摘要
为方便铁路养护维修,实现设备与病害在地图中的定位,以甘泉铁路管养修信息系统开发为例,探讨了里程与坐标相互转换的方法。主要阐述了里程点坐标转换的数学模型、计算方法和实现过程,并通过实例验证了转换的精度和可靠性。结果表明,该算法易于编程实现,转换精度较高,适用于铁路养护维修中设备与病害的定位。
To facilitate the maintenance and repair of railways and locate equipment and disease in the map, theMaintenance and Repair Information System of Gan-Quan Railway was selected as an example and inter conversionmethod between mileage and coordinate was discussed. This article mainly expounded the mathematical model,calculation method and implementation process of conversion, verified the accuracy and reliability of this methodwith example. The results showed that the conversion method was easy to program and the conversion precision wasrelatively high. So that it was suitable for the location of equipment and diseases in the railway maintenance and repair.
