LEARN ABOUT THE BMS SYSTEM

BMS is a real-time, online, multimedia, multi-user synchronized system. It is a microprocessor-based system that includes central microprocessors with all associated software and hardware, input and output devices, area microprocessors, sensors, and is controlled through point matrices.

Structure of the BMS System

1. Execution Level

The execution level includes inputs such as sensors, cameras, card readers, etc., and outputs like actuators such as fans, air conditioners, lights, alarms, bells, speakers, pumps, valves, motors, etc. Its main function is measurement, actuation, and signal conversion when necessary. In practice, most sensor or actuator devices have their own control systems to ensure accurate and responsive measurements/actuations. Smart devices (with their own microprocessors) can also handle processing and preparing information before it is sent to higher-level controllers.

2. Control Level

The control level typically involves controllers such as DDC, PLC, PXC, PAC, etc. The primary task of the control level is to receive information from sensors, process that information according to a specific algorithm, and transmit the results to the actuators. Computers monitor the measuring tools and perform tasks like opening/closing valves, adjusting levers, turning knobs, etc. The key feature of the control level is information processing. The control and execution levels are often collectively referred to as the Field Level because controllers, sensors, and actuators are installed directly in the field near the technical systems.

3. Supervisory Control Level

This level is responsible for monitoring and operating technical processes, assisting users in application installation, operation monitoring, and handling abnormal situations. In some cases, this level also performs advanced control tasks such as coordinated control, sequential control, and formula-based control. Performing functions at the control and supervisory levels typically does not require special hardware; normal computers are sufficient.

4. Management Level

What does the BMS system manage?

The Building Management System (BMS) controls and monitors the following systems:

• Power distribution station
• Energy metering system: BTU Meter
• Backup generators
• Lighting system
• HVAC (Heating, Ventilation, and Air Conditioning) system
• Fire alarm system
• Fire suppression system
• Elevator system
• Public information system (audio, screens, etc.)
• Access control system (ACS)
• Security system
• Car parking system

Features of the BMS system:

• Allows building utilities (smart devices) to operate in synchronization and accuracy as required by the operator.
• Enables control of building applications through control cables and network protocols.
• Connects technical systems like security and fire alarms via open interface ports with international standard interface languages.
• Monitors air quality and the working environment for people.
• Collects and reports information.
• Provides fault alerts and timely warning signals before issues occur.
• Manages data, including program creation, database management, graphic program editing, data storage, and backup.
• The BMS system is flexible and scalable, ready to meet all requirements with future solutions.

Benefits of the BMS system:

• Simplifies and automates repetitive procedures and functions.
• Better management of equipment throughout the building via data storage systems, maintenance programs, and automated alert reporting systems.
• Reduces incidents and provides quick responses to customer requests or emergencies.
• Reduces energy costs through centralized control and energy management.
• Reduces labor costs and training time – easy-to-understand usage, with a visual management model displayed on the computer, minimizing personnel and training costs.
• Easily upgradeable and flexible in programming according to needs, size, organization, and various expansion requirements.

Applications of the BMS system:

With the benefits that the BMS system brings, it is widely applied in:

• Office buildings, shopping centers, banks, insurance companies.
• Public administrative buildings.
• Pharmaceutical buildings, hospitals.
• Train stations, subways.
• Hotels, restaurants, cafeterias.
• Universities, high schools.
• Call centers, entertainment centers, television stations.
• Power plants.
• Airports, information centers…
