Description

The present invention relates to a monitoring system that detects various abnormalities such as a fire, a gas leak, an earthquake, and an intrusion by a detector connected to a transmission line from the receiver and issues an alarm at the receiver.

  Conventionally, there is a disaster prevention monitoring system for facilities such as buildings as a monitoring system for monitoring and alarming abnormalities. In such a disaster prevention monitoring system, for example, a fire detector having a transmission function is connected to the transmission line drawn out from the receiver, and a batch A conversion command is transmitted from the receiver to the fire detector at a certain period. The sensor data such as smoke density and temperature are detected, and then the response is received by sending a polling command specifying the address of the fire detector. The received sensor data is compared with a predetermined threshold value, and the threshold value is set. When it exceeds, it is judged as a fire and a fire alarm is given.

  In addition to disaster prevention monitoring systems, facilities such as buildings are equipped with emergency lighting equipment to ensure safety by turning on an emergency light in the event of a power failure. The emergency lights are turned on for a predetermined time.

  On the other hand, residential alarms (hereinafter referred to as “residential alarms”) that detect and warn of abnormalities such as fires and gas leaks in homes are now in widespread use. There is also an increasing tendency to install fire alarms and monitor abnormalities such as fire in each room.

  In the field of such home alarms, lighting devices are installed in the home alarms, which are turned on as emergency lights in the event of a power failure (Patent Document 1), and when a fire is detected, the light emitting display unit is activated and directed toward the floor. (Patent Document 2) has been proposed which makes it easy to evacuate when a fire occurs at night when the light is turned off and the lighting is turned off.

There is also known an evacuation guidance system that detects a fire and turns on an evacuation guidance lamp (Patent Document 3).

  However, such a conventional monitoring system installed in a building or the like has been carefully considered for on-site confirmation and safety evacuation in the dark when an abnormality such as a fire occurs at night when the lights are off. Therefore, at least the effect of suppressing confusion when an abnormality occurred was insufficient. For example, emergency exit guide lights are scattered in the vicinity of entrances and exits, but this alone has not provided sufficient illumination.

  In addition, in such a conventional monitoring system, linked devices and systems such as lighting and evacuation guide lights must be installed separately from the detector, and the equipment cost and installation, Wiring costs are high. In addition to the detector, there is a problem in terms of space and aesthetics because the installation location and wiring location of the lighting device must be divided.

An object of the present invention is to provide an efficient monitoring system that appropriately illuminates a place where an abnormality such as a fire occurs or an evacuation route.

The present invention relates to a monitoring system for detecting and alarming a fire in a monitoring area by a plurality of detectors connected to a transmission line drawn from a receiver.
The detector
A fire sensor for detecting a fire;
A lighting device that illuminates part or all of the monitoring area;
When determining the reception of an illumination control signal that drives the lighting device to turn on, an illumination determination control unit that drives the lighting device to turn on,
With
The receiver
Stores an interlocking table that registers detectors installed around the detector and / or detectors installed in the evacuation route for each detector as detectors that interlock the lighting when a detector detects a fire. Memory and
When the detector detects a fire, the illumination control signal is transmitted to the detector that recognizes the interlock by referring to the illumination control signal concerned detector and the interlocking table; and
It is provided with.

  The detector further includes a human sensor for detecting a human body, and the illumination determination control unit drives the lighting device to turn on when the reception of the illumination control signal and the human body detection state by the human sensor are determined.

  Alternatively, the detector further includes a light / dark sensor for detecting the brightness of the monitoring area, and the illumination determination control unit determines whether the illumination control signal is received and the brightness decrease detection by the light / dark sensor is detected. Drive on.

Or the detector further
A human sensor for detecting the human body;
A brightness sensor that detects the brightness of the monitoring area;
With
The illumination determination control unit drives and turns on the illumination device when determining the reception of the illumination control signal, the human body detection by the human sensor, and the brightness decrease detection by the brightness sensor.

  Each of the plurality of detectors has a unique address, and the lighting remote control unit transmits the lighting control signal by designating the address of the sensor that detects the fire and the sensor that recognizes the interlock.

