By the way, the requirements for the inspection of the built-in emergency power supply have been relaxed for the guide lights included in disaster prevention lighting equipment (see Japanese Industrial Standards JIS C 8105-2-22: 2014 22.3.22A). In other words, if the emergency power supply is a nickel-cadmium storage battery, inspection is not necessary in principle until three years have passed since the year of manufacture. In addition, if the emergency power supply is a nickel-metal hydride storage battery, inspection is not required in principle until it exceeds 5 years from the year of manufacture (Fire Prevention No. 80, Partial Revision of Test Standards and Inspection Procedures for Firefighting Equipment, etc. ( Notice)”).

However, with the relaxation of requirements for inspection of built-in emergency power sources, there is a risk that the timing at which inspection should be performed may be overlooked.

The disaster prevention lighting fixture 1 includes a main body 10, a cover 11 and a pair of supports 12, as shown in FIGS. 1A to 1C. The main body 10 is formed in a bottomed cylindrical shape with one bottom surface (lower surface) open. A pair of supports 12 are attached to the sides of the main body 10 . An annular flange 100 projecting outward is formed at the lower end of the main body 10 .

The pair of supports 12 are formed in the shape of elongated leaf springs. Each support 12 is fixed to the side surface of the main body 10 at one end in the longitudinal direction, and is configured to be able to bend (upward) toward the bottom surface (upper surface) of the main body 10 at the other end in the longitudinal direction. there is That is, the main body 10 is attached to the ceiling material such that the ceiling material is sandwiched between a pair of supports 12 inserted into embedding holes provided in the ceiling and a flange 100 provided on the lower end surface of the main body 10. Supported.

The cover 11 is formed in a disk shape having a larger outer diameter than the flange 100 of the main body 10, and is provided with a circular window hole 110 in the center (see FIG. 1B). The lens 21 of the light source unit 2 is inserted through the window hole 110 . The cover 11 is configured to openably close the opening on the bottom surface of the main body 10 . A pair of mounting springs are attached to the cover 11 . The cover 11 is held by the main body 10 with the bottom surface of the main body 10 closed by the pair of mounting springs (see FIG. 1C).

The light source unit 2 includes an LED (Light Emitting Diode) module 20 and a lens 21 (see FIG. 1B). The LED module 20 emits white illumination light such as white, daylight white, or daylight color when a voltage is applied in the forward direction. The lens 21 is arranged in front of (below) the LED module 20 and collects light emitted from the LED module 20 . However, instead of the LED module 20, the light source unit 2 may include solid-state light-emitting elements such as organic electroluminescence elements or semiconductor laser diodes.

The battery unit 3 has a plurality of unit cells and a battery case housing the plurality of unit cells. The plurality of unit cells are, for example, cylindrical nickel-hydrogen storage batteries or cylindrical nickel-cadmium storage batteries. The battery case is made of an electrically insulating material such as synthetic resin and has a box shape, and accommodates a plurality of unit cells therein.

A circuit configuration of the lighting unit 4 is shown in FIG. The lighting unit 4 includes a charging circuit 40 , a lighting circuit 41 , a control circuit 42 , a notification circuit 43 , a communication circuit 44 , a DC power supply circuit 45 , a power failure detection circuit 46 , a receiver 47 , a monitor lamp 48 and two pushbutton switches 49 . ing.

