Embodiment Construction
[0014] Refer to the following figure 1 and figure 2 One embodiment of the elevator control device according to the present invention will be described.
[0015] Such as figure 1 As shown, the elevator control device according to this embodiment has an inverter 2 for converting the AC voltage of the commercial power supply 1 into a DC voltage, a capacitor 3 for smoothing the output voltage of the inverter 2, and smoothing the output voltage through the capacitor 3 . A PWM inverter 4 that converts the direct current voltage into a variable-frequency and variable-voltage AC voltage, a motor 5 that is driven by receiving power from the PWM inverter 4, a pulley 6 that rotates under the drive of the motor 5, and is wound on the pulley The elevator car 7 and the counterweight 8 connected by the main sling 6a on the 6. The PWM inverter 4 drives the motor 5 under the control of instructions from the elevator control circuit 9 to raise and lower the elevator car 7 .

PROBLEM TO BE SOLVED: To provide an elevator control device, capable of maintaining a floor display function of a hall control device even in a standby mode simply and at a low cost.SOLUTION: A power supply circuit connecting a control power source 10 and a car control device 11 to each other is provided with a power shutdown means 16. When an elevator control circuit 9 determines that the operation mode of an elevator device is switched to a standby mode, the power shutdown means 16 is switched to the OFF state according to a command signal from the elevator control circuit 9, and cuts off the power supply from the control power source 10 to the car control device 11. Thus, a ceiling light in a car 7 is extinguished and a car internal console panel 14 is also put in the operation disabled state. Thus, the power consumption in the standby mode can be held down. Before switching to the standby mode, it is determined whether someone stays in the car 7 according to an output signal of a load detecting means 13 to secure the safety of a user.
Description
technical field [0001] The invention relates to an elevator control device, in particular to a technology for reducing standby power. Background technique [0002] In the prior art, in order to reduce unnecessary power consumption during standby and to easily return to the normal operation mode in response to the operation of the hall button, for example, a control device for an elevator is proposed in Patent Document 1. The control device has a hallway device including a microcomputer, an elevator control panel including a CPU, a transmission channel for information communication between the hallway device and the elevator control panel, a circuit breaker for turning on / off the hallway power supply under the control of the CPU, and an elevator control panel in the hallway. A backup power supply that supplies a backup voltage when the power supply is disconnected, a button backup circuit that supplies a backup voltage to the elevator control panel when the hall button is ON ...
