Description

TECHNICAL FIELD

[0002] Elevator flat layer refers to when car approaches the stop station, the action of making car sill and landing sill reach the same plane. It can also be understood as the slow motion process of elevator when it normally stops at the landing. When the elevator car runs to the landing according to the inside or outside instruction and enters the flat layer area, the flat layer measuring device or sensor must first determine whether the elevator car is in the appropriate position in the landing, so that the car sill and the landing sill reach the same plane. At present, the collection of elevator flat layer state and the determination of car position mainly adopt magnetic induction technology or light induction technology. The magnetic induction technology is easily disturbed by external electric field and magnetic field, and has the problems of low measurement accuracy and being easily affected by the displacement of measurement equipment. The light induction sensor has a relatively high requirement for the cleanliness of the environment, and the installation process of the light induction sensor is complex and has high installation requirements.
