It is a figure which shows simply the connection relation of the guide light and signal apparatus of Embodiment 1, and the structure of a guide light. 3 is an example of an abnormal signal in the first embodiment. 3 is an example of an abnormal signal in the first embodiment. 3 is an explanatory diagram of a control signal in Embodiment 1. FIG. It is a setting example of the determination range and switching value in Embodiment 2.

(Embodiment 1)
As shown in FIG. 1, in this embodiment, a guide light signal device (hereinafter simply referred to as “signal device”) 1 includes a control unit 11, a determination unit 12, and a notification unit 13. The control unit 11 sends a control signal to the guide light 2 that switches according to the control signal between the normal mode that displays the position of the evacuation exit and the emergency mode that notifies the position of the evacuation exit using a method different from the normal mode. Output. The determination unit 12 determines whether the control unit 11 is normal or abnormal based on the control signal. The notification unit 13 notifies the result of determination by the determination unit 12.

  Hereinafter, the structure of the guide light system 100 in this embodiment is demonstrated in detail. However, the configuration described below is merely an example of the present invention, and the present invention is not limited to the following embodiment, and various modifications can be made according to design and the like.

  As shown in FIG. 2, the guide light system 100 in the present embodiment includes a signal device 1 and a plurality of guide lights 2. Among them, each guide light 2 is attached to the wall above the evacuation exit, and the signal device 1 is installed in a management room in the building. Each guide light 2 is a guide light (hereinafter referred to as an “activation guide light”) having a blinking function that prompts evacuation through blinking and a voice guidance function that prompts evacuation through hearing by emitting sound. Hereinafter, a function that prompts evacuation such as a blinking function and a voice guidance function is referred to as an “activation function”. The signal device 1 is a device that controls the activation function of the guide light 2. The signal device 1 and each guide light 2 are electrically connected, and the signal device 1 can send a control signal for controlling the activation function to each guide light 2.

  Further, the normal mode / emergency mode of the guide lamp 2 is switched based on the voltage value of the input control signal. The normal mode is an operation mode in which the activation function is disabled, and the emergency mode is an operation mode in which the activation function is enabled. The guide light 2 is set with a voltage value (hereinafter referred to as “switching value Vs”) at which the normal mode / emergency mode is switched, and operates depending on the magnitude relationship between the voltage value of the input control signal and the switching value Vs. The mode is determined. For example, when the voltage value of the control signal changes from a state above the switching value Vs to a state below the switching value Vs, the guide light 2 is switched from the normal mode to the emergency mode, and the activation function of the guide light 2 is enabled.

  Moreover, the guide light 2 of this embodiment has the display part 21, the light alerting | reporting part 22, and the audio | voice alerting | reporting part 23. FIG. The display unit 21 includes, for example, a display board on which a pictogram indicating an evacuation direction or an evacuation port is drawn, and an LED (Light Emitting Diode) light source. When the guide lamp 2 is in the normal mode and the emergency mode, the display unit 21 is always lit by power supplied from an AC power supply (for example, 100 V power supply) directly connected to the guide lamp 2. The light notification unit 22 has a blinking function, and when the guide light 2 is in the emergency mode, for example, a xenon lamp blinks. The voice notification unit 23 has a voice guidance function, and when the guide light 2 is in an emergency mode, for example, a speaker or the like generates a guidance voice such as “This is the evacuation exit”.

  As shown in FIG. 1, the signaling device 1 in the present embodiment controls the activation function of the guide lamp 2 in conjunction with the automatic fire alarm facility 3. The automatic fire alarm facility 3 includes, for example, a general automatic fire alarm including a smoke detector 31 installed in each room in a building, a receiver 32 installed in a management room in the building, and the like. Equipment. The smoke detector 31 and the receiver 32 are electrically connected. When the smoke detector 31 detects smoke, the smoke detector 31 sends a signal (hereinafter referred to as “fire signal”) to the receiver 32. In addition, when receiving a fire signal from the smoke detector 31, the receiver 32 transmits a signal (hereinafter referred to as “transfer signal”) to the signal device 1. The signal device 1 performs control for enabling the activation function of the guide light 2 by receiving a transfer signal from the automatic fire notification facility 3.

