¿Cuánto sabe sobre las cortinas de luz para ascensores?
1. ¿Qué es la cortina de luz del ascensor?
El ascensor cortina de luzes un dispositivo de protección de seguridad de tipo ligero, adecuado para ascensores de pasajeros y montacargas para proteger la seguridad de los pasajeros. Los cables de señales especiales se componen de cuatro departamentos principales. Hay 32 (16) tubos de transmisión de infrarrojos en el transmisor. Bajo el control de ACM, the transmitting y receiving tubes are turned on in sequence, y the car door area is continuously scanned from top to bottom to form a dense infrared protection cortina de luz. When the beam of light is blocked, the control system immediately outputs the door opening signal, y the car door stops closing y opens in reverse. El ascensor door can be closed normally until the passenger or the obstacle leaves the warning area, so as to achieve the purpose of protecting the safety of the passengers.
2.The working principle of ascensor cortina de luz
un lado de la ascensor cortina de luz is installed with multiple infrared emitting tubes at equal intervals, y the other side has the same number y same arrangement of infrared receiving tubes. Each infrared emitting tube has a corresponding infrared receiving tube y is installed in the same straight line superior. When there is no obstacle between the infrared transmitting tube y the infrared receiving tube on the same line, the modulated signal (optical signal) sent by the infrared transmitting tube can reach the infrared receiving tube smoothly. After the infrared receiving tube receives the modulation signal, the corresponding internal circuit outputs a low level, y in the case of obstacles, the modulation signal (optical signal) sent by the infrared transmitting tube cannot reach the infrared receiving tube smoothly. At this time, the infrared receiving tube.The tube can not receive the modulation signal, y the corresponding internal circuit output is high level. When no object passes through the cortina de luz, the modulated signals (optical signals) sent by all infrared transmitting tubes can smoothly reach the corresponding infrared receiving tubes on the other side, so that all internal circuits output low level. In this way, information on the presence or absence of an object can be detected by analyzing the state of the internal circuit.
3. Cómo probar las cortinas de luz
① Check whether the ascensor safety cortina de luz is firmly fixed on the equipment to be equipped, whether the transmitter y receiver of the ascensor cortina de luz sensor are in the same plane, y the protection area bounded by the transmitter y the receiver should be in the plane a rectangle of
② Check whether the transmitter y receiver of the ascensor safety cortina de luz are accurately assembled with their respective cables, y whether the cable terminals are accurately y firmly connected to the power supply y control unit
③ Encienda el ascensor safety cortina de luz sensor. At this time, the cortina de luz sensor starts self-checking, synchronization y self-calibration. After about 1 second, the yellow indicator light of the transmitter is stable, y the indicator lights of the receiver are all off, indicating that the cortina de luz sensor is in normal operation. working status.
4. How to install cortina de luz
1.Tools y materials: hy drill, test pen multímetro, Phillips screwdriver, flat-blade screwdriver, cable ties, diagonal pliers, mobile power strip, new cortina de luz, etc.② Check whether the transmitter y receiver of the ascensor safety cortina de luz are accurately assembled with their respective cables, y whether the cable terminals are accurately y firmly connected to the power supply y control unit
③ Encienda el ascensor safety cortina de luz sensor. At this time, the cortina de luz sensor starts self-checking, synchronization y self-calibration. After about 1 second, the yellow indicator light of the transmitter is stable, y the indicator lights of the receiver are all off, indicating that the cortina de luz sensor is in normal operation. working status.
4. How to install cortina de luz
2.Simply check whether the original power box, signal cable, cortina de luz strip (transmitter-receiver) work normally by means of a multímetro, replacement method, etc., y replace the damaged parts.
3. The installation process of the new cortina de luz is as follows:
A. Cut off the ascensor power y remove the old cortina de luz or safety touch panel, power box y signal cable.
B. Install cortina de luz strip:
Rules: The distance between the two cortina de luz strips is not less than 6mm when the door is closed, y the distance between the lower part of the cortina de luz y the sill of the car door is 2~10mm, the height difference between the two cortina de luzs is not more than 1mm, y the verticality is not more than 2m.

Make sure that all parts are connected securely. Open y close the car door by hy several times to ensure that the cables are arranged in a reasonable direction. Confirm again that the power box y power supply meet the needs of the cortina de luz. Power on the ascensor in the maintenance state, y observe the power indicator light through the shielding method to see if it responds normally. Finally, confirm that the ascensor can reopen the door by blocking the cortina de luz when the ascensor está en el estado de funcionamiento automático.
5. How to judge the quality of the cortina de luz
① Clasificación IP (clasificación IP superior a 65)
② Fuerza antiinterferente
③ Intensidad anti-luz
