Description

Technical Field

[0001] The present invention relates to the field of displacement / position sensor assembly, and in particular to an intelligent pairing system and method based on the combination of software and hardware. Background Art

[0002] Displacement / position sensor is a sensor widely used in industry, automobile, aerospace and other fields to measure the angle / position changes of objects. With the rapid development of informatization and digitalization of industrial assembly production lines, data is automatically collected. Using data analysis and intelligent algorithms, the assembly process can be made more intelligent and efficient.

[0003] The applicant has discovered through research that during the manual assembly of the displacement / position sensor, the operator relies entirely on human experience to pair the stator winding and the rotor, and repeatedly debugs to achieve the optimal pairing effect. The data after matching cannot be digitally saved. After the winding is solidified offline, it is separated from the rotor. In the subsequent assembly process, the matched rotor cannot be found quickly, resulting in the assembly process being characterized by low efficiency, low accuracy, and unreliable reliability. Summary of the invention

[0004] In view of this, the present invention provides an intelligent pairing system and method based on the combination of software and hardware, which realizes a fast and accurate pairing process through the combination of software and hardware.

[0008] During the identification and measurement process, the laser diameter measuring device measures the rotor size; the server collects the measurement results of the rotor size and processes the data, stores the processed results in the database table, determines the corresponding gear position of the rotor on the rotor grading tray, and pushes the rotor to be stored in the storage position of the corresponding gear position;

The rotor to be paired is the rotor stored in the rotor classification tray; the sensor test system performs performance tests on the rotor to be paired and the winding to be paired, and returns the performance test results to the server. The server determines whether the rotor to be paired and the winding to be paired match based on the built-in intelligent pairing algorithm and the performance test results. If so, the storage position of the rotor in the intelligent pairing tray is automatically pushed. If not, the rotor position information of a suitable gear is pushed according to the algorithm until the pairing is successful. Among them, the rotor in the middle gear is selected as the rotor to be paired during the initial pairing.

[0010] Furthermore, the rotor-grading tray is divided into several gear areas according to the rotor size range, and the layout of each gear on the tray is designed according to the actual product size distribution;

[0011] A plurality of storage holes are arranged on the intelligent rotor, and position sensors are installed in the storage holes, and the storage holes are used to store the paired rotors; the position sensors are used to detect the rotor placement and removal process, and send the position sensor signal to the host computer; the host computer receives the tray signal and uploads the information to the server.

[0016] Furthermore, a unique identification is engraved on the storage hole of the smart rotor pairing tray, and a reminder light is provided;

[0017] The indicator light is used to control the indicator light at the storage position of the intelligent rotor pairing tray after the rotor is automatically pushed to the storage position of the intelligent rotor pairing tray. The server sends a lighting control instruction to the host computer of the intelligent rotor pairing tray. The lighting control instruction is used to control the lighting of the indicator light at the storage position.

[0018] In a second aspect, a smart pairing method based on the combination of software and hardware is provided, applying any one of the systems described in the first aspect, including:

[0019] The intelligent pairing software is deployed on the server side and interacts with the laser diameter gauge host computer through the standard HTTP protocol. It receives and processes the measurement results of the laser diameter gauge, eliminates abnormal measurement values, and takes the average value of normal data as the final measurement result. The software stores the number of rotors in each gear to realize intelligent push of subsequent processes.

[0020] The server pushes a simulation model that is consistent with the rotor-graded tray based on the size test results, and highlights the rotor gear position results, prompting the operator to put the rotor into the corresponding position on the tray;

[0021] The server communicates with the OCR visual recognition device through the standard HTTP interface protocol, receives the unique codes of the windings and rotors recognized by the OCR device, including the OCR number, the type of measured product, and the unique codes of the windings and rotors; calls the HTML of the OCR visual recognition device software, and embeds the OCR real-time display result interface in the pairing software interface, providing operators with a friendly and unified operation interface.

[0022] Furthermore, the method further comprises:

[0023] The server communicates with the sensor test system through the standard HTTP interface protocol and sends the unique code to the sensor test system;

[0025] The server determines whether the output voltage value at each angle is within the preset range, and determines whether the winding matches the rotor. If so, the simulation model consistent with the rotor matching tray is pushed on the interface, and the unique storage position of the rotor is highlighted, prompting the operator to put the rotor into the corresponding position in the tray; the server receives the placement and retrieval signal of the intelligent matching tray position sensor to verify whether the rotor is placed in the correct position;

[0026] If there is no match, the output voltage values ​​that are not within the preset range of the corresponding angle will be weighted and calculated to push a new rotor size information. The interface highlights the gear information of the new rotor. The operator takes a rotor in the gear and re-performs the pairing test until the match is successful. The number of rotors on the rotor tray at this gear is reduced by 1.

