Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control, and particularly relates to an automatic calibration system for an automatic test machine of an SFP optical module. Background Art

[0002] The SFP optical module is a hot-pluggable small package module with an SFP package, with a maximum rate of up to 10.3G and an LC interface. The SFP optical module is mainly composed of a laser. The SFP classification can be divided into rate classification, wavelength classification, and mode classification;

[0003] As a core component of optical communication, the testing process of the optical module is particularly important. The purpose of the test is to ensure that the performance indicators of the optical module meet the requirements, so as to meet the usage requirements of the device. The performance testing of the optical module mainly includes transmission distance testing, temperature performance testing, humidity performance testing, and reliability testing.

[0004] However, in the current automatic test machine for SFP optical modules, the modules are loaded in a cartridge, with 20 pieces loaded in each cartridge. They are transported to the test machine entrance by an upper board machine, and then the test machine detects the SFP optical modules. In this process, although the cartridge loading of the SFP optical modules can increase the number of detections per single time of the test machine, a certain amount of time is consumed during the loading process of the SFP optical modules, thus affecting the overall efficiency of the test machine for detecting the SFP optical modules. Summary of the Invention

[0005] Aiming at the above-mentioned disadvantages of the prior art, the present invention provides an automatic calibration system for an automatic test machine of an SFP optical module, which solves the technical problems put forward in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] An automatic calibration system for an automatic test machine of an SFP optical module, comprising:

[0008] A transmission module, which is used to receive an SFP optical module, transmit the SFP optical module to a testing machine, an acquisition module, which is used to acquire the image data of the SFP optical module received on the transmission module, a logic unit, which is used to set the operation stage of the acquisition module and the acquisition logic when acquiring the image data of the SFP optical module, a selection unit, which is used to receive the image data of the SFP optical module acquired in the acquisition module, select and store the image data of the SFP optical module, a parameter source module, which is used to upload the specification parameters of the SFP optical module, construct a 3D model of the SFP optical module based on the specification parameters of the SFP optical module and store it, an identification unit, which is used to obtain the image data of the SFP optical module stored in the selection unit, perform a similarity comparison between the obtained image data of the SFP optical module and each 3D model of the SFP optical module constructed in the parameter source module, and identify the 3D model of the SFP optical module with the highest similarity to the image data of the SFP optical module, a feedback unit, which is used to receive the 3D model of the SFP optical module identified by the identification unit and feedback the 3D model of the SFP optical module to the robotic arm module, a robotic arm module, which is used to grab the SFP optical module transmitted on the transmission module, adjust the placement state of the SFP optical module, and put it back again, a monitoring module, which is used to monitor the operation state of the testing machine, a jump module, which is used to receive the operation state of the testing machine monitored in the monitoring module, refresh the system jump based on the operation state of the testing machine, and jump to the transmission module to run again.

[0009] The transmission module is interconnected with the acquisition module through a local area network. The lower level of the acquisition module is electrically connected to the logic unit and the selection unit through a medium. The acquisition module is interconnected with the parameter source module through a local area network. The lower level of the parameter source module is electrically connected to the identification unit and the feedback unit through a medium. The identification unit is interconnected with the selection unit through a local area network. The parameter source module is interconnected with the robotic arm module, the monitoring module and the jump module through a local area network. The robotic arm module is interconnected with the feedback unit through a local area network.

[0010] Furthermore, the transmission module is integrated by several groups of conveyor belts. The several groups of conveyor belts are connected to each other to continuously transmit the finished SFP optical module for the testing machine to receive the SFP optical module. The transmission module runs to monitor the operation state of the system in real time. At the end of each system operation, it resets and runs to execute the operation of transmitting the next group of SFP optical modules for the testing machine to receive the SFP optical module.

[0011] Further, the SFP optical module image data acquisition logic set in the logic unit, that is, when the acquisition module runs to acquire the SFP optical module image data, the setting of the acquisition frequency. The selection unit is set with SFP optical module image data selection logic. The selection unit selects a set of SFP optical module image data from the received SFP optical module image data based on the selection logic, and stores the selected SFP optical module image data after the selection of the SFP optical module image data.

