Description

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

  Conventionally, residential alarm devices (hereinafter referred to as “residential alarms”) that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. There is also an increasing tendency to monitor the anomalies such as fires in each room by installing a vessel.

  In this way, when a plurality of house alarms are installed in a dwelling unit, if a person is in a room different from the room where the abnormality has occurred, a warning sound may not be heard and a disaster such as a fire may spread. For this reason, when a fire alarm is detected and alarmed by a certain resident alarm, communication is made between the resident alarms, so that a linked alarm can be made to send a signal to other resident alarms by wire or wirelessly to make an alarm at the same time. .

In addition, a lighting device is installed in the house guard to turn it on as an emergency light in the event of a power failure (Patent Literature), or when a fire is detected, the light emitting display is activated to irradiate the floor and light is turned off. There has been proposed (Patent Document 2) that facilitates evacuation when a fire occurs at night.

JP 2005-293308 A JP 2006-39818 A

  By the way, in such a conventional alarm device, in many cases, it is driven by a battery. After a fire is detected and alarmed, a lighting device is driven to illuminate a monitoring area, and then an alarm stop operation is performed. If it is performed, the driving of the lighting device is also stopped in order to avoid unnecessary battery consumption.

  However, there is a case where an alarm stop operation is performed to avoid confusion even in the case of evacuation due to an actual fire. In such a case, if the driving of the lighting device is also stopped by the alarm stop operation, at night, etc. If the warning is stopped, the lights will turn off and you may lose visibility and interfere with the evacuation behavior.

An object of the present invention is to provide an alarm device that prevents loss of function due to unnecessary battery consumption without impairing securing an evacuation route by driving a lighting device.

The present invention is an alarm device that detects an abnormality in a monitoring area by a sensor unit and alarms by a notification unit.
A lighting device that illuminates part or all of the monitoring area;
A lighting control unit that drives the lighting device based on the abnormality detection by the sensor unit or other alarm device,
The illumination control unit holds the driving state for at least a predetermined period when an alarm stop operation is determined during driving of the lighting device.

  Here, the illumination control unit provides a predetermined delay time after the abnormality detection by the sensor unit or other alarm device until the illumination device is driven.

The lighting control unit does not drive the lighting device when an alarm stop operation is determined during the delay time.

  According to the present invention, even if the alarm stop operation is determined during the illumination drive, the drive state is maintained for at least a predetermined period. Therefore, even if the alarm stop operation is performed during the evacuation, there is a risk that the illumination will immediately disappear and the view may be lost. There is no evacuation, and an evacuation route can be secured appropriately to evacuate safely.

In addition, a delay time is provided at the start of driving of the lighting device, and if the alarm stop operation is determined within this time, the lighting device is not driven, and there is a possibility of unnecessary battery consumption due to false or non-fire reports. Can be reduced.

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

  In FIG. 1, the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. In the center of the cover 12, a smoke detecting section 16 having a smoke inlet is opened around it 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 detecting section 16 provided in the cover 12, and a buzzer or a speaker is incorporated behind this so that an alarm sound or a voice message can be output. An LED 22 that operates as an alarm display unit is disposed on the cover 12. An alarm stop switch 20 is provided below the smoke detector 16. The alarm stop switch 20 also functions as an inspection switch for instructing a test of the function of the alarm device.

  An illumination device 24 is arranged inside the alarm stop switch 20 as shown by a dotted line. When the illumination device 24 is turned on, the switch cover of the alarm stop switch 20 is formed of a translucent resin. A part of the monitoring area in which the house guard is installed is illuminated by irradiating illumination light to the outside through the 20 switch cover portions. For example, a white LED is used as the illuminating device 24, and the monitoring area can be illuminated by irradiating with sufficient illumination light with low power consumption.

  A mounting hook 15 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 of the room to be installed, and the mounting hook 15 is hooked on the screw to attach the housing alarm 10 to the wall surface. Can be installed. Although the wall-mounted type is used in the present embodiment, there is also a residence guard that is attached to the ceiling.

