How does the safety light curtain ensure the safety performance of automatic doors

In modern society, Automatic Gate is an important facility to improve the convenience, beauty and safety of buildings, and is widely used in various public places. However, with the increase in traffic and the diversification of traffic needs, the safety performance of Automatic Gate has become an issue that cannot be ignored. In order to ensure the absolute safety of people when entering and exiting automatic doors, the innovative technology of safety light curtain came into being and became an invisible shield to protect the safety performance of automatic doors.

The basic principle of safety light curtain
The safety light curtain is a device that uses infrared or laser technology to achieve safety protection. It consists of two parts, a transmitter and a receiver, which are usually installed in pairs on both sides or on the top of the Automatic Gate. The transmitter emits multiple parallel and evenly spaced beams of light to form an invisible protective barrier; the receiver is responsible for receiving these beams and monitoring the integrity of the light in real time. When a person or object enters the detection area of ​​the safety light curtain, that is, blocks part or all of the light, the receiver will immediately send a signal to the control system to trigger the automatic door to stop or reverse movement, thereby avoiding the occurrence of pinching accidents.

Workflow of safety light curtain
The workflow of the safety light curtain is simple and efficient. When the Automatic Gate is in standby mode, the safety light curtain continuously emits and receives light to maintain real-time monitoring of the detection area. Once a pedestrian or object approaches the automatic door and is about to pass through, the sensor of the Automatic Gate (such as a microwave sensor or an infrared sensor) will detect this behavior and send a door opening signal to the control system. However, before the Automatic Gate starts to move, the safety light curtain will once again confirm whether there are people or objects in the detection area. If everything is normal, the Automatic Gate will open smoothly; if any obstruction appears within the detection range of the safety light curtain, the control system will immediately interrupt the door opening command and may trigger reverse movement or an emergency stop mechanism to ensure safety.

Advantages and features of safety light curtains

High sensitivity and fast response: The safety light curtain uses high-precision sensors and fast processing chips to detect obstructions and respond in a very short time, effectively avoiding the occurrence of pinching accidents.

Comprehensive protection and no-dead-angle monitoring: Through the layout of multiple parallel beams of light, the safety light curtain can achieve full coverage and no-dead-angle monitoring of the detection area, ensuring that obstructions at any position can be discovered in time.
Easy to install and maintain: Safety light curtains usually adopt modular design, which is easy and quick to install; at the same time, they are compact, durable and low in maintenance cost.
Strong adaptability: Safety light curtains can be customized according to the type and size of automatic doors to meet the specific needs of different places; at the same time, they also support a variety of signal interfaces and communication protocols, which is easy to integrate with various control systems.
The role of safety light curtains in the safety performance of Automatic Gate
As an important part of the Automatic Gate safety system, the role of safety light curtains is crucial. It can not only provide timely protection when people or objects approach the automatic door to prevent the occurrence of pinching accidents; it can also ensure the stability and reliability of the automatic door during operation through real-time monitoring and rapid response mechanisms. In addition, safety light curtains can also improve the intelligence level of automatic doors, enabling them to better adapt to complex and changing traffic environments, and provide users with a safer, more convenient and comfortable traffic experience.
