Description

Technical Field

[0001] This utility model relates to the field of radio frequency testing technology, and in particular to an automated radio frequency testing system. Background Technology

[0002] Currently, the specific testing method for mobile phone RF receiving sensitivity is as follows: First, the phone under test is placed in a shielded box. Then, the phone is set to a screen-off state to measure the RF receiving sensitivity of each channel across various frequency bands in this state. After completing the screen-off test, the phone's state needs to be manually switched to a screen-on state, such as live wallpaper mode (where the phone screen displays a dynamically changing wallpaper), front camera preview mode (where the screen previews the image using the front camera), or rear camera preview mode (where the screen previews the image using the rear camera). The above test process needs to be repeated for each screen-on state to measure the phone's RF receiving sensitivity value under each screen-on state.

[0003] After completing the RF receiver sensitivity tests under various screen-on states, the RF receiver sensitivity values ​​measured under each screen-on state were compared with those measured under the screen-off state. According to relevant technical standards and requirements, the difference between the two values ​​must be strictly controlled within the range of 3-5 dB to ensure that the phone's RF receiver performance under different states meets the established standards.

[0004] However, the existing testing method has revealed several problems in practical applications. The most prominent issue is the need for manual switching of the phone's network standard after completing a network standard test. This not only increases the workload of testers but also increases the risk of human error, affecting the accuracy of the test results. Furthermore, when the phone's battery is depleted, it must be removed from the shielding box for charging before being reinserted for further testing. This process is cumbersome and time-consuming, resulting in extremely low overall testing efficiency. More importantly, the entire testing process is highly dependent on manual processing, making unattended automated testing impossible and failing to meet the demands of large-scale, high-efficiency testing.

[0005] Therefore, in order to improve testing efficiency, ensure the accuracy and reliability of test results, reduce labor costs, and achieve automation and intelligence in the testing process, it is imperative to comprehensively and deeply improve and optimize existing technologies.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please refer to Figure 1 This utility model provides an automated radio frequency (RF) testing system. The system has a scientifically sound overall architecture, with all components working collaboratively. It aims to achieve efficient, accurate, and intelligent testing of the RF receiver sensitivity of devices under test (such as mobile phones, POS machines, tablets, etc.; this embodiment uses a mobile phone as an example). Its specific components include a shielding box 1, a testing device 2, and a computer 3.

[0040] The shielding box 1 employs a special material and structural design, possessing signal shielding capabilities and creating a pure testing environment for the mobile phone under test, virtually unaffected by external electromagnetic interference. By housing the mobile phone under test inside the shielding box 1, interference from the complex external electromagnetic environment on the phone's radio frequency signal reception is effectively avoided, thus ensuring that subsequent test results accurately reflect the phone's own radio frequency reception performance.

[0041] Test device 2 is the core equipment for RF testing of the entire system. Test device 2 can comprehensively and meticulously test the RF receiving sensitivity of the mobile phone housed in shielded box 1 according to the set test parameters and standards. It can accurately capture the RF signal reception of the mobile phone under different network standards, frequency bands, and channels, and record and analyze the relevant data in digital form, providing detailed and accurate basis for subsequent evaluation of the mobile phone's RF performance.

[0042] Computer 3 plays a crucial role in the overall control of the system. It connects to both the testing device 2 and the mobile phone under test, achieving precise control of both through specialized software and a control system. Specifically, Computer 3 can automatically control the mobile phone to switch network standards according to preset test procedures and requirements, such as switching from 2G to 3G, 4G, or even 5G networks, ensuring comprehensive testing of the phone's RF reception performance under different network standards. Simultaneously, Computer 3 can precisely control the phone's state transitions, such as switching from a screen-off state to a screen-on state, or switching to various states like live wallpaper, front camera preview, and rear camera preview, to meet the testing needs of the phone's RF reception sensitivity in different usage scenarios. Furthermore, Computer 3 can intelligently control the connection and disconnection of the phone's charging. Based on the phone's battery level and test progress, it automatically determines whether charging is needed and connects or disconnects the charging circuit at the appropriate time, avoiding test interruptions due to insufficient battery power. It also eliminates the need for testers to frequently remove the phone for charging, greatly simplifying the testing process. Furthermore, the computer 3 can precisely control the opening and closing of the testing device 2, automatically starting the testing device 2 when testing is required and shutting it down promptly after testing is completed, effectively saving energy and equipment wear and tear.