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

  According to the present invention, a lighting device is provided in a detector itself such as a fire detector connected to a transmission line from a receiver, and a fire detector detects a fire by remote driving from the receiver when a fire is detected. It is possible to illuminate a part or all of the monitoring area by turning on the surrounding fire detectors or the lighting devices of the fire detectors installed on the blame path, and confirm the fire occurrence site and the safety of the blame path Securing can be realized as a function of a disaster prevention monitoring system without relying on another emergency light facility, response processing in abnormal monitoring such as fire can be performed quickly and appropriately, and safely without causing unnecessary confusion A lighting environment that guides evacuation can be established.

  Since the detector of such a system is installed in a place suitable for installation of the lighting device such as the ceiling or the upper part of the wall surface, it is preferable in this respect to provide the lighting device integrally with the detector, and it is more effective. Lighting can be obtained. At least, there is an effect of efficiently compensating for the shortage of illumination by other illumination devices.

  Also, in conventional monitoring systems, interlocking devices and systems such as lighting and evacuation guide lights must be installed separately from detectors, and equipment costs, installation, and wiring costs increase with the scale and complexity of the system. Etc. can be improved or eliminated.

  In addition, it is possible to improve or eliminate problems in terms of space and aesthetics, such as having to divide the installation location and wiring location of the lighting device separately from the detector.

  In addition, when an abnormality such as a fire is detected, the lighting device is driven only when a human body is detected by a human sensor so that a part or all of the monitoring area can be illuminated and safely evacuated. When the detection is not performed, the power supply capacity of the receiver can be reduced by avoiding unnecessary power consumption by not lighting the lighting device.

  In addition, when an abnormality such as a fire is detected, the lighting device is turned on only when the brightness reduction is detected by the light / dark sensor to illuminate part or all of the monitoring area, and there is no need for illumination. It is possible to avoid unnecessary power consumption by not driving the lighting device during the daytime, and to reduce the power supply capacity of the receiver.

  In addition, when an abnormality such as a fire is detected, the human body is detected by the human sensor and the brightness is detected by the brightness sensor to drive the lighting device to illuminate a part or all of the monitoring area, Even at night when lighting is required, the lighting device can be driven only when there is a person, unnecessary power consumption can be avoided without sacrificing safety, and the power supply capacity of the receiver can be reduced.

In addition, once the lighting device is driven, the driving state is maintained for a predetermined period of time, so that the driving state of the lighting device can be stabilized without following the human sensor and the light / dark sensor even when the sensor is turned on and off repeatedly. Risk factors such as suddenly turning off surrounding lighting during evacuation can be reduced.

  FIG. 1 is an explanatory diagram showing an outline of a disaster prevention monitoring system according to the present invention. In FIG. 1, a transmission line 12 is drawn from a receiver 10 toward a warning area of a facility, and an analog fire detector 14 is connected to the transmission line 12 as a detector.

  A repeater 16 is connected to the transmission line 12, and an on / off type fire detector 20 is connected as a detector to a sensor line 18 drawn from the repeater 16. Furthermore, a gas leak detector 22 is connected to another repeater 16.

  The analog fire detector 14 and the repeater 16 have a transmission function for bidirectionally transmitting information to and from the receiver 10, and a unique address is assigned in advance. As for the number of analog fire detectors 14 and repeaters 16 that can be connected to one transmission line 12, for example, when the maximum number of addresses is 127 addresses, 127 units can be connected.

  The analog fire detector 14 connected to the transmission line 12 is provided with an illuminating device 48. As will be clarified in the following description, when an abnormality such as a fire is detected, the analog fire detector 14 is subjected to remote control from the receiver 10 for illumination. The device 48 is driven to light so that a part or all of the warning area can be illuminated.

  FIG. 2 is a block diagram showing a first embodiment of the disaster prevention monitoring system according to the present invention, and shows details of the receiver 10 and the analog fire detector 14 shown in FIG.

  In FIG. 2, the receiver 10 is provided with a processor 24. The processor 24 is provided with a transmission control unit 26, a display unit 28, an operation unit 30, an acoustic alarm unit 32, and a transfer unit 34. 10 and a power supply unit 36 for supplying power to the analog fire detector 14 via the transmission line 12 is provided.

  Here, the processor 24 includes a CPU, a ROM, a RAM, an AD conversion port, various input / output ports, and the like as hardware. The processor 24 is provided with a disaster prevention monitoring unit 38 and a lighting remote control unit 40 as functions realized by executing the program.

