Abstract

The invention discloses a high-speed elevator operating parameter monitoring method based on kinetic analysis, and belongs to the field of elevator lift car safety control systems. The high-speed elevator operating parameter monitoring method based on kinetic analysis is realized by the following technical scheme that (1) a vibration acceleration sensor is installed in an elevator lift car, vibration signals are collected and remotely transmitted to a CPU, and a vibration displacement diagram is obtained through integral preliminary calculation; (2) a tension detection device is installed on load bearing beam of an elevator, and a tension unbalance coefficient B of an elevator traction steel wire rope is calculated according to a formula (1); (3) an elevator balance coefficient Kping is calculated; (4) the braking distance of a brake is measured; and (5) a noise sensor is arranged in an elevator lift car and used for collecting noise signals. By detecting a series of parameters relatedto vibration and noise of the elevator lift car and monitoring and evaluating real-time operating characteristics of the elevator lift car, a decision and a guarantee are provided for safe operationof the high-speed elevator.

Description
