Abstract

The invention discloses an elevator system. The elevator system comprises a power board, a driver board, a main control board, a brake circuit, interface boards and a safety circuit with a plurality of safety switches, wherein the power board is used for being connected to a mains supply alternating current, and converting the mains supply alternating current to provide corresponding working powersupply for the safety circuit, the brake circuit, a door machine, the main control board and the interface boards. The driver board is used for driving a motor to operate by controlling a power switch in a frequency inverter under the control over the main control board, and realizing the start and stop, phase order protection, phase failure protection and overvoltage and undervoltage protectionof the motor are realized by controlling the state of the power switch under the control over the main control board. The multiple safety switches are correspondingly connected to the interface boards, and the interface boards disconnect an operating contactor from a holding brake contactor in the brake circuit when any of the safety switches is abnormal. The dependence of the elevator system on electrical connection can be alleviated, the use of low voltage electrical elements is reduced, and the size of a control cabinet for device stacking is reduced.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator system. Background technique [0002] In the existing elevator system, a control transformer is usually used to connect to the mains, and then converted into 24V safety loop power supply, 24V DC current, 110V brake power supply and 220V door machine power supply through various conversion circuits. Sometimes there is a situation that the capacity of the control transformer is not enough, and in the case of different brake voltages, frequent replacement of materials is required. Moreover, in the existing elevator system, there are many low-voltage electrical components in the actuator, which increases the volume of the control cabinet. For example, contactors that control the start and stop of motors, phase sequence relays, etc., among which the noise of contactor pull-in has always been an unsolvable problem in the industry. [0003] In addition, the current elevator system...
