Mobile Commissioning of Building Automation Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning of regulation and control devices in building automation, such as HVAC systems, is often inadequately documented, leading to incomplete and time-consuming troubleshooting processes due to insufficient test documentation and lack of transparency in project progress tracking.
Innovation Solution
A method involving a communication connection between the regulation and control device and a mobile communication terminal, where data points representing the status of field devices are queried, checked, and transmitted to a central location, utilizing mobile devices with installed software to facilitate efficient and complete documentation, including GPS or indoor positioning for locating devices and multimedia features for error reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If commissioning is documented manually with commissioning tools or paper data point lists, then the commissioning process can be completed, but the documentation is time-consuming and often incomplete
Solution Approach 1:
The patent replaces manual documentation methods (paper-based or tool-based commissioning processes) with an automated mobile device-based system. The mobile device automatically queries data points, captures status information, and transmits documentation to a central location, eliminating the need for manual writing and reducing documentation time while improving completeness.
Solution Approach 2:
The commissioning device performs self-documentation by automatically querying its own data points and status information. The system captures and transmits commissioning data autonomously without requiring manual intervention for data entry, thereby reducing documentation time and ensuring complete recording of all commissioning parameters.
2Productivity
If commissioning is documented individually and manually by commissioning technicians, then documentation can be created, but the process is time-consuming and often incomplete
Solution Approach 1:
The patent replaces the manual commissioning documentation process with an automated mobile device system that queries data points, captures status information, and transmits documentation automatically. This substitution eliminates the time-consuming manual documentation process while improving commissioning productivity through automated data capture and transmission.
Solution Approach 2:
The mobile device enables continuous commissioning work by automatically documenting data points as they are queried, without interruption for manual writing. The system maintains continuous operation by seamlessly capturing and transmitting commissioning data in real-time, thereby improving productivity and reducing documentation time.
3Ease of operation
If regulation and control devices are installed in hard-to-locate positions (false ceiling, under window panels, in false floor), then space utilization is optimized, but it becomes difficult for commissioning engineers to find and localize the devices
Solution Approach 1:
The patent introduces a mobile device as an intermediary tool that bridges the gap between commissioning engineers and hard-to-locate control devices. The mobile device provides navigation assistance and information access, enabling engineers to quickly locate and work with control devices installed in difficult positions without excessive searching time.
4Ease of repair
If troubleshooting is performed without sufficient test documentation, then the process can proceed, but troubleshooting becomes time-consuming due to incomplete information
Solution Approach 1:
The patent implements preliminary documentation of all commissioning data, including test results and status information, before troubleshooting is needed. By automatically capturing and storing complete commissioning documentation during the initial setup phase, the system ensures that all necessary information is readily available when troubleshooting occurs, thereby reducing troubleshooting time and improving efficiency.
