The invention discloses a bullet train network equipment safety access system and method. The bullet train network equipment safety access system comprises a bullet train network control system, a plurality of bullet train subsystems connected with the bullet train network control system, a wireless transmission device connected with the bullet train network control system, and a ground server, wherein the wireless transmission device sends the bullet train state, fault and other data received by the bullet train network control system to the ground server in a wireless mode, and the ground server sends a control instruction to the bullet train network control system through the wireless transmission device. The bullet train network equipment safety access method includes the steps: the vehicle-mounted network equipment, including the bullet train subsystems and the wireless transmission device, sends a life signal to the bullet train network control system, and when it is monitored that the life signal of ce
