Abstract

The invention relates to a steel rails fracture vehicle-mounted non-contact fast detection technique, comprising n wheel pairs, 2n sensors and 2n resonance demodulation convertors, wherein n wheel pairs are arranged in locomotive and vehicle; the 2n sensors are positioned on 2n axle boxes of the wheel pairs, which are used for detecting the wheel impact situation caused by fractured rails; 2n sensor signals are transported in parallel and synchronously to 2n corresponding matching resonance demodulation convertors; 2n resonance demodulation signals are transported in parallel to 2n corresponding AD channel of computer, which are output by 2n resonance demodulation convertors; the resonance demodulation signals are controlled by a plurality of rotational speed control signals output by a plurality of rotational speed interfaces; the speed automatic tracking and uninterrupted continuous sampling is processed to obtain 2n continuous samples which is obtained from the monitoring of each sensor to each trail and divided into two groups; the samples are sent to a computer fractured rail diagnosis expert system, which are real-time analyzed, diagnosed and detached out of the steel rails fracture information by the computer fractured rail diagnosis expert system; the real-time mileage coordinates are obtained from locomotive monitor system; the steel rails fracture information sends out the alarm through the 485 interface together with the real-time mileage coordinates.
一种钢轨断裂车载非接触快速检测技术,含有安装在机车、车辆的n条(n≥2)轮对的2n个轴箱上的2n个用来检测断裂轨道对车轮所发生冲击状态的传感器,并将该2n个传感器的信号并列、同时送到对应匹配的2n个共振解调变换器;而后将2n个共振解调变换器输出的2n个共振解调信号并列送到计算机的2n个对应的AD通道,由转速接口输出的转速控制信号控制,进行车速自动跟踪的、不间断的连续采样以获得每个传感器监测每条轨道的2n个分为两组的连续样本,送到监控计算机的计算机断轨诊断专家系统,由其对所获样本信息进行实时分析诊断、分离出钢轨断裂的信息,最后与通过485接口与从机车监控系统获得的实时里程坐标一同发出警报。
