本考案は、ガス漏れ警報器がガス漏れを検出し
たときには、まず住戸内に警報を発し、それでも
ガス漏れが続いているようなときには初めて中央
監視室等の受信機盤によるガス漏れ警報の出力を
行なうようにしたガス漏れ警報器の集中監視装置
に関する。[Detailed explanation of the invention] In this invention, when a gas leak alarm detects a gas leak, it first issues an alarm within the dwelling unit, and if the gas leak continues, it first sends an alarm to the receiver panel in the central monitoring room, etc. The present invention relates to a centralized monitoring device for a gas leak alarm that outputs a gas leak alarm based on the following information.
近年、共同住宅等におけるガス漏れ事故による
被害の大きさに鑑み、ガス漏れ警報器の設置を義
務付けし、ガス漏れ事故を未然に防ごうとする法
制化の動きが見られる。 In recent years, in view of the scale of damage caused by gas leak accidents in apartment buildings, etc., there has been a movement to legislate the installation of gas leak alarms in an effort to prevent gas leak accidents.
そのため、各住戸毎にガス漏れ警報器を設置
し、ガス漏れを検知したときにはブザー等で警報
を発して早目に適切な処置を構ずるようにするこ
とが考えられているが、各住戸毎に独立して行な
うガス漏れの監視では、自殺行為によるガス漏れ
の場合に、警報器の電源が抜かれてしまうこと
で、ガス漏れ監視の機能が果せず、従つて、管理
人室等に設けた受信機盤による各住戸のガス漏れ
警報器集中的に監視する装置が考えられている。 Therefore, it is considered that gas leak alarms should be installed in each residential unit, and when a gas leak is detected, a buzzer will sound the alarm so that appropriate measures can be taken as soon as possible. However, in the case of a gas leak caused by an act of suicide, the gas leak monitoring function cannot be achieved because the power to the alarm is disconnected in the event of a gas leak caused by an act of suicide. A device that centrally monitors gas leak alarms in each dwelling unit using a receiver panel is being considered.
ところで、現在実用化されているガス漏れ警報
器は、ガス器具を点火もしくは止めるときの漏れ
ガス等による誤報を防止するため、ガス漏れ検出
が所定時間、例えば20秒間継続して行なわれたと
きに、警報器を鳴らして警報を発するような蓄積
機能をもたせている。 By the way, in order to prevent false alarms caused by gas leaks when turning on or off gas appliances, gas leak alarms currently in practical use detect gas leaks for a predetermined period of time, for example, 20 seconds. , it has a storage function that sounds an alarm and issues an alarm.
従つて、このように蓄積警報機能をもつたガス
漏れ警報器を集中監視するときには、誤報を防止
するため、ガス漏れ警報器の蓄積回路の出力を受
信機に伝送するか、あるいは受信機側に同じ蓄積
回路を設け、ガス漏れ警報器の検出出力をそのま
ま伝送することが考えられる。 Therefore, when centrally monitoring a gas leak alarm device with an accumulation alarm function, in order to prevent false alarms, it is necessary to transmit the output of the accumulation circuit of the gas leak alarm device to the receiver, or to transmit it to the receiver side. It is conceivable to provide the same storage circuit and transmit the detection output of the gas leak alarm as is.
このような集中監視方式では、各住戸でのガス
漏れ警報の出力と同時に、中央の受信機盤でもガ
ス漏れ警報の出力が行なわれ、受信機盤でガス漏
れ警報があつたときには、直ちにガス会社消防署
等に緊急連絡を行なつて迅速な処理を構ずるよう
になる。 In this type of centralized monitoring system, gas leak alarms are output from the central receiver panel at the same time as gas leak alarms are output from each dwelling unit, and when a gas leak alarm is issued from the receiver panel, the gas company is immediately notified. People begin to make emergency calls to the fire department, etc., and take immediate action.
ところが、住戸内でのガス漏れ警報により居住
者が適切な措置を構じて、ガス漏れを止めたよう
なときにも、中央側では、すでにガス会社等への
緊急連絡をしてしまつており、ガス漏れを止める
ことができたにもかかわらず大さわぎになつてし
まう恐れがあり、ガス漏れを起した住戸のプライ
バシーを著しく損なうこととなり、しいてはガス
漏れ警報設備そのものの設置について住人の反感
を招きかねないという問題がある。 However, even when residents take appropriate measures to stop the gas leak in response to a warning of a gas leak inside their unit, the central office has already made an emergency contact with the gas company, etc. However, even if the gas leak has been stopped, there is a risk that it will cause a big commotion, seriously impairing the privacy of the unit where the gas leak occurred, and causing residents to have difficulty installing the gas leak alarm system themselves. The problem is that it could lead to backlash.
本考案は上記に鑑みてなされたもので、ガス漏

信機盤でガス漏れ警報を行なうようにしたもので
ある。 The present invention was developed in view of the above, and its purpose is to perform appropriate centralized monitoring of gas leaks without taking excessive measures for the living area of each dwelling unit when performing intensive gas leak monitoring. Therefore, when a gas leak is detected, an alarm is first issued within the dwelling unit to have the resident take action, and only when the gas leak continues is a gas leak alarm issued from the central receiver panel. This is what I did.
以下、図面に基づいて本考案を説明する。 Hereinafter, the present invention will be explained based on the drawings.

As shown in the figure, a gas leak detection section 5, a first storage circuit 6 that outputs a gas leak detection signal when the gas leak detection signal continues for a predetermined time T1 , for example 20 seconds, and a storage circuit 6.
It consists of an alarm device 7 using a buzzer or the like that sounds with the output of the gas leak to notify the residence of a gas leak, and a commercial AC source of 100 V is used as the power source, and the output of the gas leak detector 5 is the normal one. Three types of signal output are generated: 6 volts when a gas leak is detected, 12 volts when a gas leak is detected, and zero volts when the power is disconnected due to suicide or other reasons.

であるという効果が得られる。 As explained above, according to the present invention, when a gas leak is detected, an alarm is issued in the dwelling unit after the accumulation time set to prevent false alarms has elapsed, and the resident first makes a self-judgment to detect the gas leak. When a gas leak is still detected after sufficient time has passed for the resident to take action, the gas leak alarm is sent to the central monitoring side for the first time. For gas leaks that can be treated, there is no need to take excessive measures by mobilizing the gas company, fire department, etc. This eliminates the risk of unnecessarily invading the privacy of each residence, and also prevents gas leaks that cannot be dealt with by each residence. Since gas leak alarms are issued centrally, appropriate measures can be taken.In this way, the status of gas leak alarms in each dwelling unit can be appropriately and centrally monitored, increasing residents' confidence in the device. At the same time, it is possible to obtain an effect that is extremely useful for preventing gas leak accidents.