  On the other hand, the analog fire detector 14 is provided with a processor 42, and a transmission control unit 44, a fire sensor 46, and a lighting device 48 are provided for the processor 42. The transmission control unit 44 performs bidirectional data transmission such as commands and data with the transmission control unit 26 provided in the receiver 10.

  The fire sensor 46 detects smoke concentration and temperature associated with a fire. For example, a photoelectric smoke detector is used for detecting smoke concentration, and a semiconductor element such as a thermistor is used for temperature detection.

  The illuminating device 48 uses, for example, a white LED, and illuminates a part or all of the warning area by lighting driving. The illumination device 48 has an illuminance of an appropriate illuminance within a range that can be accommodated in the power supply capacity of the power supply unit 36 provided in the receiver 10. For example, the illumination device 48 can illuminate the same level as an emergency light in an emergency light facility. . Note that the lighting device 48 may be driven intermittently as long as the substantial purpose of illumination can be achieved.

  The processor 42 provided in the analog fire detector 14 is a computer known as a one-chip microcomputer, and includes a CPU, a ROM, a RAM, an AD conversion port, various input / output ports, and the like on one chip.

  The processor 42 is provided with a fire detection processing unit 50 and an illumination control unit 52 as functions realized by executing the program.

  The fire detection processing unit 50 takes in the detection data of the fire sensor 46 and transmits it to the receiver 10 in accordance with an instruction from the receiver 10 in accordance with a fire report transmission algorithm that will be clarified in the following description. When a fire is judged by the disaster prevention monitoring unit 38 provided in the processor 24 of the receiver 10 based on the sensor data from the analog fire sensor 14, the remote lighting control unit 40 provided in the processor 24 detects the fire. An illumination lighting drive command as an illumination control signal is transmitted to the analog fire detector 14.

  The illumination determination control unit 52 may be provided in, for example, the processor 24 on the receiver 10 side, but here, an example provided in the processor 42 on the analog fire detector 14 side as a detector is shown. When the illumination determination control unit 52 provided in the analog fire detector 14 receives the illumination lighting drive command from the receiver 10, it drives the illumination device 48 to illuminate a part or all of the monitoring area.

  The lighting remote control unit 40 of the receiver 10 basically transmits an illumination driving command to the analog fire detector 14 that detects the fire and drives the lighting device 48 to light up when a fire is detected. By sending an illumination drive command to other analog fire detectors installed in the vicinity of the analog fire detector 14 that detects the fire, and lighting them, the fire occurrence area and the adjacent peripheral area are also illuminated. It can be performed.

  Further, when a fire is detected, for example, in the case of a building fire, it is necessary to evacuate the people on the floor where the fire occurred and the upper and lower floors. By sending an illumination drive command to the analog fire sensor 14 installed in the lighting and lighting it, it is possible to illuminate the condemned route and make the condemnation safe.

  Of course, the lighting drive commands may be sent to all the analog fire detectors at the same time and turned on. For example, the lighting fire commands are sent to the analog fire detectors 14 on each floor sequentially and turned on. You can also

  In this way, when the illumination remote control unit 40 transmits an illumination drive command to another analog fire sensor other than the analog fire sensor that has detected a fire, the sensor detects the fire. In this case, whether or not the lighting is to be linked is created in advance as a linked table for each sensor and stored in the memory of the processor 24. When a fire is detected, the sensor that drives the lighting is recognized by referring to this linked table. The illumination drive command is transmitted.

  Here, the fire alarm transmission algorithm in the present embodiment will be described as follows. First, the downstream signal from the receiver 10 to the analog fire detector 14 and the repeater 16 is transmitted in the voltage mode. The voltage mode signal is transmitted as a voltage pulse that changes the voltage of the transmission line 12 between, for example, 18 volts and 30 volts.

  On the other hand, the upstream signals from the analog fire detector 14 and the repeater 16 are transmitted in the current mode. In this current mode, a signal current is passed through the transmission line 12 at the timing of bit 1 of the transmission data, and the upstream signal is transmitted to the receiver as a so-called current pulse train.

