Key Concepts¶
Before diving into EnOS Unified Monitoring, mastering the following key concepts will help you efficiently understand and utilize the feature.
Data Foundation: Sources of Monitoring Content¶
Asset¶
An asset is the core monitoring object, serving as a digital representation of a physical device (such as a wind turbine or inverter) or an abstract entity (such as a virtual power plant). Each asset is created based on a predefined Model and inherits the attributes, measurement points, and metrics defined by that model.
For more information about modeling, see EnOS Model Management.
For more information about asset management, see Device and Asset Management.
Data Types¶
Unified Monitoring processes three main types of data, which together form a comprehensive profile of an asset:
Attribute: Static descriptive information of an asset, such as device ID, model, installation location, or person in charge. Attributes typically do not change frequently.
Measurement Point: Dynamic operating status data generated during asset operation, such as real-time telemetry data including voltage, temperature, and rotational speed.
Metric: Statistical values calculated based on raw measurement points that reflect business performance, such as “daily power generation”, “equipment availability”, and “mean time between failures (MTBF)”.
Domain¶
A domain is a collection of assets and monitoring requirements within a specific industry or business scenario. For example, the wind domain includes assets such as wind farms and wind turbines along with their associated monitoring scenarios. Unified Monitoring supports cross-domain views, allowing users to view and manage assets from different domains (such as wind power and solar PV) on a single page.
Organizational Logic: How to View Assets Structurally¶
Asset Hierarchy¶
An asset hierarchy is a tree structure that reflects asset management and ownership relationships, usually inherited from the Organization Structure in EnOS Application Portal. A typical hierarchy example is as follows:
Group (Global) -> Region -> Site -> Device
Each node in the organization structure can be associated with specific assets. End users must be granted permission by an OU Administrator to access a specific node before they can view all asset data associated with that node and its child nodes, ensuring data security and isolation.
Asset Aggregation¶
When displaying massive numbers of assets on high-level maps or charts, the aggregation feature summarizes and displays data from multiple assets according to specific rules. For example, aggregating by administrative region on a map combines all solar PV power plants within a province into a single node and displays their total power generation.
Site Groups and Device Groups¶
Site groups and device groups are dynamic asset collections created to meet specific analytical needs, such as “top 10 most efficient wind turbine groups” or “all equipment pending maintenance”. They serve as a flexible supplement to the fixed asset hierarchy and are commonly used in the Charting Tool.
Functional Carriers: How to Build and Use Monitoring Interfaces¶
Canvas, Panel, and Widget¶
Canvases, panels, and widgets are the core elements for building the Portfolio. Their relationships are as follows:
Canvas: The foundational layout area of a page. In Portfolio, multi-level canvases (such as global, region, and site-level canvases) can be configured. Each canvas hosts visualization content designed for a specific asset level, enabling seamless drill-down navigation from a macro to a micro perspective.
Panel: An independent functional area on a canvas, typically located on the left or right side of the canvas, containing a group of related information or controls.
Widget: Specific visual charts or elements placed within a panel, such as ranking lists, time-series charts, and action buttons. Widgets are categorized into:
Standard Widgets: General-purpose widgets without built-in asset information, suitable for most scenarios, requiring manual configuration of data items.
Special Widgets: Widgets designed for specialized scenarios that include specific data items. They come with built-in data logic while also supporting additional data items.
Metric Inquiry Report¶
A Metric Inquiry Report is a standardized, tabular report generated through the Common KPI Inquiry feature. It displays detailed or aggregated attribute, measurement point, and metric data for a set of assets within a specified time period, making it suitable for periodic reporting and bulk data analysis.
Asset Data Chart¶
An Asset Data Chart is a data visualization chart (such as trend lines) generated through the Charting Tool. It focuses on revealing data fluctuation patterns of a single asset or a group of assets over time, used for in-depth analysis and fault diagnosis.
Configuration and Control: How to Customize and Integrate¶
Non-Connection Status¶
Non-connection is an asset status defined by application developers in the Asset List to indicate that an asset has lost its data connection to the EnOS cloud. Application developers can choose to mark data for such assets as invalid (excluded from calculations) or display it normally (included in calculations), helping users distinguish data reliability.
Template¶
A template is a preset query or analysis scheme containing a predefined asset scope, data items, time range, and more. When using the Charting Tool or Common KPI Inquiry, end users can directly apply templates to quickly initiate a standardized analysis, boosting efficiency.
URL Parameter¶
URL parameters are key-value pairs appended to the URLs of various Unified Monitoring feature pages. They are used to precisely control the initial state of a page when opened, such as the default selected asset, time range, or chart type. This is a key mechanism for page-level integration into custom applications, enabling deep link sharing and direct contextual access.
