【０００１】
【発明の属する技術分野】
本発明は、被検知ガスの検出及びその被検知ガスの濃度に基づく警報動作を電池駆動により行うガス警報器に関する。
【０００２】
【従来の技術】
近年、ガス検知素子の開発とともに、その小電力駆動化がすすみ、電池駆動されるガス検知器が用いられるようになってきている。また、この種のガス検知器のうち、電池がきれると重大な障害の発生が予想されるような用途に用いられるものには、電池残存容量（残量）の表示を行うことが考えられている。この際、前記電池残量は、電池交換時に想定される電池使用可能時間から、実際に前記ガス検知器の使用された通電使用時間を減算処理する事によって電池残量とし、その電池残量を表示することが考えられている。
しかし、この種のガス検知器のうち、警報動作を可能とするガス警報器の場合、通常のガス検出動作時と、警報動作時とで著しく使用電力量が異なり、電池残量は、単に通電使用時間で判断することは出来ない。
【０００３】
【発明が解決しようとする課題】
つまり、上述の従来の技術によれば、ガス警報器の電池の交換時期を正確に判断することが出来ないために、機器の使用中に電池切れになる問題を回避するためには、電池が切れるまでに十分余裕がある時期にその電池の交換をせざるを得ず、そのために、電池を有効利用できないという問題点があり、環境問題その他の側面から改善が望まれている。
【０００４】
従って、本発明の目的は、上記欠点に鑑み、電池残量が正確に把握でき、有効利用することのできるガス警報器を提供することにある。
【０００５】
【課題を解決するための手段】
この目的を達成するための本発明の被検知ガスの検出及びその被検知ガスの濃度に基づく警報動作を電池駆動により行うガス警報器の特徴構成は、
前記警報動作を行う警報部と、
一定時間を計測するタイマ部と、
電池残量を記憶する記憶部と、
前記警報部の動作状態に基づいて電池使用量を求めて、前記記憶部に記憶された前記電池残量と前記電池使用量とから最新の電池残量を求める演算部と、
前記演算部によって求められた前記最新の電池残量を表示する電池残量表示部と、を設け、
前記一定時間毎に前記警報部の動作状態をチェックし、
前記警報部が前記警報動作を行っているときは、警報フラグをセットすると共に前記一定時間を警報持続時間として積算し、
前記警報部が前記警報動作を行っておらず、かつ、前記警報フラグがセットされているときは、前記一定時間を前記警報持続時間に積算した上で、前記記憶部に記憶された電池残量と、前記警報動作の時間あたりの電池使用量及び積算された前記警報持続時間と、から前記最新の電池残量を求めて前記記憶部に記憶させると共に、その後、前記警報フラグのリセット及び前記警報持続時間のクリアを行い、
前記警報部が前記警報動作を行っておらず、かつ、前記警報フラグがセットされていないときは、前記記憶部に記憶された電池残量と、前記検出動作の時間あたりの電池使用量及び前記一定時間と、から前記最新の電池残量を求めて前記記憶部に記憶させる点にある。
【０００６】
〔作用効果〕
一定時間ごとに警報部の動作状態をチェックするため、前記被検知ガスの検出動作時間あたりの電池使用量（Ａ）と一定時間(ｋ）と、または、前記警報動作時間あたりの電池使用量（Ｂ）と警報持続時間（ｔｂ）と、に基づき、最新の電池残量がリアルタイムに電池残量表示部に表示される。電池の使用量は、時間あたりの使用量と使用時間の積として求めることが出来るから、たとえば、
Ｒ２＝Ｒ１−Ａ・ｋ
または、
Ｒ２＝Ｒ１−Ｂ・ｔｂ
を求めることにより、Ｒ２を現在の電池残量として求めることが出来る。
尚、前記記憶部が初期の電池残量を記憶するものであれば、前記検出動作時間及び警報動作時間は、電池交換時からの総動作時間として与えればよく、前記記憶部が現在の電池残量を記憶するものであれば、前記検出動作時間及び警報動作時間は、その現在の電池残量を記憶部に記憶させる更新時間であればよく、検出動作時と警報動作時とで、更新動作を異ならせる場合、それぞれ別個に設定するなど、種々の形態を採用することが出来る。
このようにして求められた現在の電池残量は電池残量表示部によりガス警報器に表示することが出来使用者にその電池の交換時期を報知することが可能となる。
従って、単に電池残量を従来の技術のようにガス警報器の使用時間で判断するのではなく、使用電力量によって求めることが出来るようになるから、このようにして求められた電池残量はより正確なものとなり、使用者は電池の交換時期を正確に判断することが出来るようになる。そのため、機器の使用中に電池切れになる問題を回避するために、電池が切れるまでに十分余裕がある時期にその電池の交換をせざるを得ず、電池を有効利用できないというような上述の問題を派生しにくくなった。
【０００７】
【発明の実施の形態】
以下に本発明の実施の形態を図面に基づいて説明する。
図１に示すように、本発明のガス警報装置は、ガス検知素子をガス検知回路に組み込んでなるセンサ部１と、前記センサ部１からの出力信号を受けて検知対象ガス中の被検知ガスの濃度を知る検出動作部２とを備え、前記検出動作部２により検出された出力信号が、前記検知対象ガス中の被検知ガス濃度が警報を必要とする警報濃度に達していると判断される場合に警報音等を発生させ、周囲に被検知ガスが警報濃度以上に存在していることを報知する警報部３を備える。
【０００８】
また、前記検出動作部２と、前記警報部３には、その動作時間を計測するタイマ部４を設けてあり、電池残量を記憶する記憶部５からの電池残量情報と、前記タイマ部４からの動作時間情報とに基づき、現在の電池残量を求める演算部６を設けてある。さらに、電池残量表示部７が設けてあり、前記演算部６による演算結果がリアルタイムで表示される構成としてある。
【０００９】
以下、本発明のガス警報装置における前記演算部６の電池残量算出手順の一例をフロー図に従って説明する。
【００１０】
【実施例】
図２に示すように、演算部は所定時間（ｋ）ごとに現在の電池残量を求める。
＃１ まず現在の電池残量を表示するとともに、時間（ｋ）ごとに警報部３の動作状態をチェックする。
＃２ 警報部が動作している場合は、警報部３が動作したことを示す警報フラグをセットするとともに、警報音の持続時間を積算する。
＃３ 警報部の作動していない場合、警報フラグの有無をチェックする。
警報フラグがなければ、表示中の電池残量から、（前記被検知ガスの検出動作時間あたりの電池使用量（Ａ））×ｋを減算処理して新たに現在の電池残量として＃１に戻る。（検出動作による電池残量の減算）
警報フラグがある場合、（前記警報動作時間あたりの電池使用量（Ｂ））×（＃２で積算された警報音の持続時間）を表示中の電池残量から減算処理する。この後、前記警報音の持続時間をクリアするとともに警報フラグをリセットし、新たに現在の電池残量として＃１に戻る。（警報動作による電池残量の減算）
これにより、前記記憶部には、現在の電池残量が更新されることになり、使用電気量が電池残量に正確に反映させられ、電池の交換時期を的確に判断できるようになった。

BACKGROUND OF THE INVENTION
The present invention relates to a gas alarm device that performs detection of a gas to be detected and an alarm operation based on the concentration of the gas to be detected by battery driving.
