Chengdu Logistics Information Technology Co.,LTD, Chengdu 610036) Abstract: Nowadays, there are three methods of Digital Broadcasting Station, GPRS and 3G Communication Technologies that railway signals or other information transmit enterprise locomotive or video or some relative information feedback to the control centre. National railway uses GSM-R special network. Since there are advantages and disadvantages among the above-mentioned methods, this paper is first to use mesh technology into control of enterprise locomotive running according to the experience of mesh technology in the north America railway system. Moreover, DGPS technology is in the application of enterprise locomotive running control, which is the new method other than the method of making use of railway circuit signal to monitor locomotive really. The visualization of Railway information and locomotive running, the feedback video of locomotive electronic tag, security alarms of DGPS high-precision of navigation capability and real-time playback of locomotive track and speed, all these functions makes the railway real-time monitor visualizing. This paper discusses the technology based on wireless mesh networks and DGPS in detail, which is the important organization and ke