[0043] In summary, the RF testing automation system provided by this utility model successfully achieves full automation of mobile phone RF receiver sensitivity testing by organically integrating and coordinating the shielding box 1, testing device 2, and computer 3. The automatic control function of computer 3 eliminates the need for manual intervention during network mode switching and state transitions, avoiding errors and mistakes that may arise from manual operation. This significantly improves the accuracy and reliability of the test, ensuring that the test results truly and objectively reflect the mobile phone's RF performance. Simultaneously, the system's automatic mobile phone charging function makes the testing process more continuous and smooth, eliminating the need for frequent phone charging, greatly simplifying the testing process, shortening the entire testing cycle, and effectively improving testing efficiency. Furthermore, the unattended automated testing mode implemented by this system greatly reduces reliance on manual labor, reduces labor costs, and easily meets the needs of large-scale, high-efficiency testing. Whether conducting performance testing on a large number of prototypes during the mobile phone R&D stage or performing quality inspections on products during production, this system provides an efficient, accurate, and intelligent solution, positively promoting the development of the mobile phone RF performance testing field.

[0044] Please refer to Figure 2In one embodiment of this invention, the testing device 2 includes a testing instrument 21 and a testing antenna 22, which work closely together to complete the task of accurately testing the radio frequency reception sensitivity of the mobile phone.

[0045] The test antenna 22 is housed within the shielding box 1. The shielding box 1 possesses excellent electromagnetic shielding performance, creating a relatively pure working space for the test antenna 22, free from interference from complex external electromagnetic environments. As a key component for signal reception and transmission, the test antenna 22 can stably and accurately receive radio frequency signals emitted by the mobile phone within the shielding box 1. Simultaneously, it can transmit radio frequency signals of specific frequencies and intensities to the mobile phone according to test requirements, thereby ensuring that the signal transmission and reception process is unaffected by external factors throughout the entire test.

[0046] The testing instrument 21 plays a crucial role in the core control and data processing of the entire testing device 2. It is connected to both the testing antenna 22 and the computer 3. The connection to the testing antenna 22 enables the testing instrument 21 to acquire, in real-time and accurately, the mobile phone radio frequency signal data received by the antenna. This data includes key information such as the mobile phone's radio frequency reception strength and signal quality under different standards, frequency bands, and channels. Leveraging its powerful signal processing capabilities, the testing instrument 21 performs preliminary analysis, organization, and preprocessing of this raw data, transforming it into a more readable and comparable data format.

[0047] Meanwhile, the connection between the testing instrument 21 and the computer 3 enables further data transmission and in-depth processing. The computer 3, as the intelligent control center of the entire testing system, communicates and interacts with the testing instrument 21 through specialized software programs. It can send various test commands to the testing instrument 21, controlling it to operate according to preset test procedures and parameters, such as setting the test frequency range and signal strength threshold. Furthermore, the computer 3 can receive pre-processed data transmitted from the testing instrument 21 and use advanced algorithms and models to conduct in-depth analysis of this data, thereby generating detailed test reports and evaluation results regarding the mobile phone's RF receiver sensitivity. These results not only intuitively reflect the mobile phone's RF performance under current test conditions but also provide important reference information for mobile phone research and development, production, and quality inspection.

[0048] In summary, in this embodiment, the testing device 2, through the organic combination of the testing instrument 21 and the testing antenna 22, and the collaborative work with the computer 3, forms an efficient, accurate, and intelligent testing system. This system can comprehensively and accurately complete the testing task of mobile phone radio frequency receiving sensitivity, providing strong technical support for the optimization and improvement of mobile phone radio frequency performance.

