Enhanced Elevator Light Curtain Environmental Protection And Energy Saving Needs

Enhanced Elevator Light Curtain is a kind of light elevator door safety protection device, suitable for passenger ladder, cargo ladder, to protect the safety of passengers. By the installation of the elevator car door on both sides of the infrared transmitter and receiver, installed in the car top of the power box and dedicated flexible cable composed of four parts. There are 32 (16) infrared emission tubes in the transmitter. Under the control of the MCU, the transmitting and receiving tube is opened, and the car door area is continuously scanned from top to bottom to form a dense infrared protection light curtain. When any of the light is blocked, the control system immediately outputs the door opening signal, the car door stops and reverses the opening until the passenger or obstruction leaves the guard area and the elevator door can normally close to achieve the purpose of safety protection. Can avoid the accident occurred in the elevator folder.

Infrared light curtain transmitter in the program under the control of a launch tube by a single beam of infrared radiation, while the corresponding detection of a receiving tube received signal to form a detection circuit.

 If the beam infrared rays are blocked by the object, the corresponding receiving tube has no signal output, and if the beam is blocked by the object, the control system is judged as normal. If the beam is blocked by the object, the corresponding receiving tube has no signal output, Or if the output, but did not reach the desired strength, the control system to determine the abnormal situation, the control system will send a signal to the elevator door system, so that the elevator door is turned off in turn open.

The light curtain control system controls all the infrared emission tubes to emit the infrared light beam in sequence, and sequentially judges the output signal intensity of the corresponding infrared receiving tube in sequence, and performs cyclic scanning to form a stealth infrared protection light curtain. The emission of the infrared emission tube and the reception of the corresponding infrared reception tube are synchronized by the control program.

Enhanced Elevator Light Curtain is a kind of use of photoelectric induction principle made of elevator door safety protection device, applicable to all elevators, to protect the safety of passengers entering and leaving the elevator. Enhanced Elevator Light Curtain is installed by the elevator car door on both sides of the infrared transmitter and receiver and dedicated flexible cable composed of three parts. For environmental and energy needs, more and more elevators have saved the power box. Part of the brand's light curtain due to poor resistance to electromagnetic interference, but also had to use the power box. But with the popularity of green elevator concept, free power box light curtain is a trend. Because 220V to 24V in the process is bound to lose a lot of energy.

There are several infrared emission tubes in the light curtain. At the control of the MCU, the transmitting and receiving tube is opened in turn, and the light emitted by a transmitting head is received by multiple receiving heads to form a multi-scan. Through this top-down continuous scanning car door area, the formation of a dense infrared protection light curtain. When any of the light is blocked, since the photoelectric conversion can not be achieved, the light curtain judgment is blocked, thereby outputting an interrupt signal. The interrupt signal can be a switch signal, it can be high and low level signal. The control system receives the signal from the light curtain, immediately output the door open signal, the car door is closed and reversal open until the passengers or obstacles to leave the alert area after the elevator door can be closed normally, so as to achieve the purpose of security, To avoid the accident occurred in the elevator folder.
