railway crossing speed measuring track circuit crossing control center
为了实现铁路道口列车接近定时报警，提出了一种基于轨道电路的列车测速系统设计方法。在铁路道口的远端设置两段相邻的25m轨道电路，列车接近时，两段轨道电路依次动作。采用单片机电路测出两段轨道电路动作的时间间隔，即可计算出列车的行驶速度。将列车的速度信息发送给道口控制中心，确定道口合理的关闭时机。实验结果表明，测速精度可达到0．1m／s，能够满足系统的要求。

In order to realize the warning at the fixed time for the trains closed to the railway crossing, we propose a design method for speed measuring of railway crossing based on track circuiL Two 25-meters track circuits are set at far end of railway crossing, when the trains close to the railway crossing, the two track circuits operation in turns. The single-chip circuit is used to calculated the time interval of the two track circuits operation, then the speed of trains is known and is sent to the crossing control center and we can determine the reasonable time about the crossing closed. Experimental results show that speed accuracy can be achieved 0.1m/s that can meet the system requirements.
