Background
At present, a Micro-Electro-Mechanical System (MEMS) optical switch occupies a higher and higher market for the whole optical switch due to its low insertion loss, polarization insensitivity, and low power consumption. Mature MEMS optical switches are known as 1x2,1x4, 1x8, 1x 16. In recent years, MEMS optical switches are developed towards more channels, and the market demand for 1x32,1x48, 1x64 and 1x128 optical switches is increasing.
The MEMS optical switch is internally provided with a chip, and the rotating position of the chip is adjusted by changing the voltage of the chip. Each output port of the MEMS optical switch has an optimal set of chip control data, i.e., channel calibration. When the channel calibration value is changed, the optical output port of the MEMS optical switch can be changed. With the increase of the number of channels of the optical switch, the switching between the channels may have optical signal flash in a non-specified channel; the occurrence of such optical signals may cause the system to generate erroneous judgment.
The channel switching of the MEMS optical switch is usually directly switched from the coordinate origin of the chip to each channel calibration point, and manually checks the calibration data of all channels of all the optical switches, analyzes the calibration data, and selects out and discards the channels which may have optical signal flash. Therefore, more channels can be judged and abandoned, and the number of channels of the optical switch is wasted; secondly, because of manual selection, the working efficiency is low and the quality may be unstable.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for switching channels of an optical switch according to a first embodiment of the present invention. The method for switching the optical switch channel provided by the invention comprises the following steps:
s101: the method comprises the steps of obtaining a to-be-divided area including at least one to-be-divided channel calibration point, and carrying out quadrant division operation on the to-be-divided area, wherein the quadrant division operation divides the to-be-divided area into four quadrants.
In a specific implementation scenario, at least one pending channel calibration point is obtained. The coordinates of each channel to be calibrated point correspond to one optical switch channel, at least one optical switch channel is selected from the optical fiber array based on a preset selection standard, the x-axis driving voltage and the y-axis driving voltage corresponding to each selected optical switch channel are obtained, and the x-axis driving voltage and the y-axis driving voltage corresponding to each optical switch channel are used as the coordinates of the corresponding channel to be calibrated point.
In the implementation scene, the region to be divided comprises all the undetermined channel scaling points, and in other implementation scenes, the region to be divided comprises part of the undetermined channel scaling points. And performing quadrant division operation on the area to be divided, wherein the quadrant division operation divides the area to be divided into four quadrants. Referring to fig. 2, fig. 2 is a schematic view of a scene of an embodiment of an area to be divided into four quadrants according to the present invention.
S102: and acquiring a coordinate mean value of at least one to-be-determined channel calibration point included in each quadrant, taking the coordinate mean value as a current quadrant transit point of the corresponding quadrant, and acquiring a quadrant origin of quadrant division operation as a current quadrant center point.
In a specific implementation scenario, when performing the quadrant division operation, a quadrant origin (0,0) of the quadrant division operation is used as a current quadrant center point, and in other implementation scenarios, any point in the region to be divided may also be selected as the current quadrant center point, for example, (3, 5).
And acquiring the coordinate mean value of at least one to-be-determined channel calibration point included in each quadrant, and taking the coordinate mean value as the current quadrant transit point of the corresponding quadrant. For example, quadrant a includes four undetermined channel calibration points a (xa, ya), b (xb, yb), c (xc, yc), and d (xd, yd), and then coordinate mean (x, y), where x is (xa + xb + xc + xd)/4, and y is (ya + yb + yc + yd)/4. And taking the point corresponding to the coordinate mean value (x, y) as the current quadrant center point of the quadrant A. And acquiring the current quadrant transit point of each of the four divided quadrants according to the method.
In other implementation scenarios, if there may be a case where a calibration point of a to-be-determined channel is not included in a certain quadrant, the transit point in the current quadrant of the certain quadrant is not calculated.
S103: and screening at least one to-be-determined channel calibration point in each quadrant according to the current quadrant transit point and the current quadrant central point to obtain at least one qualified channel calibration point.
