Remote Load Control Messaging via Broker-Based Subscription Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for communicating with and controlling load control systems, such as lighting, HVAC, and window treatments, across multiple environments, especially in a unified and scalable manner.
Innovation Solution
A system is configured to maintain a database associating identifiers with load control systems, allowing for message communication and control through a network device, utilizing message brokers and HTTP interfaces to manage subscriptions and message forwarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized database system is implemented to manage multiple load control systems, then scalability and user accessibility are enhanced, but device complexity and integration requirements increase
Solution Approach 1:
The message broker system serves multiple functions: it acts as a communication intermediary between network devices and load control systems, maintains subscription mappings in a database, routes messages based on identifiers, and enables both publishing and subscribing operations. This multi-functional approach allows a single centralized system to handle diverse communication requirements across multiple environments, enhancing scalability while managing complexity through role consolidation.
2Ease of operation
If message brokers and HTTP interfaces are used to manage subscriptions and message forwarding, then communication efficiency and remote management capability improve, but device complexity and integration requirements increase
Solution Approach 1:
The message broker acts as an intermediary component that simplifies remote management operations. It receives subscription requests from network devices via HTTP interfaces, stores mapping information in a database, and automatically routes messages between publishers and subscribers. This intermediary approach enables remote management capability by allowing network devices to interact with load control systems through standardized interfaces without requiring direct integration complexity at each endpoint.
3Measurement precision
If identifiers are associated with load control systems in a database for message routing, then message delivery accuracy improves, but information processing requirements and system complexity increase
Solution Approach 1:
The system uses identifier copying and mapping where each load control system is assigned a unique identifier that is stored in the database as a mapping key. Instead of processing complex device addresses or configuration data, the system copies and routes messages using these simplified identifier references. This approach maintains high message routing accuracy while reducing information processing overhead by replacing detailed device information with compact identifier representations.
