Description

  The present invention relates to an emergency lighting device such as a guide light.

  The Fire Service Act was revised in 2002, and standards for fire fighting equipment were strengthened. Especially for guide lights, it was necessary to check for emergency lighting at the specified rated time during inspection. Although the emergency lighting at the rated time requires 20 minutes or 60 minutes per guide light, it becomes more burdensome for the operator to check the emergency lighting time one by one as the scale of the facility increases. Therefore, a technique (for example, Patent Document 1) related to a centralized control automatic inspection system for guide lights has been developed and commercialized. In addition, a system has been proposed in which an inspection time, a previous inspection result, and the like are displayed on the screen of the central control room so that a guide light that needs to be inspected can be known and an appropriate inspection can be performed.

JP 2004-111347 A

  The centralized control type automatic inspection system for guide lights requires a control panel that collectively controls the building, and moreover, because it is wired control, there is a problem that large-scale construction is required for installation. In addition, in the case of an individual control type inspection in which an individual instrument is inspected, the inspection is started using a button or a remote control, etc., but the guide light to be inspected for a specified time (for example, an instantaneous power failure or mischief) 24 hours) If the battery is not charged, the automatic inspection operation cannot be performed. For this reason, there is a problem that the inspection cannot be performed and the inspection must be performed again at another opportunity.

  An object of the present invention is to provide a guide light that indicates whether a large-scale work is not required because a control panel is not required, and whether inspection is possible or whether inspection is necessary.

The guide light of this invention is
The guide light lamp is turned on by a commercial power source, and when the power supply from the commercial power source is interrupted, the guide light lamp lamp is turned on by switching to a battery, and the guide light lamp is turned on by the commercial power source. In a guide light that turns off the guide light lamp when a turn-off signal is input to turn it off when
A light source for the monitor;
When a specific pattern signal composed of a specific pattern combined with the presence / absence of the extinction signal is input, it is determined whether or not the battery is charged for a predetermined time or more, and in the predetermined light emission mode corresponding to the determination result, for the monitor And a control unit that emits at least one of the light source lamp and the guide light lamp.

  According to the present invention, it is possible to perform prior confirmation of automatic inspection for a guide light without the trouble of large-scale individual wired wiring and management by providing an address for each guide light.

Embodiment 1 FIG.
In the following embodiment, a guide light 1000 (emergency lighting device) will be described. The guide light 1000 has a function of continuing to charge the battery while turning off the lamp (guide light lamp) with a turn-off signal instructing turning off from the outside during normal use. The lamp for the guide light can be turned off at night or when the room becomes unattended for energy saving. However, prior notification and permission to the local fire department is required.

The turn-off signal is controlled by a guide light signal device 2000, which will be described later, and is originally a turn-off signal from a disaster prevention management room or interlocked with a lock. Even when the light is off, the guide light signal device 2000 operates in response to a signal from the automatic fire alarm facility. When a fire occurs, the guide light signal device 2000 releases the light off state, The guide light is turned on even when unattended. The turn-off signal is generally used together with the power supply wiring without the need for large-scale individual wired wiring or management by providing an address for each guide light.
(1) With this on / off pattern of the extinguishing signal, a “pre-inspection signal” for notifying that the inspection is scheduled is sent from the guide light signal device 2000 to each of the plurality of guide lights. The display screen (guide light lamp), the charging monitor 510, the inspection monitor 520, and the like display the availability of inspection and the summary of the previous inspection result. This facilitates maintenance.
(2) In addition, it is possible to shift to automatic inspection collectively by another on / off pattern based on this extinction signal.

  FIG. 1 is a block diagram of a guide lamp 1000 showing the circuit configuration of the first embodiment. The guide light 1000 includes a display surface 200, a circuit unit 100, a display unit 500, an automatic inspection switch 400, and a battery 300.

  The display surface 200 includes a lamp 201 and a display board (not shown) illuminated by the lamp 201. The lamp 201 is a discharge lamp or a light source composed of a plurality of LEDs.