[0012] Further, the SFP optical module image data selection logic set in the selection unit is expressed as:

[0013] Logical Step1: Obtain the SFP optical module image data acquired by the acquisition module based on the acquisition logic, traverse all the SFP optical module image data, and perform color recognition on the SFP optical module image data;

[0014] Logical Step2: Based on the color recognition result of the SFP optical module image data, extract the contour image in the SFP optical module image data based on the color recognition result;

[0015] Logical Step3: Capture the largest set of contour images in the contour image of the SFP optical module image data, perform rectangular determination on the captured contour image, and perform boundary distance determination on other contours from the largest set of contour images;

[0016] Logical Step4: Select the largest set of contour images in the SFP optical module image data as a rectangle, and the set of SFP optical module image data with the closest boundary distance from other contour images to the largest set of contour images;

[0017] Among them, the SFP optical module image data contains a complete conveyor belt. The largest set of contour images in the SFP optical module image data corresponds to the conveyor belt. Other contour images are all contour images except the largest set of contour images in the SFP optical module image data. Other contour images correspond to the SFP optical module.

[0018] Further, when the parameter source module constructs the 3D model of the SFP optical module based on the specification parameters of the SFP optical module, the constructed 3D model of the SFP optical module is in the placed state in the 3D space where it is located, which is the placed state when the SFP optical module is received by the testing machine and performs the testing operation in the testing machine.

[0019] Further, the similarity between the SFP optical module image data and the 3D model of the SFP optical module in the recognition unit is obtained by the following formula:

[0020]

[0021] In the formula: sim(α, β) is the similarity between the SFP optical module image data α and the 3D model β of the SFP optical module; is the feature vector of the SFP optical module image data α; n0 is the total amount of perspective images applied on the 3D model β of the SFP optical module; n is the set of perspective images applied on the 3D model β of the SFP optical module; is the feature vector of the perspective image on the 3D model β of the i-th group of SFP optical modules; γ is a constant;

[0022] where 1 ≤ γ ≤ n0, and the value of γ follows The larger the value, the larger the value of γ; conversely, the smaller the value of γ.

[0023] The larger the value of sim(α, β), the higher the probability that the SFP optical module corresponding to the source SFP optical module of the SFP optical module image data is consistent with the source specification parameters of the 3D model of the SFP optical module; conversely, the lower the probability of consistency.

[0024] Furthermore, during the operation stage of the robotic arm module, it receives in real time the 3D model of the SFP optical module fed back by the feedback unit, and synchronously obtains the model image of any perspective on the 3D model of the SFP optical module. The robotic arm module is integrated by a pneumatic suction cup and a robotic arm. The pneumatic suction cup on the robotic arm module grabs the SFP optical module transmitted on the transmission module, and further applies the robotic arm to adjust the placement state of the grabbed SFP optical module based on the perspective of the model image source, so that the placement state of the SFP optical module transmitted on the transmission module after being adjusted by the robotic arm module is consistent with the placement state of the 3D model of the SFP optical module in its three-dimensional space.

[0025] Furthermore, after receiving the SFP optical module, the testing machine runs synchronously to test the SFP optical module, monitors the operating state of the testing machine monitored by the monitoring module, that is, the start and stop of the testing machine. When the jump module receives that the operating state of the testing machine is started, it refreshes the system jump and jumps to the collection transmission module to run again, and applies the transmission module to transmit the SFP optical module again.

[0026] Adopting the technical solution provided by the present invention, compared with the known public technology, it has the following beneficial effects:

[0027] The present invention provides an automatic calibration system for an SFP optical module automatic testing machine. During the operation of this system, the process of the SFP optical module being transmitted to the testing machine is set to be continuous, effectively improving the comprehensive efficiency of the testing machine for detecting the SFP optical module. Moreover, before the SFP optical module is transmitted to the testing machine, it can be automatically calibrated to ensure that all the SFP optical modules transmitted to the testing machine can complete the test with the same placement posture, making the test results of the testing machine for the SFP more accurate. And the configured model construction logic enables the testing machine to automatically identify and detect any model of SFP optical module, effectively reducing the manual debugging participation during the use of the testing machine, and making the detection process of the SFP optical module by the testing machine faster and more intelligent.

