Abstract

The invention discloses a lift controller comprising a lift main loop and an lift main control board which are connected through a control circuit. The lift main loop comprises a rectification loop, adirect current bus loop and an inversion loop which are connected in sequence. A current sensor is installed on the direct current bus loop, and the current sensor is connected with the lift main control board through the control circuit. The running states including the temperature and the current of the lift controller can be detected and the running speed of the lift can be automatically adjusted according to the timely state so that the lift traction machine and the controller are prevented from running under the condition of high temperature and high load for a long time, faults are reduced, the service life of the lift is prolonged and the lift controller is particularly suitable for the plateau environment.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to an elevator controller, an elevator and a control method. Background technique [0002] The traditional elevator controls the motor through the feedback signal of the motor encoder, and at the same time records the height information of each position switch in the hoistway by means of pulse counting, so as to realize accurate leveling and direct parking. Under normal conditions, the drive control system relies on shaft data to drive the traction machine at a speed of: start-acceleration section-constant speed section-deceleration section-stop, and the speed control will not change due to changes in the external driving environment. In some special cases, such as the plateau environment, due to the elevation of the altitude, the change of air pressure and temperature has a great impact on the operation of the elevator traction machine, and the equipment is damaged quickly and the s...
