Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to an automated testing device for monitors based on ESP32. Background Technology

[0002] With the widespread application of intelligent monitors in security, industry, and home applications, their functions are becoming increasingly complex, encompassing multiple system modules such as image acquisition, audio input / output, wireless communication, environmental sensing, and digital interfaces. To ensure product quality, complete unit testing has become a crucial step in the production process. Currently, complete unit testing of monitors mostly employs manual testing or semi-automatic testing fixtures based on single-function circuits. During manual testing, operators must connect each device individually, manually trigger function points, observe responses, and record test results. Traditional testing fixtures often only support specific functional modules, such as power supply testing or network connectivity testing, failing to cover all functions of the entire unit. Furthermore, in mass production, the large number of products under test, the numerous test indicators, and the high intensity of manual operation easily affect test consistency and stability, thus impacting overall quality management. Simultaneously, traditional fixtures lack network functionality, preventing automatic uploading and tracking of test data, which fails to meet the current requirements of traceability, automation, and digitalization in intelligent industrial manufacturing.

[0003] The existing technology has at least the following problems in its use:

[0004] If multiple items need to be tested, multiple fixtures are required to work together, which increases the complexity of wiring and the burden on testers. Utility Model Content

[0005] This invention provides an automated testing device for monitors based on ESP32, which solves the technical problem that existing technologies require multiple fixtures to be used in conjunction to test multiple items, increasing wiring complexity and the burden on testing personnel.

[0010] Furthermore, it also includes: multiple cover plates, which are rotatably mounted on the frame and correspond one-to-one with the test chambers; and a position sensor, wherein a detection groove is provided on the side wall of the test chamber near the rotating shaft of the cover plate, and the position sensor is installed in the detection groove.

[0011] Furthermore, it also includes a power supply unit, installed inside the control compartment.

[0012] This utility model provides an automated detection device for monitors based on ESP32, with the following advantages:

[0026] Example:

[0027] like Figures 1 to 5 As shown, this embodiment provides an automated testing device for a monitor based on ESP32, including: a rack 11 with a control chamber 12 and multiple test chambers 13, wherein the test chambers 13 are located within the control chamber 12; a control unit is located within the control chamber 12; and multiple test units are installed within the test chambers 13, and the multiple test units are electrically connected to each other, and the test units are communicatively connected to the control unit.

[0028] In this embodiment, the rack 11 is constructed from engineering plastic. Its control compartment 12 corresponds to the power input and signal interface division in the instruction manual. It internally reserves mounting positions for the power supply unit 16 and an RS485 to USB communication module, enabling centralized management of power supply and communication. The test compartments 13 are independent test slots, with a total of six. Each test compartment 13 has a limiting guide groove and support platform on its inner wall that fits the test board body 21, ensuring accurate positioning of the test board body 21 during installation and preventing connection failure between the detection interface 22 and the monitor under test due to misalignment. It also isolates signal interference from adjacent test compartments 13, ensuring the independence of testing in each slot. The control unit, based on the ESP32 module, integrates a dual-core processor, abundant GPIO, ADC, and WIFI communication resources. On one hand, it establishes communication with multiple test units via the RS485 bus to issue test commands and receive test data. On the other hand, it can upload test results to the cloud platform via WIFI, fulfilling the needs of cloud data upload and remote traceability. Simultaneously, the control unit also communicates with the host computer test software via RS485. It supports USB module connection, enabling centralized command management and data parsing.

[0029] Furthermore, the test unit includes: a test board body 21, with an installation slot provided in the test chamber 13, and the test board body 21 installed in the installation slot; a detection interface 22, which is communicatively connected to the test board body 21; a first test button 23, which is installed on the test board body 21 and located on one side of the detection interface 22; a first test indicator light A24, which is located around the first test button 23; and a first test indicator light B25, which is located around the first test button 23.

[0030] In this embodiment, the test board body 21 is an independent test board body 21, which is precisely fixed by cooperating with the limiting guide groove and support platform of the test chamber 13 through the mounting slot. The onboard power management module receives the DC 5V voltage from the power supply unit 16 and supplies power to the components on the board through the LDO voltage regulator circuit, and integrates overvoltage, undervoltage and overcurrent protection circuits. The detection interface 22 is a TYPE-C interface. The test interface module integrates ESD electrostatic protection, overvoltage protection and level conversion circuit, which can realize the power supply of the monitor under test, serial communication and test command interaction. The first test button 23 is a green button, which realizes confirmation of success and plays audio. It can only be operated when the cover 14 is open, and is used for manual confirmation of the test result or to trigger the audio test function. The first test indicator A is a green indicator light. When the test unit completes all functional tests and determines that it is qualified, it is controlled by the control unit to light up. The first test indicator B is a white indicator light. After the test process starts, the indicator light flashes continuously until the test ends and the state changes, so that the operator can intuitively judge the test progress.

[0031] Furthermore, the test unit also includes: a second test button 26, mounted on the test board body 21, located on the other side of the detection interface 22; a second test indicator light A27, located around the second test button 26; and a second test indicator light B28, located around the second test button 26.

[0032] In this embodiment, the second test button 26 is a red button, used to confirm failure and exit the process. It is located on both sides of the detection interface 22, separate from the first test button 23, to avoid operational confusion. When an abnormality occurs during the test, such as no response from the monitor or abnormal data, the operator can press this button to confirm the test failure or trigger a forced exit of the test process. The second test indicator light A is a red indicator light. When the control unit detects a functional abnormality in the monitor through the functional test circuit module, such as an abnormal NTC signal or no response from the lens, it controls this indicator light to illuminate, indicating that the test is unqualified. The second test indicator light B is a green indicator light. When the test unit is powered on and the power management module is working normally, this indicator light is constantly on, used to provide feedback on the power supply status of the test unit and avoid test misjudgment due to power supply problems.

