[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0021] According to an embodiment of the present invention, an embodiment of a wireless charging device detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0022] In this embodiment, a wireless charging device detection method is provided, which is applied to a wireless charging device detection system. The wireless charging device detection system is used to detect wireless charging devices assembled in a wireless charging device production system. The wireless charging device detection system is connected to the wireless charging device to be detected through a signal line and a power line. The wireless charging device detection system is pre-configured with test operation programs corresponding to various functions of the wireless charging device; communication with the wireless charging device to be detected can be achieved through the signal line, and power can be supplied to the transmitting coil of the wireless charging device to be detected through the power line; in the embodiment of the present application, the wireless charging device detection system is connected to the wireless charging device production system for detecting the wireless charging device production system. The produced wireless charging equipment is tested; taking the on-board wireless charging equipment as an example, after the on-board wireless charging equipment production system completes the assembly of the on-board wireless charging equipment at the front end, the wireless charging equipment detection system and the wireless charging equipment production system can be connected through the guide rail, and the assembled on-board wireless charging equipment is transferred to the wireless charging equipment detection system through the automatic transportation guide rail. In the embodiment of the present application, the wireless charging equipment detection system can include a robotic arm (such as an XYZ robotic arm), which can place the on-board wireless charging equipment transferred to the wireless charging equipment detection link on the test bench through the control program, and automatically crimp the corresponding cables (such as signal lines and power lines, etc.), and start the automated testing process of the wireless charging equipment. Figure 1 As shown, the process includes the following steps:

[0023] Step 101: In response to receiving a test instruction for any target function of a wireless charging device to be tested, triggering the execution of a corresponding test operation program to perform a corresponding target function test operation on the wireless charging device to be tested;

[0024] For example, the wireless charging device detection system in the embodiment of the present application can pre-integrate a variety of test programs for testing the functions of the wireless charging device, and generate a corresponding test instruction for the target function to be tested based on the received selection operation of any function to be tested, so that the wireless charging device to be tested executes the corresponding function to be tested under the corresponding test instruction. Specifically, it can receive upper-layer UI commands, parse and package them through software, and transmit them through the UDS diagnostic service of the CAN module and the CAN / CANFD interface to achieve interaction with the wireless charging device. Among them, the interaction process can use many UDS diagnostic services, such as "10 service", "22 service", "27 service", "2E service", etc.

[0025] In an embodiment of the present application, a wireless charging device detection system may include an electronic barcode scanner configured to scan a QR code on a production label on a wireless charging device to obtain target device information of the wireless charging device contained in the QR code. This target device information may include, but is not limited to, the device's production date, process information, and device number. Each wireless charging device assembled in the wireless charging device production system is assigned a unique QR code. The production label may be manufactured on a PCBA during the manufacturing process. Specifically, an image acquisition device may be provided within the wireless charging device detection system. When a new wireless charging device to be detected is introduced into the image acquisition area of ​​the image acquisition device, the electronic barcode scanner is controlled to scan the QR code information of the wireless charging device to be detected. Specifically, the image acquisition device may determine the location of the QR code on the wireless charging device to be detected, and then control the electronic barcode scanner to move to an appropriate position to perform the QR code scanning operation. The present embodiment does not limit the specific structure and scanning method of the barcode scanning system. Persons skilled in the art may design the system based on actual needs, as long as the QR code information of the wireless charging device to be detected can be obtained. The target device information of the wireless charging device to be detected obtained by scanning is sent to the processor of the wireless charging detection system to verify the target device information. The specific verification types include the legality and format accuracy of the target device information to be written, and illegal information is intercepted. The target device information with correct format and legality can be written into the electronic control unit (ECU) of the wireless charging device through the CAN diagnostic protocol, so that in the subsequent functional test process, the wireless charging device to be detected can carry information such as the device ID for test result feedback and facilitate the subsequent upgrade of the device firmware based on the written device parameters.

[0026] Step 102 : determining a test result of a target function of the wireless charging device to be tested based on the received execution result of the current test of the wireless charging device to be tested.

[0027] For example, when an overvoltage test is performed on the wireless charging device to be tested, overvoltage charging is performed on the wireless charging device to be tested through the power line. When the electronic control unit in the wireless charging device to be tested feeds back an overvoltage signal, it indicates that the overvoltage detection function test of the wireless charging device to be tested has passed.

