An emergency lighting device having timer means for starting is disclosed. In Patent Document 2, a disaster prevention lighting device is provided with a transmission / reception unit for performing monitoring / control from the outside and an inspection switch, and monitoring and control of emergency and normal operation of the disaster prevention lighting device are collectively performed by the control device. A lighting system for disaster prevention that has been performed is disclosed. Patent Document 3 discloses an emergency lighting device that includes a plurality of individual emergency lighting units, a central monitoring and control unit, and a communication system that connects them, and that can execute a periodic diagnosis process on time. Yes. Patent Document 4 discloses a guide lamp device that can automatically perform its own inspection every predetermined period by outputting an inspection start signal from the timer means every predetermined period and the inspection circuit starts the inspection. Has been. And an inspection means for inspecting the secondary battery by forcibly turning on the lamp for a predetermined inspection time by the lighting means, and a monitoring means for constantly monitoring one or more operation states including at least the charged state of the secondary battery. And an abnormality detection means for detecting the abnormality of the secondary battery and the lamp by comprehensively judging the inspection result by the inspection means and the monitoring result by the monitoring means (a lighting device that can improve the inspection accuracy of the secondary battery ( (Hereinafter referred to as “lighting device A”) has been proposed separately by the present applicant (see Japanese Patent Application No. 2002-279760).
[0006]
Further, in Patent Document 5, after storing the control data in the nonvolatile memory, the power from the commercial power supply is shut off, so that when the battery is abnormal, it is based on the control data stored in the nonvolatile memory. An electric device or the like that can be continuously controlled is disclosed. Similarly, in Patent Document 6, the battery life determination state determined by the battery determination unit (circuit) that normalizes the battery determination state when the battery is detached is shown as non-volatile as a storage unit. An emergency lighting device that stores data in a memory and stores the battery as normal when the battery is removed is disclosed.

Transistor) 36, and a switching unit 37 that switches and connects any one of the normal driving circuit unit 34 and the driving circuit unit 35 to the lamp 31, and also includes a power supply circuit unit 38 and a control unit 30.
[0021]
The power supply circuit unit 38 converts the AC power from the commercial power source AC into rectified and smoothed DC power and supplies the DC power to the charging circuit unit 33, the control unit 30, and the communication unit 4. .
[0022]
The control unit 30 includes, for example, a charge detection unit 301 that detects a charging current from the charging circuit unit 33 to the secondary battery 32 as a power failure occurrence detection unit of the commercial power supply AC, and a lamp from the drive circuit unit 35 as a lighting detection unit of the lamp 1. A lighting detection unit 302 that detects a current to 31; a voltage detection unit 303 that detects a voltage of the secondary battery 32 as an abnormality detection unit of the secondary battery 32; and a storage unit of a readable / writable nonvolatile memory such as an EEPROM 304 and a main control unit 300, which are operated by power from the secondary battery 32 via the power supply circuit unit 38 or the diode D. Note that the power failure occurrence detection means is not limited to the charge detection unit 301, and may be configured to detect the occurrence of a power failure of the commercial power source AC when the input voltage of the power supply circuit unit 38 drops below a predetermined voltage, for example.

In the emergency lighting process of the lamp 31, when the occurrence of a power failure of the commercial power supply AC is recognized from the detection result of the charge detection unit 301, the switch 36 is turned on and the drive circuit unit 35 is changed to the lamp 31 by the switching unit 37. By performing the switching connection, the process of performing the emergency lighting of the lamp 31 only with the power of the secondary battery 32 is executed. The details of this emergency lighting process will be described later.