[0027] Furthermore, the method further comprises:

[0028] Establish a 3D model that matches the rotor grading tray and the rotor matching tray, and the position relationship between the model and the real object corresponds one to one;

[0029] Perform matching calculations, call up the corresponding model based on the calculation results, and dynamically highlight the location information on the model;

[0030] When the measured rotor size exceeds the gear range, a dialog box pops up to prompt, and you can choose to replace the test rotor or perform manual processing according to the prompt;

[0031] Each time the winding and the rotor are successfully matched, the number of rotors on the corresponding gear of the rotor-grading tray is reduced by 1. When the number of rotors on the gear is insufficient, the software interface prompts to replace the tray.

[0032] Furthermore, the winding and rotor air gap matching algorithm is guided by the idea of ​​measuring the voltage value at each rotation angle when the winding and the rotor are clamped together, and calculating whether the winding and rotor air gap size is within the winding and rotor matching standard range according to the voltage at each angle. If so, the winding and the rotor are successfully matched. If not, the measured value and the preset value are calculated to obtain a rotor size value that can meet the winding air gap size.

The intelligent pairing process is realized by combining software and hardware.

[0045] The server end is respectively connected to the upper computers of the laser diameter measuring device, the rotor grading tray, the intelligent rotor matching tray, the sensor testing system and the OCR visual recognition device;

[0046] The laser diameter measuring device measures the rotor size; the server collects the measurement results of the rotor size and processes the data, stores the processed results in the database table, determines the corresponding gear position of the rotor on the rotor grading tray, and pushes the rotor to be stored in the storage position of the corresponding gear position;

[0047] The OCR visual recognition device identifies the codes of the rotor to be paired and the winding to be paired. The rotor to be paired is the rotor stored in the rotor classification tray; the sensor test system performs performance tests on the rotor to be paired and the winding to be paired, and returns the performance test results to the server. The server determines whether the rotor to be paired and the winding to be paired match based on the built-in intelligent pairing algorithm and the performance test results. If so, the server automatically pushes the storage position of the rotor in the intelligent pairing tray. If not, the rotor position information of a suitable gear is pushed according to the algorithm until the pairing is successful. Among them, the rotor in the middle gear is selected as the rotor to be paired during the initial pairing.

[0048] Step 101: The intelligent pairing software is deployed on the server side, interacts with the laser diameter gauge host computer through the standard HTTP protocol, receives and processes the measurement results of the laser diameter gauge, eliminates abnormal measurement values, and takes the average value of normal data as the final measurement result. The software stores the number of rotors on each gear to realize intelligent push of subsequent processes;

[0049] Step 102: The intelligent pairing software pushes a simulation model consistent with the rotor-grading tray on the interface according to the size test result, and highlights the gear position result, prompting the operator to put the rotor into the corresponding position in the tray;

[0050] Step 103: The intelligent pairing software communicates with the OCR visual recognition device through a standard HTTP interface protocol, and receives the winding and rotor unique codes recognized by the OCR device. The data format is JSON format, and the information includes the OCR number, the measured product type, and the product unique code. The intelligent pairing software calls the HTML of the OCR visual recognition device software, and embeds the OCR real-time display result interface in the pairing software interface, providing a friendly and unified operation interface for the operator.

[0051] Step 104: The intelligent pairing software communicates with the sensor test system through a standard HTTP interface protocol and sends the code to the sensor test system;

[0052] Step 105: The sensor test system reads the code, selects the product model and test content, starts the test, completes the zero position search of the tested winding, output voltage, sum voltage test, phase, displacement, polarity, input impedance, output impedance and DC resistance test, and after the test is completed, returns the test results to the intelligent pairing software;

[0053] Step 106: The intelligent pairing software uses the built-in intelligent pairing algorithm to determine whether the voltage value at each angle is within the preset range, and performs weighted calculation on the upper and lower limits of each measurement to determine whether the winding matches the rotor. If it matches, the simulation model consistent with the rotor pairing tray is pushed on the interface, and the unique storage position of the rotor is highlighted, prompting the operator to put the rotor into the corresponding position in the tray; receive the release signal of the intelligent pairing tray position sensor to verify whether the rotor is placed in the correct position. If the calculation result is not a match, the intelligent pairing software will calculate a suitable size information according to the set algorithm and push it. The interface highlights the gear information of the newly pushed rotor. The operator takes a rotor in the gear and re-performs the pairing test until the match is successful, and the number of rotors on the rotor tray in the gear is reduced by 1.

[0054] Step 107: The intelligent pairing software controls the corresponding position indicator lights of the rotor pairing tray to light up to prevent errors in the process.

