Description

  The present invention relates to an emergency lighting automatic inspection system that turns on a lamp with an emergency power source such as a secondary battery when a normal power source such as a guide light or an emergency light fails.

  Conventionally, an emergency lighting device such as a guide light or an emergency light is used to turn on (emergency lighting) a lamp with an emergency power source including a secondary battery in the event of a power failure due to a fire or an earthquake. It is required by the Fire and Disaster Management Agency Notification and the Building Standards Law to regularly check whether emergency lighting is performed normally.

  Usually, an emergency lighting device is provided with a switch for forcibly stopping the power supply from the utility power supply (commercial power supply) to the lamp to make a pseudo power outage. By operating the drawstring that is hanging down and turning on the switch, the lamp is turned on by supplying power from the secondary battery on a regular basis (for example, once every three months, hereinafter referred to as “periodic inspection”). Inspection to turn on (inspection of whether or not emergency lighting by the secondary battery is normally performed) is performed. Here, according to the provisions of the Fire and Disaster Management Agency and the Building Standard Law, the lamps are effectively lit up for 20 minutes or 60 minutes in the case of guide lights and 30 minutes in the case of emergency lights by supplying power from the secondary battery. Normally, the inspector must hang a weight on the drawstring, turn on the switch, and monitor whether the lamp can be effectively lit within the specified time. . Moreover, in general, guide lights and emergency lights are installed at multiple locations in the building, so it is necessary to look around each of the lighting devices one by one, which is very time-consuming for the inspector. It was work. For this reason, various automatic inspection systems for reducing the burden on the inspector in the inspection of the lighting fixture have been proposed.

As an inspection method for such a lighting device, as disclosed in Patent Document 1, the control unit of the lighting device comprehensively detects abnormalities in secondary batteries and lamps from detection results of a charge value, a voltage value, and a lighting time. In addition to periodic inspections, a determination unit is provided to constantly monitor the state of the secondary battery, and the determination unit comprehensively determines the inspection results and monitoring results of the periodic inspection to check for secondary battery and lamp abnormalities. the judgment to Rukoto not only conventional statutory routine inspection results as, overall judgment together with the monitoring result of the constantly as to improve the inspection accuracy of the secondary battery is known.

  However, in such an emergency lighting automatic inspection system, especially when it is used as a light source even during regular use as emergency lighting, naturally the number of times the lamp blinks and the cumulative lighting time are accumulated at a frequency similar to that of regular equipment. In the inspection of the lamp, judgment is made based on the lamp current that flows through the lamp when the lamp is turned on and off. In the inspection of the secondary battery, the charging current of the secondary battery flows in a closed loop via the lamp filament. A lamp abnormality can be detected by the presence or absence of this charging current. For this reason, when it is determined that there is an abnormality at the time of inspection, it is after the filament has already broken and the charging current has stopped flowing. In this state, the lamp is turned on in the event of a power failure or emergency, which is the purpose of emergency lighting. There was a problem that it could not be made. Further, in such an automatic inspection system, since the secondary battery is discharged every time inspection is performed, battery consumption increases as the number of inspections increases, and there is a possibility that deterioration of the battery is likely to be promoted by inspection. .

As another emergency lighting automatic inspection system, as shown in Patent Document 2, a lamp for disaster prevention, an emergency secondary battery, and a lamp from a commercial power source are always turned on, and in case of an emergency such as a power failure Equipped with a lighting device that turns on the lamp from the secondary battery, and a transmission / reception unit for external monitoring and control, and monitoring and control of emergency and normal operation of one or more disaster prevention lighting devices having inspection switches By sending a signal for automatic inspection from the control device that performs collectively, it discriminates between automatic inspection work and emergency situation, saving power to output no-voltage contact output to the control side in emergency situation, Those that reduce the consumption of secondary batteries are known. However, as described above, since battery consumption associated with the number of inspections in automatic inspection is not taken into consideration, there is a possibility that deterioration of the battery is likely to be promoted by inspection.
JP 2004-119151 A Japanese Patent Laid-Open No. 08-180980

  The present invention has been made to solve the above-described problem, and determines the end of the lamp life (before the lamp has run out) based on the number of blinks of the lighting fixture and the cumulative lighting time, thereby deteriorating the lamp. By estimating the state, the inspection schedule can be automatically changed in advance to reduce the frequency of self-inspection other than legal periodic inspections and lengthen the inspection cycle according to the deterioration state and life of the lamp. This provides an emergency lighting automatic inspection system that can reduce the deterioration of secondary battery life due to lamp inspection, increase the probability of emergency lamp lighting, and ensure that emergency lamps can be lit in an emergency. The purpose is to do.

