Description

  The present invention relates to an emergency light inspection system having an inspection function of a secondary battery that serves as a power source for an emergency light during a power failure.

  A conventional lighting device such as a guide light or an emergency light includes a light source such as a guide light or an emergency light and a secondary battery of an emergency power source. When a power failure occurs due to a fire or an earthquake, the secondary battery The light source is turned on with electric power. Such a lighting device is obliged to regularly check whether or not the emergency lighting of the light source by the secondary battery is normally performed according to rules such as the Notification of the Fire Department and the Building Standard Law.

  FIG. 6 is a block diagram of a conventional emergency light lighting device. The emergency light lighting device shown in this figure includes an emergency light 11, a secondary battery 12, a charging unit 13 for charging the emergency light 11, a power failure detection unit 14 for detecting a power failure of the external power source AC, and the power of the secondary battery 12. , The emergency light lighting unit 15 that lights the emergency light 11 when a power failure is detected by the power failure detection unit 14. The emergency light lighting device is provided with a switch unit 16 for forcibly cutting off the power supply path from the external power supply AC to the emergency light 11 to enter a pseudo power failure state. The drawstring 161 is suspended.

  An inspector who performs an inspection based on the above rules operates the pull cord 161 to set a predetermined inspection time based on the rules and a pseudo power outage, and supplies power to the emergency light 11 only from the secondary battery 12. The emergency light 11 is turned on. Since the inspection time is defined as 30 minutes, the inspector monitors whether or not the emergency light 11 is normally lit during that time.

  However, the above monitoring must be performed for each emergency light lighting device installed in each place in the building, which is a very time-consuming work. Therefore, the system is designed to automate the inspection work and save labor. Various proposals have been made.

In addition to the emergency light 11 and the secondary battery 12, a charging unit 13 and a power failure are provided. The detection unit 14, the emergency light lighting unit 15, the switch unit 16, the communication unit 17, and the inspection unit 10 are configured.

  The charging unit 13 charges the secondary battery 12 using power from an external power source (commercial power source) AC. For example, AC-DC that converts AC power from the external power source AC into DC power at a predetermined voltage level. Consists of a converter and the like.

  The power failure detection unit 14 detects a power failure of the external power source AC. In the example of FIG. 1, the power failure detection unit 14 detects the current or voltage from the external power source AC between the switch unit 16 and the charging unit 13. It is configured to detect a power failure of the power supply AC. Note that the present invention is not limited to this configuration, and a configuration in which a current or voltage from the external power source AC is detected between the external power source AC and the switch unit 16 or between the charging unit 13 and the secondary battery 12 may be used.

  The emergency light lighting unit 15 uses the power of the secondary battery 12 to light the emergency light 11 when a power failure is detected by the power failure detection unit 14. As a specific example, a switch part of a normally open contact that is provided in the input (output of the secondary battery 12) and is closed when a power failure is detected by the power failure detection unit 14, and through this switch unit. And an inverter connected to the output of the secondary battery 12.

  In addition, when a power failure is detected by the power failure detection unit 14, the emergency light lighting unit 15 supplies power (voltage / current) for instantaneous emergency lighting to the emergency light 11, as shown in FIG. , Configured to supply at least until the power failure is restored at the rated current.

  Furthermore, when the inspection unit 10 performs an inspection to be described later, the emergency light lighting unit 15 performs power for the above-described instantaneous emergency lighting as shown in FIG. 3 according to the inspection lighting control signal from the inspection unit 10. Electric power having a slower rate of change than (voltage / current) is supplied to the emergency light 11 for a predetermined inspection time (for example, 30 minutes). In the example of FIG. 3, a current that has an inrush current and a steady current that are equal to or lower than the rated current of the emergency lamp 11 is supplied to the emergency lamp 11. In the figure, a voltage with a slower temporal change rate than the voltage for instantaneous emergency lighting is applied to the emergency light 11, so that the temporal change rate is higher than the current for instantaneous emergency lighting. However, the present invention is not limited to this, and the current may be controlled or limited so as not to exceed the steady current. Also good.

  Returning to FIG. 1, the switch unit 16 is a switch such as a relay having a normally closed contact provided on the external power supply AC side of the secondary battery 12. In the example of FIG. 1, the switch unit 16 is configured to be interposed between the external power source AC and the charging unit 13, but is interposed between the charging unit 13 and the secondary battery 12. It may be configured.

  The communication unit 17 is for receiving an inspection control signal from the control panel 2 via the communication line L. Note that the communication unit 17 may communicate with an unbalanced communication system in which the control panel 2 is a main station and the emergency light lighting device 1 is a slave station, or is connected to a communication line L as a network for constructing a LAN. The communication may be performed using a balanced communication method.