  The circuit unit 100 includes a lighting circuit 110 that turns on the lamp 201, a turn-off detection unit 150, a control circuit 120, a timer 130, a storage unit 140, and an inspection unit 160.

  The lighting circuit 110 includes a power conversion circuit 111, a commercial power cut-off circuit 112, and a charging circuit 113. The lighting circuit 110 supplies power from a commercial power source or a battery to light the lamp.

  The power conversion circuit 111 converts the AC voltage of the commercial power source into a DC voltage when the commercial power source is supplied, converts the AC voltage into the power supplied to the lamp 201, and when the commercial power source is not supplied (a simulated power failure state described later). In other words, the power is supplied from the battery 300 to be supplied to the lamp 201.

  The commercial power cut-off circuit 112 is a circuit that cuts off the electric power from the commercial power supply directly or indirectly when the battery 300 is inspected. Here, to directly cut off means to cut off by providing a switch or the like on the supply line from the commercial power source. Indirectly shutting off means that the operation of a conversion circuit that converts electric power from a commercial power source into a DC power source or the like is stopped, and the electric power from the battery 300 is supplied to the lamp 201. This is the state where power supply from the power supply is cut off (pseudo power failure state).

The charging circuit 113 is supplied with power from a commercial power source and charges the battery 300.
When operated manually, the inspection switch 114 outputs a signal for directly or indirectly cutting off the power from the commercial power source to the commercial power source cutoff circuit 112.

The control circuit 120 includes a display determination circuit 121. The display determination circuit 121 inputs a turn-off signal for turning off the lamp 201, and causes the lamp 201, the charge monitor 510, the check monitor 520, and the lamp monitor 530 to be turned on in accordance with a check advance signal having a specific pattern that combines the presence or absence of the turn-off signal. A display signal for emitting light in a predetermined manner is output. The control circuit 120 has a function of controlling other components. The control circuit 120 is a microcomputer, for example. The control circuit 120 controls the lighting circuit 110, the timer 130, the storage unit 140, the turn-off detection unit 150, the inspection unit 160, and the like.
The control circuit 120 uses the commercial power cut-off circuit 112 to cut off power supply from the commercial power supply directly or indirectly. Further, the control circuit 120 reads out the inspection result stored in the storage unit 140, determines whether or not the battery is charged for a predetermined time or more, and transmits the determination result, the inspection result, etc. via a lamp, a monitor, etc. Display (light emission).

  The inspection unit 160 receives the control from the control circuit 120, directly or indirectly cuts off the power supply from the commercial power source, lights the lamp 201 with the battery power, and the state of the battery after a predetermined time has elapsed. From this, the quality of the battery is determined.

  The display unit 500 includes a charge monitor 510, an inspection monitor 520, and a lamp monitor 530. These monitors are light sources, for example, LEDs.

  The automatic inspection switch 400 includes a push switch or the like, and when the push switch is pressed, an inspection signal indicating automatic inspection is output to the inspection unit 160. This inspection signal is a signal generated by a long press of the push switch or a pattern that combines the time of pressing the push switch.

  Next, the operation of the normal guide light 1000 will be described. When the commercial power supply (AC100V) is energized, the guide lamp 1000 (lighting device, lighting circuit) lights the lamp 201 and illuminates the display surface 200, thereby indicating an evacuation exit and an evacuation route. Moreover, the battery 300 is charged via the charging circuit 113 included in the guide light 1000 (lighting device), and is prepared for a power failure.

  At this time, while the battery 300 is being charged, the display unit 500 turns on the green charge monitor 510 to indicate that the battery 300 is being charged. The inspection monitor 520 is normally off.

  The guide light 1000 has a turn-off terminal 600 that receives a signal from the guide light signal device 2000. 100 V AC is applied to the extinguishing terminal 600 during normal lighting.

