Unidirectional physical isolation data transmission method and device

The invention provides a unidirectional physical isolation data transmission method and device, and the method specifically comprises the steps that first network equipment transmits original data tolight splitting equipment when the first network equipment needs to transmit the original data to third network equipment; and the light splitting equipment receives the original data, splits the original data according to a preset proportion to obtain corresponding first data and second data, sends the second data to a second network equipment, and sends the first data to third network equipment.According to the invention, the second data can be verified based on the communication between the first network equipment and the second network equipment, the data integrity is confirmed, the transmission efficiency is improved, and the resource consumption is reduced. 本申请提供一种单向物理隔离的数据传输方法与设备，具体包括：所述第一网络设备在需要向所述第三网络设备发送原始数据时，向所述分光设备发送所述原始数据；所述分光设备接收所述原始数据，按照预设比例对所述原始数据分光，得到对应的第一数据和第二数据，并将所述第二数据发送给第二网络设备，将所述第一数据发送给所述第三网络
