Building Management System (BMS)
The technical basis of smart buildings is the Automated Building Management System & nbsp;
It is designed to automate processes and operations that are implemented in modern buildings. Quite often in the literature there is the use of the term ACSZ, as a system for the automation of engineering systems (or life support systems) of a building: ventilation, heating and air conditioning, water supply and sewerage, power supply and lighting, etc. In large and complex buildings, several dozen can be distinguished engineering systems.
The main goals of creating an automated control system are to improve safety, improve comfort and ensure the efficiency of resource consumption (including through participation in electricity demand management). This is a complex task, often based on a specific (specific to the company using the building) business concept. The result is achieved due to the better quality of the building’s life support systems while reducing the cost of maintenance personnel.
When building an automated control system, as a rule, three levels of automation are implemented:
Upper — the level of dispatching and administration (Management Level) with databases and statistical functions, at which the interaction between personnel (operators, dispatchers, etc.) and the system is carried out through a man-machine interface implemented mainly on the basis of computer tools and SCADA systems. The same level should be responsible for communication with the enterprise level.
Medium — the level of automatic (automated) control (Automation Level) of functional processes, the main components of which are controllers, signal input-output modules and various switching equipment.
Low — Field Level with input / output functions, including sensors and actuators, as well as cable connections between devices and low-middle levels .