(When receiving a light-off signal)
Here, when the guide light 1000 transmits a turn-off signal from the guide light signal device 2000, the turn-off terminal 600 loses AC 100V. The turn-off detection unit 150 detects this. In the guide lamp 1000, the control circuit 120 executes control for the lighting circuit 110 to turn off the lamp 201 based on the detection result of the turn-off detection unit 150. The battery 300 is continuously charged while saving energy through the above operation. In this case, since the battery 300 is being charged, the charge monitor 510 is lit. The inspection monitor 520 is turned off.

  At this time, when a power failure occurs, the lighting circuit 110 or the light extinguishing detection unit 150 (which may be detected) detects the power failure. Based on the detection of the power failure, the control circuit 120 controls the lighting circuit 110 to turn on the lamp 201 using the battery 300 as a power source regardless of the presence or absence of a turn-off signal, thereby indicating an evacuation exit and an evacuation route.

  The charge monitor 510 is turned off because the battery 300 is being discharged, and the inspection monitor 520 is also turned off.

  When the power is restored from the power failure and the power supply AC100V is applied, the operation returns to the normal operation (continuing charging while turning off the light).

Next, a normal automatic inspection operation that starts when the automatic inspection switch 400 is operated will be described.
FIG. 2 is a flowchart showing a normal automatic inspection operation.

(Prerequisites for inspection)
The control circuit 120 determines whether or not the battery 300 is continuously charged for 24 hours or more. When the battery 300 is continuously charged for 24 hours or more, automatic inspection can be performed. If the battery 300 is not charged for 24 hours or more and the automatic check operation is started, the battery 300 is not charged for 24 hours or more. This is to prevent the battery 300 from being erroneously determined to be abnormal, and is determined based on the standard.

  In the regular lighting, the guide lamp 1000 lights the lamp 201 with a commercial power supply (S11). When the inspection operator performs a predetermined operation on the automatic inspection switch 400, the control circuit 120 starts the inspection. That is, in S12, the control circuit 120 detects an automatic inspection signal generated by operating the automatic inspection switch 400. Specifically, the inspection unit 160 detects a predetermined operation of the automatic inspection switch 400 and outputs the detection result to the control circuit 120.

  Although the operation method of the automatic inspection switch 400 is slightly different depending on each manufacturer, it is not a problem here.

  In S13, the control circuit 120 determines whether or not the battery 300 is charged for 24 hours or more. Information on whether or not the battery is charged for 24 hours is stored in the storage unit 140. This information has already been measured by the control circuit 120 using the timer 130 during charging by the charging circuit 113. When the control circuit 120 determines that the battery 300 is charged for 24 hours or more (yes in S13), the control circuit 120 starts an automatic inspection process (S14).

  When the control circuit 120 shifts to the automatic inspection mode (S14), the power supply from the commercial power supply is cut off using the commercial power cut-off circuit 112, and the lamp 201 is turned on by the battery 300. At this time, the charge monitor 510 is turned off, and the inspection monitor 520 displays that the inspection is in progress such as blinking of the monitor (S15).

  In the automatic inspection mode, the control circuit 120 continuously monitors whether the battery voltage is equal to or higher than a specified value (S16). If it is determined that the battery voltage has not reached the specified value before the rated time is reached, the process proceeds to S19, where the control circuit 120 determines that the battery 300 is abnormal and the battery 300 has reached its end, and ends the inspection at that time. Automatically return to When the operation returns, the control circuit 120 blinks the charge monitor 510 because the battery 300 is abnormal / lifetime, informs the operator of the state of the battery 300 and prompts the battery 300 to be replaced. The control circuit 120 turns off the inspection monitor 520. In addition, the control circuit 120 stores the inspection result in the storage unit 140. In this case, the inspection result means “battery abnormality” (corresponding to row 4 in FIG. 6 described later).

