Embodiment Construction

[0031] see figure 1 , figure 2 , the switching method of double redundancy computer failure processing of the present invention, comprises the following steps:

[0032] 1) Power on the system, the master device control is prohibited, and the slave device control is prohibited;

[0033] 2) Real-time monitoring of the system status from the device;

[0034] 3) judge whether the master device works normally from the device; if so, the master device controls the output, and the slave device performs backup monitoring; if not, then proceed to step 4);

[0035] see image 3 , the specific steps for the slave device to judge whether the master device is working properly are:

[0036] 3.1) Slave equipment detects main equipment, at first judge whether main equipment power failure, if so, then the failure register of main equipment is put into '0' by '1', if not, then carry out step 3.2);

[0037] 3.2) judge whether master equipment has watchdog to report to the police, if so, th...

Abstract

The invention discloses a switching method for processing a fault of a dual-redundancy computer, which comprises the following steps that: 1, a system is powered up, a master device carries out control inhibition and a slave device carries out control inhibition; 2, the slave device carries out real-time monitoring on the state of the system; 3, the slave device judges whether the master device normally works, if yes, the master device carries out control output and the slave device carries out backup monitoring, and if no, the step 4 is executed; 4, the master equipment notifies the slave equipment fault information; and 5, the master device carries out control inhibition and the slave device implements switching control output and simultaneously monitors the master device. According to the switching method for processing the fault of the dual-redundancy computer, which is disclosed by the invention, the fault logicality is implemented by adopting a discrete magnitude signal and a FPGA (Field Programmable Gate Array), the fault judgment, the fault information transmission and the master and slave function switching of the master and slave devices are completed in real time.

Description

technical field [0001] The invention relates to a computer fault processing method, in particular to a dual redundancy computer fault processing switching method. Background technique [0002] In order to improve the reliability of the system, many computer systems adopt the dual-redundancy hot backup working mode for the entire equipment or some key functions. To ensure that the system continues to work normally, today's embedded computers have strict requirements on reliability, power consumption and size. This method must back up the device, and only after the system fails will the backup device be used to find the fault of the main device and switch , requires a lot of additional resources, consumes a lot of power, and the running process and operation process are quite complicated. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a switching method for dual-redundancy com...
