ELEVATOR ELECTRICITY FEEDBACK DEVICE, ELEVATOR ELECTRICITY FEEDBACK METHOD AND ELEVATOR THEREOF
First Claim
1. An elevator electricity feedback device comprising a sampling unit, a transmitting unit and a central processing unit (CPU), whereinthe sampling unit electrically connected to an energy supply network of an elevator and the CPU, samples alternating current (AC) signals of the energy supply network and inputs the sampled AC signals to the CPU;
- the transmitting unit is electrically connected to a motor driver of the elevator, and through an AC resistor, electrically connected to the energy supply network, wherein when the motor driver is in an energy consuming state, the transmitting unit transmits an energy provided by the energy supply network to the motor driver, and when the motor driver is in an energy generating state, the transmitting unit feeds back an energy produced by the motor driver to the energy supply network; and
the CPU electrically connected with the transmitting unit, inputs the AC signals obtained by the sampling unit to the transmitting unit.
