Man-machine interaction device for TCMS and video display and control method thereof

The invention discloses a man-machine interaction device for a train control and management system (TCMS) and a video display and control method; the method comprises the steps: operating a video control obtained through video function configuration development, and triggering a control logic through configuring a control attribute value to achieve a corresponding video function; periodically detecting the change of the control attribute value, and transmitting a control parameter in real time to enable an application layer to obtain the control state information of the video control; and controlling to play a local video of the train control and management system and a network video collected by a train network video device based on the control attribute value, monitoring whether a condition for triggering the change of the control attribute value is met or not in real time in a video display process, and changing the control attribute value when the condition is met. According to the invention, fusion, i.e.