  The installation position of the lighting device 24 is not limited to the inside of the alarm stop switch 20, but can be arranged at any position of the cover 12, and the illumination direction may be fixed to face the floor surface, for example. You may arrange | position freely so that it may face arbitrary illumination directions.

  Moreover, in the residential alarm 10 of FIG. 1, although the residential alarm which detects the smoke by the fire provided with the smoke detection part 16 is taken as an example, the thermistor which detects the heat by a fire besides this is equipped. Also included in the scope of the present invention are residential alarms, residential alarms that detect gas leaks other than fire, and residential alarms that detect both fire and gas leaks.

  FIG. 2 is an explanatory view showing an installation state of a house alarm device according to the present invention for a house. In FIG. 2, residence guards 10-1 to 10-4 are installed in the kitchen, living room, main bedroom, and children's room provided in the house 25, and also in a garage 27 built outdoors. The residence guard 10-5 is installed.

  Each of the home alarm devices 10-1 to 10-5 has a function of transmitting / receiving event signals wirelessly and a function of outputting and displaying an alarm, and the five home alarm devices 10-1 to 10-5 are provided. One alarm group is formed to monitor the fire of the entire house. Note that the technique of the present invention can be applied to a house alarm system that is wired instead of wireless, or a house alarm system that mixes wireless communication and wired communication.

  If a fire has occurred in the child room of the house 25, the residence guard 10-4 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm. When the resident alarm 10-4 is triggered, the resident guard 10-4 functions as an interlocking source, and fires are issued to the other resident alarms 10-1 to 10-3 and 10-5 that are the interlocking destinations. An event signal indicating is transmitted by radio. In the other home alarm devices 10-1 to 10-3, 10-5, when receiving an event signal indicating a fire alarm from the home alarm device 10-4 as the interlock source, the alarm operation as the interlock destination is performed. Do.

  Here, as the alarm sound of the home alarm device 10-4 that is the link source, for example, “Please confirm that the Woo fire alarm has been activated” is continuously output by voice message. On the other hand, in the interlocked residence alarm devices 10-1 to 10-3 and 10-5, a voice message such as “Please confirm that another fire alarm has been activated” is output continuously. Regardless of the voice message, it may be possible to use a different buzzer sound or a display that can visually identify the interlock source and the interlock destination together with the buzzer sound.

  Thus, the residential alarm devices 10-1 to 10-5 that have determined fire detection and output an alarm sound further drive the lighting device 24 to illuminate the monitoring area.

  When the alarm stop switch 20 provided in the residence guard shown in FIG. 1 is operated in a state where the residence guards 10-1 to 10-5 are emitting an alarm sound, each of the residence guards performs an alarm sound stop operation. Then, a predetermined alarm sound stop process is performed. The illuminating device 24 being driven does not stop immediately in response to the alarm sound stop operation, but stops after the driving state is maintained for a predetermined time.

  FIG. 3 is a block diagram showing the construction of a home alarm device for constructing an alarm system according to the present invention together with other home alarm devices. The alarm system of FIG. 3 shows the internal processing block configuration in detail for the five home alarm devices 10-1 to 10-5 shown in FIG.

  The home guard 10-1 includes a CPU 28, and the CPU 28 includes a wireless circuit unit 30 including an antenna 31, a memory 32, a sensor unit 34, a notification unit 36, a lighting device 24, an operation unit 38, and a battery power source 40. ing.

  The wireless circuit unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be transmitted and received wirelessly between the other mortgages 10-2 to 10-5. As the radio circuit unit 30, in Japan, for example, STD-30 (standard standard of radio equipment of a low power security system radio station) or STD known as a standard of a specific low power radio station of 400 MHz band or STD. -It has a configuration compliant with T67 (standard for specific low-power radio station telemeter, telecontrol and data transmission radio equipment).

  Of course, the radio circuit unit 30 has contents conforming to the standard of the assigned radio station in the area in places other than Japan.

