Embedded Computing offers a comprehensive look into the complexities of building automation systems in the age of the Internet of Things (IoT).
The piece tracks through the layers of building elements. It defines building automation systems and building automation device networks. The piece points out that BAS device networks have primary and secondary busses. These connect to BMS nodes, including BMS units, zone controllers and end nodes. Both busses may connect to low-level controllers, I/O devices and end user applications such as thermostats and alarm monitoring systems. These systems can be wired or wireless.
Wired networking protocols include BACnet, LonMark and Modbus. Installing new, wireless systems, the story says, can be difficult in older buildings. Wireless connectivity options include Bluetooth Low Energy (BLE), WiFi and various sub-1 GHz approaches.
The bottom line is that is that automating energy and other functions in a building is very complicated and a bit intimidating. That complexity will grow as two elements – wireless technology and the IoT – proliferate. The networks will link in more equipment, including those specific to an industry. In addition, existing networks each will produce more data.
Efforts are underway to simplify this dilemma, which could undermine the great potential of the new approaches:
BAS developers continue to explore a scalable, cost-competitive solution that supports standardized open communication protocols. Wired and wireless protocols are now integrated into every facet of building control systems. TI’s SimpleLink MCU platform offers a broad portfolio of wired and wireless MCUs which are highly integrated, low-power solutions that enable developers to quickly add connectivity protocols to end nodes in BCS systems. With common software across all of the SimpleLink MCUs, code is reusable from application to application, making it easy to add functionality to new or existing applications.
