Abstract

The invention relates to a dual-redundancy USB port expansion device capable of monitoring in real time, and belongs to the technical field of military ruggedized computers. According to the invention, real-time monitoring of the working state of a USB expansion port is realized by designing a dual-redundancy USB port thought; when a USB port is abnormal in communication, equipment connected withthe USB port can be powered off and restarted on line, and the function of automatically switching to a standby USB port is achieved. The working requirements of USB equipment such as a USB keyboard module, a USB mouse module, a USB voice module, a USB control module, a USB key module and the like of a display control computer and a finger control computer under war preparedness or battle conditions are met; the problems that the USB equipment can be powered off again after being disassembled when communication is abnormal and can continue to work after faults are removed are solved, and the reliability and practicability of a display control computer and a command control computer are improved.

Description

technical field [0001] The invention belongs to the technical field of military reinforcement computers, in particular to a dual-redundant USB port expansion device that can be monitored in real time. Background technique [0002] The USB port expansion device is an important part of the display and control computer and the commanding computer. The display control computer and the commanding computer are installed on the display console and the data processing cabinet, and are used to display the software interface to provide human-computer interaction information and provide a data processing and computing platform for the commanding system. On the display console and data processing cabinet, multiple USB ports are required to connect the USB keyboard module, USB mouse module, USB voice module, USB control module and USB key module, etc. These USB devices are usually connected by fastening devices. It is installed on the display console and data processing cabinet, and can...
