Description

Technical Field

[0001] This utility model relates to the field of testing technology, and more specifically to a testing system for 5G communication modules. Background Technology

[0002] In recent years, in order to actively respond to the national 5G construction and promote 5G applications in the power sector, the rapid development of services such as distribution automation, electricity consumption information collection, user-side demand response, distributed energy access, and electric vehicle services has led to increasingly higher requirements for real-time, stable, reliable, and efficient communication. Based on 5G communication modules, 5G communication module products suitable for different power distribution terminal equipment have been developed to provide a secure, high-speed, reliable, and ubiquitous communication network for various services.

[0003] The 5G communication module is a series of modular products developed to meet the remote communication needs of power terminals. It is suitable for concentrators, dedicated transformer data acquisition terminals, three-phase meters, energy controllers, and new converged terminals, primarily providing them with 5G wireless public network communication services based on the operator's network, thus providing a reliable transmission channel for cloud-edge collaboration. The 5G channel of the 5G remote communication module can be used to connect the data acquisition and distribution systems. Data acquisition and distribution data are accessed via two independent 5G (APN+VPN) channels (belonging to the same operator or different operators) to the data acquisition master station and the distribution master station respectively.

[0004] With the rapid development of 5G technology, the quality testing of 5G communication modules has become a critical issue. The complexity and sophistication of 5G testing equipment result in high testing costs, including equipment, maintenance, and operational costs. 5G technology involves numerous new frequency bands, new technologies, and higher transmission rates, further increasing testing complexity. Due to the complexity of 5G communication modules, batch testing requires more time to ensure all functions and performance indicators meet standards. 5G testing consumes significant spectrum resources, which are inherently limited, especially in high-frequency bands, posing a challenge to batch testing. Traditional manual testing methods are inefficient and prone to errors, failing to meet the testing requirements of mass production of 5G modules. Utility Model Content

The voltage test command includes the identifier of any 5G communication module. The voltage identification device is configured to perform a voltage test on any 5G communication module upon receiving the voltage test command, and send the identifier of any 5G communication module and the corresponding test result to the host computer.

[0010] Optionally, each customized fixture is also equipped with a USB communication interface and a USB data interface on its exterior. The detection system also includes a data aggregation device for aggregating USB data between the host computer and each main control baseboard.

[0011] Optionally, the data aggregation device is a USB hub.

[0012] Optionally, the 5G interface includes: RGMII, IIC, and UART interfaces.

[0013] Optionally, each customized fixture is externally equipped with a power supply interface. The detection system further includes: a power module for converting the high-voltage AC power input into different low-voltage DC power, wherein the different low-voltage DC power includes at least 5V DC power; a power control board for dividing the 5V DC power into multiple groups of 5V DC power corresponding to the multiple customized fixtures; the main control baseboard is also equipped with a DC-DC converter group for converting the corresponding 5V DC power into 3.3V DC power to supply power to the microcontroller unit on the main control baseboard through the power supply interface; and converting the corresponding 5V DC power into 4V DC power to supply power to the 5G communication module.

[0014] Optionally, the detection system further includes: a fixing plate for fixing the 5G communication module on the main control base plate; and an antenna probe disposed on the fixing plate for extracting the radio frequency signal of the 5G communication module.

[0015] Optionally, the 5G interface includes a GPIO interface, and the host computer is also used to send power-on commands, power-off commands, or reset commands to each main control board. When each main control board receives the power-on command, the power-off command, or the reset command, it controls the corresponding 5G communication module through the GPIO interface.

[0016] Through the above technical solution, this utility model creatively designs multiple customized fixtures based on multiple 5G communication modules.

Each main control base plate tests the corresponding 5G communication module according to the functional test commands and sends the identifier of the corresponding 5G communication module and the test results back to the host computer. Therefore, the automated testing system provided by this utility model integrates the parallel testing of multiple modules into the same testing platform, enabling efficient and accurate batch automated testing, greatly improving testing efficiency, reducing labor costs, and can be widely applied in the mass production of 5G communication modules.

[0023] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0024] Figure 1 This is a structural diagram of a detection system for a 5G communication module provided in one embodiment of the present invention. Figure 1 As shown, the detection system may include: multiple custom fixtures (e.g., custom fixtures 10-1, 10-2, ... 10-n), an identification device 20, and a host computer 30.

