On the one hand of hardwar : first of all , the thesis introduces the interiror structure of pic18f8260 and its distinguishing with other singlechip ; secondly , having narrated the structure and performance of gsm communicate module - tc35i module and the hardware performance process of communications interface of gsm ; thirdly , having studied the drived principle and dynamic scanned circuit of led ’ s panel ; lastly , having put forward serial interface circuit which the application of system . on the other hand of software which have accomplished the running of hardware : in design , utilizing mscomm control to realize the serial communication between computer and cell phone , utilizing at command to realize the cell phone control and sms receiving and sending operation , the pdu ( protcol data unit ) 设计上,利用mscomm控件实现计算机与gsm模块间的串口通信,使用at指令实现对gsm模块的各种控制和短信的收发,分析发送和接收短消息的pdu ( protcoldataunit )格式、短信内容、手机号码、 smsc (短消息服务中心)号码等;单片机与pc机之间的通信采用pic中c语言和c + +语言编程,以中断方式实现pic18f8260与led的通信,同样利用mscomm控件从汉字字库的提取点阵码,最后显示在led上。
In the system , the sampling circuit is equipped with the 8051 scm to gather the switch and simulate single , and the system straightly manipulate each register of utrt ( 8250 ) with interrupted way to control the serial communication of the scm sampling module . in this way we can solve the problem of hard control of the multi serial communication in windows system 对于开关量、模拟量信号采集电路采用以8051单片机为主体的智能采集模块系统，并通过直接操作uart ( 8250 )各寄存器以中断方式对各路单片机智能采集模块进行串行通信控制，解决了在windows系统中多串口通信不易控制的问题。
System is made up of two parts of hardware and software , hardware part include ecg signal receive , enlarge and filter circuit and gather circuit two parts among them , design isa and pci two bus collection card of form separately ; software part include and can programme and run side by side 8255 interface and cpld and interface software design of ad574a , using interrupt way to design the software of data collecting , and realization of data compress , and software design of administrative system 本系统由硬件和软件两部分组成，其中硬件部分包括心电信号的接收、放大和滤波电路以及采集电路两部分，分别设计了isa和pci两种总线形式的采集卡；软件部分包括可编程并行接口8255和cpld与ad574a的接口软件设计、中断方式数据采集系统的软件设计、数据压缩以及病例管理系统的软件设计。
Besides the design of the hardware construction for shape meter , the software system written in visual basic 6 . 0 is also developed . the real - time data acquisition and conversion system worked in interrupt mode is accomplished by means of loading dynamic linkage library of pcl - 812pg enhanced multi - lab card . the converted data processing will be operated then , for example , scale operation , comparison , graphic display , data storage , etc . the adjusting values for the shape control are also calculated in it 本文在参考大量带材标准板形、轧制初始量设定、调节量计算研究的基础上，确定了标准板形模型、设定模型、调节控制模型等数学模型；并给出了其相应的算法；完成了板形仪计算机控制系统的硬件设计，并在此基础上，应用高级开发语言visualbasic6 . 0 ，通过加载pcl - 812pg多功能数据采集卡的驱动程序后，调用动态链接库（ dll ）中的函数的方法，完成了信号中断方式下的实时数据采集，采集的数据经计算机作标度变换、对比、图形显示、存储等处理，并提供了用于板形闭环控制的调节量。