  The memory 32 stores a transmission source code 50 that is an ID (identifier) for identifying a house alarm, and a group code 52 for configuring a group that performs a linked alarm with a plurality of house alarms as shown in FIG. Yes. As the transmission source code 50, the number of home guards provided in the country is predicted, and for example, a 26-bit code code is used so as not to be duplicated as the same code.

  The group code 52 is a code that is set in common to a plurality of residential alarms constituting the group, and the group code included in the event signal from the other residential alarm received by the wireless circuit unit 30 is registered in the memory 46. This event signal is received as a valid signal and processed when the group code 52 matches.

  The identification of the alarm group may use a transmission source code that is an ID for identifying a residential alarm in addition to the group code. In other words, the source codes of other house alarm devices belonging to the same group are registered in advance in the plurality of house alarm devices constituting the group, and the source codes included in the event signals received from the other house alarm devices are Compared with the registered transmission source code, if they match, the signal is processed as a signal from a resident alarm device belonging to the same group.

  In this embodiment, the memory 32 is used. However, for example, a dip switch may be provided instead of the memory 46, and the transmission source code 50 and the group code 52 may be set by the dip switch. When the code length (number of bits) of the transmission source code 50 or the group code 52 is small, there is an advantage in usability in using a dip switch.

  In the present embodiment, the sensor unit 34 is provided with the smoke detector unit 16. In addition to the smoke detector 16, the sensor unit 34 may be provided with a thermistor, for example, for detecting the temperature due to a fire. Further, in the case of a residence warning device for gas leak monitoring, a gas leak sensor is provided.

  The notification unit 36 is provided with a speaker 58 and an LED 22. The speaker 58 outputs a voice message or an alarm sound from a voice synthesis circuit unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting.

  The illumination device 24 uses a white LED, and illuminates a part or all of the monitoring area by lighting driving. The illumination device 24 has an illuminance of an appropriate illuminance within a range that does not impair the life of the battery power supply 40, and enables illumination equivalent to, for example, a flashlight. Note that the lighting device may be driven intermittently as long as the substantial purpose of illumination can be achieved.

  The operation unit 38 is provided with an alarm stop switch 20. When the alarm stop switch 20 is operated, the alarm sound flowing from the residential alarm 10-1 can be stopped. In the present embodiment, the alarm stop switch 20 is also used as an inspection switch for instructing a test of the function of the alarm device.

  The alarm stop switch 20 is effective when an alarm sound is output from the notification unit 36 through the speaker 58. On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal monitoring state in which no alarm sound is output. When the inspection switch is pressed, a notification voice message or the like is output from the notification unit 36. The registration switch 54 sets various modes necessary for controlling the lighting device 24.

  The battery power source 40 uses, for example, an alkaline dry battery having a predetermined number of cells, and the battery capacity is driven by driving down the lighting device 24 by reducing the power consumption of the entire circuit unit including the wireless circuit unit 30 in the residence guard 10-1. If not, a battery life of about 10 years is assumed, and if the lighting device 24 is assumed to be driven, a battery life of about 5 years is guaranteed.

  The CPU 28 is provided with an abnormality monitoring unit 60 and an illumination control unit 62 as functions realized by executing the program. When the smoke monitoring unit 16 provided in the fire sensor unit 34 detects a fire, the anomaly monitoring unit 60 confirms the alarm sound indicating the interlock source from the speaker 58 of the notification unit 36, for example, “Woo Woo fire alarm has been activated. Please repeatedly output "and an event signal indicating a fire alarm is transmitted from the antenna 31 to the other residential alarm devices 10-2 to 10-5 by the transmission circuit 42 of the wireless circuit unit 30.

  Moreover, when the abnormality monitoring unit 60 receives an event signal indicating a fire alarm from any of the other home alarm devices 10-2 to 10-5 by the reception circuit 44 of the wireless circuit unit 30, the abnormality monitoring unit 60 From 58, an audible sound indicating the link destination, for example, “Woo-woo, check if another fire alarm has been activated” is output continuously.