[0025]
In the inspection process of the lamp 31, the inspection switch is turned on in accordance with an inspection instruction from the control device 1 in place of turning off the inspection switch (not shown) interposed between the commercial power supply AC and the normal drive circuit unit 34 and the power circuit unit 38. If the inspection result of the secondary battery 32 stored in advance in the storage unit 304 is normal as in the lighting device A, the switch 36 is turned on and the drive circuit unit 35 is switched to the lamp 31 by the switching unit 37. By switching connection, the lighting of the lamp 31 is attempted only with the power of the secondary battery 32, and the lamp 31 is checked for normality / abnormality based on the detection result of the lighting detection unit 302, and the result (S1) is transmitted to the communication unit 4. The process which transmits to the control apparatus 1 via is performed.

The normal / abnormal inspection of the secondary battery 32 is performed by measuring the time from the start of lighting of the lamp 31 after the inspection switch is turned off to the time when the detection result of the voltage detection unit 303 falls below a predetermined reference voltage. If the time is equal to or longer than the specified time, it is determined that the operation is normal.
[0027]
In the inspection state notification process, as a feature of the first embodiment, the inspection state (S2) for each inspection of the lamp 31 and the secondary battery 32 is limited to inspection state information having a high priority and is notified to the communication unit 4. Is executed. For example, the inspection status information is limited to four items of “inspection”, “charging”, “incomplete inspection”, and “inspection complete”.
[0028]
The inspection state information of “under inspection” is obtained when the lighting circuit unit 3 turns on the switch 36 according to the inspection command from the control device 1 and the switching unit 37 switches and connects the driving circuit unit 35 to the lamp 31. The state where the lamp 31 is lit only by the power of the secondary battery 32 is shown. The inspection state information “charging” indicates a state where the inspection is finished and the secondary battery 32 is charged by the charging circuit unit 33. The inspection status information of “inspection incomplete” indicates that the inspection was not completed due to a power failure or the like during the inspection. The inspection state information of “inspection completed” indicates a state in which the inspection is completed (the discharge of the specified time is finished) and the inspection result is output. The inspection state information may be transmitted and received between the lighting circuit unit 3 and the communication unit 4.
[0029]
When the inspection command is transmitted from the control device 1, the communication unit 4 receives the inspection command and transfers it to the main control unit 300 of the lighting circuit unit 3, as well as the inspection result and the inspection state from the lighting circuit unit 3. A process of transmitting information to the control device 1 is performed, and the apparatus is configured to operate with electric power from the power supply circuit unit 38. In addition, the communication unit 4 includes a CPU, a memory, and the like in order to execute processing according to various inspection state information.
[0030]
Next, an operation that characterizes the first embodiment will be described. First, the operation of the main control unit 300 when a power failure occurs will be described. When a power failure occurs (S10 in FIG. 2), processing for confirming whether or not the inspection is being performed is executed in step S11.
[0031]
If the inspection is in progress (Y in S11), the inspection is stopped, and in step S17, the switch 36 is turned on, and the switching circuit 37 switches the drive circuit unit 35 to the lamp 31 to connect the secondary battery 32. The process of performing the emergency lighting of the lamp 31 with only the power of Thereby, the lamp 31 is lit only by the power of the secondary battery 32. Thereafter, if power is restored (Y in S18), a process of notifying the communication unit 4 of inspection status information that has not been inspected is executed in step S19. Thereby, the communication unit 4 recognizes that the inspection state is incomplete inspection. However, in addition to the case of Y in S18 described above, the main control unit 300 is after power recovery in the case of Y in S21, Y in S24, and Y in S15, and the communication unit in step S30 of FIG. After the 4 is activated, the inspection state information is notified to the communication unit 4.
[0032]
If the inspection is not in progress (N in S11), a process for confirming whether or not the battery is being charged is executed in step S12.
[0033]
If charging is in progress (Y in S12), a process for emergency lighting of the lamp 31 with only the power of the secondary battery 32 is executed in step S20. Thereby, the lamp 31 is lit only by the power of the secondary battery 32. Thereafter, if power is restored (Y in S21), a process of notifying the communication unit 4 of the inspection state information during charging is executed in step S22. Thereby, the communication part 4 recognizes that the inspection state is charging.
[0034]
If the battery is not being charged (N in S12), a process for confirming whether or not the inspection is not completed is executed in Step S13.
