Description

Technical Field

[0001] This invention relates to the field of integrated testing fixtures, specifically a one-to-thirty-two wireless product integrated testing device. The integrated testing device, also known as an automatic test equipment (ATE), is based on replacing manual labor with an automated system to achieve efficient and accurate product testing. It is widely used in manufacturing and electronic information fields where quality and efficiency must be guaranteed.

[0002] Its main application areas include: 1. Electronics manufacturing: testing PCBs (printed circuit boards), consumer electronics (mobile phones, computers), automotive electronics, etc., to troubleshoot problems such as short circuits, poor soldering, and component failures; 2. Industrial manufacturing: performing performance and reliability tests on industrial components such as sensors, connectors, and relays, as well as equipment such as motors and valves; 3. Semiconductor industry: used for chip design verification, wafer testing, and final testing to check whether the electrical performance and functions of chips meet the standards; 4. New energy industry: testing key parameters such as capacity, charge and discharge efficiency, and insulation of lithium batteries and photovoltaic modules to ensure product safety and performance.

[0003] This invention focuses on the fields of electronic manufacturing and industrial manufacturing, and can be applied to automated testing scenarios for computer software, embedded systems, electronic devices, etc. Background Technology

[0004] For Bluetooth products, much testing currently relies on test boxes, many of which only have a 1-to-2 setup. This leads to excessively long testing times and low production efficiency. Bluetooth chips typically run operating systems, and the time required for Bluetooth startup, broadcasting, searching, and connection varies. This consistently results in low testing efficiency for many products. This is due to the limited capacity of the Bluetooth test box and the testing speed of the Bluetooth devices themselves. Because the blue test box is a separate unit, the Bluetooth testing process is independent, which is time-consuming. Furthermore, the products' functions are not singular, and the process... The addition of steps complicates the product testing process, and independent processes are prone to missed or incorrect inspections. For testing semi-finished products, the efficiency of workers is low when placing one or a few boards. Taking the gaming chair controller solution as an example, it includes not only Bluetooth, but also RF433 remote control, microphone pickup, and LED strip driver. Testing these products one by one in each process distributes the process across the production line, leading to a series of problems, low labor efficiency, increased processing costs, and poor product delivery timeliness. In addition, the step-by-step testing process is not only inefficient but also requires a large amount of manpower, which drives up the product testing cost.

[0005] Regarding the issues raised in the product manufacturing and testing: 1. This invention treats the product as a black box for testing, without needing to know the cause of the product's defects. The key is to test out the defects and screen out defective products, thus improving testing efficiency. 2. To save time during Bluetooth startup of the LED strip, other parameters of the product can be tested separately during the waiting time: such as the receiving sensitivity of RF433; the microphone pickup sensitivity; the driving of the LED strip, etc., and the step-by-step process test can be transformed into a comprehensive test. 3. To improve the timeliness of testing, synchronous testing is adopted for the products. The products are tested as a whole board, and if there are a total of 32 panels, they will be tested as 32 panels (4 columns * 8 rows). 4. After the test pressure is detected, the detection switch will automatically start the test after detecting the pressure action, which can be operated wirelessly via buttons; 5. The test rack has grooved sides to facilitate panel separation. Panels can be separated during the testing of LED strip products, improving work efficiency. 6. To facilitate differentiation, the yield indicator light is divided into 4 display boards, which makes it easy to correspond one-to-one with the tested boards and quickly identify defective boards.

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an adaptive, high-coverage, cross-platform automated testing solution with intelligent fault location capabilities. This solution aims to reduce test script maintenance costs, improve test coverage and fault location efficiency, and adapt to the needs of rapid iterative development.

[0019] This invention provides a comprehensive testing device for one-to-thirty-two wireless products, which includes a main control board unit, a USB expansion unit, a group detection board unit, a computer connection unit, and a comparison unit.

[0020] The first is the main control board unit: The main control board unit includes a power supply module, a Bluetooth signal transmission / reception module, a 433.92MHz signal transmission module, a color information control command module, and a sound detection signal module; when the test stand is pressed down, it actively enters the automatic test function and emits sound to detect the microphone detection signal.

