Data processing method, device, equipment, data reading end and system

The invention discloses a data processing method, device and equipment, and a data reading end and system. The data processing method comprises the following steps: monitoring real-time bandwidths of a plurality of transmission interfaces; determining a target transmission interface according to the real-time bandwidths of the plurality of transmission interfaces; and transmitting the data of the function daughter card to a data reading end through the DMA channel of the target transmission interface based on a protocol packet in a set format. According to the technical scheme, the data of the function daughter card is dynamically bound to the DMA channels corresponding to the transmission interfaces for transmission according to the real-time bandwidths of the transmission interfaces, the transmission bandwidth is improved, the set protocol packet format is followed, a data reading end can correspondingly process the data transmitted by the DMA channels of the transmission interfaces, and the data transmissi
