The BMS system structure in the factory

The BMS system structure in the factory

The BMS system structure in the factory plays an extremely important role in managing and controlling the factory’s technical systems. BMS is an intelligent automation system that integrates many devices and sensors to monitor and adjust environmental factors throughout the factory.

Introduction to the structure of the BMS system structure in the factory

Concept of BMS system structure (Building Management System)

Building Management System (BMS) system structure refers to the way hardware and software components are organized and arranged in the BMS system to ensure effective operation and synchronous integration between subsystems. The BMS system structure includes the following main components:

  • Central control layer: This is the main control center of the BMS system, including server and management software.
  • Regional controller layer: Regional controllers manage and control subsystems in each specific area in the factory.
  • End device layer: Includes terminal devices such as sensors, actuators, control devices, etc. connected to the area control layer.
  • Communication network: Network infrastructure connecting different components in the BMS system.

The importance of BMS system structure in industrial factory management

BMS system structure plays an important role in the effective management of mechanical and electrical systems and infrastructure in industrial factories. A suitable BMS system structure brings the following benefits:

  • Integrate and coordinate the operations of different subsystems synchronously and effectively.
  • Provides centralized monitoring and control, making management easier.
  • Ensure future scalability and flexibility as needs change.
  • Improve system security and safety by controlling access and decentralizing permissions.
  • Optimize operating performance and save operating costs thanks to strict management and control.

Factors affecting the BMS system structure in the factory

  • Factory size and layout: Size, number of buildings, and division of production and office areas affect how the area control layers are organized.
  • Type of production and technology used: Control, monitoring, and automation requirements vary depending on the type of production and technology used.
  • Existing electromechanical systems: The BMS system structure must integrate and effectively manage the existing electromechanical systems in the factory.
  • Future expansion and development needs: The BMS system structure needs to be flexible enough to expand and integrate new systems in the future.
  • Performance, security, and safety requirements: BMS system architecture must meet strict performance, security, and safety requirements in industrial plant environments.
  • Budget and implementation costs: BMS system implementation budget and costs are also an important factor affecting the selected system structure.

Therefore, considering and considering all these factors is very important to design and implement a suitable and effective BMS system structure for an industrial plant.

The main components of the BMS system structure in the factory

Hardware of the BMS system structure

  • Central server: This is the server that stores and processes data for the entire BMS system.
  • Workstation: Allows users to access, monitor, and control the BMS system.
  • Central Controller: Manages and controls subsystems in the factory.
  • Field Controller: Monitors devices and systems in a specific area.
  • End Devices: Includes sensors, actuators, control devices, etc
  • Data Storage System: Stores operational and historical data of the BMS system.
  • Network System: Network infrastructure connects hardware components in the BMS system.

Software of the BMS system structure

  • BMS management software: Main software to monitor, control, and manage the entire BMS system.
  • Energy management software: Monitor, analyze, and optimize energy consumption in the factory.
  • Device management software: Monitor and control terminal devices in the BMS system.
  • Programming and control software: Allows programming of control logic and automation
  • Reporting and data analysis software: Create reports and analyze operational data of the BMS system.
  • Security and access control software: Ensure security and access control to the BMS system.

Communication protocol of BMS system structure in the factory

  • Network Protocols: such as Ethernet, TCP/IP, BACnet, LonWorks, Modbus, etc. Used to connect hardware components in the BMS system.
  • Control Protocols: such as BACnet, LonWorks, Modbus, KNX, etc. Used to transmit control signals and data between terminals and controllers.
  • Application programming interfaces (APIs): Enables integration and communication. With external systems or third-party applications.

These components work together to create a full BMS system structure. Allows effective monitoring, control, and management of electromechanical systems. Or infrastructure in industrial factories.

Network architecture and connection in the BMS system structure in the factory

Network architecture of BMS system structure

  • High-level Network: This is the main network connecting the central server. And workstation and central controller. This network typically uses Ethernet and TCP/IP protocols to ensure high speed and reliability.
  • Subnet: Each area or building in the factory has a subnet. Connect the zone controllers and terminals in that zone. Sub-hierarchical networks can use protocols such as BACnet, LonWorks, or Modbus. To transmit control signals and data.
  • Direct Access Network: Terminal devices such as sensors and actuators. Connected directly to the area controller. Through this direct access network, appropriate control protocols.

This network architecture allows for decentralization and distribution of network load. At the same time, ensuring flexibility and scalability in the future.
