The intelligent switch machine equipment that the utility model is provided is described in further detail below.Wherein, the intelligent switch machine equipment is that example is introduced with the routing device.
In the intelligent switch machine equipment that the utility model provides, when considering network interface card work, the level of the VCC pin of the network interface card interface corresponding with this network interface card is greater than the level of GND pin on the routing device, therefore, can judge whether network interface card works according to the VCC pin of network interface card interface and the voltage difference of GND pin.If all network interface cards of equipment all do not have work, then do not need to be power devices; If arbitrary network interface card work is power devices in the equipment.
Concrete, network interface card serves as physical interface or the line between computer and the network cable (netting twine), converts the digital signal in the computer to electricity or light signal.The transmission of data in computer bus is parallel mode, and promptly data are transmitted shoulder to shoulder, and data are transmitted in the bit stream mode of serial in netting twine, and therefore, network interface card is born the conversion between serial data and parallel data.Network interface card was realized with being connected by Transformer (isolating transformer) of netting twine, the coil that the differential signal that Transformer sends PHY in the network interface card (phy chip) is coupled with differential mode is coupled filtering with enhancing signal, and be coupled to an other end that connects netting twine by the conversion of electromagnetic field, not only making does not have connection physically between netting twine and the PHY and changes and transmitted signal, cut off the DC component in the signal, can also in the equipment of different 0V level, transmit data.Because the signal level that produces during the network interface card operate as normal is always greater than 0V, therefore, when network interface card interface that the other end of netting twine is a routing device, the level of the access voltage VCC pin in this network interface card interface (signal that sends with network interface card is connected) is greater than 0V.Also comprise the GND grounding pin in the network interface card interface, the level of GND pin is 0V.Therefore, when the network interface card operate as normal, the VCC pin in the network interface card interface pair increases with the voltage of GND pin, and the level of VCC pin is greater than the level of GND pin.
In the utility model, the VCC pin and the voltage difference of GND pin that automatic switch detects the network interface card interface are set, and according to testing result on off state are set and are closed or disconnection.This automatic switch specifically comprises circuit chip, VCC pin line and GND pin line, and VCC pin line and GND pin line are connected VCC pin and the GND pin in the network interface card interface of routing device respectively.When routing device has a plurality of network interface card interface, automatic switch connects the VCC pin of each network interface card interface by many VCC pin lines, the GND pin of all network interface card interfaces has identical level, be generally 0V and interconnect, so automatic switch can be by the GND pin in the GND pin connecting diagram card.
Wherein, circuit chip can be according to the closure or the dead circuit chip of the voltage difference control automatic switch of the VCC pin of network interface card and GND pin for OR-NOT circuit chip or other.
Be that the OR-NOT circuit chip is further introduced the intelligent switch machine equipment that the utility model provides for example below with the circuit chip.
As shown in Figure 4, the power supply circuits of intelligent switch machine equipment (routing device) comprise power supply, manual push-button switch, power devices module, OR-NOT circuit chip and the lead that is connected with the GND pin with the VCC pin of network interface card interface.
In the circuit structure shown in Figure 4, the network interface card interface of routing device is an example with 4, can certainly be the network interface card interface of 8 or other numbers.The OR-NOT circuit chip is connected respectively with the VCC pin of each network interface card interface, and the GND pin of network interface card interface interconnects among Fig. 4, and the OR-NOT circuit chip is connected with the GND pin.
In advance manual push-button switch is placed closure state, then when the conducting of OR-NOT circuit chip, the power supply circuits conducting, the power devices module is the routing device power supply, the routing device start; When the OR-NOT circuit chip was blocked, power supply circuits disconnected, and the power devices module stops to be routing device power supply, routing device shutdown.When the user does not need to use router for a long time, then disconnect manual button.
Concrete, when the arbitrary terminal equipment (computer) that is connected with routing device passes through the routing device access network, when being the network interface card work of arbitrary terminal equipment, the VCC pin level of corresponding network interface card interface will be greater than the GND pin level, the OR-NOT circuit chip detection is to this change in voltage, and the circuit between conducting A, the B connects, whole power supply circuits conducting, the power devices module is the routing device power supply, the routing device start; When a plurality of network interface cards of the network interface card interface correspondence of routing device powered on simultaneously, the OR-NOT circuit chip detection arrived the VCC pin voltage of a plurality of network interface cards greater than the GND pin voltage, and the circuit between conducting A, the B connects, whole power supply circuits conducting, device power-up; When the network interface card of all network interface card interface correspondences of routing device is not all worked, the VCC pin voltage of all network interface card interfaces equals the GND pin voltage, circuit between the blocking-up of OR-NOT circuit chip A, the B connects, whole power supply circuits blocking-up, the power devices module stops to be routing device power supply, routing device shutdown.
By adopting electro-detection electric supply installation and intelligent switch machine equipment on the network interface card that the utility model provides, automatic switch is set detects the VCC pin of network interface card interface and the voltage difference of GND pin, control appliance automatic power or outage automatically, thereby can realize the automatic switching of routing device, user-friendly, economize on resources.
