基于Visual C#的25 Hz相敏轨道电路计算软件的设计

摘要

Based on the Visual C# language, this article designed calculation software for 25 Hz phase sensitive track circuit. On the basis of testing the parameters of track circuit equipment, the software constructed the four-terminal-network-model using the theory of uniform transmission line, calculated the track circuit for normal state and shunting state, obtained all the equipment input and output voltage, power adjustment, shunt and other information in the condition of adjusting state, adopted exhaustive method to estimate the ballast resistance of track section. The calculation results were verified through the standard atlas of contrast and indoor test, the result was accurate.%设计了一种基于Visual C#的25 Hz相敏轨道电路计算软件,在测试出轨道电路设备器材参数的基础上,采用均匀传输线理论构建其四端网络模型,分别对轨道电路的调整状态和分路状态进行计算,得出调整状态下各设备器材的输入输出电压、调整功率、分路情况等信息,并采用穷举法估算出轨道区段的道床电阻.最后,通过与标准图册对照和室内试验的方法对软件的计算结果进行了验证,结果准确.
