3. Working Principle
The machinery protection unit composed of Vibro-meter 200-510-041-021, 200-510-111-021 and MPC4 acts as the signal processing core and fault protection hub of the VM600 system. Following the closed-loop workflow of Signal Collection → Signal Processing → Fault Judgment → Alarm Linkage, it connects sensors, IOC4T input/output cards, CPUM control modules and external protection devices to realize real-time monitoring, fault diagnosis and emergency protection of key rotating machinery. Supported by advanced digital signal processing technology, it conducts automatic fault diagnosis and feeds back early warning information. The detailed working process is as follows:
Signal Collection Phase: MPC4 cards collect original monitoring signals from accelerometers, velocity sensors, proximity probes, displacement sensors, speed sensors and other transducers via built-in BNC interfaces, and provide stable power supply for sensors. It supports synchronous acquisition of 4 dynamic signals and 2 speed signals. After internal noise filtering, purified original signals are sent to signal processing units. The 16-bit high resolution and maximum 51.2kHz sampling rate ensure precise signal collection. The built-in OK system monitors sensor operating status in real time to timely detect sensor faults and wire breakage, and its storage capacity meets temporary storage demands of massive monitoring data.
Signal Processing Phase: MPC4 performs digital processing including filtering, integration, differentiation, rectification and order tracking on collected original signals to accurately extract key parameters such as vibration amplitude, phase, frequency and rotating speed, and analyze operating anomalies such as rotor unbalance, bearing wear and shaft misalignment. Processed parameters and analysis results are transmitted to CPUM modules via VME backplane bus for comprehensive analysis, and relevant signals are fed back to IOC4T cards to provide data basis for subsequent alarm and control actions. Its high-speed data processing ensures timely and accurate signal analysis.
Fault Judgment & Alarm Phase: MPC4 compares real-time monitored parameters with Alert and Danger thresholds preset via VM600 MPSx software. When values exceed alert thresholds, alert signals will be triggered and indicated by LED indicators, meanwhile alert information will be sent to CPUM and IOC4T cards. Once danger thresholds are exceeded or signal abnormalities are detected, emergency alarms will be activated immediately with preset alarm logics started. External audible & visual alarms will be driven through self-owned processing outputs or IOC4T cards to remind field staff of timely handling, realizing automatic fault diagnosis and accurate early warning.
Protection Linkage & Status Feedback Phase: While triggering danger alarms, MPC4 interlocks external protection devices such as trip switches and emergency braking units through relay outputs of IOC4T cards to cut off power supply or stop equipment operation rapidly, so as to prevent fault escalation and avoid equipment damage and safety accidents. Meanwhile, MPC4 collects real-time operating data including signal processing status, alarm status and power status, as well as linkage feedback signals from sensors and external devices, and uploads all data to CPUM modules for remote status monitoring and quick troubleshooting. Automatic power-on self-check further enhances overall system reliability.
