Embodiment 1

[0075] see figure 1 , a computer integrated system, including a dual power supply system, the dual power supply system is linked with the cache system, the cache system is linked with a control module and a backup module, and the control module and the backup module are also linked with each other, and the control module includes a base The computing module, the information processing module and the storage module, the backup module includes cache data backup and long-term data backup, the control module and the backup module are connected with the monitoring module, and the monitoring module is also connected to the dual power supply system.

[0076] The dual power supply system includes a master CPU and a slave CPU. The master CPU and the slave CPU respectively include a master CPU control module and a slave CPU control module. The master CPU and the slave CPU are connected to each other. A status module, a voltage and current detection module, a drive module and a communica...

Embodiment 2

[0080] see Figure 2-4 , based on Embodiment 1, the difference is that;

[0081] A method for automatic failover, which is applied to a computer integrated system, comprising the following steps:

[0082] S1, supplying power to the computer integrated system, making the main power supply module of the dual power supply system work, and powering on the main CPU and the slave CPU;

[0083] S2. The main CPU and the slave CPU work to collect data on the current and voltage of the power supply and the current and voltage fed back by the computer integrated system;

[0084] S3, processing and analyzing the data collected in S2, and then substituting the sorted data into the calculation method of power failure detection, and judging whether there is a failure according to the calculation result;

[0085] S4, if the power failure detection calculation result shows that there is no fault, then directly return to the instruction, re-do the data acquisition and power failure detection ...

Embodiment 3

[0100] The difference based on embodiment 1 or 2 is that;

[0101] A computer power failure detection algorithm is mentioned in S3, the specific content is:

[0102] Set the grid phase voltage:

[0103]

[0104] Its differential is:

[0105]

[0106] Assuming that the number of sampling points is N in a power frequency cycle, and the time interval between two adjacent sampling points is t, then the voltage of the kth sampling point is:

[0107]

[0108] The k-1th sampling point voltage is:

[0109]

[0110] Use difference instead of differentiation:

[0111]

[0112] When the sampling interval t is relatively small:

Abstract

The invention discloses a computer integrated system and an automatic fault switching method, and belongs to the technical field of computer systems. The computer integrated system provided by the invention comprises a dual-power supply system, a cache system, a backup module and a monitoring module, so that the use fluency and safety of a computer system are greatly improved. According to the automatic fault switching method provided by the invention, the master CPU and the slave CPU are arranged to cooperatively manage the power supply module, so that the safety is higher, and the reaction speed is higher. By means of the design, the problems that an existing computer and an existing computer system can be suddenly shut down when encountering a power failure and cannot be continuously used, work and life are affected, and the computer is damaged are effectively solved.

Description

technical field [0001] The invention relates to the technical field of computer systems, in particular to a computer integrated system and a fault automatic switching method. Background technique [0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logic calculations, and storage and memory functions. It is a modern intelligent electronic device that can run according to programs and process massive amounts of data automatically and at high speed. equipment. [0003] A computer is mainly composed of a hardware system and a software system. A computer without any software installed is called a bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. More advanced computers include biological computers, photonic computers, quantum computers, etc. With the development of ...
