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 case of a power failure (Patent Document 1). The thing (patent document 2) which made it easy to evacuate when a fire broke out at night etc. is proposed.

JP 2005-293308 A JP 2006-39818 A

  However, in such a conventional alarm device, when a fire is detected, the lighting device is driven to illuminate the monitoring area regardless of whether there is a person in the monitoring area. Illumination is performed, and in many cases, the alarm device is driven by a battery, and there is a problem that the battery is consumed more than necessary by driving the lighting device.

  In addition, the illuminating device is driven even when it is operated by a false report or non-fire report in the absence, and the battery voltage drops due to the illumination driving for a long time, the battery runs out, and the monitoring alarm function is lost. There is also a problem.

  There are some home alarms that warn you to replace the battery before the battery voltage drops and the battery runs out, but in any case due to unnecessary battery consumption, the battery needs to be replaced more frequently or neglected. However, when it cannot be replaced due to absence or the like as described above, the risk of finally falling into a non-monitoring state due to battery exhaustion increases.

An object of the present invention is to provide an alarm device that can drive a lighting device only when it is necessary to secure an evacuation route at night or the like and prevent loss of function due to unnecessary battery consumption.

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 human sensor for detecting the human body;
A light / dark sensor that detects the illuminance in the monitoring area;
An illumination control unit that drives the illumination device based on abnormality detection by the sensor unit, human body detection by the human sensor, and brightness detection by the brightness sensor;
It is provided with.

  Here, the lighting control unit determines the lighting device when the brightness detection level by the light / dark sensor is equal to or less than a predetermined value when both abnormality detection by the sensor unit or other alarm device and human detection by the human sensor are determined. To drive.

  The lighting control unit, when recognizing the monitoring cancellation operation of the human sensor, determines the abnormality detection by the sensor unit or other alarm device, and when the brightness detection level by the light / dark sensor is equal to or lower than a predetermined value, To drive.

  The illumination control unit provides a delay time from the detection of abnormality by the sensor unit or other alarm device to the lighting of the illumination.

  The lighting control unit holds the driving state for at least a predetermined period after starting the driving of the lighting device.

  The lighting control unit stops driving the lighting device when it determines an alarm stop operation during driving of the lighting device.

  The illumination controller temporarily drives the illumination device when determining the test operation.

  When the lighting control unit recognizes the initially set steady lighting mode, the lighting control unit determines whether the human body detection by the human sensor and the brightness detection level by the brightness sensor have dropped below a predetermined value. Drive for a while.

  The lighting control unit holds the driving state for at least a predetermined period even when the alarm stop operation is determined during the lighting driving.

The lighting control unit does not drive the lighting device when it determines an alarm stop operation during the lighting driving start delay time.

  According to the present invention, when an abnormality such as a fire is detected, the illuminating device is driven only in the case where the human body is detected by the human sensor and the brightness reduction is detected by the brightness sensor. It is possible to evacuate safely by illuminating a part or the whole, and to avoid unnecessary battery consumption by not driving the lighting device during the daytime when no lighting is required.

  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.

  In addition, once the lighting device is driven, the driving state is maintained for a predetermined time, so that the lighting device can be driven without following even if the human detection of the human sensor is repeatedly turned on and off due to the movement of the person. The state can be stabilized.

  In addition, for alarms installed in hallways and stairs, regardless of whether a human body is detected, it is better to drive the lighting device by fire detection to ensure the safety of the evacuation route. When the monitoring cancellation operation of the human sensor is recognized, the lighting device can be driven even when abnormality detection and brightness reduction detection are performed.

  Furthermore, by setting the normal illumination mode to the alarm device installed in the hallway or the like, it is possible to illuminate the feet when a person passes through the monitoring area of the alarm device at night when the illumination is turned off.

  Even if an alarm stop operation is determined during illumination driving, the driving state is maintained for at least a predetermined period. Therefore, even if an alarm stop operation is performed during evacuation, there is no risk that the illumination will immediately turn off and lose visibility. And the foot lighting in the normal lighting mode is not immediately turned off by the alarm stop.

In addition, since a delay time is provided before the start of illumination driving, wasteful power consumption due to illumination driving can be suppressed if an alarm stop operation is performed within the delay time in the case of misinformation or non-fire information.

  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 illuminating device 24 is arranged inside the alarm stop switch 20 as indicated by a dotted line. When the illuminating device 24 is turned on, it passes through the switch cover portion of the alarm stop switch 20 formed of a translucent resin. Illuminate the illumination light to the outside, and illuminate a part or all of the monitoring area where the house alarm is installed. 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 human sensor 26 is disposed on the right side of the alarm stop switch 20 including the lighting device 24. The human sensor 26 detects infrared rays emitted from the human body existing in the monitoring area and outputs a human body detection signal. As the human sensor 26, for example, a known technique such as one using a pyroelectric element can be applied.

