Definitions

  • Conventional environmental monitoring systems provide the ability to monitor various types of environmental instruments in order to detect changes in environmental conditions.
  • environmental monitoring systems designers have created systems that include a plurality of remotely operable radiation detection instruments that individually sense radiation levels in a relative vicinity and report detected radiation levels to a centralized computer system for display to a human operator.
  • the centralized computer system might contain, for example, a graphical user interface that identifies each individual radiation detection instrument within the system along with an associated radiation level sensed by that instrument.
  • Such conventional systems provide the ability for an operator to set alarm thresholds that allow the system to identify situations in which the radiation level sensed by a particular radiation detection instrument exceeds a certain value and in response, provide an alarm indication to a human operator.
  • Conventional environmental monitoring systems suffer from a variety of deficiencies.
  • such conventional environmental data processing systems lack a modular design that provides for easy adaptability and expandability for the addition of alternative types of environmental monitoring devices or instruments to be integrated into such systems.
  • conventional environmental monitoring systems such as those described above are typically limited or restricted to processing certain types of data that must conform to certain formats for device data collection.
  • an environmental monitoring system produced from vendor A might only efficiently operate using vendor A's environmental detection instruments or with other vendor's measurement instruments that conform to Vendor A's communications protocol. It is often difficult or impossible to integrate environmental detection instruments from other vendors into such a system if those devices do not communicate using on of the accepted protocols.
  • the vendor of the conventional systems typically collets customer request for new features (e.g., new processing operations or calculations on collected data) and releases a new version of the environmental monitoring system, such as a new release of the software program, that is capable of communicating with existing devices as well as new devices integrated into the new release of the software.
  • the new release may also support some of the requested processing operations. This is problematic since it requires upgrading from an earlier release to a new version of the environmental monitoring computer system and software in order to obtain the desired processing features and device compatibility and can often be challenging task.
  • conventional systems do not provide an open modular software design, adding new processing features is often not worth the trouble.
  • Embodiments of the invention significantly overcome such deficiencies and provide a flexible, dynamic and expandable environmental monitoring system that provides an open and modular architecture that is fully expandable to accommodate different types of devices and monitoring instruments, data formats, instrumentation protocols, processing operations and operator views.
  • embodiments of the invention provide a software-based design that supports the use of modular plug- ins for various processing tasks that include communication with environmental monitoring instruments, processing and conversion of raw data into measurement data, and storage and presentation of such raw data and measurement data within, for example, a database or upon a graphical user interface for viewing by a human operator of the environmental monitoring system provided in accordance with embodiments of the invention.

  • the radiation data collection plug-ins collect and forward raw radiation data to the data engine core where this raw radiation detection data is routed via a route manager, for example, to a radiation conversion plug-in that can convert the raw radiation detection data into measurement data. Once converted to measurement data, the radiation data conversion plug-in then forwards this measurement data back to the data engine core.
  • the system of the invention routes raw data collected from environmental monitoring instruments between plug-ins using a routing mechanism defined within the data engine core.
  • the data engine core configured in accordance with embodiments of the invention provides the ability to define view definitions.
  • View definitions generally identify measurement data of interest to specific plug-ins that have registered an "interest" with a particular view definition.
  • the measurement data is returned to the data engine core which then tests each view definition to see if any defined view definitions identify the radiation measurement data as being applicable to that view definitions.
  • view definitions define filters for measurement data of interest to plug-ins that have registered to have an association or interest in that view definitions. If measurement data matches any view definitions, the data engine core transports, forwards or otherwise provides that measurement data to all plug-ins that have registered an interest in that view definition. In this manner, the radiation measurement data is disseminated to each plug-in for subsequent processing.
  • Plug-in processing can include operations such as data collection from instruments and partial conversion of raw data to measurement data.
  • Conversion plug-ins can receive a stream of raw data routed from the data engine core (i.e., the raw data being previously collected and forwarded from a data collection plug-in to the data engine core) and can perform conversion of the raw data to measurement data.
  • Display plug- ins can control operation of graphical user interfaces and display plug-in processing can include, for example, displaying the measurement data in a graphical user interface for viewing by human operator or any other type of processing.
  • Plug-ins are capable of defining custom view definitions and are also capable of registering for existing view definitions defined by other plug-ins.
  • the architecture of the environmental monitoring system provided in accordance with embodiments of the invention implements a flexible approach to the processing and routing of raw instrument data between plug-ins and conversion of raw data into measurement data and for post-processing of the measurement data for logging, alarm processing or display purposes.

In this manner, additional devices can be brought into operation in the system without having to shutdown or manually reconfigure the system to accommodate operation of the new instruments.

  • some plug-ins may perform protocol conversion and if data packets contain several "layers" or different portions of data encoded in different protocols, and each plug-in can perform conversion of data related to its specific protocol.
  • the data collection plug-in 150 may perform no conversion of the raw data 192 into measurement data 194 but may simply operate to collect raw data from an instrument (and possibly receive commands from the data engine core as raw data to be forwarded to the instrument, according to the protocol specified by that plug-in). In such cases, conversion of raw data to measurement data is left up to the route manager 132 to route the data to one or more dedicated data conversion plug-ins 150 that operate in conjunction with each other, such as in a sequence, to perform the conversion of the collected raw data 192 to measurement data 194.

Thus routing is performed in this example based on data type, as well as plug-in identity.
  • Still other configurations can provide selective routing in which raw data can be segmented into portions that are routed to the same or to different destination plug-ins based on the content of the data itself.
