S-STation

S-STation is an integrated solution for you if you have multiple vibration analysis and diagnostic system infiSYS RV-200 of Shinkawa Electric deployed globally in your plants for real time monitoring. When a machine abnormal vibration is detected by infiSYS RV-200, S-STation also provides you with the capability of accessing the specific infiSYS RV-200 remotely for real time vibration analysis and diagnosis.

Product Overview

S-STation consists of the following software packages for integrated machine condition monitoring:

  • S-Server
    The core package installed on a dedicate server. S-Server collects and manages system configuration information and alarm/event data of all registered infiSYS RV-200.
  • S-Monitor
    The package installed on each operator’s computer. S-Monitor provides the user interface for machine condition monitoring based on the alarm/event information collected from all the infiSYS RV-200 registered in the same S-Server.
    Operators can access the related infiSYS RV-200 remotely to analyze or diagnose the reason of abnormal vibration of the related machines.
  • G-Monitor
    Compared with S-Monitor that can only monitor infiSYS RV-200 registered in the same S-Server, G-Monitor is a package installed on each G-Monitor operator’s computer, capable of monitoring and accessing up to 10 times more infiSYS RV-200 managed in different S-STations.
  • S-RS
    The package installed on each infiSYS RV-200. It collects and sends infiSYS RV-200 alarm / event information to S-Server, or provides the requested vibration data to S-Monitor or G-Monitor for trend display.
  • S-Editor
    A package used by System Integrators for creating user graphical display of S-Monitor and configuring S-STation.

User Benefits

  • Vibration conditions of rotating machinery in each plant can be monitored from remote support centers.
  • Maintenance engineers can analyze and diagnose the machine vibration abnormality remotely before or without going to the site along with the possibility of providing an early solution or technical support.
  • Fewer vibration expertise are able to deal with more vibration related machine troubles effectively by remote accessing the on-site infiSYS RV-200 from support center.

Features

Intensive monitoring of vibration focusing on alarm/event information of all rotating machinery

Vibration alarms/events of rotating machinery of infiSYS RV-200 are collected to and managed by S-Server to enable continuous monitoring and management of vibration status of all rotating machinery.

More efficient and safer system by decentralizing vibration analysis data

S-STation is cost effective and reduces the risk of system failure by keeping large amount of vibration data in each infiSYS RV-200 rather than consolidating them in one centralized host database. The distributed vibration data can be utilized effectively, as needed, for various vibration analysis and diagnosis with the support of remote access capability.

Early detection of machine abnormality by comparing vibration data of similar machines

Vibration data of rotating machinery of the same model collected by different infiSYS RV-200 systems at different locations can be displayed and compared on S-STation, allowing for an earlier and easier detection of machine abnormalities.

Display of process data from DCS

Process data (e.g. temperature/pressure) that serve as a reference for vibration analysis can be displayed on S-STation via an OPC server without the need to feed them via infiSYS RV-200.

Functional overview

Alarm monitoring

Alarm status of all registered infiSYS RV-200 systems are displayed on S-Monitor. These alarm information as well as comments added by operators are accumulated and managed in S-Server.

Trend display

Vibration data of multiple infiSYS RV-200 systems or the data of different time of a specific machine can be displayed simultaneously in the trend view for comparison of status of different rotating machines or of different time of the machine.

Remote access and operation

Remote accessibility from support center to an on-site infiSYS RV-200 system or other windows applications for real-time vibration analysis and diagnostics or operation. *
*NoMachine Enterprise Desktop software package by NoMachine is required.

Display of measurement value

Vibration and process values from infiSYS RV-200 systems or other systems via OPC server as well as graphical objects created using S-Editor can be displayed in S-Monitor/ G-Monitor.

CMS Overview

Rotating machinery that serves as the heart of plant equipments. The vibrations on these contain various important information. As a sensor manufacturer, SHINKAWA has always studied for and been there to protect rotating machinery. Using the proprietary program based on our expertise, we provide a system to analyze/diagnose the valuable data. Not only with the alarms in fault conditions, we support our customers with optimum scheduling of repair and maintenance by offering early detection of fault or abnormal condition, assumption of the cause or the area of the failure. SHINKAWA's CMS helps our customers make right decisions on the equipment investment to manage cost and risks. The results will be improved operation efficiency with safe and stable operation.

Failure prevention system CMS

SHINKAWA's CMS detects failure symptoms at early stages with monitoring, analyzing and diagnosing vibration from rotating machinery. Prevent failures/accidents contributes to plant’s efficient, continuous safe operations.

Benefits

CMS helps to realize safe operation by accurately analyze/diagnose the vibration on rotating machinery.

  • Reduce downtime with early detection
    Failure indicators are based on changes in vibration levels and characteristics. Knowing what is going on, allows for proactive maintenance where downtime can be scheduled minimizing impact to production and profits.
  • Optimize production schedule
    Production efficiency drives the profitability of a plant. Maintenance of the equipment optimizes time and costs resulting in managing profit risk.
  • Reliable and efficient maintenance
    Proper sensor technology with necessary sophistication and precision provide the raw data for accurate analysis and diagnostics. This data allows for intelligent, timely and cost effective maintenance decisions by plant personnel.
  • Reduce total maintenance costs by moving from TBM to CBM
    TBM is an excellent approach to servicing equipment; however, it is not the most cost efficient. Utilizing CBM is a proactive way to reduce costs, became more efficient, and have better knowledge of the equipment health.
    TBM : Time Based Maintenance
    CBM : Condition Based Maintenance
  • Allow empirical maintenance knowledge to be passed on
    Maintenance professionals have “know-how” or empirical knowledge which is difficult to pass on. Having real life data with analysis helps create the “know-how” so any level of experience can benefit from the data. It is a scientific approach and reduces learning curves.

Capture, analyze, diagnose

Sensor data is continuously collected for analysis and diagnosis on the equipment. SHINKAWA’s original software is based on our expertise in sensor technology and vibration experience. Our customers know this and rely on our high quality products.
