Abstract

The double net electric switcher comprises a plurality of user ports, two groups of network ports corresponding to the switcher, and a group of relay changeover switch. The user port line is connected with the corresponding relay changeover switch jumper end, the two corresponding groups of the network ports connect the two groups of output ends of the relay changeover switch separately, the control coil of which is connected with the changeover switch line of the user port, and the user terminal is connected with the switcher with a connecting line with a changeover switch. A group of the network ports of the switcher are connected with the inner network, while the other network ports are connected with the outer network. The connection and disjunction of the changeover switch determines with which group of network ports the relay changeover switch jumper end is connected, letting the users choose the inner network or the outer network. The switcher realizes the reliable switching and safe physical isolation of the double network, with no need to additionally arrange hardwares such as an isolating card, etc. Only a network line is required to be connected on the user terminal, with low wire laying cost, appropriate to the current existing network wiring, and to the local area network with a plurality of user terminals. And the operation is convenient.

Description

Two net electronic switch

(1) technical field

The utility model relates to a kind of two kinds of mutual device for switching of network, specifically a kind of pair of net electronic switch.

(2) technical background

Along with constantly improving and development of computer networking technology, many units have set up the local area network (LAN) of own inside, and the Internet has also extensively applied to all trades and professions of society.The safety issue of network has caused some important departments of people's great attention, particularly national government, and it is particularly important that internet security seems.Utilize technology such as fire compartment wall, acting server, intrusion detection to resist illegal invasion at present from hacker, virus etc. on the Internet.But constantly the fire compartment wall of upgrading still is that impotentia is resisted state-of-the art virus.High-caliber hacker also may break through fire compartment wall and enter local area network (LAN), steals or destroy important data and resource in this net, and serious meeting causes the collapse of losing of capsule information or system.

In order to guarantee network security, each terminal of local area network (LAN) of now many units does not allow to insert the Internet, has caused the inconvenience of communication and work again.

In order to allow the terminal use can use in-house network and the Internet simultaneously, require network to switch back internal lan and the Internet isolation, promptly there is not physical path between local area network (LAN) and the Internet, could the real safety that guarantees network.

Existing switching isolation technology is to install isolation card additional and use two hard disks in subscriber computer, switches and isolates different networks and select different hard disks with isolation card.Install isolation card additional and need take computer apart, very inconvenient, and also can't install additional for the limited notebook computer in space in the machine.Isolation card is difficult to use part to be, is to finish on the isolation card of subscriber computer owing to switch, so the line of two networks all need be received on the user terminal.This improves the networking cost.Particularly the finishing of present many office spaces has only been pre-installed single cover grid line, and the rewiring difficulty is bigger.

(3) utility model content

The purpose of this utility model is a kind of pair of net electronic switch of design, and through special user terminal network line, this switch is finished two switchings of netting at a distance, and accomplishes physical isolation.

Two net electronic switch of the utility model design, comprise cabinet housing, a 4-24 user port, two groups and the user port network port, power interface and mains switch one to one, also be furnished with and a user port group relay change over switch one to one, each relay change over switch has a plurality of synchronous jumper switchs, and the wire jumper end of the input-output line of user port and corresponding with it relay change over switch is connected; Two corresponding group network ports connect two groups of outputs of this relay change over switch respectively, and the control coil of this relay then is connected with the diverter switch line of this user port, and diverter switch is positioned on the line that connects this user terminal and this switch.

User terminal is connected with this pair net electronic switch with the special line that has diverter switch, the hub of network switch or Intranet in one group network port of this pair of net electronic switch connects, another group network port then connects the hub of outer network switch or outer net.The action of the break-make of diverter switch decision relay change over switch, determine its wire jumper end to be connected with the network port of which group, thus realization user terminal selecting use Intranet or outer net.

When being connected with certain network port, disconnect, guarantee that the user can only keep being communicated with a network, has just guaranteed the physical isolation of intranet and extranet with the port of another network because of the wire jumper end of relay change over switch.This pair of net electronic switch adopts hardware mode to realize the switching and the physical isolation of two nets, provides highly reliable a, low cost solution for intranet and extranet switch to isolate, and has made things convenient for when guaranteeing the Intranet information security and being connected of Internet.

This electronic switch can be suitable for the various subscriber computers that network interface is arranged, and user's type is not had specific (special) requirements, also need not to install additional the hardware of isolation card and so on.User terminal only need connect a network connectivity, and network wiring cost is low, is fit to present existing network line and uses.This switch has a plurality of user ports, is applicable in the local area network (LAN) of a plurality of user terminals.

This electronic switch is easy to operate, and the user only need press the diverter switch on the network connectivity, promptly remote controlled the relay change over switch action that two net electronic switch are interior.The user need not restarting systems, selects network configuration can realize the seamless switching of intranet and extranet by the software on this machine, and the legacy network performance is had no effect.

The employed relay change over switch of this electronic switch long service life, conversion have reliably guaranteed the working life and the reliability of this switch.

The described user port and the network port are general RJ45 port, and each relay change over switch has 4 synchronous jumper switchs, and the wire jumper end of two pairs of input-output lines of each user port and corresponding relay change over switch is connected; The network port of two groups of correspondences connects 4 outputs of two groups of this relay change over switch respectively.

For the ease of user's operation, described diverter switch is positioned on the line that connects user terminal and this switch, close user terminal place.

For ease of connecting and observing each port working state, the user port of this pair net electronic switch and two group network ports all are positioned on the casing front panel, and each port is other this port running LED, with the network of indicating each port-select to select.