[0025] The dimensions of the multiple customized fixtures (e.g., customized fixtures 10-1, 10-2, ... 10-n) are respectively adapted to the dimensions of multiple 5G communication modules (e.g., 5G communication modules 1-1, 1-2, ... 1-n). Figure 2 As shown, each custom fixture (e.g., custom fixture 10-1) has a main control base plate (e.g., main control base plate 2-1) fixed inside. Each main control base plate (e.g., main control base plate 2-1) is provided with a 5G interface (not shown, but the connection relationship between 5G communication module 1-1 and main control base plate 2-1 is indicated by a bidirectional arrow; the specific 5G interface is shown in the diagram below) for connection with the 5G communication module (e.g., 5G communication module 1-1). Figure 3In the diagram, the 5G communication module 1-1 and the main control baseboard interface 8 have a detailed 5G interface definition relationship, and a first probe (e.g., SIM card probe 3) for connecting to the SIM card of the 5G communication module (e.g., 5G communication module 1-1). Furthermore, each main control baseboard (e.g., main control baseboard 2-1) is also provided with a SIM card slot 120, such as... Figure 3 As shown.

[0026] The identification device 20 is used to identify the identifiers of the plurality of 5G communication modules and to send the identifiers of the plurality of 5G communication modules to the host computer 30.

[0027] The host computer 30 is used to send functional test commands to the main control baseboard (e.g., main control baseboard 2-1, 2-2, ... 2-n) corresponding to the plurality of 5G communication modules (e.g., 5G communication modules 1-1, 1-2, ... 1-n) according to the identifiers of the plurality of 5G communication modules.

[0028] Each main control baseboard (e.g., main control baseboard 2-1) is used to test the 5G communication module (e.g., 5G communication module 1-1) corresponding to each main control baseboard (e.g., main control baseboard 2-1) according to the function test instruction when it receives the function test instruction, and to send the identifier of the 5G communication module (e.g., 5G communication module 1-1) corresponding to each main control baseboard (e.g., main control baseboard 2-1) and the corresponding test results to the host computer 30.

[0029] The identification device 20 can be a QR code scanner 25, such as... Figure 2 As shown. In the specific implementation process, one or more QR code scanners 25 can be used. The host computer 30 is used for communication and control with the embedded system. The software is developed and run on the PC, providing a user-friendly human-machine interface. It mainly realizes functions such as data acquisition, system control, user permission configuration management, data analysis and processing, communication management, updates and maintenance, etc. For example, the physical layer communicates and interacts with the automation system through the USB interface. The host computer simulates the terminal device's command operation on the module under test, and queries the module's network status, signal strength, network type and other information through corresponding AT commands.

[0030] like Figure 2As shown, taking a testing system comprising four custom fixtures as an example, this embodiment provides a four-station automated testing system for 5G communication modules. The system includes a functional testing unit 1000 (which includes custom fixtures 10-1, 10-2, 10-3, and 10-4), an identification device 20, and a host computer 30, among other main components. The functional testing unit 1000 mainly includes four testing stations. Each station has a custom fixture designed according to the dimensions of the module under test (5G communication module). A main control base plate 2-1 is fixed inside the custom fixture. Figure 2 or Figure 3 As shown. The main control baseboard is designed with an interface for a general 5G communication module, which is responsible for the electrical connection of the 5G communication module under test. The main control baseboard is also designed with a physical probe structure, which connects the SIM card signal of the 5G module under test to the main control baseboard through the probe. 5G communication can be performed when the SIM card signal is connected to the main station network, and the corresponding test process can be performed at this time.

[0031] Using a QR code scanner 25, the image signal processing function of the scanner is utilized to scan the QR codes of the tested modules (i.e., 5G communication modules) at the four workstations. Each QR code identifies the module's product ID (i.e., module ID) and model number. The scanner transmits the scanned data to the host computer 30 via USB communication, recording the information for each tested module (i.e., 5G communication module). The host computer 30 identifies the USB communication port of each workstation through mapping and binds it to the previously scanned module ID, ensuring a one-to-one correspondence between the tested module and the communication port. The host computer 30 can send functional test commands to multiple main control boards. The main control boards test the corresponding tested modules according to the specific content of the functional test commands and upload the identifiers of the corresponding tested modules and the corresponding test results to the host computer.

[0032] The functional test instructions include one or more of the following: reading software version and module model, querying SIM card status, querying 5G registration information, querying 5G attachment information, querying 5G network standard, querying 5G signal strength, performing read / write tests on USB communication function, performing read / write tests on UART communication function, performing read / write tests on IIC communication function, performing read / write tests on Ethernet communication function, and testing BeiDou positioning communication function, etc.

