Embodiment Construction
[0020] Below in conjunction with specific embodiment and accompanying drawing, the present invention is further described:
[0021] like figure 1 As shown, a train running state monitoring system based on data projection mode change includes a data acquisition module, a data processing module, and a monitoring module. The data acquisition module used to collect acceleration and displacement is equipped with a pre-130Hz low-pass filter circuit, an acceleration sensor and a displacement sensor. The above two sensors are installed on the train body, the upper floor of the body bolster, the frame, the axle gearbox, etc. ; The data processing module for processing the collected data includes an arithmetic unit for data calculation and a memory for data storage; the monitoring module is a terminal display or a fault discriminator. The sensor filters the collected data through a pre-filtering circuit, and then transmits the data to an arithmetic unit. The arithmetic unit processes t...
