Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] At present, domestic subway vehicles and high-speed trains cannot achieve transparency during vehicle commissioning. Due to failures in the control network during operation, it is difficult to find the real source of the problem, and its maintenance is very difficult. Therefore, effective detection of MVB network data is an essential means for design, implementation, operation and maintenance, and repair and maintenance of the control system.

[0041] Existing MVB network detection equipment usually adopts a dedicated MVB controller to control the core MVB network. The MVB controller will be connected to the CPU (Central Processing Unit, Central Processing Unit) through the PC104 bus, and the CPU w...

Abstract

The invention provides data detecting equipment and a method for the MVB (multifunctional vehicle bus) network. The data detecting equipment comprises an FPGA (field programmable gate array) controller, a USB (universal serial bus) controller, a USB interface and an MVB physical interface, wherein the FPGA controller is connected with the MVB network through the MVB physical interface, captures data packets transmitted by the MVB network and decodes. If the decoded data of the data packets are complete, the data are transmitted to an upper computer through the USB controller, and on the contrary, the decoded data of the data packets are incomplete, the data are processed by an error analyzing module of the FPGA controller and error information is then sent to the upper computer by the USB controller. The data detecting equipment is capable of realizing real-time process and analysis of the data of the MVB network by the aid of the FPGA controller, is high in data processing efficiency and time-saving. Besides, the data can be transmitted to the upper computer at a high speed through USB serial ports without the data transmission mode controlled by a CPU (central process unit), error information and correct data can be reported quickly.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data detection device and method for an MVB network. Background technique [0002] In June 1999, the TCN (Train Communication Network, Train Communication Network) standard draft IEC61375-1 officially became an international standard. In April 2007, IEC61375-1 was revised and the second edition was released. At the same time, the IEC61375-2 train communication network compatibility test standard was released. This standard divides the communication network into a train-level communication network WTB (Twisted Train Bus, twisted train bus) for connecting vehicles that can be dynamically organized in each section and a vehicle communication network MVB (Multifunctional Vehicle Bus) for connecting fixed equipment in vehicles. , multifunctional train bus). [0003] Among the current domestic CRH (China Railways High-speed, China High-speed Railway) series EMU...
