Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing amount of data from smart building environments poses a challenge for effective analysis, as existing building management systems struggle to efficiently manage and process the vast amounts of timeseries data from various objects, devices, and systems, leading to inefficiencies in data management and decision-making.
Innovation Solution
A building management cloud computing system that processes timeseries data by generating input timeseries from raw data points, identifying object and data entities, and creating derived timeseries through processing workflows, while also storing historical values and calculating virtual data points, thereby enhancing data analysis and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If building management systems collect data from multiple objects and systems in smart building environments, then the amount of available data for analysis increases, but the complexity of managing and processing the data increases
Solution Approach 1:
The patent segments the building management system into multiple independent components: building management systems at individual building levels, a building management platform for data collection and processing, and a building management application for analysis and decision-making. This segmentation allows each component to handle specific tasks independently, reducing the overall complexity of managing vast amounts of data from multiple objects and systems.
2Measurement precision
If building management systems process vast amounts of timeseries data from various objects, then the quality of analysis and decision-making improves, but the processing time and computational resources increase
Solution Approach 1:
The building management platform performs preliminary data processing, validation, and standardization before data reaches the analysis stage. Timeseries data from multiple building management systems is pre-processed to ensure consistency and quality, which reduces the computational burden during actual analysis and enables faster decision-making without sacrificing data quality.
3Adaptability or versatility
If building management systems integrate multiple building subsystems and devices, then the versatility of the system improves, but the difficulty of detecting and measuring system performance increases
Solution Approach 1:
The patent implements a universal building management platform that can interface with and process data from diverse building subsystems including HVAC, lighting, security, and access control systems. The platform uses standardized data formats and protocols to handle multiple data types uniformly, making it easy to detect and measure system performance across different subsystems while maintaining high versatility.