[0028] The wireless charging device detection method provided by the embodiment of the present invention is applied to a wireless charging device detection system connected to a wireless charging device to be detected through a signal line and a power line. The wireless charging device detection system is pre-configured with test operation programs corresponding to multiple functions of the wireless charging device. When a test instruction for any target function of the wireless charging device to be detected is received, the corresponding test operation program is triggered to execute the corresponding target function test operation on the wireless charging device to be detected. Whether the test result of the target function of the wireless charging device to be detected passes is determined based on the execution result of the wireless charging device to be detected for the current test, thereby realizing automated testing of the wireless charging devices on the production line. For the wireless charging devices to be detected on the production line, product quality problems can be discovered in a timely manner, which facilitates timely debugging and ensures the safe use of the wireless charging devices. In addition, the entire process does not require manual participation, thereby improving production efficiency and reducing the risk of manual operation failure.

[0029] As an optional implementation of an embodiment of the present invention, a wireless charging device detection system includes: a host computer, wherein a display interface of the host computer displays multiple target function interaction modules to be tested; the method also includes: in response to receiving a touch operation on any target function interaction module to be tested, generating a test instruction for the corresponding target function.

[0030] For example, by setting up the host computer, the test personnel can select the test tasks that need to be performed on the wireless charging device for the target function test, or complete the test tasks of the corresponding functions to be tested in sequence according to the preset test sequence after the QR code information is written. Specifically, manual test controls and automatic test controls can be set on the interactive interface, and the manual test program or the automatic test program can be entered by selection. In the manual test program, the interactive controls of the target function to be tested can be manually touched, and then the test instructions of the corresponding target function are generated; for the automatic test program, the corresponding target function interactive modules can be automatically triggered in sequence according to the preset test sequence, and then the corresponding test instructions are generated.

[0031] As an optional implementation of the embodiment of the present invention, the target function includes: a Q value calibration function of the wireless charging device; the method further includes:

[0032] Step a1: upon receiving a test instruction for the Q-value calibration function of the wireless charging device, sending a mode switching instruction to the wireless charging device to be tested according to the target protocol through a preset communication module, so that the wireless charging device to be tested enters an extended diagnostic session mode;

[0033] For example, in the embodiment of the present application, the preset communication module can be a CAN communication module, and the target protocol can be a unified diagnostic protocol (UDS). When the test instruction corresponding to the Q value calibration function is issued by the host computer software, the CAN communication module issues a switch session to "10 03" instruction to enter the extended session mode.

[0034] Step a2, responding to the authority authentication operation of the parameter calibration operation of the wireless charging device to be detected;

[0035] For example, the cryptographic seed of the ECU of the wireless charging device is obtained through the "27 service" of UDS, and after the cryptographic seed is converted into a key, the key is sent to the ECU of the wireless charging device through the "27 service" of UDS. When the key is verified by the ECU of the wireless charging device, it indicates that the authority authentication of the parameter calibration operation of the wireless charging device to be tested is passed.

[0036] Step a3: When the authority authentication is passed, a Q value calibration instruction is sent to the wireless charging device to be detected, so that the wireless charging device to be detected responds to the Q value calibration operation;

[0037] For example, when the authority authentication is passed, a Q-value calibration instruction is sent to the ECU of the wireless charging device to be detected through the "31 service" of the UDS to start the Q-value calibration function of the wireless charging device to be detected, so that the wireless charging device to be detected responds to the Q-value calibration operation and will feedback the calibration execution result to the wireless charging device detection system after executing the Q-value calibration.

[0038] Step a4, responding to the receiving operation of the Q value calibration execution result;

[0039] Step a5: Determine the Q-value calibration function test result of the wireless charging device to be tested based on the Q-value calibration result. For example, if the feedback calibration result is a positive response, the calibration function test is determined to have passed; if the Q-value calibration result is a negative response, the calibration function test is determined to have failed.

[0040] As an optional implementation manner of an embodiment of the present invention, the method further includes: in response to receiving an acquisition instruction for the calibrated transmitting coil Q value and the corresponding temperature value, sending the acquisition instruction to the corresponding wireless charging device to be detected according to the identification information contained in the acquisition instruction; based on the association relationship between the temperature value and the Q value established during calibration and the currently acquired temperature value, correcting the acquired calibrated transmitting coil Q value; when the corrected transmitting coil Q value is within a preset threshold range, determining that the Q value calibration function test has passed; when the corrected transmitting coil Q value is not within the preset threshold range, determining that the Q value calibration function test has failed.

