DSP Remote Monitor

DSP Compact Wireless Remote Monitor (WRM) system is an eight-channel unit used to analyze and control machinery condition caused by vibrations and other variables. It is a 24/7 controlling device that can communicate via the commonly used 802.11b/g industrial wireless network.
Each of its eight channels can measure: acceleration, velocity, displacement and envelope. It also has two AC channels and two channels dedicated to measure temperature or any input that conforms 4-20mA.

 

Data can be stored in the WRM memory or transmitted to the host machine analysis and follow-up software. This software includes an alarm system, which activates the digital alerts or relays, besides providing continuous warnings on the host PC screen.

This is ideal for

Critical and semi-critical machinery in the plant. Remote monitoring via Internet and remote failure analysis. Temporary imbalance detection and machine condition in production processes. Recurrent failure follow-up; suitable for troubleshooting problems. Bearing failure, cavitation and lubricant film performance follow-up detection. Machinery with poor maintenance due to difficult access. Long-term registration periods without connection. Unite allows for previously stored data dumping on command. Such as machinery on the field that maintenance personnel reach sporadically, like weekly or monthly.

Benefits

Quick implementation and start-up, which reduces installation costs. Additional system to predictive monitoring of machine condition 24/7 reliable and maintenance free monitoring system. Easy relocation and re-installation of the whole set. Easy Wi-Fi connection allows savings in network installations. Unit suitable for moving and difficult access machinery. Expandable system for condition monitoring coverage. Uses existing, already installed Wi-Fi infrastructure. Hardware and software adaptable to machinery and/or equipment production control system. Operation completely suitable for machines in motion. For example: mining trucks, train locomotives, subway cars, etc.

Overview

Easy software management of different variables such as mechanical vibration, pressure, RPM, temperature remote monitoring. Each monitoring module has 4-8 accelerometer channels, plus the auxiliary inputs for additional process variables and RPM registration. The system software can control up to 200 different WRMs, which allow to process more than 1,200 measurements simultaneously. The WRMs have relay outputs that can be used to activate instant alerts or activate kill switches if the thresholds configured in the software are exceeded. The point programmed measurements can be scalar or spectral; the variables are configurable individually in each point. The monitoring system is administered by the DSP Machinery Control software Configuration and Supervision, which will be responsible for defining the online monitoring system architecture and data follow-up.

Control and Analysis Software

DSP Machinery Control Software for WRM DSP Machinery Control software is designed for the organization and visualization of remote measurements delivered by remote monitoring WRM equipment. Measurement system thresholds, parameters and detailed analysis of results will be easily operated from this software. DSP Machinery Control software is designed to organize, execute, and save measurements performed using the WRM module. Every measurement the hardware captures can be seen on the main screen. This application offers several configurable views that enable, for instance, an online trend of an escalating value, or its analog (pie) or bar charts. Besides, it enables the viewing of spectral charts, waveform charts, and orbital diagrams, as configured.

Configuration

Load equipment and control points. The system enables the edition of point information, for example, choosing each bearing from a 29,000-bearing database that has already been pre-loaded. Every measurement the hardware captures can be seen on the main screen. This application offers several configurable views that enable, for instance, trending of an escalating value or its analog (pie) or bar charts. Besides, it enables the viewing of spectral charts, waveform charts, and orbital diagrams, as configured.

Setting

Once the equipment and the control points are set, the system enables the edition of point information, making it possible to select the data from the bearings at each point or to select one from the 29,000 bearings that the database has already loaded. Each view is user-configurable and it can be chosen to display different equipment or different points, making the information on the machinery condition visually available to the user. This information can be relayed to a smartphone. In spectral charts, the user can observe in a more detailed view every feature of each component in a vibration trend, and the application also offers tools for fast and user-friendly automatic analysis.

Tools for Analysis:

  • Amplitude and frequency of a component.
  • Highest peak locator.
  • Harmonics locator.
  • Bands locator.
  • Frequencies of bearing failure.
  • Harmonic frequencies of bearing failure.
  • Configuration of tools and thresholds.
  • Recording of spectrum as a JPG-image file.
  • Spectrum browsing based on dates.
  • Alarm mask configuration based on historical spectra.
  • Frequency and amplitude measurement unit converter.
  • Automatic marker for characteristic failure frequencies.
  • Automatic marker for gear frequencies.
  • Automatic marker for belt frequencies.

Points can be configured, and standard and special measurements, and measurement samplings can be defined in case they are not configured as a monitoring routine procedure. The multiple setting and point control tools allow the user to have full access to every variable that needs to be measured in order to isolate any failure the monitored equipment may be presenting.

Alarm system

Once defined, the alarms for each measurement will activate different types of commands, such as to enable NO – NC dry-contact relay for Alarm Systems. It is also possible to configure the system to automatically launch specific measurements upon the triggering of an alarm or, based on measurements already configured, to modify samples reducing the clearance time between measurements. The system delivers all tools for an operator at the control console to visualize the general status of vibrations on a critical machine and, at the same time, for an analyst to be able to diagnose based on the interpretation of vibrating signals using spectra, waveforms, and analysis tools. These tools, associated with their broad spectral sharpness (up to 25600 lines) and combined with bottom frequency scales (10-30 KHz), ensure a diagnosis capability at the correct level for determining any kind of rotating device the user may want to control.
