The secret of the elevatorsafety guarantee of elevator light curtain

As an indispensable means of transportation in modern buildings, elevators have been closely related to people's daily lives. With the use of elevators, elevator safety accidents have attracted more and more public attention. Among them, accidents of people trapping or hitting cargo during the elevator closing process happen from time to time. Early elevator door safety protection devices generally used safety touch panel switches. This type of protection has low sensitivity and slow response. It needs to hit passengers during use to take effect, and it can't identify passengers' clothes, skirts, carrying pockets and other soft items. Nowadays, special elevator light curtains are more commonly used.

Recently, Autonics launched the 5-point cross-net elevator protection light curtain BWE series to expand its product portfolio to meet the strong elevator market demand.

The BWE series of all-round elevator light curtains are equipped with 17 or 32 pairs of optical axes and support up to 154 crossed beams to maximize passenger safety. Products equipped with 32 pairs of optical axes have dense beams and can detect obstacles of about 60 mm between any elevator doors. The products equipped with 17 pairs of optical axes are also suitable for some specific installation methods and have a better cost performance.

4/5 point light cross screen light curtain

Minimize detection blind spots

When the control system instructs a certain infrared emitting tube to transmit, in addition to receiving the signal of the receiving tube facing the emitting tube, it can also receive the signals of the adjacent receiving tubes one by one. Every time you receive a signal from a receiving tube, it is like observing the situation on that "line". Scan all these "observation lines" once to form a crossed beam. With crossed beams, fewer infrared emitting tubes and infrared receiving tubes can be used to form a denser infrared protective light curtain, with almost no "observation" blind spots

Action test (light emission stop) function and self-diagnosis function

Illuminator/receiver circuit diagnosis, direct light detection, over-current detection

The infrared light curtain elevator door protection system is composed of light emitters and light receivers, which are installed on both sides of the elevator car door. The infrared transmitter can emit infrared detection beams in turn, and the infrared receiver can detect these beams in turn, so as to form dozens to hundreds of infrared protective light curtains on the plane of the elevator car door. When passengers or objects enter and exit the plane of the elevator car door and block any beam in the infrared light curtain scanning process, the light curtain control system will detect it and output a signal to the elevator car door system to reverse the closing elevator door Open to protect passengers.

The BWE series detection device has excellent environmental stability, built-in power supply reverse connection protection, output short-circuit overcurrent protection, and self-diagnosis function. The company's specially developed cross-net technology optimizes the safety of the product and ensures that the cross beam can be maintained until the elevator door is closed. So as to provide the greatest safety guarantee for elevator passengers.