[0021] Secondly, there is the USB expansion unit: the USB expansion unit is divided into two-level expansion or one-level expansion; the one-level expansion uses a one-to-thirty-two hub (USB Hub); the two-level expansion uses USB expansion, that is, through a USB hub (USB Hub) or docking station, to expand a single USB interface into multiple.

[0022] The third is the group testing board unit: the group testing board unit can test the product under test simultaneously after passing through the USB expansion unit, and can automatically compare all output signals to ensure consistency without needing to be connected to a computer.

[0023] Fourthly, there is the computer connection unit: the computer connection unit loads the control signals and feedback signals required by the group detection board unit through the main control board unit, and can go offline after loading; the loading process can be stored in the main control board unit, and the main control board unit can work offline after loading.

[0024] The fifth is the comparison unit. When the main control board unit is expanded to 32 channels via the USB expansion unit and simultaneously controls the 32-channel group detection board unit to test the product, the comparison unit will check synchronously during the test and will display an indicator light if an abnormality is found.

[0025] The preferred solution is a main control board unit, and the operation steps are as follows: S1 Test fixture pressure unit: Once the test fixture is successfully pressured, the test fixture actively uses RF433 and Bluetooth commands to put the controller under test into test mode and detect the corresponding parameters; the detected parameters and status information are transmitted through the UART between the board under test and the group detection. S2 Control: When the RF433 command is responded to, it is directly transmitted via UART communication of the board under test. If the Bluetooth signal is successfully detected, the main control's transmit / receive Bluetooth signal module transmits the Bluetooth transmit / receive detection pass to the U4 MCU. The U4 transmits the blue detection success information to the group detection board through the USB expansion unit. Finally, the MCU of the group detection board integrates the collected information to determine the pass rate of the tested product: if the light is on, it is a good product; if the light is off, it is a defective product. S3 Power Supply: Power supply to the target board, with power management via U4; S4 Signal Control: Transmits 433MHz commands at low power to simulate long-distance communication. If the board under test can still receive the signal, the wireless receiving part of the board under test is good. S5 Comparison and Testing: The board under test enters the test mode, and the Bluetooth IC continuously detects the Bluetooth signal of a specific group. The group information corresponds one-to-one with the board information. S6 Test Result Judgment and Display: After entering the test mode, the audio sound unit emits a sound every 2 seconds. In the test mode, the test board detects the audio signal in real time. If the audio signal detected in the test mode reaches the threshold, the quality of the product is determined. During the test, the comparison unit will check synchronously and display an indicator light if an abnormality is found.

[0026] The preferred solution is a grouped detection board unit, with the following operation steps: T1 receives Bluetooth information: Group detection board U2 receives Bluetooth good information; T2 Bluetooth Information Judgment: The MCU uses the information received via UART to comprehensively determine the yield rate of the board under test. T3 Result Judgment: The 8 LED indicator lights correspond one-to-one with the tested panel; The T4 judgment result shows that the real-time monitoring audio signal of the tested board has reached the threshold through the test mode, and the quality of the product is determined; the comparison unit (5) will check synchronously during the test, and an indicator light will be displayed if an abnormality is encountered.

[0027] The preferred solution is that when the main control board unit receives the pressure signal from the test fixture, the comparison unit checks synchronously, and an indicator light will be displayed if an abnormality is found; if no abnormality is found, the next batch of products will continue to be burned.

[0028] The preferred embodiment is that the main control board unit can memorize the last loaded programming code and can update the programming code using the computer connection unit; the computer connection unit can store multiple sets of programming codes and update them as needed.

[0029] The preferred embodiment is that the comprehensive testing device for wireless products includes a main control board unit, a USB expansion unit, a group detection board unit, a computer connection unit, and a comparison unit. The main control board unit, the USB expansion unit, the computer connection unit, and the comparison unit can remain fixed. By simply replacing the group detection board unit, different products under test can be tested, including products under test with wireless functions and products under test with communication functions.