[0049] Please refer to this again. Figure 1-2 In one embodiment of this invention, the test instrument 21 is connected to the test antenna 22 via a coaxial cable 4.

[0050] It should be noted that coaxial cable 4, as a type of cable widely used in the field of radio frequency signal transmission, has unique structural characteristics. It consists of an inner conductor, an insulating medium, an outer conductor, and an outer sheath. The inner conductor is usually made of a highly conductive metal material, such as copper, for transmitting radio frequency signals; the insulating medium isolates the inner and outer conductors and maintains certain electrical properties; the outer conductor is generally composed of a metal braided mesh or metal foil, which not only shields and protects the inner conductor, reducing the impact of external electromagnetic interference on signal transmission, but also forms a transmission line with the inner conductor to achieve effective signal transmission; the outer sheath is mainly used to protect the entire cable from mechanical damage and environmental corrosion.

[0051] In this embodiment, the test instrument 21 is connected to the test antenna 22 via a coaxial cable 4, ensuring stable and efficient transmission of radio frequency (RF) signals between them. During testing, the test antenna 22 is responsible for receiving RF signals emitted by the mobile phone or transmitting RF signals of specific frequencies and intensities to the mobile phone. These signals carry crucial information about the mobile phone's RF performance. The coaxial cable 4, with its excellent transmission characteristics, minimizes signal attenuation and distortion during transmission. Its low-loss characteristics allow the RF signal to maintain high strength and quality over long transmission distances, ensuring that the test instrument 21 receives accurate and reliable signal data. This provides a reliable basis for subsequent precise analysis and evaluation of the mobile phone's RF receiving sensitivity.

[0052] Meanwhile, the excellent shielding performance of coaxial cable 4 is also crucial. In complex electromagnetic environments, various interference signals may exist. Coaxial cable 4 can effectively shield these external interferences, preventing them from interfering with or affecting the internally transmitted radio frequency signals, thus further ensuring the purity and stability of signal transmission. This is of great significance for obtaining accurate and reliable test data and improving the accuracy and reliability of the entire test system.

[0053] In addition, the coaxial cable 4 has a certain degree of flexibility and mechanical strength, which facilitates wiring and connection operations during actual installation and use. It can be bent and adjusted according to the actual needs of the test site, making it convenient to place the test antenna 22 in a suitable position inside the shielding box 1. At the same time, it can also ensure a firm and reliable connection with the test instrument 21, and is not prone to problems such as loosening or poor contact, thereby ensuring the stable operation of the entire test device 2.

[0054] In summary, in this embodiment, the test instrument 21 is connected to the test antenna 22 via the coaxial cable 4. This is a specially designed and optimized option that provides strong assurance for the accuracy and reliability of mobile phone radio frequency reception sensitivity testing and helps to achieve efficient and stable operation of the entire test system.

[0055] Please refer to this again. Figure 1-2 In one embodiment of this invention, the connection and related control design between the computer 3 and the mobile phone are further designed. The computer 3 establishes a connection with the mobile phone via a USB cable 5. This connection method is widely used in the current field of electronic device communication and has many significant advantages. The USB cable 5, as a standardized data transmission and power supply cable, features high transmission speed, strong compatibility, and ease of use. Through the USB cable 5, the computer 3 can not only achieve stable and efficient data transmission with the mobile phone but also provide the necessary power support to the mobile phone, meeting its power supply needs during testing.

[0056] However, to further optimize the testing environment and avoid unnecessary interference, a relay 6 is specifically installed on the USB cable 5. In this embodiment, the relay 6 is connected to the computer 3, and its operating state is completely controlled by the computer 3. This design allows the computer 3 to precisely control the on and off states of the relay 6 according to the actual testing requirements.

[0057] Specifically, when the testing process requires charging the phone, switching the phone's network standard, or changing the phone's state (such as switching from screen-off to screen-on), computer 3 will issue corresponding control commands to activate relay 6. At this time, USB cable 5 forms a complete electrical path, allowing computer 3 to charge the phone or send control signals to the phone to switch network standards and states. This process is precise and rapid, ensuring that the testing operation proceeds smoothly according to the preset procedure.

