It is sufficient to provide a filter circuit for extracting a control voltage supplied superimposed on the communication line 31.

検知部給電制御部１３３は、給電線３３を介して検知部給電部１５に供給される制御電圧によって検知部１０の制御を開始、実行し、前記制御電圧の供給が停止されると検知部１０の制御を停止するように構成されている。 The detection unit power supply control unit 133 starts and executes the control of the detection unit 10 by the control voltage supplied to the detection unit power supply unit 15 through the power supply line 33, and when the supply of the control voltage is stopped, the detection unit 10 It is configured to stop the control.

演算処理部１１１は、ガスセンサ１１の電圧レベルを監視し、該電圧レベルが所定の警報閾値以上を継続して検知すると、ガスセンサ１１がＬＰガスの漏洩を検知したと判断する。なお、演算処理部１１１は、ガスセンサ１１の電圧レベルから、所定周期ごとにＬＰガス濃度を算出し、算出したＬＰガス濃度が、所定の警報レベル閾値以上、かつ、所定の時間継続して検知した場合にＬＰガスの漏洩と判断するように構成してもよい。 The arithmetic processing unit 111 monitors the voltage level of the gas sensor 11 and determines that the gas sensor 11 has detected a leak of LP gas when the voltage level continues to be detected above a predetermined alarm threshold. The arithmetic processing unit 111 calculates the LP gas concentration for each predetermined period from the voltage level of the gas sensor 11, and the calculated LP gas concentration is continuously detected for a predetermined time for a predetermined alarm level threshold or more. In some cases, it may be determined that LP gas is leaked.

第一報知制御部１１２は、ガスセンサ１１によるＬＰガスの漏洩等の異常検知情報や、検知部１０側の機器情報や、後述する警報部２０から送信される警報部２０側の機器情報や、警報部２０に備えられた操作処理部２２３からの信号に基づいて、第一報知部１２による報知を制御する。 The first notification control unit 112 detects abnormality detection information such as LP gas leakage by the gas sensor 11, device information on the detection unit 10 side, device information on the alarm unit 20 side transmitted from the alarm unit 20 described later, Based on a signal from the operation processing unit 223 provided in the unit 20, notification by the first notification unit 12 is controlled.

The operation confirmation lamp is configured to include green and red LEDs. For example, if the alarm device 1 is in a normal state, it is lit in green, and if it is in an abnormality detection state such as LP gas leakage, it is lit in red. If it is in the state, it can be easily identified by changing the light emission pattern such as lighting, blinking, and extinguishing and the combination of the light emission colors such as green and red according to the state.

第一通信部１３１は、後述する警報部２０の第二通信部２３１と有線３０である通信線３１によって電気的に接続され、ＵＡＲＴで実現される５００ｂｐｓの調歩同期方式によるシリアル通信によって、検知部１０側の機器情報を第二通信部２３１へと送信するとともに、警報部２０側の機器情報を第二通信部２３１から受信するように構成されている。この、第一通信部１３１から第二通信部２３１への検知部１０側の機器情報の通信を検知部通信という。なお、検知部通信は、調歩同期方式によるシリアル通信で行われる構成に限らず、通信線３１の他にクロック信号を送信するクロック線を備えて、同期式のシリアル通信で行われる構成であってもよい。 The first communication unit 131 is electrically connected to a second communication unit 231 of the alarm unit 20 to be described later by a communication line 31 that is a wired 30 and is detected by serial communication using a 500 bps asynchronous process realized by UART. The device information on the 10th side is transmitted to the second communication unit 231 and the device information on the alarm unit 20 side is received from the second communication unit 231. This communication of device information on the detection unit 10 side from the first communication unit 131 to the second communication unit 231 is referred to as detection unit communication. Note that the detection unit communication is not limited to the configuration that is performed by serial communication using the asynchronous method, but includes a clock line that transmits a clock signal in addition to the communication line 31, and is configured to be performed by synchronous serial communication. Also good.

It consists of a packet of several bytes consisting of data with bits, parity bits, and stop bits added, and data such as other parameters.

第一通信制御部１３２は、所定のタイミングで検知部通信を実行するように構成されている。該検知部通信の通信タイミングの詳細は後述する。 The first communication control unit 132 is configured to execute detection unit communication at a predetermined timing. Details of the communication timing of the detection unit communication will be described later.