[0041] For example, after the calibration function test is performed on the wireless charging device to be tested, the calibration result is further verified, specifically to obtain the Q value of the transmitting coil and the corresponding temperature value of the calibrated wireless charging device to be tested. Specifically, the host computer can send an acquisition instruction for the Q value of the transmitting coil and the corresponding temperature value after calibration. When the acquisition instruction for the Q value of the transmitting coil and the corresponding temperature value after calibration is received, the CAN communication module sends a switching session to the "10 01 instruction", and sends the acquisition instruction to the corresponding wireless charging device to be tested according to the identification information contained in the acquisition instruction, so that the ECU of the wireless charging device to be tested sends the current transmitting coil Q value and the corresponding temperature value according to the acquisition instruction; the detection system can read the corresponding device ID information through the "22 service" of the UDS, and parse the corresponding transmitting coil Q value and temperature value from the returned positive response data according to the information defined by the CAN matrix. Based on the correlation between the temperature value and the Q value established during calibration, the currently acquired Q value of the transmitting coil is corrected to prevent the temperature from affecting the acquisition result of the transmitting coil Q value. When the corrected Q value of the transmitting coil is within a preset threshold range, it is determined that the Q value calibration function test has passed; when the corrected Q value of the transmitting coil is not within the preset threshold range, it is determined that the Q value calibration function test has failed. The embodiments of the present application do not limit the preset threshold range, and those skilled in the art can determine it according to actual needs.

[0042] As an optional implementation of the embodiment of the present invention, the target functions further include: a charging function of a target transmitting coil corresponding to the wireless charging device to be detected, a foreign object detection function of the wireless charging device to be detected, and a forgotten reminder function of the wireless charging receiving device; the method further includes:

[0043] When a test instruction corresponding to the charging function of the target transmitting coil is received, the wireless charging receiving device is placed in the charging area corresponding to the target transmitting coil; a network wake-up instruction and a charging function start instruction are sent to the wireless charging device to be tested, so that the wireless charging device to be tested responds to the charging operation of the wireless charging receiving device; when a charging status signal is received from the wireless charging device to be tested, the charging function test of the target transmitting coil is determined to have passed, otherwise it is determined to have failed;

[0044] For example, in the embodiments of the present application, the wireless charging receiving device can be a simulated wireless charging receiver that can simulate interactive communication between a mobile phone and a wireless charging device. Upon receiving a test instruction corresponding to the charging function of a target transmitting coil, the robot arm can be controlled to place the wireless charging receiving device within the charging area corresponding to the target transmitting coil, specifically at an appropriate height above the target transmitting coil, to simulate the charging process. A network wake-up instruction and a charging function activation instruction are sent to the wireless charging device to be tested via the CAN communication module. The network wake-up instruction awakens the ECU in a low-power sleep state. Upon receiving the charging function activation instruction, the ECU actively initiates interaction with the wireless charging receiving device to complete the charging process. When the charging process stabilizes, a charging status signal is sent to the CAN communication module. Upon receiving the charging status signal on the CAN bus, the detection system determines that the charging function test of the target transmitting coil has passed; otherwise, the detection system determines that the charging function test of the target transmitting coil has failed. In the embodiments of the present application, the number of target transmitting coils can be one or more, and those skilled in the art can select the desired one based on actual needs. During the charging process, the charging voltage and charging current of the wireless charging device can be collected and recorded by an external measuring device and compared with voltage and current thresholds, respectively, to test the charging process of the wireless charging device. The corresponding test results can be displayed in the corresponding test items on the host computer and uploaded to the MES system.