[0030] The preferred solution is that the USB expansion unit is divided into two-level expansion or one-level expansion; the one-level expansion uses a 32-port USB hub; the two-level expansion uses USB expansion, that is, through a USB hub or docking station, to expand a single USB interface into multiple ports; commonly used are 4-port and 8-port, either 4-port first and then 8-port or 8-port first and then 4-port; to ensure the burning quality, it is a power-powered model: an external power supply is required.

[0031] The preferred approach involves using a color information control module that controls the color of devices or software by specifying a target and defining color parameters. This is commonly seen in programming, device control, and design software. For example, a common format would be: Hardware device control (such as LEDs, screens); Format: Control [Device ID], [Color Control Function], [Color Parameters]; Example: Control LED1 to light up RGB(255,0,0) (Light up LED1, the color is pure red, and the RGB values ​​correspond to the brightness of the red, green and blue channels respectively).

[0032] The preferred embodiment is a sound detection signal module (15), which is an electronic module used to detect sound signals and convert them into electrical signals. It is widely used in various occasions where sound detection is required. The working principle is as follows: the sound detection signal module usually contains a sound-sensitive element, such as an electret condenser microphone. When a sound wave reaches the microphone, it causes the electret diaphragm inside the microphone to vibrate, resulting in a change in capacitance, which in turn generates a corresponding small voltage change. This voltage change is then amplified and processed, and converted into an electrical signal that can be recognized by other devices. Its common types and characteristics include: X1 LM386-based sound sensor module: It adopts the LM386 audio processing chip, which has the characteristics of low power consumption, adjustable gain, wide power supply voltage range, few external components and low total harmonic distortion. It can amplify audio signals, detect the presence or absence of ambient sound or determine the intensity of sound. The X2 LM393-based sound detection sensor module uses an LM393 comparator as a voltage comparator, comparing the signal with a preset threshold voltage to output a digital signal. The module also includes a potentiometer to adjust the sound detection threshold. X3 direct-reading noise decibel detection module: such as the AS11-x series from Alsen Technology, which is manufactured using a multi-point calibration process, has high detection accuracy and high sensitivity, features a unique stainless steel probe independent packaging design, and reserves multiple output interfaces, making it suitable for various application integrations. Its output methods include: Y1 Analog Output: Usually represented by AO, it outputs the microphone's voltage signal in real time, with a voltage range of 0-5V, which can reflect continuous changes in sound intensity; Y2 Digital Output: Generally represented by DO, it outputs high and low level signals when the sound intensity reaches a certain preset threshold, used for simple sound presence or absence detection.

[0033] The preferred solution is a Bluetooth signal transmitting / receiving module (12); a Bluetooth module refers to a basic circuit set of chips that integrate Bluetooth functionality, used for short-range 2.4G wireless communication; the working principle is that when a Bluetooth module communicates, one must be the master and the other the slave. The master device initiates a call, first searching for nearby discoverable Bluetooth devices, and then pairing with the slave device. After pairing, the master can initiate a call to the slave device. After successful connection establishment, both parties can send and receive data; the following is a detailed introduction to the Bluetooth module: Classification: By application and supported protocols, Bluetooth modules can be divided into Classic Bluetooth (BT) modules and Bluetooth Low Energy (BLE) modules. Classic Bluetooth modules are generally used for large data transmissions, such as voice and music; the biggest advantage of Bluetooth Low Energy modules is their reduced cost and power consumption, making them suitable for products with high real-time requirements, such as smart home devices and data transmission from sensor devices.

[0034] Based on protocol support, Bluetooth modules can be categorized into single-mode and dual-mode modules. A single-mode Bluetooth module supports only one Bluetooth protocol, while a dual-mode Bluetooth module supports both Bluetooth Classic and Bluetooth Low Energy protocols.

[0035] Based on application, there are Bluetooth data modules and Bluetooth audio modules, etc. Bluetooth data modules generally use BLE Low Energy Bluetooth modules, which have extremely low operating and standby power consumption; Bluetooth audio modules, because audio requires high bitrate data transmission, are more suitable for using BT Classic Bluetooth modules.

[0036] The preferred option is to use a module that transmits a 433.92MHz signal. The 433.92MHz (megahertz) frequency band is an unlicensed radio frequency band widely used for short-range wireless communication in civilian and industrial applications. It is primarily used for low-rate, low-power wireless data transmission.

