智能仪器与计算机一样,是执行命令的机器。在智能仪器中,命令主要来自键盘和IEEE488接口。监控程序的主要任务就是接受、分析并执行这些命令,是整台机器的核心部分。在研制智能仪器时,监控程序设计的优劣直接影响仪器的质量和用户使用的方便程度。采用状态综合法设计监控程序是最方便的,只需用少数几个功能键,使一键重复或几键交叉使用,即可组建出许多命令来。这样,在面积较小的仪器操作面板上有可能建立一个功能复杂,操作简便的键盘操作系统。本文以研制智能信号源为例,介绍状态综合法设计监控主程序的基本思想。
As with computers, smart instruments are machines that execute commands. In smart instruments, commands come mainly from the keyboard and the IEEE488 interface. The main task of the monitoring program is to accept, analyze and execute these commands, is the core of the entire machine. In the development of intelligent instruments, monitoring the pros and cons of program design directly affect the quality of the instrument and user convenience. The state synthesis method is the most convenient way to design a monitoring program. Just use a few function keys to make one key repeat or a few key cross usage, you can create many commands. In this way, it is possible to create a functionally complex and easy-to-use keyboard operating system on a smaller instrument panel. In this paper, the development of intelligent signal source, for example, introduces the state synthesis method to monitor the design of the main idea of the main program.
