Multifunctional intranet and extranet switcher

Abstract

The invention relates to a multifunctional intranet and extranet switcher. The switcher comprises a working mainboard, a single chip microcomputer, an intranet USB port, an extranet USB port , a mechanical switch key, an intranet network port and an extranet network port, wherein the single chip microcomputer, the intranet USB port and the extranet USB port are arranged on the working mainboard. The mechanical switch controls switching of on-off states of the intranet network port and the extranet network port; the working mainboard is further provided with an electronic switch connected with the single chip microcomputer, and the electronic switch controls and switches on-off states of the intranet USB port and the extranet USB port. According to the invention, the switching between the intranet and the extranet is realized through the mechanical key switch, the manual plugging switching mode is replaced, the efficiency is improved, the stability of the system is improved, the USB port peripheral on the intranet or the extranet can be controlled by only one set of shared keyboard and mouse peripheral, the switching between the intranet and the extranet is completed by adopting the mechanical key switch, the intranet and the extranet are not shared by physical circuits and are completely isolated, so that the safety is better.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a multi-function switcher for internal and external networks. Background technique [0002] In order to increase the security of the network usage environment, enterprises or universities will adopt a combined system of intranet and extranet, and each network will be equipped with independent computers and peripherals such as USB keyboard and mouse. Therefore, the extranet system requires two sets of networks and two Set of USB peripherals; due to the physical isolation between the internal network and the external network, when the same set of USB keyboard and mouse peripherals are needed, the connection between the internal and external networks can only be achieved by manually plugging and unplugging network cables and a large number of USB peripheral connection cables. Switching, this method will consume a lot of labor. [0003] There are also internal and external net...

[0002] In order to increase the security of the network usage environment, enterprises or universities will adopt a combined system of intranet and extranet, and each network will be equipped with independent computers and peripherals such as USB keyboard and mouse. Therefore, the extranet system requires two sets of networks and two Set of USB peripherals; due to the physical isolation between the internal network and the external network, when the same set of USB keyboard and mouse peripherals are needed, the connection between the internal and external networks can only be achieved by manually plugging and unplugging network cables and a large number of USB peripheral connection cables. Switching, this method will consume a lot of labor

[0003] There are also internal and external network switches on the market, but the existing internal and external network switches are all completed by switching the drive circuit. There is electronic circuit sharing between the internal and external networks, and the safety performance is not high.