  On the other hand, during the monitoring in S16, if the battery voltage is equal to or higher than the specified value, the control circuit 120 continues to turn on the battery until the rated time (20 minutes or 60 minutes) elapses by measurement using the timer 130, When the rated time has elapsed, the normal lighting mode is automatically restored (S17, S18). If the battery 300 is normal, the control circuit 120 turns on the charge monitor 510, turns off the inspection monitor 520, and performs a normal operation (S18). The control circuit 120 stores the inspection result in the storage unit 300. In this case, the inspection result may be “inspection good” (corresponding to line 1 in FIG. 6 described later) or “no margin” (corresponding to line 2 in FIG. 6 described later). “No margin” means that the battery voltage is equal to or higher than the specified value during lighting at the rated time, but if the voltage value is more than “specified value + margin width ΔV” at the limit of the specified value, the battery voltage is ΔV. This is the case when it is within the range. “Inspection is good” is a case where the battery voltage is equal to or greater than “specified value + margin width ΔV”.

  The above is the normal automatic point sequence shown in FIG.

(Specific pattern signal)
FIG. 3 is a diagram illustrating a “specific pattern signal” composed of a specific pattern in which presence / absence of a turn-off signal transmitted by the guide light signal device 2000 is combined. That is, the “specific pattern signal” is an on / off pattern of the turn-off signal. Reference numeral 11 in FIG. 3 denotes an inspection advance signal among the specific pattern signals. Reference numeral 12 in FIG. 3 denotes a collective inspection signal among the specific pattern signals.
As will be described later, the “pre-inspection signal” is a signal that notifies the guide lamp 1000 (the control circuit 120) in advance that the inspection process will be performed from the guide lamp signal device 2000.
The “collective inspection signal” is a signal for instructing the induction lamp 1000 (control circuit 120) to start automatic inspection, as will be described later.
FIG. 4 is a diagram showing a lighting control system including a guide lamp signal device 2000 and a plurality of guide lights 1000. The above “specific pattern signal” (preliminary inspection signal and collective inspection signal) is sent from one guide light signal device 2000, for example, the guide light 1000-1 to the guide light 1000-6, as in the system shown in FIG. As described above, it is assumed that “specific pattern signals” are transmitted to a plurality of guide lights.

  By transmitting an inspection pre-signal from each of the guide light signal devices 2000 to the respective guide lights 1000, whether or not each guide light 1000 is in a state that can be inspected is displayed on each guide light 1000, thereby enabling inspection. It can be confirmed individually.

  Of course, this inspection advance signal is transmitted by the disaster prevention manager, and it is desirable to transmit it at night, avoiding when there are many people during the day.

  For example, when the on / off pattern of the turn-off signal repeats 3 seconds on and 3 seconds off three times as indicated by 11 in FIG. 3, the control circuit 120 determines that the specific pattern signal is an inspection prior signal. In each guide light 1000, each control circuit 120 displays the state of each guide light (battery charge state). This on / off pattern may be manually operated by a person. In this case, it is important that the interval and the number of times that the control circuit 120 can discriminate between on and off.

FIG. 5 is a sequence of guide lights when an inspection advance signal is received.
FIG. 6 is a diagram showing a display pattern for pre-inspection of the guide light 1000. The operation in this case will be described with reference to FIGS. In S21, the control circuit 120 lights the lamp 201 regularly. When the control circuit 120 detects that the inspection advance signal has been received via the turn-off detection unit 150 (Yes in S22), the control circuit 120 determines whether or not the battery 300 is charged for 24 hours or more (S23). If it is determined that the charging time is less than 24 hours (no in S23), the control circuit 120 causes at least one of the monitor light source and the lamp 201 to emit light in a predetermined light emission mode corresponding to the determination result (S29). . In the example of S29, the control circuit 120 blinks the lamp 201 (for 30 minutes) and turns on the charge monitor 510 as a display indicating that the charging time is insufficient (corresponding to the row 3 in FIG. 6).

  On the other hand, if the control circuit 120 determines that the charging time is 24 hours or longer (yes in S23), it determines whether or not the battery voltage is equal to or higher than a specified value (S24). If it is determined that the battery voltage does not satisfy the specified value (no in S24), the control circuit 120 causes at least one of the monitor light source and the lamp 201 to emit light in a predetermined light emission mode corresponding to the determination result (S30). ). In the example of S30, the control circuit 120 causes the lamp 201 to blink (for 30 minutes) as a display (corresponding to row 4 in FIG. 6) indicating that automatic inspection is not possible (due to insufficient battery voltage), and the charge monitor 510 is Blink.

