Description

本発明は、電池で駆動する警報器に関する。 The present invention relates to an alarm device driven by a battery.

従来、火災検出時や点検異常時(電池電圧低下時やセンサ異常時など)に警報音を鳴動させる警報鳴動回路と表示を行う表示灯を備え、火災発生時に電池切れで機能が発揮できないということがないように、定期的に電池電圧試験として電池の電圧を測定して、電池が所定の電池残量以下になると、電池あるいは警報器自体を交換すべきことを、警報音を鳴動させて警報する警報器が知られている(例えば、特許文献1参照)。
このような警報器は、警報音の鳴動と表示灯の点灯をさせていない監視時においては、電池を長持ちさせるために消費電流が抑えられているが、警報音を鳴動させる警報時においては、消防法の規格により70dB以上の音圧で火災警報を出力することが義務づけられており、警報音の鳴動と表示灯を点灯させるときには消費電流が大きくなる。
通常、電池は、放電を行い電池残量が減るにつれて電圧は徐々に降下していき、やがてある電圧(以下、この電圧を終止電圧と呼び、そのときの電池残量を終止残量と呼ぶ)を境にその低下の度合いが急激になる。つまり、電池が終止残量となったとき、電池からの出力電流が微少な場合には、電池は終止電圧を出力するが、電池からの出力電流が大きい場合には、終止電圧から急激に電圧が低下してしまうこととなる。
そのため、警報器においては、火災等発生時に警報を行うために警報音を鳴動させたときに急激に電池の電圧が低下してしまい警報が行えないということがないように、警報を行ったときと同じ電流を疑似電流として流して電圧を測定し、電池の監視を行っている。
Conventionally, an alarm sounding circuit that sounds an alarm sound when a fire is detected or inspection is abnormal (such as when the battery voltage is low or a sensor is abnormal) and an indicator lamp that displays the alarm are not available. The battery voltage is measured periodically as a battery voltage test, and when the battery falls below the specified battery level, an alarm is sounded to alert you that the battery or alarm device itself should be replaced. An alarm device is known (see, for example, Patent Document 1).
In such an alarm device, the current consumption is suppressed in order to make the battery last longer when monitoring the alarm sound and the indicator light is not turned on, but at the time of the alarm sounding the alarm sound, According to the standards of the Fire Service Act, it is obliged to output a fire alarm with a sound pressure of 70 dB or more, and the current consumption increases when the alarm sounds and the indicator lamp is turned on.
Normally, the battery discharges and the voltage gradually decreases as the remaining battery level decreases, and eventually the voltage (hereinafter, this voltage is called the end voltage, and the remaining battery level is called the end remaining level). The degree of decrease becomes sharper at the border. In other words, when the battery reaches the end of charge, if the output current from the battery is very small, the battery outputs the end voltage, but if the output current from the battery is large, the voltage suddenly increases from the end voltage. Will be reduced.
Therefore, in the alarm device, when the alarm is issued so that the alarm voltage is suddenly lowered and the alarm cannot be performed when the alarm sound is sounded in order to give an alarm in the event of a fire, etc. The battery is monitored by measuring the voltage by passing the same current as a pseudo-current.

しかしながら、新品の電池で警報器を動作させた当初は、警報音を鳴動させるために十分な電池容量があり警報音を鳴動させたときに急激に電圧が低下するおそれがないにもかかわらず、電池電圧試験を一定の間隔で行っていたため、電池電圧試験のために電池を早期に消耗してしまうことになっていた。 However, when the alarm was activated with a new battery, the battery capacity was sufficient to sound the alarm sound, and there was no risk of a sudden drop in voltage when the alarm sound was sounded. Since the battery voltage test was performed at regular intervals, the battery was consumed at an early stage for the battery voltage test.

The alarm device includes a battery voltage measuring unit that measures the voltage of the battery and a timer, and measures the operating time of the alarm device by the timer and measures the battery voltage by the battery voltage measuring unit. the interval of the battery voltage test that, as the operation time of the alarm after replacing the battery becomes longer, shorter, when the operation time of the alarm device after replacing the battery is less than a predetermined time, the battery voltage test The interval is shortened .
