Provided is an underground LED intelligent display management assistance system, which belongs to a display management assistance system. According to the display management assistance system, LED intelligent display terminals are installed in underground personnel-intensive areas and key monitoring areas, and duplex communication is carried out between the LED intelligent display terminals and a ground LED intelligent management service system and other LED intelligent display terminals of all levels in a wired or wireless transmission mode. A sensing information system transmits underground data to the LED intelligent management service system for cluster analysis, a classification result is processed by software, and the processed classification result is transmitted through the Ethernet to the embedded LED intelligent display terminals for displaying all underground information and all ground instructions in real time. The underground LED intelligent display management assistance system has the following advantages: the LED intelligent display terminals are installed underground for displaying monitoring data of various sensors, huge waste of information is prevented, the practicability, visualization, intuitiveness and transparent degree of coal mine monitoring information and management scheduling are improved, underground safety production and efficient management are realized, and the system is simple in operation, high in practicability and convenient in staff scheduling.
