In order to operate even during a power failure, a storage battery 9 is provided in the site of a building (not shown).

  The storage battery 9 is connected to a charger 8 that is charged from the three-phase AC commercial power supply 1 and an inverter 18 that converts the DC power output from the storage battery 9 into a three-phase AC power supply. Power is supplied to the elevator control panel 4 via the power switching panel 3 that switches the supply source from the three-phase AC commercial power source 1 to the storage battery 9.

  Next, the monitoring device 23 detects an abnormal state of the equipment and reports the abnormality to a monitoring center (not shown) that is remotely connected via a communication line, and inputs and outputs signals to and from the equipment. An input / output device 16 to be performed, a control device 15 that detects a change in an input signal of the input / output device 16 and controls the monitoring device 23 with a built-in predetermined program; When the power recovery information is acquired via the input / output device 16, a power switching command signal for selectively switching the power supply destination to the three-phase AC commercial power source 1 or the storage battery 9 is output to the power switching board 3. Illumination lighting pattern memory that is provided in the power failure detection unit 14 and the storage device 19 connected to the control device 15 and stores in advance a plurality of lighting patterns to be described later for the in-car illumination 13 according to the elapsed time from the power failure. Part 0, when the control device 15 acquires the power failure information and power recovery information of the power receiving panel 2 via the input / output device 16, it has passed since the power failure detection unit 14 detected the power failure using an internal clock (not shown). It is comprised with the power failure time measurement part 21 which measures time and outputs the illumination pattern switching command signal which selectively switches the illumination pattern to the in-car illumination 13.

  In addition, the in-car lighting 13 and the common unit lighting 22 are supplied with the single-phase AC commercial power supply 10 through the distribution board 11 and the single-phase power switching board 12, and the in-car lighting 13 through the elevator control board 4. In addition, power is supplied to the common unit illumination 22.

  Further, the inverter 18 supplies power to the in-car lighting 13 and the common unit lighting 22 via the single-phase power switching board 12 that switches the power supply source from the single-phase AC commercial power supply 10 to the storage battery 9 when a power failure occurs. .

  Next, in FIG. 4, a car 6 has a plurality of LED lights 13 </ b> A installed on the ceiling board 45 and covered with a shielding board 46 in the car interior light 13, thereby making point light emission and surface light emission of the LED light 13 </ b> A. .

  Further, as shown in the LED lighting pattern T1, the LED lighting 13A is set to the lighting state 13Aa when 100% is lit, and the lighting state 13Aa and the extinguishing state 13Ab when 50% is lit as shown in the LED lighting pattern T2. As shown in the LED lighting pattern T3, when the light is 25%, three times the lighting state 13Aa is set to the light-off state 13Ab. Such LED lighting pattern is an illumination lighting pattern storage unit in the storage device 19 of the monitoring device 23. 20 is stored in advance.

  Next, the operation of this embodiment will be described with reference to FIGS.

  First, the power failure detection unit 14 of the monitoring device 23 monitors the power receiving panel 2 via the control device 15 and the input / output device 16 to detect a power failure of the three-phase AC commercial power supply 1 (step S1), and a power failure detection unit. When 14 does not detect a power failure, the elevator normally travels (step S2).

  When the power failure detection unit 14 detects the occurrence of a power failure in the power receiving panel 2 in step S1, the control device 15 confirms the operation status of the elevator with respect to the elevator control panel 4 via the input / output device 16 (step S3). When a power failure occurs while the elevator is running, the rescue operation device 17 is activated during a power failure, stops the car 6 to the nearest floor, opens the door 47, and rescues the passengers trapped in the car 6. Rescue operation during power failure (step S4). Here, when the running elevator stops power, the car stops on the spot, the in-car light 13 is turned off, a non-illustrated power-off lamp supplied with a battery (not shown) provided in the car 6 is turned on, and a power failure occurs. Wait for the activation of the emergency rescue operation device 17. Here, a blackout lamp (not shown) is lit for a predetermined time with a predetermined illuminance when the power supply to the elevator is cut off, and is required to be installed by the Building Standard Law.