The determination result is stored. Further, device information on the detection unit 10 side transmitted to the alarm unit 20 and device information on the alarm unit 20 side received by alarm unit communication described later are also stored.

To communicate bidirectionally with the operation processing unit 223 that processes the input signal from the unit 23, the second notification control unit 222 that controls notification by the second notification unit 22 based on the signal from the operation processing unit 223, and the detection unit 10. The second communication unit 231 connected to the communication line 31 as the wire 30, the second communication control unit 232 that controls the second communication unit 231, and the control voltage from the alarm unit power supply unit 25 to the detection unit power supply unit 15. The alarm unit power supply control unit 233 for controlling start / stop of power transmission, the device information on the alarm unit 20 side, and the device information on the detection unit 10 side received by the detection unit communication are described. A function block, such as the second storage unit 201 is configured to.

警報報知制御部２２１は、検知部１０から受信した検知部通信に含まれるＬＰガスの漏洩検知を伝えるガス警報フラグに基づいて、警報報知部２１による警報の報知を実行する。また、警報報知制御部２２１は、ガスセンサに検知対象のＬＰガスの漏洩等の外部環境の異常が検出されていない状態で、操作部２３の長押し、短押し等の所定の操作に応じた操作処理部２２３からの信号に基づいて、警報部２０の各機能が正常に作動しているか否かの点検結果を警報報知部２１としてのスピーカから警報音を例えば１フレーズ鳴らすことによって報知することもできる。 The alarm notification control unit 221 performs alarm notification by the alarm notification unit 21 based on the gas alarm flag that conveys the detection of leakage of LP gas included in the detection unit communication received from the detection unit 10. Further, the alarm notification control unit 221 performs an operation corresponding to a predetermined operation such as a long press or a short press of the operation unit 23 in a state where an abnormality of the external environment such as leakage of LP gas to be detected is not detected by the gas sensor. Based on the signal from the processing unit 223, the inspection result as to whether or not each function of the alarm unit 20 is operating normally can be notified by sounding an alarm sound from the speaker as the alarm notification unit 21, for example. it can.

第二報知制御部２２２は、検知部１０から送信されるガスセンサ１１によるＬＰガスの漏洩等の異常検知情報を含む検知部１０側の機器情報や、警報部２０側の機器情報や、警報部２０に備えられた操作処理部２２３からの信号に基づいて、第二報知部２２を制御する。 The second notification control unit 222 includes device information on the detection unit 10 side, including abnormality detection information such as LP gas leakage by the gas sensor 11 transmitted from the detection unit 10, device information on the alarm unit 20 side, and the alarm unit 20. The second notification unit 22 is controlled on the basis of a signal from the operation processing unit 223 included in the control unit 223.

第二報知部２２としての動作確認ランプは、警報器１の正常、ＬＰガスの漏洩等の異常検知、故障等の状態を、所定の態様によって報知するように構成されている。該動作確認ランプは緑色及び赤色のＬＥＤを備えて構成され、例えば、警報器１が正常状態であれば緑色に点灯し、ＬＰガスの漏洩等の異常検知状態であれば赤色に点灯し、故障状態であれば緑色に点滅するように、その状態に応じて点灯、点滅、消灯等の発光パターンや、緑色、赤色等の発光色の組み合わせを変更することで識別を容易にすることができる。 The operation check lamp as the second notification unit 22 is configured to notify the normal state of the alarm device 1, abnormality detection such as LP gas leakage, and the like in a predetermined manner. The operation confirmation lamp is configured to include green and red LEDs. For example, if the alarm device 1 is in a normal state, it is lit in green, and if it is in an abnormality detection state such as LP gas leakage, it is lit in red. If it is in the state, it can be easily identified by changing the light emission pattern such as lighting, blinking, and extinguishing and the combination of the light emission colors such as green and red according to the state.

操作部２３としてのスイッチは、外部からの操作に応じて開又は閉動作するように構成されるとともに、外部から視認可能な位置に第二報知部２２としての動作確認ランプを内蔵している。操作処理部２２３は、操作者が操作部２３を長押し、短押し等の所定の操作したことを検出し、それに応じて予め設定された所定のプログラムを実行する。例えば、操作部２３の操作に応じて、警報器１が正常に動作するか否かを確認する点検動作を実行する。 The switch as the operation unit 23 is configured to open or close in response to an operation from the outside, and incorporates an operation confirmation lamp as the second notification unit 22 at a position that can be visually recognized from the outside. The operation processing unit 223 detects that the operator has performed a predetermined operation such as a long press or a short press on the operation unit 23, and executes a predetermined program set in advance accordingly. For example, according to the operation of the operation unit 23, an inspection operation for confirming whether or not the alarm device 1 operates normally is executed.

