Doppler radar-based adaptive automatic door system and control method thereof

Abstract

The invention discloses a Doppler radar-based adaptive automatic door system. The system is a Doppler radar-based adaptive automatic door system with low cost, can automatically adapt to the speed of pedestrians, and reduces time wastes and unhappiness caused by door opening waiting of the pedestrians; the system can avoid false door opening for a static target, and allows the door to be opened through a hand-operated opening button arranged at the entry of the door if a person stops behind the door and then wants to get in; a friendly human-machine interaction system is arranged, so the automatic door system is convenient for a user to flexibly set; an electric control self-locking mechanism is arranged in an executing mechanism part, and the self-locking mechanism can separate the door from the execution mechanism when the door cannot be automatically opened due to faults occur in the system execution mechanism through operating the human-machine interaction or the hand-operated opening button by a super user in order to rapidly open the door under the action of manpower; and a clamp proofing function is increased, so the safety of access pedestrians is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an adaptive automatic door system based on Doppler radar and a control method thereof. Background technique [0002] With the development of detection technology and the continuous improvement of user needs, automatic door systems have been widely used in some public places such as shopping malls and office buildings, bringing a lot of convenience to people's travel. The detection technology used mainly includes infrared induction and microwave radar detection technology. The automatic door using infrared sensing technology, as long as an object enters the sensing area, the door will automatically open and close after the set time is extended. The intelligence is extremely low, especially static objects will also trigger the door opening action. The automatic door system using microwave radar detection technology, when a moving target approaches the detection area, the...

AI Technical Summary

Problems solved by technology

[0003] However, most of the current automatic door systems have the following problems: lack of flexibility, adjusting the door opening response time and door opening speed without considering the speed of approaching the target, especially the mismatch with the speed of pedestrians entering and exiting, causing pedestrians to wait anxiously or dissatisfied; man-machine The interaction is not perfect, and the user cannot flexibly set the interaction according to the actual application scenario; when the actuator for automatically opening and closing the door fails, the system cannot control the opening of the door through the electronic device. Once a fire or other disaster occurs, the door cannot be opened immediately. Life and property pose a great danger; most automatic door systems and access control systems cannot be well integrated, and cannot take into account the flexibility of the automatic door system and the security of the access control system
