Abstract: With the development of train integrated control technology and the gradual expansion of rail transit network, more and more demands have been put forward for the refurbishment of line infrastructure, the sectional commissioning of lines and the interconnection between line networks, which puts forward higher requirements for the control and management mode of upgrading electronic map. This paper analyzes the shortages in the way of data preparation and updating of the current Communication Based Train Control (CBTC) system electronic map and puts forward a new control and management scheme of upgrading electronic map to achieve higher maintainability, reliability and safety of electronic map data.