In a specific implementation scenario, at least one to-be-determined channel scaling point in each quadrant is screened according to a current quadrant transit point and a current quadrant central point, and at least one qualified channel scaling point meeting preset requirements in each quadrant is selected. Specifically, for each quadrant of the four quadrants acquired in step S101, a position distance from each undetermined channel calibration point in the current quadrant to a transit point in the current quadrant is calculated, if the position distance is smaller than a preset distance threshold, the undetermined channel calibration point corresponding to the position distance is determined to be an unqualified channel calibration point, the unqualified channel calibration point is eliminated, and if the position distance is greater than or equal to the preset distance threshold, the undetermined channel calibration point corresponding to the position distance is determined to be a qualified channel calibration point, and the qualified channel calibration point is retained, so that at least one qualified channel calibration point meeting the preset requirement in the current quadrant is screened out. The smaller the preset distance threshold is, the more calibration points of the undetermined channel which is possibly eliminated are, the more corresponding optical channels are eliminated, and the lower the probability of the optical signal flash is. The preset distance value can change along with the change of the density of the optical switch channels and the size of the distance between the light-emitting end faces of the optical channel optical fibers. In one implementation scenario, the optical switch is a 1 × 24 switch, the fiber core spacing of the end face of the channel fiber is about 65 μm, and the predetermined distance threshold may be 5V.
In other implementation scenarios, for each of the four quadrants acquired in step S101, the opening angle from the center point of the current quadrant to each to-be-determined channel calibration point in the current quadrant is calculated, with the center point of the current quadrant as an origin, the positive direction of the X axis as an initial position, and the counterclockwise direction as a rotation direction. Specifically, the slope of a connecting line from a calibration point of a channel to be calibrated to the central point of the current quadrant can be calculated, and the opening angle corresponding to the calibration point of the channel to be calibrated is calculated according to the atan function. And sequencing the field angles corresponding to each to-be-determined channel calibration point in the current quadrant according to the angle size to obtain a field angle sequence. The order may be from small to large or from large to small, and is not limited herein. And calculating the opening angle difference of every two adjacent opening angles in the opening angle sequence. When the opening angle difference is greater than or equal to a preset opening angle threshold (for example, 8 degrees), two undetermined channel calibration points corresponding to the opening angle difference are qualified channel calibration points and are reserved, when the opening angle difference is smaller than the preset opening angle threshold, the position distance from the two undetermined channel calibration points corresponding to the opening angle difference to a turning point in the current quadrant corresponding to the opening angle difference is calculated, one of the two undetermined channel calibration points corresponding to a longer position distance is reserved as a qualified channel calibration point, and the other corresponding to a shorter position distance is deleted as an unqualified channel calibration point. And screening out at least one qualified channel scaling point which meets the preset requirement in the current quadrant.
In other implementation scenarios, at least one to-be-determined channel calibration point in each quadrant may be screened in other calculation manners according to the current quadrant transit point and the current quadrant center point. For example, the distance between any two undetermined channel calibration points in the current quadrant is calculated, if the distance is smaller than a preset threshold value, the undetermined channel calibration point closer to the current quadrant transit point of the current quadrant is used as an unqualified channel calibration point, the unqualified channel calibration point is deleted, the undetermined channel calibration point farther from the current quadrant transit point of the current quadrant is used as a qualified channel calibration point, and the qualified channel calibration point is reserved, so that at least one qualified channel calibration point meeting the preset requirement in the current quadrant is screened out.
In other implementation scenarios, the coordinate density of at least one undetermined channel calibration point in the current quadrant may also be calculated, and if the coordinate density is smaller than a preset density threshold, all the undetermined channel calibration points in the current quadrant are taken as qualified channel calibration points.
S104: and acquiring an initial scaling point and a target scaling point in at least one qualified channel scaling point, and planning a switching path according to the initial scaling point and the target scaling point.
In a specific implementation scenario, an initial scaling point and a target scaling point are obtained from all the qualified channel scaling points, and the initial scaling point and the target scaling point may be set according to actual use requirements of a user, and a switching path is planned according to the initial scaling point and the target scaling point. Since the initial calibration point and the target calibration point are selected from the at least one qualified channel calibration point, a phenomenon of flashing of the optical signal does not occur.
