The millimeter wave ad hoc network system according to claim 1, wherein: the terminal equipment (1) is provided with a preparation processor, and when the processing server (3) cannot be accessed, the terminal equipment (1) searches other terminal equipment (1) to process information by the preparation processor and directly feed back the information to the terminal equipment (1) to form a network.
7. The millimeter wave ad hoc network system according to claim 1, wherein: the signal compensation unit (5) at the primary node (21) sends a first calibration packet to the secondary node (22), the secondary node (22) returns the first calibration packet to the primary node (21) and simultaneously sends a second calibration packet to the primary node (21), the signal compensation unit (5) at the primary node (21) obtains the forward attenuation characteristic from the primary node (21) to the secondary node (22) through the difference value of the returned first calibration packet data and the second calibration packet data, the signal compensation unit (5) at the primary node (21) obtains the reverse attenuation characteristic from the secondary node (22) to the primary node (21) through the difference value of the original data of the first calibration packet and the second calibration packet data, and when the information packet is transmitted, the forward attenuation characteristic is transmitted to the secondary node (22) along with the information packet, and the forward attenuation characteristic is continuously transmitted after being calculated by the signal compensation unit (5) of the secondary node (22); when a packet sent by a secondary node (22) is received, the reverse attenuation characteristic is compensated into the packet and the transmission is continued.
8. The millimeter wave ad hoc network system according to claim 7, wherein: the initial data of the first calibration packet and the initial data of the second calibration packet are the same.
