摘　　要：针对目前支持多协议的智能仪表存在的串口不足问题,在研究了智能仪表软件架构、串口接收点和串口发送节点结构的基础上,设计了一种支持多串口同时抄表的智能仪表程序。同时,较详细地阐述了设计中支持多协议的串口接收程序,以及支持多协议的串口发送程序的设计流程。实践证明,该设计可以有效地解决智能仪表协议的多样性和串口数量有限之间的矛盾。In view of the serial port shortage problem that the integellent meter of multi-protocol has, the paper based on the study o{ the intelligent instrument so{tware architecture and serial port to receive/send node structure, designs a program that supports the multi se rial ports simultaneously. At the same time, more detailed description is given of the receiver program designed to support multi-proto col, as well as the design process that supports multi-protocol serial port to send the program. Practice proves that the design can ef{ec tively solve the contradiction between the limited diversity and serial number of the smart meter agreement.
