Omnidirectional computer vision-based safe and energy-saving control device for pedestrian automatic door

Abstract

The invention discloses an omnidirectional computer vision-based safe and energy-saving control device for a pedestrian automatic door. The control device comprises an omnidirectional vision sensor (ODVS) without dead corners, a microprocessor, a controller, a voice player and an automatic door, wherein the omnidirectional vision sensor is used for acquiring the video information of a full view around the automatic door and is provided with a network interface; the microprocessor is used for detecting the status of the automatic door and the behaviors of pedestrians; the controller is used for controlling the automatic door to be opened or closed or rotated; the voice player is used for performing a safety prompt; the automatic door is used for the pedestrians at the opening position of a building to pass; the ODVS is connected with the microprocessor through the network; the microprocessor is connected with the controller; the controller is used for controlling the action of an automatic door motor; the voice player is connected with the microprocessor through a voice interface; and the ODVS is arranged in the middle of the top part of the automatic door. The omnidirectional computer vision-based safe and energy-saving control device for the pedestrian automatic door automatically controls the automatic door to be opened through analyzing the behaviors of the pedestrians according to the behavioral intentions of the pedestrians. According to the behaviors of the pedestrians and the status of the automatic door, the safety accident that the pedestrians are rolled by the automatic door is avoided, and the goal that the safety control, the energy saving property control and the comfort control of the automatic door are highly fused is achieved.

Description

Technical field [0001] The invention belongs to the application of omnidirectional vision sensor, digital image processing, automatic control and other technologies in the safety, energy saving and comfort of pedestrian automatic doors. Background technique [0002] Pedestrian automatic doors include sliding, flat opening, folding, rotating and other forms. Automatic doors are widely used in the entrances and exits of office buildings, storefronts, banks, hotels, etc. because of their convenience, beautiful appearance, and energy-saving advantages. They are mainly used for the passage of people at the opening of the building. According to the function of the revolving door, the opening position of the revolving door can realize the permission and prohibition of personnel entry and exit. The realization process adopts a mechanical method. Although various safety measures have been adopted in the design, processing, installation and use of revolving door products, there are still ...