第二報知制御部２２２は、ガスセンサに検知対象のＬＰガスの漏洩等の外部環境の異常が検出されていない状態で、操作部２３の長押し、短押し等の所定の操作に応じた操作処理部２２３からの信号に基づいて、警報部２０の各機能が正常に作動しているか否かの点検結果を第二報知部２２としての動作確認ランプの点灯によって報知することもできる。 The second notification control unit 222 performs an operation process corresponding to a predetermined operation such as a long press or a short press of the operation unit 23 in a state where an abnormality of the external environment such as leakage of LP gas to be detected is not detected by the gas sensor. Based on the signal from the unit 223, the inspection result as to whether or not each function of the alarm unit 20 is operating normally can be notified by turning on the operation confirmation lamp as the second notification unit 22.

操作処理部２２３は、第二報知制御部２２２及び警報報知制御部２２１と接続されるとともに、第二通信部２３１、通信線３１及び第一通信部１３１を介して第一報知制御部１１２と接続され、操作部２３の操作に基づいて、第二報知制御部２２２及び警報報知制御部２２１に第二報知部２２及び警報報知部２１による警報器１の状態の報知を実行させるとともに、第一報知制御部１１２に第一報知部１２による警報器１の状態の報知を実行させるように構成されている。 The operation processing unit 223 is connected to the second notification control unit 222 and the alarm notification control unit 221 and connected to the first notification control unit 112 via the second communication unit 231, the communication line 31, and the first communication unit 131. Based on the operation of the operation unit 23, the second notification control unit 222 and the alarm notification control unit 221 execute the notification of the state of the alarm device 1 by the second notification unit 22 and the alarm notification unit 21, and the first notification The control unit 112 is configured to cause the first notification unit 12 to notify the state of the alarm device 1.

第二通信部２３１は、第一通信部１３１と有線３０である通信線３１によって電気的に接続され、ＵＡＲＴで実現される５００ｂｐｓの調歩同期方式によるシリアル通信によって、警報部２０側の機器情報を第一通信部１３１へと送信するとともに、検知部１０側の機器情報を第一通信部１３１から受信するように構成されている。この、第二通信部２３１から第一通信部１３１への警報部２０側の機器情報の通信を警報部通信という。なお、警報部通信は、調歩同期方式によるシリアル通信で行われる構成に限らず、通信線３１の他にクロック信号を送信するクロック線を備えて、同期式のシリアル通信で行われる構成であってもよい。 The second communication unit 231 is electrically connected to the first communication unit 131 through the communication line 31 that is the wired 30, and device information on the alarm unit 20 side is obtained by serial communication using a 500 bps asynchronous system realized by UART. While transmitting to the 1st communication part 131, it is comprised so that the apparatus information by the side of the detection part 10 may be received from the 1st communication part 131. FIG. This communication of device information on the alarm unit 20 side from the second communication unit 231 to the first communication unit 131 is referred to as alarm unit communication. Note that the alarm unit communication is not limited to the configuration that is performed by serial communication using the start-stop synchronization method, but includes a clock line that transmits a clock signal in addition to the communication line 31, and is configured to be performed by synchronous serial communication. Also good.

警報部２０側の機器情報は、例えば、警報部２０の故障を伝える警報部故障フラグ、検知部１０の第一報知部１２の確認のための確認機能フラグ等を含んで構成される数ビットのデータにスタートビット、パリティビット、ストップビットが付加されたデータと、その他のパラメータ等のデータからなる数バイトのパケットで構成されている。 The device information on the alarm unit 20 side includes, for example, an alarm unit failure flag that conveys a failure of the alarm unit 20, a confirmation function flag for confirmation of the first notification unit 12 of the detection unit 10, and the like. It consists of a packet of several bytes consisting of data with start bit, parity bit and stop bit added to the data and data such as other parameters.

第二通信制御部２３２は、所定のタイミングで警報部通信を実行するように構成されている。該警報部通信の通信タイミングの詳細は後述する。 The second communication control unit 232 is configured to execute alarm unit communication at a predetermined timing. Details of the communication timing of the alarm unit communication will be described later.