  In the signal device 1 according to the present embodiment, the control unit 11 includes a power conversion circuit 111 and a switching unit 112. The power conversion circuit 111 is a power supply device for AC / DC conversion that converts, for example, an AC voltage into a DC voltage, and includes a rectifying / smoothing circuit that rectifies and smoothes the AC voltage and a DC / DC conversion circuit that steps down the DC voltage. doing.

  The rectifying / smoothing circuit includes, for example, a diode bridge and an electrolytic capacitor, and rectifies and smoothes an AC voltage from the system power supply. The DC / DC conversion circuit is a step-down chopper circuit including a switching element such as a transistor or a MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor), an electrolytic capacitor, and the like. The DC / DC conversion circuit generates a control signal by stepping down the direct-current voltage output from the rectifying and smoothing circuit. The power conversion circuit 111 is electrically connected to the guide light 2, and the power conversion circuit 111 transmits the generated control signal to the guide light 2.

  A switch 14 is electrically connected between the power conversion circuit 111 and the guide light 2. The switch 14 is a normally closed contact of a relay, for example, and is switched on and off by a signal output from the switching unit 112 (hereinafter referred to as “switching signal”). Thus, the switching unit 112 performs switching between a state in which the control signal is output from the signal device 1 to the guide lamp 2 and a state in which the output of the control signal is stopped.

  In addition, when the signal apparatus 1 has not received the transfer signal from the fire alarm facility 3, the switching signal is not output from the switching unit 112, and the switch 14 is turned on. When the transfer signal from the fire alarm facility 3 is input to the signal device 1, the switching unit 112 outputs a switching signal, and the switch 14 is turned off.

  In the present embodiment, the determination unit 12 is electrically connected between the power conversion circuit 111 and the switch 14. The determination unit 12 detects the voltage value of the control signal output from the power conversion circuit 111 as the detection value V, and determines that the control signal is a normal signal / abnormal signal based on the detection value V. The determination unit 12 is configured by, for example, a microcomputer, and determines that the control signal is a normal signal if the detection value V is within a predetermined determination range V1 to V2 (for example, 22 to 26V). On the other hand, when the detected value V deviates from the determination range, for example, when the detected value V is lower than the lower limit value V1 of the determination range or when the detected value V is higher than the upper limit value V2 of the determination range, the control signal is abnormal. It is determined that it is a signal.

  FIG. 3 shows a case where the detection value V detected by the determination unit 12 is a constant value lower than the lower limit value V1 of the determination range. FIG. 4 shows a case where the detection value V fluctuates with time and falls below the lower limit value V1 of the determination range intermittently. 3 and 4, the vertical axis represents voltage and the horizontal axis represents time. When it is determined that the control signal is an abnormal signal as described above, the determination unit 12 outputs a notification signal to the notification unit 13.

  The alerting | reporting part 13 is comprised by sound alerting devices, such as light alerting devices, such as LED, and a sound buzzer, for example. When the notification unit 13 receives the notification signal from the determination unit 12, the notification unit 13 notifies the periphery of the signal device 1 that the control signal output from the power conversion circuit 111 is an abnormal signal.

  Hereinafter, the operation of the guide light system 100 in the present embodiment will be described in detail.

  As described above, there are two types of operation of the guide light 2: a normal mode and an emergency mode. In the normal mode, the activation function of the guide light 2 is stopped and the display unit 21 is lit. In the emergency mode, since the activation function of the guide light 2 is enabled, in addition to the display unit 21 being lit, the light report unit 22 blinks and the voice report unit 23 emits a guide voice.

  FIG. 5 shows a case where the vertical axis is the voltage of the control signal output from the signal device 1 to the guide lamp 2, the horizontal axis is time, and the voltage of the control signal is changed with time. As shown in FIG. 5, the guide lamp 2 operates in the normal mode in the output state A in which a control signal (for example, a DC voltage of about 24 V) is output from the signal device 1 to the guide lamp 2. On the other hand, in the output stop state B in which the output of the control signal from the signal device 1 is stopped, the guide lamp 2 operates in the emergency mode.

  During normal times when no fire has occurred, the signal device 1 does not receive a transfer signal from the automatic fire alarm facility 3. Therefore, the signal device 1 does not output a switching signal for turning off the switch 14, and the switch 14 is turned on. In this case, since the control signal output from the power conversion circuit 111 is in the output state A where the control signal is input to the guide lamp 2, the guide lamp 2 operates in the normal mode.