  Next, when the car 6 arrives at the nearest floor and stops (step S5), or when a power failure occurs while the elevator is stopped in step S3, the control device 15 passes through the input / output device 16. The power supply switching board 3 and the single-phase power supply switching board 12 are operated to switch the power supply of the elevator control board 4 and the car interior lighting 13 and the common section lighting 22 to the storage battery 9 and the inverter 18 (step S7).

  After switching the power supply to the storage battery 9, the control device 15 confirms whether the elevator is stopped or whether there is a landing call or car call (step S8). If there is no landing call or car call in the elevator stop state, the car 15 The inner illumination 13 is turned off (step S9), the process returns to step S8, and waits until a hall call or a car call is generated.

  When the occurrence of the hall call is detected in step S8, the power failure time measurement unit 21 selects the LED lighting pattern T2 from the lighting lighting pattern storage unit 20, and the lighting so that the car lighting 13 is turned on by 50%. The pattern switching command signal is output to the control device 15, and the control device 15 controls the LED illumination 13A with the illumination pattern switching command signal (step S10) and outputs an elevator travel command (step S11).

  Next, the power failure time measuring unit 21 counts the elapsed time from the occurrence of the power failure, determines within 2 hours (step S12), and if within 2 hours, continues the 50% lighting of the LED lighting pattern T2, and the elevator Is stopped (step S13), and the car illumination 13 is turned off when the elevator stops (step S14).

  Next, the power failure detection unit 14 acquires whether or not the commercial power supply has recovered via the control device 15 and the input / output device 16 by monitoring the power receiving panel 2 (step S15). Return to S1.

  If the power failure continues at step S15, the process returns to step S8.

  Next, when the elapsed time from the occurrence of a power failure exceeds 2 hours in step S12, the power failure time measuring unit 21 determines that the elapsed time from the occurrence of a power failure is within 4 hours (step S16) and within 4 hours. For example, the LED lighting pattern T3 is selected from the lighting lighting pattern storage unit 20, and the control device 15 controls the LED lighting 13A so that the car lighting 13 is turned on by 25% (step S17), and the process returns to step S13.

  If it is determined in step S16 that the elapsed time since the occurrence of the power failure has exceeded 4 hours, the control device 15 turns off the in-car lighting 13 and turns on a power failure (not shown) provided in the car 6 ( Step S18), confirm that there is no elevator landing or car call (step S19), if there is a call, run the elevator (step S20), return to step S19, if there is no call in step S19, The elevator is stopped (step S21), and the stopped state is maintained until power is restored.

  According to the present embodiment, the LED illumination 13A, which is the in-car illumination 13, is reduced by the elapsed time after the occurrence of a power failure, so that the power consumption of the storage battery 9 for the elevator facility can be suppressed. .

  Moreover, since the LED lighting 13A is reduced in the car 6 along with the elapsed time of the power failure, the remaining amount of the storage battery 9 can be roughly grasped, so that the resident can quickly prepare for the power failure response. .

Further, in this embodiment, the LED lighting 13A is reduced by the elapsed time from the occurrence of the power failure, but the LED lighting 13A is changed according to the cumulative value of the elevator traveling time from the occurrence of the power failure and the numerical value obtained by measuring the remaining capacity of the storage battery 9. The same effect can be obtained even if the light is reduced. Further, according to the present embodiment, when the elapsed time of the power failure exceeds a predetermined time, the LED of the LED illumination 13A is turned off by the control device 15 of the monitoring device 23, and the power failure lamp (not shown) is turned on. The power consumption of the storage battery 9 can be suppressed, and the lighting in the car 6 at the time of a power failure can be extended for a relatively long time. Thereby, this embodiment can extend the operation | movement of the building equipment containing an elevator, and can ensure the convenience with respect to a resident.

  Further, in the present embodiment, it has been described that the LED lighting 13A of the elevator car 6 is reduced. However, even if the common unit illumination 22 is reduced, the same effect can be obtained.

  In the present embodiment, the lighting pattern of the LED lighting 13A has been described in three types: 100% lighting of the LED lighting pattern T1, 50% lighting of the LED lighting pattern T2, and 25% lighting of the LED lighting pattern T3. It is clear that the number of types of lighting patterns may be increased or decreased depending on the size of the car 6, the capacity of the storage battery 9, and the like.