  The inspection unit 10 performs inspection based on a predetermined rule by opening the normally closed contact of the switch unit 16 and turning on the emergency light 11 by the emergency light lighting unit 15. As one specific example, the inspection unit 10 includes a time measuring function and a detector that detects the output voltage of the secondary battery 12. Then, the inspection unit 10 opens and closes the normally closed contact of the switch unit 16 and the normally open contact of the emergency light lighting unit 15 according to the inspection control signal received via the communication unit 17, and also performs inspection lighting control. A signal is output to the emergency light lighting unit 15 to start timing, and when the measured time reaches an inspection time (for example, 30 minutes) based on the above rule, detection is performed by the detector, and 2 based on the detection result. The determination result of the normality / abnormality of the secondary battery 12 is configured to be transmitted to the control panel 2 via the communication unit 17. Here, the voltage value of the detection result is compared with the reference voltage value, and if it is equal to or higher than the reference voltage value, it is determined that the secondary battery 12 is normal, otherwise it is determined that the secondary battery 12 is abnormal. Is done.

  Note that the inspection unit 10 is not limited to the configuration of this specific example, and includes a timer function and a detector that detects the output voltage and output current of the secondary battery 12, and is received via the communication unit 17. According to the inspection control signal, the normally closed contact of the switch unit 16 and the normally open contact of the emergency light lighting unit 15 are opened and closed, respectively, and the inspection lighting control signal is output to the emergency light lighting unit 15 to start timing. Until the time measured reaches the inspection time based on the above rule, detection is performed by the detector every predetermined period, and each detection result for each predetermined period, or the emergency light 11 and the secondary battery 12 based on these detection results. The normal / abnormal determination result may be transmitted to the control panel 2 via the communication unit 17.

  The control panel 2 controls each emergency light lighting device 1 and includes a communication unit 21 and a control unit 20. The communication unit 20 is for communicating with each emergency light lighting device 1 via the communication line L.

  The control unit 20 is configured by, for example, a microcomputer and executes processing such as control of each emergency light lighting device 1. For example, at the time of inspection based on a predetermined rule, a process of outputting an inspection control signal to a specific emergency light lighting device 1 via the communication unit 20 is executed. Needless to say, identification information of each node for identifying a communication partner is stored in advance in the memory of each node as basic communication information.

  Next, the operation of the emergency light inspection system configured as described above will be described. First, the operation when a power failure occurs will be described. When a power failure occurs, in each emergency light lighting device 1, a power failure is detected by the power failure detection unit 14, and power for instantaneous emergency lighting from the emergency light lighting unit 15 is supplied to the emergency light 11 at least until the power failure is restored. As a result, each emergency light 11 is instantly lit and keeps the emergency lighting at least until the power failure is restored.

  Next, the operation at the time of inspection will be described. In the control panel 2, when an emergency light inspection schedule for an emergency light lighting device 1 is reached, an inspection control signal is output to the emergency light lighting device 1.

  In the emergency light lighting device 1, when the inspection unit 10 receives the inspection control signal, the normally closed contact of the switch unit 16 and the normally open contact of the emergency light lighting unit 15 are opened and closed, respectively. When the normally closed contact of the switch unit 16 is opened, a pseudo power failure occurs, and when the normally open contact of the emergency light lighting unit 15 is closed, the inverter of the emergency light lighting unit 15 is activated. .

  In addition, an inspection lighting control signal is output to the emergency light lighting unit 15 and time measurement is started. When the inspection lighting control signal is received by the emergency light lighting unit 15, power having a slower temporal change rate than the power (voltage / current) for instantaneous emergency lighting is supplied to the emergency light 11. . As a result, the emergency light 11 is gradually turned on.

After that, when the timekeeping time reaches the inspection time based on the above rule, detection is performed by the detector, and the determination result of normality / abnormality of the secondary battery 12 based on the detection result is controlled from the emergency light lighting device 1. It is transmitted to the board 2. The determination result is received by the control panel 2 and managed and held.
Similarly, based on the emergency light inspection schedule, the inspection control signal is output to the other emergency light lighting devices 1 and the same operation as described above is performed.

  As described above, according to the first embodiment, when inspection is performed, a current with a slower temporal change rate is supplied to the emergency light 11 than a current for instantaneous emergency lighting at the time of a power failure of the external power source AC. Therefore, it is possible to prevent the life of the emergency light 11 from being shortened by inspection based on a predetermined rule.

