The invention provides a dropper detection device and a dropper anomaly detection method. The dropper detection device is arranged on a dropper of a rail transit overhead line system, and comprises acurrent sensor used for measuring a first current value of a first dropper flowing through the overhead line system when a locomotive runs; a communication module used for communicating with dropper detection equipment arranged on other droppers so as to obtain second current values on a plurality of droppers in front of and behind the first dropper when the locomotive runs; and a main controllerused for comparing the current difference value between the front dropper and the rear dropper of the first dropper based on the first current value and the second current value, and determining whether the dropper is abnormal or not according to the current difference value. According to the method and the device, the problem that the reliability of the rail transit overhead line system dropper is difficult to judge in the prior art can be solved, and the effects of discovering hidden defects of the dropper and conveniently maintaining the overhead line system dropper are achieved.
本发明提供了一种吊弦检测设备及吊弦异常检测方法,该吊弦检测设备设置在轨道交通接触网的吊弦上,包括:电流传感器,用于测量机车运行时流过接触网的第一吊弦的第一电流值;通信模块,用于与设置在其它吊弦上的吊弦检测设备通信,以获取机车运行时所述第一吊弦的前方和后方多个吊弦上的第二电流值;主控制器,用于基于所述第一电流值和第二电流值比较所述第一吊弦的前方吊弦与后方吊弦的电流差异值,并根据所述电流差异值确定是否存在吊弦异常。通过本发明,可以解决相关技术中难以判断轨道交通接触网吊弦可靠性的问题,达到发现吊弦的隐性缺陷、方便对接触网吊弦进行维护的效果。