In order to achieve the above object, the invention of claim 1 is directed to an illumination load, a regular block for lighting the lighting load with a commercial power source during normal operation, and an emergency use for lighting the lighting load in an emergency when no power is supplied from the commercial power source. A lighting device having a block, an emergency power source for supplying power to the emergency block, and an inspection unit for inspecting the lighting device by automatically and periodically operating the emergency block. in emergency lighting automatic inspection system, comprising a storage unit for storing the cumulative number of blinks and the accumulated lighting time of the lighting fixture, the inspection unit includes a control unit that controls lighting of the luminaire, stored in said storage means Determining means for determining the lamp life based on the lamp life prediction of the lamp based on the cumulative number of flashing times and the cumulative lighting time of the lamp. For example, the control means, when the lamp life of the luminaire is determined to have been degraded by the determination unit, and changes the inspection schedule of the emergency block to longer than originally inspection period.

According to the invention of claim 1, since the inspection unit changes the inspection schedule of the emergency block based on the number of blinks of the lighting fixture and the cumulative lighting time, for example, the lighting load, that is, the deterioration state of the lamp is estimated. The frequency of voluntary inspections other than the regular periodic inspections can be reduced, and this can prevent the life of the emergency power supply (secondary battery) from being deteriorated due to lamp inspections, and ensure that the emergency lights are turned on in an emergency. it can. In addition, the emergency lighting that is turned on during normal use can be turned off constantly, and the user can be actively prompted to replace the lamp, which is an illumination load. In addition, it is possible to appropriately replace the luminaire by estimating the degree of lamp deterioration that is the illumination load.

  Hereinafter, an emergency lighting automatic inspection system according to a first embodiment of the present invention will be described with reference to FIG. In FIG. 1, an emergency lighting automatic inspection system 10 includes a lighting apparatus 1 (referred to as a slave unit) to be inspected, and a control device 20 (main unit) connected to the plurality of lighting apparatuses 1 and communication lines 14 to manage the entire system. Call). The control device 20 includes an inspection unit 21 that inspects and controls the luminaire 1, and the inspection unit 21 controls the inspection of each luminaire 1, the number of blinks of each luminaire 1, and the cumulative lighting time number. And a main storage unit 23 (storage means) for storing inspection information including the number of lamp replacements and the consumption state of the secondary battery 4. The main control unit 22 includes a microcomputer, and the main storage unit 23 includes a nonvolatile memory such as an EEPROM. In addition, the control device 20 includes a communication unit that exchanges data with the lighting fixture 1 via the communication line 14. Since this communication means can be realized by a conventionally known technique, detailed description thereof is omitted.

  The luminaire 1 is supplied with power from lamps 5a and 5b (lighting loads) composed of a light source such as an incandescent lamp and a discharge lamp, a regular block 2 for lighting the lamp 5a during normal operation by the commercial power supply 7, and a commercial power supply 7. Between the emergency block 3 that lights the lamp 5b (lighting load) in an emergency that is not performed, the secondary battery 4 (emergency power supply) that supplies power to the emergency block 3, and the inspection unit 21 of the control device 20 Inspecting the luminaire 1 with a control signal from the inspection unit 21 connected with the communication unit 8 for transmitting / receiving inspection information, the communication unit 8 with the signal line 12, and connected with the emergency block 3 with the signal line 13. Part 9. Further, a change-over switch 6 for cutting off the power supply of the commercial power supply 7 to the regular block 2 is provided.

