Rail transit multi-train energy-saving coordinated communication system

The invention relates to a rail transit multi-train energy-saving coordinated communication system. The system comprises an energy-saving server cluster, a data domain and an ATS, the data domain is in communication connection with the energy-saving server cluster so as to transmit distributed parallel computing data and an energy-saving coordination computing result of the energy-saving server cluster to the data domain, and meanwhile, the energy-saving server cluster receives data from the data domain; the data domain is further in communication connection with the ATS and then is in communication connection with the plurality of CBTC links correspondingly, so that the energy-saving coordination calculation result is transmitted to the CBTC links correspondingly through the ATS, and meanwhile, the existing CBTC data and a scheduling command from the ATS are received through the ATS; the energy-saving server cluster is further in communication connection with the ATS so as to receivetrain working diagram dat
