[0029] Such as figure 2 , image 3 As shown, a method for updating vehicle-mounted data refers to: the PC obtains the basic railway data of train operation, uses the online programmer management software in the PC to convert the format of the basic railway data to obtain a data file, and then writes the data file into in the online programmer. The on-line programmer is a movable device. When in use, the staff takes the on-line programmer to each train and connects the on-line programmer to the monitoring and recording plug-in, so that the data files can be updated to the monitoring and recording plug-in. The above-mentioned monitoring and recording plug-in is located in the train operation monitoring device and replaces the original EPROM device. It receives the transmitted data files and transmits the data files to the train operation monitoring device.
[0030] Such as Figure 4 As shown, the PC is equipped with LKJ online programmer management software. The LKJ online p...
