Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] figure 1 An exemplary flow chart of a failover method based on the ARINC659 protocol provided by an embodiment of the present invention is shown, as shown in figure 1 As shown, the method mainly includes the following steps:

[0037] Step 101, receiving health status information, and generating a system normal signal through combinational logic;

[0038] Step 102, sending the system normal signal to the ARINC659 bus, so that the ARINC659 bus can send ...

Abstract

The invention belongs to the technical field of computing-electrical digital data processing, and in particular relates to a failover method based on the ARINC659 protocol and a system thereof, the method comprising: receiving health status information, generating a system normal signal through combinational logic; The normal signal is sent to the ARINC659 bus, so that the ARINC659 bus can send and receive data within the set time. ARINC659 bus protocol is used to realize the failover function of the active and standby modules in the computer which are mutually redundant. It makes up for the defect that in the ARINC659 bus protocol, the failure of the main module CPU caused by the inability to monitor the CPU state cannot fail over.

Description

technical field [0001] The invention belongs to the technical field of computing-electrical digital data processing, and in particular relates to a failover method and system based on the ARINC659 protocol. Background technique [0002] The ARINC659 bus is a redundant bus, and the rest of the switching mechanism is at the electrical layer: when using the command table to transmit data, the master module and the standby module will continuously detect the bus activity during the data communication process. In the current window, the standby module waits for the device If it is found that the main module fails to send data normally due to some kind of failure within a certain period of time, the standby module will switch to the main channel to realize data transmission. [0003] The fault isolation of this mechanism stays at the bus communication level, that is, the faults on the bus protocol chip, the bus transceiver and the bus line can be effectively isolated, but the uppe...