  On the other hand, in the event of a fire or the like, the smoke detector 31 installed in the vicinity of the fire site senses smoke, and the fire alarm facility 3 transmits a transfer signal to the signal device 1. The signal device 1 receives a transfer signal from the automatic fire alarm facility 3 and outputs a switching signal for turning off the switch 14, so that the power conversion circuit 111 and the guide light 2 are electrically disconnected. As a result, the control signal output from the power conversion circuit 111 is not input to the guide lamp 2 and is in the output stop state B, so that the guide lamp 2 operates in the emergency mode. In this way, the guide light 2 notifies the surrounding people of the evacuation direction or the location of the evacuation exit.

  Here, there is a possibility that the control signal becomes an abnormal signal due to an abnormality of the components constituting the power conversion circuit 111. As an example in which the control signal becomes an abnormal signal, when the electrolytic capacitor included in the power conversion circuit 111 reaches the end of its life and the capacitance of the electrolytic capacitor decreases, the smoothing ability of the electrolytic capacitor may decline. As a result, the control signal output from the power conversion circuit 111 becomes an abnormal signal having a relatively large ripple (fluctuation) as shown in FIG.

  When the control signal becomes an abnormal signal, the guide light 2 that has received the abnormal signal may malfunction. For example, it is assumed that the guide light 2 whose switching value Vs for switching from the normal mode to the emergency mode is 20 V is connected to the power conversion circuit 111. In this case, if the control signal output from the power conversion circuit 111 becomes an abnormal signal and the minimum value of the abnormal signal is 20 V or less, the guide lamp 2 is switched to the emergency mode. As described above, there is a possibility that the guide light 2 is switched to the emergency mode and malfunctions even though the automatic fire notification facility 3 is not outputting the transfer signal to the signal device 1.

  Here, if the signal apparatus 1 has the determination part 12 and the alerting | reporting part 13 like this embodiment, the above malfunctions of the guide light 2 can be prevented. When the control signal output from the power conversion circuit 111 becomes an abnormal signal, the determination unit 12 immediately detects the abnormal signal and outputs the notification signal to the notification unit 13. Upon receiving the notification signal, the notification unit 13 notifies the surroundings that the power conversion circuit 111 is outputting an abnormal signal, that is, that the control unit 11 is abnormal. The surrounding people who have received the notification by the notification unit 13 request inspection and repair of the power conversion circuit 111 before the guide lamp 2 malfunctions due to the abnormal signal. Thereby, the malfunctioning of the guide light 2 can be prevented.

  As described above, according to the guide light system 100 of the present embodiment, the determination unit 12 detects the voltage value of the control signal output from the power conversion circuit 111 and determines normality / abnormality of the detected value. If the detection value is abnormal as a result of the determination, the notification unit 13 notifies the outside that the power conversion circuit 111 is abnormal. The persons around the signal device 1 that have received the notification request inspection and repair of the power conversion circuit 111 before the guide light 2 malfunctions. Therefore, since the guide light signal device 1 and the guide light system 100 of the present embodiment can take appropriate measures such as inspection and repair before the guide light 2 malfunctions, the malfunction of the guide light 2 is prevented in advance. be able to.

  The power conversion circuit 111 is not limited to a switching circuit system using a switching element. For example, the power conversion circuit 111 has a circuit configuration in which an AC power supply voltage is stepped down by a step-down transformer, rectified by a rectifier element, and smoothed by an electrolytic capacitor or the like. Also good. In this case, when the smoothing ability of the electrolytic capacitor declines due to the life or the like, the control signal output from the power conversion circuit 111 may become an abnormal signal having a relatively large ripple. In addition, even when the step-down capability deteriorates due to deterioration of the step-down transformer or the like, the control signal output from the power conversion circuit 111 may become an abnormal signal that deviates from the determination range. Thus, even if the control signal becomes an abnormal signal, the determination unit 12 and the notification unit 13 of the present embodiment detect the abnormality of the power conversion circuit 111 in advance and notify the surroundings of the malfunction, thereby causing the malfunction of the guide light 2. Can be prevented in advance.

  In the present embodiment, the notification unit 13 is provided in the signal device 1, but the notification unit 13 may be added to the outside separately from the signal device 1.

