Abstract

The application discloses a repeater based on a MVB (Multifunctional Vehicle Bus). The repeater comprises A plurality of MVB connector interfaces and a plurality of data processing units, wherein theplurality of data processing units comprises a first data processing unit for using data transmitted by the plurality of MVB connector interfaces through a first line as an output of the first line after carrying out amplification processing on the data, and a second data processing unit for using data transmitted by the plurality of MVB connector interfaces through a second line as an output of the second line after carrying out amplification processing on the data; the first data processing unit and the second data processing unit respectively correspond to at least one redundant data processing unit; and when first data processing unit and / or the second data processing unit is abnormal, the data output by the first data processing unit and / or the second data processing unit is correctedby the corresponding at least one redundant data processing unit. By the repeater disclosed by the application, the problems that in the related art, a repeater cannot correct a fault bus and a redundancy bus is low in redundancy.

Description

technical field [0001] The present application relates to the technical field of repeaters, in particular, to a repeater based on a multifunctional vehicle bus. Background technique [0002] The Multifunctional Vehicle Bus (MVB for short) bus is a serial data communication bus mainly used (but not exclusively) for interconnected devices requiring interoperability and interchangeability. At present, the MVB repeaters used in vehicles are generally in the form of single-channel independent work. Once a problem occurs in a certain channel, since the repeater does not have the function of copying and correcting the faulty channel, there will be no faults on the bus behind the repeater. Any waveform, this will greatly reduce the redundancy function of the dual bus. Once the MVB interface of the subsequent device corresponding to the normal bus also has problems at this time, it will cause the device to go offline. [0003] Aiming at the problems in the related art that the repea...