  The regular block 2 is powered only from the commercial power supply 7 to turn on the lamp 5a and is turned off in an emergency. The emergency block 3 is supplied with power from the commercial power supply 7 during normal use, and is supplied with power from the secondary battery in the event of an emergency such as a power failure, and the lamp 5b is always lit. The regular block 2 and the emergency block 3 are controlled by a control signal from the inspection unit 21, and control units 2a and 3a that control the respective blocks, and storage units 2b and 3b that store inspection data and control data of each block, It has lighting parts 2c and 3c that turn on the lamps 5a and 5b in accordance with control signals from the control parts 2a and 3a. Moreover, the control part 3a transmits the control signal 11 based on the command from the inspection unit 21, interrupts the changeover switch 6, and cuts off the power supply to the regular block 2 from the commercial power source 7. As a result, a pseudo power failure state is created, and the power supply to the regular block is stopped, whereby the lamp 5a is turned off. The controller 3a recognizes the power failure, switches the commercial power supply 7 of the lamp 5b of the emergency block 3 to the secondary battery 4, and continues to light the lamp 5b as an emergency light.

  By the way, as explained in the prior art, the inspection (inspection of whether or not the emergency lighting by the secondary battery 4 is normally performed) required by the Fire and Disaster Management Agency Notification and the Building Standards Law is periodically performed (for example, 3 months). It is necessary to carry out periodic inspection once a day. In the emergency lighting automatic inspection system 10, the blinking state of the lamp and the voltage of the secondary battery during regular use are constantly monitored, and the monitoring data is stored in the main storage unit 23 and the storage units 2 b and 3 b of each block. . Therefore, this monitoring data is used in the periodic inspection. First, when the periodic inspection is started by an instruction from the inspection unit, the changeover switch 6 is cut off, the power supply from the commercial power supply 7 to the service block 2 is stopped, and a pseudo power failure state is forced. When the control unit 3a of the emergency block 3 detects this power failure state, power is supplied from the secondary battery and the emergency lamp 5b is turned on. Necessary inspections including the inspection of the secondary battery 4, the inspection of the lamp by measuring the lamp current, and the cumulative lighting time are performed. Then, considering the inspection data up to now, the inspection unit 21 determines whether the secondary battery is normal or abnormal, and stores these inspection results in the main storage unit 23. Send a message to indicate that something is wrong and complete the regular inspection.

  In this emergency lighting automatic inspection system 10, in addition to the periodic inspection described above, periodic periodic inspection, that is, function maintenance inspection by lamp discharge for a short period of time being carried out other than legal inspection (herein referred to as voluntary inspection). ) And early detection of abnormalities in lighting fixtures. In this periodic periodic inspection of the lighting fixture 1, normally, when power is supplied from the commercial power source 7 (always), the changeover switch 6 is turned off by the control signal 11 from the control unit 3a at the time of inspection. The commercial power supply 7 to the block 2 is cut off, and power is supplied to the emergency block by the secondary battery 4. Then, in accordance with an inspection command from the inspection unit 21 via the communication unit 8, the inspection unit 9 inspects the interior of the luminaire 1, and stores various inspection data including the number of times the luminaire is blinked and accumulated, and the number of lamp replacements. While storing in the memory | storage part 3b in the lighting fixture 1, it transmits to the inspection unit 21 of the main controller 20, and the transmitted inspection data are memorize | stored in the main memory part 23.

  The emergency block 3 is a block for supplying power from the secondary battery in order to turn on the lamp 5b in an emergency in which power is not supplied from the outside due to a power failure or the like. In order to confirm this, power is supplied from the secondary battery 4 to the emergency block 3. At the time of inspection such as periodic inspection, the power source of the lighting unit 3 c is automatically switched from the commercial power source 7 to the secondary battery 4, and the lamp 5 b is driven by the secondary battery 4. Therefore, when an inspection command for self-inspection comes from the inspection unit 21, the emergency block 3 automatically switches from the commercial power source 7 to the secondary battery 4 as in the case of a power failure, and the secondary battery 4 is consumed. . Further, at the time of inspection, the changeover switch 6 is turned off by the control signal 11 from the control unit 3a of the emergency block 3, and the power supply to the service block 2 is cut off, whereby the power supply to the lamp 5a is cut off. .

  The inspection unit 21 can sequentially or arbitrarily instruct the at least one or more lighting fixtures 1 via the communication line 14. Then, in response to this inspection instruction, a command is sent to the inspection unit 9 of each luminaire 1 to constantly monitor and automatically collect inspection data and store it in the main storage unit 23. And based on the data, such as the frequency | count of blinking of the lighting fixture memorize | stored and cumulative lighting time, the lifetime of a lamp is estimated and a self-inspection schedule is changed.