[0035]
If the inspection is not completed (Y in S13), a process for emergency lighting of the lamp 31 with only the power of the secondary battery 32 is executed in step S23. Thereby, the lamp 31 is lit only by the power of the secondary battery 32. Thereafter, if the power is restored (Y in S24), a process of notifying the communication unit 4 of inspection status information that has not been inspected is executed in step S25. Thereby, the communication unit 4 recognizes that the inspection state is incomplete inspection.
[0036]
If the inspection is not completed (N in S13), a process for emergency lighting of the lamp 31 with only the power of the secondary battery 32 is executed in step S14. Thereby, the lamp 31 is lit only by the power of the secondary battery 32. Thereafter, if power is restored (Y in S15), a process of notifying the communication unit 4 of inspection status information of inspection completion is executed in step S16. Thereby, the communication part 4 recognizes that the inspection state is inspection completion.
[0037]
Next, the operation of the communication unit 4 after power recovery will be described. When the commercial power supply AC recovers (S30), the communication unit 4 is activated upon receiving power supply from the power supply circuit unit 38, receives inspection state information from the lighting circuit unit 3, and communicates with the control device 1 as appropriate. Processing is executed.
[0038]
That is, it is confirmed whether the inspection status information is inspection completion (S31). If the inspection status information is inspection completion (Y in S31), in step S35, the inspection completion mode, that is, the inspection command from the control device 1 is checked. A process of shifting to a constantly monitoring state that can be accepted is executed.
[0039]
If the inspection status information is not inspection complete (N in S31), it is checked whether the inspection status information is incomplete inspection (S32). If the inspection status information is incomplete inspection (Y in S32), in step S36 Then, the process shifts to an inspection incomplete inspection mode, and processing for transmitting information prompting re-inspection to the control device 1 is executed. After that, the control device 1 transmits the inspection command again.
[0040]
If the inspection state information is not incomplete inspection (N in S32), it is confirmed whether the inspection state information is being charged (S33). If the inspection state information is being charged (Y in S33), in step S37, (Return) Transition to the charging mode is performed, and processing for transmitting to the control device 1 information prompting not to issue an inspection command because charging is being performed.
[0041]
If it is not inspection state information during charging (N in S33), it is confirmed whether it is inspection state information during inspection (S34). If it is inspection state information during inspection (Y in S34), inspection is performed in step S38. The process of shifting to the middle mode and transmitting information indicating that the inspection is being performed to the control device 1 is executed. If it is not inspection state information during inspection (N in S34), the process returns to step S31, and the same processing is repeatedly executed.
[0042]
In the first embodiment, since the power supply circuit unit 38 that obtains predetermined DC power from the AC power of the commercial power source AC and supplies it to the communication unit 4 or the like is provided separately from the secondary battery 32, the control device 1 collectively Even when monitoring / control is performed, the emergency lighting time of the lamp 31 by the secondary battery 32 can be made longer than before.
[0043]
In addition, since the lighting circuit unit 3 is configured to limit the inspection state of each inspection of the lamp 31 and the secondary battery 32 to inspection state information having a high priority and notify the communication unit 4 of the inspection state, the internal wiring L2 The number of wires can be reduced. For example, in a case where each state of inspection, charging, inspection incomplete, and inspection completion is indicated by turning on / off a microcomputer port or a transistor, etc., there are 4 lines for transmitting the state information. Just a line. In this configuration, when both the charging and inspection completion lines are on and on, for example, it can be recognized that the charging is completed after the inspection, and the on and on changes to off and on. In this case, it is possible to recognize that the inspection is completed after the inspection is completed and the inspection instruction can be received from the control device 1.
[0044]
(Embodiment 2)
FIG. 4 is an operation flowchart of the illumination device according to the second embodiment of the present invention.
[0045]
The illumination device 2 of the second embodiment is characterized in that a timer function (inspection timer in FIG. 4) and a normal / abnormal determination function of the lighting circuit unit 3 are added to the communication unit 4 as a difference from the first embodiment.
