Description

【0001】
【発明の属する技術分野】
本発明は、リチウム電池等を主電源あるいはサブ電源として用いるガス安全装置に関するものである。
【0002】
【従来の技術】
ガス安全装置としてマイコンメータ等がある。マイコンメータは、ガスの供給量を計測しガス料金を徴収するためガス供給業者が需要家のところに設置するガスメータにマイコンが組み込まれたものを指す。
【0003】
この主たる機能はガス量の計測以外にガスの爆発等を防止するため、マイコンにあらかじめガス流量の使用されるパターンを記憶させておき、そのパターンからはずれたガス流量を検出すると遮断する機能を有する。
【0004】
また、近年では、ガスの元栓として居室内で室外に設けられたマイコンメータのガス弁を開閉できるものや、ガスの使用量の検針を自動的に行うために、外部と通信できる機能も持ち合わせているものもある。
【0005】
上記の制御回路は、マイコンメータの本体内に設置され、安全性を確保するために、一般の家庭の人が容易に取り出すことができないように、特殊なネジを用いられている。
【0006】
また、これらの電源は一般的に7年間から10年間交換せずに使用出来るよう高性能のリチウム電池が用いられる。
【0007】
マイコンメータのこれらの電池を廃棄するときには、未消費電力の残量を残した状態であるので電池を放電させるための処理が必要となる。
【0008】
一般的に制御回路が作動しなくなる電圧は初期電圧の60%〜70%を残した電圧である。もし不用意に廃棄されたリチウム電池が誤ってショートさせると、場合によっては爆発等の可能性があるばかりでなく、塩化チオニル系のリチウム電池は非常に強い腐食性の有毒ガスを発生させる。
【0009】
そのような危険性を避けるために、電池を完全に放電させてから廃棄する必要がある。
【0010】
【発明が解決しようとする課題】
しかしながら、これらの廃棄処理は専門業者でないとその処理が特殊な為一般にはできず、1)処理に手間がかかり、人件費が増大する。2)電池放電の処理が困難なため、電池の放電処理が十分に行われないまますなわち、電池の容量が残ったまま、廃棄される可能性があるという課題があった。
【0011】
【課題を解決するための手段】
本発明は、ガス通路を開放遮断するガス弁と、プリント基板上に構成され前記ガス弁を制御する制御回路と、この制御回路と前記ガス弁に電源を供給する電池と、この電池を強制的に放電させる電池放電部とを具備し、前記電池放電部は電池に直列接続した抵抗と導電性金属の端子とからなるとともに、同端子は、ガス安全装置本体の外部から導電性金属の短絡片で短絡できるように前記ガス安全装置本体の外郭の一部に固定したものである。
【0012】
【発明の実施の形態】
本発明のガス安全装置は、ガス通路を開放遮断するガス弁と、プリント基板上に構成され前記ガス弁を制御する制御回路と、この制御回路と前記ガス弁に電源を供給する電池と、この電池を強制的に放電させる電池放電部とを具備し、前記電池放電部は電池に直列接続した抵抗と導電性金属の端子とからなるとともに、同端子は、ガス安全装置本体の外部から導電性金属の短絡片で短絡できるように前記ガス安全装置本体の外郭の一部に固定したものである。
【0013】
したがって、端子間を導電性金属の短絡片で短絡させることにより、簡単に放電作業を行うことができるものである。
【0014】
【参考実施例】
以下本発明の実施例を述べる前に参考実施例について説明する。
【0015】
(参考実施例1)
図1,2において、1はマイコンメータ、2はガス弁、3は制御回路、4はマイクロコンピュータ(以下マイコンと言う)、5はリチウム電池、6は電池放電部、7はその電池放電部6を構成する抵抗、8は同半田付けランドを示す。
【0016】
ガスはガス弁2を通りガス量計測部2aを経てガス器具に供給される。
【0017】
制御回路3は、ガス量計測部2aからの信号によりガスの使用パターンを監視し、異常な使用パターンが生じたときには、ガス弁2を制御し、ガスの供給停止を行うように動作する。
【0018】
また、制御回路3にはマイコン4以外の回路も含まれるがこの電源はリチウム電池5によりまかなわれる。
【0019】
さらに、電池放電部6は抵抗7を介して半田付けランド8の相対向する一対電極間を半田付けする事によりショートする形で構成される。
【0020】
上記構成において、マイコンメータ1の寿命が来て回収したマイコンメータの廃棄処理を行うとき、半田付けランド8を半田付けして短絡する。これにより、リチウム電池5、抵抗7の閉ループ回路ができ、前記リチウム電池5を強制放電させることができる。
【0021】
【実施例】
(実施例1)
前記参考実施例をふまえ次に本発明の実施例を図3を参照して説明する。
【0022】
なお、図1,2と同一符号を付した構成は同一の機能を有するもので、具体的説明は参考実施例1のものを便宜上援用する。
【0023】
電池放電部6には前記参考実施例1の半田付けランドの代わりに導電性金属よりなる端 子14が接続されている。
【0024】
そして、この端子14はマイコンメータ外郭12に固定され、通常はフタ13で外部と隔離されている。
【0025】
上記の構成において、電池の破棄処理を行うときには、フタ13を取り除いて、外部から導電性金属の短絡片であるショートピン15を端子14に接続して短絡する。
【0026】
これにより、リチウム電池5、抵抗7の閉ループ回路ができ、前記リチウム電池5を強制放電させることができる。
【0027】
この実施例1の構成によれば、メータの外部から電池放電部6を制御してリチウム電池5を放電させることができるので、
(1)電池を放電させるために、回収したメータの裏蓋をあけて回路基盤を取り出す必要がなくなるので、人件費を削減することができる
(2)回路基盤内の電池を放電させるための装置を必要としない
(3)電池放電の処理に手間を省くことができるため、電池の容量が残ったまま、廃棄される危険性が小さくなる
などの効果を奏するものとなる。
【0028】
なお、実施例1として、ガス遮断装置を用いて説明したが、本発明は、これに限らず、回路部が電子式水道メータ装置、電力メータ装置、自動通報装置であっても同様の構成が考えられる。電池の種類はリチウム電池に限らない。

