Problems solved by technology

[0006] The combined use of multiple devices is inconvenient in terms of function and application, and it is not coordinated with each other. The connection is messy, takes up space, and is easy to become a new point of failure.
The main and standby machine management equipment is poor in intelligence, poor in specificity, and cannot be linked; the switching of computer-operated equipment must be manually operated on multiple devices, and cannot be switched automatically; the extension function is unstable, and the extension distance is limited, which cannot meet the requirements

specific Embodiment

[0024] Such as figure 1 As shown, taking dual-screen display as an example (one computer with two monitors), the system consists of a sending end and a receiving end. The sending end device interface includes: keyboard, mouse, audio, DVI, monitor, serial port, etc. Other I / O interfaces can be added. The two-machine arbitration unit receives the heartbeat information of the computer through the serial port, judges the state of the two-machine, determines the master-standby relationship, and sends it to the computer through the serial port. When the main machine and the standby machine are switched, the receiver device will automatically switch to the main machine. Keyboard, mouse, audio, DVI signals, etc. are decoded and converted, and sent to the receiving end through optical fiber.

[0025] Receiver device interfaces include: keyboard, mouse, audio, DVI, serial port, etc. After conversion and decoding, the keyboard, mouse, audio, DVI, serial port signals, etc. are restored...

Abstract

The invention discloses double-machine switch extending equipment, comprising transmitting-end equipment and receiving-end equipment, wherein the transmitting-end equipment is connected with two computers respectively; the transmitting-end equipment is provided with a double-machine arbitration unit, an encoding / decoding unit and the like; and the transmitting-end equipment is connected with the receiving-end equipment by an optical fiber. The transmitting ends of externally extending equipment of the computers and double-machine hot-spare arbitration equipment are combined into the transmitting ends of the double-machine switch extending equipment; the receiving-end equipment is extended by the digital encoding / decoding and optical fiber, so that the whole equipment has the functions of the extending equipment and the arbitration equipment, the extension of the double-machine hot-spare arbitration equipment and the external equipment can be realized, and simultaneously, the conditions of installation, use and maintenance are improved.

Description

technical field [0001] The invention relates to a device for realizing mutual switching between dual hosts, and in particular to an extension device for switching between dual hosts. Background technique [0002] The computer system used for the safe production of railway transportation must have the working ability of 7×24 hours of uninterrupted operation. In order to ensure the high reliability and safety of the system, the form of dual hosts and mutual backup is often used in technology. There are two sets of main machines with the same function running at the same time, one is the main machine and the other is the backup machine. When the main machine breaks down and cannot operate normally, the standby machine is required to automatically switch to the main machine, continue to run, and give an alarm at the same time. When the main machine and the standby machine are switched, the operating equipment should be switched at the same time, so that the user can operate the...