  During normal monitoring, the receiver 10 transmits a polling command for normal monitoring in which terminal addresses are sequentially specified, and the analog fire detector 14 and the repeater 16 have polling commands that match their own set addresses. When a message is received, a normal monitoring response is made. Therefore, the receiver 10 can detect the analog fire sensor 14 or the repeater 16 that has not responded to the polling command as a failure.

  Further, the receiver 10 repeatedly transmits a batch AD conversion command every transmission period of a polling command for all sensor addresses. When the analog fire detector 14 receives the batch AD conversion command from the receiver 10, it samples analog detection data such as smoke concentration and temperature detected by the fire sensor 46 and compares it with a predetermined fire level. Yes.

  When the sampled analog detection data exceeds the fire level, an interrupt signal is transmitted to the receiver 10 at a response timing to the polling command. This interrupt signal sends a signal that is not normally used such that the response bit string is all ones.

  The repeater 16 also samples the reception status of the on / off type fire detector 20 or the gas leak detector 22 connected to the detector line 18 based on the batch AD conversion command from the receiver 10 to generate a fire alarm or gas. When a leak is detected, an interrupt signal is transmitted to the receiver 10.

  When receiving the interrupt signal from the analog fire detector 14 or the repeater 16, the receiver 10 issues a group search command, and from the group including the analog fire detector 14 or the repeater 16 that detects the fire. Receive interrupt response to determine group.

  Next, each analog fire detector or repeater included in the identified group is polled in order by specifying addresses, and fire is detected by receiving a fire response such as analog data or fire alarm data. The sensor address of the analog fire sensor 14 or the repeater 16 is recognized and a fire alarm operation is performed.

  Further, the analog fire detector 14 transmits a fire interrupt once, and when the sensor data changes and becomes lower than a predetermined level (fire OFF level) below the fire level when it is not restored, It is determined that the fire is off, and a fire off interrupt is transmitted. The fire OFF level is set to a value slightly lower than the fire level in consideration of hysteresis.

  When the receiver 10 receives the fire OFF interrupt from the analog fire sensor 14, it performs the OFF search process similar to that at the time of the fire interrupt to search for the sensor address where the fire is OFF, and performs the necessary lighting remote control process. .

  FIG. 3 is a flowchart showing an outline of the fire monitoring process executed by the processor 24 provided in the receiver 10 of FIG. The actual fire monitoring process is more complicated, but is simplified here for the sake of simplicity. In FIG. 3, when the power of the receiver 10 is turned on, the processor 24 performs initialization and self-diagnosis processing in step S1, and then checks arrival of sample timing for every predetermined period in step S2.

  When the sample timing is determined, the process proceeds to step S3, where a batch AD conversion command is transmitted to the transmission line 12. Subsequently, in step S4, a polling process for transmitting a polling command by sequentially specifying terminal addresses is executed, and the terminal side is monitored for the presence of a normal response to the transmission of this polling command.

  Subsequently, in step S5, the presence or absence of a fire interrupt is checked, and when a fire interrupt is received, the process proceeds to step S6, a group search by specifying a group address, and a search for a fire detection address sequentially specifying addresses in the subsequent group. In step S7, a fire alarm display in which the sensor address or the relay sensor address (relay address) is specified is performed.

  In step S8, an illumination remote process for transmitting an illumination drive command to the transmission line 12 is executed. In addition to transmitting the illumination drive command specifying the sensor address that detected the fire, this remote lighting processing transmits the illumination drive command specifying the surrounding sensor address, if necessary, or registered in the interlocking table in advance. It is also possible to transmit an illumination drive command specifying a sensor address installed in the designated evacuation route.

  Subsequently, the process proceeds to step S9, where it is determined whether there is a recovery operation. If there is a recovery operation, the recovery process is performed in step S10, and then the process returns to step S2.

  The analog sensor 14 is provided with a warning indicator lamp (red LED or the like) for indicating that a fire has been reported, and the alarm processing of the receiver includes drive control of this warning indicator lamp. The restoration process includes the drive stop control of the indicator lamp.

  On the other hand, if there is no fire interrupt in step S6, a fire OFF interrupt is checked, and when a fire OFF interrupt is received, an OFF search process similar to step S6 is performed in step S12, and a fire OFF process is performed in step S13. Subsequently, in step S8, as an illumination remote control process associated with the fire OFF, the illumination drive stop command is transmitted after the illumination drive holding period is checked.

