蚁群算法在智能断轨监测系统中的应用

Application of Ant Colony Algorithm in Intelligent Broken Rail Monitoring

利用高频载波信号经钢轨传送,通过检测载波信号的强度、波形等参数来监测钢轨断轨时道床的阻抗、容抗、感抗等参数对判断结果影响很大。在不整改道床,尽可能减少施工和维护工作量的要求下,如何规避道床参数变化的影响显得非常重要。通过理论研究结合现场试验,提出了用蚁群算法来解决道床变化对监测准确度的影响。

High frequency carrier signals transmitted by rail are taken to detect the signal strength and waveform parameters, so as to monitor the broken rail, the obtained ballast impedance, capacitance, inductance and other parameters, this method will greatly influence the final judgment. So it is very important to preserve the whole diversion bed, reduce the construction and maintenance workload as much as possible, and avoid the ballast parameter changes. Through theoretical research and field test, the ant colony algorithm is proposed for the solution of the influence of ballast changes on the monitoring accuracy.
