Description

  The present invention relates to an emergency light such as a guide light and an emergency light, and an emergency lighting system.

  Disaster prevention illumination lamps such as guide lights and emergency lights are composed of a lamp, a storage battery, a storage battery voltage monitoring unit, a charging circuit unit, a charging monitor (LED), an energizing circuit unit, a changeover switch, and the like.

  In such an emergency lighting, the energization circuit unit is switched so that the lamp is energized from the commercial AC power supply in a normal state, and the lamp is turned on by energization from the commercial AC power supply. Further, in this normal time, the storage battery is charged through the charging circuit unit by energization from the commercial AC power supply.

  At the time of a power failure in which the energization from the commercial AC power supply is interrupted, the energization circuit unit is automatically switched, and the lamp is turned on by energization from the storage battery.

  Here, the standard that “the lamp can be continuously turned on for 20 minutes or more” is defined for the storage battery. For this reason, it is necessary to periodically inspect whether or not the storage battery satisfies this standard, and this inspection is performed by switching operation of a changeover switch provided in each disaster prevention illumination lamp. Specifically, the energization circuit unit is switched to the same state as at the time of a power failure by switching the changeover switch, and the lamp is energized from the storage battery. In addition, lighting of the lamp by energization from the storage battery at the time of this inspection is continued for 20 minutes, and after 20 minutes, the energizing circuit unit is automatically switched to a normal lighting state, and the lighting of the lamp is energized from the commercial AC power And the charging of the storage battery is resumed.

  Here, when the lamp is turned on by energization from the storage battery, the voltage of the storage battery is monitored by the storage battery voltage monitoring unit, and when it is detected that the voltage of the storage battery has dropped below a predetermined value, The charging monitor flashes when the power is restored to indicate that it is time to replace the battery.

Therefore, the storage battery is inspected by switching the changeover switch, and it is possible to know that it is time to replace the storage battery by checking whether or not the charge monitor is blinking after the inspection.

  Therefore, in this emergency lighting, the power failure switching unit is switched between a normal time and a power failure, and the lamp is lit by energization from a commercial AC power source during normal times, and the lamp is lit by energization from a storage battery at the time of a power failure. Further, the lighting state of the lamp is switched by switching the lighting circuit unit between the normal time and the power failure, and the lighting state of the lamp is monitored by the lighting state monitoring unit.

  This disaster-prevention lighting is connected to a centralized management device provided outside, and when the inspection control signal is transmitted from the centralized management device via the signal transmission / reception unit, the power failure switching unit is switched by the switching control means. First, it is switched to the same state as at the time of a power failure, and is switched to the same state as normal after a predetermined time has elapsed. Whether or not the lighting state is switched from normal lighting to lighting during power failure in the lighting state determination means based on the lighting state of the lamp monitored by the lighting state monitoring unit and the switching state controlled by the switching control means. Is determined, and the determination result is transmitted to the centralized management apparatus via the signal transmission / reception unit. By looking at the determination result transmitted in the centralized management device, it is possible to confirm whether or not switching of the lighting state of the lamp is normally performed.

  According to a second aspect of the present invention, there is provided a lighting system for disaster prevention, wherein the lighting lamp for disaster prevention according to the first aspect is connected to the plurality of lighting lamps for disaster prevention, and the control signal for inspection is switched to the power source for disaster prevention. And a centralized management device that includes a display unit that transmits and receives a signal of a determination result by the lighting state determination unit and displays the result of the received signal.

  Therefore, since the disaster prevention lighting system includes the disaster prevention illumination lamp according to the first aspect, the same actions and effects as those described in the first aspect can be achieved.

  According to the first or second aspect of the invention, by transmitting the inspection control signal from the centralized management device provided outside, the power failure switching unit is first switched to the same state as at the time of the power failure by the switching control means, After a predetermined time has elapsed, the state is switched to the same state as normal. Then, it is determined whether or not the lighting state is switched from the normal lighting to the lighting at the time of power failure based on the lighting state of the lamp monitored by the lighting state monitoring unit and the switching state controlled by the switching control means. Since the determination result is transmitted to the centralized management device, it is possible to easily check whether or not switching of the lighting state of the lamp is normally performed without having to walk around each disaster prevention lighting lamp one by one. .

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the disaster prevention lighting system, FIG. 2 is a block diagram showing the configuration of the disaster prevention illumination lamp, and FIG. 3 is a flowchart showing the control contents during the inspection of the disaster prevention illumination lamp.

  The disaster prevention lighting system according to the present embodiment includes a large number of guide lights 1 which are disaster prevention illumination lights, and a centralized management device 2 to which these guide lights 1 are connected. The central control device 2 includes an operation panel 3 that can perform various operations for transmitting and receiving signals to and from the guide light 1, and a display unit 4 that displays the contents of signals received from the guide lights 1. Yes.