  FIG. 4 is a flowchart showing an outline of sensor processing by the processor 42 of the analog fire sensor 14 of FIG. The actual fire monitoring process is more complicated, but is simplified here for the sake of simplicity.

  In FIG. 4, the sensor process is started by receiving power supply from the transmission line 12 to the analog fire sensor 14, and after performing initialization and self-diagnosis process in step S <b> 11, the process proceeds to step S <b> 12. Whether or not a batch AD conversion command has been received from is checked.

  When the batch AD conversion command is received, the process proceeds to step S13, and sensor data is sampled by reading the sensor output such as smoke density and temperature output from the fire sensor 46 from the AD conversion port and performing AD conversion.

  Subsequently, in step S14, the sensor data is compared with the fire level. If the sensor data is less than the fire level, if it is determined in step S15 that a polling command specifying the self address is received, a normal response is transmitted in step S16. This response signal includes sensor data analog values such as smoke detection level and temperature detection level.

  On the other hand, if it is determined in step S14 that the sensor data exceeds the fire level and a fire is detected, a fire interrupt is transmitted in step S18. In response to this fire interrupt, a group search command and an in-group search command are sent by a search from the receiver 10, so a response is made to each command and the self-address that detected the fire is received by the receiver. Recognize on the 10th side.

  If it is determined in step S14 that the sensor data is below the fire level, the process proceeds to step S24 to determine whether the fire is off. That is, the analog fire detector 14 transmits a fire interrupt once, and when the sensor data changes and falls below a predetermined level below the fire level (fire OFF level) in a state where it has not been restored, the fire is fired. Determined to be OFF.

  Therefore, the analog fire detector 14 must memorize whether or not it has transmitted a fire interrupt. The fire OFF level is set to a value slightly lower than the fire level in consideration of hysteresis. If it is determined in step 24 that the fire is off, the process proceeds to steps S25 and S26 to perform a predetermined fire off process.

  Subsequently, in step S20, whether or not the illumination drive command is received is checked. If it is determined that the illumination drive command is received, the process proceeds to step S21 to drive and control the illumination device 48 to illuminate part or all of the warning area. To do.

  The lighting drive command is used not only when a fire is detected, but also when, for example, a fire is detected by another analog fire sensor installed nearby, or when the sensor is installed in an evacuation route. Also, the reception of the illumination drive command from the receiver 10 is determined, and the illumination device 48 is driven.

  After driving the illuminating device 48, it is determined whether or not an illumination drive stop command has been received in step S22. If it is determined that an illumination drive stop command has been received, the illumination device 48 is stopped in step S23. At this time, the lighting determination control unit of the analog fire detector 14 may manage the drive holding period of the lighting device 48 and stop the driving of the lighting device 48 after referring to the presence or absence of this period.

  FIG. 5 is a block diagram showing a second embodiment of the disaster prevention monitoring system according to the present invention, and is characterized in that a human sensor is provided on the analog fire detector 14 side.

  5, the configuration of the receiver 10 is the same as that of the first embodiment of FIG. 2, and a human sensor 54 is newly provided on the analog fire detector 14 side as compared with the embodiment of FIG. 2. Is different.

  If the detection status of the human sensor 54 is transmitted to the receiver 10 so that the fire occurrence status and the human body presence status are managed on the receiver side, the illumination determination control unit 52 may be, for example, a processor on the receiver 10 side. 24, the illumination determination control may be performed by the receiver 10, but here, an example provided in the processor 42 on the analog fire detector 14 side as a detector is shown.

  The human sensor 54 detects infrared rays emitted from the human body and outputs a human body detection signal. When the human sensor 54 is newly provided, the illumination determination control unit 52 provided in the processor 42 determines the human body detection by the human sensor 54 when receiving the illumination drive command from the receiver 10. The lighting device 48 is driven on the condition. That is, the illumination control unit 52 drives the illumination device 48 when both the illumination drive command from the receiver 10 and the human body detection of the human sensor 54 are determined.

  Further, when the illumination control unit 52 drives the illumination device 48 based on both the illumination drive command from the receiver 10 and the human body detection from the human sensor 54, the illumination control unit 52 holds the drive state of the illumination device 48 for a predetermined period. To do. As a result, even if the human sensor 54 is repeatedly turned on and off due to movement of a person or the like, an unstable operation that stops driving the lighting device 48 when the human body detection is stopped is eliminated, and stable illumination is performed. The device 48 can be driven to light up for a predetermined time even when the human body is not detected.

