随着智能建筑走向开放的通信技术，通过内部网甚至通过互联网远程访问建筑自动化系统(BAS)已成为一种常见的做法。然而，BAS历史上是作为一个封闭的环境开发的，在设计时只考虑了有限的网络安全因素。因此，随着可访问性的提高，智能建筑很容易受到网络攻击。介绍了一种用于测试和评估智能建筑中典型基站的网络物理安全的硬件在环(HIL)试验台的开发和性能。试验台由三个子系统组成：(1)通过Modelica的动态模拟，模拟虚拟建筑以及采暖、通风和空调(HVAC)设备的行为的实时HIL仿真器；(2)一组监控虚拟建筑运行并提供本地控制信号以控制HIL仿真器中的暖通空调设备的真实暖通空调控制器；(3)BAS服务器以及基于Web的服务，用户可以通过BACnet网络远程访问暖通空调控制器的时间表、设置点、趋势、警报和其他控制功能。服务器为本地暖通空调控制器生成基于规则的设置点。基于这三个子系统，HIL试验台支持在建筑系统的不同级别进行攻击/无故障和攻击/故障注入实验。由此产生的测试数据可用于向建筑界提供信息，并支持向建筑业转让网络-物理安全技术。
As smart buildings move towards open communication technologies, providing access to the Building Automation System (BAS) through the intranet, or even remotely through the Internet, has become a common practice. However, BAS was historically developed as a closed environment and designed with limited cyber-security considerations. Thus, smart buildings are vulnerable to cyber-attacks with the increased accessibility. This study introduces the development and capability of a Hardware-in-the-Loop (HIL) testbed for testing and evaluating the cyber-physical security of typical BASs in smart buildings. The testbed consists of three subsystems: (1) a real-time HIL emulator simulating the behavior of a virtual building as well as the Heating, Ventilation, and Air Conditioning (HVAC) equipment via a dynamic simulation in Modelica; (2) a set of real HVAC controllers monitoring the virtual building operation and providing local control signals to control HVAC equipment in the HIL emulator; and (3) a BAS server along with a web-based service for users to fully access the schedule, setpoints, trends, alarms, and other control functions of the HVAC controllers remotely through the BACnet network. The server generates rule-based setpoints to local HVAC controllers. Based on these three subsystems, the HIL testbed supports attack/fault-free and attack/fault-injection experiments at various levels of the building system. The resulting test data can be used to inform the building community and support the cyber-physical security technology transfer to the building industry.