[0037] The core application scenarios are as follows: Smart home control: Commonly found in remote control switches, smart door locks, curtain motors, and light remote controls, this frequency band enables the transmission of commands between devices (such as switching on / off and adjusting modes). Industrial / Agricultural Monitoring: Sensors (temperature and humidity, soil moisture, smoke sensors, etc.) transmit data to the receiving end without wiring, making them suitable for outdoor or complex environments; Wireless remote control devices: garage door remotes, electric door remotes, toy remote control cars, etc., which utilize their short-range (usually tens to hundreds of meters) transmission characteristics to achieve control; Security alarm system: Signal transmission between door and window magnetic sensors, human infrared detectors and alarm host, and the sending of wireless signals when an alarm is triggered.

[0038] The frequency band is characterized by its unlicensed use: no frequency band license needs to be applied for from the radio management department, reducing usage costs and making it suitable for civilian and small equipment.

[0039] Its transmission characteristics include better penetration (wall-penetrating ability) than high-frequency bands (such as 2.4GHz), but lower transmission rate (usually at the kbps level). It is more suitable for transmitting instructions and small-volume data, but not suitable for high-definition video and large file transmission.

[0040] Because it belongs to an open frequency band, it may interfere with other devices on the same frequency band (such as other remote controls or wireless doorbells), resulting in unstable signals.

[0041] Related hardware modules: The core of its application is the wireless module (transmit / receive module) based on the 433.92MHz frequency band. Common ones include super regenerative modules: low cost, low power consumption, suitable for short distance (within about 50 meters) and scenarios where stability requirements are not high (such as toy remote control).

[0042] The preferred option is to replace the 433.92MHz band with unlicensed communication bands, such as the 2.4GHz band, the Sub-1GHz band, and the 5GHz band. Unlicensed communication bands refer to bands that can be shared by an unlimited number of independent users without requiring a frequency license from a regulatory authority. The following are some common unlicensed communication bands: The 2.4GHz band, with a frequency range of 2400-2483.5MHz, is a globally unlicensed band. Its characteristics include high data rates (Wi-Fi up to 600Mbps, Bluetooth up to 2Mbps), and a typical transmission distance of 10-100 meters. However, it is significantly affected by wall attenuation, and the large number of devices using this band leads to considerable interference. It is primarily used in smart homes and consumer electronics, such as wireless routers, Bluetooth headsets, and smart bracelets.

[0043] Sub-1GHz band: The frequency range is between 300MHz and 1GHz, with specific frequency bands varying by country. This band offers ultra-long-distance transmission capabilities, reaching several kilometers in open environments, with strong penetration and diffraction ability, making it suitable for scenarios involving walls and underground transmission. However, the data rate is relatively low, typically less than 100kbps. Common applications include LoRa technology, which uses the 433MHz band in China and the 868MHz band in the European Union for remote IoT applications such as agricultural sensors and remote meters; technologies like Sigfox and Z-Wave also use this band.

[0044] 5GHz band: Some 5GHz bands are unlicensed, such as 5150-5850MHz. This band features high speed and low interference, but has a small coverage area. It is mainly used in areas such as high-definition video transmission and enterprise Wi-Fi. The US FCC is also considering opening up the 5350-5470MHz and 5850-5925MHz bands as unlicensed bands.

[0045] Compared with existing technologies, the beneficial effects of this invention are: 1. Reduced testing difficulty for workers; 2. Simplified production testing process, reducing manual labor and product inspection time; 3. Synchronous testing saves a significant amount of working time. The average testing time for a single Bluetooth board is about 15 seconds, while synchronous testing can test 32 target boards simultaneously, reducing the average testing time for each board to approximately 0.5 seconds; the more complex the product, the greater the time saved; 4. During comprehensive testing, the Bluetooth startup time of the product is converted into effective testing time; 5. With slotted test racks, workers can begin distributing and packaging boards while waiting for the entire board to complete testing, saving on board separation workstations; 6. Due to process optimization and product timing, certain processing costs are saved; 7. Significantly reduced costs, decreasing the original testing fee from 0.15 yuan to 0.03 yuan; the more complex the product, the greater the savings. Attached Figure Description

