Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] Existing laser sensors for revolving doors can only be installed at high places and detect from top to bottom. Fully protected, and in the complex scene where the revolving door contains multiple door leaves and are installed side by side, the door leaves can both rotate and translate. The two door leaves will be very close together, almost overlapping, and the existing laser sensor will cause false alarms due to detection of adjacent door leaves.

Abstract

The invention relates to the technical field of laser ranging, and discloses a laser anti-collision method and system for a multi-door-leaf revolving door, electronic equipment and a storage medium. The method comprises the steps that ranging data, obtained based on a laser sensor, between door leaves and a target object and the running state of the door leaves are obtained, the number of the door leaves is at least two, and the running state of the door leaf comprises a translation state and a rotation state; data processing is conducted on the distance measurement data to obtain distance measurement data after data processing, the distance measurement data after data processing including a target object shape; and whether the door leaf is controlled to stop running or not is judged according to the corresponding running state of the door leaf and the corresponding distance measurement data after data processing. The multiple laser sensors are installed at the bottoms of the front face and the back face of the door leaf, no blind area exists in a detection area, interference on the laser sensors is effectively filtered, and false alarm is avoided.

Description

technical field [0001] The invention relates to the technical field of laser ranging, in particular to a laser anti-collision method, system, electronic equipment and storage medium for a revolving door with multiple doors. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of modern buildings, people's demand for automation and intelligence of modern buildings continues to increase. As an automation technology product, automatic revolving doors are increasingly used in theaters, banks, large supermarkets, In the entrances and passages of modern buildings such as hotels. [0003] The automatic revolving door is currently the most technically demanding type among all automatic door categories. It has a gorgeous appearance and good sealing function, but there are safety problems that cannot be ignored. Automatic revolving door injuries have occurred many times, bringing national economic loss and personal injury. ...
