ABSTRACT:
A controlling apparatus is provided to control an electric elevator in a more efficient manner. The controlling apparatus includes a motor controller for controlling the rotation of a driving motor of the elevator; a position detector for determining the current position of a cab and for generating a cab position signal; a load detector for determining the weight load of the cab and for generating a first weight load signal; cab calling means for generating a cab calling signal in response to the selection made on the cab calling means by a person or perople waiting to take the cab to arrive at a floor which they intend to go; cab status indicating means for indicating the current position, running direction and weight load of the cab; and system controlling means, coupled to the motor controller, the position detector, the load detector, the cab calling means and the cab status indicating means, for receiving the cab position signal from the position detector, the first weight load signal from the load detector, and the cab calling signal from the cab calling weight load generating one of a plurality of second weight load signals in accordance with the first weight load signal, for actuating the cab status indicating means to display the current position, running direction and weight load of the cab in accordance with the cab position signal and the one second weight load signal, and for enabling the motor controller to actuate the driving motor of the electric elevator in accordance with the cab calling signal.
