Building Equipment Schedule Synchronization Across Multiple Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building management systems (BMS) face challenges in synchronizing and managing schedules across multiple building sites efficiently, detecting equipment malfunctions, and providing secure diagnostic data access.
Innovation Solution
A BMS with a system manager that includes a schedule manager for synchronizing equipment schedules, a malfunction detector for creating diagnostic files, and an encrypted code generator for secure data access, allowing for centralized control and monitoring of building equipment across multiple sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a BMS manages schedules across multiple building sites, then operational control is improved, but system complexity increases
Solution Approach 1:
The system divides schedule management into site-specific schedule objects that can be independently created, modified, and synchronized. Each building site has its own schedule objects that can be managed separately yet synchronized centrally through the enterprise connection, reducing overall system complexity while maintaining multi-site capability.
Solution Approach 2:
The enterprise connection serves as an intermediary layer between the local BMS and remote building sites. It handles schedule synchronization, data transmission, and coordination, allowing the local BMS to manage multiple sites without directly increasing its own complexity. The enterprise connection absorbs the complexity of multi-site management.
2Reliability
If diagnostic data is made accessible for equipment monitoring, then system reliability is improved, but data security risks increase
Solution Approach 1:
The enterprise connection acts as a secure intermediary that mediates access to diagnostic data. It implements authentication, authorization, and encrypted transmission between the BMS and enterprise systems, allowing diagnostic data to be accessed for monitoring while maintaining security controls and preventing unauthorized access.
3Adaptability or versatility
If new equipment is automatically discovered and integrated, then system adaptability is improved, but risk of integrating malfunctioning equipment increases
Solution Approach 1:
The system performs preliminary discovery and integration of new equipment before full operational integration. When new equipment is detected on the system bus, the BMS automatically discovers it, creates corresponding objects, and integrates it into the management system in advance, allowing for verification and configuration before the equipment begins operational schedules.
Solution Approach 2:
The system continuously monitors equipment status and provides feedback through the enterprise connection. Diagnostic data from equipment is collected and analyzed, allowing the system to detect malfunctions and adjust schedules or alert operators, ensuring that integrated equipment operates reliably.

AI summary
A building management system includes building equipment operable to affect a physical state of a building. The building management system includes a system manager coupled to the building equipment via a system bus, the system manager comprising a schedule manager configured to control an operation schedule of the building equipment. A client device is configured to communicate with the schedule manager to modify operation schedules of the building equipment or add new operation schedules for the building equipment. The schedule manager comprises a list of available schedules for the building equipment and is configured to, in response to modification of the operation schedules or addition of new operation schedules, update the list of available schedules to include the modification or the new operation schedule. The enterprise batch synchronization module is configured to create, copy, modify and apply schedule and setpoint configuration templates to multiple cloud connected building equipment simultaneously.