[0033] Furthermore, it also includes: multiple cover plates 14, which are rotatably mounted on the frame 11 and correspond one-to-one with the test chamber 13; a position sensor, wherein a detection groove 15 is provided on the side wall of the test chamber 13 near the rotating shaft of the cover plate 14, and the position sensor is installed in the detection groove 15.

[0034] In this embodiment, the cover plate 14 is made of transparent acrylic material. The rotating connection structure allows for convenient opening and closing. When closed, it can isolate external environmental interference, preventing the PIR function test of the monitor under test from being affected. It also serves as a dustproof function, extending the service life of the test unit. The position sensor is a Hall sensor. A magnet is provided on the cover plate 14. When the cover plate 14 is closed, the magnet approaches the Hall sensor, and then the Hall outputs a low level. After the test board body 21 recognizes this signal, it enters the "occlusion detection" mode. In this state, if no human activity is detected, the PIR should always output a low level. If a high level appears, it is judged as unqualified.

[0035] When the magnet moves away from the Hall sensor, the Hall signal disappears, and the PIR enters the "normal detection" mode. At this time, when someone performs a button operation, the PIR sensor should detect the human movement and output a high level. The sensitivity and function of the PIR sensor are judged by judging the detected state when the cover 14 is opened and closed.

[0036] Furthermore, it also includes a power supply unit 16, which is installed inside the control compartment 12.

[0037] In this embodiment, the power supply unit 16 is an AC-DC power module. Its input terminal is connected to external AC 220V AC power, and its output terminal is converted to DC 5V DC power. It supplies power to the control unit, all test units, and RS485 to USB module through centralized wiring. The power supply unit 16 integrates multi-stage voltage regulation circuits and overvoltage, undervoltage, and overcurrent protection circuits to prevent external voltage fluctuations from damaging the test modules. At the same time, it ensures that the power supply voltage of each test unit is stable and consistent, avoiding deviations in test results due to power supply differences. In addition, the power supply unit 16 is also equipped with a power indicator light, which is located outside the control compartment 12. When the external power supply is normal and the module is working stably, the indicator light is always on, which makes it easy for operators to quickly troubleshoot power supply faults.

[0038] In summary, this utility model adopts an integrated structural fixture, the main body of which is divided into two functional areas: a power input and signal interface area and a test slot area. The physical structure is compact and reasonable, possessing good maintainability and expandability. The test slot area uses six isolated independent test slots, each equipped with a limiting guide groove, an interface alignment structure, and an acrylic transparent cover plate 14. This effectively avoids insertion and removal errors of the monitor during testing and interference from the external environment on the PIR function test, thereby improving the accuracy and stability of the testing process. Simultaneously, the closed state of the cover plate 14 serves as one of the test trigger conditions, effectively preventing misoperation.

[0039] In terms of power supply safety, the entire unit adopts a centralized AC-DC power module, which converts the external AC 220V into a unified DC 5V output for use by the main test board 21 and the communication module. The power output terminal integrates multi-stage voltage regulation and protection circuits, which have overvoltage, undervoltage and overcurrent protection capabilities, fundamentally ensuring the power supply stability and electrical safety of the tooling, and improving the overall reliability of the equipment;

[0040] In terms of communication management, this fixture uses an RS485 to USB communication module to achieve bus communication between multiple test boards (21 main units) and connect them to a host computer. The module is driverless and plug-and-play, supporting multi-board cascading and command broadcasting, effectively improving data transmission efficiency and simplifying system wiring complexity. Simultaneously, the ESP32 main controller integrates WIFI functionality, allowing test data to be automatically uploaded to a cloud platform, achieving closed-loop data management and remote traceability, meeting the requirements of intelligent manufacturing and quality control.

[0041] In terms of core test control, each test slot corresponds to an independent test board 21, using an ESP32 as the main controller and integrating functional modules such as serial communication, ADC, GPIO, current detection, SPI communication, and WIFI. It supports automated testing and judgment of key components such as NTC, PIR, LED, voltage, current, buttons, lenses, and FLASH. The test board 21 is highly integrated, covering all functional points of the product under test, and has high adaptability and scalability, supporting switching between multiple product categories.

[0042] In terms of human-computer interaction, the main body 21 of the test board is equipped with multiple status LEDs and manual buttons, allowing for manual confirmation of test results when the cover 14 is open. The status LEDs distinguish between power, testing in progress, success, and failure, while the buttons are configured to confirm pass and fail handling functions. The interface is user-friendly and intuitive, suitable for operators of varying experience levels, thus lowering the operational threshold. The linkage control with the host computer testing software and the graphical interface significantly enhance the intelligence and operability of the entire tooling system. Through the host computer testing software, users can achieve unified visual management of the test status of multiple slots via a graphical interface on a PC, eliminating the need for manual confirmation of the test status of each slot and avoiding misjudgments and missed tests. Simultaneously, the system supports centralized feedback and categorized display of batch test results from multiple slots (through color coding, status icons, and text prompts), improving interaction efficiency and information readability. The host computer also features one-click start of the test process, real-time process monitoring, test result recording and uploading, and fault alarm functions, which greatly optimizes the operating experience and management efficiency of testers. It also provides strong support for quality closed-loop control and test traceability through data retention and remote uploading functions.

[0043] In terms of automation and information technology, the main program of the test board has built-in automatic identification, test judgment, data acquisition and uploading logic. All test items can be executed centrally through commands and the results can be automatically judged, completely avoiding subjective judgment errors in the traditional manual testing process and realizing the automation, standardization and batch processing of the testing process. At the same time, the test results are uploaded to the database, which can support subsequent analysis, traceability and statistical analysis, and improve the overall quality management level.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