Detailed Implementation

[0048] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The realization of the purpose, functional characteristics, and advantages of the invention will be discussed in conjunction with the embodiments and with reference to the appendix. Figure 1 To be continued Figure 18Further explanation is provided below. The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] In one embodiment of the present invention, this example serves as a comprehensive testing device 100 for one-to-thirty-two wireless products, as shown in the attached diagram. Figure 1 and appendix Figure 2 It includes a main control board unit 1, a USB expansion unit 2, a group detection board unit 3, a computer connection unit 4, and a comparison unit 5; wherein the computer connection unit 4 is connected to a computer 80, and the group detection board unit 3 and the comparison unit 5 are connected to the products under test 6, which consists of 32 products.

[0050] The first is the main control board unit 1: refer to the attached document. Figure 3 The main control board unit 1 includes a power supply module 11, a Bluetooth signal transmission / reception module 12, a 433.92MHz signal transmission module 13, a color information control instruction module 14, and a sound detection signal module 15. When the test stand is pressed down, it actively enters the automatic test function and emits sound to detect the microphone detection signal.

[0051] The second is USB expansion unit 2: see attached... Figure 4 and appendix Figure 5 The USB expansion unit 2 is divided into a primary expansion unit 21 or a secondary expansion unit 22; see attached diagram. Figure 4 The primary expansion utilizes a 32-port USB hub 23; the 32-port USB hub 23 has more than 32 expansion ports; see attached... Figure 5 The secondary expansion utilizes USB expansion, i.e., through a USB hub or docking station, to expand a single USB interface into multiple ports; and is divided into two levels, with at least eight first-level hubs 21 and at least four second-level hubs 22.

[0052] The third is the group detection board unit 3: refer to the appendix. Figure 6 After passing through the USB expansion unit 2, the group detection board unit 3 simultaneously tests the product under test 6. Since the main control board unit 1 has a memory module 16, it can record the process, so it does not need to be connected to a computer and can automatically compare whether all output signals are consistent.

[0053] The fourth is computer connection unit 4: see attached document. Figure 7The computer connection unit 4 loads the control signals and feedback signals required by the group detection board unit 3 through the main control board unit 1. After loading, it can go offline. The loading process can be stored in the memory module 16 of the main control board unit 1. After loading, the main control board unit 1 can work independently offline.

[0054] The fifth is comparison unit 5, see appendix. Figure 8 When the comparison unit 5 is expanded to 32 channels via the USB expansion unit 2 on the main control board unit 1 and simultaneously controls the 32-channel group detection board unit 3 to test the product, the comparison unit 5 will check synchronously during the test. If an abnormality is found, it will be displayed in the comparison unit 5 with light 51, or indicated by flashing text on the display screen 221 of the first-level hub 21.

[0055] The preferred embodiment is that the main control board unit 1 has the following operating steps: S1 Test fixture pressure unit: Once the test fixture is successfully pressured, the test fixture actively uses RF433 and Bluetooth commands to put the controller under test into test mode and detect the corresponding parameters; the detected parameters and status information are transmitted through the UART between the board under test and the group detection. S2 Control: When the RF433 command is responded to, it is directly transmitted by the UART communication of the board under test. If the Bluetooth signal is successfully detected, the main control's transmit / receive Bluetooth signal module 12 transmits the Bluetooth transmit / receive detection pass to the U4 MCU. The U4 transmits the blue detection success information to the group detection board through the USB expansion unit 2.

S3 Power Supply: Power supply to the target board, with power management via U4; S4 Signal Control: Transmits 433MHz commands at low power to simulate long-distance communication. If the board under test can still receive the signal, the wireless receiving part of the board under test is good. S5 Comparison and Testing: The board under test enters the test mode, and the Bluetooth IC continuously detects the Bluetooth signal of a specific group. The group information corresponds one-to-one with the board information. S6 Test Result Judgment and Display: After entering the test mode, the audio sound unit emits a sound every 2 seconds. In the test mode, the test board detects the audio signal in real time. If the audio signal detected in the test mode reaches the threshold, the quality of the product is determined.