  FIG. 6 is a flowchart showing the sensor process of FIG. The processes of steps S31 to S39 in the sensor process of FIG. 6 are the same as the processes of steps S11 to S19 in the first embodiment of FIG. Further, the processing of steps S47 to 49 is the same as the processing of steps S24 to S26 in the first embodiment of FIG.

  Subsequently, in step S40, the presence or absence of human body detection by the human sensor 54 is checked. When the human body detection is determined in step S40 following reception of the illumination drive command in step S39, the process proceeds to step S41 and the illumination device 48 is activated. Drive.

  Subsequently, a timer is started in step S42, and it is determined whether or not a predetermined time has elapsed in step S43. Until the predetermined time elapses, it is checked whether or not an illumination stop command is received in step S46. If no illumination stop command is received, the processing from step S43 is repeated to continue driving the illumination device 48. In other words, during the predetermined time due to the timer start, the driving of the lighting device 48 is continued without depending on the human body detection by the human sensor 54.

  If it is determined in step S43 that the predetermined time has elapsed, the process proceeds to step S44 to check whether or not a human body is detected. If no human body is detected, the process proceeds to step S45 and the driving of the illumination device 48 is stopped.

  If human body detection is determined in step S44, the processing in steps S46 to S43 is repeated. If no human body is detected in step S44, the process proceeds to step S45, and the driving of the illumination device 48 is stopped. In addition, if reception of the illumination drive stop command is determined in step S46 during that time, the process similarly proceeds to step S45, and the illumination device 48 is stopped.

  FIG. 7 is a block diagram showing a third embodiment of the disaster prevention monitoring system according to the present invention. In this embodiment, the analog fire detector 14 is provided with a light / dark sensor.

  In FIG. 7, the receiver 10 is the same as that of the first embodiment of FIG. 2, and the analog fire detector 14 is basically the same as that of the first embodiment of FIG. Provided. A photodiode, a phototransistor, or the like is used as the light / dark sensor 56 and outputs a brightness detection signal corresponding to the brightness of the monitoring area.

  If the detection status of the light / dark sensor 56 is transmitted to the receiver 10 so that the fire occurrence status and the presence status of the human body are managed on the receiver side, the illumination determination control unit 52 may be, for example, the processor 24 on the receiver 10 side. However, here, an example is shown in which the receiver 10 is provided in the processor 42 on the analog fire detector 14 side as a detector.

  When the light / dark sensor 56 is provided, the illumination determination control unit 52 of the processor 42 decreases the brightness at which the detection level of the light / dark sensor 56 becomes a predetermined level or lower when receiving the illumination drive command from the receiver 10. When the detection is determined, the illumination device 48 is driven to illuminate a part or all of the monitoring area.

  FIG. 8 is a flowchart showing the sensor process of FIG. 7. The processes of steps S51 to S69 are basically the same as those of the second embodiment shown in FIG. 6, and human body detection in steps S40 and S44 of FIG. In the third embodiment of FIG. 8, this difference is only different in that the brightness reduction is detected in steps S60 and S64.

  According to the third embodiment in which the light / dark sensor 56 is provided, the lighting device 48 is driven when a fire is detected by the analog fire sensor 14 and the brightness of the warning area is reduced to a predetermined level or less. Thus, part or all of the monitoring area is illuminated.

  FIG. 9 is a block diagram showing a fourth embodiment of a disaster prevention monitoring system according to the present invention. In this embodiment, the analog fire detector 14 is provided with a human sensor and a light / dark sensor. Features.

  The receiver 10 of FIG. 9 is basically the same as that of the first embodiment of FIG. 2, and the analog fire detector 14 is the same as that of the first embodiment of FIG. 2 except that a human sensor 54 and a light / dark sensor 56 are provided. This is the same as the embodiment.

  In the fourth embodiment in FIG. 9, the illumination determination control unit 52 of the processor 42 drives the illumination drive from the receiver 10 with the presence of the human sensor 54 and the light / dark sensor 56 in the analog fire detector 14. When both the detection of the human body by the human sensor 54 and the detection of the decrease in brightness below a predetermined level by the light and dark sensor 56 are determined in a state where the command is received, the lighting device 48 is driven to partially or entirely monitor the area. Will be illuminated.

