A time-sharing transmission method for mass data communication

The invention discloses a time-sharing transmission method for mass data communication, which comprises the following steps: data information transmission between an application layer and a bus layeris realized through a transmission layer including a slicing sub-layer, a planning sub-layer and an asynchronous splicing function; when the application layer is used as the data sender, the address of the target board is determined according to the target interface of the application program in the application layer through the planning sub-layer, and then the data information is divided into pieces through the chip sub-layer, and the piece information is transmitted to the target board through the BIU in the bus layer. When the bus layer is used as the data sender, the slicing sublayer obtains the slicing information from the BIU, then composes the slices, determines the corresponding application program target interface through the planning sublayer, and then composes the slices received many times through the
