某型数/模转换装置通信系统设计

Design of Communication System for Some Digital/Analog Conversion Device

论述了某型数/模转换装置串行通信系统的研制开发及证实。在计算机系统中,串行通信是指计算机与外设之间以及主机系统与主机系统之间数据的串行传送。MCS-51串行口的结构由串行口控制器SCON、硬件接收、发送电路三部分组成。论述了串口工作方式及串口波特率计算,并列出串行通信软件编制流程。在了解了PC机串行通信接口标准后,设计了与PC机通信硬件转换电路,由PC机作为通信的发送端,数/模转换装置作为通信的接收端,实现了对通信系统的验证。在研制、生产过程中起重要作用。

This article discuss the development and the confirmation of the digit/analog conversion device serial communication system. In the computer system, the serial communication is data serial transmission between the computer and the peripheral device as well as between the main engine system and the main engine system. The MCS-51 serial interface＇s structure is composed by three parts, serial port controller SCON, hardware receiving electric circuit and transmiting electric circuit. Discussing the serial interface working and the serial interface baudrate computation, listing the serial communication software flowchart. After having understood PC machine serial communication port standard, it has designed circuit of hardware conversion circuit with the PC machine communication, to make the communication by PC machine the transmitting port, the digit/ analogy conversion device makes the communication the receiving port, it has realized to confirm communications system. It is important role between the development and production process.
