Abstract
The utility model discloses a network switching device. Through a switching switch in a control line control device, a host can be connected with two networks, while cannot be connected with the two networks simultaneously, and therefore, the host can be switched between the two networks freely.
Description
Technical field
The utility model relates to electronic applications, relates in particular to a kind of network switching device.
Background technology
School web laboratory mostly adopts and says that main frame directly connects switch at present, then through router, connect outer net, switching internal lan or exterior I nternet net like this, need manually the network of plug netting twine switch extremely loaded down with trivial details and easily damage interface, operate and not carefully also likely because netting twine pulls out to misplug by mistake, cause circuit to connect fault, bring inconvenience to the switching of network.
Utility model content
Technical problem to be solved in the utility model is for the defect in background technology, and a kind of network switching device that laboratory main frame can freely be switched in two networks is provided.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A network switching device, comprises mains switch, control switch and at least one switch unit, and described switch unit is connected with mains switch by control switch, and described mains switch is connected with external power source.
As the further prioritization scheme of a kind of network switching device of the utility model, described switch unit comprises PC interface, first network interface, second network interface and the diverter switch that PC interface is connected with first network interface or second network interface, and described diverter switch is connected with control switch.
As the further prioritization scheme of a kind of network switching device of the utility model, the number of described switch unit is four.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
Under the prerequisite of motionless main frame behind netting twine, can realize main frame and freely between heterogeneous networks, switch.
Accompanying drawing explanation
Fig. 1 is network switching device structure principle chart;
Fig. 2 is the outside cabinet front view of network switching device.
In figure: 1, shell, 2, mains switch, 3, network 1 interface, 4, control switch, 5, PC interface, 6, network 2 interfaces, 7, diverter switch.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:
Take network 1 interface, PC interface, network 2 interfaces, all to contain four interfaces be example, as shown in Figure 1, mains switch 2 is connected with diverter switch 7 and powers to it, network 1 interface 3 is all connected with diverter switch 7 with network 2 interfaces 6, and diverter switch 7 is also connected with control switch 4, PC interface 5, by control switch 4, controlling diverter switch 7 switches, make 7 of this diverter switches be connected with network 1 interface 3 or only be connected with network 2 interfaces 6, realized thus main frame freely switching in heterogeneous networks.
As shown in Figure 2, whether mains switch 2 is controlled power supply and to device, is powered, control switch 4 is being controlled diverter switch 75, PC interface is connected with network 1 interface 3 or network 2 interfaces 6, network 1 interface 3 connects and on switch, is connected to network 1, network 2 interfaces 6 connect switch and are connected to network 2, and PC interface 5 is used for connecing the main frame in network laboratories.
Claims (3)
1. a network switching device, is characterized in that, comprises mains switch, control switch and at least one switch unit, and described switch unit is connected with mains switch by control switch, and described mains switch is connected with external power source.