Also, the number of times alarm according to the present invention, the timer Operating the state detecting means counts a predetermined time, which includes a storage unit for storing a number of counts a predetermined time, and measuring a predetermined time Based on the above, the operation time of the alarm device and the interval of the battery voltage test are calculated.

本発明の実施の形態に係る火災警報器の構成を示すブロック図である。It is a block diagram which shows the structure of the fire alarm device which concerns on embodiment of this invention. 本発明の実施の形態に係る火災警報器の動作を示すフローチャートである。It is a flowchart which shows operation | movement of the fire alarm device which concerns on embodiment of this invention.

本実施の形態では、監視領域の煙の濃度に基づき火災判定を行う火災警報器に本発明を適応した場合を例に図1〜2に基づいて説明する。
図1は、本発明の実施の形態に係る火災警報器100の構成を示すブロック図である。図1において、火災警報器100は、電池1と、記憶部2と、試験スイッチ3と、制御部10と、煙検出部20と、表示部30と、音響部40と、電池電圧試験部50とを備える。
電池1は、火災警報器100を動作させるための動作電源を供給する。記憶部2は、火災警報器100を動作させるためのプログラムを格納している。また、記憶部2は、火災警報器100の動作に係わるデータを一時的に格納する図示しない保管領域2aを有する。
試験スイッチ3は、居住者等のユーザによる押下操作を受け付け、点検機構を動作させるためのスイッチである。
制御部10は、定電圧部11と、リセット部12と、発振部13と、タイマ14と、火災判定部15と、電池電圧判定部16とを有していて、記憶部2に格納されているプログラムに従い火災警報器の全体を制御する。
定電圧部11は、電池1の電源電圧を所定の定電圧電源(例えば、約2.3Vの電圧)として制御部10等に供給する。
リセット部12は、電源投入時に制御部10をリセット状態にし、所定時間後にリセット状態を解除して動作可能な初期状態にさせる。また、制御部10に印加される電圧が制御部10の動作保証電圧より小さくなった場合に、制御部10をリセット状態にする。
発振部13は、制御部10に対してクロック信号を供給する。タイマ14は、発振部13のクロック信号に基づき時間を計時し、制御部10が火災警報器100の各部の制御を行うタイミングを発生させる。また、タイマ14は火災警報器100が新しい電池で起動してからどれだけ動作したかの動作時間を計時する。
火災判定部15は、煙検出部20が検出した煙の濃度に基づき火災を判定する。電池電圧判定部16は、電池電圧試験部50が検出した電池の電圧に基づき電池の電圧が正常であるかを判定する。
煙検出部20は、監視領域の状態を検出する状態検出手段であり、発光駆動部21と、発光部22と、受光部23と、受光電流電圧変換部24と、受光増幅部25とで構成される。
発光駆動部21は、限流抵抗とコンデンサを有し、定電圧部11から供給される電源を限流抵抗によって制限して微少な電流(例えば、最大50μA)でコンデンサを充電する。発光駆動部21は、制御部10の制御により、外光を遮断した暗室の内部に配置されたLED等の発光素子である発光部22にコンデンサに蓄えられたエネルギーを供給して発光させる。
受光部23は、光を受光すると電流を流すフォトダイオードであり、暗室の内部の発光部22が照射した光が直接入力しない位置に配置されている。そのため、暗室に煙が流入していないときには、発光部22が照射した光が受光部23には入力されず、暗室に煙が流入したときには、発光部22が照射した光が煙粒子により散乱され、その散乱光が受光部32に入力して受光部23には煙の濃度に応じた電流が流れる。
受光電流電圧変換部24は、受光部23に発生した電流を電圧に変換する。変換された電圧は、微少な電圧であり、そのままでは火災の判断が困難であるため、受光増幅部25で大きな電圧へと増幅する。
火災判定処理は、制御部10が光駆動部21を制御して開始され、受光増幅部25で増幅された電圧を火災判定部15で閾値電圧と比較して、閾値を超えている場合には火災を検出する。
表示部30は、表示灯制御部31と、表示灯32とで構成される。表示灯制御部31は、制御部10の制御によりLED等の発光素子である表示灯32に定電圧部11から電源を供給して表示灯32を火災時には点灯させたり、異常時には点滅させたりする。
