A Communication Method Based on Protocol Configuration

Abstract

The present invention discloses a protocol configuration-based communication method. The method comprises the steps of sending a command configuration message to a device end by a server end, wherein the command configuration message includes a command number, a protocol name, a command attribute, an analysis attribute and a command message; forming a response message and feeding the response message back to the server end by the device end after receiving the command configuration message; assembling the return messages of interaction equipment and sending the assembled data packet to the server end by the device end; parsing the assembled data packet by the server end after receiving the assembled data packet, forming a response message after the completion of the parsing step and feeding the response message back to the device end. According to the technical scheme of the invention, the universality of the server configuration manner is ensured, and the configuration of all types of commands is enabled. Meanwhile, the uniqueness of the underlying equipment firmware is ensured and interfaces are provided for field debugging. The original field data content can be observed and analyzed only through setting the analysis attribute to be direct return. Therefore, the method can be applied to any field based on interactive reading-writing operations.

Description

technical field [0001] The invention belongs to the field of industrial automation and is a communication method, in particular to a communication method based on protocol configuration. Background technique [0002] In the field of industrial automation, due to the different brands and models of instruments / controllers used on site, it is necessary to match different buses or protocols when reading instrument / controller parameters. When traditional instruments / controllers monitor or collect system data, in order to adapt to various types of buses or protocols, different firmware needs to be customized. This situation not only increases the complexity of development and maintenance costs, but also increases the difficulty of field data collectors. Similarly, for other fields outside of industrial automation, there will be a wide variety of communication protocols. [0003] The patent application number is CN201510476097.8 "A data communication method for locomotive display...
