摘要
针对不同厂商、不同系统的楼宇自控设备互操作、互通信的局限性,分析了BACnet/IP技术和实时数据库,设计开发了一种基于BACnet/IP技术的实时数据库Das Rdb的设备驱动程序。该设备驱动程序采用UDP通信方式,通过调用每个BACnet/IP设备的标准接口函数来驱动实时数据库Das Rdb分别进行写操作和读操作,能够有效地实现BACnet/IP设备与实时数据库Das Rdb之间的通信,从而使楼控设备的互操作成为可能。现场工程应用表明,该程序的运行契合BACnet的一致性要求,具有简单、高效、精确度高、实时性好的特点。
Aiming at interoperability and mutual communication limitations of building automation equipments for different manufacturers and systems, a device driver of Das Rdb real-time database was designed and developed independently based on BACnet / IP technology after the BACnet / IP（ data communication protocol for Building Automation and Control network / Internet Protocol） technology and real-time database was analyzed. The device driver adopted UDP communication mode to write and read operations respectively by driving the real-time database Das Rdb. This can effectively realize the communication between BACnet devices and Das Rdb real-time database, and make it possible for building automation equipments to interoperate. The field engineering application shows that the designed driver conforms to the requirements of the consistency of BACnet, and it is simple, efficient, and of high precision and good real-time.
