Another MCU, 89C2051 is used to realize the control of the three rows LED monitor showing coordinates of axis X and Z axis and other state of the system. Charnel A and C of 8155 are used for editor keyboard, which make the inputting or editing of the NC code and data possible. Charnel P1 of 8031 is used for the operation keyboard such as system power on/off and movement of axis X or Z. a programmable parallel I/O chip, 8255, is used to achieve system I/O and the transmission of other information. In summarize, the system developed is characterized by its simplicity, low development cost and high reliability.

在CPU存储器扩展电路设计中， CPU选用MCS-51系列的8031单片机，外扩32K的程序存储器和 8K的数据存储器，分别用于存放系统管理程序、数控加工程序以及运算数据；在显示电路设计中，选用MCS-51系列的89C2051单片机作为从CPU，控制三排LED显示器，用于X轴、Z轴动态坐标以及相关数字的动态显示；在手动键盘和编辑键盘设计中选用8155芯片的PA口和PC口作为行、列母线，扩展矩阵式编辑键盘，用于程序和数据的输入或编辑，同时选用8031单片机的P1口扩展手动键盘，用于系统启动、停止以及运动部件在X、Z轴方向的手动控制；在I/O口扩展电路设计中选用8255芯片扩展输入输出口，用于接收和传送开关量及相关信息。

Improve pixel camera, the digital interpolation to increase ordinary resolution would be tantamount to fraud, in the definition and image quality without any improvement; On the other hand to improve the image quality and resolution, the amount of data is bound to geometry class increase the number of not only USB protocol can not keep up the speed of data transmission, data transmission networks also can not keep up.

摄像头提高像素的话，一般通过数字插值提高分辨率，这就等于弄虚作假，在清晰度和图像质量方面没有任何改进；另一方面若要提高图像质量，提高分辨率，数据量就必然几何级数地增加，不但USB协议的数据传输速度跟不上，网络数据的传输更跟不上。

Some technical problems, such as multi-scale data processing of digital map for transportation GPS service system, are solved by conflation which unites different data source to a new optimal road network data set.
