The invention relates to a device used for configuration and testing of a FlexRay network and belongs to the communication technical field. The device comprises a power unit, a FlexRay communication device, a programmable logic device, a USB (Universal Serial Bus) communication device, a memory DRAM (Dynamic Random Access Memory) and an upper computer. The device solves the problems that the existing integrated FlexRay testing device only obtains the communication data and is inflexible; through the device, the data testing of a FlexRay bus is realized, the network operation parameters, the operating state and an interval between measurement data frames can be obtained while the on-line configuration of the network parameters can be carried out conveniently, and the device can help an engineer to design the FlexRay network more quickly and optimally.
Description
technical field [0001] The invention relates to a configuration and testing device for a FlexRay network, which belongs to the technical field of communication. Background technique [0002] As a next-generation vehicle network, FlexRay has been widely used due to its high bandwidth, dual-channel redundancy, and deterministic message sending time. At the same time, there are some related test devices on the market, such as Vector's VN7600, one end can be connected to the FlexRay network, and the other end can be connected to the host computer through USB, and the data on the network can be uploaded to the host computer for analysis. [0003] However, these commercial test devices, because they are integrated by suppliers, can only obtain communication data, and cannot perform further network performance analysis, such as network operating parameters, and the status of whether the receiver in the network has correctly received the data. information, and cannot solve the prob...
