The invention discloses an intelligent transformer substation process level message linear processing framework, which comprises a network processor, a data packet input processing unit and a random storage which are connected with each other. The data packet input processing unit is a hardware co-processing unit and is provided with a network message interface and used for receiving and distributing network message, directly accesses the space of the random storage and simultaneously sends accident information to the network processor. The invention further provides an intelligent transformer substation process level message linear processing method. The intelligent transformer substation process level message linear processing framework is simple, clear in module, strong in expanding performance and suitable for receiving and processing a large amount of network data information of an intelligent transformer substation, removes the message processing bottleneck in the original method, and leads operation of the intelligent transformer substation to be safer and more reliable. The intelligent transformer substation process level message linear processing method can conduct linear receiving and processing on message of the intelligent transformer substation under the premise without processor response interrupting, and solves the bottleneck problems in central processing unit (CPU) data packet receiving and processing caused by high-frequency interruption.
