Embodiment Construction

[0023] Hereinafter, an embodiment as an example of the present invention will be described with appropriate reference to the drawings. figure 1 An example of the schematic configuration of the entire elevator operation control system in the embodiment of the present invention is shown. The car 102 is accommodated in a car frame not shown in the figure, and the car frame installed at one end of the main cable 104 travels in the hoistway (not shown) by the traction machine 106. The traction machine 106 has a The motor of the power source for elevator travel and the sheave on which the main rope is wound. A balance weight 108 is suspended from the other end of the main cable. The motor of the hoisting machine 106 and the brakes 110a and 110b for braking the rotation of the hoisting machine 106 are controlled by the elevator control device 112, and the car 102 is driven to stop at the arrival floor. From the viewpoint of the safety of elevator operation, a plurality of brakes ar...

Abstract

The present invention provides an elevator operation control system and a method thereof. A slippage operation state in which a tractor rotates and a cage is caused to operate at a state that a brake for braking the tractor performs braking even in a mode that is not used for stopping the cage is detected, and an abnormity detection signal is output. Hereon, an emergency stopping is performed forthe cage, and a position detector determines a stopping position of the cage. The data which represent the current position of the cage are compared with the position data of each arrival storey, which are stored by a storage device. Based on the result, the arrival storey which is most close to the emergency stopping position of the cage is determined in each arrival layer. Based on the determined result, a re-operation direction of the cage is determined irrelevantly with the operation direction before the emergency stopping.

Description

technical field [0001] The invention relates to an elevator operation control system and method. Background technique [0002] In the elevator system, due to unpredictable reasons, although it is not in the mode of stopping the car, an abnormal state in which the hoisting machine rotates and the car is moved while the brake is braking the hoisting machine may occur. That is, a slipping driving state. When a slipping state is detected, the car will be brought to an emergency stop for safety. When it is determined that there is no problem even if the car that has been stopped in an emergency is restarted, in the conventional elevator operation control system, the car is made to travel in the direction in which it was traveling before the emergency stop. [0003] However, such an operation control method has problems from the viewpoint of making the car in the slipping state reach the arrival floor as quickly as possible. This is because, in the direction in which the car tr...
