Safety sensing technology for automatic doors is a vital part of the automatic door system, which ensures the safety and reliability of the door during use. This technology is mainly implemented through various sensors and control systems, which can detect the presence of pedestrians or obstacles, thereby avoiding accidents such as pinching or hitting pedestrians.
The most common safety sensing technologies include infrared sensing, microwave radar sensing, and ultrasonic sensing. These technologies can monitor environmental changes around the door in real time and transmit information to the control system of the automatic door so that timely responses can be made.
Infrared sensing technology uses infrared sensors to detect the activities of people or objects. When a person or object enters the sensing area, the sensor will detect and send a signal, and the controller will open the door lock after receiving the signal to allow people to pass. When a person or object leaves the sensing area, the sensor will send a signal again, and the controller will immediately close the door lock to ensure safety and energy saving.
Microwave radar sensing technology detects the activities of people or objects by emitting microwave signals and receiving reflected signals. This technology has higher sensitivity and accuracy, and can detect more subtle changes in movement, thereby providing higher security.
Ultrasonic sensing technology uses ultrasonic sensors to detect the activities of people or objects. It determines whether there are obstacles or pedestrians around the door by emitting ultrasonic signals and receiving reflected signals. This technology is highly adaptable to the environment and can provide stable and reliable sensing effects in various complex environments.
In addition to the above-mentioned common safety sensing technologies, some advanced sensing technologies such as lidar and face recognition are also used in automatic door systems. These technologies can provide more accurate and efficient sensing effects, further improving the safety and user experience of automatic doors.
In general, the safety sensing technology of automatic doors is an important part of ensuring the safety and reliability of doors during use. With the development of science and technology and the continuous improvement of people's safety requirements, the safety sensing technology of automatic doors is also constantly innovating and developing to meet the safety needs in different scenarios.
