For example, the type of the track fault, the geographical location and the detection time corresponding to the track fault, and the like are determined. Then, the on-board host 12 may form corresponding alarm information according to a preset alarm setting rule for the track fault information, thereby obtaining a preliminary track fault detection result. Wherein, the warning of predetermineeing sets up the rule and can sets for according to the actual production demand, for example, the track fault type of fastener disappearance sets up to the one-level trouble to correspond and set up one-level alarm information.

That is, the server 203 can more intelligently detect and judge the track image with suspected fault that the vehicle-mounted detection device 10 cannot determine, so as to obtain a final fault analysis result. Accordingly, the display module 204 displays the failure analysis result.
In an alternative embodiment of the present invention, as shown in fig. 1c, the ground control center 20 may further include an image processing module 205 for performing fault analysis on the received track fault detection result alone. That is, the image processing module 205 may complete a function of more intelligently detecting and judging the track image with the suspicion of failure that the in-vehicle detection apparatus 10 cannot determine in the server 203.

That is, the image processing module 205 may process the track image independently from the server 203, or may process the track image integrated within the server 203, which is not limited in the embodiment of the present invention.

Meanwhile, operation and maintenance personnel can also utilize a human-computer interaction module in the track fault detection system or utilize a ground control center to retrieve track images. For example, the track fault detection system may perform keyword tagging on the track image, so that the operation and maintenance personnel may retrieve the corresponding picture by inputting keywords such as a fault problem. Alternatively, the operation and maintenance personnel can also directly search for the image condition. For example, among all the track images, one type of track image of the type of the fastener failure at the location is searched. The operation and maintenance personnel can also manually recheck the track fault identified by the track fault detection system, optionally, the manual recheck can be executed in a human-computer interaction module or a ground control center, and the accuracy of fault positioning can be further improved. Correspondingly, the track fault detection system can generate a corresponding maintenance work order according to the final fault analysis result.
