Description

The present invention relates to an alarm device for detecting and alarming an abnormality such as a fire or a gas leak.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. Of these, residential disaster alarms are referred to as residential alarms.

  In such a house alarm, a sensor unit and an alarm unit are integrated in the house alarm, and when a fire is detected by the sensor unit, a fire alarm is output from the alarm unit by voice message, etc. Because it is possible to perform fire monitoring and alarm with a single residence guard without requiring any receiving equipment, it is easy to install and inexpensive, and it is widely used with the mandatory installation in ordinary houses.

  On the other hand, by communicating between multiple home alarms, if a fire alarm is given by any home alarm, another type of home alarm system is also proposed, in which other home alarms also give an alarm. Has been.

  In such a home alarm system, when a fire is detected by the home alarm, the home alarm device that detected the fire is, for example, “Please check that the Woo Woo Fire Alarm has been activated”. A voice message is output. When an alarm is issued by the house alarm, the alarm is stopped by operating an alarm stop switch provided in the house alarm.

On the other hand, when the alarm stop switch is operated in the normal monitoring state, the inspection is executed and the inspection result is output by a voice message.

An output section;
Is provided.

  Here, the alarm history output unit causes the notification unit to output information indicating the second history of the abnormality alarm output in the first operation when the long press operation of the operation unit is detected as the push operation.

    The alarm history output unit outputs information indicating the fact of occurrence of abnormality as information of the first history, and outputs the fact of occurrence of abnormality and detailed information of occurrence of abnormality from the notification unit as information of the second history.

The alarm history output unit notifies the history of the abnormal alarm by the alarm sound of the notification unit, the alarm display, or the combination of the alarm sound and the alarm display. The alarm history notification is repeated or continued for at least a predetermined period.

  According to the present invention, when an alarm such as a fire is detected and an alarm is issued, an alarm history is stored, and even after the alarm is stopped, the operation unit is operated within a predetermined time from the alarm stop. When the operation is performed, the alarm history saved at the time of the alarm is read out, and at least the alarm alarm history immediately before (at the latest alarm) is notified. Appropriate responses such as confirmation of no trouble ringing and complaints without alarming facts can be made appropriately.

  In addition, the alarm stop and history output are performed by operating the same switch provided in the operation unit, so that the user can operate as a single multifunction switch without being aware of the switch pressing operation. It is possible to reliably notify the alarm history even to general users who do not.

  In addition to the alarm stop and alarm history output, the multi-function switch on the operation unit can also be used as an operation switch for checking and / or confirming battery exhaustion when the battery voltage drops, and which function is performed depending on the situation at the time of operation reception Since it is determined on the side of the alarm device, the user can perform an appropriate operation according to the state of the alarm device without being aware of the push operation of the switch.

Further, since a warning history is not output even if a switch operation is performed after a predetermined time has elapsed since the alarm stop, user confusion due to a history output after a long time has passed since the alarm stop can be avoided.

Explanatory drawing which showed the external appearance of the house alarm device by this invention The block diagram which showed embodiment of the residence guard shown in FIG. Explanatory diagram showing an example of alarm history The flowchart which showed the housing alarm processing operation in embodiment of FIG. Explanatory diagram showing another example of alarm history The flowchart which showed the house alarm processing operation in other embodiment using the log | history information of FIG.

  FIG. 1 is an explanatory view showing the appearance of a house alarm device according to the present invention. FIG. 1 (A) shows a front view and FIG. 1 (B) shows a side view.

  In FIG. 1, the housing of the residential alarm 10 according to this embodiment includes a cover 12 and a main body 14. A plurality of smoke inlets are opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12, so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  An acoustic hole 18 is provided on the lower left side of the smoke detector 16 provided in the cover 12, and a buzzer and a speaker are built in behind this so that an alarm sound and a voice message can be output. A multifunction switch 20 is provided below the smoke detector 16.

  The multi-function switch 20 functions as an alarm stop switch, an inspection switch, a battery exhaustion notification (voltage drop confirmation) switch, and an alarm history output switch in accordance with the operating state of the home alarm device 10 when the switch is operated.

