【摘要】 分析了小型测控装置基本结构和任务,研究并构建了硬件通用平台和任务表模型,应用面向对象技术,将各种任务抽象为任务类,并对硬件的操作、数据处理,以数据和函数的形式封装为类;通过对任务调度的研究,得到了最佳调度周期及调度周期动态调整的算法;研究了代码生成器算法,并用其生成任务代码和调度程序代码。实际运行表明:采用通用平台设计的小型多功能测控装置具有开发周期短、通用性强、运行良好、灵活方便和性能可靠的特点,可广泛应用于工业自动化中。更多还原

【Abstract】 The basic structure and tasks of general hardware and software platform of mini-type multi-function measuring and controlling are analyzed,the table of tasks model are studied and constructed.All of tasks are abstracted to the task class that operator hardware,data processing is enveloped using OOP.The optimized arithmetic of period of dispatch and adjustable dynamic arithmetic is obtained.The code generator is studied,and then the tasks codes and dispatch program code are generated using code generator.It is accounted that the device which developed using general platform have shorter period of development,more than general,well operation,more reliabilities,and it can be used in industrial autoimmunization widely.更多还原
