Deep Application of Industrial Computers in Building Automation: The Integration Revolution of BA Systems and Air Conditioning Control
In the wave of smart city construction, Building Automation Systems (BAS) serve as the "nerve center" of buildings, optimizing both energy efficiency and spatial experiences by integrating subsystems such as air conditioning, lighting, and security. However, issues such as incompatible equipment protocols from different manufacturers, isolated data silos, and fragmented control logic in traditional buildings have become core pain points restricting intelligent upgrades. This article will delve into how industrial computers achieve deep integration of BA systems and air conditioning control through technological reconstruction and explore how intelligent terminals, represented by the USR-EG628, are propelling building automation into a new era of "omni-domain collaboration."
Core Challenges in Building Automation: From Equipment Stacking to System Collaboration
1.1 "Language Barriers" of Heterogeneous Protocols
In modern buildings, air conditioning systems commonly adopt the BACnet protocol, while lighting, elevators, and other equipment may use protocols such as Modbus, LonWorks, or KNX. This coexistence of multiple "languages" necessitates data interaction through protocol conversion gateways, which not only increases deployment costs but also affects real-time control accuracy due to protocol conversion delays (typically ranging from 200 to 500 ms). For example, a commercial complex frequently experienced indoor CO₂ concentration exceedances due to protocol incompatibility between its air conditioning and fresh air systems, ultimately resolving the issue by deploying multi-protocol industrial computers.
1.2 "Spatial and Temporal Fragmentation" of Control Logic
Traditional BA systems employ a centralized control architecture, with all decisions relying on cloud servers. This model faces two major dilemmas when dealing with large-scale buildings: first, data transmission delays (often reaching 1-3 seconds for round trips to the cloud) result in lagging control responses; second, there is a high risk of system paralysis during network outages. A data center project once suffered an air conditioning system失控 (loss of control), triggering a server outage and direct economic losses exceeding one million yuan due to network failures.
1.3 "Blind Spot Dilemmas" in Energy Management
Air conditioning systems account for 40%-60% of building energy consumption, but traditional BA systems can only obtain equipment operating statuses and cannot deeply analyze energy consumption compositions. For example, a hospital's air conditioning system had consistently high annual energy consumption, which was diagnosed to be caused by failed linkage between the chiller and terminal equipment, resulting in "high flow and small temperature difference" operation, with energy consumption per unit of cooling capacity 32% higher than industry standards.
The Solution Path of Industrial Computers: Reconstructing Control Architecture with Edge Intelligence
2.1 Multi-Protocol Fusion: Breaking Down Data Silos
The new generation of industrial computers, represented by the USR-EG628, enables "plug-and-play" device data through built-in parsing engines for 12 industrial protocols, including Modbus, BACnet, and KNX. Its unique protocol mapping technology can abstract devices using different protocols into a unified data model, for example, automatically converting register data from a Modbus temperature sensor into a BACnet standard object, allowing the air conditioning system to directly read temperature data from the lighting area and laying the foundation for cross-system linkage.
Typical Case: In a smart park project, the USR-EG628 integrated LonWorks protocol security sensors, Modbus protocol smart meters, and a BACnet air conditioning system, enabling scenario-based control where "when the conference room access control is opened, the air conditioning air supply volume is automatically adjusted and the lighting system is联动 (linked)." The equipment integration period was shortened from 3 months to 1 month.
2.2 Edge Decision-Making: Reshaping Control Latency
The 1 TOPS AI computing power and WukongEdge edge computing platform equipped on the USR-EG628 enable complex control logic to be executed locally in a closed loop. In air conditioning control scenarios, it can achieve:

Fault Pre-Diagnosis: Through vibration sensor data and motor current analysis, it predicts equipment failures 72 hours in advance, reducing unplanned downtime rates by 65%.
Data Validation: Among the 500 USR-EG628 units deployed in a smart park in Shanghai, the comprehensive energy efficiency (COP value) of the air conditioning system increased by 22%, with each unit saving 70,000 yuan in annual electricity costs, equivalent to reducing 37.68 tons of carbon emissions.