  For example, when the multifunction switch 20 is operated at the time of a fire alarm of the residential alarm 10, it functions as an alarm stop switch that stops the alarm. When the multifunction switch 20 is operated in the normal state of the home alarm device 10, it functions as an inspection switch that executes a predetermined inspection operation and outputs an inspection result by a voice message.

  Further, for example, when the multifunction switch 20 is operated in a state in which a battery voltage drop is detected by the home alarm device 10, it functions as a battery exhaustion notice confirmation switch that outputs a battery advance notice and a message prompting battery replacement. Further, when the multifunction switch 20 is operated within a predetermined time after stopping the alarm of the residential alarm 10, it functions as an alarm history output switch for outputting the alarm history stored at the time of alarm by a voice message.

  For this reason, the multi-function switch 20 functions simply as an alarm stop switch, an inspection switch, a battery exhaustion notification switch, or an alarm history output switch, depending on the operating state of the home alarm device 10 at that time, The user does not need to be aware of the push-and-hold operation such as the long switch operation, and can easily perform the necessary operation.

  The multifunction switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) disposed inside the switch cover. In the vicinity of the tact switch inside the switch cover, an LED 22 for displaying an alarm is arranged as indicated by a dotted line. When the LED 22 is turned on, blinks, or blinks, the LED 22 is transmitted through the switch cover portion of the multifunction switch 20. The operating state of the system is made known from the outside.

  A mounting hook 15 having an insertion hole in the substantially central portion is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into the wall surface of the room to be installed, and the screw is passed through the insertion hole of the mounting hook 15. The residential alarm 10 can be fixedly installed on the wall surface or the like.

  In the residential alarm 10 of FIG. 1, a smoke detector 16 is provided as an example, and a residential alarm that detects smoke due to fire is taken as an example. However, the temperature of a thermistor or the like that detects heat due to fire is also taken as an example. House alarms with detection elements, house alarms that detect other physical phenomena associated with fires, alarms that detect gas leaks in addition to fires, various alarms that detect intruders, earthquakes, and other abnormalities, etc. Alarm devices formed by combining these are also included in the subject of the present invention.

  FIG. 2 is a block diagram showing an embodiment of the residential alarm shown in FIG. In FIG. 2, the home alarm device 10 includes a processor 24 known as a one-chip CPU. A circuit unit 36 and a battery power source 38 are provided.

  The sensor unit 26 includes a smoke detector 16 that detects smoke and outputs a signal. As described above, the sensor unit 26 may be provided with a temperature detecting element such as a thermistor for detecting the temperature due to a fire, and various elements for detecting other physical phenomenon changes accompanying the fire, instead of the smoke detecting unit 16.

  The notification unit 28 is provided with a speaker 44 that outputs an alarm sound and an LED 22 that displays an alarm. The speaker 44 outputs a voice message and an alarm sound from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. A buzzer or the like may be used instead of the speaker 44. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  The operation unit 30 is provided with a multi-function switch 20. The multi-function switch 20 functions as an alarm stop switch, an inspection switch, a battery exhaustion notification switch, or an alarm history output switch, depending on the operation state of the home alarm device 10 at that time.

  The memory 34 stores an alarm history 40 and a battery voltage drop flag 42. For example, as shown in FIG. 3, the alarm history 40 is stored as alarm history records 40-1 to 40-n, and combinations of fire detections 1 to n and detection times 1 to n specified by time acquisition means (not shown), respectively. In this example, the alarm history record 40-1 is the latest information.

  Which of the alarm history records 40-1 to 40-n is the latest record may be determined based on the detection times 1 to n as described above, or may be determined based on, for example, the storage order of the records. Alternatively, the storage area (address) may be stored in association with the old and new, and the determination may be made based on the storage area. In this case, it is not necessary to add the detection times 1 to n to the alarm history records 40-1 to 40-n. If it does in this way, time acquisition means, such as a clock for specifying detection time, from the composition of residence guard 10 can be omitted.

  Note that the maximum value of n is a predetermined natural number. That is, it is not prevented that the history record stored in the memory 34 is a maximum of one.

