基于Pocket PC的道路曲线统一计算研究与软件实现

Study and software realization on unified calculation of route curves based on Pocket PC

以全站仪为例介绍Pocket PC串口通讯过程,并基于道路平面曲线元通用电算数学模型,推导曲直法道路线路统一计算的数学公式。利用eMbedded Visual C++编程工具,实现了WindowsCE.NET系统下,Pocket PC与全站仪和GPS接收机之间的串口通讯,并实现其道路平曲线测设、缓和曲线参数计算等功能。

The serial communication processes are introduced with the total station as an example, and the mathematical formulae of route curve unified calculation are deduced with the zigzag method based on the general computer calculation mathematical model of plane curves. With the development environment of eMbedded Visual C ＋＋ , the serial communication between Pocket PC and total station or GPS receiver is realized in the system of Windows CE. NET, and the functions of plane curve survey and transition curve parameters calculation for roads are also realized.
