Abstract

The invention discloses a user-defined protocol analysis device and system for USB (universal serial bus) communication and an operation method of the user-defined protocol analysis device and system. Effective user-defined protocol content is extracted from a universal bus protocol on a hardware level, and the user-defined protocol content is analyzed in combination with a decrypted user-defined protocol configuration file on a software level; the data encryption and decryption module encrypts data in an asymmetric encryption mode, the requirement for high confidentiality of a user-defined protocol is met, the wireless communication module remotely and wirelessly transmits a user-defined configuration file, and the user-defined protocol analysis system remotely sets and operates a mobile terminal on an engineering site. Meanwhile, the abnormal condition of the custom protocol content is detected in real time, so that when the custom protocol content is abnormal, the custom protocol content before the abnormality is transmitted back, and the abnormality of the custom protocol content within the preset time period before the abnormality is analyzed. The flexibility and accuracy of protocol analysis are greatly improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a custom protocol analysis device, system and operation method for USB communication. Background technique [0002] Universal Serial Bus (USB) is a serial bus, which has the advantages of hot plug support, high transmission rate, easy expansion and flexible use, and is widely used in PCs, mobile devices and embedded In commonly used electronic devices such as IOT. The serial bus uses Non Return to Zero Invert (NRZI) differential signals for data transmission. Usually, the USB bus in the above-mentioned electronic devices will package the valid data into a data packet with a private protocol based on the USB protocol, and the complexity of the private protocol is different, and the content of the protocol is also different. At present, the existing protocol analysis equipment mainly analyzes fixed and common protocols, which has the problem of poor flexibility and cannot ...