  The battery voltage drop flag 42 is set when the processor 24 detects a battery voltage drop due to exhaustion of the battery power supply 38. Based on the set state of the battery voltage drop flag 42, this flag set is set when the multi-function switch 20 is operated. If there is, a battery exhaustion warning message prompting battery exhaustion and battery replacement is output.

  When a fire is detected, the transfer circuit unit 36 outputs a transfer signal to other devices when the fire is detected by a signal line connection to perform an interlocking operation. The transfer signal is, for example, a no-voltage contact signal.

  The battery power supply 38 uses, for example, a lithium battery or an alkaline dry battery having a predetermined number of cells, and as a battery capacity, for example, guarantees a battery life of 10 years by reducing the power consumption of the entire circuit unit in the residential alarm 10. Yes.

  As functions realized by execution of the program in the processor 24, functions of an alarm processing unit 46, an alarm stop unit 48, an inspection processing unit 50, a battery voltage drop monitoring unit 52, an alarm history holding control unit 54, and an alarm history output unit 56 are provided. Is provided.

  The alarm processing unit 46 outputs an alarm sound indicating a fire from the speaker 44 when the fire is detected from the smoke detection signal from the sensor unit 26 and drives the LED 22 to display an alarm.

  More specifically, the alarm processing unit 46 compares the smoke detection signal of the smoke detector 16 provided in the sensor unit 26 with a predetermined threshold, and when the fire is detected by exceeding the threshold, The speaker 44 repeatedly outputs an alarm sound, for example, “Woo Woo is a fire”, and turns on the LED 22 to display an alarm.

  When the alarm stop unit 48 detects the operation of the multi-function switch 20 during the output of the fire alarm, the alarm stop unit 48 stops the output of the fire alarm by the voice message from the speaker 44 and the alarm display of the LED 22. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time.

  The inspection processing unit 50 performs a predetermined internal inspection when the operation of the multifunction switch 20 provided in the operation unit 30 is detected in the normal monitoring state, and outputs the inspection result from the notification unit 28. If the inspection result is output normally, an inspection message including an alarm message such as “normal” is output, and if a failure is detected, an inspection message such as “pick failure” is output. The contents to be inspected in the inspection process include presence / absence of smoke detector 16 (sensor) failure, presence / absence of circuit failure, presence / absence of sensitivity abnormality, presence / absence of other failures, and the like.

  For example, for the detection of a sensor failure, the inspection processing unit 50 reads the smoke detection signal output from the smoke detector 16 of the sensor unit 26 at a predetermined measurement time interval T1, for example, T1 = 1 second by A / D conversion, and stores the memory. 34, for example, every predetermined time interval T2 = 10 minutes, an average value of 10 minutes of detection data held in the buffer area of the memory 34 is obtained, and this average value is a predetermined reference level. When the value falls below (referred to as the zero point level), it is determined that the smoke detector 16 has failed because the output is stopped, and a check result message such as “pick failure” is output when the multi-function switch 20 is operated.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point level in this way may be that a failure such as disconnection of the light receiving element provided in the smoke detector 16 or stop of the light receiving amplifier has occurred. Is expensive. Even when a temperature detection element such as a thermistor is provided in the sensor unit 16, a sensor failure or failure can be detected in the same manner.

  When the multifunction switch 20 is operated while a failure (including a failure) is detected, a failure alarm stop process may be performed after performing a predetermined internal inspection and informing the result. In this way, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be more clearly aware of the failure state. If the failure state has been resolved at this time, for example, a message such as “The failure has been resolved” may be output, and the processing may proceed to failure alarm stop processing.

  The battery voltage drop monitoring unit 52 reads the power supply voltage of the battery power supply 40 by A / D conversion via the battery voltage detection unit 32 at a predetermined measurement time interval T3, for example, T3 = 4 time intervals, and sets the predetermined threshold voltage. In comparison, it is determined that the battery has a low battery failure (battery voltage drop abnormality) when the voltage is lower than the threshold voltage, and the low battery failure is determined when the determination of the low battery failure continues for a predetermined number of times. The voltage drop flag 42 is set.

