Description

Technical Field

[0001] The present invention relates to the technical field of production testing of frame type equipment in the industrial field, and in particular to a method for batch production testing of frame type equipment. The method can significantly improve production efficiency, ensure the quality and performance of boards, and is suitable for large-scale manufacturing environments. Background Art

[0002] The current frame-type integrated equipment has a variety of functions, including data exchange, power supply, management, data processing, and voice call units. The traditional mass production test process first tests the single board of each functional unit, and then assembles these boards into the frame for a second round of whole machine testing. In this process, each unit needs to go through steps such as program burning, hardware testing, software testing, and recording test results. Not only is the process complicated and inefficient, but it also requires a lot of manpower. The test of each unit requires a dedicated test station, which limits production efficiency. It usually takes a whole day to complete the test of a frame. In addition, different tooling is required for testing different boards and models, which not only increases costs but also reduces compatibility. At the same time, there are certain problems with the accuracy and fault tolerance of manual testing.

[0003] In order to overcome these challenges, the present invention proposes an innovative batch testing method for multi-type and multi-board frame-type devices, aiming to simplify the testing process, improve production efficiency, reduce costs, and enhance the accuracy and reliability of testing.

[0004] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0005] In view of the problems existing in the prior art, an object of the present invention is to provide a method for batch production testing of frame-type equipment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A method for batch production testing of frame-type equipment, the method comprising the following steps: S1. Install the BKP backplane into the frame, and then install each board to be tested on the BKP backplane to form a complete frame. The number and type of boards are identified by the backplane self-identification circuit and stored in the database. Then, the PC UI server test software is opened to start equipment production testing. S2. Upgrade the software of each board: The PC UI server sends the software upgrade packages of the MGMT management unit and the HANDLE processing unit respectively through the network port connected to the SWITCH switching unit; the MGMT management unit and the HANDLE processing unit identify the received software package; after identifying the correct software package header, the MGMT management unit and the HANDLE processing unit perform CRC check on the software package to ensure the correctness of the received data; then, the MGMT management unit and the HANDLE processing unit will use the software package to upgrade their own CPU program to ensure that the shipped software is the latest version; after the upgrade is completed, the MGMT management unit and the HANDLE processing unit return the upgrade completion status to the PC UI server through the Ethernet port through the switching unit, and the PC UI server records the upgrade status and displays it on the UI interface; S3, perform power supply unit function test: including fan start, stop, wind speed adjustment, power module temperature, current, and voltage test; PC UI server first sends test instructions to MGMT management unit through exchange, and MGMT management unit sends test commands to power supply unit through IIC digital interface connected to power supply unit. After receiving the test command, power supply unit first performs fan wind speed adjustment test, first adjusts wind speed to 100%, returns to PC UI server through IIC interface to display wind speed 100%; then adjusts wind speed to 50%, and returns to PC UI server through IIC to display 50%; similarly, power supply unit then performs fan start, stop, temperature, current, and voltage test according to the instructions and returns the status to PC UI server; after a series of tests, PC UI server determines whether the power supply unit function is complete according to the test results sent back by the power module, and finally displays and records the test results on UI interface; S4. Perform functional test on MGMT management unit and HANDLE processing unit: Since MGMT management unit and HANDLE processing unit share hardware, only test description is given to MGMT management card; management card unit tests board temperature, hard disk information, IP, RTC clock, SN number, and MAC number; first, PC UI server sends test command to management card through network port, and management card starts testing after receiving the command; management card obtains management card temperature by reading its own temperature sensor, reads mounted hard disk information through USB port, verifies whether management card IP is written by ping packet, obtains local time by reading internal time of its own RTC clock chip, and sends real-time time to management card at the same time; detects whether software information and version are complete by SN and MAC of PC UI server; finally, uploads detected information to PC UI server for display and storage.

[0007] Furthermore, the specific method for the backplane self-identification circuit in step S1 to identify the number and type of boards is as follows: When any type of board is inserted into a slot, the board identification module will first detect the insertion of the board through the detection circuit, and then collect the analog quantity of the board type through the high-precision SAR-ADC. Different boards have different analog quantities. After receiving the data, the acquisition MCU analyzes and judges it, and then notifies the PC UI interface through the serial port what board is inserted in the current slot and how many boards are inserted in the entire BKP backplane.

