Dual-computer backup system and backup method

Abstract

The invention discloses a dual-computer backup system and backup method. The dual-computer backup system is characterized by comprising a public module, a first service, a second service, a first control module and a second control module; the disclosure module comprises a switching module and an abnormality detection module, and the abnormality detection module is connected with the switching module through a data bus F; the first service is connected with the switching module through a data bus A and is connected with the anomaly detection module through a data bus C; the second service is connected with the switching module through a data bus B and is connected with the anomaly detection module through a data bus D; the first control module is connected with the first service, the second control module is connected with the second service, and the first service is connected with the second service through a data bus G. By adopting a software and hardware combination mode, the reliability of the system can be remarkably improved, so that the high reliability of each port is realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a dual-machine backup system and a backup method. Background technique [0002] At present, the system generally adopts the design of a single device to provide external ports such as IO / UART / I2C / SPI / LVDS / BT1120, but the design of a single device is simple and cannot guarantee that it can still work normally after the system is abnormal. In special occasions where reliability is required, a single device may cause the port to work abnormally due to some reasons; obviously at this time, a single device cannot meet the high reliability requirements of the system. The above problems urgently need to be resolved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-machine backup system and backup method, which can significantly improve the reliability of the system by adopting the combination of software and ha...

[0002]At present, the system generally adopts the design of a single device to provide external ports such as IO / UART / I2C / SPI / LVDS / BT1120, but the design of a single device is simple, There is no guarantee that the system can still work normally after the system is abnormal. For some special occasions that require high reliability requirements, a single device may cause the port to work abnormally due to some reasons; obviously at this time, a single device cannot meet the high reliability requirements of the system.
