Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of electric door anti-climbing, in particular to an intelligent infrared anti-climbing device for electric doors. Background Art
[0002] Electric doors are doors that are driven by a motor to automatically open and close the door body. The most common type of electric retractable door is the electric retractable door at the entrance and exit of public places. It is mainly composed of a retractable door body, a head, a track and a control system. The door body is made of multi-section retractable materials. The motor in the head drives the door body to retract and open. It has the advantages of small space occupation and large extension length. The door body length can be flexibly adjusted according to the actual site and needs.
[0003] As an important access control facility, electric retractable doors primarily restrict unauthorized access to specific areas. However, due to their relatively short construction, people often attempt to climb over them, posing a potential safety hazard. Therefore, electric retractable doors are often equipped with anti-climbing devices consisting of infrared sensors. Using infrared technology, infrared sensors are installed above the electric retractable door or near the track. When someone attempts to climb over the retractable door, the human body blocks the infrared light, triggering the sensor and immediately sounding an alarm.
[0004] However, in practice, people have noticed that environmental factors have a greater impact on infrared rays. In rainy, snowy or foggy weather, snowflakes or raindrops may block or scatter the propagation path of infrared rays, causing false alarms. The most important thing is that the infrared sensor is limited by the angle, and the infrared emission angle is certain. As the electric telescopic door moves, the landing point of the infrared ray on the reflector will also change, and the reflection angle will also change, causing the receiver to be unable to receive the reflected infrared ray, resulting in false alarms.
