摘　　要：往往对于小型,专用智能仪器,直接编写专用的监控程序才能满足仪器的技术要求。传统的智能仪器监控程序通常采用"状态变量法",此方法往往采用多级表格,结构复杂,而且只适合"单进程"情况,系统进程遇故障恢复能力差。本文提出一种"功能点"法,采用新的监控程序结构,兼具"多进程"并发执行和系统进程故障恢复的特点,特别适用于具有通信模块的小型智能仪器系统。In the case of the miniature special-purpose intelligent instrument development, the developer＇s monitor is a good choice to satisfy the technical requirement. The state variable method, the traditional way for monitor development, needs to look up multiple tables and results in complicate structure, poor process restoration. This paper proposes a novel method involving functional nodes and newly structure in monitor, which features concurrent process and process restoration; it has found applications in the miniature instrument development.
