Arbitration device for double computer redundancy hot backup computer

Abstract

The invention discloses an arbitration device for a double computer redundancy hot backup computer. The arbitration device for the double computer redundancy hot backup computer comprises an arbitration controller (7), a state control monitor (5) and a network switcher (8), and further comprises a milestone information synchronizer (6), an IO switching module (10), an RS422 switching module (11), a KVM switching controller (9), a work host computer dual port RAM interface (3) and a backup host computer dual port RAM interface. In the initial phase of booting the double computer redundancy hot backup computer, the arbitration device firstly confirms a host computer on duty between a work host computer and a backup host computer, and secondly performs booting synchronization. In the running process after booting the double computer redundancy hot backup computer, the arbitration device firstly performs task synchronization and data synchronization on the work host computer and the backup host computer, and secondly performs switching operation so as to obtain a work shift between the work host computer and the backup host computer. The arbitration device for the double computer redundancy hot backup computer meets the requirements of a display and control platform of a modern naval ship auxiliary device for manipulation ability and timeliness of the double computer redundancy hot backup computer.

Description

[0001] technical field [0002] The invention relates to an arbitration device, in particular to an arbitration device for dual-machine redundant hot backup computers. Background technique [0003] The arbitration device is the core device of the dual-machine redundant hot backup computer, which monitors and synchronizes the status of the two hot backup hosts, selects the on-duty host according to the status information, and switches the external input and output signals between the working host and the backup host . At present, there are many kinds of commercial redundant computers in the domestic and foreign markets. The arbitration device is integrated on the computer motherboard, including: arbitration controller, network switcher, USB switcher, status monitor, working host status monitoring interface and backup Host status monitoring interface, wherein the working host status monitoring interface is connected to the status monitor, the backup host status monitoring int...
