摘要
基于ARM7和μC/OS-Ⅱ操作系统的数据采集系统采用ZLG7290实现人机接口;利用键盘设置报警上下限,实现数码管显示数据采集值和实时时间;说明了按键键值处理的基本程序;阐述了数码管显示程序的主要思路;描述了键盘管理程序设计思想,给出了键盘管理函数和报警上下限处理函数的流程图;基于UDP协议的数据采集画面中显示了实时数据采集值和接收到的实时时钟信息;实现了基于UDP协议显示从E2PROM中读取数据采集值的功能;采用UDP通信协议很好地实现了远程数据采集与监视。
Based on ARM7 and μC/OS-II operating system of data acquisition system, ZLG7290 is used to realize human-machine interface. The keyboard is used to set the alarm limit to realize digital tube display data acquisition and real time. The basic procedure of the key value processing is illustrated. The main idea of the digital tube display program is expounded. Descriptions of the keyboard management program design thought, keyboard management function and flow chart of upper and lower limit alarm function are given. Data acquisition and real-time clock information received are shown in the real-time data acquisition panel based on UDP protocol. The function of displaying data acquisition value read from the E2PROM based on UDP protocol is realized. The UDP communication protocol is applied to achieve a good remote data acquisition and monitoring.