  Further, as shown in the example of FIG. 3, when the emergency light lighting unit 15 is inspected by the inspection unit 10, a current that causes the inrush current and the steady current to be equal to or lower than the rated current of the emergency light 11 is supplied to the emergency light 11. Therefore, the life of the emergency light 11 can be prevented from being shortened by inspection based on a predetermined rule, and the filament of the emergency light 11 can be prevented from being cut by an inrush current.

(Embodiment 2)
4 and 5 are operation explanatory views of the emergency light inspection system according to the second embodiment of the present invention.

  In the emergency light inspection system of the second embodiment, as a difference from the first embodiment, the control panel 2 transmits a regular inspection control signal or a preliminary inspection control signal as an inspection control signal to each emergency light lighting device 1. The emergency light lighting device 1 operates according to a regular inspection control signal or a preliminary inspection control signal from the control panel 1.

  Specifically, the control panel 2 operates according to the emergency light inspection schedule in the same manner as in the first embodiment, but as a difference from the first embodiment, each inspection is performed via the communication unit 21 during inspection based on a predetermined rule. While the regular inspection control signal is output to the emergency light lighting device 1, the preliminary inspection control signal is output to each emergency light lighting device 1 via the communication unit 21 during the preset preliminary inspection. .

In the emergency light lighting device 1, the communication unit 17 receives the rule inspection control signal or the preliminary inspection control signal, and the inspection unit 10 receives the rule inspection control signal or the preliminary inspection control signal received via the communication unit 17. It is configured to perform a rule check or a preliminary check, respectively.
The operation of the inspection unit 10 itself is in accordance with the regular inspection control signal or the preliminary inspection control signal, except that the regular inspection lighting control signal or the preliminary inspection lighting control signal is output to the emergency light lighting unit 15 as the inspection lighting control signal. Although it is the same as that of Embodiment 1, a detection result is different when the emergency light lighting part 15 performs different operation | movement according to those control signals.

  That is, when the inspection unit 10 performs a regular inspection, the emergency light lighting unit 15 is more in accordance with the regular inspection lighting control signal from the inspection unit 10 than the electric power for instantaneous emergency lighting as in the first embodiment. The rate of change with time is moderated, and the power for which the current for emergency lighting and the steady level are set to the same level are supplied to the emergency light 11 for a predetermined inspection time. On the other hand, when the preliminary inspection is performed by the inspection unit 10, the emergency lamp lighting unit 15 is in accordance with the preliminary inspection lighting control signal from the inspection unit 10 as shown in FIG. An inspection in which the rate of change with time is moderated, and the power whose steady level is lower than the current for emergency lighting is set to be the same as the power consumption of the secondary battery 12 by the emergency light 11 during the inspection based on a predetermined rule. Supplied to emergency light 11 for hours.

  Here, the relationship between the number of times the power is turned on / off with respect to the emergency light 11 and the life of the emergency light 11 will be described. As shown in FIG. 5, the continuous lighting time (life) from the initial lighting until the filament breaks is T. When the power is turned on / off, the filament is more likely to be cut by the inrush current when the power is turned on, and the time until the filament is cut is shorter than T.

  For this reason, in the first embodiment, in order to prevent the filament from being easily cut by an inrush current when the power is turned on, the inrush current does not exceed the rated current, in other words, no inrush current exceeding the rated current is generated. As described above, the rate of change with time is made slower than the current for instantaneous emergency lighting.

  In the second embodiment, in addition to the above, in order to enable more accurate abnormality detection, the inspection is performed more than the number of inspections based on a predetermined rule, and the life of the emergency light 11 is increased by the increased number of inspections. In order to prevent shortening as much as possible, preliminary inspection is performed at a lower steady level than the current for emergency lighting.

  As described above, if the inspection is performed more times than the number of inspections based on the predetermined rule, the abnormality can be detected with higher accuracy, but the life of the emergency light 11 is shortened. At the time of inspection, a current having a steady level lower than the current for emergency lighting is supplied to the emergency light 11, so that it is possible to detect an abnormality with higher accuracy without shortening the life of the emergency light 11.

  In the second embodiment, the emergency light lighting unit 15 makes the temporal change rate more gradual than the current for instantaneous emergency lighting according to the preliminary inspection lighting control signal, and sets the steady level more than the current for emergency lighting. The low power is configured to be supplied to the emergency light 11 in the same manner as the power consumption at the time of inspection based on a predetermined rule. The inspection time is not limited to such time, but at least Any time may be used as long as it can determine whether the secondary battery 12 is normal or abnormal. For example, even if the inspection time is shorter than that of the second embodiment, if a detection result that the capacity of the secondary battery 12 is extremely reduced is obtained, it can be determined that the secondary battery 12 is abnormal (defective). It is.

  In the first and second embodiments, the state of each emergency light lighting device 1 may be collected in the control panel 1.
