Human-computer interaction unit and interaction method for railway locomotive

The invention discloses a human-computer interaction unit and interaction method for a railway locomotive. The human-computer interaction unit performs data communication with an optimization controller, and includes a power supply, an interface driving module, a key input module, a display management module, a MCU main control chip and a monitoring management module, wherein the MCU main control chip is used for controlling the optimization controller to perform journey initialization, controlling the optimization controller to enter or switch to a corresponding locomotive running mode according to a control signal issued by the key input module after the journey initialization is finished, and receiving locomotive running state parameters fed back by the optimization controller, and the monitoring management module is used for regularly receiving verification data issued by the optimization controller and comparing whether the verification data are consistent with currently received locomotive running state parameter data, and if the data are inconsistent, the display management module is controlled through the MCU main control chip to perform alarm display and issue an alarm signal to the optimization controller. The human-computer interaction unit provided by the invention pays attention to data related to a locomotive in real time, thereby improving driving efficiency; and at the same time, the disadvantage that a locomotive type is not matched with an optimization system is effectively solved.
