Source abstract
Abstract
In order to ensure the safe operation of subways, it is necessary to detect the metro gauge and track geometry in time. However, the manual detection and the large rail inspection car is inefficient and expensive. Therefore, we have developed a multi-sensor integration detection and analysis device. Sensors, such as a laser scanner, a gauge sensor, an angle sensor, and a single-chip computer, are integrated into a rail inspection trolley, and the functions of gauge detection, gauge analysis, rail gauge calculation, and superelevation calculation are realized. Through the calibration of an odometer and a sensor, the accuracy of the device can meet the requirements of the standard. The device is applied to Changsha Metro Line 3 to detect and analyze the gauge and track geometry state. Finally, the device realizes the functions of the gauge intrusion alarm, automatic input of graphics and gauge intrusion data, automatic identification of sleepers, and automatic collection of track geometry data.