The DC power supply circuit 45 is composed of, for example, a self-excited switching power supply circuit such as a ringing choke converter. The DC power supply circuit 45 converts the AC voltage supplied from the external power supply 9 (for example, a commercial power system) into a DC voltage lower than the effective value of the AC voltage. The charging circuit 40 operates when power is supplied from the external power supply 9 , and supplies charging current from the DC power supply circuit 45 to the battery unit 3 to charge the battery unit 3 . The lighting circuit 41 converts the DC current supplied from the battery unit 3 into a constant current and supplies the constant current to the light source unit 2 . A power failure detection circuit 46 detects a power failure of the external power supply 9 from the output voltage of the DC power supply circuit 45 and notifies the control circuit 42 of the power failure. The monitor lamp 48 is, for example, a light emitting diode that emits green light. The monitor lamp 48 emits light due to the charging current supplied from the charging circuit 40 to the battery unit 3 . The light emitted from the monitor lamp 48 is emitted forward (downward) of the cover 11 through the first hole 111 provided in the cover 11 . The receiving unit 47 receives a radio signal using infrared rays as a communication medium, demodulates a transmission frame from the received radio signal, and passes it to the control circuit 42 . This radio signal is transmitted from a wireless transmitter operated by an operator performing the inspection work. The receiver 47 receives (receives) the radio signal through the second hole 112 provided in the cover 11 .

The notification circuit 43 has, for example, a display element such as a green LED or a red LED, and an LED drive circuit that drives the display element to emit light. The notification circuit 43 may include a sound generator such as a piezoelectric sounder, and a drive circuit that drives the sound generator to produce a notification sound or notification message. The light emitted from the display element of the notification circuit 43 is emitted forward (downward) of the cover 11 through the first hole 111 provided in the cover 11 . However, the notification circuit 43 may use the monitor lamp 48 as a display element.

Furthermore, the notification circuit 43 may perform notification by visualizing an identifier such as a character, symbol, or pattern. For example, it is preferable that identifiers such as characters such as "It's time for an inspection", symbols such as O and X, and patterns are formed on the cover 11 as watermarks. The notification circuit 43 preferably visualizes the identifier by emitting light emitted from a light-emitting element such as an LED to the outside of the cover 11 through a watermark. The notification circuit 43 may visualize the identifier by displaying it on a display device such as a liquid crystal display.

Communication circuit 44 transmits a communication signal via a communication line. The communication circuit 44 preferably performs two-way communication conforming to a serial communication standard such as RS-485. However, the communication circuit 44 may perform wired communication or power line carrier communication other than RS-485, or may perform wireless communication using radio waves as a medium.

The control circuit 42 operates the charging circuit 40 and stops the lighting circuit 41 when the power failure detection circuit 46 does not detect a power failure. In other words, when the external power supply 9 is not out of power, the light source unit 2 is turned off and the battery unit 3 is charged by the charging circuit 40 . Further, the control circuit 42 stops the charging circuit 40 and operates the lighting circuit 41 when the power failure detection circuit 46 detects a power failure. In other words, when the external power source 9 is out of power, the lighting circuit 41 lights the light source unit 2 (LED module 20 ) with power supplied from the battery unit 3 . Further, when one of the push button switches 49A is pressed or when a transmission frame is received from the receiving unit 47, the control circuit 42 stops the charging circuit 40 and operates the lighting circuit 41 for inspection operation. I do. However, when the other push button switch 49B is pressed, the control circuit 42 can operate the lighting circuit 41 for several seconds, then stop the lighting circuit 41 and operate the charging circuit 40 again. preferable. Each push button of the two push button switches 49A and 49B is arranged so as to face one of the two operation holes 113 provided in the cover 11 (see FIG. 1B).

Here, the control circuit 42 preferably has a microcontroller as a main component. The microcontroller has a CPU (Central Processing Unit), a non-volatile memory storing programs executed by the CPU, one or more timers 420, a real-time clock, an input/output (I/O) port, and the like.

The control circuit 42 counts the usage period of the battery unit 3 with a timer 420 . Note that the "usage period" in this embodiment means the time when a new battery unit 3 is housed in the main body 10 and electrically connected to the lighting unit 4, and charging of the battery unit 3 is started by the charging circuit 40. is the elapsed time from However, the starting point of the usage period may be the time when the new battery unit 3 is fully charged by the charging circuit 40 . Alternatively, the starting point of the usage period may be the date when the battery unit 3 is manufactured. If the date of manufacture of the battery unit 3 is used as the starting point of the period of use, it is desirable to input the date of manufacture of the battery unit 3 to the control circuit 42 using a DIP switch included in the control circuit 42, for example. .