[0044] Among them, the image data acquisition logic of the SFP optical module set in the logic unit 21, that is, the setting of the acquisition frequency when the acquisition module 2 operates to acquire the image data of the SFP optical module. The selection unit 22 is set with the image data selection logic of the SFP optical module. The selection unit 22 selects a group of image data of the SFP optical module from the received image data of the SFP optical module based on the selection logic, and stores the selected image data of the SFP optical module after the selection of the image data of the SFP optical module;

[0045] The parameter source module 3 is provided with sub-modules at a lower level, including:

[0046] The recognition unit 31 is used to obtain the image data of the SFP optical module stored in the selection unit 22, apply the obtained image data of the SFP optical module to perform a similarity comparison with each 3D model of the SFP optical module constructed in the parameter source module 3, and recognize the 3D model of the SFP optical module with the highest similarity to the image data of the SFP optical module;

[0047] The feedback unit 32 is used to receive the 3D model of the SFP optical module recognized by the recognition unit 31 and feedback the 3D model of the SFP optical module to the robotic arm module 4;

[0048] Among them, when the parameter source module 3 constructs a three-dimensional model of the SFP optical module based on the specification parameters of the SFP optical module, the three-dimensional model of the SFP optical module built is in the shelving state in the three-dimensional space where it is located, which is the shelving state when the SFP optical module is received by the testing machine and performs a testing operation in the testing machine;

[0049] The similarity between the SFP optical module image data and the three-dimensional model of the SFP optical module in the recognition unit 31 is obtained through the following formula:

[0050]

[0051] In the formula: sim(α,β) is the similarity between the SFP optical module image data α and the three-dimensional model β of the SFP optical module; is the feature vector of the SFP optical module image data α; n0 is the total amount of application perspective images on the three-dimensional model β of the SFP optical module; n is the set of application perspective images on the three-dimensional model β of the SFP optical module; is the feature vector of the i-th group of perspective images on the three-dimensional model β of the SFP optical module; γ is a constant;

[0052] Among them, 1 ≤ γ ≤ n0, and the value of γ follows The larger, the larger the value of γ, and vice versa, the smaller the value of γ;

[0053] The transmission module 1 is interconnected through a local area network with the acquisition module 2. The lower level of the acquisition module 2 is through the medium electrical logic unit 21 and the selection unit 22. The acquisition module 2 is interconnected through a local area network with the parameter source module 3. The lower level of the parameter source module 3 is electrically connected through the medium to the recognition unit 31 and the feedback unit 32.

The parameter source module 3 is interconnected through a local area network with the robotic arm module 4, the monitoring module 5 and the jump module 6. The robotic arm module 4 is interconnected through a local area network with the feedback unit 32.

[0054] In this embodiment, the transmission module 1 operates to receive the SFP optical module, transmits the SFP optical module to the testing machine. The acquisition module 2 synchronously acquires the SFP optical module image data received on the transmission module 1. The parameter source module 3 operates later to upload the specification parameters of the SFP optical module, constructs a three-dimensional model of the SFP optical module based on the specification parameters of the SFP optical module and stores it. The robotic arm module 4 grabs the SFP optical module transmitted on the transmission module 1 in real time, adjusts the shelving state of the SFP optical module, and then puts it back. Then the monitoring module 5 operates to monitor the operating state of the testing machine. Finally, the jump module 6 receives the operating state of the testing machine monitored in the monitoring module 5, refreshes the system jump based on the operating state of the testing machine, and jumps to the transmission module 1 to operate again, so as to be configured in the testing machine to continuously detect the SFP optical module;

[0057] And the similarity calculation formula of the image data of the SFP optical module and the three-dimensional model of the SFP optical module described above provides necessary operation data support for the operation of the robotic arm module 4.

