Abstract
In the elevator apparatus, the brake control unit transmits and receives a signal between the first and second brake control operation units, a brake control sharing memory unit storing shared data of the first and second brake control operation units, and a hoisting control communication unit. It has a brake control communication unit. The first and second brake control calculators compare the input signal and the calculation result with each other via the brake control shared memory unit, and output a failure detection signal from the brake control communication unit when the comparison result exceeds a predetermined range.
Description
BACKGROUND OF THE
In general, the safety system of an elevator is constituted by a safety chain which is a series circuit including a plurality of switches and a plurality of contacts. Among these contacts and switches, for example, an overspeed governor or a limit switch is operated according to the operation of the car. In addition, the switch and the locking device of the landing door are operated in accordance with the movement of the door.
In contrast, in an elevator using a conventional electronic safety system, various sensors, contacts and switches are monitored by an electronic safety bus by a central controller. Each bus node is connected to a sensor, a contactor, and a switch at each position. Status information is then sent from the bus node to the central controller. In addition, the central controller is provided with a microprocessor board having an input / output port connected to a safety bus and a bus node (see
On the other hand, in the conventional brake control apparatus of an elevator, the hoisting machine brake is operated by the first brake control unit at the time of abnormality detection, and the car is emergency stopped. In addition, when the deceleration of the car reaches a predetermined value or more during the emergency braking operation of the hoisting brake, the braking force of the hoisting brake is reduced by the second brake control unit (see

And a hoisting control control unit for transmitting and receiving signals, a brake control unit including: a first brake control calculating unit for performing an operation for controlling the brake device based on a signal corresponding to the first speed detector, and a second A second brake control calculating section for performing calculations for controlling the brake device based on a signal corresponding to the speed detector, a brake control sharing memory section for storing shared data of the first and second brake control calculating sections, a hoisting control communication section, Brake control communication unit for transmitting and receiving signals between , The first and second braking control computing unit outputs a fault detection signal exceeds the box and, at the same time, the comparison results in predetermined range of each other, comparing the input signal and the operation result through the braking control shared memory from the brake control communication.
