Smart Buildings

MQTT (Message Queuing Telemetry Transport) is an ISO Standard Network Protocol particularly suited to smart technology and the underlying need to efficiently exchange vast amounts of dynamic building-wide status information, to achieve enhanced building performance and utilisation.

SIMMTRONIC’S POWERFUL AND PROVEN MQTT SOLUTION COMPRISES:
• Comprehensive Data Analysis
• Simmtronic Data Aggregation Architecture which enables rapid data provision
• Hosted on Robust Simmtronic SPC.2000 Control Processor with continuous operation
• Simmtronic MQTT Software Model publishes data directly without third party gateways

COMPREHENSIVE ANALYSIS DATA, AVAILABLE INSTANTANEOUSLY, INCLUDING:
• Lighting Levels
• Occupancy Status
• Energy Performance (when purchased with Simmtronic energy monitoring toolset)
• Device specific data for Area Controllers, Light and Blind Control Modules, Sensors
• Gear and Lamp Faults, Maintenance reporting

MQTT DATA FLOWS
The MQTT Architecture consists of three entities: brokers, publishers and subscribers. The broker is an intermediary between publishers and subscribers. Publishers, such as the lighting control system, publish data to the broker about all the assets in their datasets. The broker retains the latest data published for every asset; publishers need to send data for an asset only when the data changes.

AGGREGATION STRUCTURE OF THE SIMMTRONIC LIGHTING CONTROL SYSTEM
The data structure of the Simmtronic lighting control system is tailored to providing rapid MQTT data updates for every lighting asset. Every Lighting Control Module continually collects data from every asset (sensors, light fittings) that it manages. Every Lighting Control Module continually sends the latest data to its Area Controller. Every Area Controller continually sends all this data to the SPC.2000. The Simmtronic IP Parallel Access architecture allows every Area Controller to send data to the SPC.2000 simultaneously.

QR CODES
Labels will be provided where required for fixing to lighting devices. QR codes for all lighting devices will be available at the lighting Head End.

In a smart building, all assets are assigned unique IDs. Large assets may have these IDs fixed to them in the form of labels with QR codes. This allows a maintenance technician to capture the ID onto a smart phone or other device, to allow replacement parts to be ordered. QR code capture ensures that the information is captured and forwarded without risk of typing errors.

MQTT allows a very flexible and scalable way to approach building applications. The Simmtronic MQTT Publisher is set out to gather data from the beginning continuously, it already has the answer.
