Power system 101 and 104 communication protocol processing system and processing method thereof

Abstract

The invention relates to a power system 101 and 104 communication protocol processing system and a processing method thereof. The processing system comprises an interface layer, a kernel layer, a datalayer and an application layer. The interface layer is used for receiving the data packet of the external physical communication interface and correspondingly returning a response data packet according to the requirement group of the protocol format. The kernel layer is used for performing function body encapsulation of a unified interface on the content domains with the same data format in the 101 and 104 communication protocols. The data layer is used for transmission of an external data source, logic output control and support of parameters required by other layers. The application layer is used for analyzing and packaging the protocol content and carrying out state flow control according to a response mechanism of the protocol. The specific communication port type used by the protocolis not limited any more, external calling only pays attention to some specific interface functions, protocol processing kernel layer logic implementation is not involved, a protocol library is easy to construct, and the protocol library is convenient to transplant and expand to other single-chip microcomputer application systems for use.

Description

technical field

[0001] The present invention relates to the technical field of data communication process between a master station and a terminal in distribution network and industrial automation applications, and specifically relates to a communication protocol processing system and processing method for power systems 101 and 104 . Background technique

[0002] At present, with the rapid development of computer technology and communication technology, the requirements for the number of data collection of power equipment terminals, the types of transmission physical communication interfaces, and the diversity of protocol transmission channels are becoming more and more important.

[0003] Based on the existing power distribution automation terminal equipment and the main station to communicate with the 101 and 104 protocols, there are the following disadvantages: 1. A certain physical communication interface uses a fixed protocol, such as the conventional serial port or GPRS ...
