BA190 Edge I/O module enables distributed HVAC control with BACnet/IP integration. Features edge computing, PID optimization, and energy management for enhanced comfort and operational efficiency
Case Details
1. Solution Overview
This solution utilizes the Beilai Technology BA190 BACnet/IP Edge I/O module to provide a distributed control system for building HVAC systems that integrates data acquisition, local intelligent control, and seamless integration. It replaces traditional PLCs or expensive dedicated DDC controllers, pushing intelligent control down to the device level. This enables refined and intelligent regulation of equipment such as fan coil units, fresh air handling units, and pumps, achieving significant energy savings, improved comfort, and reduced operational costs.
2. System Architecture & Working Principle
- Perception Layer: Temperature and humidity sensors, pressure sensors, differential pressure switches, flow switches, valve actuators, etc.
- Control Core: BA190 Edge I/O module, equipped with necessary I/O expansion modules.
- Execution Layer: Variable frequency drives (VFDs), damper actuators, water valve actuators, fan/pump contactors, etc.
- Management Layer: The upper-level Building Automation System (BAS) communicates with the BA190 via the standard BACnet/IP protocol.
Workflow:
- Data Acquisition: The BA190 collects analog signals like temperature, humidity, and pressure via its AI modules; it gathers digital status signals like equipment run status and fault alarms via its DI modules.
- Edge Computing & Logic Control: The BA190's built-in processor executes preset control logic (e.g., PID control, sequential start/stop), configurable flexibly via the web interface without relying on a central server.
- Local Drive Execution: Based on the computed results from the control logic, the BA190 uses AO modules to output analog signals regulating valve openings or VFD frequency; it uses DO/Relay modules to control equipment start/stop.
- Data Upload & Monitoring: All real-time data, equipment status, and alarm information are packaged as standard BACnet objects and uploaded via Ethernet to the BMS for global monitoring and data analysis.
