Abstract

The invention provides a communication data processing method and device, which are applied to communication data processing equipment. The equipment comprises an Ethernet protocol stack device, the Ethernet protocol stack device is connected with a CPU, the Ethernet protocol stack device comprises a software protocol channel for transmitting non-real-time data and a hardware protocol channel for transmitting real-time data; the hardware protocol channel comprises a hardware protocol stack for processing real-time data, and the CPU is provided with a software protocol stack for processing non-real-time data; through data distribution, real-time data transmission passes through a hardware protocol stack channel, non-real-time data transmission passes through a software protocol stack channel, the load of a CPU can be reduced, meanwhile, the efficiency of a hardware protocol stack is improved, and it is guaranteed that real-time data generates minimum time delay; in addition, high-precision clock synchronization can be adopted in a system where the equipment is located, it is guaranteed that real-time data frames are reliably transmitted within a certain precision, scheduling management of the whole system is conducted on data based on a scheduling table, and it is guaranteed that communication conflicts do not occur.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication data processing method and device. Background technique [0002] With the development of science and technology, various types of transportation have been equipped with communication networks, such as trains. The communication network of trains is known as the "brain" and nerves of trains. It is mainly used for control data, monitoring data, The transmission of train communication data such as fault data, maintenance data and service data is an important system to ensure train safety and improve rail transit service quality. With the popularization of Ethernet technology, the network control system based on Ethernet technology has become a train communication network development trend. [0003] In the existing Ethernet technology-based train communication network, the train communication data is often processed and transmitted through the central pr...