[0033] In one embodiment, the detection system further includes an LED identification device. The LED identification device includes: multiple LED detection optical fibers, respectively fixed at the positions of the indicator lights of the multiple 5G communication modules; and an LED detector, used to identify the color and status of the indicator lights of the multiple 5G communication modules, and to send the identifiers and corresponding colors and statuses of the multiple 5G communication modules to the host computer.

[0034] The LED identification device is an LED detector 40, such as... Figure 2 As shown.

[0035] like Figure 2 As shown, the LED detector 40 detects the status of the indicator lights on each tested module (e.g., 5G communication module 1-1, 5G communication module 1-2, 5G communication module 1-3, 5G communication module 1-4). The LED detector 40 uses LED optical fiber transmission to fix each LED detection fiber (e.g., LED detection fiber 45-1, LED detection fiber 45-2, LED detection fiber 45-3, LED detection fiber 45-4) to the corresponding position of the indicator lights on each tested module (e.g., 5G communication module 1-1, 5G communication module 1-2, 5G communication module 1-3, 5G communication module 1-4). The LED detector processes the optical signals transmitted through the optical fibers to identify the status of the indicator lights on each tested module. For example, the LED detector 40 reports the processed data (including the identifiers of each tested module and the corresponding indicator light status) to the host computer 30 via USB communication. The host computer 30 analyzes and judges the reported data, thereby realizing the LED identification function.

[0036] In one embodiment, the detection system further includes a voltage identification device connected to a voltage test point on each 5G communication module via a second probe. The host computer is further configured to send a voltage test command to the voltage identification device upon receiving the identifier of any 5G communication module and upon the test result indicating that the model and software version of any 5G communication module are correct. The voltage test command includes the identifier of the any 5G communication module. Upon receiving the voltage test command, the voltage identification device performs a voltage test on the any 5G communication module and sends the identifier of the any 5G communication module and the corresponding test result to the host computer.

[0037] The voltage identification device may be a voltage detector 50.

[0038] like Figure 2As shown, upon receiving the identifier of any 5G communication module (e.g., 5G communication module 1-1) and confirming that the model and software version of the 5G communication module (e.g., 5G communication module 1-1) are correct, the voltage tester 50 detects the power supply status of the 5G communication module (e.g., 5G communication module 1-1) (i.e., performs a voltage test). During the hardware design process, internal power supply voltage test points are reserved on the PCB board of each 5G communication module. The automated testing system connects the voltage test points of each tested module (e.g., 5G communication module 1-1, 5G communication module 1-2, 5G communication module 1-3, 5G communication module 1-4) to the voltage tester 50 using a physical probe structure. The voltage tester 50 processes electrical signals, for example, by reporting the identifier of each tested module and the corresponding measured voltage value to the host computer 30 via USB communication. The host computer 30 performs data analysis and judgment, thereby realizing the voltage detection function.

[0039] In one embodiment, each customized fixture is also provided with a USB communication interface and a USB data interface on its exterior. The detection system also includes a data aggregation device for aggregating USB data between the host computer and each main control baseboard.

[0040] The data aggregation device is a USB hub 60, such as... Figure 2 As shown.

[0041] like Figure 3 As shown, the external electrical interfaces of the custom fixture (e.g., custom fixture 10-1) include a USB communication interface 5 and a USB data interface 6. The physical layer communicates and interacts with the automation system through the USB interface. The data aggregation device can be a USB hub 60, which increases the number of USB interfaces of the internal devices of the automation system, enabling the host computer to connect more USB devices simultaneously and perform data transmission and system control functions at the same time.

[0042] In one embodiment, the 5G interface includes: RGMII, IIC, and UART interfaces.

[0043] The module under test uses 5G wireless communication for uplink and supports RGMII, IIC, UART, and USB interfaces for downlink communication. To accommodate different 5G communication module interface types for various terminal devices, and to ensure that this automated testing system is not limited to a single 5G communication module product, in this embodiment, 5G interfaces such as RGMII, IIC, and UART are provided on the main control board. Figure 3 As shown. The downlink interface connects to the microcontroller unit (MCU) on the main control board for data processing. The MCU uses a UART-to-USB converter (e.g., via...) Figure 3The UART-to-USB chip in the module reports information to the host computer software; the module under test supports USB communication, so the USB data interface of the module under test can directly report to the host computer; the host computer identifies the USB communication port of each workstation through mapping and binds it with the previously scanned module ID to ensure that the module under test corresponds one-to-one with the communication port. The host computer software can send AT commands to query the working status and information of the module under test, realizing the software query and control of the module under test by the host computer.