音響部40は、音声DA変換部41と、音声増幅部42と、スピーカ43とから構成される。音声DA変換部41は、制御部10に制御されて記憶部2に格納された音声デジタルデータを電圧信号に変換する。音声増幅部42は、変換された電圧信号(音声信号)を増幅して、スピーカ43に印加して、スピーカ43から火災発生や故障発生の警報音を出力させる。
電池電圧試験部50は、疑似電流部51と、電池電圧測定部52とから構成される。疑似電流部51は、一定の電流を流す定電流回路である。電池電圧測定部52は、電池1の電圧をAD変換して電池電圧信号(以下、電池電圧信号と呼ぶ)に変換する。
電池電圧試験は、制御部10が擬似電流部51を制御して開始され、擬似電流部51で火災を警報するときに表示部30と音響部40とで消費される電流と同じ量の警報動作による増加分の電流を流した状態で、電池電圧測定部52が電池1の電圧を変換した電池電圧信号を閾値と比較する。閾値を下回っている場合には電池異常を検出する。
ここで、擬似電流部51で火災を警報する時と同じ量の電流を流して電池電圧試験を行うのは、電池1が終止電圧となっており、火災警報器100が、消費電流が少ない監視動作では電池1が終止電圧を出力して問題なく動作するが、火災の警報を行うと急激に電圧が低下してリセット状態になり、火災を警報できないということがないようにするためである。
次に、火災警報器100の動作について説明する。
火災警報器100は、電池1から電源が供給され定電圧回路11によって所定の定電圧に変換されて制御部10等の各部に供給されると動作を開始する。各部は、制御部10が有するタイマ14が計時したタイミングに応じて制御され動作する。計時したタイミングに応じた動作については図2の火災警報器100の動作を示すフローチャートにより説明する。
まず、火災警報器100は、タイマ14が3秒計時したかを判定して(S1)、3秒計時した場合には、記憶部2の保管領域2aに火災警報器100の動作時間の記録として3秒計時した回数を更新して格納して(S2)、煙検出部20を動作させて火災判定処理を行う(S3)。
火災判定処理の結果が火災を検出したかを判定して(S4)、火災を検出したのであれば、火災表示灯32を点灯(S5)、および、火災発生の警報音をスピーカ43から出力して(S6)、警報動作を行い火災が発生したことを報知する。その後、S1の処理に戻り繰り返し動作を行う。
火災を検出したかの判定で火災を検出していない場合は(S4)、保管領域2aの3秒計時した回数から火災警報器100の動作年数nを算出する(S7)。その後、保管領域2aの3秒計時の回数が所定数÷(n+1)の倍数か判断して(S8)、倍数であれば電池電圧試験部50を作動させて電池電圧試験を行う(S9)。電池電圧試験の結果が電池電圧異常を検出したかを判定して(S10)、電池電圧異常を検出したのであれば、火災表示灯32を点滅(S11)、および、異常発生の警報音をスピーカ43から出力して(S12)、異常が発生したことを報知する。その後、S1の処理に戻り繰り返し動作を行う。
タイマ14が3秒計時したかの判定で3秒を計時していない場合と(S1)、保管領域2aの3秒タイマカウント数が所定数÷(n+1)の倍数であるかの判定でカウント数が倍数ではない場合には(S8)、試験スイッチ3が押下操作されているかを判定して(S13)、押下操作されている場合は、電池電圧試験を行う(S9)、押下操作されていない場合には、S1の処理に戻り繰り返し動作を行う。
ここで、S8の処理である3秒計時の回数が所定数÷(n+1)の倍数であるかの判定について説明する。例えば所定数=4800とすると、火災警報器100の動作年数が1年のときにはS7の処理からn=1となり、3秒計時の回数が2400の倍数毎、つまり、120分に1回のタイミングで電池電圧試験を行い、動作年数が2年のときには、80分に1回、動作年数が3年のときには、60分に1回と、動作年数が少ないときには、電池電圧試験を行う間隔を長くして、動作年数が経過するほど、電池電圧試験を行う間隔を短くするようになっている。
なお、電池1を交換したときには、試験スイッチ3を連続押下操作(例えば10秒間連続で押す)したときに、保管領域2aに格納されている3秒計時した回数をリセットすることができる。
また、本実施の形態では、火災判定処理を行うタイミングである3秒計時の回数で火災警報器100の動作時間を記録したが、タイマ14により、火災警報器100の動作時間のみを別途計時するようにしても良い。
また、本実施の形態では、火災警報器100の動作年数が経過するほど、電池電圧試験を行う間隔を短くしたが、例えば、電池を交換した場合に、新しい電池の初期不良を検出するために、始めの1ヶ月は電池電圧試験の間隔を短くするなど、適宜、火災警報器100の動作時間により電池電圧試験の間隔を変更するようにしても良い。
上記のように、本発明に係わる警報器は、動作電源を供給する電池と、監視領域の状態を検出する状態検出手段と、前記状態検出手段が異常を検出したときに、警報動作を行う警報手段を備えた警報器において、前記警報器は、前記電池の電圧を測定する電池電圧測定部と、タイマとを備え、前記タイマによって警報器の動作時間を計時して、前記電池電圧測定部により電池の電圧をより測定する電池電圧試験の間隔を、警報器の動作時間に応じて変更することを特徴とし、また、本発明に係わる警報器は、さらに警報動作による増加分の電流を流す擬似電流部を備え、前記電池電圧測定部により電池の電圧を測定する際に、前記擬似電流部で電流を流すことを特徴とし、また、本発明に係わる警報器は、前記電池電圧試験の間隔を警報器の動作時間が長くなるほど、短くすることを特徴とするため、電池の使用時間に応じて電池電圧試験を行うことができるので、電池電圧試験のために、電池を早期に消耗するということがない。