第二記憶部２０１は、検知部１０へと送信する警報部２０側の機器情報や、検知部通信によって受信した検知部１０側の機器情報も記憶する。ただし、記憶対象の機器情報にパリティチェックエラー、通信エラー、チェックサムエラー等のエラーが認められた場合は、該機器情報は記憶しないように構成してもよい。 The second storage unit 201 also stores device information on the alarm unit 20 side transmitted to the detection unit 10 and device information on the detection unit 10 side received by detection unit communication. However, when an error such as a parity check error, a communication error, or a checksum error is recognized in the device information to be stored, the device information may not be stored.

次に、検知部１０と警報部２０の間で双方向に実行される検知部通信及び警報部通信について説明する。
検知部通信と警報部通信は、第一通信部１３１と第二通信部２３１を接続する１本の通信線３１によって実行されるため、検知部通信と警報部通信が同時に実行された場合は、正常な通信をすることができない。そこで、警報器１を起動すると、まず第一通信制御部１３２によって検知部通信が実行されるように構成されている。 Next, detection unit communication and alarm unit communication executed bi-directionally between the detection unit 10 and the alarm unit 20 will be described.
Since the detection unit communication and the alarm unit communication are executed by one communication line 31 connecting the first communication unit 131 and the second communication unit 231, when the detection unit communication and the alarm unit communication are executed simultaneously, Normal communication is not possible. Therefore, when the alarm device 1 is activated, the first communication control unit 132 first performs detection unit communication.

図３に示すように、警報器１に電源投入後、所定の時間例えば１秒経過後に、まず第一通信制御部１３２は検知部１０側の機器情報を第一記憶部１０１に記憶させるとともに検知部通信を実行する。第二通信制御部２３２は検知部通信を受信するとこれを第二記憶部２０１に記憶させ、検知部通信の受信後の所定の時間例えば１００ミリ秒経過後に警報部通信を実行する。第一通信制御部１３２は警報部信号を受信するとこれを第一記憶部１０１に記憶させ、警報部通信の受信後の所定の時間例えば１００ミリ秒経過後に検知部通信を実行する。このように第一通信制御部１３２及び第二通信制御部２３２は、検知部通信と警報部通信とを所定タイミングで交互に実行して、検知対象であるＬＰガスの漏洩を監視しながら、機器の状態も相互に監視する。 As shown in FIG. 3, after the alarm device 1 is powered on, after a predetermined time, for example, 1 second has elapsed, the first communication control unit 132 first stores the device information on the detection unit 10 side in the first storage unit 101 and detects it. Department communication. When the second communication control unit 232 receives the detection unit communication, the second communication control unit 232 stores the detection unit communication in the second storage unit 201, and executes the alarm unit communication after elapse of a predetermined time, for example, 100 milliseconds after reception of the detection unit communication. When the first communication control unit 132 receives the alarm unit signal, the first communication control unit 132 stores the alarm unit signal in the first storage unit 101, and executes the detection unit communication after elapse of a predetermined time, for example, 100 milliseconds after reception of the alarm unit communication. As described above, the first communication control unit 132 and the second communication control unit 232 alternately execute the detection unit communication and the alarm unit communication at a predetermined timing, and monitor the leakage of the LP gas that is the detection target. Also monitor the state of each other.

検知部１０がＬＰガスの漏洩を検出すると、検知部通信で送信する検知部１０側の機器情報にＬＰガスの漏洩検知を伝えるガス警報フラグを立てる。警報部２０の警報部制御部２００は、受信した検知部通信にガス警報フラグが立っていると、警報報知制御部２２１が警報報知部２１を制御して、「ガスが漏れていませんか」等の合成音によって、ＬＰガスの漏洩を報知する。このとき、検知部１０及び警報部２０のそれぞれの動作確認ランプ（第一報知部１２及び第二報知部２２）を赤色に点灯させることで、ＬＰガスの漏洩の発生を視覚的に報知することもできる。 When the detection unit 10 detects a leak of LP gas, a gas alarm flag is set to notify the detection of the leak of LP gas in the device information on the detection unit 10 side transmitted by detection unit communication. When the gas alarm flag is set in the received detector communication, the alarm control unit 200 of the alarm unit 20 controls the alarm notification unit 221 so that “gas is not leaking”. The LP gas leakage is notified by a synthesized sound such as. At this time, the operation check lamps (the first notification unit 12 and the second notification unit 22) of the detection unit 10 and the alarm unit 20 are lit in red to visually notify the occurrence of LP gas leakage. You can also.