  The alarm by the battery voltage drop monitoring unit 52 outputs, for example, “Battery out of battery” three times when a low battery failure is determined, and blinks the LED 22 in synchronization with the alarm sound. After that, based on the set state of the battery voltage drop flag 42, for example, an alarm sound such as “Battery is dead” is output three times as a regular ringing. When the multi-function switch 20 is operated, “battery exhausted” is output once, and the LED 22 blinks at the same time. At this time, the multi-function switch 20 functions as a battery deadline notice switch.

  When the alarm processing unit 46 detects a fire, the alarm history holding control unit 54 saves, for example, a history record including a combination of the fire detection and the detection time shown in FIG. When the detected time is stored as the history information 40, a calendar IC for generating time information is provided as time acquisition means.

  The alarm history output unit 56 detects history information 40 stored in the memory 34 by the alarm history holding unit 54 when the first operation by the multifunction switch 20 is detected at least within a predetermined period after the alarm is stopped by the operation of the multifunction switch 20. The history record 40-1 indicating the history of at least the latest abnormality alarm is read out, and information indicating the fact that the fire alarm is performed is output from the speaker 44 of the notification unit 28 based on the history information.

  Not only the first operation but also the operation of the multi-function switch 20 up to a predetermined number of times within a predetermined time may be accepted as this alarm history output operation. May be accepted as an alarm history output operation, or may be accepted as an alarm history output operation for the first time or up to a predetermined number of times regardless of the period.

  Even when the alarm is not stopped by operating the multi-function switch 20, the fire level in the monitoring area is eliminated and the smoke concentration is reduced. As a result, the signal level from the sensor unit 26 is also reduced and a fire is detected by the alarm processing unit. When it is no longer possible, the alarm stop unit 48 stops the fire alarm (automatic recovery). As described above, even when the alarm is stopped by the fire recovery, the history output reception and the process by the operation of the multi-function switch 20 are the same as the processes after the alarm stop by the operation of the multi-function switch 20 is performed. It can be.

  FIG. 4 is a flowchart illustrating the processing operation in the residential alarm 10 of FIG. In FIG. 4, when the power supply by the battery power source 38 of the mortgage alarm device 10 is started, initialization and self-diagnosis are executed in step S1, and if there is no abnormality, the process proceeds to step S2 to determine the presence or absence of fire detection, When the fire detection is determined, the process proceeds to step S3, where a fire alarm is output by a voice message from the speaker 44 and an alarm display by turning on the LED 22, and then the fire detection shown in FIG. And a history record consisting of a set of detection times.

  Subsequently, in step S5, it is determined whether or not the multifunction switch 20 is operated. When the switch operation is determined, the alarm sound from the speaker 44 is stopped in step S6, and the alarm display by turning on the LED 22 is turned off. Stop the alarm. The LED 22 may be turned off after a predetermined time has elapsed. At this time, the multi-function switch 20 functions as an alarm stop switch.

  Even if the multi-function switch 20 is not operated, the smoke detection signal from the sensor unit 26 decreases, the fire condition is eliminated, and the fire alarm is stopped when the fire is restored.

  Subsequently, in step S7, it is determined whether or not a predetermined time has elapsed from the stop of the fire alarm. If the operation of the multi-function switch 20 is determined in step S8 before the progress, the process proceeds to step S9 and the alarm history 40 in the memory 34 is determined. The latest history record 40-1 is read out, and a voice message indicating the fact that a fire alarm such as “pick alarm operation is being performed” is output from the speaker 44. At this time, the multifunction switch 20 functions as an alarm history output switch.

  Here, an example is given in which only the latest history record is output by the first operation of the multi-function switch 20 after a predetermined time has elapsed after the fire alarm is stopped in step S6. Not only 40-1, but also a predetermined number from the latest one, for example, two records 40-1 and 40-2 may be output, or all stored records 40-1 to 40-n. May be output in order. Further, before the predetermined time elapses, 40-1 and 40-2 may be sequentially output every time the multifunction switch 20 is operated.

  If there is no operation of the multi-function switch 20 until the predetermined time elapses in step S7, the alarm history is not output and the process proceeds to step S10.