[0058] Embodiment 2

[0059] At the specific implementation level, on the basis of Embodiment 1, this embodiment further specifically describes an automatic calibration system of an SFP optical module automatic tester in Embodiment 1 with reference to Figure 1 as shown:

[0060] The transmission module 1 is integrated by several groups of conveyor belts. The several groups of conveyor belts are connected to each other to continuously transmit the finished SFP optical module for the tester to receive the SFP optical module. The transmission module 1 runs to monitor the running state of the system in real time. At the end of each system operation, it resets and runs to perform the operation of transmitting the next group of SFP optical modules to the tester and the tester receiving the SFP optical module.

[0061] After receiving the SFP optical module, the tester runs synchronously to test the SFP optical module. The monitoring module 5 monitors the running state of the tester, that is, the start and stop of the tester. When the jump module 6 receives that the running state of the tester is start, it refreshes the system jump and jumps to the transmission module 1 to run again, and applies the transmission module 1 to transmit the SFP optical module again.

[0062] Through the above settings, the running logic of the system when cooperating with the tester to detect the SFP optical module is further defined.

[0063] As Figure 1 shown, the image data selection logic of the SFP optical module set in the selection unit 22 is expressed as:

[0064] Logical Step1: Obtain the SFP optical module image data collected by the acquisition module 2 based on the acquisition logic, traverse all the SFP optical module image data, and perform color recognition on the SFP optical module image data;

[0065] Logical Step2: Based on the color recognition result of the SFP optical module image data, extract the contour image in the SFP optical module image data based on the color recognition result;

[0066] Logical Step3: Capture the largest set of contour images in the contour image of the SFP optical module image data, perform rectangular determination on the captured contour image, and perform boundary distance determination on other contours with respect to the largest set of contour images;

[0067] Logical Step4: Select the largest set of contour images in the SFP optical module image data as a rectangle, and select the set of SFP optical module image data in which the other contour images are closest to the boundary of the largest set of contour images;

[0068] Among them, the SFP optical module image data contains a complete conveyor belt. The largest set of contour images in the SFP optical module image data corresponds to the conveyor belt. Other contour images refer to all contour images except the largest set of contour images in the SFP optical module image data. Other contour images correspond to the SFP optical module.

[0069] Through the above settings, the selection logic of the SFP optical module image data set in the selection unit 22 is defined, enabling the selection unit 22 to select the SFP optical module image data according to the specified selection logic.

[0070] As Figure 1 shown, the larger the value of sim(α,β), the higher the probability that the SFP optical module from which the SFP optical module image data is sourced corresponds to the SFP optical module with the specification parameters from which the SFP optical module 3D model is sourced. Conversely, the probability is lower.

[0071] As Figure 1 shown, during the operation stage of the robotic arm module 4, it receives in real time the SFP optical module 3D model fed back by the feedback unit 32 and synchronously obtains the model images from any perspective on the SFP optical module 3D model. The robotic arm module 4 is integrated by a pneumatic suction cup and a robotic arm. The pneumatic suction cup on the robotic arm module 4 grabs the SFP optical module transported on the transport module 1. Further, the robotic arm adjusts the placement state of the grabbed SFP optical module based on the perspective from which the model image is sourced, so that the placement state of the SFP optical module transported on the transport module 1 after being adjusted by the robotic arm module 4 is consistent with the placement state of the SFP optical module 3D model in its three-dimensional space.

[0072] Through the above settings, the operation logic of the robotic arm module 4 is further defined, enabling the robotic arm module 4 to adjust the SFP optical module to a shelved state during operation, thereby providing a necessary prerequisite for the tester to receive and detect the SFP optical module.

[0073] In summary, during the operation of the system in the above embodiments, the process of transmitting the SFP optical module to the tester is set to be continuous, effectively improving the comprehensive efficiency of the tester in detecting the SFP optical module. Moreover, before the SFP optical module is transmitted to the tester, it can be automatically calibrated to ensure that all SFP optical modules transmitted to the tester can complete the test with the same placement posture, making the test results of the tester for the SFP more accurate. Additionally, the configured model construction logic enables the tester to automatically and intelligently detect any model of SFP optical module, effectively reducing the manual debugging participation during the use of the tester and making the detection process of the SFP optical module by the tester faster and more intelligent.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