検知部１０及び警報部２０は、検知部通信と警報部通信の交互の通信を実行するなかで、自己の故障を検知すると自己の動作確認ランプ（第一報知部１２又は第二報知部２２）を緑色に点滅させるとともに、検知部通信や警報部通信によって自己の故障を他方に通信する。該検知部通信を受信した警報部２０や、該警報部通信を受信した検知部１０は、他方の故障の発生に基づき自己の動作確認ランプ（第一報知部１２又は第二報知部２２）を緑色に点滅させる。なお、何れの機器に故障が発生したかによって、動作確認ランプ（第一報知部１２及び第二報知部２２）の発光パターンをその周期や強度を異ならせることで、あるいはスピーカ（警報報知部２１）から異なる合成音、例えば「警報部故障です」、「検知部故障です」のように通知することで、何れの機器に故障が発生したかの確認が容易となる。 The detection unit 10 and the alarm unit 20 perform their own operation check lamps (the first notification unit 12 or the second notification unit 22) when detecting their own failure while performing alternate communication of the detection unit communication and the alarm unit communication. Blinks in green and communicates its own fault to the other through detection unit communication and alarm unit communication. The alarm unit 20 that has received the detection unit communication and the detection unit 10 that has received the alarm unit communication have their own operation confirmation lamps (the first notification unit 12 or the second notification unit 22) based on the occurrence of the other failure. Flashes green. Depending on which device has failed, the light emission pattern of the operation confirmation lamp (the first notification unit 12 and the second notification unit 22) is changed in the period and intensity, or the speaker (alarm notification unit 21). ) From different synthesized sounds, such as “alarm unit failure” and “detection unit failure”, it becomes easy to confirm which device has failed.

図４に示すように、検知部１０及び警報部２０は、検知部通信と警報部通信の交互の通信を実行するなかで、警報部２０が検知部１０からの検知部通信を受信しない場合に、第二通信制御部２３２は内部に備えたタイマーを起動しタイムアップするまで検知部通信の受信を待ち続ける。 As shown in FIG. 4, when the detection unit 10 and the alarm unit 20 execute alternating communication of detection unit communication and alarm unit communication, the alarm unit 20 does not receive the detection unit communication from the detection unit 10. The second communication control unit 232 waits for reception of the detection unit communication until the timer provided therein is activated and the time is up.

タイマーで設定された所定の時間例えば１８０秒以内に検知部通信の受信をすると、その後上述のように１００ミリ秒の経過後に警報部通信を実行する。該タイマーで設定された１８０秒以内に検知部通信が正常に受信されない通信エラーが繰り返されると警報部２０は、検知部１０又は警報部２０の異常を判断し、動作確認ランプによって故障状態を報知する。なお、前記１８０秒という時間は検知部１０又は警報部２０の故障によりＬＰガスの漏洩の監視又はその報知ができない時間が短すぎず長すぎない時間の例示である。 When the detection unit communication is received within a predetermined time set by the timer, for example, 180 seconds, the alarm unit communication is executed after 100 milliseconds have elapsed as described above. When a communication error is detected in which the detection unit communication is not normally received within 180 seconds set by the timer, the alarm unit 20 determines the abnormality of the detection unit 10 or the alarm unit 20, and notifies the failure state by the operation check lamp. To do. The time of 180 seconds is an example of a time in which the LP gas leakage cannot be monitored or notified due to a failure of the detection unit 10 or the alarm unit 20 and is not too short or too long.

検知部１０及び警報部２０は、検知部通信と警報部通信の交互の通信を実行するなかで、検知部１０が警報部２０からの警報部通信を受信しない場合に、第一通信制御部１３１は内部に備えたタイマーを起動しタイムアップするまで警報部通信の受信を待ち続ける。なおこのとき、検知部１０は前回送信した検知部１０側の機器情報に基づく検知部通信を１秒ごとに繰り返し実行してもよい。警報部２０の故障により警報部通信が正常に送信されない、又は検知部１０の故障により警報部通信を正常に受信できない場合の他に、警報部２０の故障により前回送信した検知部通信が警報部２０に正常に受信されないために警報部２０からの警報部通信がされない可能性があるためである。 The detection unit 10 and the alarm unit 20 perform the first communication control unit 131 when the detection unit 10 does not receive the alarm unit communication from the alarm unit 20 while performing the alternating communication of the detection unit communication and the alarm unit communication. Keeps waiting for reception of the alarm unit communication until the internal timer is started and the time is up. At this time, the detection unit 10 may repeatedly execute detection unit communication based on device information on the detection unit 10 side transmitted last time every second. In addition to the case where the alarm unit communication is not normally transmitted due to the failure of the alarm unit 20, or the alarm unit communication cannot be normally received due to the failure of the detection unit 10, the detection unit communication transmitted last time due to the failure of the alarm unit 20 is This is because there is a possibility that the alarm unit communication from the alarm unit 20 may not be performed because the alarm unit 20 is not normally received.