  Here, when the abnormality monitoring unit 60 detects a fire alarm and outputs an interlocking source alarm sound, the LED 22 of the notification unit 36 is blinked, for example. On the other hand, when the abnormality monitoring unit 60 emits an interlocking destination alarm sound, the LED 22 of the notification unit 36 is blinked. Thereby, the display of the LED 22 in the interlocking source alarm and the interlocking destination alarm can be distinguished. Of course, the blinking or flashing display of the same LED 22 may be used for both the interlocking source alarm and the interlocking destination alarm.

  Further, when the abnormality monitoring unit 60 detects the operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the alarm sound indicating the interlock source, the abnormality monitor unit 60 outputs an alarm sound indicating the interlock destination output from the speaker 58. While stopping, the alarm stop event signal is transmitted from the transmission circuit 42 of the radio circuit unit 30 to the other residential alarm devices 10-2 to 10-5, and the interlock destinations in the other residential alarm devices 10-2 to 10-5 Stop the alarm sound.

  At this time, in order to clarify the location of the fire, only the interlocking home alarm device 10-4 (the home alarm device whose fire sensor unit has detected a fire) may continue to output the alarm. . And when alarm stop operation is performed by the interlocking home police 10-4, the alarm of all the residential policers including the interlocking destination is stopped.

  The illumination control unit 62 drives the illumination device 24 based on the following control content.

  (1) The lighting device 24 is driven when a pre-driving condition by the sensor unit 24 or the other alarm devices 10-2 to 10-5 is established.

  (2) When a valid alarm stop operation is determined while the lighting device 24 is being driven, the driving state is maintained for at least a predetermined period.

  (3) After the pre-driving condition by the sensor unit 24 or the other alarm devices 10-2 to 10-5 is established, the lighting device 24 is driven after a predetermined delay time has elapsed.

  Among these, the basic one is the illumination control (1) and (2), and the illumination control is performed by selecting (3) and combining it.

  Further, the illumination device 24 can be temporarily driven when a test operation for operating the alarm stop switch 20 in the normal monitoring normal state is determined.

  The circuit unit provided in such a home alarm device 10-1 is the same for the other home alarm devices 10-2 to 10-5, and the transmission source code 50 stored in the memory 32 is unique to each home alarm device. It is a sign.

  FIG. 4 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 4, the event signal 48 includes a transmission source code 50, a group code 52, and an event code 54.

  The transmission source code 50 is a 26-bit code, for example. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the five residential alarm devices 10-1 to 10-5 in FIG.

  In addition, as the group code 52, in addition to setting the same group code to the same group of house alarms, a reference code common to the house alarms constituting a predetermined group, and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code.

  Moreover, when registering a transmission origin code | symbol in each residence guard and performing group determination, the group code | symbol 52 does not need to be provided.

  The event code 54 is a code representing the event contents such as fire and gas leak. In this embodiment, a 2-bit code is used. For example, “001” is a fire, “010” is a gas leak, “011” indicates a failure and the rest is reserved. The number of bits of the event code 54 can be further increased to 3 bits and 4 bits when the types of events increase, thereby representing a plurality of types of event contents.

FIG. 5 is a time chart showing the first embodiment of the fire monitoring process according to the embodiment of FIG.
In this embodiment, as described in the above (1) and (2), when the lighting device 24 is driven when a fire detection is determined, and an effective alarm stop operation is determined while the lighting device 24 is being driven, It is characterized by holding for a predetermined period.

  In FIG. 5, the fire monitoring process performs an initialization process in step S1. This initialization process includes setting of a group code for forming a group with, for example, five dwelling devices 10-1 to 10-5 installed in the same dwelling unit.

  Subsequently, the fire alarm is monitored in step S2, and when the fire alarm by the sensor unit 34 or the fire alarm signal by the fire event signal from another house alarm device is determined, the process proceeds to step S3 and the fire alarm is output.