The control circuit 42 outputs a trigger signal to the notification circuit 43 and the communication circuit 44 when the usage period timed by the timer 420 reaches the notification time. Note that the control circuit 42 sets the notification time to a predetermined number of years (eg, 2.8 years) that is two years or more and less than three years when the unit cells of the battery unit 3 are nickel-cadmium storage batteries. In addition, when the unit cells of the battery unit 3 are nickel metal hydride cells, the control circuit 42 sets the notification time to a predetermined number of years (4.8 years, for example) that is four years or more and less than five years. In addition, the control circuit 42 acquires the current time from the real-time clock, and according to a predetermined schedule, triggers in a time zone that can be notified (for example, a time zone when people are in the building where the disaster prevention lighting equipment 1 is installed) It is preferable to output a signal.

When the notification circuit 43 receives the trigger signal from the control circuit 42, the notification circuit 43 notifies that it is time for inspection by causing the display element to emit light. Alternatively, the notification circuit 43 may notify that it is time for inspection by blinking the display element. Further, the notification circuit 43 may cause the piezoelectric sounder to output a notification sound instead of or together with the notification by the display element. The notification sound may be a buzzer sound of "beep" or a voice message such as "Please check." Further, the notification circuit 43 may perform notification using an identifier instead of notification using the display element and notification sound, or together with notification using the display element and notification sound.

When the communication circuit 44 receives the trigger signal from the control circuit 42 , the communication circuit 44 transmits the communication signal to the outside through the communication line 8 . The communication line 8 is, for example, a multi-core (2-core or 4-core) signal cable. The communication line 8 is electrically connected to the relay device 50 (see FIG. 3). A plurality of (two in the illustrated example) relay devices 50 are electrically connected to the management device 51 via the communication line 8 . In other words, the disaster prevention lighting system 5 of the embodiment has a plurality of disaster prevention lighting fixtures 1 , a relay device 50 and a management device 51 . However, the relay device 50 is not an essential component of the disaster prevention lighting system 5 , and a plurality of disaster prevention lighting fixtures 1 may be directly electrically connected to the management device 51 via the communication line 8 .

A plurality of disaster prevention lighting fixtures 1 are multi-drop connected to one relay device 50 via communication lines 8 . For example, one relay device 50 is installed on each floor of a building. A plurality of disaster prevention lighting fixtures 1 installed on the same floor as the relay device 50 are multi-drop connected to the relay device 50 on each floor via the communication line 8 .

Each relay device 50 performs two-way communication (data communication) with (the communication circuit 44 of) a plurality of disaster prevention lighting fixtures 1 multidrop-connected via the communication line 8 by a polling/selecting method. conduct. That is, the relay device 50 cyclically polls (the communication circuit 44 of) a plurality of disaster prevention lighting fixtures 1, and selects (selecting) the disaster prevention lighting fixture 1 (the communication circuit 44 thereof) that is waiting for transmission of a communication signal. to perform one-to-one two-way communication.

The management device 51 is installed, for example, in a management room of a building where the disaster prevention lighting fixture 1 and the relay device 50 are installed. However, the management device 51 may be installed in a place other than the building in which the disaster prevention lighting fixture 1 and the relay device 50 are installed.