[0055] Step 108: There is no matching rotor in the rotor grading tray, prompting the operator to re-perform the rotor size measurement task;

[0056] The built-in algorithm of step 106 can be adapted to the matching rules of products of different models by configuring parameters.

[0061] Step 203: The device has an RS485 communication interface, which can quickly collect data and upload it to the host computer software;

[0062] Step 204: The host computer software receives the data, communicates with the intelligent pairing software through the network, uploads the data to the intelligent pairing software, and can push the corresponding position information on the interface through the software's built-in algorithm to achieve a process error prevention effect;

[0063] Step 205: Based on the rotor step tray position design, an abnormality determination is performed. If the final calculated measurement result exceeds the step tray position design range, it is considered as an abnormal product, and the software interface prompts to replace the rotor; if the measurement result is within the position range, the software pushes the corresponding position;

[0064] Step 206: The software stores the number of rotors in each gear position to realize intelligent push of subsequent processes. When the rotors in a certain gear position are full, it is prompted to replace the rotor grading tray.

[0065] Step 207: Design a rotor-graded tray to store rotors of different sizes. Divide the rotor size range into several gear areas, and design the layout of each gear on the tray according to the actual product size distribution.

[0067] Figure 3 is a schematic diagram of the control logic of the intelligent rotor pairing tray according to an embodiment of the present invention;

[0068] refer to Figure 3 The method in the present invention involves rotor pairing tray hardware and software design.

[0069] Step 301: Design an intelligent rotor pairing tray with a mark to store rotors that are successfully paired with windings, and each position on the tray has a unique mark and a prompt light;

[0070] Step 302: A sensor is installed in the tray position hole to detect the process of the rotor being put in and taken out;

[0071] Step 303: The tray can communicate with the host computer software through the RS232 serial port to exchange data;

[0075] refer to Figure 3 , establish a 3D model that matches the real object, combine the software's built-in rules and algorithms, realize dynamic interface push, and implement process error prevention.

[0076] Step 401: Establish a 3D model that matches the rotor step tray and the rotor pairing tray, and the position relationship between the model and the real object corresponds one to one;

[0077] Step 402: the software performs matching calculations according to the set rules and algorithms, retrieves the corresponding model according to the calculation results, and dynamically highlights the position information on the model;

[0078] Step 403: When the measured value exceeds the normal value range of the calculated result, a dialog box pops up on the software interface to prompt, and the user can choose to replace the test product or perform manual processing according to the prompt.

[0079] Step 404: Each time the stator winding is successfully matched with the rotor, the number of rotors on the corresponding gear of the rotor-grading tray is reduced by 1. When the number of rotors on the gear is insufficient, the software interface prompts to replace the tray.

[0080] The method includes:

[0081] Rotor identification and measurement process: The radial measurement of the rotor is completed by a laser diameter measuring device, which has a data communication interface and can upload the measurement results to the host computer;

[0084] Intelligent pairing software: Through software development, automatic data collection, equipment control, data processing, intelligent pairing, and result push are realized. The software is deployed on the server side, communicates with the host computer through the network, obtains the rotor size measured by the laser diameter gauge, obtains the final test result through background data calculation, and pushes the position information on the interface to prompt the operator to push the rotor to the corresponding gear of the rotor grading tray; through the OCR visual recognition device, the stator winding and the rotor unique code are identified, and the pairing software sends the code to the sensor test system. The sensor test system reads the code and performs the test. After the test, the test result is returned to the intelligent pairing software. The software calculates whether the stator winding and the rotor match according to the built-in intelligent pairing algorithm. If they match, the position information of the rotor pairing tray is pushed, and the control command is sent to the tray to light up the corresponding position indicator to prevent the operator from misplacing it. If the calculation result is not matched, the intelligent pairing software will calculate a suitable size information according to the set rules and push it. The operator takes a rotor in the newly pushed gear and re-performs the pairing test until the match is successful. There is no matching rotor in the rotor grading tray, prompting the operator to re-measure the rotor size;

[0085] Smart push interface: Build a 3D model that matches the real object, including a rotor grading tray and a smart rotor pairing tray. According to the measured rotor size, the interface highlights the rotor gear information, intuitively prompting the operator to put the rotor into the corresponding position; according to the software's built-in pairing algorithm, the interface pushes the smart rotor pairing tray light position or the rotor grading tray gear information to achieve process error prevention.

[0086] It should be noted that the above process operations can be applied in combination to different degrees. For the sake of simplicity, the implementation methods of various combinations are not described in detail. Those skilled in the art can flexibly adjust the order of the steps of the above method according to actual conditions, or perform operations in combination.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should all be covered within the protection scope of the present invention.
