Communication system serving underground

The invention discloses a communication system serving underground, relates to the technical field of communication, and solves the problem that in the prior art, underground air quality is not monitored in real time, so that underground workers cannot be rescued in time when danger occurs. The method comprises the following steps: a data processing module performs comparative analysis on air quality information and vital sign information sent by an intelligent terminal module and a standard range of the air quality information and the vital sign information, and performs classified packaging on the information; the data transmission module processes the signals sent by the data processing module, reasonably distributes the signals to different transmission channels and transmits the signals to the ground receiving module; the ground receiving module processes the primary early warning signal in time and predicts temperature quality information at the next moment; the underground air quality and personnel vit