  As shown in FIG. 2, the guide light 1 is composed of a microcomputer or the like in which a control program is stored, and controls a control unit 6, a lamp 7, a storage battery 8, a memory 9, a timer 10, and a power failure switching. Unit 11, storage battery voltage monitoring unit 12, lighting circuit unit 13, lighting state monitoring unit 14, signal transmission / reception unit 15, power circuit unit 16, power failure detection unit 17, charging circuit unit 18, and translucency covering all of these units It is comprised by the cover (not shown) etc. The guide lamp 1 is connected to a commercial AC power source 19.

  The power supply circuit unit 16 converts the current and voltage supplied from the commercial AC power supply 19 into a state suitable for use with the guide lamp 1. The charging circuit unit 18 further converts a part of the current and voltage converted by the current circuit unit 16 into a state suitable for charging the storage battery 8. The power failure detection unit 17 detects whether or not there is a current supply from the commercial AC power source 19, that is, whether the state at that time is normal or a power failure.

  The power failure switching unit 11 performs switching so that the lamp 7 and the control unit 6 are energized from the commercial AC power source 19 during normal times, and switches the energization to the lamp 7 and the control unit 6 and the like from the storage battery 8 during a power failure.

  The storage battery voltage monitoring unit 12 monitors the voltage of the storage battery 8 when the storage battery 8 is energized. The monitored voltage value is sent to the control unit 6.

  The lighting circuit unit 13 switches the lighting state of the lamp 7 by changing the energization state between energization from the commercial AC power supply 19 and energization from the storage battery 8. Specifically, a flat current is applied to the lamp 7 when energized from the commercial AC power 19, and a pulsed current is applied to the lamp 7 when energized from the storage battery 8. Thereby, the lighting state of the lamp 7 becomes darker than usual during a power failure.

  The lighting state monitoring unit 14 monitors whether the lighting state of the lamp 7 is a normal lighting state or a lighting state at the time of a power failure based on a current waveform to be energized. The monitoring result is sent to the control unit 6.

  The memory 9 stores the voltage value monitored by the storage battery voltage monitoring unit 12, the lighting state monitored by the lighting state monitoring unit 14, and the like.

  The timer 10 has a function as a general clock and a function for measuring a predetermined time.

  The signal transmission / reception unit 15 transmits / receives various signals between the control unit 6 of the guide light 1 and the control unit of the centralized management device 2.

  The control unit 6 is provided with storage battery voltage determination means, switching control means, lighting state determination means, and time determination means as functions performed by the CPU according to the control program.

  The storage battery voltage determination means is a function that determines whether or not the voltage of the storage battery 8 monitored by the storage battery voltage monitoring unit 12 is equal to or higher than a predetermined value.

  The switching control means switches the power failure switching unit 11 to the same state as at the time of the power failure when a preset time is reached or when a control signal for inspection is transmitted from the centralized management device 2, and for a predetermined time This is a function for switching to the same state as normal after a lapse.

  The lighting state determination unit is a function of determining whether or not the lighting state monitored by the lighting state monitoring unit 14 matches the switching state controlled by the switching control unit.

  The time determination means is a function for determining whether or not the inspection start time (date) set in advance has been reached.

  Next, the control content at the time of the inspection of the emergency lighting lamp 1 will be described based on the flowchart of FIG. First, it is determined whether or not a preset time (date and time) has been reached (step S1) and whether or not an inspection control signal has been received from the centralized management device 2 (step S2). In step S1, time determination means, which is one of the functions of the control unit 6, is executed. The preset time is, for example, 12:00 every Sunday.

  If it is determined in step S1 that the preset time has been reached (Y in step S1), or if an inspection control signal is received (Y in step S2), the power failure switching unit 11 determines that the power failure has occurred. The state is switched to the same state (step S3), and the switching control means, which is one of the functions of the control unit 6, is executed here. After the power failure switching unit 11 is switched, the timer 10 is started (step S4).

  When the power failure switching unit 11 switches to the same state as that at the time of the power failure, a pulsed current is supplied to the lamp 7, and the waveform of the supplied current is monitored by the lighting state monitoring unit 14. Then, it is determined whether or not the monitoring result matches the switching state controlled by the switching control means, that is, whether or not the lighting state is switched from normal lighting to lighting during power failure (step S5). In addition, a lighting state determination means that is one of the functions of the control unit 6 is executed.

  When the lighting state is not switched to lighting at the time of a power failure (N in Step S5), it means that an abnormality has occurred in the power failure switching unit 11, the lighting circuit unit 13, or the like, and in that case, in Step S5 Is stored in the memory 9 (step S6), the started timer 10 is cleared (step S7), and the power failure switching unit 11 is returned to the normal state by executing the switching control means (step S8). 9 is transmitted to the central management apparatus 2 (step S9).

  If it is determined in step S5 that the lighting state has been switched to lighting during a power failure (Y in step S5), the switching result and the lighting state are stored in the memory 9 (step S10).