  The causes of lamp life can be broadly divided into a decrease in luminous flux due to phosphor deterioration due to an increase in the cumulative lighting time, and a scattering and deterioration of the emitter of the lamp filament with the increase in the number of flashes (which ultimately leads to disconnection). Conceivable. Therefore, if the data on the number of blinking lamps and the cumulative lighting time can be examined and the lamp life can be predicted, control is performed to perform the minimum necessary inspection for each lighting fixture according to the prediction level. Can do. Thereby, the fall of a lamp life and the deterioration of a secondary battery can be suppressed.

  On the other hand, in the emergency lighting automatic inspection system of the present embodiment, the power failure is detected when the commercial power is turned off at any time or in an emergency, and this data is stored in the storage units 2b and 3b and the main storage unit 23 of each block 2 and 3, respectively. I remember it. Therefore, with this power failure detection function, when the power on / off by the wall switch is regarded as a power failure, and the number of times of on / off detection is counted, the number of on / off times by the wall switch can be directly counted as the number of times the lamp blinks. In addition, the automatic inspection system 10 is also lit in an emergency state during a periodic inspection according to the periodic inspection schedule and a self-inspection performed according to the self-inspection schedule. The number of inspections (number of lamp flashes) at this time is also recognized by the inspection unit 21 of the control device 20, and summed with the counts of the number of times of periodic inspections and voluntary inspections, and recorded as the total number of times the appliance flashes. is doing. Thereby, the total number of blinks can be easily obtained from the daily detection signal. Further, the lighting time from when the power is turned on until a power failure is detected is counted by an RTC (real time clock) of the control device 20 (master unit). Thereby, the cumulative lighting time can also be known.

  As described above, in the inspection system of the present embodiment, for the inspection of the luminaire 1, the number of blinks and the cumulative lighting time that particularly affect the lamp life are not usually provided without means for detecting them. Based on the monitoring data results obtained by the monitoring operation, inspection control during normal use can be performed.

  Here, this inspection control will be described. First, the relationship between the lamp life and the number of blinks will be described. As described above, the life of the lamp decreases with an increase in the number of times the lamp flashes. However, in the example of a fluorescent lamp, since the scattering of the emitter due to one flashing is severe, the lamp life is generally reduced once. It is known that the life is shortened by about 30 minutes to 90 minutes every time it blinks. For this reason, considering that the rated life of an efficient Hf lamp (High-frequency Inverter Lighting Fixtures: high-frequency lighting dedicated fluorescent lamp) is about 12,000 hours, the number of lamp life blinking times is 8 , 4,000 to 24,000 times. However, since the lamp life is also affected by the starting voltage, power supply voltage fluctuation, ambient temperature, frequency of blinking per unit time, etc., the lamp life blinking frequency is estimated to be a little less than 8 as the lamp life blinking frequency. , 000 times. Therefore, as shown in FIG. 2, when it is determined that the cumulative number of blinks is 8,000 or more, which is the lamp life blink number, the function maintenance inspection by the short-term lamp discharge is performed in addition to the legal inspection ( Here, the period of self-inspection is changed to, for example, twice the current schedule period (when the number of blinks reaches 8,000) and three times (when the number of blinks reaches 10,000). As a result, the inspection unit 21 changes the inspection schedule so as to minimize inspections involving blinking of lamps other than legal inspections.

  Furthermore, when the luminaire is continuously energized, the lifetime of the lamp is reduced due to the continuous energization. Therefore, it is necessary to consider degradation due to continuous energization in addition to the degradation of the lifetime due to the number of blinks. A description will be given of the life prediction of the lamp in consideration of this continuous energization. First, in continuous energization, the luminous flux of the lamp changes with time, and as shown in FIG. 3, exhibits a luminous flux decay characteristic that decreases with the cumulative lighting time.

Here, when a level compared with this light speed decay characteristic curve, for example, the cumulative lighting time exceeds 6,000 hours, the cumulative lighting time is regarded as a factor for promoting the deterioration of the lamp life, and the cumulative lighting time is set as the blinking time. Using this conversion table in Table 1 below, this converted flashing time is added to the current cumulative flashing time. In this manner, by adding the converted number of blinks to the current cumulative number of blinks, the life deterioration due to both the cumulative number of blinks and the cumulative lighting time is integrally determined using the total number of blinks. Based on the total number of flashes, it is possible to predict the life of the lamp closer to the actual, so that the control of the self-inspection cycle can be optimized.

