data bus in meaning in English
数据总线输入
Examples
- Use 40pcs led display a0 - a23 address bus and d0 - d15 data bus in binary
用40个led做二进位码显示 - Use digits display a0 - a23 address bus and d0 - d15 data bus in hexadecimal
用数字显示器做十六进位码显示 - The main body of the new system hardware parts is ipc , the intelligence sport control card pcl - 839 is embedded in the isa standard slot of ipc . the data is commutated between the card and the ipc throught these internal data bus in pc . the machine tool will be controlled by the data . the exterior data is commutated between the pcl - 839 and exterior equipments by pcld - 782 / 785 . the development of the software is to adopt the visual c + + 6 . 0 . because the intelligence sport control card , pcl - 839 , has the function of edit and translate programme by its own application prog839 . exe . there are a great deal of function in the application , which reduce a great deal of work to develop the new system . the open - type structure is adopted , so it has a lot of space to develop better and better
本数控系统硬件部分利用工业ipc机作为主体,智能运动控制卡pcl - 839插在其isa标准插槽上,通过内部总线实现数据的交换和控制从而达到控制三座标数控机床的目的,外部数据的输入输出部分采用pcld - 782和pcld - 785输入输出卡;软件的开发是采用visualc + + 6 . 0为开发工具,由于pcl - 839智能运动控制卡具有自行编译功能,而且自行封装了prog839 . exe编译软件提供了大量的可调用的功能函数,使开发者不必重复开发数控代码的编译等工作,减少了数控系统开发的工作量,同时控制系统软件采用开放式结构,具有可重构、可扩展的特点,给用户留有二次开发的余地。 - After requirements analysis and argumentation of design plan in detail from two aspect , hardware and software , we bring about a design plan that in development of system software , kingview is used as the main tool , vb is the second tool and the rs485 is adopted as data bus in implementation of hardware network
作者在对国内外监控系统发展现状与项目需求进行分析的基础之上，从硬件、软件两个方面详细论证了系统的设计方案。提出硬件系统采用rs485的总线式网络结构，软件系统采用以组态王为主、 vb为辅的系统开发方案。
