Abstract

Abstract: The national safety technical specifications and standards have clear provisions on the distance between the elevator car and the well wall facing the car entrance. Current measuring methods are lower measurement efficient and accuracy, and poor repeatability. With the increasing number of elevators, this traditional method is far from meeting the requirements of practical work. This paper studied on the Laser ranging technology applied to the distance measurement aiming to overcome those problems. The new measuring equipment was consisted of the laser ranging module, rotary encoder and Bluetooth module, which can measure and record all data related to the distance between the car and the car entrance shaft wall. The advantages of the new device are higher repeatability and reliability, which greatly improve the measurement efficiency. It is suitable for measuring the distance between elevator car and shaft well of high-rise building, thus the inspectors can be free from the heavy work of measurement.