[0045] When a test instruction corresponding to the foreign object detection function is received, a metal foreign object is placed in the charging area between the wireless charging device to be tested and the wireless charging receiving device; a network wake-up instruction and a charging function start instruction are sent to the wireless charging device to be tested, so that the wireless charging device to be tested responds to the charging operation of the wireless charging receiving device; when a foreign object detection status signal is received from the wireless charging device to be tested, the foreign object detection function test is determined to have passed; otherwise, it is determined to have failed;

[0046] For example, after the host computer software issues a test instruction corresponding to the foreign object detection function (FOD), a metal foreign object can be placed in the charging area between the wireless charging device to be tested and the wireless charging receiving device through a robotic arm to simulate a charging scenario in which a metal foreign object is present; a network wake-up instruction and a charging function start instruction are issued through the CAN communication module. When the ECU of the wireless charging device to be tested receives the network wake-up instruction and the charging function start instruction, it will actively initiate the charging process and interact with the wireless charging receiving device; when the wireless charging device to be tested detects a metal foreign object, it sends a FOD status signal to the CAN bus. When the host computer receives the FOD status signal on the CAN bus, it indicates that the test has passed; if the FOD status signal cannot be detected, the test of the foreign object detection function has failed.

[0047] When a test instruction corresponding to the forgotten reminder function of the wireless charging receiving device is received, the wireless charging receiving device is placed in the charging area corresponding to the wireless charging device to be tested; a network wake-up instruction and a charging function start instruction are sent to the wireless charging device to be tested, so that the wireless charging device to be tested responds to the charging operation of the wireless charging receiving device according to the charging function start instruction; a door closing instruction is sent to the wireless charging device to be tested, so that the wireless charging device to be tested triggers the generation of a forgotten reminder status signal of the wireless charging receiving device according to the door closing instruction when it is in the charging state; when the forgotten reminder status signal sent by the wireless charging device to be tested is received, it is determined that the forgotten reminder function test of the wireless charging receiving device has passed, otherwise, it is determined to have failed.

[0048] For example, after the upper computer software issues a test instruction to test the forgotten reminder function of the wireless charging receiving device (such as a mobile phone), it can control the robotic arm to place the wireless charging receiving device in the charging area corresponding to the wireless charging device to be tested, such as moving it to an appropriate height above the wireless charging device; and send a network wake-up instruction and a charging function start instruction through the CAN communication module. When the ECU of the wireless charging device to be tested receives the network wake-up instruction and the charging function start instruction, it will actively initiate the charging process and interact with the wireless charging receiving device. When it detects that the mobile phone is in the charging state and receives the door closing instruction, it triggers the sending of a forgotten reminder status signal of the wireless charging receiving device to the CAN bus. When the upper computer receives the forgotten reminder status signal of the wireless charging receiving device on the CAN bus, it determines that the function test has passed; if the forgotten reminder status signal of the wireless charging receiving device is not received, the function test has failed.

[0049] As an optional implementation manner of an embodiment of the present invention, the target function also includes: an overvoltage protection function and an undervoltage protection function of the wireless charging device to be tested; the method also includes: when receiving a test instruction corresponding to the overvoltage protection function of the wireless charging device to be tested, adjusting the power supply voltage of the wireless charging device to be tested to the overvoltage voltage value; sending a network wake-up instruction and a charging function start instruction to the wireless charging device to be tested; when receiving an overvoltage protection signal sent by the wireless charging device to be tested, determining that the overvoltage protection function test has passed, otherwise, determining that it has failed.

[0050] For example, the host computer software issues a test command for the overvoltage protection function, adjusts the supply voltage of the wireless charging device to the overvoltage value (e.g., 16.5V), and issues a network wake-up command and a charging function enable command via the CAN communication module. When the ECU of the wireless charging device detects an overvoltage, it sends an overvoltage protection signal to the CAN bus. If the host computer receives the overvoltage protection signal on the CAN bus, it determines that the overvoltage protection function test has passed; otherwise, it is determined to have failed.

[0051] When a test instruction corresponding to the undervoltage protection function of the wireless charging device to be tested is received, the power supply voltage of the wireless charging device to be tested is adjusted to the undervoltage voltage value; a network wake-up instruction and a charging function start instruction are sent to the wireless charging device to be tested; when an undervoltage protection signal is received from the wireless charging device to be tested, the undervoltage protection function test is determined to have passed, otherwise, it is determined to have failed.

[0052] For example, the host computer software issues a test command corresponding to the undervoltage protection function, adjusts the supply voltage of the wireless charging device to the undervoltage value (e.g., 8.5V), issues a network wake-up command and a charging function enable command via the CAN communication module, and the ECU of the wireless charging device to be tested sends an undervoltage protection signal to the CAN bus. If the host computer receives the undervoltage protection signal on the CAN bus, it determines that the overvoltage protection function test has passed; otherwise, it is determined to have failed.

