Industrial Automation Usage Classes
Safety Class 0 Emergency action (always critical)
Control Class 1 Closed loop regulatory control (often critical)
Control Class 2 Closed loop supervisory control (usually non-critical)
Control Class 3 Open loop control (human in the loop)
Monitoring Class 4 Alerting Short-term operational consequence (e.g., event-based maintenance, asset tracking)
Monitoring Class 5 Logging downloading/uploading No immediate operational consequence (e.g., history collection, SOE, preventive maintenance)
Importance ofmessage timeliness increases

Mela Networks WSN Software
  • Enable users to rapidly and cost effectively
    deploy integrated, interoperable solutions for
    networked sensors across all device platforms,
    with centralized management and control
  • Build on Open Source Tools and Spring Framework
  • Spring framework, modular, maximal code reuse,
    wired by config files
  • Deployable to any standard J2EE
    container/application server, Apache Tomcat,
    Websphere, Oracle App Server, WebLogic
  • Hibernate and Data Access Object, support any
    database, mySQL, PostgreSQL, Oracle DB, SQL
    Server
  • Java and JSP, cross platform
  • Model View Controller (MVC) pattern, separate
    presentation from business logic from data, easy
    customization
  • Web services (SOAP) to interface with Enterprise
    applications
  • Structured XML, translators for any WSN vendor
    XML interface
  • AJAX, optimizing user experience
  • Plug and play with legacy industrial automation
    protocols, e.g. Modbus

10
Functionalities
  • Command and Control dashboard with summary alarm
    status
  • Easily apply user-defined business rules for
    immediate visibility and notification of
    exceptions   
  • Network topology
  • Monitor network health and connectivity
  • Data analysis and graphs
  • Easy and intuitive data access and trending
  • Configuration of device profiles and server
    settings
  • Easily configure and control a network of devices
    graphically
  • Web Services Interface
  • Transform raw data into actionable events and
    seamlessly integrate the events with existing
    enterprise execution systems.

REAL TIME LOCATION SYSTEM
  • Mesh network based
  • Use RSSI information
  • Proprietary algorithm using Bayesian networks
  • NO NEED for training
  • Self-learning network (location estimation is
    not affected by environmental changes)

Application Requirements
  • 2 years battery life (1 sec sensor sampling rate
    10 sec/packet)
  • High reliablity (gt 99.9)
  • Automatically picks clean channels to avoid
    interference
  • Edge node able to pick the best router to connect
    to the network
  • Mesh backbone should have redundancy, be
    self-healing
  • Fast reconnect time when parent down O (1) sec
  • Ease of deployment automatically pick clean
    channels, avoid interference
  • Hot standby base node to prevent single point of
    failure
  • Network provides sufficient health information,
    periodically on-demand
  • Customer can develop its own command and control
    applications to monitor the readings, configure
    devices through device profiles
  • Customer can develop sensor drivers easily
  • Separation of the network logic from the storage
    logic
  • Future battery powered routers with sensors
    attached to them.