[0008] By adopting the above technical solution, the present invention has the following beneficial effects: 1. Save one production test link for single board cards, greatly improving test efficiency; 2. The introduction of intelligent production testing process greatly reduces manual intervention in production testing and improves the fault tolerance of testing; 3. Reduce a large number of different types of test tools and production processes, thereby saving production costs in disguise; 4. No manual intervention is required, the operation is simple, and the mass production test results are automatically collected and saved in a table format to facilitate problem tracing; 5. Use one set of hardware to realize production testing of all boards and cards, with good compatibility and scientific expandability, and can be applied to various types of equipment.

DETAILED DESCRIPTION

[0011] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0013] The present invention aims to overcome a series of challenges faced by current frame-type equipment when performing batch production testing of multiple types of boards, including: Complexity and inefficiency of the testing process: When performing production testing on multiple types of boards, the existing program burning, hardware testing, and software testing processes are not only cumbersome but also inefficient.

[0014] High cost problem: Traditional testing processes require a large number of special test tools, which are expensive. At the same time, the equipment investment and labor costs of the test line also account for a considerable proportion.

[0015] Compatibility limitations of test tools: Current test tools can usually only test a single type of board and lack flexibility and versatility.

[0016] Insufficient intelligence level: In the large-scale production testing process, there is a lack of intelligent testing methods, resulting in inaccurate testing process and difficulty in improving efficiency.

[0017] In response to the above problems, the present invention provides a batch production testing method for multiple types of boards of frame-type equipment, in order to simplify the testing process, effectively reduce costs, enhance the compatibility of testing tooling, and make the testing process intelligent, thereby significantly improving the efficiency and quality of production testing.

[0018] The present invention innovatively proposes an integrated production test process. First, the BKP backplane is installed inside the frame, and then each board to be tested is installed on the BKP backplane to form a complete frame. The number and type of boards are identified by the backplane self-identification circuit and stored in the database, and then the PC UI server test software is opened to start equipment production testing.

[0019] First, the software of each board is upgraded. The PC UI server sends the software upgrade packages of the MGMT management unit and the HANDLE processing unit through the network port connected to the SWITCH switching unit. The MGMT management unit and the HANDLE processing unit identify the received software package. After identifying the correct software package header, the management unit and the processing unit will perform CRC check on the software package to ensure the correctness of the received data. After that, the management unit and the processing unit will use the software package to upgrade their own CPU program to ensure that the shipped software is the latest version. After the upgrade is completed, the management unit and the processing unit return the upgrade completion status to the PC UI server through the Ethernet port through the switching unit. The PC UI server records the upgrade status and displays it on the UI interface.

[0020] Perform a functional test on the power supply unit, including fan start, stop, wind speed adjustment, power module temperature, current, and voltage test. The PC UI server first sends a test command to the management unit through exchange. The management unit sends the test command to the power supply unit through the IIC digital interface connected to the power supply unit. After receiving the test command, the power supply unit first performs a fan wind speed adjustment test, first adjusts the wind speed to 100%, and returns to the PC UI server through the IIC interface to display the wind speed of 100%; then adjusts the wind speed to 50%, and then returns to the PC UI server through the IIC to display 50%; similarly, the power supply unit performs fan start, stop, temperature, current, and voltage tests according to the instructions and returns the status to the PC UI server. After a series of tests, the PC UI server will determine whether the power supply unit function is complete based on the test results sent back by the power module, and finally display and record the test results on the UI interface.

[0021] Perform functional tests on the MGMT management unit and the HANDLE processing unit. Since the MGMT management unit and the HANDLE processing unit share hardware, only the MGMT management card is tested. The management card unit mainly tests the board temperature, hard disk information, IP, RTC clock, SN number, and MAC number. First, the PC UI server sends a test command to the management card through the network port, and the management card starts the test after receiving the command; the management card obtains the management card temperature by reading its own temperature sensor, reads the mounted hard disk information through the USB port, verifies whether the management card IP is written by means of a ping packet, obtains the local time by reading the internal time of its own RTC clock chip, and sends the real-time time to the management card at the same time, and checks whether the software information and version are complete by checking the SN and MAC of the PC UI server. Finally, upload the detected information to the PC UI server for display and storage.

[0022] Through a redesigned production test process for frame-type equipment, the single-board test and the whole frame test process are combined into one process, that is, all the production test processes of the above traditional solutions can be completed by only performing production test on the frame. During the whole process, the human only needs to turn on the computer and connect the computer and the frame-type equipment harness to start unmanned operation. All production test results are stored in the database, and when there is a device that fails the production test, a corresponding alarm prompt will be issued.