The management device 51 has a communication function for bi-directionally communicating with each relay device 50 via the communication line 8, a notification function for notifying inspection timing according to a communication signal received from each disaster prevention lighting fixture 1, and the like. It should be noted that the management device 51 is preferably configured by a computer system. A computer system is mainly composed of a processor and a memory as hardware. The function of the management device 51 in the present disclosure is realized by the processor executing a program recorded in the memory of the computer system. The program may be recorded in advance in the memory of the computer system, may be provided through an electric communication line, or may be recorded in a non-temporary recording medium such as a computer system-readable memory card, optical disk, or hard disk drive. may be provided. A processor in a computer system consists of one or more electronic circuits including semiconductor integrated circuits (ICs) or large scale integrated circuits (LSIs). The integrated circuit such as IC or LSI referred to here is called differently depending on the degree of integration, and includes integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). In addition, an FPGA (Field-Programmable Gate Array), which is programmed after the LSI is manufactured, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit partitions inside the LSI, shall also be adopted as the processor. can be done. A plurality of electronic circuits may be integrated into one chip, or may be distributed over a plurality of chips. A plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. A computer system, as used herein, includes a microcontroller having one or more processors and one or more memories. Accordingly, the microcontroller also consists of one or more electronic circuits including semiconductor integrated circuits or large scale integrated circuits.

Further, it is not an essential configuration of the management device 51 that a plurality of functions (for example, a communication function and a notification function) of the management device 51 are integrated in one housing. may be provided dispersedly in the housing. Furthermore, at least part of the functions (for example, the notification function) of the management device 51 may be realized by the cloud (cloud computing) or the like.

A communication signal transmitted from the communication circuit 44 of the disaster prevention lighting fixture 1 is relayed by the relay device 50 and received by the management device 51 . When receiving the communication signal, the management device 51 acquires the address of the transmission source of the communication signal (unique address assigned to each disaster prevention lighting fixture 1). The management device 51 stores in its memory a data table that associates a unique address assigned to each disaster prevention lighting fixture 1 with information on the installation location of each disaster prevention lighting fixture 1 (for example, the end of the passageway on the second floor). is doing. Therefore, the management device 51 can refer to the data table and obtain the installation location information corresponding to the address of the transmission source. The management device 51 displays the acquired installation location information on the monitor screen of the computer system. Furthermore, the management device 51 notifies that it is time to inspect the disaster-prevention lighting fixture 1 installed at the installation location together with information on the installation location. Therefore, the building manager can perform the inspection work of the disaster prevention lighting fixture 1 according to the content notified from the management device 51 .

As described above, in the disaster prevention lighting fixture 1 of the embodiment, when the usage period of the battery unit 3 timed by the timer 420 reaches the notification time, the notification circuit 43 notifies at least one of light and sound, and the communication circuit 44 transmits a notification communication signal to the outside. Therefore, the disaster prevention lighting fixture 1 not only reports by the reporting circuit 43 but also transmits a communication signal to the outside, so that the inspection timing of the battery unit 3 can be reliably notified. Therefore, even if the requirement for inspection of the built-in emergency power supply is eased, there is less possibility that the time when (the battery unit 3 of) the disaster prevention lighting fixture 1 should be inspected will be overlooked.

Here, when the battery unit 3 is replaced, that is, when the battery unit 3 in use is removed from the main body 10 and a new battery unit 3 is accommodated in the main body 10, the control circuit 42 starts the timer 420. Reset the usage period counted by .

Next, several modifications of the disaster prevention lighting fixture 1 and the disaster prevention lighting system 5 of the embodiment will be described.

In the disaster-prevention lighting fixture 1 of Modification 1, the communication circuit 44 preferably transmits a communication signal using radio waves as a medium. For example, the communication circuit 44 transmits and receives communication signals in compliance with wireless LAN (Local Area Network) standards (IEEE 802.11, etc.) using radio waves in the 2.4 GHz band or the 5 GHz band. However, the communication circuit 44 may transmit and receive communication signals in compliance with the standard for short-range wireless communication (such as IEEE 802.15.1) using radio waves in the 2.4 GHz band.

A communication signal (wireless signal) S1 transmitted from the disaster prevention lighting fixture 1 is received by a communication terminal 6 equipped with a wireless communication function such as a wireless LAN, as shown in FIG. The communication terminal 6 is, for example, a smart phone or a tablet terminal. When the communication terminal 6 receives the communication signal S1 transmitted from the disaster prevention lighting equipment 1, the screen of the display 61 provided on the front surface of the main body 60 displays a message such as "Please inspect." Notification is preferred.

