The invention provides an extension unit which is used in a train running monitoring system. The extension unit comprises a shunting interface plug-in, a digital value input plug-in, a digital-to-analogue conversion plug-in, a satellite positioning plug-in, a WLAN plug-in, a level switching plug-in, an Ethernet exchange board and a power source plug-in, wherein the shunting interface plug-in is used for collecting shunting signals; the digital value input plug-in is used for collecting signals such as whistling; the digital-to-analogue conversion plug-in is used for collecting velocity signals transmitted by a velocity sensor, calculating the velocity according to velocity-related information transmitted by a mainframe unit and outputting a signal to drive a double-pointer meter to display the actual velocity and the velocity limit; the satellite positioning plug-in is used for collecting satellite positioning information and transmitting the collected information to the mainframe unit; the WLAN plug-in is used for achieving the wireless data reloading and replacing mainframe basic data through WLAN; the level switching plug-in is used for converting one path or multiple paths of locomotive working condition signals into contact signals allowing the mainframe unit to collect; the Ethernet exchange board is used for providing Ethernet communication connection which is used for large data volume transmission; the power source plug-in is used for converting an external power source into a power source which is suitable for being used by other plugs-in inside the extension unit.