[0053] As an optional implementation of an embodiment of the present invention, the method further includes: uploading the test results to a host computer and displaying them on a target display interface; uploading the test results to a manufacturing execution system. For example, by uploading the test results to the host computer and displaying them on a target display interface, it is convenient for testers to view the test results; and uploading the test results to a manufacturing execution system (EMS) facilitates tracing abnormal problems based on the device identification of the wireless charging device to be tested, as well as statistical analysis and good product judgment of the product. If all test items pass the test and the test results conform to the distribution pattern of products in the same batch, the product is judged to be good.

[0054] As a specific embodiment of the present application, the wireless charging device detection system provided in the embodiment of the present application can be composed of a voltage-stabilized power supply, a production label, an electronic barcode scanner, an ECU communication module, a wireless charging device, and a host computer; a QR code containing the production date, process, device number, and other information of the device is set on the production label in the system, and a unique QR code information is entered for each assembly device. The electronic barcode scanner is connected to the PC for automatically identifying the QR code information of the product. The ECU communication module is connected to the CAN / CANFD communication interface of the wireless charging device for information interaction with the wireless charging device. The interaction process can adopt the standard on-board CAN / CANFD standard protocol and UDS diagnostic protocol; the host computer can be used to implement the logical functions of the entire system. The system integrates the drivers and protocols of each component and can initiate corresponding test tasks according to the set automation process, record and verify the corresponding test results, and upload the test results to the factory's MES system for easy tracking later. The wireless charging device detection system is connected to the factory's MES system, adopts a network interface, and uses the factory's unified communication protocol.

[0055] The log module of the wireless charging device detection system is used to record the log information of the system working process, such as the status of the device, the results of the test items, the temperature of the tested device, important device information (such as device number, software version number, hardware version number, production date, etc.), etc., to facilitate subsequent information backtracking and bug analysis. In the automatic function, after the QR code information is scanned and entered, the corresponding steps will be automatically executed in sequence. In the manual function, click the corresponding button of the step to perform the operation. The result of the operation will be displayed on the interactive interface and uploaded to the MES system at the same time. By switching the software mode, you can choose to enter production information, check the entry results, OTA upgrade and Q value calibration in an automatic or manual way. In the embodiment of the present application, in addition to obtaining the information by scanning the QR code with a scanner, the written information of the wireless charging device can also include the configuration information of the wireless charging device or information automatically generated according to the rules. When the writing information is ready, the host computer initiates the writing information instruction, the CAN communication module issues the switching session to the "10 03 instruction", obtains the seed of the wireless charging device ECU through the "27 service", and converts the seed into a key, and sends the key to the ECU of the wireless charging device through the "27 service". After the key is authenticated by the wireless charging device ECU, the host computer writes information to the corresponding ID via the "2E Service." This information may include the wireless charging device's production date, shift, software version, hardware version, bootloader version, and more; it may also include manufacturer information. Once the information is written, if a positive response is received from the wireless charging device, the write is successful; if a negative response is received, the write fails. The corresponding test results are displayed within the host computer's test items and uploaded to the MES system. The verification process for the wireless charging device's written information includes the following: After the host computer initiates approval, the CAN communication module issues a "10 01" session switch command. The host computer reads the information from the corresponding ID via the "22 Service." After parsing the result according to the CAN matrix definition, it compares it with the verification information. If the information matches, verification passes; if not, verification fails. If all test results for the corresponding test items in the test function pass and the test values ​​meet the data distribution requirements for a production batch (such as yield rate and CPK), the wireless charging device under inspection is deemed conforming.

[0056] As an optional implementation of an embodiment of the present invention, the method further includes: a sleep and wake-up function test: After the wireless charging device to be tested is powered on, the wireless charging device is placed in a sleep state and the sleep current of the wireless charging device is tested. If the current reading is within the threshold range, the sleep current test passes; otherwise, the sleep current test fails. If the sleep test passes, a wake-up command is sent via the CAN bus. If the host CAN bus device can receive the device status information, the wake-up test passes; otherwise, the wake-up test fails. The corresponding test results are displayed in the host computer test item and uploaded to the MES system.