タイマーで設定された所定の時間例えば１８０秒以内に警報部通信の受信をすると、その後上述のように１００ミリ秒の経過後に検知部通信を実行する。該タイマーで設定された１８０秒以内に警報部通信が正常に受信されない通信エラーが繰り返されると検知部１０は検知部１０又は警報部２０の異常を判断し、動作確認ランプによって故障状態を報知する。なお、前記１８０秒という時間は検知部又は警報部の故障によりＬＰガスの漏洩の監視又はその報知ができない時間が短すぎず長すぎない時間の例示である。 When the alarm unit communication is received within a predetermined time set by the timer, for example, 180 seconds, the detection unit communication is executed after 100 milliseconds have elapsed as described above. If a communication error in which the alarm unit communication is not normally received within 180 seconds set by the timer is repeated, the detection unit 10 determines the abnormality of the detection unit 10 or the alarm unit 20, and notifies the failure state by the operation check lamp. . The time of 180 seconds is an example of a time in which the LP gas leakage cannot be monitored or notified due to a failure of the detection unit or the alarm unit and is not too short or too long.

なお、上述のように、警報器１の電源投入をすると、１秒経過後にまず第一通信制御部１３２が初回の検知部通信を実行する。警報部２０は、この電源投入直後に限り、検知部通信の受信の有無による異常の判断の待ち時間が１０秒に設定されている。前記１０秒という時間は、警報器１の電源投入した後に、検知部１０と警報部２０との通信が正常に実行されているか否かの判断をするのに短すぎず長すぎない時間の例示である。なお、検知部１０は、初回の検知部通信後、初回に送信した検知部１０側の機器情報に基づく検知部通信を１秒ごとに繰り返し実行してもよい。 As described above, when the alarm device 1 is powered on, the first communication control unit 132 first executes the first detection unit communication after 1 second has elapsed. The alarm unit 20 is set to have a waiting time of 10 seconds for abnormality determination based on the presence or absence of detection unit communication only immediately after the power is turned on. The time of 10 seconds is an example of a time that is not too short and not too long to determine whether or not the communication between the detection unit 10 and the alarm unit 20 is normally performed after the alarm device 1 is turned on. It is. In addition, the detection part 10 may repeatedly perform the detection part communication based on the apparatus information by the side of the detection part 10 transmitted for the first time after 1st detection part communication.

検知部１０又は警報部２０の故障が発見された場合は、該故障した検知部１０又は警報部２０を新たな機器と交換することになる。このとき故障した検知部１０の第一記憶部１０１又は故障した警報部２０の第二記憶部２０１には、検知部１０側の機器情報及び警報部２０側の機器情報の双方が記憶されているため、回収した機器の第一記憶部１０１又は第二記憶部２０１の何れかを確認することで、故障の発見までに記憶した検知部１０及び警報部２０の動作の履歴を確認することができ、その故障の発生時期や発生原因を特定することが可能となる。すなわち、本発明による警報器によれば、検知部又は警報部の故障を容易に発見でき、その故障の発生時期や発生原因を把握することができるようになった。 When a failure of the detection unit 10 or the alarm unit 20 is found, the failed detection unit 10 or the alarm unit 20 is replaced with a new device. At this time, both the device information on the detection unit 10 side and the device information on the alarm unit 20 side are stored in the first storage unit 101 of the failed detection unit 10 or the second storage unit 201 of the failed alarm unit 20. Therefore, by confirming either the first storage unit 101 or the second storage unit 201 of the collected device, it is possible to confirm the history of operations of the detection unit 10 and the alarm unit 20 stored until the failure is discovered. It becomes possible to specify the occurrence time and cause of the failure. That is, according to the alarm device of the present invention, a failure of the detection unit or the alarm unit can be easily found, and the occurrence timing and cause of the failure can be grasped.

