving means 13 for receiving a fire occurrence signal from the fire alarm 35, and the control means 15 for shutting off a specific power cutoff switch 14 by the fire occurrence signal from the receiving means 13 And an electric breaker 16 equipped with Here, the flowchart of the process performed by the abnormality determination means 33 of the fire alarm 35 is shown in FIG. 9, and the flowchart of the process performed by the control means 15 of the electric breaker 16 is shown in FIG.
このような構成において、火災報知器３５に設置された温度センサー３１からの信号を受け火災発生かどうかを常時判定しており、異常が検知されれば、送信手段によって火災発生信号が送信される。また、異常が検知されない場合でも、所定の時間間隔、例えば１日に１回、正常信号を送信することとしている。そして、電気ブレーカー１６の受信手段１３は、火災報知器３５の送信手段３４からの信号を受信し、受信情報を制御手段が判定する。そして、正常か、火災発生か、通信異常かを表示装置１９に表示する。通信異常は長期間、例えば７日以上、受信信号がない場合に判定することとした。そして、火災発生信号と判定したときは、特定の電力遮断スイッチ１４を遮断するものである。 In such a configuration, a signal from the temperature sensor 31 installed in the fire alarm 35 is received to determine whether or not a fire has occurred. If an abnormality is detected, a fire occurrence signal is transmitted by the transmission means. . Even if no abnormality is detected, a normal signal is transmitted at a predetermined time interval, for example, once a day. And the reception means 13 of the electric breaker 16 receives the signal from the transmission means 34 of the fire alarm 35, and a control means determines reception information. Then, the display device 19 displays whether it is normal, a fire has occurred, or a communication error has occurred. The communication abnormality is determined when there is no reception signal for a long period, for example, 7 days or longer. And when it determines with a fire occurrence signal, the specific electric power interruption switch 14 is interrupted | blocked.
よって、火災発生時に特定の機器への電力供給を遮断することができる。例えば、電気ストーブやガス器具の運転は中止させ、照明器具や非常通報器具への通電は継続するなど、必要に応じて通電制御を行うことができ、避難のための安全確保することができるのである。 Therefore, it is possible to cut off the power supply to a specific device when a fire occurs. For example, the operation of electric stoves and gas appliances can be stopped and the lighting appliances and emergency call appliances can be energized. is there.
また、火災発生信号は、火災報知器の送信手段に接続された電力線に搬送して送信する。この信号を同じ電力線に接続された電気ブレーカーの受信装置で受信して火災発生信号を受信する構成としたため、既設の電力線が利用でき、情報通信のための設置工事を簡略化することができる。 Moreover, a fire occurrence signal is conveyed and transmitted to the power line connected to the transmission means of a fire alarm. Since this signal is received by the receiving device of the electric breaker connected to the same power line and the fire occurrence signal is received, the existing power line can be used, and the installation work for information communication can be simplified.
また、火災報知器に感震器を組み合わせて、地震検知をより精度よく行えば、地震による電力遮断の精度はより向上することは十分に考えられる。 Moreover, if the seismoscope is combined with the fire alarm and the earthquake detection is performed with higher accuracy, it is sufficiently conceivable that the accuracy of power interruption due to the earthquake will be further improved.
以上説明したように本発明の電力遮断システムによれば、火災報知器からの異常情報を受信して電力遮断スイッチを遮断することで火災時に特定機器の電力を遮断することができる。 As described above, according to the power cut-off system of the present invention, it is possible to cut off the power of a specific device in the event of a fire by receiving abnormality information from a fire alarm and turning off the power cut-off switch.
以上のように本発明にかかる電力遮断システムによれば、火災を検知したときに電気ストーブのような火災拡大につながる器具を停止させることができ、災害を最小限に抑えることができるものであり、例えば、ガス供給系が電気的に制御されるものにあってはそのガス供給遮断にも利用できるものである。 As described above, according to the power cut-off system according to the present invention, when a fire is detected, an appliance such as an electric stove that leads to a fire expansion can be stopped, and a disaster can be minimized. For example, if the gas supply system is electrically controlled, it can also be used to shut off the gas supply.
