TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator shaft dynamic safety monitoring, and particularly relates to an elevator shaft three-dimensional scanning reconstruction and deformation dynamic monitoring system. BACKGROUND

[0002] The elevator operation environment of domestic high-rise buildings is relatively poor, and the narrow space in the elevator shaft makes it very difficult to detect and repair the entire system of the elevator mechanism. At the same time, the use of key components of the elevator is not easy to be monitored in real time, and the casualties caused by elevator failures still occur frequently, which seriously affects the safety of people, so real-time monitoring of the operation state of the elevator has become an important topic of modern development.

[0003] In the existing elevator shaft dynamic monitoring technology, the traditional elevator shaft wall ranging technology is complex to operate, inconvenient to carry, and has limitations in monitoring. Although the binocular vision technology has high precision, it needs a high-precision positioning system, which is difficult to implement and expensive. The virtual simulation technology can only analyze ideal conditions and cannot be applied to actual shafts. The above existing monitoring methods all have corresponding deficiencies.

[0004] Therefore, it is necessary to design an elevator shaft three-dimensional scanning reconstruction and deformation dynamic monitoring system to solve the problems existing in the existing dynamic monitoring equipment. SUMMARY

By adopting a three-dimensional scanning system composed of upper and lower three-dimensional scanners, real-time reconstruction of the three-dimensional data model of the elevator shaft is realized. By adopting a deformation monitoring system of vibration sensors, dynamic monitoring of the deformation of the elevator guide rail is realized. By adopting a rotational speed sensor installed at the output port of the traction machine, the running speed of the elevator is measured.