上述した実施形態では、警報部２０が備える操作部２３としてのスイッチが、第二報知部２２としての動作確認ランプを内蔵している構成のものを説明したが、操作部２３と第二報知部２２をそれぞれ別体に構成し、第二報知部２２は警報部２０のケーシングの外部から視認が容易な位置に備え、操作部２３は警報部２０のケーシングの外部から操作が容易な位置に備える構成であってもよい。 In the above-described embodiment, the switch as the operation unit 23 included in the alarm unit 20 has a configuration in which the operation check lamp as the second notification unit 22 is built in. However, the operation unit 23 and the second notification unit are described. 22 are configured separately, the second notification unit 22 is provided at a position that is easily visible from the outside of the casing of the alarm unit 20, and the operation unit 23 is provided at a position that is easy to operate from the outside of the casing of the alarm unit 20. It may be a configuration.

上述した実施形態では、警報部２０が操作部２３及び操作処理部２２３を備える構成について説明したがこれに限らない。操作部２３及び操作処理部２２３は、検知部１０のみに備える構成や、検知部１０及び警報部２０のそれぞれに備える構成であってもよい。検知部１０側の操作部を操作することで、検知部１０の第一報知部１２及び警報部２０の第二報知部２２から警報器１の状態の報知が可能となる。 In the embodiment described above, the configuration in which the alarm unit 20 includes the operation unit 23 and the operation processing unit 223 has been described, but the configuration is not limited thereto. The operation unit 23 and the operation processing unit 223 may have a configuration provided only in the detection unit 10 or a configuration provided in each of the detection unit 10 and the alarm unit 20. By operating the operation unit on the detection unit 10 side, the state of the alarm device 1 can be notified from the first notification unit 12 of the detection unit 10 and the second notification unit 22 of the alarm unit 20.

上述した実施形態では、警報報知部２１がスピーカである場合について説明したが、警報報知部２１は、スピーカに替えて、又は加えて、警報ブザーや警報ランプであってもよく、スピーカによる警報音に替えて、又は加えて、警報ブザーの鳴動や、警報ランプの点灯、点滅、消灯等によって、ＬＰガスの漏洩を報知する構成であってもよい。 In the embodiment described above, the case where the alarm notification unit 21 is a speaker has been described, but the alarm notification unit 21 may be an alarm buzzer or an alarm lamp instead of or in addition to the speaker. Instead of or in addition, a configuration may be adopted in which LP gas leakage is notified by sounding an alarm buzzer, turning on, blinking, or turning off an alarm lamp.

警報報知部２１として警報ランプを採用する場合は、該警報ランプと第二報知部２２としての動作確認ランプと兼用して、それぞれ点灯、点滅、消灯等の発光パターンや、緑色、赤色等の発光色の組み合わせを変更することにより、警報報知部２１による警報の報知と、第二報知部２２による警報器１の状態の報知とを識別可能に構成してもよい。 When an alarm lamp is employed as the alarm notification unit 21, the alarm lamp and the operation check lamp as the second notification unit 22 are also used, and light emission patterns such as lighting, blinking, and extinction, and light emission such as green and red, respectively. By changing the combination of colors, the alarm notification by the alarm notification unit 21 and the notification of the state of the alarm device 1 by the second notification unit 22 may be distinguishable.

上述した実施形態では、第二報知部２２が動作確認ランプである場合について説明したが、第二報知部２２は、動作確認ランプに替えて、又は加えて、動作確認ブザーや動作確認スピーカであってもよく、動作確認ブザーの鳴動や、動作確認スピーカからの合成音声、又は、電子音等による音、又はそれらの組み合わせによって、警報器１の正常、ＬＰガスの漏洩等の異常検知、故障等の状態を報知する構成であってもよい。 In the embodiment described above, the case where the second notification unit 22 is an operation check lamp has been described. However, the second notification unit 22 is an operation check buzzer or an operation check speaker in place of or in addition to the operation check lamp. It is possible to detect normality of the alarm device 1, abnormality such as leakage of LP gas, failure, etc. by sounding the operation confirmation buzzer, synthesized sound from the operation confirmation speaker, sound by electronic sound, or a combination thereof. The structure which alert | reports the state of (2) may be sufficient.
