Locomotive-mounted Power Battery Pack Fire Safety Control System and Method

A locomotive-mounted power battery pack fire safety control system, comprising a power battery pack, a power battery control system main controller, a rolling stock microcomputer system and a rolling stock display screen connected in turn respectively, and characterized in that:

• the power battery pack is a closed installation isolated from external air, an inert gas injection pipe, a smoke detector and a temperature detector are arranged at the top end inside the power battery pack, and the smoke detector and the temperature detector are connected with the rolling stock microcomputer system;
• an inert gas storage device is arranged outside the power battery pack, the inert gas storage device is connected with the inert gas injection pipe, and an inert gas is stored in the inert gas storage device;
• and
• a pressure detector and an inert gas injection control switch are arranged in turn on a pipeline through which the inert gas storage device discharges an inert gas to the power battery pack, and the pressure detector and the inert gas injection control switch are connected with the rolling stock microcomputer system.
