中文摘要:

      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。

英文摘要:

      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.
