The elevator light curtain is a door system safety protection device consisting of four parts: an infrared transmitter and receiver installed on both sides of the elevator car door, a power box installed on the top of the car, and a special flexible cable.
Product features:
High sensitivity: Using advanced infrared beaming technology, effectively preventing accidents caused by pinching.
Strong anti-interference ability: Using a unique anti-interference algorithm, it can effectively resist external interference such as sunlight and lights, ensuring stable and reliable operation.
Easy to install and maintain: Modular design, easy installation and maintenance, which can effectively reduce customer costs.
Product advantages:
Improve safety: High sensitivity and wide coverage effectively prevent pinching accidents and ensure passenger safety.
Enhance reliability: Strong anti-interference ability ensures stable operation of elevators in various environments.
Reduced operating costs: Easy to install and maintain, reducing customers’ later maintenance costs.
Enhance brand image: Using high-quality elevator light curtains, it highlights the brand’s emphasis on safety and enhances brand image.
Working principle:
There are several infrared transmitting tubes in the transmitting end of the light curtain. Under the control of the microcontroller unit, the transmitting and receiving tubes are turned on in sequence, and the light emitted by one transmitting head is received by multiple receiving heads in sequence, forming a multi-channel scan. By continuously scanning the car door area from top to bottom, a dense infrared protection light curtain is formed. When any beam of light is blocked, since the back-end circuit of the receiving head cannot realize photoelectric conversion, the light curtain determines that there is an obstruction, so it outputs an interrupt signal to the door machine. This interrupt signal can be a switch signal or a high or low level signal. After the elevator door machine receives the signal from the light curtain, it immediately outputs a door opening signal, and the car door stops closing and reverses to open until the passengers or obstacles leave the warning area. The elevator door can be closed normally, thereby achieving the purpose of safety protection and avoiding the occurrence of elevator pinching accidents.
Connection method:
- They are waterproof cable plugs, make sure they are connected firmly and properly.
- For standard central opening doors, the door detector set contains 2 pieces of 3.5m cables.
- For side opening doors, the door detector set contains 1 piece of 2.5m cable and 1 piece of 4.5m cable.
- For 4-panels-central-opening doors, the door detector set contains 2 pieces of 5m cables.