In other implementation scenarios, in order to further improve the use quality of the optical switch, the position coordinate of the central point of the current quadrant may be appropriately shifted as needed, for example, adjusted from (0,0) to (3V,5V), and the specific value may be optimally adjusted according to the actual situation, with the goal of adjusting the com end so that there is no return light when the chip rotates back to the central point.
Referring to fig. 2, in the implementation scenario shown in fig. 2, a black solid circle Z0 is a current quadrant center point, black solid circles Z1-Z4 are current quadrant transit points of each quadrant, grid squares X1-X5 are unqualified channel index points eliminated when a distance from the current quadrant transit point of the quadrant where the grid square lattice X1-X5 is located is less than a preset distance threshold, and hollow circles P1-P10 are qualified channel index points. Wherein, the opening angle difference between the X1 opening angle and the P4 opening angle is smaller than the preset threshold, and the X1 is closer to the Z2, and thus is defined as a culling point.
When a switching path is planned according to the initial calibration point and the target calibration point, the switching path is planned by combining the position relationship of the initial calibration point and the target calibration point. When the initial calibration point and the target calibration point are in the same quadrant, acquiring a final quadrant transit point of the quadrant in which the initial calibration point and the target calibration point are positioned; the switching path is from the initial calibration point to the final quadrant transit point, and then from the final quadrant transit point to the target calibration point. For example, in fig. 2, the initial calibration point is P1, the target calibration point is P4, and the initial calibration point and the target calibration point are located in the same quadrant, then the current quadrant transit point Z2 of the quadrant where the initial calibration point and the target calibration point are located is taken as the final quadrant transit point, the switching path is from the initial calibration point P1 to the final quadrant transit point Z2, and then from the final quadrant transit point Z2 to the target calibration point P4.
When the initial calibration point and the target calibration point are in different quadrants, taking an initial quadrant transit point of the quadrant where the initial calibration point is located and a target quadrant transit point of the quadrant where the target calibration point is located; the switching path is from the initial calibration point to the initial quadrant transit point, then from the initial quadrant transit point to the current quadrant central point, then from the current quadrant central point to the target quadrant transit point, and then from the target quadrant transit point to the target calibration point. For example, in fig. 2, if the initial calibration point is P4 and the target calibration point is P9, and the two calibration points are located in different quadrants, the current quadrant transit point Z2 of the quadrant where the initial calibration point P4 is located is taken as the initial quadrant transit point, and the current quadrant transit point Z1 of the quadrant where the target calibration point P9 is located is taken as the target quadrant transit point. The switching path is from the initial calibration point P1 to the initial quadrant transit point Z2, from the initial quadrant transit point Z2 to the current quadrant center point Z0, from the current quadrant center point Z0 to the target quadrant transit point Z1, and from the target quadrant transit point Z1 to the target calibration point P9.
It can be known from the above description that, in this embodiment, an area to be divided, which includes at least one undetermined channel calibration point, is divided into four quadrants, a current quadrant transit point of each quadrant is acquired, a quadrant origin of quadrant division operation is acquired as a current quadrant center point, at least one undetermined channel calibration point in each quadrant is screened according to the current quadrant transit point and the current quadrant center point, at least one qualified channel calibration point is acquired, an initial calibration point and a target calibration point in the at least one qualified channel calibration point are acquired, a switching path is planned according to the initial calibration point and the target calibration point, the problem of optical signal flash of a non-designated channel is avoided, the production efficiency of an optical switch product is effectively improved, and the use quality of the optical switch product is improved.
Referring to fig. 3, fig. 3 is a schematic view of a scene of an embodiment of an area to be divided into sixteen quadrants according to the present invention. As shown in fig. 3, when the density of the channels is high, that is, the density of at least one to-be-determined channel calibration point is high, a quadrant division operation may be performed for each of the 4 quadrants shown in fig. 2. In the implementation scenario, quadrant division operation is performed on each of the 4 parent quadrant areas obtained by the last quadrant division operation, and in other implementation scenarios, quadrant division operation may be performed on any one or several of the 4 parent quadrant areas obtained by the last quadrant division operation. For example, the density degree of at least one to-be-determined channel calibration point in each parent quadrant region can be acquired, and quadrant division operation is performed only on parent quadrant regions with the density degree larger than a preset degree threshold.