  At the time of power failure, the lamp 7 and the control unit 6 are energized from the storage battery 8, and the voltage of the storage battery 8 at this time is monitored by the storage battery voltage monitoring unit 12 (step S11). Then, whether or not the voltage monitored by the storage battery voltage monitoring unit 12 is greater than or equal to a predetermined value is determined in a cycle of a predetermined time (step S12). Here, the storage battery voltage determination which is one of the functions of the control unit 6 is performed. Means are executed. If the voltage of the storage battery 8 is greater than or equal to a predetermined value (Y in Step S12), the voltage value is stored in the memory 9 (Step S13), and whether a predetermined time (power failure state inspection time; 20 minutes) has elapsed It is determined whether or not (step S14). The process of step S11-step S14 is repeated until predetermined time passes.

  When it is determined that the voltage of the storage battery 8 has decreased to a predetermined value or less during the process of step S11 to step S14 (N in step S12), it is time to replace the storage battery 8. In this case, the determination result in step S12 is stored in the memory 9 (step S6), the started timer 10 is cleared (step S7), and the power failure switching unit 11 is executed by executing the switching control means. Is returned to the normal state (step S8), and the contents stored in the memory 9 are transmitted to the centralized management apparatus 2 (step S9).

  If the predetermined time has elapsed without the voltage of the storage battery 8 dropping below the predetermined value while the processing of step S11 to step S14 is repeated (Y in step S14), the timer 10 is cleared (step S15). ), The power failure switching unit 11 is returned to the normal state by the execution of the switching control means (step S16). By returning to the normal state in step S16, a flat current is supplied to the lamp 7, and the waveform of the supplied current is monitored by the lighting state monitoring unit 14. Then, it is determined whether or not the monitoring result matches the switching state controlled by the switching control means, that is, whether or not the lighting state is switched from lighting at power failure to normal lighting (step S17). In addition, a lighting state determination means that is one of the functions of the control unit 6 is executed.

  If it is determined in step S17 that the light has returned to normal lighting (Y in step S17), the return result is stored in the memory 9 (step S18), and the contents stored in the memory 9 (in step S18). The content that the stored restoration is normal and the storage battery voltage stored in step S13) are transmitted to the centralized management device 2 (step S9).

  On the other hand, if it is determined in step S17 that the lighting has not returned to normal lighting (N in step S17), the storage battery 8 has not been replaced, but the power failure switching unit 11, the lighting circuit unit 13, and the like This means that an abnormality has occurred. In this case, the determination result in step S17 is stored in the memory 9 (step S19), and the content stored in the memory 9 (the return stored in step S18 is abnormal). (The storage battery voltage stored in step S13) is transmitted to the centralized management device 2 (step S9).

  When the signal transmitted from each guide light 1 is received by the centralized management device 2, the content of the received signal, for example, which guide light 1 is the time to replace the storage battery 8, Which guide light 1 has an abnormality in the power failure switching unit 11, the lighting circuit 13, or the like is displayed on the display unit 4 of the centralized management device 2.

  In such a configuration, in this disaster prevention lighting system, when it is inspected whether or not the replacement time of the storage battery 8 provided in each guide light 1 has come, the central control device 2 switches to each guide light 1. In response to this, an inspection control signal is transmitted. In each guide lamp 1 to which the control signal for inspection is transmitted, the power failure switching unit 11 is switched to the same state as at the time of the power failure, and the lamp 7 is turned on by energization from the storage battery 8 and the storage battery voltage is monitored at the time of lighting. And the result is transmitted to the centralized management apparatus 2. Therefore, the manager who manages the lighting system for disaster prevention does not have the trouble of looking around each guide light 1 and switching the switch provided in the guide light 1, and is provided for each guide light 1. It is possible to smoothly check that the storage battery 8 is in the replacement period.

  In addition, since the lighting system for disaster prevention has a function of monitoring the lighting state after switching the power failure switching unit 11, it is determined whether or not the switching of the power failure switching unit 11 is normally performed. It can be carried out. For this reason, the failure due to the failure of the switching of the power failure switching unit 11, for example, the guide light 1 is not turned on at the time of a power failure, the energization from the storage battery 8 is continued without returning to the normal energized state after the inspection of the storage battery 8. Generation | occurrence | production of troubles, such as accelerating | stimulating deterioration of the storage battery 8, can be prevented.

  Further, in this lighting system for disaster prevention, even when the central control device 2 does not transmit the inspection control signal to each guide light 1, the power failure switching unit 11 is the same as at the time of power failure when the preset time is reached. It is switched to the state, it is possible to inspect whether the lamp 7 is turned on by energization from the storage battery 8, the storage battery voltage is monitored at the time of lighting, and further whether the power failure switching unit 11 is switched normally, Good maintenance and inspection of the disaster prevention lighting system.
