introduction

 

Elevator equipment is progressing and safety-sensitive devices have increased potential due to the increasing number of elevators, and various manufacturers are investing in the research and development of sensors, which makes the safety technology of elevators have great progress. Voko Co.WECO) the largest manufacturer of optical curtains With an annual production capacity of 1,000,000 sensors and supply products to the whole world. Voko products are sold in more than 40 countries and have official representatives in Canada, Spain, France, Germany, Turkey, etc. . . is Voko company is specialized in introducing elevator light curtain equipment using infrared scanning techniques. According to the height and distance covered by the cabin door, the infrared sensor can support up to 48 transmitters and receivers on both sides. Inside the microcontroller and microprocessor digital control program, the infrared transmitter device is scanning the covered area at a high speed. By creating an obstacle, the infrared light curtain is cut off and quickly stops the output signal level until people and objects leave the warning area of the curtains and the signal is connected automatically. Such advanced protection equipment is necessary to have a fast and safe mechanism, but it is important to educate and strengthen the awareness of passengers when using the elevator in case of sudden system operation calmly and Show full awareness and react to provide more security for themselves and others.

 

What is an elevator light curtain?

 

You have definitely noticed the sudden changes in the cabin door when using the elevator, which is unavoidable. For the safety of the passengers and to save on the repair costs of the cabin door, as well as to improve the service of the elevator, it is necessary to predict the obstacle from the light curtain and avoid collision with the passengers.

The light curtain includes a transmitter and a receiver. A set of parallel transmitters is formed which transmits infrared light from the transmitter to the receiver to be received so that when an obstacle prevents the light beam from being sent to the receiver, the relay output of the signal to the control panel is disconnected or connected, immediately. The mechanical equipment stops the door from working to effectively protect the safety of passengers. The transmitter and receiver are installed on both sides of the elevator door, and are connected to the power box on the roof of the car by an interface cable. It has 32 infrared emission controller diodes and they are responsible for transmitting and receiving light rays so that they continuously scan the cabin door from top to bottom.

Therefore, these sensors can prevent elevator accidents and service elevators faster.
