Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The embodiment of the present invention is the programming technology of multiple communication protocol detection methods, and multiple communication protocols are received and sent in one communication interface; this embodiment completes the buffering of received data through a cyclic data receiving linked list; in the initial state, receiving The pointer and each protocol pointer point to the same address of the circular receiving buffer. When data is received, the data is stored in the circular receiving buffer, and the receiving pointers are added circularly automatically.

[0019] Such as figure 1 As described, the operation steps of this embodiment are as follows:

[0020] 1. Determine whether the protocol pointer is equal to the receiving pointer;

[0021] 2. If they are equal, it means that there is no received data...

Abstract

The invention relates to the technical field of communication protocols, in particular to a multi-communication protocol detection method. The multi-communication protocol detection method comprises the following steps: when receiving a legal and integral protocol frame, checking the format of the protocol frame, and calling a corresponding protocol processing service according to the format of the protocol frame to carry out protocol processing. According to the invention, the receive data is cached through a loop data receiving linked list; and the judgment and processing of every communication protocol frame is completed according to the relation between multiple communication protocol pointers and receiving pointers without mutual influence.

Description

technical field [0001] The invention relates to the technical field of communication protocols, in particular to a multi-communication protocol detection method. Background technique [0002] In the current multi-protocol system, each communication protocol has an independent receiving buffer, and independently determines each communication protocol; [0003] Most of the data reception is completed in the interrupt service program. If multiple protocol receive buffers need to process received data, the interrupt service time will be extended, and each protocol requires a receive data buffer, which will occupy a large amount of RAM area resources. Contents of the invention [0004] The invention provides a multi-communication protocol detection method to solve the technical problem that the prior art cannot uniformly process multiple communication protocols. [0005] In order to realize the purpose of the invention of the present invention, the technical scheme adopted is ...