[0058] At other times, when the above operations are not required, computer 3 will control relay 6 to disconnect. This is significant because when USB cable 5 is continuously conducting, it may introduce potential interference into the circuit. For example, USB cable 5 itself may emit electromagnetic radiation, or its electrical characteristics may have a slight impact on the test signal. Although these interferences may be weak, they can have a significant impact on the test results in mobile phone RF receiver sensitivity tests, which require extremely high accuracy. By disconnecting relay 6 when unnecessary, test interference caused by USB cable 5 conduction can be effectively avoided, providing a cleaner and more stable electromagnetic environment for testing, thereby further improving the accuracy and reliability of the test.

[0059] In summary, in this embodiment, the computer 3 is connected to the mobile phone via a USB cable 5, and a relay 6 controlled by the computer 3 is installed on the USB cable 5. This ingenious design fully considers the actual needs and possible interference factors during the testing process. By controlling the on and off of the relay 6, effective control of operations such as mobile phone charging, network mode switching, and state switching is achieved, while minimizing test interference.

[0060] In one embodiment of this invention, the design of the shielding box 1 fully considers the convenience and functionality of connecting with mobile phones and external devices, and a USB interface is specially provided. This design provides key support for the stable operation and data interaction of the entire test system.

[0061] From a structural layout perspective, one end of the USB cable 5 is connected to the USB interface on the shielding box 1. This connection method has multiple important implications. On the one hand, the USB cable 5 serves as a bridge for data transmission and power supply between the computer 3 and the mobile phone. Its connection to the USB interface on the shielding box 1 makes the entire connection line more organized and orderly. In the testing environment, various cables are intricately intertwined; this organized connection helps reduce mutual interference between cables and lowers the probability of malfunctions such as poor contact caused by cable tangling or pulling, thereby improving the stability and reliability of the entire testing system. On the other hand, the shielding box 1 itself possesses excellent electromagnetic shielding performance; its outer shell can effectively block the intrusion of external electromagnetic signals. When the USB cable 5 is connected to the USB interface on the shielding box 1, the shielding box 1 can provide a certain degree of shielding protection for the USB cable 5, reducing the transmission of external electromagnetic interference to the mobile phone or computer 3 through the USB cable 5, further ensuring the accuracy and stability of data transmission during the testing process.

[0062] The mobile phone is connected to the other end of the USB interface. This connection method allows the mobile phone to seamlessly interface with the control signals and power supply of the computer 3 transmitted via USB cable 5. During the test, the computer 3 needs to send various control commands to the mobile phone, such as switching network standards and changing operating status. These commands are transmitted to the mobile phone via USB cable 5, and the mobile phone can quickly respond accordingly to meet the test requirements. Simultaneously, when charging the mobile phone is required, the computer 3 can provide stable power support through USB cable 5, ensuring that the mobile phone always has sufficient power during the test and avoiding test interruptions due to insufficient power.

[0063] In summary, in this embodiment, the shielding box 1 is equipped with a USB interface and is connected to the computer 3 and the mobile phone respectively via USB cable 5. This design cleverly combines the electromagnetic shielding function of the shielding box with the convenient connection characteristics of the USB interface, providing an efficient, stable, and reliable testing environment for mobile phone radio frequency receiver sensitivity testing, which helps to improve the accuracy and efficiency of the test.

[0064] In one embodiment of this invention, a positioning component is provided inside the shielding box 1;

[0065] The positioning component is used to fix the mobile phone in a preset position.

[0066] It should be noted that during RF receiver sensitivity testing, the relative position and distance between the mobile phone and the test antenna significantly affect the test results. Even a slight positional shift or distance change can alter the strength of the RF signal received by the phone, thus causing deviations in the obtained receiver sensitivity data. The main function of the positioning component is to fix the phone in a preset position, ensuring that the relative position and distance between the phone and the test antenna remain constant throughout the test, eliminating test errors introduced by positional changes, and improving the accuracy and repeatability of the test results.

