is open. The car is operated by a control circuit 13,
When reaching the time of landing on the floor, the door openable section detection condition contact group 2 is activated, and the door openable section detection relay 3 is energized. This makes it possible to open and close the door, and the door opens by the operation of the door opening/closing circuit 14. Since these operations are well known, detailed explanation will be omitted.

The power failure rescue completion relay 10 is energized by the circuit 1t-11a-13-1j-(E-), and is self-maintained through the circuit 10a-8c by closing the contact 10a. This means that a power outage rescue operation command has been issued. Then, the contacts 10b and toc are closed.

Therefore, since the door open completion memory relay 5 is deenergized and the contact 5b is open, the door close standby memory relay 8 is deenergized and the contacts 8d and 8e are closed.

), the automatic landing circuit 13 in the event of a power outage is activated and rescue operation is started. When the car reaches the door opening/closing area of the nearest floor, the contact group 2 closes, the door opening/closing area detecting relay 3 is energized, and the contact 3b opens. Therefore, the automatic floor landing circuit 13 becomes drop-on (inoperable) during power outage, and the car stops within the door opening/closing area. The door is then opened by the operation of the door opening/closing circuit 14. When the door opening is completed, the door opening completion detection contact group 4 is closed. Since the contact 3a is closed, the door opening completion memory relay 5 is energized and self-maintains by closing the contact 5a. Further, the contact 5b is closed. After the non-interference time has passed (the time relay is not shown), the door opening/closing circuit 14 operates again and the door closes. 0 When the door is closed, the door closing switch 6 closes (E+) -1i-10b-5

全放電することはない。8e is opened, so door opening/closing circuit 141 door opening/closing area detection relay 3. The control circuit 121, the door opening completion memory relay 5, and the automatic floor landing circuit 13 during a power outage are disconnected from the storage battery power sources E+ and E-, and the discharge current of the storage battery is limited. On the other hand, the time relay 9 is energized by the closing of the contact 8b, and operates after a certain period of time, and the contact 9a is opened. At this time, the contact 8C is open, so the power failure rescue termination relay 10 is deenergized, and the contact 9a is opened. 10b and 10c are open. As a result, the door close standby memory relay 8 and the time limit relay 9 are deenergized. This completes the power outage rescue operation, and the discharge current of the storage battery becomes zero. Therefore, by providing the relay 11, the discharge current of the storage battery becomes the same after the rescue operation, so even if there is a power outage for a long time, the storage battery will not be completely discharged.

なっている。Relays 1 and 10 used in the above device are ordinary relays, and relay 11 generally has a capacitor and a resistor connected in parallel to the relay coil, so that when the relay coil is de-energized, the capacitor stores the A device is used that obtains a time limit until recovery by discharging the accumulated charge at a predetermined time constant (determined by the capacitor capacity, resistor, and coil resistance). However, in general, relays are
It operates when the coil voltage is 70 to 80% or more of the rated voltage, and is 10 to 20% of the rated voltage (hereinafter this value is referred to as v).

When it drops, relay 11 drops on, so the time from relay 1 drop-on to relay 11 drop-on is T (

時間が数秒以上になることもあり、特定できない）。[Problem to be solved by the invention] However, the power supply system of a building in which an elevator is installed is usually equipped with a phase advance capacitor for improving the power factor, and loads such as pump motors of air conditioning equipment are connected to the power supply system. If this were the case, due to its influence and the impedance of the power company's power transmission system, the fall of the power supply voltage during a power outage would not be as steep as shown in Figure 5 (sometimes the fall time would be several seconds or more). (There are some cases, but it cannot be specified.)

、価格が高くなるという問題があった。In such a case, the relay 1 is dropped on when the power supply voltage falls below VaO. However, when the relay 1 is in the operating state, the contacts 1a and 1b are closed in FIG. The drop-on of relay 11 and the drop-on of relay 11 occur simultaneously. (If VDO varies due to variations in relays, relay 11 may drop on before relay 1.) Therefore, when contacts 1i and lj close in Fig. 3,
Since the contact 11a is open, the relay 10 is not energized,
There was a problem that rescue operations would no longer be possible. On the other hand, this problem can be solved by using a special voltage detection relay (which operates at a predetermined voltage drop) as the power failure detection relay, but this poses the problem of increased cost.