The inspection cycle control of the self-inspection according to the present embodiment based on the lamp life prediction taking the accumulated lighting time into account will be described with reference to the flowchart of FIG. Here, assuming that the lamp life is 8,000 times and the cumulative lighting time is 6,000 hours or more, for example, when the cumulative lighting time is 6,000 hours, the cumulative lighting time is set as the lamp life. Consider the case of adding to degradation estimation data. First, when performing a voluntary inspection, perform the inspection schedule to optimize the inspection schedule. When the inspection schedule setting work is started by a command from the inspection unit 21, the main control unit 22 of the inspection unit 21 sets the legal periodic inspection schedule in the main storage unit 23 in the inspection unit 21 (S1), and the self-inspection. The initial standard cycle of the schedule (cycle earlier than the periodic inspection) is set (S2), and the number of blinks K of the lamp expected life is set to 8,000 times and stored (S3). The number of blinks Ka stored in the storage unit 3b of the block 3 is read (S4). The read cumulative blink count Ka is sent to the inspection unit 21 via the communication unit 8 and stored in the main storage unit 23. Similarly, the cumulative lighting time T stored in the storage unit 3b is read according to a command from the inspection unit 21 (S5). If the cumulative lighting time T is 6,000 hours or longer (NO in S6), The inspection unit 21 uses the conversion table of Table 1 to convert the cumulative lighting time T to the number of flashes to be added corresponding to the cumulative lighting time T, and obtains the converted flashing number Kb (S7). If the cumulative lighting time T is less than 6,000 hours (YES in S6), the converted blink count Kb is set to 0 (S8). The calculated conversion flashing number Kb is added to the previously determined cumulative flashing number Ka (S9) by the inspection unit 21 (S9), and the total total flashing number K (K = Ka + Kb) is used to determine the lamp life. Therefore, it is compared with the number of blinks 8,000 times of the lamp life prediction (S10).

  If the total number of blinks K is less than 8,000 (YES in S10), it is determined that the life is still relatively long, and the inspection cycle is performed according to the original schedule (S11). In the case of NO in S10, if the number of blinks K is 8,000 times or more and less than 10,000 times (YES in S12), it is judged that the life has deteriorated slightly, and other than regular inspection of laws and regulations The self-inspection period that is being carried out is set to be approximately twice as long as the standard period of the initial setting (S13), and the setting is completed (S17). As a result, the life of the lamp can be prolonged, and at the same time, the power consumption of the secondary battery can be suppressed, and battery deterioration can be reduced. If the number of blinks K is 10,000 times or more (NO in S12) and the number of blinks K is less than 12,000 (YES in S14), the self-inspection cycle is set to about three times longer than the standard. (S15), the inspection unit 21 is controlled to change the inspection schedule so as to minimize the inspection with blinking of the lamp other than the regular periodic inspection, and the setting is completed (S17). Furthermore, if the frequency of blinking increases, for example, if the number of blinks K is greater than 12,000 (NO in S14), the self-inspection schedule other than the statutory periodic inspection is deleted for the appliance, and other than periodic inspection The control is performed so that the periodic inspection is not performed (S16), and the setting is completed (S17). In any case, after completing the setting (S17), the self-inspection is started (S18). This change in the self-checking period prevents the lamp life from deteriorating and suppresses the consumption of the secondary battery, so that the emergency light can be reliably turned on in an emergency, and the lighting of the emergency is reliable. Can increase the sex.

  Thus, by converting the cumulative lighting time T into the number of flashes and adding it to the cumulative number of flashes, the life of the lamp can be determined by the total of the cumulative number of flashes and the cumulative lighting time, so it is more accurate and reliable. The lamp life can be predicted, and the period of the periodic inspection schedule in accordance with the lamp life prediction can be suitably increased. Thus, it is possible to control the lamp of the luminaire 1 whose lifetime is predicted so as not to blink as much as possible. Thereby, the deterioration of the secondary battery accompanying the inspection work can be suppressed, and the battery life can be extended. Therefore, it is possible to take necessary measures before the lamp burns out by predicting the lamp life in advance, and it is possible to reliably turn on the emergency light in an emergency, thereby improving the reliability of the emergency lighting equipment. it can.