T3 Result Judgment: The 8 LED indicator lights correspond one-to-one with the panel being tested; red indicates abnormality, green indicates normal, and orange indicates testing in progress. The T4 judgment result shows that the real-time monitoring audio signal of the tested board has reached the threshold through the test mode, which determines the quality of the product; during the test, the comparison unit 5 will check synchronously, and an indicator light will be displayed if an abnormality is found.

[0057] The preferred option is, as shown in the appendix. Figure 9 When the main control board unit 1 receives the test fixture pressure signal, that is, when the main control board upper fixture 18 and the main control board lower fixture 19 are closed, the comparison unit 3 checks synchronously. If an abnormality is found, an indicator light will be displayed. If there is no abnormality, the next batch of products will continue to be burned.

[0059] The preferred embodiment is that the comprehensive testing device for wireless products includes a main control board unit 1, a USB expansion unit 2, a group detection board unit 3, a computer connection unit 4, and a comparison unit 5, as shown in the attached diagram. Figure 10 The main control board unit 1, USB expansion unit 2, computer connection unit 4, and comparison unit 5 can remain fixed; only the second group detection board unit 31 needs to be replaced to test different products under test 6, see attached diagram. Figure 11 Among them, product under test 6 includes product under test 61 with wireless function and product under test 62 without communication function.

[0060] In a preferred embodiment, the USB expansion unit 2 is divided into a two-level expansion or a one-level expansion; the one-level expansion utilizes a 32-port USB hub; it utilizes USB expansion, that is, through a USB hub or docking station, to expand a single USB port into multiple ports; commonly used configurations include 4-port and 8-port, either 4-port first then 8-port or 8-port first then 4-port; see attached diagram. Figure 12 To ensure the quality of the burning process, this is a power-powered model: an external power supply is required.

[0061] The core functions of a USB pinout (taking the most common USB 2.0 Type-A as an example) are power supply and data transmission. It has four pins, defined as follows: To put it simply: VCC and GND are like "wires" that provide power (such as charging a device), while D+ and D- are like "network cables" that transmit data (such as copying files).

[0062] The preferred solution is that the core of the color information control instruction module 14 is to achieve color control of the device or software by "specifying the target" + "defining the color parameters", which is common in programming, device control, design software and other scenarios. Taking a general format as an example: hardware device control (such as LED, screen); format: control [device ID], [color control function], [color parameters]; example: control LED1 to light up RGB(255,0,0) (light up LED1, the color is pure red, and the RGB values ​​correspond to the brightness of the red, green and blue channels respectively).

[0063] The preferred embodiment is a sound detection signal module 15, an electronic module used to detect sound signals and convert them into electrical signals, widely used in various applications requiring sound detection. Its working principle is as follows: the sound detection signal module typically includes a sound-sensitive element, such as an electret condenser microphone. When a sound wave reaches the microphone, it causes the electret diaphragm inside the microphone to vibrate, resulting in a change in capacitance and a corresponding small voltage change. This voltage change is then amplified and processed, converting it into an electrical signal that can be recognized by other devices. (See attached diagram.) Figure 13 The common types and characteristics of its sound detection signal module 15 are as follows: X1 LM386-based sound sensor module: It adopts the LM386 audio processing chip, which has the characteristics of low power consumption, adjustable gain, wide power supply voltage range, few external components and low total harmonic distortion. It can amplify audio signals, detect the presence or absence of ambient sound or determine the intensity of sound. The X2 LM393-based sound detection sensor module uses an LM393 comparator as a voltage comparator, comparing the signal with a preset threshold voltage to output a digital signal. The module also includes a potentiometer to adjust the sound detection threshold. X3 direct-reading noise decibel detection module: such as the AS11-x series from Alsen Technology, it is manufactured using a multi-point calibration process, with high detection accuracy and sensitivity. It features a unique independent packaging design for the stainless steel probe and reserves multiple output interfaces, making it suitable for various application integrations.

[0064] See attached document Figure 14 The sound detection signal module 15 has the following output methods: Y1 Analog Output: Usually represented by AO, it outputs the microphone's voltage signal in real time, with a voltage range of 0-5V, which can reflect continuous changes in sound intensity; Y2 Digital Output: Generally represented by DO, it outputs high and low level signals when the sound intensity reaches a certain preset threshold, used for simple sound presence or absence detection.