  FIG. 10 is a flowchart showing the sensor processing of FIG. 9, and the processing of steps S71 to S89 is basically the same as that of the second embodiment shown in FIG. 6, and step S40 in the second embodiment of FIG. , S44 is different from the human body detection check in steps S80 and S84 in the fourth embodiment shown in FIG.

  According to the fourth embodiment of FIG. 10, the human body in the warning area is detected and the brightness is detected in the reception state of the illumination drive command from the receiver 10 when the analog fire detector 14 detects a fire. In the case of the detection of the decrease in brightness in which the brightness drops below a predetermined level, the lighting device 48 is driven.

  Further, the driving of the lighting device is continuously performed for a predetermined time by the timer start, and the driving of the lighting device is stopped by this even when the human detection of the human sensor 54 or the brightness reduction detection by the light / dark sensor 56 is turned on / off. Without this, the lighting device 48 can be driven stably for a predetermined time.

  In the above embodiment, as shown in FIG. 1, the lighting device 48 provided in the analog fire detector 14 is driven based on the lighting drive command from the receiver 10 to partially or entirely of the monitoring area. However, the lighting device 48 may be provided and driven in the on-off type fire detector 20 or the gas leak detector 22 connected to the repeater 16.

  In this case, since the on / off type fire detector 20 connected to the sensor line 18 from the repeater 16 does not have a transmission function with the receiver 10 side, an illumination determination control unit 52 is provided in the repeater 16. The lighting control for each line may be performed, or the on / off type fire detector 20 itself may be provided with a function for turning on the lighting device by a fire alarm operation. Alternatively, an illumination determination control unit may be provided in the receiver 10 and an illumination device drive control line different from the sensor line may be wired from the receiver 10 to the on / off type fire detector.

  On the other hand, since the gas leak detector 22 is connected to the repeater 16 in a one-to-one relationship, the gas leak detector is detected by receiving an illumination drive command from the receiver 10 as in the analog fire detector 14. The lighting device provided in the vessel 22 can be driven. Of course, in this case as well, the illumination control unit 52 can be provided in the repeater 16 or the receiver 10 other than the gas leak detector 22 by appropriately changing the system configuration.

  In the embodiment of the present invention, an example has been described in which the lighting device is turned on based on detection of abnormality of the detector. However, the lighting device can be turned off based on detection of abnormality of the detector.

According to the present invention, a lighting device is provided in a detector itself such as a fire detector connected to a transmission line from a receiver, and a fire detector detects a fire by remote driving from the receiver when a fire is detected. , fire detectors around the, or turns on the illumination device of a fire detector installed in the evacuation path can illuminate a portion or all of the monitor area, confirmation of fire sites and evacuate path Can be realized as a function of the disaster prevention monitoring system without depending on another emergency light equipment, and the response processing in abnormal monitoring such as fire can be performed quickly and appropriately, and without causing unnecessary confusion A lighting environment that can guide evacuation safely can be constructed.

The processor 42 is provided with a fire detection processing unit 50 and an illumination determination control unit 52 as functions realized by executing the program.

The fire detection processing unit 50 takes in the detection data of the fire sensor 46 and transmits it to the receiver 10 in accordance with an instruction from the receiver 10 in accordance with a fire report transmission algorithm that will be clarified in the following description. When a fire is judged by the disaster prevention monitoring unit 38 provided in the processor 24 of the receiver 10 based on the sensor data from the analog fire sensor 14, the remote lighting control unit 40 provided in the processor 24 detects the fire. to analog-type fire detector 14 which transmits the irradiation apparent movement command as a lighting control signal.

The illumination determination control unit 52 may be provided in, for example, the processor 24 on the receiver 10 side, but here, an example provided in the processor 42 on the analog fire detector 14 side as a detector is shown. Lighting determination control unit 52 provided in the analog type fire detector 14 receives the irradiation apparent movement command from the receiver 10, by driving the illumination device 48 illuminates a portion or all of the monitor area.

Further, when a fire is detected, for example, in the case of a building fire, it is necessary to evacuate the people on the floor where the fire occurred and the upper and lower floors. the illumination driving command to the analog type fire detector 14 which is installed by turning it sends, can also be carried out safely evacuation illuminating the evacuation path.