In the present embodiment, a case where the present invention is applied to a fire alarm device that makes a fire determination based on the smoke concentration in the monitoring area will be described with reference to FIGS.
FIG. 1 is a block diagram showing a configuration of a fire alarm device 100 according to an embodiment of the present invention. In FIG. 1, a fire alarm 100 includes a battery 1, a storage unit 2, a test switch 3, a control unit 10, a smoke detection unit 20, a display unit 30, an acoustic unit 40, and a battery voltage test unit 50. With.
The battery 1 supplies operating power for operating the fire alarm 100. The storage unit 2 stores a program for operating the fire alarm device 100. The storage unit 2 also has a storage area 2a (not shown) that temporarily stores data related to the operation of the fire alarm device 100.
The test switch 3 is a switch for accepting a pressing operation by a user such as a resident and operating an inspection mechanism.
The control unit 10 includes a constant voltage unit 11, a reset unit 12, an oscillation unit 13, a timer 14, a fire determination unit 15, and a battery voltage determination unit 16, and is stored in the storage unit 2. The whole fire alarm is controlled according to the program.
The constant voltage unit 11 supplies the power supply voltage of the battery 1 to the control unit 10 or the like as a predetermined constant voltage power source (for example, a voltage of about 2.3 V).
The reset unit 12 puts the control unit 10 into a reset state when the power is turned on, and releases the reset state after a predetermined time to make it an operable initial state. In addition, when the voltage applied to the control unit 10 becomes smaller than the operation guarantee voltage of the control unit 10, the control unit 10 is reset.
The oscillation unit 13 supplies a clock signal to the control unit 10. The timer 14 measures time based on the clock signal of the oscillating unit 13, and generates a timing at which the control unit 10 controls each unit of the fire alarm device 100. In addition, the timer 14 measures the operation time of how long the fire alarm 100 has been operated since it was started with a new battery.
