Building Equipment Schedule Synchronization With Secure Diagnostics
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 securing diagnostic data, leading to inefficiencies and potential security risks.
Innovation Solution
A BMS that includes a system manager capable of discovering and synchronizing schedules across equipment, detecting malfunctions through a malfunction detector and diagnostic file creator, and encrypting diagnostic data for secure access, allowing for centralized management and security of building equipment operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a BMS manages schedules across multiple building sites, then operational coordination improves, but system complexity increases
Solution Approach 1:
The system segments schedule management by creating site-specific schedule objects that can be independently managed and synchronized. Each building site has its own schedule setpoints that can be discovered, modified, and synchronized separately, reducing the complexity of managing multiple sites as a single monolithic system.
Solution Approach 2:
The system provides universal schedule management capabilities that work across multiple building sites through a common interface. The schedule manager can discover, modify, and synchronize schedules across different sites using the same mechanisms, eliminating the need for site-specific customizations and reducing overall system complexity.
2Productivity
If the system discovers and synchronizes schedules across equipment, then schedule management efficiency improves, but data security risks increase
Solution Approach 1:
The system introduces an encrypted code generator as an intermediary between the schedule manager and external systems. This intermediary component secures diagnostic data and schedule information by encrypting it before transmission or storage, allowing efficient schedule synchronization while mitigating data security risks through cryptographic protection.
3Reliability
If malfunction detection and diagnostic file creation are implemented, then equipment reliability improves, but system complexity increases
Solution Approach 1:
The system merges malfunction detection and diagnostic file creation into an integrated diagnostic subsystem. The malfunction detector works seamlessly with the diagnostic file creator to automatically generate encrypted diagnostic files when equipment malfunctions are detected, improving reliability while reducing complexity by combining these functions into a unified workflow rather than separate independent systems.

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.