  When the control circuit 120 determines that the battery voltage is equal to or higher than the specified value (Yes in S24), the control circuit 120 starts display processing indicating that automatic inspection is possible (S25), and proceeds to S26.

  In S26, the control circuit 120 determines whether or not there is a margin in the voltage of the battery 300 in the previous inspection result. The previous inspection result is stored in the storage unit 140 as described in FIG. The control circuit 120 reads the previous inspection result from the storage unit 140, and causes at least one of the monitor light source and the lamp 201 to emit light in a predetermined light emission mode corresponding to the previous inspection result (S27 or S31). That is, in the example of FIG. 5, when the control circuit 120 determines that the previous inspection result is good (Yes in S <b> 26), the control circuit 120 turns on the lamp 201 and turns on the charging monitor 510 and the inspection monitor 520 (FIG. 6). Corresponding to row 1) (S27). Further, in the example of FIG. 5, when the control circuit 120 determines that the previous inspection result is “no margin” (No in S26), the control circuit 120 turns on the lamp 201 and blinks the charging monitor 510, Lights up (corresponding to row 2 in FIG. 6) (S31). Thereafter, the control circuit 120 proceeds to S28 and returns to the regular lighting mode. The display state of each monitor depends on the state of each guide light.

  As described above, the display unit 500 (charge monitor 510) indicating the state of charge of the battery 300 provided in the guide light 1000 and the display unit 500 (inspection monitor 520) indicating the state of inspection by transmitting the inspection advance signal. And the lamp 201 indicate whether the battery 300 can be inspected and the state of the previous inspection result. With this configuration, it is possible to avoid a meaningless discharge even when the inspection switch is accidentally pressed when shifting to automatic inspection and charging is performed for 24 hours.

  In addition, when there are many people in the daytime, the reception time can be received only after 20:00 at night so that the inspection advance signal is not received. Specifically, the timer 130 also serves as a clock function, and the control circuit 120 is configured to respond to an inspection advance signal received in a preset time zone that can be accepted.

  In addition, the signal cancellation of the inspection pre-confirmation returns to the original state by transmitting a similar signal again. In this case, the interval between signal transmission and signal cancellation is set to be accepted after several minutes (for example, 3 minutes).

  Furthermore, the time accuracy can be improved by providing the function of a radio timepiece in the control circuit 120.

(Batch check signal)
Next, the case of the collective inspection signal shown in FIG. 3 will be described. The control circuit 120 has a function of shifting to automatic inspection when receiving a collective inspection signal in which the on / off pattern of the turn-off signal is changed. That is, when the collective inspection signal is received, the same effect as that when the automatic inspection switch 400 is operated is obtained. In this way, by transmitting a collective inspection signal from a single guide light signal device 2000 to a plurality of guide lights, a plurality of guide lights can be inspected at a time. Therefore, it is not necessary to push the automatic check switch of each guide light or shift to automatic check with the remote controller, and the worker can complete the check only by confirming the return state after the automatic check is completed.

  As an operation, the control circuit 120 executes a predetermined battery check process on the battery 300 when the collective check signal (second specific pattern signal) is input. In addition, when the battery check process is executed, the control circuit 120 stores the check result of the battery check process in the storage unit 140.

  In the case of a collective inspection signal, there is no cancellation of the signal, and the end time of the inspection is the same as the normal automatic inspection that ends with the timer 130 incorporated in each guide light. If the state of the guide light is roughly known in advance, the replacement battery 300 to be prepared is also prepared.

  Since it is necessary to check the state of the appliance, clean the lamp, and clean the exterior, inspection by remote control alone is not completed. Considering how you can save waiting time and round trips, you can confirm the general condition from a distance, and the final confirmation only needs to be performed directly under each guide light.