  Next, an emergency lighting automatic inspection system according to a second embodiment of the present invention will be described. Since the configuration of the emergency lighting automatic inspection system in the present embodiment is the same as that in the first embodiment, the illustration is omitted. In the present embodiment, the main control unit 22 (control unit) of the inspection unit 21 further includes a control function for controlling the lighting of the lighting fixture 1, and the main control unit 22 is stored in the main storage unit 23 (storage unit). The lighting schedule is changed based on the number of blinks of the lighting fixture 1 and the cumulative lighting time. That is, according to the number of times the lamp blinks and the cumulative lighting time, if the number of lamp blinks exceeds a predetermined number, for example, 8,000 times, and the appliance has not been replaced once, the inspection unit No. 21 is the end of the lamp life, and in order to prevent further deterioration of the lamp for the luminaire 1, no emergency inspection other than the statutory periodic inspection is performed, and the emergency lighting that should originally be lit during normal use The constant lighting itself is not performed.

  With reference to the flowchart of FIG. 5, lighting control in the emergency lighting automatic inspection system of the present embodiment will be described. First, when performing a self-inspection, a lighting schedule is set for optimizing the inspection schedule. When the lighting schedule setting operation is started by a command from the inspection unit 21, the main control unit 22 of the inspection unit 21 sets the lighting schedule for legal periodic inspection in the main storage unit 23 in the inspection unit 21 (S1), The initial setting of the lighting schedule for the self-inspection is performed (S2), and the number K of blinks of the predicted lamp life is set and stored (S3), and the inspection unit of the emergency block 3 of the lighting fixture 1 is stored. 9 is used to read the cumulative blink count K stored in the storage unit 3b (S4). The read cumulative blink count K is sent to the inspection unit 21 via the communication unit 8 and compared with the lamp life blink count (K = 8,000) set in the inspection unit 21 (S5). . Then, the flashing number data obtained according to the cumulative flashing number and the cumulative lighting time is read from the storage unit 3b, and when the flashing number K is 8,000 times or more (YES in S5), and the lamp replacement number N If it is zero (YES in S6), only the statutory periodic inspection is turned on (S7), and further, the lighting of the emergency lighting that is turned on even during normal use is stopped (S8), and the process ends (S9). If the number of blinks K is less than 8,000 times in S5, and if the number of lamp replacements is one or more times in S6, the lighting schedule for self-inspection is set as originally determined that there is little deterioration in lamp life ( S10) After completing the setting (S11), the self-inspection is started (S12).

  As described above, when the number of lamp blinks exceeds a predetermined number of times, for example, 8,000 times, and the lamp has not been replaced, it is determined that the lamp life is at the end, and the lamp is determined to be lit. Therefore, the lamp can be prevented from further deterioration by not performing any inspection other than the regular periodic inspection for the appliance. In addition, the emergency illumination lamp 5b that should originally be turned on during normal use can be urged to actively exchange the lamp by intentionally turning it off during normal use.

  Next, an emergency lighting automatic inspection system according to a third embodiment of the present invention will be described. Since the configuration of the emergency lighting automatic inspection system in this embodiment is the same as that in the first embodiment, the illustration is omitted. In the emergency lighting automatic inspection system of the present embodiment, the main control unit 22 (determination means) of the inspection unit 21 further has a determination function for determining abnormality of the lighting fixture 1 based on the number of blinks of the lighting fixture 1 and the cumulative lighting time. I have. That is, the inspection unit 21 comprehensively determines from the lamp replacement timing and the number of blinks of each lighting fixture 1 (slave unit) connected to the control device 20, and there is a fixture with a significantly higher number of lamp replacements than other fixtures. If it is determined that there is a lamp, it is determined that the appliance is abnormal rather than a lamp abnormality.

