The invention relates to a goggles tilt state identification system and a corresponding terminal. The system includes: a wide-angle imaging mechanism, which is set in an infectious disease room, and is used to perform real-time imaging actions on the internal environment of the infectious disease room, so as to obtain multiple images corresponding to adjacent moments. Frame wide-angle image; dynamic detection equipment, connected with the wide-angle imaging mechanism, used to identify multiple dynamic targets based on the frame-to-frame variation of each target in the multi-frame wide-angle image, and obtain the latest time corresponding to the adjacent time Multiple static areas respectively occupied by multiple dynamic targets in the wide-angle image, and when the first connecting line and the second connecting line are parallel, a goggles level signal is sent. The tilting state appraisal system of the goggles and the corresponding terminal monitoring of the present invention are effective and stable in operation. Since it is possible to judge on-site whether the position of the goggles worn by the personnel in the infectious disease room matches the position of the personnel's eyes, the correct use of protective equipment is ensured.

The invention provides a CTCS-1 grade-based ground data processing method and vehicle-mounted equipment. The method comprises the steps that a wireless transmission unit receives a transponder group number sent by the host of vehicle-mounted equipment; the wireless transmission unit judges whether incoming line data corresponding to the transponder group number exists in incoming line data information received from ground equipment; and if the incoming line data corresponding to the transponder group number exists in the incoming line data information received from the ground equipment, the wireless transmission unit sends the incoming line data corresponding to the transponder group number and the receiving time of the wireless transmission unit to the incoming line data to the host of the vehicle-mounted equipment host, and if the incoming line data corresponding to the transponder group number does not exist in the incoming line data information received from the ground equipment, the wireless transmission unit does not send the incoming line data to the host of the vehicle-mounted equipment. According to the invention, the correct use of the ground data including the transponder data and the incoming line data by the vehicle-mounted equipment is ensured, the safety of train operation is improved, and various safety accidents such as derailment, overturning, collision and the like of trains due to wrong use of train control data are avoided.
