IV. Working Principle
The VIBRO-METER VM600 CPUM 200-595-067-114 main control module operates based on the multi-channel synchronous sampling + high-precision data operation + spectrum and order analysis + multi-level logic judgment + intelligent protection output + full-status traceability principle. As the core hub of the VM600 system, it overall manages the whole process of system signal acquisition, data processing, status judgment and protection output. The workflow includes six core links: signal reception and integration, data preprocessing, high-precision operation analysis, fault logic judgment, alarm and protection output, and data storage and upload.
During normal system operation, the CPUM module synchronously receives equipment vibration and speed analog data transmitted by each IO card through the rack backplane bus, integrates original data of 16 dynamic channels and 4 speed channels, and eliminates on-site electromagnetic interference and signal distortion through multi-stage digital filtering, signal shaping and noise reduction preprocessing to restore real equipment operating condition data. Relying on the 24-bit high-precision operation core, it calculates basic parameters such as vibration amplitude, effective value, peak-peak value, phase, speed and fluctuation, and analyzes equipment frequency domain characteristics and variable-speed operation rules through FFT high-speed spectrum algorithm and order tracking algorithm.
After operation, the module compares real-time parameters with preset alarm, interlock and shutdown thresholds in the system. When parameters are within the normal range, it continuously uploads equipment operation status and trend data; when parameters exceed the limit, signals are abnormal or fault features are identified, it immediately triggers corresponding levels of alarm, interlock or shutdown protection commands, synchronously locks fault status and records fault spectrum and parameter data for accurate fault traceability. Meanwhile, the module responds to local key operations and remote communication commands in real time to complete parameter setting, status query, fault reset and program upgrading, realizing integrated intelligent management of equipment condition monitoring, fault diagnosis, safety protection and intelligent operation and maintenance.
