The invention discloses an early warning method for poor shunting of a track circuit. The method comprises the following steps: S1, selecting early warning indexes, and acquiring sample data and actual measurement data of the early warning indexes, wherein the early warning indexes comprise track voltage, trackside humidity, temperature and the number of times of fault accumulation; S2, processing the sample data and the measured data, and respectively forming an early warning grade set and an index value set, and determining the index weight of each early warning level in the early warning level set; S3, acquiring a comprehensive similarity and difference anti-fuzzy connection degree of each early warning level in the index value set and the early warning level set; and S4, comparing the comprehensive similarities and differences inverse fuzzy connection degrees of the early warning levels in the index value set and the early warning level set, and taking the early warning level with the maximum comprehensive similarities and differences inverse fuzzy connection degree as the early warning level of the index value set. The method has the technical effect of reducing human influence factors in early warning.

    本发明公开了一种轨道电路分路不良预警方法。本发明包括以下步骤,S1,选取预警指标,获取预警指标的样本数据和实测数据,所述预警指标包括轨道电压、轨旁湿度、温度和故障累计次数;S2,处理样本数据和实测数据,分别形成预警等级集合和指标值集合;并确定预警等级集合中各预警等级的指标权重;S3,获取指标值集合与预警等级集合中各个预警等级的综合同异反模糊联系度;S4,比较指标值集合与预警等级集合中各预警等级的综合同异反模糊联系度,以综合同异反模糊联系度最大的预警等级作为指标值集合的预警等级。具有能够减少预警中人为影响因素的技术效果。
