It is an open - structured system for users to edit , revise and develop more functions 该系统应是开放式结构,可供用户编辑、修改,并能进行功能开发。
Aiming at the function and performance limitations of traditional special cnc or current pc - based open - structure cnc , a brand - new cnc platform designing scheme of multi - layer open - architecture is presented , based on embedded - mcu calculation and management core , and three kinds of expanding mode of software , hardware and interface . by using double system working ram and boot rom technology , an independent re - development interface is set on the hardware platform to realize customized function ’ s simulations and verifications online , which makes all the expanding or re - configuring on basic cnc platform are all safe and restorable 本文针对传统专用数控系统的结构封闭、交互形式不通用和配置扩展不灵活方面的劣势以及当前pc模式开放结构数控的体积庞大、开放程度不高和实时可靠性不强的局限,创新性地提出了以基本cnc框架+软件、硬件和接口三种扩展形式为特征的层次化开放结构的嵌入式cnc硬件平台,并采用双存储区技术进行了cnc系统在线仿真校验机制和安全保护机制的方案设计。
Intelligent distance exercise system ( ides for short ) is an internet - based exercise system in character with intelligence , open - structure , discipline - cross and multi - layer . using this system , we can finish exercise course on computer including subject design , assignment , answering questions , auto distinguishing , evaluating and summing - up 智能型远程作业系统是一套基于互联网的智能型、开放式、跨学科和多层次的远程作业系统,该系统能够实现题目设计、作业布置、学生答题、自动批阅和评讲总结等作业环节的全程微机化。
