[0029] To meet the requirements of system timeliness, reliability and the like, the open-pit mine intelligent safety helmet system adopts a 3-layer B / S architecture and is divided into a running support platform, a data service platform and a visual display layer from a logical level.

[0030] The visual display layer of the system can display the personnel positioning, the mine site condition and the emergency rescue condition of the open-pit mine;

[0031] The data service layer includes system data, positioning algorithms and directional distribution;

[0032] The running support platform includes intelligent safety helmet terminals, servers, networks and cloud databases;
