Description

technical field [0001] The invention relates to the technical field of vehicles and railway trains, in particular to a multi-type vehicle bus detector. Background technique [0002] At present, my country's train vehicle communication network bus mainly uses Ethernet, MVB, CAOPEN and other networks. [0003] Among them, the physical layer interface of Ethernet communication meets the requirements of IEEE 802.3, supports 100BASE-TX transmission media, and supports full-duplex communication. terminal with a pin connector. The M12 connector shall have a metal shielding shell. The cables are required to use Category 5e twisted-pair cables that meet the requirements of ISO / IEC 11801 and IEC61156-6 standards. The shielding layer of the Ethernet cable and the shell of the M12 connector should be reliably connected in a 360° ring. The equipment should be equipped with a grounding point to ensure reliable grounding of the equipment. At the same time, the shell of the M12 connector...

AI Technical Summary

Problems solved by technology

[0006] With the development of the railway industry, vehicle buses such as Ethernet, MVB, and CAOPEN have been widely used, but due to the specificity and pertinence of each communication network (mainly used in some special fields such as railways and some power systems) , there are very few industrial field test methods and instruments, especially the lack of a comprehensive test equipment that can target multiple types of vehicle buses

And the existing detection method is to rely on the on-site staff to configure a notebook computer, and connect various types of buses by USB to serial ports to realize the individual detection of each network. This method needs to install drivers on the computer, such as computer failure or If the system is reinstalled, the driver needs to be reinstalled, which is a waste of time

In addition, after separate detection of each communication network, the data on the laptop needs to be uploaded to the host computer for centralized storage, backup, and analysis, and the detection efficiency is low
