Description

technical field [0001] The invention relates to a signal detection and analysis system, in particular to a multifunctional and highly integrated portable signal detection device. Background technique [0002] Mechanical fault diagnosis technology is the most important guarantee for the safe operation of enterprise equipment and normal production. The diagnostic technology based on vibration characteristic analysis is the most widely used and most effective guarantee method in safe production. Early vibration analysis used special instruments, and these instruments required high-performance processors due to the large amount of signal analysis and processing. The special instruments were not only expensive, but also had fixed functions, poor versatility, and difficult upgrades. With the advancement of computer technology and the development of microcomputer-based vibration signal detection and analysis systems, due to their low cost, multiple functions, fast upgrades, and go...