[0046]
When the inspection command is received from the control device 1, the normality / abnormality determination function transmits the inspection command to the lighting circuit unit 3 as an inspection start signal. Depending on whether or not the inspection state information is being transmitted from the lighting circuit unit 3, It is confirmed whether or not the lighting circuit unit 3 has changed to a state under inspection, and if not changed, a process of transmitting an abnormality of the lighting circuit unit 3 to the control device 1 is executed. In addition, even if a predetermined time has elapsed from the time when the inspection start signal is transmitted to the lighting circuit unit 3, if the inspection state information indicating the completion of inspection is not transmitted from the lighting circuit unit 3 together with the inspection result information, the lighting circuit unit 3 A process of transmitting the abnormality to the control device 1 is executed. The predetermined time is set to be equal to or longer than the longest specified time used for the inspection process of the secondary battery 32, for example.
[0047]
Next, the operation of the normal / abnormal determination function of the communication unit 4 which is a feature of the second embodiment will be described. When an inspection command is received from the control device 1 (S40 in FIG. 4), an inspection start signal is transmitted to the lighting circuit unit 3 (S41), and it is confirmed in step S42 whether the lighting circuit unit 3 has changed to a state under inspection. Is executed.
[0048]
If the state does not change to the state being inspected (N in S42), a process of transmitting the abnormality of the lighting circuit unit 3 to the control device 1 is executed in step S47. Accordingly, the inspector on the control device 1 side can recognize that an abnormality has occurred in the illumination device 2 by receiving a notification to that effect from the control device 1.
[0049]
If the state changes to the state during inspection (Y in S42), the time is started by the inspection timer (S43), and in step S44, whether the inspection completion information during charging and the inspection state information during charging has been transmitted. The process of confirming is executed.
[0050]
If it has been transmitted (Y in S44), in step S48, (return) is shifted to the charging mode, and processing for transmitting information prompting the inspection command not to be issued because charging is being performed to the control device 1 is executed. The
[0051]
If it has not been transmitted (N in S44), in step S46, a process for confirming whether or not the elapsed time from the start of timing exceeds the predetermined time and the inspection timer is up is executed. If the inspection timer is not up (N in S46), the process returns to step S44, while if the inspection timer is up (Y in S46), a process of transmitting an abnormality of the lighting circuit unit 3 to the control device 1 is executed in step S50. Is done. As a result, the inspector on the control device 1 side can recognize that an abnormality has occurred in the lighting device 2.
[0052]
In the second embodiment, since the communication unit 4 determines whether the lighting circuit unit 3 is normal or abnormal, the control device 1 can also monitor the abnormality of the lighting circuit unit 3 collectively.
[0053]
(Embodiment 3)
FIG. 5 is an operation flowchart of the illumination device according to the third embodiment of the present invention.
[0054]
The illumination device 2 of the third embodiment is different from that of the second embodiment in part of the processing contents of the normal / abnormal determination function of the communication unit 4. That is, the normality / abnormality determination function according to the third embodiment receives information on the completion of inspection and inspection state during charging after receiving inspection state information during inspection from the lighting circuit unit 3, for example. When the inspection state information is received only when the inspection is completed, which is different from the schedule, the processing for transmitting the abnormality of the lighting circuit unit 3 to the control device 1 is executed.
[0055]
Next, the operation of the normal / abnormal determination function of the communication unit 4 which is a feature of the third embodiment will be described. In the third embodiment, steps S45 and S49 shown in FIG. 5 are different from those in the second embodiment, and thus the description of the same steps is omitted.
[0056]
If inspection state information during inspection completion and charging is not transmitted from the lighting circuit unit 3 (N in S44), processing for confirming whether inspection state information indicating only inspection completion is transmitted is executed in step S45. Is done.
