DESCRIPTION

The present system and approach may incorporate one or more processors, computers, controllers, user interfaces, wireless and/or wire connections, and/or the like, in an implementation described and/or shown herein.

This description may provide one or more illustrative and specific examples or ways of implementing the present system and approach. There may be numerous other examples or ways of implementing the system and approach.

The Novar™ Opus™ supervisor may provide the system and approach that is being disclosed herein. A user of the Novar Opus supervisor may manage and communicate with hundreds or thousands of remote site controllers from a centralized location via the users' intranet. These site controllers may be referred to as an XCM controller or XCM. The XCM in turn may manage and communicate with tens or hundreds of field controllers within the site that performs real time control of building equipment such as HVAC units, lighting panels, metering and refrigeration circuits.

The Opus supervisor may be a single instance application designed to support all the supervisory functions needed by an Opus building automation system (BAS). The terms “application” and “app” may be used interchangeably herein. A supervisor application may typically be serving upwards of thirty plus simultaneous user client connections requesting data and invoking of numerous multi-site operations. The functions available to the users may incorporate site monitoring, configuration and version management, batch setpoint and schedule updates and data report generation. Also, the same supervisor may be responsible to collect runtime alarms, historical trend data, site backups and configuration data from all sites into centralized databases.

An issue that Novar may have experienced is that the single process Opus Supervisor application does not appear to perform adequately or reliably when burdened with all the work associated with supporting thousands of deployed sites of XCM controllers. For example, each site XCM may be typically configured with 600 plus historical trend logs. A customer with 2000 sites may expect to be collecting two to three Gigabytes of historical data each day, depending on recording intervals. The supervisor application may also be collecting thousands of alarms from the 2000 sites throughout a day. Additionally, users may be connected to the supervisor performing individual site downloads, site backups or batch updates across all sites. The users also may be running multi-site reports of historical data or configuration exception reports. All of these operations running simultaneously appear to have shown experientially to be too much for a single supervisor application. An experience with a Novar customer of 2000 sites may have unveiled the architectural deficiency of an existing single process Opus supervisor application. In supporting the customer, one may need to monitor the operation of the Opus supervisor very closely to maintain its operation. The supervisor application may be found to be using significant system memory and CPU consumption resulting in an extremely unstable application. In the future, there may be additional customers that will require the supervisor to support up to nearly 25,000 site XCM's. The only approach to solving this with the current offering appears to be installing and configuring multiple Opus supervisors each with a smaller fixed number of supported sites. However, this solution may be unacceptable to the customer as each instance is independent and could require the user to perform significantly more workflow actions to navigate to more than one supervisor to perform the required operations.

The present system and approach may provide a solution to the issue by providing the following product features and the necessary user activities required to use these features. A new product may be provided labeled as an Opus data manager. The product may be a focus of the present system. Architectural goals of the Opus data manager may be simply to distribute the workload of the existing Opus supervisor across multiple processing units while at the same time maintaining a seamless and integrated workflow for the user experience. As customer enterprises grow with the addition of more sites, additional Opus data managers may be added to support the growth. An existing feature set of the single instance Opus supervisor may continue to operate as it is not necessarily requiring the user to knowingly make use of the distributed processing units. The Opus data manager framework may provide distributed processing for select Opus supervisor application features. For example, the Opus supervisor feature that imports historical trend data from virtually all the remote sites into relation databases may heavily burden the single Opus supervisor application. For a customer having 2000 sites, two instances of an Opus data manager history application may each support 1000 sites. Initially, the Opus data manager may provide distributed application support for history data collection, alarm collection and meter data management. Additional feature based applications may be also available for distribution. Once the distributed applications are running, the Opus supervisor may automatically distribute the configuration (work) to be performed to the available application. The Opus data manager and associated applications may maintain a runtime capacity percentage that can be used by the Opus supervisor when distributing the work load. This may allow the Opus supervisor to continue to scale by identifying the optimal processing unit to handle the distributed work. A feature for the distributed application may be that the work can be performed independently and autonomously where resulting data updates are integrated back to the main Opus supervisor. This approach may be accomplished by using Niagara™ communications and services, files or databases.

To summarize, the Opus data manager product may enable the Novar Opus BMS system to more easily scale to support the anticipated growth of the customer enterprises. The following items considered as features may incorporate a distributed processing framework providing a path for future scale improvements, maintained single user workflow experience with multi-application integration, and automatic capacity balancing.

A significant difference of the present approach is that the Opus data manager framework may solve the issue of scalability by allowing the addition of new instances of applications and new application types as scaling improvements are incrementally introduced.

