How a Building Control System Works

 

A building automation system (BAS) encompasses a diversity of components consisting of process monitoring and controls. These constitute a complex matrix that makes operational monitoring and control of various activities within a building possible. The use of intricate technologically developed features makes the posses both easy to monitor and correct in real-time. In case you’re unsure or you have no idea at all how a building control system works, here’s a brief view of its working methodology.

Sensor nodes

The primary source of the information in a BAS system is a series of sensor nodes. These are strategically located in areas of interest. In a classic scenario, such sensors might involve sensory devices for detecting carbon dioxide levels in a building or light intensity sensors. These components allow for the collection of first-hand information about the building on cover.

Control unit

These are typically the “brain systems” of the building control system. They are conceptually assumed to be the brainy part of the system as they decide on the data to be collected and define how the system should respond when a given piece of information is fed into the system. All information collected from various parts (input or output) goes to the logic control unit for processing.

Communication protocols

In its ideal expression, the communication protocol in a BAS system is a machine language that one component uses to pass a given message to another. A commonly used protocol in most BAS system is the BACnet. All first-hand information collected from the sensors is coded into a communication protocol the components in the system will understand for action.

Dashboard

This is the interface through which users of the system engages the system. It is also here that the data captured from various sensors is reported in preparation for storage.

Output devices

User commands are often executed through interactive output presentation from a BAS system. The human understandable output is often presented through a combination of output devices such as actuators, monitors and relays.
