For sensors, actuators, and controllers to function correctly in a building management system (BMS), a common method of data understanding is vital. Communication protocols describe the rules and formats through which data should be transferred over the interconnected network of sensors, actuators, and controllers. The data captured by sensors gets relayed to controllers that manipulate the system through actuators to the required endpoints. A communication protocol lets multiple device manufacturers make sensors, controllers, and actuators "work” together sharing data so an intelligent, actionable outcome can be achieved.
Smart Building Data Modeling Standards
Data models visually represent the data gathered throughout a connected IT system, either in whole or in part to facilitate its storage with easy access from a database. In built environments, the importance of data modeling comes down to the ability of elements within this system to communicate. To better communicate, common definitions should show from where the data comes and what it represents. To ensure understanding and lessen confusion, rules are used to describe elements within the system.
In smart buildings, devices, software, and building equipment must work together seamlessly. This requires unifying several naming and tagging standards currently used for building automation. While a seemingly simple issue, many data modeling approaches create roadblocks to real-world application of building data. But there is a better way. The Ontology Alignment Project lets you harness the full potential of building data, allows smart solutions to evolve and grow, and supports better performance and efficiency.
Smart buildings are all about communication. At the heart of that communication is a building automation and control system that consists of sensors, controllers, communication infrastructure, and computing resources. Sensors send signals through the communication infrastructure to the computing resources that determine control actions and relay the information back to controllers. Seamless two-way data flow is essential.
