GPS农田平地机土方量及设计高程计算软件开发

使用全球卫星定位系统(GPS)农田平地机进行平地作业前,要对平地作业地形进行测量,计算出平地作业土方量,包括挖方量和填方量,根据挖方量与填方量相等的原则,再计算出平地机设计高程,将设计高程导入GPS平地机自动控制系统里,可使GPS农田平地机更精准设定高程,从而自动控制平地机的作业。传统的手工计算土方量及设计高程方法过于复杂,为了提高计算工作效率,方便用户使用,开发了基于VB 6.0编程软件的平地机土方量及设计高程计算软件。经过田间平地测试检验,该软件能够提高平地作业效率。

Calculation Software for the Earth Volume and Design Elevation of GPS Farmland Grader

Before using the Global Positioning System (GPS) field grading operation, we should measure the topographic fea-tures and calculate the earth volume of grading operation, including the excavation volume and filling volume, and then cal-culate the design elevation of grader according to the principle of equal amount of excavation and filling volume. The design elevation was then input into the automatic control system of GPS grading machine, which provide a more accurate height setting, as well as automatic control of grader work. As the manual calculation of earthwork and elevation design method is too complicated, a software for calculating the earth volume and design elevation of grader was developed based on VB 6.0 programming software in order to improve the computational efficiency. Field leveling test,showed that the software could im-prove the efficiency of flat ground operation.