An Opus data manager may be an installation of a Niagara environment that will provide an Opus data manager station and a library of predefined set of Opus application templates (stations) available to run within that environment. An Opus data manager may be a framework that can run one or more applications, depending on the available host server resources. A built-in Opus data manager station may be primarily responsible for an integration with the Opus supervisor. The initial application templates available may be for alarm collection, history collection and meter data collection. New application templates may be available to distribute work for site backups, and report data collection and batch execution. After an Opus data manager is installed on an independent host server, it may be joined to the main Opus supervisor. This integration may allow for a seamless workflow for the existing Opus supervisor activities. The BMS engineer may instantiate the required application instances needed to offload the Opus supervisor. Once the applications are created, the user may configure any application setup required as an initial, one time activity. After this is complete, the distributed application may be running and integrated with the Opus supervisor. The BMS programmer may perform an existing activity to join a new site XCM to the Opus supervisor. A new “XCM join” process may detect an existence of the Opus data manager and associated applications. The XCM join process may automatically add the XCM specific configuration required to the distributed application. Another aspect of the XCM join may be to support multiple instances of a particular application template type. For example, if the XCM join is distributing work to a history application, the “join” may query the Opus data managers for the capacity of each of the existing history applications. Based on the resulting available capacities, the join process may find a distributed application best suited with the most available capacity to be assigned the work. Also, if during the XCM join process a distributed application is not necessarily found, the XCM may be configured (joined) into the main Opus supervisor.

An Opus multi-supervisor may simply maintain existing supervisory functionality but allow for application features and work to be distributed across multiple processing units as sites are being added to the system. The views may convey how each function can be distributed. An element to accomplish the Opus multi-supervisor may be the Opus data manager.

An Opus data manager may be an installation of a Niagara environment that can provide a predefined set of Opus application templates (stations) available to run within that environment. An Opus data manager may be a framework that can run one or more applications, depending on the available host server resources. The initial application templates available may be for alarm collection, history collection and meter data collection. New application templates may be made available to distribute work for site backups, and report data collection and batch execution.

An Opus meter manager app may collect meter data from multiple sites and send the data to a utility. An Opus history app may collect historical time series and event data provided to an Opus structured query language (SQL) database. An Opus alarm app may collect alarm and event data provided to an Opus SQL database.

An Opus data manager may be indicated in a diagram of FIG. 1. Each application instance may support a limited number of deployed site XCM controllers or meters. As the number sites increases beyond the limit that an application can support, the user may be advised to add additional applications or Opus data managers to support the continued growth.

An Opus multi-supervisor structure may consist of existing elements of a current single Opus supervisor architecture. This may include the Opus architect client (workbench), the Opus supervisor station, one or more Opus data managers and one or more application stations.

An Opus multi supervisor structure may be revealed in a diagram of FIG. 2. The Opus data manager may exist as an additional element of the existing Opus supervisor structure. An overall Opus multi supervisor environment may consist of multiple Opus architect clients, a single Opus supervisor and one or more Opus data managers. Within an Opus data manager, there may be one or more Opus applications used to distribute work from the Opus supervisor.

The Opus architect (workbench) may be available within the Opus data manager installation environment for local host configuration of the Opus data manager. When connected, the Opus data manager platform may be accessed as well as the Opus data manager station and all running application stations. Alternately, when the Opus architect is connected to the Opus supervisor, the user may navigate to any instance of the Opus data manager.

The Opus supervisor may provide a new Opus data manager service. The service may support the seamless integration of Opus data managers and associated applications. An example of the integration may be to ensure that when the user invokes an existing XCM join feature, the supervisor can ensure that the new site XCM is also configured in a distributed application. The example may be accomplished by the Opus data manager service and with access to the Opus data manager stations within the Opus supervisor Niagara network.

Finally, the Opus data manager element may be a full NiagaraAX™ environment inclusive of the Opus data manager station and a library of available Opus application templates. Upon installation, the Opus data manager station may be joined to the Opus supervisor. This act may allow for a seamless integration of any and virtually all applications added to the Opus data manager. Once available, a BMS engineer may instantiate one or more Opus applications from the application library. The running applications may now be accessible to the Opus supervisor for distributing work.

An Opus data manager with integrated supervisor access may be revealed in a diagram of FIG. 3. A key architectural goal may be for the Opus data manager and associated applications to be seamlessly integrated with the Opus supervisor. The Opus data manager may be accessed via the Opus supervisor and Opus architect client remotely not necessarily needing the user to be logged into on a local server host of the Opus data manager. The activity flow may depict how a BMS engineer user can navigate to and manage the distributed Opus data managers. The activities may usually be performed one time for setup and not necessarily be needed by the daily users.

An Opus “XCM join” to an Opus data manager app may be noted in a diagram of FIG. 4. A workflow to establish a newly deployed Opus XCM into the Opus supervisor may make use of the Niagara join feature. The feature may automate numerous manual configurations to ensure ease of use and consistency when joining the XCM. To support the existence of Opus data managers, the XCM join may follow the activity flow as seen in FIG. 4.
