Vibro-Meter VM600系列是一套专为大型关键旋转机械设计的振动监测与保护系统，其CPUM模块与保护卡（如MPC4）的协同工作，实现了对设备状态的实时监测与智能保护。以下从技术架构、功能实现及工业应用三个维度展开分析：

一、系统架构：CPUM模块的核心角色

模块化设计

VM600采用19英寸机架式结构，支持保护卡（MPC4）、状态监测卡（XMV16）等模块的灵活组合。CPUM作为机架控制器，负责：

通信管理：通过Modbus RTU/TCP或PROFINET协议与上位机（如VM600 MPSx软件）交互，实现保护卡的“一键式”配置。

数据处理：接收保护卡采集的振动信号（加速度、速度、位移等），执行数字滤波、阶次跟踪等算法，确保数据准确性。

监控输出显示

CPUM集成前面板显示器，实时呈现关键参数：

动态振动数据：如轴承振动幅值（μm）、振动速度（mm/s）。

转速信息：通过接近探头或磁脉冲传感器获取的轴转速（RPM）。

报警状态：可视化警报阈值（如ISO 10816标准限值）及当前触发状态（如红色警示灯）。

安全操作机制

警报重置（AR）按钮：允许操作人员在故障排除后手动复位报警，恢复系统正常运行。

热插拔支持：保护卡支持带电插拔，便于维护升级而不中断监测。

二、保护卡功能：MPC4的技术优势

多通道监测能力

动态通道：4通道同步采集振动信号，支持IEPE加速度传感器或涡流位移探头。

转速通道：2通道独立监测转速，兼容接近探头、磁阻传感器等。

智能信号处理

数字滤波：消除高频噪声干扰，提升信号信噪比。

阶次跟踪：分析振动信号与转速的关联性，识别特定频率成分（如轴承故障特征频率）。

可编程报警逻辑

阈值设定：用户可自定义振动幅值、转速偏差等报警触发条件。

输出扩展：报警信号可通过继电器卡（如IOC4T）驱动外部设备（如停机保护、声光报警器）。

三、工业应用场景与集成方案

关键设备保护

电力行业：监测燃气轮机、水轮发电机组，预防因振动超标导致的轴系损坏。

石油化工：保护离心压缩机、泵组，避免叶片断裂或轴承过热引发的连锁故障。

系统兼容性

与DCS/PLC集成：CPUM作为通信网关，将振动数据接入工厂控制系统，实现预测性维护。

软件支持：VM600 MPSx软件提供事件日志、趋势分析功能，辅助故障诊断。

扩展性与认证

扩展能力：单台VM600机架最多支持48通道，适用于多机组集中监控。

合规性：符合API 670标准，满足SIL 2安全完整性等级要求。

The Vibro Meter VM600 series is a vibration monitoring and protection system designed specifically for large critical rotating machinery. Its CPUM module and protection card (such as MPC4) work together to achieve real-time monitoring and intelligent protection of equipment status. The following analysis is conducted from three dimensions: technical architecture, functional implementation, and industrial applications:

1、 System Architecture: The Core Role of CPUM Module

Modular design

VM600 adopts a 19 inch rack mounted structure, supporting flexible combinations of modules such as protection card (MPC4) and status monitoring card (XMV16). As a rack controller, CPUM is responsible for:

Communication management: Interact with the upper computer (such as VM600 MPSx software) through Modbus RTU/TCP or PROFINET protocols to achieve "one click" configuration of the protection card.

Data processing: Receive vibration signals (acceleration, velocity, displacement, etc.) collected by the protection card, perform algorithms such as digital filtering and order tracking to ensure data accuracy.

Monitoring output display

CPUM integrated front panel display, real-time display of key parameters:

Dynamic vibration data: such as bearing vibration amplitude (μ m) and vibration velocity (mm/s).

Speed information: Shaft speed (RPM) obtained through proximity probes or magnetic pulse sensors.

Alarm status: Visual alarm threshold (such as ISO 10816 standard limit) and current triggering status (such as red warning light).

Security operation mechanism

Alarm Reset (AR) button: allows operators to manually reset alarms and restore normal system operation after troubleshooting.

Hot swappable support: The protection card supports live plugging and unplugging, making it easy to maintain and upgrade without interrupting monitoring.

2、 Protection card function: technical advantages of MPC4

Multi channel monitoring capability

Dynamic channel: 4-channel synchronous acquisition of vibration signals, supporting IEPE acceleration sensors or eddy current displacement probes.

Speed channel: 2-channel independent monitoring of speed, compatible with proximity probes, magnetic resistance sensors, etc.

intelligent signal processing

Digital filtering: eliminates high-frequency noise interference and improves signal to noise ratio.

Order tracking: Analyze the correlation between vibration signals and rotational speed, identify specific frequency components (such as bearing fault characteristic frequencies).

Programmable alarm logic

Threshold setting: Users can customize alarm triggering conditions such as vibration amplitude and speed deviation.

Output extension: Alarm signals can be driven by relay cards (such as IOC4T) to external devices (such as shutdown protection, sound and light alarms).

3、 Industrial application scenarios and integration solutions

Key equipment protection

Power industry: Monitor gas turbines and hydro generators to prevent shaft damage caused by excessive vibration.

Petrochemical industry: Protect centrifugal compressors and pump units to avoid chain failures caused by blade breakage or bearing overheating.

system compatibility

Integration with DCS/PLC: CPUM serves as a communication gateway to connect vibration data to the factory control system for predictive maintenance.

Software support: VM600 MPSx software provides event logging and trend analysis functions to assist in fault diagnosis.

Scalability and Authentication

Scalability: A single VM600 rack can support up to 48 channels and is suitable for centralized monitoring of multiple units.

Compliance: Complies with API 670 standard and meets SIL 2 safety integrity level requirements.
