Abstract

The invention discloses a protocol message detection method, a protocol message detection device and electronic equipment. The method comprises the following steps: acquiring a key field of at least one message segment in a protocol message; matching the key field in the at least one message segment with a standard key field in a plurality of standard message segments to obtain a target standard message segment; matching the at least one message segment with a target standard message segment to obtain a matching result corresponding to the at least one message segment; and outputting a detection result of the protocol message according to the matching result corresponding to the at least one message segment. According to the invention, the technical problem of low detection efficiency of the protocol message in the prior art is solved.

Description

technical field [0001] The invention relates to the field of protocol messages, in particular to a method for detecting protocol messages, a device thereof and electronic equipment. Background technique [0002] At present, the protocol detection of the Beijing rail transit video surveillance system adopts the method of software capture and manual analysis of the content of the capture, which mainly has the following disadvantages: [0003] The detection efficiency is low and the detection cycle is long. It is necessary to manually verify all protocol packet information word by word, and the detection efficiency is low. [0004] The detection accuracy is not high, and the phenomenon of missed detection and wrong detection is prone to occur. Manual detection is affected by the inspector's carefulness and business proficiency, and it is prone to missed detection. At the same time, manual detection is difficult to identify information such as spaces and carriage returns in th...