  The fire alarm is a fire alarm indicating the interlock source in the case of own fire alarm, and the fire alarm indicating the interlock destination is issued in the case of fire alarm of other dwelling devices. In addition, if it is a self-fire notification, an event signal indicating the occurrence of a fire is wirelessly transmitted to the other home alarm devices.

  Subsequently, in step S4, the illumination device 24 is driven to illuminate a part or all of the monitoring area. During lighting by driving the lighting device 24, it is determined whether or not there is an alarm stop operation by the alarm stop switch 20 in step S6. When the alarm stop operation is determined, the fire alarm is stopped in step S6. At this time, if it is its own fire alarm, an event signal indicating the alarm stop is transmitted to the other residential alarm.

  Subsequently, after maintaining the driving state of the lighting device 24 for a predetermined time in step S7, the driving of the lighting device 24 is stopped in step S8, and the process returns to step S2.

  According to such illumination control of the first embodiment, even if an alarm stop operation is determined during illumination driving, the driving state is maintained for a predetermined period, so even if there is an alarm stop operation during evacuation, There is no danger of losing visibility as soon as the lights are turned off, and it is possible to evacuate safely by securing an appropriate evacuation route.

FIG. 6 is a time chart showing a second embodiment of the fire monitoring process according to the embodiment of FIG.
In this embodiment, as described in (3), after the pre-driving condition by the sensor unit 24 or other alarm devices 10-2 to 10-5 is satisfied, the lighting device 24 is driven after a predetermined delay time has elapsed. It is characterized by that.

  The process of FIG. 6 is obtained by adding the processes of steps S14 to S17 to the first embodiment of FIG. 5. Steps S11 to S13 of FIG. 6 are the same as steps S1 to S3 of FIG. Steps S18 to S22 of 6 are the same as steps S4 to S8 of FIG.

  That is, in the process of FIG. 6, after fire detection is determined in step S12 and a fire alarm is output in step S13, the process waits for a predetermined delay time to elapse in step S14, and proceeds to step S18 after the delay time elapses. The illuminating device 24 is driven. If an alarm stop operation is determined in step S16 during the delay time, the process proceeds to step S17 without driving the illumination device 24, and the alarm is stopped.

  According to such illumination control of the second embodiment, a delay time is provided at the start of driving of the lighting device, and when the alarm stop operation is determined within this time, the lighting device is not driven. This can reduce the possibility of unnecessary battery consumption due to false or non-fire reports.

  In addition, although the above embodiment was taken as an example of a residential alarm intended for fire detection, other than this, a residential alarm that detects other appropriate abnormalities such as a gas leak alarm or a security alarm The alarm stop process of this embodiment can be applied as it is for the alarm device. Moreover, it can be applied not only to residential use but also to various types of alarm devices such as buildings and offices.

  For example, in the case of a fire alarm that detects a fire as an abnormality, there may be cases where evacuation lighting is not necessary due to the presence of a flame at the location of the fire. In this case, the alarm detection source alarm device does not need to be lit. Therefore, only the alarm device (interlocking destination alarm device) that has determined abnormality detection by other alarm devices, excluding the alarm device in which the abnormality is detected, may be set as the illumination lighting target candidate.

  In the above embodiment, the alarm unit is provided with the sensor unit and the alarm output processing unit as an example. However, as another embodiment, the alarm unit has a separate sensor unit and alarm output processing unit. There may be.

  Moreover, although said embodiment took the example of the wireless residence guard, it can be applied as it is even if it is a wired residence guard about alarm stop processing.

  In the above embodiment, a plurality of residential alarms are installed and a fire alarm information is sent and received by wire or wireless to each other and linked alarms are taken as an example, but they are not linked to other residential alarms. The present invention can be applied as it is to a stand-alone house alarm that operates alone.

The present invention is not limited to the above embodiment, includes appropriate modifications without impairing the object and advantages thereof, and is not limited by the numerical values shown in the above embodiment.
