Single motherboard dual independent safety computer system

Abstract

The present invention relates to the technical field of computer, specifically to a single motherboard dual independent safety computer system. The system comprises a first hardware system and a second hardware system respectively having a CPU and a power module; the two hardware systems control and share a man-machine interaction interface like a display, a keyboard and a mouse by an intelligentswitching module; the intelligent switching module comprises a general control single chip circuit for receiving and processing external button signals and a sharing switching control single chip circuit; the circuit cooperates with the general control single chip circuit and the two hardware systems to form a set of whole safety computer system circuit with double systems and running independently. Two sets of independent computer hardware system and control circuits are disposed on a PCB board; the double systems can work synchronously or separately, and the systems can be used in two mutually independent network systems; the shared accessories use hardware isolation technology, the safety performance is high; the double systems can be stopped or reset independently; computer does not need to restart or shut off during the switching procedure, and the current operation is not interrupted; the use is convenient.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a computer realization technology for a single motherboard and dual systems. Background technique [0002] In the past, the single motherboard dual system technology of the computer was to set up two system partitions or install two system hard disks on a single hard disk. When the computer was started, it was necessary to manually select the system to be started, and the two systems could only work in time. With the development of technology, it is possible to set two CPUs on one computer at the same time, so that two systems can be installed separately, but it is still necessary to manually select the system to be started when the computer is started, and the two systems can only work in time-sharing , The computer needs to be restarted when the two systems are switched, which is inconvenient to operate. To a certain extent, this loses the meaning of dual systems, and the se...

Problems solved by technology

[0002] In the past, the single motherboard dual system technology of the computer was to set up two system partitions or install two system hard disks on a single hard disk. When the computer was started, it was necessary to manually select the system to be started, and the two systems could only work in a time-sharing manner.

With the development of technology, it is possible to set two CPUs on one computer at the same time, so that two systems can be installed separately, but it is still necessary to manually select the system to be started when the computer is started, and the two systems can only work in time-sharing , the computer needs to be restarted when switching between the two systems, which is inconvenient to operate

To a certain extent, this loses the meaning of dual systems, and the settings of two CPUs cannot be fully utilized, resulting in waste of resources