The fire determination unit 15 determines a fire based on the smoke concentration detected by the smoke detection unit 20. The battery voltage determination unit 16 determines whether the battery voltage is normal based on the battery voltage detected by the battery voltage test unit 50.
The smoke detection unit 20 is a state detection unit that detects the state of the monitoring region, and includes a light emission drive unit 21, a light emission unit 22, a light reception unit 23, a light reception current voltage conversion unit 24, and a light reception amplification unit 25. Is done.
The light emission drive unit 21 includes a current limiting resistor and a capacitor, and the power supplied from the constant voltage unit 11 is limited by the current limiting resistor to charge the capacitor with a minute current (for example, 50 μA at the maximum). Under the control of the control unit 10, the light emission driving unit 21 supplies the light stored in the capacitor to the light emitting unit 22, which is a light emitting element such as an LED, disposed inside the dark room where external light is blocked, and causes the light to emit light.
The light receiving unit 23 is a photodiode that causes a current to flow when receiving light, and is disposed at a position where the light emitted from the light emitting unit 22 inside the dark room is not directly input. Therefore, when the smoke does not flow into the dark room, the light irradiated by the light emitting unit 22 is not input to the light receiving unit 23, and when the smoke flows into the dark room, the light irradiated by the light emitting unit 22 is scattered by the smoke particles. The scattered light is input to the light receiving unit 32, and a current corresponding to the smoke concentration flows through the light receiving unit 23.
The light reception current voltage converter 24 converts the current generated in the light receiver 23 into a voltage. Since the converted voltage is a minute voltage and it is difficult to determine a fire as it is, the light receiving amplification unit 25 amplifies the voltage to a large voltage.
The fire determination process is started when the control unit 10 controls the light driving unit 21, and the voltage amplified by the light receiving amplification unit 25 is compared with the threshold voltage by the fire determination unit 15. Detect fire.
The display unit 30 includes an indicator lamp control unit 31 and an indicator lamp 32. The indicator lamp control unit 31 supplies power from the constant voltage unit 11 to the indicator lamp 32, which is a light emitting element such as an LED, under the control of the controller 10 to turn on the indicator lamp 32 in the event of a fire or to blink in the event of an abnormality. .
The acoustic unit 40 includes an audio DA conversion unit 41, an audio amplification unit 42, and a speaker 43. The audio DA conversion unit 41 is controlled by the control unit 10 to convert audio digital data stored in the storage unit 2 into a voltage signal. The audio amplifying unit 42 amplifies the converted voltage signal (audio signal), applies the amplified voltage signal to the speaker 43, and causes the speaker 43 to output a warning sound indicating the occurrence of a fire or failure.
The battery voltage test unit 50 includes a pseudo current unit 51 and a battery voltage measurement unit 52. The pseudo current unit 51 is a constant current circuit that allows a constant current to flow. The battery voltage measuring unit 52 performs AD conversion on the voltage of the battery 1 and converts it into a battery voltage signal (hereinafter referred to as a battery voltage signal).
The battery voltage test is started by the control unit 10 controlling the pseudo current unit 51, and when the pseudo current unit 51 alarms a fire, an alarm operation of the same amount as the current consumed by the display unit 30 and the acoustic unit 40 The battery voltage measurement unit 52 compares the battery voltage signal obtained by converting the voltage of the battery 1 with a threshold value in a state in which the increased current is supplied. If it is below the threshold, a battery abnormality is detected.
Here, the battery voltage test is performed by supplying the same amount of current as that when the fire is alarmed by the pseudo-current unit 51, because the battery 1 is at the end voltage, and the fire alarm 100 is monitored with less current consumption. In operation, the battery 1 outputs the end voltage and operates without any problem. However, when a fire alarm is issued, the voltage is suddenly reduced to a reset state so that the fire cannot be alarmed.
Next, the operation of the fire alarm 100 will be described.
The fire alarm device 100 starts operating when power is supplied from the battery 1, converted into a predetermined constant voltage by the constant voltage circuit 11, and supplied to each unit such as the control unit 10. Each unit is controlled and operated according to the timing counted by the timer 14 included in the control unit 10. The operation in accordance with the timed timing will be described with reference to the flowchart showing the operation of the fire alarm 100 in FIG.