[0023] The production test method involved in the present invention has good scalability. A multifunctional BKP backplane is redesigned to be compatible with all boards and cards. The same slot can automatically identify the type of inserted board and card to determine which board to use for production test process. It is backward compatible with other products and has strong scalability. When a new product needs to be tested, it only needs to be configured and set on the host computer interface to correspond to the corresponding product. At the same time, multiple devices can be tested through USB expansion, which greatly improves the efficiency of production test.

[0024] The present invention saves the original numerous test tools and manual intervention links of traditional production testing by optimizing the test process, completely entrusts the test to the computer, streamlines the test steps, reduces the production test cost, improves the efficiency of mass production testing, and can automatically record the test results to facilitate later quality traceability.

[0025] How to connect the frame device to the computer Figure 1 As shown in the figure, the frame device is connected to the computer through the SWITCH switch card network port, and the tested devices are centrally managed through the network port. It can support up to 32 devices to be tested at the same time, which greatly improves the mass production efficiency. This method saves the time of the original process of burning and testing each board separately and then testing the whole frame.

[0026] like Figure 2 The figure shows the principle block diagram of the BKP backplane card identification module. When any type of card is inserted into a slot, the card identification module will first detect the insertion of the card through the detection circuit, and then collect the analog quantity of the card type through the high-precision SAR-ADC. Different cards correspond to different analog quantities. After receiving the data, the acquisition MCU analyzes and judges, and then notifies the PC UI interface through the serial port what card is inserted in the current card slot and how many cards are inserted in the entire BKP backplane.

[0027] like Figure 3As shown in the figure, it is the interface of the general mass production test software. When performing mass production test of frame-type equipment, first open the interface of the general mass production test software and select the model of the device under test. In this option bar, you can select all relevant models. When there is a new model, you can update the device model by loading the configuration file. This method can achieve the goal of expanding the production test of additional devices with the same production test software; secondly, set the number of devices under test. The production test software can support up to 32 devices to be tested at the same time. It can greatly improve the efficiency of mass production; next, set the relevant parameters of the serial port, including the current serial port number and the baud rate of the current serial port. Of course, when the device is connected, the software can also automatically monitor and identify the current serial port number. Next, set the SN number of the device under test, and use the SN number to distinguish each device and trace subsequent problems. Finally, click the "Open Serial Port", "Connect Device" and "Start Test" buttons in sequence, and the general test software will start to automatically test the device under test. During the test, when a certain sub-card is tested, the test information printing window of the interface of the general mass production test software begins to output the current board information under test (including various test information printing); when the test information printing window prompts that the whole machine test is completed, the system automatically issues a relevant prompt tone to prompt the relevant staff to replace the next batch of equipment. After the mass production test is completed, the user can click the "Save Data" button to save the configuration information, so as to repeat the upper computer software configuration work when producing the same type of product next time. You can also click the "Export Data" button to export the test data; like Figure 4 The table shown in the figure shows the test results automatically recorded by the software. The table clearly records the "model", "SN number", "test time", "test results" and "problem record" information of each device. The reason for failing the test can be marked for each device that failed the test. This will facilitate the maintenance workers to repair and maintain the problematic equipment in the future.

[0028] like Figure 5 As shown in the figure, it is a mass production test flow chart. This flow chart describes the entire mass production test process in detail. First, make a skilled connection and power on the device, then open the host computer interface and click the relevant operation button, the system will automatically run the test case and perform mass production test on the device under test. At the beginning of the test, the program will be burned on the board under test. After the burning is completed, the port test (including the front panel port and the back panel port) and LED indicator test of the frame device will be carried out (the corresponding interfaces of different devices are not completely consistent, so they are simply listed here). When a problem is encountered during the test, the fault information at this time is recorded and the next board test is continued. Until the entire frame test is completed. After that, the system will automatically save the test data to the computer desktop and send a prompt sound to the operator.

[0029] After the above set of standardized mass production test processes, the test of the entire frame is completed. The present invention proposes a mass production test method and system for frame-type equipment that integrates parts into a whole, which innovatively solves the shortcomings of traditional frame-type equipment; mass production test, such as low efficiency and high cost.

[0030] Finally, it should be noted that 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
