Research on automatic upgrade of TDCS software based on IOCP

With the rapid development of railway transportation, TDCS (Train Dispatching Command System) system as the key equipment of traffic control, has been increasing the demand for upgrade deployment system, which brings challenges to the maintainers under the C/S architecture. According to the characteristics of TDCS system security management and construction and overcoming the inconvenience of deployment, upgrade and maintenance in C/S mode, this paper puts forward a automatic upgrade solution for client software in TDCS system, which has been implemented in VS2010 development platform. The test has been carried out in the the system debugging environment, and the result is very good. It not only improves the speed of software upgrade, but also reduces the maintenance cost greatly.
