Description

Technical Field

[0001] The present invention relates to the field of artificial intelligence technology, and more specifically, to a crystal oscillator quality monitoring system based on artificial intelligence. Background Art

[0002] As a high-precision and high-stability oscillator, crystal oscillator is widely used in various oscillation circuits such as color TVs and computers, as well as in frequency generators in communication systems, to generate clock signals for data processing equipment and provide reference signals for specific systems. It has a significant position in the field of modern electronic technology. Its excellent clock signal generation capability enables it to play a key role in various applications. Therefore, quality monitoring of crystal oscillators has become a vital issue.

[0003] Traditional crystal oscillator quality detection systems generally include a time zone division module, a sub-zone parameter acquisition module, and a sub-zone data analysis and processing module. The time zone division module is used to divide the working time of the crystal oscillator into n equal parts, which is convenient for studying the information generated by the crystal oscillator in each time period; the sub-zone parameter acquisition module is used to obtain the parameters in the divided time sub-zones, and it is convenient and accurate to collect through multimeters, oscilloscopes, etc., and provide a large amount of data; the sub-zone data analysis and processing module analyzes and processes the collected data through artificial intelligence to understand key information such as the frequency stability of the crystal oscillator and the temperature during operation, providing a scientific basis for quality monitoring.

[0004] However, there are still some shortcomings in its actual use. For example, in the sub-region parameter acquisition module, the data accuracy is not enough, and the parameters acquired are often a single frequency. Therefore, in the sub-region data analysis and processing module, most of the traditional artificial intelligence crystal oscillator quality monitoring methods only monitor the frequency stability and power consumption, and rarely mention the internal temperature of the crystal oscillator. In fact, the internal temperature of the crystal oscillator is extremely important. For example, with the needs of scientific and technological development, crystal oscillators are used more and more in aircraft. When flying at high altitudes, aircraft often experience drastic changes in external high and low temperatures, which seriously affects the stability of the crystal oscillator.