In the first embodiment described above, the relationship between the number of lamp blinks and the lamp life is 8,000 to 24,000 times by simple calculation. This is because the lighting circuit for lighting the lamp properly preheats according to the lamp design information. This is the level when the current and starting voltage are designed. Therefore, if the lighting fixtures (particularly lighting circuits etc.) are out of the standard, the lamp life will be greatly affected. Here, as a condition that the lighting fixture itself is considered incomplete,
(A) Lamp life blinking frequency: There is already a lamp with a life of less than 8,000 times, or
(B) Among all the lighting fixtures connected to the control device 20, there is a lamp replacement history, and among the number L of a plurality of lighting fixtures that are normally lit, the number of lamp replacements is the same and the number is the largest. There is a lighting fixture in which the number of lamp replacements (N times) of a certain lighting fixture is more than three times the number of replacements (M times) (N / M ≧ 3).
Either of these can be considered.

The deficiencies of the lighting fixture will be described with reference to Table 2 below. Table 2 shows the current inspection state of the lamps of each lighting fixture. For example, it is the lighting fixture C that has a lamp blinking frequency of 8,000 or less at the present time and the lamp has an abnormality. The lamp of this luminaire C has an abnormally early failure compared to the case where the standard lamp life is 8,000 times. In this case, since the life of the lamp should be longer, it is determined that there is an abnormality in the appliance that lights the lamp, not the cause of the lamp. Thereby, since this lamp corresponds to the condition (a), it is a replacement target. In addition, among the six lighting fixtures whose lamps are normally lit, the number of lamp replacements is one (M = 1) most, while only the lighting fixture E is three times (N = 3). We are exchanging. This corresponds to the condition (b), and the number of lamp replacements in the lighting fixture E is too large compared to the other, so that it is determined that the lighting fixture is deficient than the lamp, and is subject to fixture replacement. As described above, it is possible to determine the appliance abnormality (ordinary block abnormality) from the lamp blinking number and the total lighting time obtained from the cumulative lighting time and the lamp replacement number. Thereby, both conditions are always monitored as the determination conditions for replacing the appliance, and it is determined that there is an abnormality in the lighting apparatus 1 that satisfies the above condition (a) or (b). Can be informed and exchanged.

  Next, the inspection control of the inspection system will be described with reference to the flowchart of FIG. In the same manner as described above, the lamp life is predicted to be 8,000 times. First, the inspection work is started by a command from the inspection unit 21 of the control device 20. Steps S1 to S4 are the same as those in the flowchart of FIG. When the total number of flashing times obtained according to the cumulative number of flashes read from the storage unit 3b and the cumulative lighting time is less than 8,000 times (YES in S5), and the lamp replacement number N is not zero. In this case (NO in S6), since the lamp has been replaced even though the number of blinks has not reached 8,000 times of the lamp life, the main control unit 22 of the inspection unit 21 determines that there is an abnormality on the appliance side. Then, an appliance replacement message is transmitted (S8), and the process ends (S12). In the case of YES in S6, it is determined that there is no problem with the lamp life and the equipment, and the self-inspection is performed as scheduled (S7). If the number of blinks K is greater than 8,000 (NO in S5), the inspection unit 21 compares the number of lamp replacements of all the luminaires connected to the control device 20, and most of them. A large number of identical replacements M is selected (S9) and compared with all replacements N of lamps of any appliance connected to the control device 20. If N / M ≧ 3 is satisfied (YES in S10), the inspection unit 21 judges that the compared appliance is abnormal, sends a message for replacing the lighting fixture 1 (S8), and ends (S12). If N / M ≧ 3 is not satisfied (NO in S10), it is determined that both the lamp and the instrument are normal, the self-inspection is set according to the schedule (S11), the setting is finished (S12), and the self-inspection is performed.

  According to the emergency lighting automatic inspection system 10 according to the above-described various embodiments, the end of life of the lamps 5a and 5b (before the lamp burns out) is predicted based on the number of blinks and the cumulative lighting time of the lighting fixture 1, and the lamp 5a 5b can be estimated. Thereby, according to the deterioration state of lamp | ramp 5a, 5b, an inspection schedule can be changed and the inspection frequency of voluntary inspections other than a legal regular inspection can be dropped. By reducing the inspection frequency and extending the inspection cycle, the life of the lamps 5a and 5b can be maintained, and the life of the emergency secondary battery 4 accompanying the lamp inspection can be prevented from being reduced. Lighting can be performed reliably, and the reliability of emergency lighting can be improved. At the same time, it is possible to save labor for the inspection work by omitting the trouble of the inspection person measuring the inspection time and the trouble of operating the inspection switches of the emergency lighting fixtures scattered in the building.