  Here, step S7 may be deleted, and the history record 40-1 may be output by the first operation of the multifunction switch 20 after step S6. Similarly, in the first operation, a predetermined number may be output from the latest one, or all stored records 40-1 to 40-n may be output in order. Further, the latest 40-1 may be output by the first operation, and the next new 40-2 may be output by the second operation.

  In step S10, it is determined whether or not there is a battery voltage drop detection (low battery failure). If battery voltage drop detection is determined, the process proceeds to step S11, and a warning for running out of the battery is performed by a voice message from the speaker 44 and blinking of the LED 22. Then, the process proceeds to step S12, and the battery voltage drop flag 42 of the memory 34 is set. During the setting of the battery voltage drop flag 42, for example, a warning sound such as “Battery is dead” is output three times as a regular ringing every minute, for example.

  Subsequently, the process proceeds to step S13, where it is determined whether or not the multi-function switch 20 is operated in a normal state where no fire alarm, alarm stop, or inspection is performed. If switch operation is determined, the process proceeds to step S14, and smoke detection An inspection process is performed for the presence / absence of a failure in the unit 16, the presence / absence of a circuit failure, the presence / absence of a sensitivity abnormality, the presence / absence of other failures, and the like.

  Subsequently, in step S15, it is determined whether or not the battery voltage drop flag 42 is set in the memory 34. If reset is determined, the process proceeds to step S16, and the check result, that is, whether it is normal or faulty, is output by a voice message from the speaker 44. At this time, the multi-function switch 20 functions as an inspection switch.

  On the other hand, if it is determined in step S15 that the battery voltage drop flag 42 has been set, the process proceeds to step S17, and, similarly to step S11, a warning for battery exhaustion is given by an alarm message from the speaker 44 and blinking of the LED 22. At this time, the multi-function switch 20 functions as a battery deadline notice switch.

  If the multifunction switch 20 is operated after the battery voltage drop flag is set in step S12, the inspection process may not be performed, and the process may immediately proceed to step S17 (step S10, Yes → S11 → S12 → switch). With operation → S17). In this case, on the other hand, the process proceeds from step S10, No to steps S13, S14, and step S15 is omitted, and the process proceeds to step S16 (step S10, No → S13, Yes → S14 → S16).

  The flag 42 set in step S12 may be reset when returning from step S17 to step S2 or when there is no battery voltage drop detection in step S10 from the next time. Note that the flag 42 is reset in the initialization process of step S1 at the first activation and after battery replacement.

  FIG. 5 is an explanatory view showing the history information 40 stored in the memory 34 in another embodiment of the residential alarm according to the present invention. In FIG. 5, history information 40 is stored as history records 40-11 to 40-1n, each comprising fire detection, its detection time, pre-alarm, and its detection time, and history record 40-11 is the latest. . Note that the maximum value of n is a predetermined natural number. That is, it is not prevented that the history record stored in the memory 34 is a maximum of one.

  The pre-alarm is an event when the smoke detection signal from the smoke detector 16 provided in the sensor unit 26 exceeds the pre-alarm threshold set to a level lower than the fire threshold. The situation of the fire can be grasped by whether the temporal change of the smoke detection signal leading up to is sudden or gradual.

  The circuit configuration of the embodiment of the present invention using the history information 40 of FIG. 5 is basically the same as that of FIG. 2, but a pre-alarm detection function is added to the alarm processing unit 46 provided in the processor 24. 2 is different from the embodiment of FIG. 2 in that it has functions of an alarm history holding control unit 54 and an alarm history output unit 56 corresponding to the history information 40 of FIG.

  The alarm history holding control unit 54 stores the pre-alarm detected by the alarm processing unit 46 and the time information thereof, the fire detected subsequently, and the time information thereof in the memory 40 as one history record, for example.

  The alarm history output unit 56 detects the operation of the multi-function switch 20 during the fire alarm, and detects the first operation of the multi-function switch 20 until the predetermined time elapses after the alarm stop unit 48 performs the alarm stop. 34, as history information indicating the fact of a fire alarm based on “fire detection 1” as information indicating the first history in at least the latest history record 40-11 held in 34, for example, “picking alarm operation is performed from the speaker 44. A voice message is output.