[0002]
[Prior art]
In recent years, with the development of gas detection elements, the use of low-power driving has progressed, and battery-driven gas detectors have come to be used. Of these types of gas detectors, it is conceivable to display the remaining battery capacity (remaining capacity) for applications in which a serious failure is expected when the battery runs out. Yes. At this time, the remaining battery level is determined as the remaining battery level by subtracting the energized usage time actually used by the gas detector from the expected battery available time when replacing the battery. It is considered to be displayed.
However, among these types of gas detectors, in the case of a gas alarm that enables an alarm operation, the amount of power used differs significantly between the normal gas detection operation and the alarm operation, and the remaining battery capacity is simply energized. It cannot be judged by usage time.
[0003]
[Problems to be solved by the invention]
In other words, according to the above-described conventional technology, since it is not possible to accurately determine the replacement time of the battery of the gas alarm device, in order to avoid the problem that the battery runs out during use of the device, There is a problem that the battery must be replaced at a time when there is a sufficient margin before it runs out, and therefore, there is a problem that the battery cannot be used effectively, and improvements are desired from environmental and other aspects.
[0004]
Accordingly, an object of the present invention is to provide a gas alarm device that can accurately grasp the battery remaining amount and can be used effectively in view of the above drawbacks.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the characteristic configuration of the gas alarm device for detecting the detected gas of the present invention and performing the alarm operation based on the concentration of the detected gas by battery driving is
An alarm unit for performing the alarm operation;
A timer unit for measuring a certain time ;
A storage unit for storing the remaining battery capacity ;
An operation unit for obtaining a battery usage amount based on an operating state of the alarm unit and obtaining a latest battery remaining amount from the battery remaining amount and the battery usage amount stored in the storage unit ;
A battery level display unit for displaying the latest battery level determined by the calculation unit,
Check the operating state of the alarm unit at regular intervals,
When the alarm unit is performing the alarm operation, the alarm flag is set and the fixed time is integrated as an alarm duration,
When the alarm unit is not performing the alarm operation and the alarm flag is set, the battery remaining amount stored in the storage unit is added to the alarm duration after the certain time is integrated. And the battery usage amount per time of the alarm operation and the integrated alarm duration, the latest battery remaining amount is obtained and stored in the storage unit, and then the alarm flag is reset and the alarm Clear the duration,
When the alarm unit is not performing the alarm operation and the alarm flag is not set, the remaining battery level stored in the storage unit, the battery usage per time of the detection operation, and the The latest battery remaining amount is obtained from a certain time and stored in the storage unit .
[0006]
[Function and effect]
To check the operation status of the alarm unit at regular time intervals, the battery using doses per detection operation time of the gas to be detected (A) and a predetermined time (k), or, the battery using the dose per said alarm operation time ( B) an alarm duration and (tb), on the basis of, the latest battery remaining amount is displayed on the battery remaining display unit in real time. The amount of the batteries, since it can be determined as the product of used dosage and usage time per time, for example,
R2 = R1-A · k
Or
R2 = R1-B · tb
R2 can be obtained as the current remaining battery level.
If the storage unit stores the initial battery remaining amount, the detection operation time and alarm operation time may be given as the total operation time from the battery replacement, and the storage unit may store the current battery remaining amount. If the amount is stored, the detection operation time and the alarm operation time may be an update time for storing the current battery remaining amount in the storage unit, and the update operation is performed during the detection operation and the alarm operation. When different from each other, various forms such as setting them separately can be adopted.
The current remaining battery level obtained in this way can be displayed on the gas alarm by the remaining battery level display unit, and the user can be notified of the replacement time of the battery.
Therefore, since the remaining battery level can be determined not by the usage time of the gas alarm as in the prior art but by the amount of power used, the remaining battery level determined in this way is It becomes more accurate, and the user can accurately determine the battery replacement time. Therefore, in order to avoid the problem that the battery runs out during use of the device, the battery must be replaced at a time when there is sufficient time until the battery runs out, and the battery cannot be used effectively. It became difficult to derive the problem.