  A light / dark sensor 29 is disposed on the upper right portion of the cover 12. The light / dark sensor 29 detects the illuminance of the monitoring area and outputs a brightness detection signal. As the light / dark sensor, for example, a known technique such as one using a photodiode can be applied.

  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 an arbitrary position of the cover 12, and the lighting direction may be fixed to face the floor surface, for example. Further, it may be arranged to be adjustable so as to face an arbitrary illumination direction.

  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.

  As described above, the home alarm devices 10-1 to 10-5 that have determined the fire detection and have output the alarm sound further determine the predetermined lighting control condition based on the detection signals of the human sensor 26 and the light / dark sensor 29. The lighting device 24 is driven 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 warning sound stop process is performed.

  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 alarm device 10-1 includes a CPU 28. For the CPU 28, a wireless circuit unit 30 including an antenna 31, a memory 32, a fire sensor unit 34, a human sensor 26, a light / dark sensor 29, a notification unit 36, and a lighting device 24. An operation unit 38 and a battery power source 40 are provided.

  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 smoke sensor unit 16 is provided in the fire sensor unit 34. In addition to the smoke detector 16, the fire sensor 34 may be provided with, for example, a thermistor that detects the temperature due to fire. In the case of a gas leak monitoring residence guard, a gas leak sensor is provided instead of the fire sensor unit 34.

  The human sensor 26 detects infrared rays emitted from the human body and outputs a human body detection signal. As the brightness sensor 29, a photodiode, a phototransistor, or the like is used, and a brightness detection signal corresponding to the brightness of the monitoring area is output.

  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 and a registration switch 64. 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 64 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 when the three types of fire detection by the fire sensor unit 24 or the other residential alarm devices 10-2 to 10-5, human body detection by the human sensor 26, and brightness reduction detection by the light and dark sensor 29 are determined. Drive.

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

  (3) After the driving of the lighting device 24 is started, the driving state is held for at least a predetermined period.

  (4) When the monitoring release mode of the human sensor 26 initialized by the registration switch 64 is recognized, the lighting device 24 is driven only by the determination of the fire detection and the brightness decrease detection.

  (5) 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.

  Among these, the basic one is the illumination control (1), and the illumination control is performed by selecting and combining (2) to (5).

  In addition, the illumination control unit 62 stops the driving of the lighting device 24 when determining the stop operation by the alarm stop switch 20 during the driving of the lighting device 24. Moreover, the illumination control part 62 can also drive the illuminating device 24 temporarily, when the test operation which operates the alarm stop switch 20 in a regular monitoring normal state is discriminate | determined.

  Further, when the lighting control unit 62 recognizes the setting of the steady lighting mode by the registration switch 64, the lighting device 24 can be driven only by the discrimination of the human body detection by the human sensor 26 and the brightness decrease detection by the light / dark sensor 29. Yes. This steady lighting mode is set to the house guard of the present invention installed in the corridor or staircase, so that the lighting device 24 is automatically driven when going to the toilet at night to illuminate the feet. It can be used as an automatic lighting type lighting device.

  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 flowchart showing a first embodiment of the fire monitoring process according to the embodiment of FIG. 3, and in this embodiment, as described in the above (1), three methods of fire detection, human body detection and brightness reduction detection are performed. The illumination device 24 is driven when it is determined.

  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, in step S2, the fire alarm is monitored, and when the fire alarm by the fire sensor unit 34 or the fire alarm signal from another house alarm is determined, the process proceeds to step S3 to output a fire alarm. . 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, it is determined whether the human body detection by the human sensor 26 and the brightness decrease detection in which the brightness detection signal of the brightness sensor 29 is equal to or less than a predetermined threshold are obtained, and when both detections are determined. It progresses to step S5, the illuminating device 24 is driven, and a part or all of the monitoring area is illuminated.

  During illumination by driving the illumination device 24, it is determined whether or not human body detection and brightness reduction detection are performed in step S6. If human body detection and brightness reduction detection continue, step S7 is skipped, and human body detection and Alternatively, if the brightness reduction detection is cut off, the driving of the illumination device 24 is stopped in step S7.

  Subsequently, in step S8, the presence or absence of an alarm stop operation by the alarm stop switch 20 is determined. When the alarm stop operation is determined, an alarm indicating the interlocking source is stopped in step S9. 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, when it is determined in step S10 that the illumination device 24 is being driven, the drive of the illumination device 24 is stopped in step S11, and the process returns to step S2.

