Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building management systems (BMS) require extensive time and effort for point and wiring checkout before control logic is defined, delaying the system's online availability.
Innovation Solution
A method and system that allow for intuitive point and wiring checkout of BMS using a mobile device to associate points with I/O terminals, perform tests, and change terminal states without requiring pre-loaded control logic, enabling wireless connection and configuration of BMS controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control logic is required to be defined and available before point and wiring checkout can be performed, then the system ensures complete control logic integration, but the time required to bring the BMS online is significantly increased
Solution Approach 1:
The system performs point and wiring checkout actions before the control logic is fully defined or available. The mobile device enables installers to test I/O terminals, verify wiring connections, and validate device communications during the installation phase, rather than waiting for control logic completion. This preliminary execution of checkout tasks significantly reduces the overall commissioning time while maintaining system reliability.
2Reliability
If traditional wired connection methods are used for BMS controller configuration, then stable communication is achieved, but the complexity and time required for installation increases
Solution Approach 1:
The system replaces traditional mechanical wired connections with wireless communication technology. The mobile device establishes wireless connections with BMS controllers and I/O devices, eliminating the need for physical cable connections during configuration and checkout. This substitution maintains communication reliability while dramatically reducing installation complexity and time, allowing installers to configure and test systems without extensive wiring work.
3Reliability
If control logic must be fully developed before installation checkout, then complete system functionality is ensured, but the installation timeline is extended
Solution Approach 1:
The system segments the BMS commissioning process into independent phases: installation and wiring checkout can be performed separately from control logic development. The mobile device enables the installation phase to be completed and validated independently, allowing parallel progression of installation activities and control logic development. This segmentation eliminates the sequential dependency that previously slowed down installation productivity.
4Reliability
If extensive point and wiring checkout procedures are required before control logic availability, then thorough system validation is achieved, but the time and effort required increases significantly
Solution Approach 1:
The system implements self-service capabilities where the mobile device automatically performs checkout procedures, tests I/O terminals, and validates wiring connections without requiring manual intervention for each test point. The automated testing and validation processes reduce the time and effort required for thorough system validation, while the mobile device handles the complex checkout procedures independently.

AI summary
A mobile device running an application may be used to perform a checkout on a BMS system. The mobile device may be used to obtain configuration information for the BMS system from a remote device, the configuration information including an association of points with particular I/O terminals of BMS controllers of the BMS system. The mobile device may be used install the configuration information on the BMS controllers, and perform a point and wiring checkout of the various BMS controllers before the control logic for the BMS controllers has been fully defined and made available.