[0044] Figure 3 The main control board interface 8 may include 5G interfaces such as RGMII interface, IIC interface, UART interface, and GPIO interface.

[0045] In one embodiment, each custom fixture is externally provided with a power supply interface 7, such as... Figure 3 As shown. Figure 2 As shown, the detection system further includes: a power module 70, used to convert the high-voltage AC power input into different low-voltage DC power, wherein the different low-voltage DC power includes at least 5V DC power; and a power control board 80, used to divide the 5V DC power into multiple groups of 5V corresponding to the multiple customized fixtures. The main control baseboard is also equipped with a DC-DC converter group, including: a first DC-DC converter 90, used to convert the corresponding 5V DC power into 3.3V DC power to supply power to the microcontroller unit on the main control baseboard through the power supply interface; and a second DC-DC converter 95, used to convert the corresponding 5V DC power into 4V DC power to supply power to the 5G communication module, such as... Figure 3 As shown.

[0046] The power module 70 is a crucial component responsible for powering the automation system. The system input is 220V AC mains power, supplying power to the overall system, voltage tester, and PC host. The system includes an AC-to-DC power module that converts the 220V AC power into 5V, 12V, and 24V DC voltages required by each functional unit. The 12V DC voltage powers the USB hub, and the 24V DC voltage powers the LED detector. The 5V DC voltage passes through a power control board 80, which then powers the functional test units at the four workstations. The power control board 80 incorporates an embedded system and four relays. For example, the host computer software sends commands to the embedded system in the power control board 80 via USB communication to control the relays' on / off states, thus powering on and off the functional test units at each workstation. Users can configure the host computer software to enable parallel power-on testing of multiple modules. This flexible system configuration significantly shortens testing time and improves testing efficiency. The power control board 80 is used to divide a 5V DC power supply into four 5V DC power supplies, which supply power to the main control baseboards 2-1, 2-2, 2-3, and 2-4 respectively. The power control board is controlled by the host computer and can freely control the power supply to the main control baseboards 2-1, 2-2, 2-3, and 2-4 to ensure that each workstation works independently without affecting each other.

[0047] The 5V power supply is converted into 4V and 3.3V by the DC-DC converter group (first DC-DC converter 90 and second DC-DC converter 95) on the main control board. These 4V and 3.3V power supplies respectively to the module under test (e.g., 5G communication module 1-1) and the microcontroller unit (MCU) 4 on the main control board (e.g., main control board 2-1). Figure 3 As shown.

[0048] In one embodiment, the detection system further includes: a fixing plate (not shown) for fixing the 5G communication module to the main control base plate; and antenna probes (e.g., antenna probe 90-1, antenna probe 90-2, antenna probe 90-3, antenna probe 90-4), disposed on the fixing plate, for extracting the radio frequency signals of the 5G communication module, such as... Figure 2 As shown.

[0049] When the module under test (DUT) is placed in the custom fixture, pressing down the handle controls the fixing plate to secure the DUT onto the main control base plate at the test station. The fixing plate is equipped with antenna probes (e.g., antenna probes 90-1, 90-2, 90-3, and 90-4). The RF signal from the DUT is guided to the outside of the system via these probes, and then connected to external 5G RF antennas (e.g., 5G antennas 100-1, 100-2, 100-3, and 100-4) and BeiDou positioning antennas (e.g., BeiDou antennas 110-1, 110-2, 110-3, and 110-4) to achieve long-distance wireless communication. Figure 2 As shown.

[0050] In one embodiment, the 5G interface further includes a GPIO interface. The host computer is also used to send power-on commands, power-off commands, or reset commands to each main control board. Upon receiving the power-on command, the power-off command, or the reset command, each main control board controls the corresponding 5G communication module through the GPIO interface.