[0067] Optionally, the positioning component includes adjustable clamps and / or supports, a design that takes into account the diversity of different models and sizes of mobile phones as well as the flexibility of testing requirements.

[0068] It's important to note that the clamps are typically made of high-strength, wear-resistant materials to ensure a secure grip on the phone. Their adjustability is reflected in several aspects; for example, the clamp's opening width can be flexibly adjusted to accommodate the width of the phone, ensuring a stable hold for both small smartphones and larger phablets. Furthermore, the clamping force can be controlled via an adjustment mechanism, ensuring the phone is firmly secured without damaging the casing or internal components due to excessive clamping. The clamps may also feature angle adjustment, allowing the phone to be tilted at different angles according to testing requirements, simulating various postures of the phone in real-world use, thus providing a more comprehensive test of the phone's RF reception performance under different postures.

[0069] The stand provides a stable support platform for the mobile phone, and its adjustability is also highly versatile. The height of the stand can be flexibly adjusted according to the internal spatial layout of the shielding box 1 and the height of the test antenna, ensuring that the mobile phone and the test antenna are at the optimal alignment height, and ensuring that the radio frequency signal can be transmitted between the mobile phone and the test antenna in the best way. The horizontal position of the stand can also be finely adjusted to accurately place the mobile phone on the preset test point. In addition, some stands also have a rotation function, which allows the mobile phone to rotate around the vertical axis, facilitating the testing of the mobile phone's radio frequency reception characteristics in different directions, further expanding the dimensions and scope of testing.

[0070] Please refer to Figure 3 In one embodiment of this invention, the system further includes an alarm device 7;

[0071] The introduction of this alarm device 7 provides extremely important protection for the stable operation of the entire testing system and the handling of abnormal situations.

[0072] In terms of connectivity, the alarm device 7 is connected to the computer 3. As the core control unit of the entire testing system, the computer 3 undertakes crucial tasks such as data processing, analysis, and command issuance. It can monitor and analyze various data generated during the testing process in real time, accurately determining whether the test results are normal and whether the equipment is operating normally based on pre-set standard parameters and judgment logic. The connection between the alarm device 7 and the computer 3 allows the computer 3 to promptly transmit signals to the alarm device 7 when it detects an anomaly, triggering the corresponding alarm action.

[0073] The main function of alarm device 7 is to quickly issue an audible and visual alarm signal when computer 3 detects abnormal test results or equipment malfunction. Abnormal test results refer to test data obtained during the actual test that exceeds the preset normal range. Equipment malfunction encompasses various problems that may occur in different components of the test system, such as accuracy deviations in test instrument 21, damage to test antenna 22, or decreased shielding performance of shielding box 1. Once computer 3 detects these abnormalities, alarm device 7 will immediately activate the audible and visual alarm function.

[0074] Audible and visual alarm signals are intuitive and eye-catching. Audible alarms, with their varying frequencies and tones, quickly attract the operator's attention, effectively conveying alarm information even in noisy working environments. Visual alarms, typically using flashing lights such as red warning lights, provide a strong visual impact, enabling operators to detect anomalies immediately. This combination of audible and visual alarms ensures that operators are promptly informed and can take appropriate measures when abnormal test results or equipment malfunctions occur, such as stopping the test, inspecting the equipment, and troubleshooting. This prevents the anomaly from escalating and causing more serious consequences, ensuring the smooth progress of testing and the accuracy of test results.

[0075] In summary, in this embodiment, the alarm device 7, which is connected to the computer 3, adds a reliable safety barrier to the entire testing system by issuing audible and visual alarm signals when abnormal test results or equipment malfunctions are detected. This improves the reliability and stability of the system and is of great significance for ensuring the high-quality completion of testing work.

[0076] Although this invention uses terms such as shielding box and computer frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0077] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model.
