Design and realization of remote updating of onboard LDP board program in CMD system of HXD2B locomotive
The paper introduces the implementation process of remote program updates between the onboard LDP and the ground server.By utilizing the 4G communication function of the onboard LDP and the browser/server architecture mode,we designed and implemented the program updates of each onboard LDP board to improve update efficiency,reduce maintainer's work time,and alleviate the tedious and time-consuming maintenance burden due to manual updates onboard.
