Light curtain imaging method and system, recognition method and system, light curtain device and elevator equipment

Abstract

The invention discloses a light curtain imaging method and system, identification method and system, light curtain device and elevator equipment. The light curtain imaging method includes: drawing the light curtain at a set time according to the data received by each receiving part of the light curtain Each pixel unit in the light curtain frame can indicate whether the receiving part has received data; the light curtain frames set at multiple time points are sequentially spliced ​​to form a light curtain image. The light curtain imaging method and system, light curtain device and elevator equipment proposed by the present invention can image passing objects through the scanning of the light curtain, provide basic data for subsequent object judgment, and provide technical support for the light curtain Internet of Things. The identification method and system proposed by the present invention can identify the objects (including objects and passengers) entering and exiting the elevator, and expand the function of the light curtain device.

Description

technical field [0001] The invention belongs to the technical field of light curtain equipment and relates to an elevator light curtain, in particular to a light curtain imaging method and system, an identification method and system, a light curtain device and elevator equipment. Background technique [0002] Elevator is the most commonly used vertical transportation vehicle in modern high-rise buildings. It saves people's time and physical strength and provides convenience for daily life. As a special equipment that is closely related to the safety of public life, the safe operation of elevators has attracted more and more attention from the society. However, due to the complex structure of the elevator, it is an urgent need for elevator management, maintenance and safe operation to ensure the safe and reliable operation of the elevator and to detect its operating status and fault conditions. [0003] In order to improve the safety of the elevator, the elevator needs to be...

Problems solved by technology

[0005] In addition, existing elevator equipment recognizes objects entering and exiting the elevator, usually through manual viewing through cameras. There is no solution that can automatically recognize the shape of objects, and the intelligence of elevator equipment needs to be further improved.

[0006] It can be seen that the current light curtain technology is only used to detect the existence of objects, and cannot identify passing objects, which greatly limits the role of light curtains.