First, the fire alarm device 100 determines whether or not the timer 14 has timed for 3 seconds (S1), and when it has timed for 3 seconds, the fire alarm device 100 records the operation time of the fire alarm device 100 in the storage area 2a of the storage unit 2. The number of times counted for 3 seconds is updated and stored (S2), and the smoke detection unit 20 is operated to perform a fire determination process (S3).
It is determined whether or not a fire is detected as a result of the fire determination process (S4). If a fire is detected, the fire indicator lamp 32 is turned on (S5), and a fire alarm is output from the speaker 43. (S6), an alarm operation is performed to notify that a fire has occurred. After that, the process returns to S1 and repeats the operation.
If it is determined whether or not a fire has been detected (S4), the number of years n of operation of the fire alarm device 100 is calculated from the number of times the storage area 2a has been counted for 3 seconds (S7). Thereafter, it is determined whether the count of the storage area 2a for 3 seconds is a multiple of the predetermined number / (n + 1) (S8). If it is a multiple, the battery voltage test unit 50 is operated to perform a battery voltage test (S9). It is determined whether or not the battery voltage test has detected a battery voltage abnormality (S10). If a battery voltage abnormality is detected, the fire indicator lamp 32 blinks (S11), and an alarm sound indicating the occurrence of the abnormality is speaker. 43 (S12) to notify that an abnormality has occurred. After that, the process returns to S1 and repeats the operation.
If the timer 14 has not timed 3 seconds (S1), and if the 3-second timer count in the storage area 2a is a multiple of a predetermined number ÷ (n + 1) Is not a multiple (S8), it is determined whether the test switch 3 is pressed (S13). If the switch is pressed, a battery voltage test is performed (S9), and the switch is not pressed. In that case, the process returns to the process of S1 and repeats the operation.
Here, the determination of whether the number of times measured for 3 seconds, which is the process of S8, is a multiple of the predetermined number ÷ (n + 1) will be described. For example, if the predetermined number = 4800, when the fire alarm 100 is operated for one year, n = 1 from the process of S7, and the number of times for 3 seconds is every multiple of 2400, that is, once every 120 minutes. A battery voltage test is performed. When the operation years is 2, the interval between battery voltage tests is increased when the operation years are low, such as once every 80 minutes, once every 60 minutes, when the operation years is three years. As the operation years elapse, the battery voltage test interval is shortened.
When the battery 1 is replaced, when the test switch 3 is continuously pressed (for example, continuously pressed for 10 seconds), the number of times counted for 3 seconds stored in the storage area 2a can be reset.
In this embodiment, the operation time of the fire alarm device 100 is recorded by the number of times of 3 seconds, which is the timing for performing the fire determination process, but only the operation time of the fire alarm device 100 is separately measured by the timer 14. You may do it.
Moreover, in this Embodiment, the interval which performs a battery voltage test was shortened, so that the years of operation | movement of the fire alarm device 100 passed, but in order to detect the initial failure of a new battery, for example, when a battery is replaced | exchanged. The battery voltage test interval may be appropriately changed depending on the operation time of the fire alarm 100, such as shortening the battery voltage test interval in the first month.
As described above, the alarm device according to the present invention includes a battery that supplies operation power, a state detection unit that detects a state of a monitoring area, and an alarm that performs an alarm operation when the state detection unit detects an abnormality. In the alarm device comprising the means, the alarm device includes a battery voltage measuring unit that measures the voltage of the battery, and a timer. The timer measures the operating time of the alarm device, and the battery voltage measuring unit The interval of the battery voltage test for measuring the battery voltage is changed according to the operating time of the alarm device. The alarm device according to the present invention further simulates an increase in current due to the alarm operation. A current section, and when the battery voltage measuring section measures the voltage of the battery, the pseudo-current section allows current to flow, and the alarm device according to the present invention provides an interval between the battery voltage tests.
