Detailed Description

The embodiment of the invention provides an elevator light curtain control method, an elevator light curtain control device and electronic equipment.

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides an elevator light curtain control method, where an execution main body of the method may be a controller, and the controller may be implemented based on a light curtain and a door inverter integrated device. The method may specifically comprise the steps of:

and step S110, acquiring the positions of the door plates and obtaining the intervals between the door plates for executing the door opening and closing instructions.

In the process of opening and closing the door by the door machine, the controller monitors the door plate of the elevator to acquire the position of the door plate in real time and obtain the interval between the door plates.

And S120, adjusting the light intensity of the light emitting diodes of the elevator light curtain according to the adjusting stage of the interval between the door panels.

The controller adjusts the light intensity of the light emitting diodes of the elevator light curtain in real time according to the interval between the door plates. When the door is opened, the controller drives the door to open the door, and simultaneously opens the electronic switch of the light curtain light-emitting diode, and the light intensity of the light-emitting diode is stronger and stronger in the door opening process; when the door machine is closed, the controller drives the door machine to close, in the door closing process, the light intensity of the light emitting diode is weaker and weaker, the preset time, for example 90s, passes until the door machine is closed in place, and if the door is not opened, the electronic switch of the light emitting diode is closed, so that the light emitting diode enters a sleep mode.

In the process of adjusting the light intensity of the light-emitting diode, the light intensity of the light-emitting diode can be adjusted in a plurality of adjusting stages according to the intervals between the door plates and according to different adjusting modes.

In an embodiment, the adjustment of the light intensity of the light emitting diode can be adjusted in various ways, and this embodiment of the application only gives an example, and the step S102 includes:

step S121, obtaining output voltage of the light emitting diode according to the adjusting stage of the interval between the door plates;

and S122, adjusting the pulse width modulation duty ratio according to the output voltage of the light-emitting diode so as to adjust the light intensity of the light-emitting diode.

A change in the Pulse Width Modulation (PMW) duty cycle will result in a corresponding change in the output voltage of the light emitting diode. The output voltage is increased, and the light intensity of the light-emitting diode is enhanced; the output voltage is reduced and the light intensity of the light emitting diode is weakened.

When the controller obtains the output voltage of the light emitting diode according to the interval between the door plates, the controller can adjust the effective voltage of the light emitting diode to obtain the output voltage by adjusting the PMW duty ratio, and further achieve the purpose of adjusting the light intensity of the light emitting diode. In the door opening process, the controller synchronously increases the PMW duty ratio along with the gradual increase of the intervals between the door plates, so that the effective voltage of the light emitting diode is gradually increased, and the light intensity is stronger and stronger; in the process of closing the door, the controller reduces the PMW duty ratio synchronously along with the gradual reduction of the interval between the door plates, so that the effective voltage of the light-emitting diode is gradually reduced, the light intensity is weaker and weaker, and the light-emitting diode enters a sleep mode until the door machine is closed.

It should be understood that the adjustment range of the output voltage of the light emitting diode can be set according to actual requirements, for example, 0 to 3.3V, and for simplicity, 0 to 3.3V can be exemplified in the following embodiments.

According to the technical scheme provided by the embodiment of the invention, the embodiment of the invention obtains the positions of the door panels and the intervals between the door panels; and adjusting the light intensity of the light emitting diodes of the elevator light curtain according to the adjusting stage of the intervals between the door panels, wherein the smaller the interval between the door panels is, the weaker the light intensity of the corresponding light emitting diodes is. By the embodiment of the invention, the purposes of reducing power consumption and prolonging the service life of the light curtain are realized under the condition of not influencing the working efficiency.

Based on the above embodiment, further, as shown in fig. 3, the step S121 includes:

and S1211, when the spacing distance between the door plates is smaller than or equal to a preset threshold value, obtaining the output voltage of the light emitting diode according to a first formula.

According to the preset threshold value, the output voltage of the light emitting diode is divided into two stages. The first stage is executed when the spacing distance between the door panels is smaller than or equal to a threshold value, and the second stage is executed when the spacing distance between the door panels is larger than the threshold value.

