Embedded system is the most common application form during afterpc times . it consists of hardware and software . embedded system controls the action of the mechanism system by startup devices , gets input information by sensors and process the information by data processing parts 嵌入式系统是后pc时期计算机最普遍的应用形式,系统由硬件和软件两部分组成,通常通过启动装置来控制系统中机械部分的动作,利用传感装置获得系统的输入信息,利用数据处理部件对相关信息进行处理。
The exploitation and study of this system have got great success , compared with the ones of the same type , this system is more open and more easily used to merge with cad and cam , it runs stably , is convenient to be maintained and the interface is friendly and intuitional . its usage can be grasped quickly . according to the input information , it can automatically display different properties of nc codes in different colors , and zoom in or zoom out the figure of tool nose paths dynamically 本系统的开发研究已取得实质性成果,与国内同类的数控系统相比,具有真正的开放性,易于实现与cad cam软件集成,运行稳定,维护方便,界面友好直观,易学易用,能根据输入自动显示不同颜色以区广西大学颀士学赶文募于; m咖ss平台肘开侠尤三劫肛前喊在系统开发研穷分代码的属性,能动态缩放显示刀具轨迹图形,此外,它有较好的多任务性和独立性,能在加工时执行其它windows应用程序而不影响加工,控制器甚至能在pc端操作系统关闭时继续完成加工,可用软件控制面板或硬件操作面板两种方式操纵机床。
These maps will provide further assistance to users when considering input information for the indicators , in particular where the proposal may have geographically specific implications and the user wishes to interrogate map - based environmental information for the areas concerned . figure 5 caset methodology 使用者在考虑有关指标的输入资料时,这些地图将可提供进一步协助,特别是在测试中的建议可能产生涉及地理区域的影响,而使用者希望查询地图上有关地区的环境资料时,帮助更大。
Many research topics had focused on how human can input information into a computer as quickly as possible with high accuracy rate in an easy way . the recognition of handwritten word is one possible solution . but the recognition of nature word writings encountered lots of problems , such as , low writing speed and low recognition rate 手写体识别的研究为解决这个问题提供了一个必要的条件,但是由于传统文字的特点,使得识别的正确率很难取得突破性的进展,而且传统文字记录的缓慢速度也制约了它作为高速录入的解决方案的可能。
Then it presents the function of the input information such as mps ( master production schedule ) , bom ( bill of material ) . finally , it gives all kinds of ways to optimize the computing of mrp , then presents the optimized mrp computing scheme . in chapter 3 , after making a detailed investigation into manufacturing industry , it analyzes the function demand of mrp and design the function accordingly 第三章在对我国制造企业的充分调研的基础上,分析了物料需求计划子系统的功能需求;根据系统的功能需求,用分层数据流图分析了数据间的复杂关系,给出了相应的e ? r图,并设计了相关的数据实体;该章的最后,结合我国制造企业生产管理的实际情况,对物料需求计划子系统进行功能设计,使物料需求计划子系统可以适合各种生产类型的制造企业对于物料需求计划功能的需求。
