Abstract

The invention discloses a computer-controlled double-computer hot redundancy system. The computer-controlled double-computer hot redundancy system includes a main control computer, a hot standby computer, a keyboard, a display, a mouse, a keyboard display, and a mouse switcher, wherein the main control computer is responsible for the test and task control of the current system; when the main control computer works normally, the hot standby computer is responsible for tracking the progress of the current control task and monitoring the working condition of the main control computer; the keyboard, the display and the mouse are used for input, output and display of the main control and hot standby computers; the keyboard display and the mouse switcher KVM can complete switching of the keyboard, the display and the mouse in the main control and hot standby computers; a switch signal output port of the main control computer is connected with a switch signal input port of the hot standby computer through a signal line; a power control port of the main control computer and a KVM switching port access the switch signal output port of the hot standby computer; and data ports of the keyboard, the display and the mouse are connected with a data input port of the KVM. The invention also discloses a computer-controlled double-computer hot redundancy method.

Description

Technical field [0001] The invention relates to the field of computer technology. More specifically, it relates to a dual-computer thermal redundancy method for controlling a computer. Background technique [0002] At present, with the application and development of computer technology in the field of measurement and control, computer measurement and control system architecture based on CAN, LAN, MIL-STD-155B and other distributed test and control buses has become the field of computer test and control applications, especially for high reliability A system construction scheme commonly used in the field of application requirements testing and control. For computer measurement and control systems based on distributed test and control buses, especially test and control systems for high reliability application requirements, the task reliability design of the control computer directly affects the reliability index of the entire system. [0003] For the control computer of the distribu...
