摘　　要：该文简要介绍了在农业设施中以新型单片机AT89S8252为核心的测控仪表的组成特点及其硬件与软件的优化设计方法。重点介绍了在农业设施群中,通过多机通信技术,用一台PC机集中数据采集、管理、控制各个设施中的测控仪表的主从多机工作模式,以及在这种工作模式中,单片机与PC机的串行通信接口硬件设计、通信软件设计、PC机的界面设计特点及设计方法。这些设计使得该系统在农业设施中推广成为可能。The characteristics of structure and optimum design of the hardware and software of the measuring and controlling meter based on a new type micro-controller AT89S8252 were introduced briefly in this paper, which was used in agricultural facilities. The design method and the design characteristic of hardware, software and interface of serial communication between microcontroller and computer station in this system were introduced emphatically. The excellent design method enables it to become practicable to popularize the autocontrol system in the group of agricultural facilities.