[0065] See attached document Figure 15 Example circuit diagram of sound detection signal module 15: It is a CA51F005 microcontroller with UART and PWM, controlled by main control board unit 1 via USB expansion unit 2, and the cycle and duty cycle can be arbitrarily configured; it has an integrated 12-channel 12-bit SAR ADC, which can analyze sound detection signals; the CA51F005 is an 8-bit microcontroller based on the 1T 8051 core launched by Shenzhen Jinrui Technology Co., Ltd.

[0066] The preferred embodiment is a Bluetooth signal transmitting / receiving module 12. A Bluetooth module refers to a basic circuitry set of chips integrating Bluetooth functionality, used for short-range 2.4G wireless communication. Its working principle is that when Bluetooth modules communicate, one must act as the master and the other as the slave. The master device initiates a call, first searching for nearby discoverable Bluetooth devices. Once found, it pairs with the slave device. After pairing, the master can initiate a call to the slave. After successful connection establishment, both parties can send and receive data. The following is a detailed introduction to the Bluetooth module: Classification Based on application and supported protocols, Bluetooth modules can be divided into Classic Bluetooth (BT) modules and Bluetooth Low Energy (BLE) modules. Classic Bluetooth modules are generally used for large data transmissions, such as voice and music; the biggest advantage of BLE modules is their reduced cost and power consumption, making them suitable for products with high real-time requirements, such as smart home devices and data transmission from sensor devices.

[0067] Based on protocol support, Bluetooth modules can be categorized into single-mode and dual-mode modules. A single-mode Bluetooth module supports only one Bluetooth protocol, while a dual-mode Bluetooth module supports both Bluetooth Classic and Bluetooth Low Energy protocols.

[0068] Based on application, there are Bluetooth data modules and Bluetooth audio modules, etc. Bluetooth data modules generally use BLE Low Energy Bluetooth modules, which have extremely low operating and standby power consumption; Bluetooth audio modules, because audio requires high bitrate data transmission, are more suitable for using BT Classic Bluetooth modules.

[0069] The preferred option is, as shown in the appendix. Figure 16 Here is an example of a BLE low-power Bluetooth module circuit diagram implementation: it includes a Bluetooth signal transmitting / receiving module 12 and a USB port 17; the main control board unit 1 can control the Bluetooth signal transmitting / receiving module 12 through the USB expansion unit 2 and then through the USB port 17.

[0070] The preferred option is that the 433.92MHz signal transmitting module 13 is described as follows: 433.92MHz (megahertz) is an unlicensed radio frequency band widely used in civilian and industrial short-range wireless communication, and its core is used for low-rate, low-power wireless data transmission.

[0071] The core application scenarios are as follows: Smart home control: Commonly found in remote switches, smart door locks, curtain motors, and light remote controls, this frequency band enables the transmission of commands between devices (such as switching on / off and adjusting modes).

[0072] Industrial / Agricultural Monitoring: Sensors (temperature and humidity, soil moisture, smoke sensors, etc.) transmit data to the receiving end without the need for wiring, making them suitable for outdoor or complex environments.

[0073] Wireless remote control devices: garage door remotes, electric door remotes, toy remote control cars, etc., utilize their short-range (usually tens to hundreds of meters) transmission characteristics to achieve control.

[0074] Security alarm system: Signal transmission between door and window magnetic sensors, human infrared detectors and alarm host, and the sending of wireless signals when an alarm is triggered.

[0075] The frequency band is characterized by its unlicensed use: no frequency band license needs to be applied for from the radio management department, reducing usage costs and making it suitable for civilian and small equipment.

[0076] Its transmission characteristics include better penetration (wall-penetrating ability) than high-frequency bands (such as 2.4GHz), but lower transmission rate (usually at the kbps level). It is more suitable for transmitting instructions and small-volume data, but not suitable for high-definition video and large file transmission.

[0077] Because it belongs to an open frequency band, it may interfere with other devices on the same frequency band (such as other remote controls or wireless doorbells), resulting in unstable signals.

