The unit and whether the connection between devices is right or not can be judged easily . the functions talked above are not enough to software , the common used edit method and the setup of power plant graphics are also required , they can be realized by inheriting and refer to the method in the units of delphi6 . 0 . as the interface of user and system , except the function of graphic creation it still requires to convert the original data to make it meet the demand of fault analysis 同时该模块作为用户与本系统的计算机接口，除了完成系统图的建立之外，还必须对设备电气参数进行归算，使之满足故障分析与保护整定的要求；要能提供进入故障分析与保护整定模块的接口，完成系统地连接功能；最后为了能正确处理设备的有关参数，本文还介绍了在进行故障分析时将设备参数进行转化的工程处理办法，具有很强的实际意义。
Along with the fast development of computer technology , now pcs ( personal computer ) are powerful of processing data . many works completed by the middle or small size computers not long ago , now can be done by pc computer . the pc control the mca to transfer the nuclear data to pc through the computer interface , then the pc process the data with real time feature 随着计算机技术的飞速发展， pc计算机已有很高的数据处理能力，过去需要中小型计算机完成的多道数据获取，大都可以用pc机完成：将核数据通过计算机接口送入pc机后， pc机能实时地处理数据，同时完成对多道数据采集器的控制。
The writer integrated the short message module and single chip computer effectively , designed a short message single chip computer module - sm02 module , and gave out the arithmetic of realization of module sm02 . the writer also finished and realized the techniques as the distance shingle chip computer data collection , communication , data receiving in monitoring center , controlling and computer fetch communication , and described the software module in the monitoring center all - round . in the end , the writer summarized the procticability of system under research , meanwhile , gave out the research directions to this system for perfect and extension 作者设计出一个基于短消息的无线监控与数据采集系统结构，将短信模块与单片机结合，设计出一个短信单片机模块- sm02模块，给出了sm02模块的实现算法，完成了远端单片机数据采集、通讯、监控中心数据接收、控制与计算机接口通讯等相关技术的实现，论文对监控中心的软件模块作了全面的描述，总结了所研究系统的实用性，并提出了对之进行完善与扩充的研究方向。
The article analyzes the development schemes of the host computer interface card , the adapter principle of the printer and reasons of selecting it . having studied signals of printer ports further , thus i determined the communication mode between the host computer and the slave computer , and designed communication circuit . the question of programming has been discussed 论文分析了上位机计算机接口卡的开发方案，并行打印机接口原理和选用它的原因，研究了打印机端口信号，决定了通信联络方式，设计出上位机通讯硬件电路，并研究了上位机编程问题。
