Elevator resetting system

Abstract

The invention discloses an elevator resetting system. The elevator resetting system comprises an elevator controller, an intermediate level signal device triggered when a lift car locates at a level and an absolute position triggering device triggered when the lift car locates between levels, wherein the positions above and below the absolute position triggering device are respectively provided with at least one intermediate level signal devices in the direction of the lift car movement, the absolute position triggering device outputs a reference signal after being triggered by the lift car, the intermediate level signal device adjacent to the absolute position triggering device in the direction of the lift car movement outputs a leveling signal after triggered by the lift car, the elevator controller receives the reference signal and the leveling signal, and the floor position of the lift car when the level signal device is triggered is obtained according to the floor position of theabsolute position triggering device sending the reference signal. According to the elevator resetting system, the elevator reset running time of he elevator resetting system can be shortened, and thesystem complexity and the arrangement cost are reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator reset system for higher floors. Background technique [0002] The existing technology generally confirms the position of the elevator car through the host rotary encoder and the floor photoelectric signal. When the elevator car is lost due to emergency stop, wire rope slippage, photoelectric and forced reduction switch signal errors and other reasons during the use of the elevator , the elevator needs to perform position confirmation operation. [0003] At present, the most common reset operation mode is to make the elevator run to the end station and initialize the starting point of the position. [0004] There are also some technologies to realize the absolute position recognition of elevators. For example, the patent document with the publication number CN202046769U uses infrared equipment to encode each floor of the elevator shaft. This technology undoubtedly i...

Another example is the patent document whose publication number is CN102951508B, using the method of weighing and weighing the compensation chain at the bottom of the car to realize absolute position monitoring. problem, the accuracy requirement is not high

[0005] In general, in the prior art, the lost position of the elevator is usually reset at the end station, and the reset time is long; or the position of the elevator is confirmed by monitoring the code of each floor, the installation and debugging workload is large, and the absolute encoder installed on the speed limiter makes the system Increased costs
