摘　　要：MS/TP协议作为BACnet标准的成本低廉、实现简单的数据链路选择,在楼宇自控设备中使用广泛。为有效地实现BACnet设备与实时数据库之间的通信,介绍了BACnet标准与MS/TP协议,开发了一个基于RS485通信方式和MS/TP技术的驱动程序,并分析了其工作过程。实验测试结果表明,该程序的运行符合BACnet一致性要求,具有简单、高效、实时性好的特点。MS/TP is widely used in building automation devices, which is a low-cost and simple-to-implement data link protocol for BACnet open standard. The features of BACnet standard and MS/TP protocol are briefly introduced. In order to realize the data communication between BACnet devices and real-time database, a driver based on MS/TP and RS485 is developed, and its work procedure is analyzed. The experiment results show that the designed driver conforms to the BACnet consistency, and has the characteristics of simple, efficient and good real-time.