Moreover, in the disaster prevention lighting fixture 1 of the modification 2, it is preferable that the communication circuit 44 transmits a communication signal using visible light as a medium. That is, the communication circuit 44 is a circuit that performs visible light communication, and transmits communication signals by modulating the intensity of visible light. For example, the communication circuit 44 controls the lighting circuit 41 through the control circuit 42 and adjusts the DC current supplied from the lighting circuit 41 to the light source unit 2, thereby modulating the visible light emitted from the light source unit 2. Visible light communication is preferred.

As shown in FIG. 5, the communication signal (visible light radio signal) S2 transmitted from the disaster prevention lighting equipment 1 is received by the portable terminal 7 equipped with an image sensor (an image sensor for capturing still images and moving images). be done. The mobile terminal 7 is, for example, a smartphone with a camera (image sensor), a tablet terminal, or the like. When the portable terminal 7 receives the communication signal S2 transmitted from the disaster prevention lighting equipment 1 through the image sensor, the screen of the display 71 provided on the front surface of the main body 70 displays a message such as "Please inspect." It is preferable to notify by displaying.

The disaster prevention lighting fixture 1 of Modification 3 automatically inspects the battery unit 3 . In the disaster-prevention lighting fixture 1 of Modified Example 3, after the usage period of the battery unit 3 measured by the timer 420 reaches the notification time, the control circuit 42 causes the timer 420 to continue measuring the usage period. Causes the timer to start counting down the inspection period. The inspection period is any period of 6 months or less or 12 months or less.

The control circuit 42 operates the lighting circuit 41 to perform an inspection operation when the time limit of the inspection period by the timer ends. However, if the battery unit 3 is fully charged when the inspection operation is started, the control circuit 42 stops the charging circuit 40, and if the battery unit 3 is not fully charged, it is fully charged. It is preferable to allow the charging circuit 40 to charge until In addition, the control circuit 42 stops the charging circuit 40 and operates the lighting circuit 41 to steadily light the light source unit 2 (for example, full lighting) regardless of the state of charge of the battery unit 3 at the start of the inspection operation. I don't mind if you let me. Alternatively, if the charging current of the charging circuit 40 is sufficiently smaller than the discharging current to the lighting circuit 41, the control circuit 42 operates the lighting circuit 41 while charging the charging circuit 40 (for example, trickle charging). Alternatively, the light source unit 2 may be steadily turned on. The control circuit 42 determines that the battery unit 3 is normal if the lighting circuit 41 is operating normally after a predetermined period of time (20 minutes, 30 minutes, or 60 minutes) has elapsed since the start of the inspection operation. judge. On the other hand, the control circuit 42 determines that the battery unit 3 is not normal (abnormal) if the lighting circuit 41 is not operating normally due to a drop in the output voltage of the battery unit 3 after the predetermined time has elapsed. .

The control circuit 42 outputs a signal (inspection result signal) corresponding to the inspection result (result of determining whether the battery unit 3 is normal/abnormal) to the notification circuit 43 and the communication circuit 44 . The inspection result signal is, for example, a binary signal that becomes low level when the battery unit 3 is normal and becomes high level when the battery unit 3 is abnormal.

Upon receiving the low-level inspection result signal, the notification circuit 43 notifies the inspection result (the inspection result indicating that the battery unit 3 is normal) by blinking the display element at the first cycle. Further, when receiving a high-level inspection result signal, the notification circuit 43 displays the inspection result (inspection result that the battery unit 3 is abnormal) by blinking the display element at a second period shorter than the first period. to be notified.

Upon receiving the inspection result signal from the control circuit 42, the communication circuit 44 transmits a communication signal corresponding to the inspection result signal (low level/high level) to the outside (management device 51, communication terminal 6 or portable terminal 7). Then, the management device 51, the communication terminal 6, or the portable terminal 7 that has received the communication signal reports the inspection result indicated by the communication signal.
