摘　　要：设计了一种轨道电路叠加电码化入口电流的计算程序,采用二端口网络级联的计算方法,将若干个二端口网络看做一个二端口网络,再利用二端口网络自身参数的特性,形成计算算法。利用VBA集成开发环境,设计了轨道电路叠加电码化入口电流的计算程序,该计算程序使用EXCEL界面,计算速度快,利于数据保存。本文以2000频率的电码化信号为例进行了计算说明,与ZPW2000电码化电路模拟设备搭接的试验电路测试结果近似相等,理论计算与实际模拟电路相互之间很好的得到了验证。Designing a program of entrance current calculation of track circuit overlap coding.Using the calculation method of cascaded two port networks,you can put aplurality of two port network as a two port network,and using the characteristic parameters of two port network.Using the VBA integrated development environment,design program for entrance current calculation of track circuit overlap coding,the program using the EXCEL interface,has the advantages of fast computing speed and convenient data storage.In this paper,the 2000 frequency conding is calculated for example,the calculation results of the program and the actual analog test results are approximately equal.The theoretical calculation and the actual analog circuit are well validated.