  In the present embodiment, the activation function of the light reporting unit 22 and the voice reporting unit 23 is effective in an emergency. However, when a fire has occurred in the vicinity of the guide light 2, it is desirable that the activation function of the guide light 2 is disabled. Therefore, the guide light 2 may have a smoke sensor that is directly connected, and when the smoke sensor senses smoke, it may be configured to output a stop signal that disables the activation function of the guide light 2. Further, when an emergency broadcast flows in a building in an emergency, it is desirable that the guidance voice of the voice notification unit 23 is invalid. Therefore, the signal apparatus 1 may be configured to stop the voice guiding unit 23 during emergency broadcasting.

  In addition, the guide light 2 may have a reserve power source such as a built-in storage battery, and the display unit 21 may be lit in an emergency when a power failure occurs. Furthermore, the guide light 2 may have a confirmation unit for operation confirmation, and the operation may be confirmed by the confirmation unit at the time of inspection.

  Further, the switch 14 may be provided outside the signal device 1 and controlled by a signal output from the signal device 1.

  As in this embodiment, the determination unit 12 determines that the control signal is normal if the voltage value is within a predetermined determination range, and determines that the control signal is abnormal if the voltage value of the control signal is outside the determination range. It is desirable to be configured. Thereby, the determination part 12 becomes a simple structure. In addition, the determination unit 12 can clearly determine the control signal.

  The control unit 11 desirably includes a power conversion circuit 111 that generates a control signal including a DC voltage by converting an AC voltage into a DC voltage as in the present embodiment. Thereby, the determination part 12 and the alerting | reporting part 13 become useful, and can determine normally / abnormality of the signal apparatus 1 always.

  Moreover, it is desirable that the guide light system 100 includes the signal device 1 and at least one guide light 2 as in the present embodiment. However, when the guide light system 100 includes a plurality of guide lights 2, it is sufficient that at least one guide light 2 has an activation function, and only the display unit 21 is included in the plurality of guide lights 2. A guide light 2 may be included. Thereby, the operation of all the guide lights 2 having the activation function can be controlled by the control signal output from one signal device 1.

(Embodiment 2)
In the guide light system 100 of the present embodiment, the lower limit value V1 of the determination range for the determination unit 12 to determine normality / abnormality is a value equal to or greater than the voltage value at which the guide light 2 switches from the normal mode to the emergency mode. This is different from the first embodiment.

  For example, when the switching value Vs of the guide light 2 is 20V and the lower limit value V1 of the determination range of the determination unit 12 is 10V, the guide light 2 may malfunction. That is, in this case, when the control signal output from the power conversion circuit 111 becomes 19 V, for example, the determination unit 12 determines that the control signal is normal, but the guide light 2 is switched to the emergency mode. Thus, when the switching value Vs is higher than the lower limit value V1 of the determination range, the determination unit 12 cannot determine the abnormality of the power conversion circuit 111 before the guide light 2 is switched to the emergency mode, and the guide light 2 may malfunction. There is sex.

  On the other hand, when the switching value Vs of the guide light 2 is 10V and the lower limit value V1 of the determination range of the determination unit 12 is 20V, malfunction of the guide light 2 can be prevented. FIG. 7 shows a state where the detection value V is lower than the switching value Vs when the vertical axis is voltage and the horizontal axis is time, and the lower limit value V1 of the determination range is set higher than the switching value Vs. In this case, when the control signal output from the power conversion circuit 111 becomes 19 V, for example, the determination unit 12 determines that the control signal is an abnormal signal, and the notification unit 13 causes an abnormality of the power conversion circuit 111 around the signal device 1. Is notified. At this time, since the voltage value of the control signal is higher than the switching value Vs, the guide lamp 2 operates in the normal mode.

  The lower limit value V1 of the determination range is desirably a value equal to or higher than the voltage value at which the guide light 2 that switches between the normal mode and the emergency mode is switched to the emergency mode according to the voltage value of the control signal as in the present embodiment. When the lower limit value V1 of the determination range is higher than the switching value Vs, the determination unit 12 can determine the abnormality of the power conversion circuit 111 before the guide light 2 is switched to the emergency mode. In addition, the notification unit 13 notifies the abnormality of the power conversion circuit 111 around the signal device 1, and the person who has received the notification requests inspection and repair of the power conversion circuit 111, so that the malfunction of the guide light 2 is caused in advance. Can be prevented.