The threshold value may be set according to actual needs, for example, the maximum distance between the door panels is 4000mm, that is, the distance between the door panels may be in the range of 0 to 4000mm, and the threshold value may be 1500 mm. For the sake of simplicity, this is exemplified in the following examples.

Further, the first formula is as follows:

y²＝ax

y is the output voltage of the light emitting diode, x is the interval between the door panels, and a is a preset coefficient.

And step S1212, when the interval distance between the door panels is larger than the width threshold value, obtaining the output voltage of the light emitting diode according to a second formula.

Further, the second formula is:

y＝b1+b2(x-m)/(M-m)

y is the output voltage of the light emitting diode, x is the interval between the door panels, b1 and b2 are a first voltage value and a second voltage value, b1+ b2 is equal to the maximum output voltage of the light emitting diode, M is the maximum door operator width, and M is a preset threshold value.

It should be understood that the coefficients and values in the first and second equations may be set according to actual requirements, and are exemplified by a being 0.0015, b1 being 1.5V, b2 being 1.8V, M being 4000mm, and M being 1500mm, that is, the range of possible values of the gantry crane interval is 0 to 4000 mm. Under the condition that the interval OP between the door plates obtained by the controller is less than or equal to 1500, according to a first formula y²Calculating to obtain the output voltage y of the light emitting diode as 0.0015; the spacing OP between the door panels>1500, the output voltage y of the led is calculated according to the second formula, i.e., 1.5+1.8 (x-1500)/2500. It can be known that the output voltage y of the light emitting diode ranges from 0V to 3.3V. For example, when x ═ xAt 1000mm, y is 1.225V according to the first formula; when x is 1600, y is 1.572V according to the second formula; when x is 2000mm, y is 1.86V according to the second formula.

According to the technical scheme provided by the embodiment of the invention, the light intensity of the light-emitting diode is adjusted into two stages through the threshold, the corresponding stage is determined according to the comparison between the interval between the door plates and the threshold, and the input voltage of the light-emitting diode is calculated by adopting the corresponding formula, so that the light intensity of the light-emitting diode is adjusted. By the embodiment of the invention, the purposes of reducing power consumption and prolonging the service life of the light curtain are realized under the condition of not influencing the working efficiency.

Based on the above embodiment, further, the step S121 further includes:

and obtaining the width of the actual gantry crane through self-learning, and obtaining the output voltage of the light emitting diode according to the ratio of the interval between the door plates to the width of the actual gantry crane. The actual door machine width is the maximum value that can be practically achieved for the spacing between the door panels.

The controller can obtain the actual width of the portal crane through self-learning, specifically, the controller obtains the width of the self-learning portal crane through self-learning, and then the actual width of the portal crane is obtained through calculation according to a corresponding formula, for example, the width of the self-learning portal crane is equal to the actual width of the portal crane/2 + 50. If the width of the self-detection door machine is 550mm, the width of the actual door machine is 1000 mm.

Then, the output voltage of the light emitting diode is obtained according to the ratio of the width of the actual door machine to the interval between the door plates, and the specific calculation formula can be expressed as follows:

y＝Bx/M′

b is the maximum output voltage of the led, e.g. 3.3V, and M' is the actual gate width.

If the actual width of the gantry crane is 2000mm, the calculation formula is that y is 3.3 x/2000.

Further, the actual door machine width obtained by the controller through self-learning is applied to the control method divided into a plurality of stages, and under the condition that the actual door machine width is less than or equal to the threshold value, the output voltage of the light emitting diode is obtained by directly adopting a first formula; under the condition that the width distance of the actual door machine is larger than the threshold value, a corresponding adjusting stage needs to be determined according to the interval between the door plates, and the output voltage of the light emitting diode is obtained according to a first formula or a second formula respectively.

According to the technical scheme provided by the embodiment of the invention, the actual width of the door machine is deduced through self-learning, so that the output voltage of the light emitting diode is obtained according to the ratio of the interval between the door plates to the actual width of the door machine, and the light intensity of the light emitting diode is further adjusted. By the embodiment of the invention, the purposes of reducing power consumption and prolonging the service life of the light curtain are realized under the condition of not influencing the working efficiency.
