Distributed man-machine active safety interaction system

The invention discloses a distributed man-machine active security interaction system, which comprises a base station, identification cards, an alarm device and an information processing module, and is characterized in that the identification cards are respectively calibrated as a white list card and a black list card; if the real-time distance of the white list card is within the alarm distance range, the alarm device broadcasts first prompt information; if the real-time distance of the blacklist card is within the warning distance range, the alarm device and the blacklist card give an alarm at the same time, and the equipment stops working; and if the real-time distance of the white list card is within the warning distance range, the alarm device broadcasts second prompt information. The key point of the control is that a brand new space tetrahedron positioning method is adopted on the basis of UWB two-way real-time communication, approaching personnel are accurately positioned, and meanwhile, an alarm promp