On the other hand, if the fire interrupt is not a step S 5, checks the fire OFF interrupt in step S11, upon receiving the fire OFF interrupt, the same OFF search processing step S6 in step S12, the fire OFF in step S13 Then, in step S8, the illumination drive stop command is transmitted after the illumination drive holding period is checked as the illumination remote control process associated with the fire OFF.

Subsequently, in step S14, the sensor data is compared with the fire level. If it is less than the fire level, it is determined in step S23 whether or not the fire is off. If not, the process proceeds to step S15. If reception of a polling command specifying an address is determined, a normal response is transmitted in step S16. This response signal includes sensor data analog values such as smoke detection level and temperature detection level.

On the other hand, the sensor data in step S14 when determining that a fire beyond the fire level, transmits the fire interrupt at Step S1 7. In response to this fire interrupt, a group search command and an in-group search command are sent by a search from the receiver 10, so a response is made to each command and the self-address that detected the fire is received by the receiver. Recognize on the 10th side.

If it is determined in step S14 that the sensor data is below the fire level, the process proceeds to step S24, where it is determined whether the fire is off or not, but the analog fire detector 14 once transmits a fire interrupt. When the sensor data is changed and falls below a predetermined level below the fire level (fire OFF level) in a state where it has not been restored, it is determined that the fire is OFF.

Therefore, the analog fire detector 14 must memorize whether or not it has transmitted a fire interrupt. The fire OFF level is set to a value slightly lower than the fire level in consideration of hysteresis. When determining the fire OFF in Step 2 3, performs predetermined fire OFF processing proceeds to step S2 4, Step S2 5.

Subsequently it is checked whether the reception of illumination driving command in step S 19, when it is determined to receive the illumination driving command, the process proceeds to step S2 0, the lighting device 48 controls and drives, the surveillance area part or all Illuminate.

After driving the illumination device 48 is to determine the presence or absence of the reception of the illumination drive stop command in step S2 1, when it is determined to receive the illumination drive stop command to stop driving the illumination device 48 in step S2 2. At this time, the lighting determination control unit of the analog fire detector 14 may manage the drive holding period of the lighting device 48 and stop the driving of the lighting device 48 after referring to the presence or absence of this period.

The human sensor 54 detects infrared rays emitted from the human body and outputs a human body detection signal. When the human sensor 54 is newly provided, the illumination determination control unit 52 provided in the processor 42 determines the human body detection by the human sensor 54 when receiving the illumination drive command from the receiver 10. The lighting device 48 is driven on the condition. That is, the illumination determination control unit 52 drives the illumination device 48 when both the illumination drive command from the receiver 10 and the human body detection of the human sensor 54 are determined.

Furthermore, when the illumination determination control unit 52 drives the illumination device 48 based on both the illumination drive command from the receiver 10 and the human body detection from the human sensor 54, the drive state of the illumination device 48 is set for a predetermined period. Hold. As a result, even if the human sensor 54 is repeatedly turned on and off due to movement of a person or the like, an unstable operation that stops driving the lighting device 48 when the human body detection is stopped is eliminated, and stable illumination is performed. The device 48 can be driven to light up for a predetermined time even when the human body is not detected.

FIG. 6 is a flowchart showing the sensor process of FIG. Processing in steps S31~S39 in detector process of Figure 6, to be the same as the processing in steps S11~S19 in the first embodiment of FIG.

If the detection status of the light / dark sensor 56 is transmitted to the receiver 10 so that the fire occurrence status and the brightness of the warning area are managed on the receiver side, the illumination determination control unit 52 is connected to the receiver 10 side, for example, a processor. 24, the illumination determination control may be performed by the receiver 10, but here, an example provided in the processor 42 on the analog fire detector 14 side as a detector is shown.

On the other hand, since the gas leak detector 22 is connected to the repeater 16 in a one-to-one relationship, the gas leak detector is detected by receiving an illumination drive command from the receiver 10 as in the analog fire detector 14. The lighting device provided in the vessel 22 can be driven. Of course, also in this case, the illumination determination control part 52 can be provided in the repeater 16 other than the gas leak detector 22 or the receiver 10 by an appropriate system configuration change.