[0078] Related hardware modules: The wireless module (transmit / receive module) based on the 433.92MHz frequency band is the core of its application. Common ones include super regenerative modules: low cost, low power consumption, suitable for short distance (within about 50 meters) and scenarios where stability requirements are not high (such as toy remote control).

[0079] The preferred option is to replace the 433.92MHz band with unlicensed communication bands, such as the 2.4GHz band, the Sub-1GHz band, and the 5GHz band. Unlicensed communication bands refer to bands that can be shared by an unlimited number of independent users without requiring a frequency license from a regulatory authority. The following are some common unlicensed communication bands: The 2.4GHz band, with a frequency range of 2400-2483.5MHz, is a globally unlicensed band. Its characteristics include high data rates (Wi-Fi up to 600Mbps, Bluetooth up to 2Mbps), and a typical transmission distance of 10-100 meters. However, it is significantly affected by wall attenuation, and the large number of devices using this band leads to considerable interference. It is primarily used in smart homes and consumer electronics, such as wireless routers, Bluetooth headsets, and smart bracelets.

[0080] Sub-1GHz band: The frequency range is between 300MHz and 1GHz, with specific frequency bands varying by country. This band offers ultra-long-distance transmission capabilities, reaching several kilometers in open environments, with strong penetration and diffraction ability, making it suitable for scenarios involving walls and underground transmission. However, the data rate is relatively low, typically less than 100kbps. Common applications include LoRa technology, which uses the 433MHz band in China and the 868MHz band in the European Union for remote IoT applications such as agricultural sensors and remote meters; technologies like Sigfox and Z-Wave also use this band.

[0081] 5GHz band: Some 5GHz bands are unlicensed, such as 5150-5850MHz. This band features high speed and low interference, but has a small coverage area. It is mainly used in areas such as high-definition video transmission and enterprise Wi-Fi. The US FCC is also considering opening up the 5350-5470MHz and 5850-5925MHz bands as unlicensed bands.

[0082] The preferred option is, as shown in the appendix. Figure 17 Here is an example of the circuit diagram implementation for the main control board unit 1: The main control board unit 1 is based on U4 (CA51F005T3), which can control the USB port using P13 / SCL and P14 / SDA. SW1 can be used to control the start test or repeat test, SW2 can be used to control the test of the product under test to be fully lit or fully off, SW3 can be used to control the test of the product under test to be fully lit in red, SW4 can be used to control the test of the product under test to be fully lit in green, and SW5 can be used to control the test of the product under test to be fully lit in blue.

[0083] The preferred option is, as shown in the appendix. Figure 18 Here is an example of the circuit diagram for module 13, which transmits a 433.92MHz signal: U3 (F166) is the core of the circuit. The crystal oscillator Y2 (13.56MHz) provides the oscillation source. The frequency multiplier circuit inside U3 (F166) generates 433.92MHz, which is then generated by L2, L3, L4, C12, C13, C14 and C15. The signal can be controlled by the main control board unit 1 for testing.

[0084] The preferred embodiment is that the present invention reduces the difficulty of worker testing by having 32 machines connected to one machine; simplifies the production testing process and reduces the time required for manual and product testing.

[0085] The preferred embodiment is that, with the present invention, after testing 32 targets simultaneously, a significant amount of working time is saved during synchronous testing. The average working time for testing one Bluetooth board is about 15 seconds, while synchronous testing can test 32 target boards in parallel, reducing the average testing time for each board to approximately 0.5 seconds; the more complex the product, the more time is saved.

[0086] In a preferred embodiment, after the present invention achieves a 1-to-32 configuration, the Bluetooth startup time of the product is converted into effective testing time during comprehensive testing. The test rack is slotted, allowing workers to begin distributing and packaging the boards while waiting for the entire board to complete testing, saving on board separation workstations. Furthermore, due to process optimization and product timing, certain processing fees are saved; costs are significantly reduced, decreasing the original testing cost from 0.15 yuan to 0.03 yuan; the more complex the product, the greater the savings.

[0087] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and inventive concepts of the present invention, should be covered within the protection scope of the present invention.
