Problems solved by technology

[0004] The biggest problem with ray tracing devices is that the light source causes the photoelectric sensor to saturate
When the light navigation electric door is very close to the light source and the photoelectric sensor device, the saturation phenomenon of the photoelectric sensor device will occur, which will lead to the failure of the light navigation principle
The common way to solve light saturation is to increase the electronic shutter or mechanical shutter, but it will lead to a significant increase in cost

Embodiment

[0045] refer to figure 1 , the method for preventing light saturation of a ray tracing trackless electric door in this embodiment is applied to a ray tracing trackless electric door. Induction device 50, electric door moving end 10 is connected to electric door fixed end 20 through telescopic middle net 30; The induction device 50 is respectively fixed on the top of the fixed end 20 of the electric door and the moving end 10 of the electric door. Further, the photoelectric induction device 50 and the light source 40 constitute an optical navigation system. The photoelectric induction device 50 receives the light emitted by the light source 40 to generate an induction electrical signal, and sends the induction electrical signal to the electric door mobile terminal 10. The signal navigates the electric door mobile terminal 10, and the specific principle of ray tracing navigation can refer to the prior art.

Abstract

The invention relates to a method of preventing light saturation of a light tracking trackless electric door and the trackless electric door. An electric door moving end in the trackless electric dooris connected with an electric door fixing end through a stretchable middle net, and a light source and a photoelectric induction device are fixed to the top end of the electric door moving end and the top end of the electric door fixing end respectively. The method comprises the steps that S11, the light source emits light, and the photoelectric induction device receives the light emitted by thelight source; and S12, the brightness of the light source is adjusted according to the intensity of the induction light received by the photoelectric induction device. According to the method, the light intensity of the light source is timely adjusted, and therefore the light saturation phenomenon of the photoelectric induction device can be effectively avoided, the photoelectric induction devicecan be located in an effective working light intensity range all the time, and the stable operation of the electric door is guaranteed.

Description

technical field [0001] The invention relates to the field of trackless electric doors, and more specifically relates to a light-tracing trackless electric door method for preventing light saturation and the trackless electric door. Background technique [0002] As a kind of access control device, trackless electric door (trackless telescopic door) can be installed at the entrances and exits of residential quarters, industrial parks, shopping malls, etc. And easy maintenance, widely used. [0003] For the ray tracing trackless electric door, the principle of the photoelectric induction device is to convert the intensity of light into the magnitude of voltage or current. The stronger the light, the greater the voltage or current. When the light intensity exceeds a certain threshold and the voltage and current cannot continue to increase , this phenomenon is photoelectric saturation. [0004] The biggest problem with ray tracing devices is that the light source saturates the ...