[0051] Upon receiving a power-on command from the host computer, the microcontroller unit (MCU) 4 on the main control board 2-1 can use its own GPIO resources (i.e., GPIO interface) to perform power-on software control on the module under test. Simultaneously, the analog signals output by the module under test can also be detected and processed through the MCU's GPIO interface. In other words, the GPIO interface can be configured by software to have both input and output states. The detection GPIO interface receives electrical signals from the 5G communication module 1-1, which are transmitted to the MCU for processing; the control GPIO interface receives electrical signals from the MCU, which are transmitted to the 5G communication module for control. For power-off or reset commands, the relevant operations for the power-on command described above can be followed; specific details will not be elaborated here.

[0052] When using this 5G communication module testing system, it is necessary to pre-configure various parameters of the host computer software, select the hardware version, production model and manufacturer information of the 5G communication module to be tested, and set the threshold of each test item according to the testing standards and technical specifications so that the system can analyze and judge based on these parameters.

[0053] This utility model adopts a professional measurement and control hardware design, combined with human-computer interaction technology and the common interaction form in the automation industry; the detection method is combined with the host computer, and the test process and index range can be customized and configured using independent administrator privileges, so as to realize the simultaneous testing of multiple modules, and complete the judgment of whether the module is qualified and the generation of test reports.

[0054] like Figure 4As shown, the testing method flow of the automated testing system for 5G communication modules (hereinafter referred to as the 5G module under test) is as follows.

[0055] 1. Turn on the system power and insert the 5G module to be tested.

[0056] Turn on the system power and place the four 5G modules under test into their respective test stations; press the pneumatic switch to press the mounting plate onto the 5G modules under test.

[0057] 2. Scan the 5G module's QR code and report the module information.

[0058] Using a QR code scanner, the QR codes of the 5G modules under test are sequentially scanned, and the QR code information is reported to the host computer. In this embodiment, the testing system is equipped with only one scanner, and the QR codes of the modules need to be scanned sequentially. The modules are only tested after all the QR code information has been entered into the system. The testing process is parallel.

[0059] 3. Power the 5G module.

[0060] The host computer sends commands to the power control board to sequentially power the 5G modules under test.

[0061] 4. Read the model and software version information of the 5G module under test.

[0062] Commands are sent from the host computer to read the software version and module model of the 5G module under test in sequence.

[0063] 5. Verify that the model number and software version are correct.

[0064] If yes, proceed to step 6; otherwise, proceed to step 2.

[0065] 6. Test the internal operating voltage of the 5G module and return the test value.

[0066] The voltage detector sequentially detects the internal operating voltage of the 5G module under test and reports the voltage value to the host computer software.

[0067] 7. Test the power-on / off and reset functions of the 5G module and return the test results.

[0068] Commands are sent from the host computer to perform power-on and power-off function tests on the 5G modules under test in sequence; commands are also sent from the host computer to perform reset function tests on the 5G modules under test in sequence.

[0069] 8. Test the indicator light color and status and return the test results.

[0070] The LED recognition unit sequentially detects the color and status of the indicator lights on the 5G module under test, and reports the detection results to the host computer.

[0071] 9. Test the 5G network functionality and return the test results.

[0072] The host computer sends commands to query the SIM card status of the 5G module under test in sequence, and reports the query results to the host computer.

[0073] 10. Test the 5G module's communication function and return the test results.

[0074] Commands are sent from the host computer to sequentially query the 5G registration information, 5G attachment information, 5G network standard, 5G signal strength, USB communication function, UART communication function, IIC communication function, and Ethernet communication function of the 5G module under test. Any of the above communication function tests are performed on the 5G module under test.

[0075] 11. Test the BeiDou positioning function and return the test results.

[0076] Commands were sent from the host computer to test the BeiDou positioning and communication functions of the 5G module under test in sequence.

[0077] 12. Determine whether the module under test has passed the above test items.

[0078] The host computer software compares the returned test results to determine and output whether the 5G module under test at each workstation has passed the test: if yes, proceed to step 13; otherwise, proceed to step 14.

[0079] 13. Display PASS, listing the test items and test data.

[0080] The host computer will evaluate the test results for each workstation separately. Since the system performs parallel testing on the modules, if one module fails, it will not affect the normal testing of other modules. For example, if the system has four test workstations, the host computer will have four windows to display whether each module has passed or failed.

[0081] 14. Display FAIL, list the test items and test data, and list the reasons for the failure.

[0082] 15. Save the test results.

[0083] The host computer saves the test results and records them in an Excel spreadsheet.

[0084] After all tests were completed, the power was cut off at each workstation via the host computer, the pneumatic fixing plate was raised, and the 5G communication module under test was replaced.