  According to such lighting control of the first embodiment, when a fire alarm is determined, when there is a person in the monitoring area, human body detection is performed, and brightness reduction detection is performed at night Thus, the lighting device 24 is driven to illuminate the monitoring area, so that it is possible to eliminate the waste of illuminating the monitoring area where there is no person even in the daytime or nighttime when the monitoring area is bright.

  FIG. 6 is a flowchart showing a second embodiment of the fire monitoring process according to the embodiment of FIG. 3, and this embodiment is the fire sensor unit 24 or other alarm devices 10-2 to 10-10 as described in (2). After the drive condition according to −5 is established, the lighting device is driven after a predetermined delay time has elapsed.

  The process of FIG. 6 is obtained by adding the processes of steps S25 to S27 to the first embodiment of FIG. 5. Steps S21 to S24 of FIG. 6 are the same as steps S1 to S4 of FIG. Steps S28 to S34 in FIG. 6 are the same as steps S6 to S11 in FIG.

  That is, in the process of FIG. 6, when it is determined in step S24 that the human body is detected and the brightness level is lowered, the elapse of a predetermined delay time is waited in step S25, and the process proceeds to step S28 after the delay time elapses to drive the illumination device 24. is doing. If an alarm stop operation is determined in step S26 during the delay time, the process proceeds to step S27 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.

  FIG. 7 is a flowchart showing a third embodiment of the fire monitoring process according to the embodiment of FIG. 3. In this embodiment, after the driving of the lighting device 24 is started as described in (3), at least the driving state is changed. It is characterized by holding for a predetermined period.

  The processing in FIG. 7 is obtained by adding steps S46 and S47 to the first embodiment in FIG. 5. Steps S41 to S45 in FIG. 7 are the same as steps S1 to S5 in FIG. Steps S48 to S53 of FIG. 7 are the same as Steps S6 to S11 of FIG.

  That is, in the process of FIG. 7, after the lighting device 24 is driven in step S45, a timer is started in step S46, and when a predetermined time has elapsed in step S47, the process proceeds to step S48, where human body detection and brightness reduction detection are performed. The presence / absence is determined, and when the human body detection and / or the brightness decrease detection is cut off at this time, the process proceeds to step S49, and the driving of the lighting device 24 is stopped.

  According to such illumination control of the third embodiment, even if human detection and non-detection by the human sensor 26 are repeated in a short time due to movement of a person in a monitoring area where a fire alarm is issued at night, once When the lighting device 24 is driven, the driving state is continued for a predetermined time, so that the lighting device 24 can be driven stably without being affected by human detection and non-detection of the human sensor 26.

  FIG. 8 is a flow chart showing a fourth embodiment of the fire monitoring process according to the embodiment of FIG. 3, and this embodiment monitors the human sensor 26 initialized by the registration switch 64 as described in (4). When the release mode is recognized, the lighting device 24 is driven only by the determination of the fire detection and the brightness reduction detection even if there is no person.

  8 is obtained by adding steps S64 and S73 to the first embodiment of FIG. 5. Steps S61 to S63 of FIG. 8 are the same as steps S1 to S3 of FIG. Steps S65 to S72 in FIG. 8 are the same as steps S4 to S11 in FIG.

  That is, in the process of FIG. 8, after the fire alarm is determined in step S62 and the fire alarm is output in step S63, if the human body detection cancel mode is determined in step S64, the process proceeds to step S73 to detect the human body. The illumination device 24 is driven without discrimination. Note that in step S63, it is possible to determine whether the brightness has been reduced and to drive the lighting device 24 only at night without a person.

  According to the lighting control of the fourth embodiment as described above, it is desirable to secure lighting for safety evacuation in the event of a fire regardless of the presence or absence of people. By setting the detection cancellation mode, it is possible to ensure safe evacuation by driving the lighting device 24 by determining only the fire alarm and securing illumination such as corridors and stairs as an evacuation route.

  Further, in FIG. 8, in the normal monitoring state in which the fire alarm is not determined in step S62, the illumination device 24 is controlled in the steady illumination mode in steps S74 to S76. That is, if the setting of the steady illumination mode by the registration switch 64 is determined in step S74, the process proceeds to step S75, whether or not there is human body detection and brightness reduction detection is determined. Drive for a predetermined time.

  According to the lighting control based on the setting of the steady lighting mode, for example, by setting the steady lighting mode on the residence guard installed in the hallway, it is installed in the hallway or stairs when going to the toilet at night. The home guard automatically illuminates the feet and can be used as an automatic lighting device.

  FIG. 9 is a flow chart showing a fifth embodiment of the fire monitoring process according to the embodiment of FIG. 3, and this embodiment discriminates an effective alarm stop operation during driving of the lighting device 24 as in (5). In this case, the driving state is maintained for at least a predetermined period.