In the implementation scenario shown in fig. 3, a black solid circle Z0 is a parent quadrant central point corresponding to the last quadrant division operation, black solid circles Z1-Z4 are parent quadrant transit points of each parent quadrant region, a squared frame in a field shape is an rejected unqualified channel index point, and an empty circle is a qualified channel index point. In the implementation scenario, after each quadrant segmentation operation is completed, a current quadrant transit point and a current quadrant central point corresponding to the quadrant segmentation are obtained, and at least one to-be-determined channel calibration point in each quadrant is screened according to the current quadrant transit point and the current quadrant central point. For example, in FIG. 3, at least one of the points to be calibrated for a channel is screened according to Z0 and Z1-Z4. And secondarily screening at least one to-be-determined channel calibration point after screening according to Z1-Z4, Z11-Z14, Z21-Z24, Z31-Z34 and Z41-Z44.
In the implementation scenario shown in fig. 3, it is determined whether the initial calibration point and the target calibration point are in the same parent quadrant region, and if so, the scenario is similar to the scenario in fig. 2 when the initial calibration point and the target calibration point are not in the same quadrant. For example, the initial calibration point is P2 and the target calibration point is P1. The initial calibration point is P2, the target calibration point is P1, the initial calibration point and the target calibration point are located in the same parent quadrant region (second quadrant), the current quadrant transit point Z21 of the quadrant where the initial calibration point P2 is located is obtained as an initial quadrant transit point, and the current quadrant transit point Z22 of the quadrant where the target calibration point P1 is located is obtained as a target quadrant transit point. The switching path is from an initial calibration point P2 to an initial quadrant transit point Z21, then from the initial quadrant transit point Z21 to a current quadrant center point Z2, then from the current quadrant center point Z2 to a target quadrant transit point Z22, and then from a target quadrant transit point Z22 to a target calibration point P1.
When the initial calibration point and the target calibration point are not in the same parent quadrant area, acquiring a parent quadrant central point corresponding to the last quadrant division operation, and acquiring an initial quadrant transit point of a quadrant where the initial calibration point is located and a target quadrant transit point of a quadrant where the target calibration point is located; the switching path is from the initial calibration point to the initial quadrant transit point, then from the initial quadrant transit point to the current quadrant central point, then from the current quadrant central point to the parent quadrant central point, then from the parent quadrant central point to the target quadrant transit point, and then from the target quadrant transit point to the target calibration point. For example, in the scenario shown in FIG. 3, the initial calibration point is P2 and the target calibration point is P3. The initial calibration point is P2 and the target calibration point is P3 located in different parent quadrant regions. And acquiring a parent quadrant central point Z0 corresponding to the last quadrant division operation, acquiring a current quadrant transit point Z21 of the quadrant where the initial calibration point P2 is located as an initial quadrant transit point, and acquiring a current quadrant transit point Z11 of the quadrant where the target calibration point P3 is located as a target quadrant transit point. Acquiring an initial quadrant central point Z2 corresponding to the initial quadrant transit point Z21, and acquiring a target quadrant central point Z1 corresponding to the target quadrant transit point Z11;
the switching path is from an initial calibration point P2 to an initial quadrant transit point Z21, from the initial quadrant transit point Z21 to an initial quadrant center point Z2, from the initial quadrant center point Z2 to a parent quadrant center point Z0, from the parent quadrant center point Z0 to a target quadrant center point Z1, from the target quadrant center point Z1 to a target quadrant transit point Z11, and from the target quadrant transit point Z11 to a target calibration point P3.
According to the description, in the embodiment, when the channel density is high, at least one of the 4 parent quadrant regions acquired by the last quadrant division operation is subjected to quadrant division operation, more undetermined channel calibration points can be effectively eliminated, the problem of optical signal flash of a non-designated channel is effectively solved, the production efficiency of an optical switch product is effectively improved, and the use quality of the optical switch product is improved.