BACKGROUND OF THE INVENTION
The present invention relates to a gas safety device using a lithium battery or the like as a main power source or a sub power source.
[0002]
[Prior art]
There is a microcomputer meter etc. as a gas safety device. A microcomputer meter refers to a gas meter that is installed in a gas meter installed by a gas supplier at a consumer in order to measure gas supply and collect gas charges.
[0003]
In order to prevent gas explosion, etc., in addition to measuring the amount of gas, this main function has a function of storing a pattern in which the gas flow rate is used in advance in the microcomputer and shutting off if a gas flow rate deviating from the pattern is detected. .
[0004]
Also, in recent years, it has a function that can communicate with the outside to automatically open and close the gas valve of a microcomputer meter installed in the room as a gas main stopper and to automatically measure the amount of gas used. Some are.
[0005]
The control circuit is installed in the main body of the microcomputer meter, and a special screw is used so that a general household person cannot easily take it out in order to ensure safety.
[0006]
These power supplies are generally high-performance lithium batteries so that they can be used without replacement for 7 to 10 years.
[0007]
When discarding these batteries of the microcomputer meter, a process for discharging the batteries is required because the remaining amount of unconsumed power is left.
[0008]
Generally, the voltage at which the control circuit does not operate is a voltage that leaves 60% to 70% of the initial voltage. If an accidentally discarded lithium battery is accidentally short-circuited, it may not only explode, but thionyl chloride-based lithium batteries generate a very strong corrosive toxic gas.
[0009]
In order to avoid such a risk, it is necessary to completely discharge the battery and then discard it.
[0010]
[Problems to be solved by the invention]
However, these disposal processes cannot be generally performed unless they are specialists because the process is special. 1) The process is troublesome and labor costs increase. 2) Since the battery discharge process is difficult, there is a problem that the battery may be discarded while the battery discharge process is not sufficiently performed, that is, the battery capacity remains.
[0011]
[Means for Solving the Problems]
The present invention includes a gas valve that opens and closes a gas passage, a control circuit that is configured on a printed circuit board and controls the gas valve, a battery that supplies power to the control circuit and the gas valve, and the battery is forced A battery discharge section for discharging the battery, and the battery discharge section includes a resistor and a conductive metal terminal connected in series to the battery, and the terminal is a short-circuit piece of the conductive metal from the outside of the gas safety device main body. It is fixed to a part of the outline of the gas safety device main body so that it can be short-circuited.
[0012]
DETAILED DESCRIPTION OF THE INVENTION

[0016]
The gas passes through the gas valve 2 and is supplied to the gas appliance through the gas amount measuring unit 2a.
[0017]
The control circuit 3 monitors the gas usage pattern based on a signal from the gas amount measuring unit 2a, and operates to control the gas valve 2 and stop the gas supply when an abnormal usage pattern occurs.
