In one embodiment of the present invention, the allowable maximum offset of the sensing device 20 in the vertical direction may be set to 0.1m, which is generally caused by road jolts, so that the light source 30 and the sensing device 20 are not at the same level, and it is understood that in other embodiments of the present invention, the allowable maximum offset may be 0.08m, 0.09m, 0.11m, 0.15m, 0.2m, etc., which is not limited in particular.

The electric signal obtained by such conversion is sent to the signal processing unit 23, and the offset direction of the electric gate 50 is obtained.

In an embodiment of the present invention, the optical signal emitting device 10 may employ an LED light source.
Referring also to fig. 3, the principle of detecting the offset direction and the offset distance of the sensing device 20 specifically is as follows:
First, light is emitted by the optical signal emitting device 10, and is irradiated onto a certain photoelectric converter of the photoelectric conversion device 22 through the transformation of the optical lens 21, it is understood that when the directions of the door heads 51 are different, the positions of the optical signal emitting device 10 irradiated onto the photoelectric conversion device 22 are also different;
next, the photoelectric conversion device 22 converts the optical signal received by the optical lens 21 into an electrical signal according to a preset ratio;
Then, the signal processing unit 23 detects the electric signal intensity of each photoelectric converter on the photoelectric conversion device 22 in real time, and the actual offset distance of the sensing device 20 can be calculated by the electric signal intensity and the minimum resolution distance of each photoelectric converter, and the calculation formula is as follows:
where xi is a voltage value of each photoelectric converter obtained by proportional conversion according to the optical signal intensity, n is the number of photoelectric converters, and p is the minimum resolution distance of the sensing device 20, that is, the actual offset distance corresponding to the width of each photoelectric converter;
finally, according to the calculated actual offset distance of the sensing device 20, the offset direction of the electric door 50 can be determined, and the signal processing unit 23 controls the electric door 50 to automatically correct the deviation.
As a practical application of the present invention, for example:
The distance between the door post 30 and the door post 40 is 10m, the focal length of the optical lens 21 is 10mm, the sensing accuracy of the sensing device 20 is 8mm, the maximum sensing offset distance of the sensing device 20 is 0.8m, and the allowable offset of the sensing device 20 in the vertical direction is 0.1m, then:
(1) The number of photoelectric converters and the height and width of the photoelectric converters are calculated as follows:
Firstly, according to the distance between the gate post 30 and the gate post 40 and the focal length of the optical lens 21, the maximum reduction multiple of the optical lens 21 is calculated to be 10m/10 mm=1000, and if the offset distance of the sensing device 20 relative to the preset moving direction is set to be d, the minimum distance between the image formed by the optical signal transmitting device 10 on the photoelectric conversion array and the center of the photoelectric conversion array is set to be d/1000;
next, the width of the individual photoelectric converter is calculated from the sensing accuracy and the maximum reduction factor of the optical lens 21: 8 mm/1000=8um;
then, the number of photoelectric converters can be calculated to be 0.8m/8 mm=1000 according to the sensing accuracy and the maximum offset distance of the sensing device 20;
next, from the width of the photoelectric converters and the number of the photoelectric converters, the width of the photoelectric conversion array can be calculated to be 8um×1000=8 mm;
Finally, according to the allowable deviation of the sensing device 20 in the vertical direction being 0.1m and the maximum reduction multiple of the optical lens 21, the height of the photoelectric conversion array is calculated as: 0.1 m/1000=100 um
In summary, the width of the photoelectric conversion array is 8mm, the height of the photoelectric conversion array is 0.1mm, the photoelectric conversion array comprises 1000 photoelectric converters, and each photoelectric converter has a width of 8um and a height of 0.1mm.
(2) The offset distance calculation method of the sensing device 20 is as follows:
firstly, inputting voltage values x1, x2, …, xn obtained by proportionally converting n photoelectric converters according to the intensity of an optical signal, and a minimum resolution distance p of the sensing device 20, namely, the actual offset distance corresponding to each photoelectric converter obtained by the calculation is 10mm;
Then, the offset distance y of the output sensing device 20:
Wherein p=10mm, xi is a voltage value corresponding to one tenth of the difference of the optical signal intensity, and n=1000;
In summary, the sensing device 20 can obtain the actual offset distance y of the electric door 50, further determine whether the movement direction of the electric door 50 is offset, and when the movement direction is offset, the signal processing unit 23 controls the electric door 50 to automatically correct the deviation.
According to the invention, the sensing device is used for detecting the relative directions of the optical signal transmitted by the optical signal transmitting device and the electric door, so that the offset direction of the electric door is obtained, the structure of the trackless electric door is simplified while the trackless electric door is ensured to be free from deflection, the use cost of the trackless electric door is reduced, and the service life of the trackless electric door is prolonged; in addition, the sensing device can stop closing the electric door when detecting that the obstacle passes when the electric door is closed, so as to prevent collision.
