Comparative Trend View for Building Automation Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building automation systems lack an efficient method for users to quickly and easily analyze comparative trends in data from dispersed devices, hindering effective monitoring and control of building operations.
Innovation Solution
A system manager application in a data processing system generates and displays a comparative trend view on a graphical user interface, allowing users to select a predefined button to offset a first trend view chart by a time period, automatically populating a second chart with trend data values from a database, enabling easy comparison of data over different time ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional trend view display methods are used, then data from building automation devices can be monitored, but users cannot quickly and easily analyze comparative trends in data over different time periods
Solution Approach 1:
The patent combines multiple trend views (current trend and historical trend) into a single comparative display interface. The system merges the first trend view showing current data with a second trend view showing historical data offset by a selected time period, allowing users to analyze comparative trends simultaneously without switching between separate displays or manually configuring multiple views.
Solution Approach 2:
The system performs preliminary actions by automatically generating and offsetting the second trend view based on the first trend view definition. When a user selects a time period, the system pre-configures the comparative trend view with the appropriate time offset and populates it with historical data from the database, eliminating the need for users to manually set up each comparison view.
2Measurement precision
If manual configuration of multiple trend views is required, then detailed data analysis is possible, but the complexity of the interface and operations increases
Solution Approach 1:
The patent implements a universal interface where a single comparative trend view button triggers the generation of multiple offset trend views based on the same underlying definition. This multi-functional approach allows the system to handle various time period comparisons (hour, day, week, month) through a unified mechanism, reducing interface complexity while maintaining detailed data analysis capabilities.
Solution Approach 2:
The system creates copies of the first trend view definition to generate the second trend view with time offset. Instead of requiring users to manually configure each trend view from scratch, the system copies the existing trend view parameters and applies a time offset transformation, simplifying the interface while preserving detailed analysis capabilities through the copied and modified view definitions.
3Measurement precision
If trend data from multiple time periods is displayed separately, then data accuracy is maintained, but the efficiency of data presentation and comparison decreases
Solution Approach 1:
The patent adds a time offset dimension to the traditional single trend view display. By displaying multiple trend views simultaneously with different time offsets (current, historical, and comparative) on the same interface, the system maintains data accuracy for each time period while dramatically improving comparison efficiency through spatial arrangement and visual correlation of the different time perspectives.
