Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building automation systems, particularly HVAC DDC controls, face challenges in combining high-power event handling with real-time capabilities and lack robust cybersecurity, leading to inefficiencies and energy waste due to inadequate control and monitoring.
Innovation Solution
A scalable and secure direct digital control platform integrating HVAC DDC control with an embedded workstation platform, utilizing a Niagara-based controller with advanced cybersecurity features like SSL encryption and a Java application control engine for unified connectivity and predictive maintenance, along with a pseudo-deterministic function block engine for efficient real-time performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an embedded workstation platform with event-driven approach (Windows OS or Unix OS) is used, then high-power event handling capability is improved, but real-time performance deteriorates
Solution Approach 1:
The system is divided into two separate controllers: a workstation platform controller handling high-power events and applications, and a real-time controller handling time-critical HVAC control functions. This segmentation allows each controller to specialize in its strength without compromise.
Solution Approach 2:
A communication interface acts as an intermediary between the workstation platform and real-time controller, enabling coordinated operation where the workstation can initiate high-power events while the real-time controller ensures timely execution and monitoring.
2Reliability
If traditional building automation systems are used, then system simplicity is maintained, but cybersecurity robustness deteriorates
Solution Approach 1:
The system merges traditional HVAC control functionality with modern cybersecurity features and workstation capabilities into an integrated platform, achieving enhanced security without requiring completely separate systems.
Solution Approach 2:
The controller is designed as a multi-functional device that simultaneously provides real-time HVAC control, high-power event handling, cybersecurity protection, and communication interfaces, reducing the need for multiple separate components.
3Productivity
If separate controller and supervisor systems are used, then functional independence is maintained, but system integration efficiency deteriorates
Solution Approach 1:
The controller integrates both control and supervision functions into a single unified system, eliminating the need for separate supervisor hardware while maintaining all necessary monitoring and control capabilities through integrated software modules.

AI summary
A powerful direct digital control (DDC) and integration control platform that is scalable and easy to use and meet building owners and contractors' desires for a highly secure and robust technical solution. One may combine heating, ventilation and air conditioning (HVAC) DDC control with the embedded workstation platform, and DDC controllers with embedded workstation platform software design. An embedded workstation platform event-driven approach (such as a Windows operating system (OS) or Unix OS environment) is not necessarily easily suited to real-time common in HVAC DDC control. The present system may solve an issue of combining high-power event needs for HVAC DDC Controls.