  Further, the alarm history output unit 56 detects, for example, a long press operation for 3 seconds as a next press operation of the multi-function switch 20 until a predetermined time elapses after the alarm is stopped. As information indicating the second history that is the detail of 11, for example, content indicating “fire detection 1 and detection time 1” is output from the speaker 44 as a voice message.

  As information indicating the second history, contents indicating “pre-alarm level 1” or “pre-alarm level 1 and detection time 1” may be output as a voice message.

  FIG. 6 is a flowchart exemplifying the house alarm processing of the embodiment for saving and outputting the history information of FIG. 6, steps S21 to S26 are the same as steps S1 to S6 in FIG. 4, and steps S33 to S40 are the same as steps S10 to S17 in FIG. 4, and steps S27 to S32 are specific to this embodiment. History output processing.

  In step S27 of FIG. 6, it is determined whether or not a predetermined time has elapsed since the stop of the fire alarm. If the operation of the multifunction switch 20 is determined in step S28 before the progress, the process proceeds to step S29 and the memory 34 is displayed. The first history indicating the fact of the fire alarm is read out from the latest alarm history record in the alarm history 40, and a voice message such as “the beep alarm operation is being performed” is output from the speaker 44, for example.

  Subsequently, in step S30, it is determined whether or not a predetermined time has elapsed since the stop of the fire alarm (or whether or not a predetermined time has elapsed after the sound output of the first history). When the operation of the multi-function switch 20 or the long press operation is determined, the process proceeds to step S32, and the detection time, pre-alarm, and pre-alarm detection indicating the details of the fire alarm from the latest alarm history record in the alarm history 40 of the memory 34 are detected. The second history such as time is read, and a voice message indicating the details of the fire alarm is output from the speaker 44.

  Of course, the present invention is not limited to such processing, and at least the latest history stored in the memory 34 when the first operation of the multi-function switch 20 is detected before the predetermined time elapses after the alarm stop unit 48 stops the alarm. Based on the information “fire detection 1” indicating the first history in the record 40-11 and the information “detection time 1”, “pre-alarm 1”, and “detection time p1” indicating the second history, for example, “ There may be a voice message such as “There is a pre-alarm for XX hours and XX minutes. Alarm action is being performed for XX hours and XX minutes”.

  Also in the embodiment of FIG. 2, the history records 40-1 to 40-n may include pre-alarm history records. That is, for example, a pre-alarm event can also be handled as a history record of the history information 40 stored in the memory 34 as a history record, similar to a fire alarm (detection) event.

  At this time, the history output by the operation of the multifunction switch 20 after the alarm stop, for example, outputs the latest fire alarm history record, and the pre-alarm history between the latest fire alarm history record and the next new fire alarm history record. Output all messages corresponding to the record. Instead, the number of corresponding pre-alarms may be output.

  In this way, it is useful for estimating and confirming the causes of non-fire reports and misreports due to the installation environment. That is, for example, in the case of the home alarm device 10 having a high pre-alarm frequency, it does not lead to failure or failure, but the internal operation may be unstable, and the installation environment may be dust, dust, steam other than fire smoke. Etc. may easily float, and it is easy to estimate the cause and confirm the cause.

  In the above, fire detection 1 to n is the first history, detection time 1 to nm pre-alarms 1 to n, and detection time p1 to pn is the second history. For example, the first history is fire detection 1 to n and detection. Times 1 to n, the second history as pre-alarms 1 to n, and detection times p1 to pn can be appropriately allocated. Here, at least fire detection 1 to n may be included as the first history.

  Such a second history output may be performed by the user, or may be performed by a specialist in charge of investigating the cause of the fire after the fire is extinguished, and the situation where the fire alarm is given can be easily confirmed later. it can.

  In the above embodiment, the processor 24 has the functions of the alarm processing unit 46, the alarm stop unit 48, the inspection processing unit 50, the battery voltage drop detection unit 52, the alarm history holding control unit 54, and the alarm history output unit 56. Taking the case as an example, the present invention is required to include at least four functions of the alarm processing unit 46, the alarm stop unit 48, the alarm history holding control unit 54, and the alarm history output unit 56.