[0057]
If inspection status information only for inspection completion is not transmitted, that is, if inspection is not possible (N in S45), the process proceeds to step S46, while if inspection status information only for inspection completion is transmitted, that is, during charging. If the inspection can be performed suddenly without shifting (Y in S45), a process of transmitting the abnormality of the lighting circuit unit 3 to the control device 1 is executed in step S49. As a result, the inspector on the control device 1 side can recognize that an abnormality has occurred in the lighting device 2.
[0058]
In Embodiment 3, since the abnormality of the lighting circuit unit 3 is monitored from a wider viewpoint by the communication unit 4, the abnormality of the lighting circuit unit 3 can be detected more suitably. For example, not only the components of the lighting device 2 but also the circuit abnormality of the lighting circuit unit 3 can be detected.
[0059]
(Embodiment 4)
FIG. 6 is an operation flowchart of the illumination device according to the fourth embodiment of the present invention.
[0060]
The illuminating device 2 of the fourth embodiment is substantially the same as the third embodiment, and performs (almost) the same processing as in FIG. 5 for each of a plurality of inspection modes having different inspection times as shown in FIG. Features.
[0061]
In the plurality of inspection modes of the fourth embodiment, for example, a periodic inspection mode that needs to be executed once every three months according to the provisions of the Fire Department or the Building Standard Law, and a relatively short cycle (for example, A mode for daily inspection that is executed once a week) is prepared. In the regular inspection mode, the secondary battery 32 is discharged for at least a specified time, whereas in the daily inspection mode, the secondary battery 32 is discharged for a shorter time (for example, about 1 minute).
[0062]
By the way, there are various models of the lighting device 2, and it is necessary to change the timer for managing the inspection time such as the specified time for each model, as well as the capacity of the secondary battery, the number of lamps and the lamps that are different for each model. It is necessary to design the lighting circuit unit 3 in accordance with the output. For this reason, in the fourth embodiment, in order to make the communication unit 4 common among the models, a periodic inspection timer having a different inspection time depending on the capacity of the secondary battery and the like is provided in the lighting circuit unit 3 for daily inspection. The timer is provided in the communication unit.
[0063]
Next, the operation of the normal / abnormal determination function of the communication unit 4 which is a feature of the fourth embodiment will be described. When an inspection command is received from the control device 1 (S40 in FIG. 6), an inspection start signal is transmitted to the lighting circuit unit 3 (S41), and it is confirmed in step S42 whether the lighting circuit unit 3 has changed to a state under inspection. Is executed.
[0064]
If the state does not change to the state being inspected (N in S42), a process of transmitting the abnormality of the lighting circuit unit 3 to the control device 1 is executed in step S47. As a result, the inspector on the control device 1 side can recognize that an abnormality has occurred in the lighting device 2.

If the state changes to a state during inspection (Y in S42), processing for determining the inspection type is executed in step S51. For example, if the control device 1 is configured so that information for determining the inspection type is transmitted together with the inspection instruction, the information indicates whether the inspection type is a mode for periodic inspections. It can be determined whether the mode.
[0066]
If the determined inspection type is the mode for periodic inspection, in step S52, a timer for periodic inspection is set (the maximum value of the periodical inspection time is set), and the same processing as in the third embodiment is executed. . S143 to S146 and S148 to S150 correspond to S43 to S46 and S48 to S50 in FIG. 5, respectively.
[0067]
If the determined inspection type is the mode for daily inspection, a timer for daily inspection is set (S53), and steps S243 to S246 and S248 to S250 are substantially the same as S43 to S46 and S48 to S50 in FIG. move on. The difference is that when the lighting circuit unit 3 is inspecting and the timer for daily inspection is timed up (Y in S246), in step S250, the mode is changed to (return) charging, and an inspection command is issued because charging is in progress. A process of transmitting information prompting the user not to send the information to the control device 1 is executed.
[0068]
In the fourth embodiment, an abnormality of the lighting device 2 can be suitably found by various inspections, and the communication unit 4 can be shared.
