Technical Field
[0001] The utility model relates to the technical field of resonance test, in particular to a series resonance test device with a digital display screen. Background Art
[0002] A series resonance test device with a digital display screen adopts a digital display screen to display test information clearly and intuitively. The automatic resonance detection function uses advanced digital signal processing technology to improve test accuracy and efficiency. In addition, the scalability of the device enables it to connect external sensors and accessories to meet different test needs. Its control interface is optimized and easy to use. High-precision and stable measurement performance ensures the reliability of test results. Enhanced anti-interference ability makes it suitable for complex environments. An existing variable frequency series resonance test device (publication number: CN207020273U) has the following disadvantages and needs further improvement.
[0003] 1. Traditional equipment does not have a high-contrast LCD display and backlight adjustment function. The display content is difficult to recognize in a strong light environment, which affects the user's acquisition of test information. In addition, the display layout of traditional equipment may be unreasonable, and the display of test parameters and results is not clear, which brings inconvenience to users. In a strong light environment, the numbers and characters on the display of traditional equipment may be blurred or even completely invisible. This will cause great inconvenience to users and even lead to test errors. In addition, the display layout of traditional equipment may be unreasonable, and the test parameters and results are mixed together, and users need to spend a lot of time to find the required information. Therefore, there is an urgent need for a resonance test device with a digital display design.
[0004] 2. Traditional equipment does not have the ability to use analog-to-digital converters and digital signal processors to track the changes in the excitation signal and the response signal of the component under test in real time. Traditional equipment uses analog circuits for resonant frequency detection, which is easily affected by environmental noise and human factors, resulting in low test accuracy. Traditional equipment requires manual adjustment of the excitation frequency and observation of changes in the response signal to determine the resonant frequency. The process is cumbersome and time-consuming, and the test efficiency is low. The resonant frequency detection of traditional equipment depends on the experience and judgment of the operator. The test results of different operators may vary greatly, and the human factor has a greater impact. Therefore, there is an urgent need for a resonance test device with automatic resonance detection.
[0005] 3. Traditional equipment does not have the ability to provide standardized interfaces, support multiple sensors and accessories, and provide software development kits. Traditional equipment has fixed functions and cannot be flexibly expanded, making it difficult to meet different test requirements. The interfaces and protocols of traditional equipment are not unified, and the compatibility with other equipment is poor, which brings inconvenience to users. Traditional equipment usually does not provide software development kits, and users cannot perform secondary development on the equipment, which limits the scope of application of the equipment. Therefore, there is an urgent need for a scalable resonance test device. Utility Model Content
