The invention discloses an intersection signal coordination control system based on wireless signal transmission and GPS timing, and particularly relates to the technical field of traffic signal control, which comprises a signal center control platform, a subsystem platform, a signal lamp group and neurons, a plurality of subsystem platforms are arranged below the signal center control platform, each subsystem platform corresponds to one single intersection, and neurons with the number corresponding to the number of the signal lamp groups are arranged below each single intersection; and the neuron comprises a single-chip microcomputer main control board, a control board, a GPS clock calibration module, a signal state detection module and an NB-IOT signal receiving/sending module. According to the intersection signal coordination control system based on wireless signal transmission and GPS timing, wired transmission is replaced by wireless signal transmission, the use of optical cables and network cables is effectively reduced, the number of data communication times can be reduced as much as possible, the communication pressure can be reduced, and the possibility of communication key leakage can be reduced.
