Online fault detection device installed in a rail vehicle and used for a high-speed railway operating component

摘要

In the present disclosure, there is provided an on-line failure detection apparatus installed in a rail vehicle and used for a high-speed rail operation component including a GPS module (1), a noise sensor (2), a 3G module (5), a hard disk (6), a microprocessor (4), a status indicator (3) and a warning sounder (7), input ends of the microprocessor (4) are respectively connected to an output end of the GPS module (1) and an output end of the noise sensor (2). Output ends of the microprocessor (4) are connected to an input end of the status indicator (3) and an input end of the warning sounder (7), respectively. The microprocessor (4) is interactively connected to the 3G module (5) and the hard disk (6), respectively. The above device is reliable and easy to install and maintain; and the components and the sensor thereof are not prone to be damaged. In addition, when a high speed train is operated, the device may detect an early unstable error signal which is subject to several types of interference and quickly provide an alarm.
