The invention relates to a network communication status indicating device.

With the continuous development of the Internet, Internet access has become an indispensable feature of modern calculators. The networking methods of electronic products on the market mainly include wired connection and wireless connection.

Compared with the prior art, in the above network communication status indicating device, the indication circuit located on the front panel can directly indicate the current network communication status to the user. The user no longer has to look at the hidden indicator light in the network interface behind the main chassis.

The first output terminal 22 or the second output terminal 23 outputs a high level signal when the control signal is not output.

In another embodiment, when the motherboard 20 recognizes that the network interface 10 is connected to the network cable, the identification output terminal 21 outputs a low level signal as the first signal. When the motherboard 20 recognizes that the network interface 10 is not connected to the network cable, the identification output terminal 21 outputs a high level signal opposite to the first signal.

In another embodiment, the first output end 22 can output the control signal, the second output, when the data transmission speed between the motherboard 20 and the network cable is a first speed (eg, 1000 Mhz). The terminal 23 can output the control signal when the data transmission speed between the motherboard 20 and the network cable is a second speed (for example, 100 Mhz).

In still another embodiment, the network interface 10 is an RJ45 interface. The motherboard 20 includes a regional network chip capable of exchanging data with the network interface 10. The area network chip includes the identification output end 21, the first output end 22, and the second output end 23. The connector 30 includes a pin on the main board 20 and the front panel 40, and a cable for connecting the two rows of pins. Each row of pins has five pins.

In one embodiment, the anode of the first transistor D1 and the identification output terminal 21 are electrically connected by a resistor R1, and the anode is electrically connected to a high-level signal input terminal.

When the motherboard 20 recognizes that the network interface 10 is connected to the network cable, the identification output terminal 21 outputs the first signal to turn on the first transistor D1. When the motherboard 20 recognizes that the network interface 10 is not connected to the network cable, the first transistor D1 is turned off.

The second indicator module 412 includes a gate circuit 50 and a second transistor D2. The first output terminal 22 and the second output terminal 23 are electrically connected to the second transistor D2 by the NAND circuit 50. In one embodiment, the NAND circuit 50 is a two-input and gate circuit including a first input terminal 51 and a second input terminal 52.

In an embodiment, the anode of the second transistor D2 is electrically connected to the high-level signal input terminal via a resistor R2.

When there is data transmission between the motherboard 20 and the network cable, and the transmission rate reaches the first speed, the first output terminal 22 outputs the low level control signal, the second output. Terminal 23 outputs the high level signal. At this time, the AND gate circuit 50 outputs a low level signal to turn on the second transistor D2. When there is data transmission between the motherboard 20 and the network cable, and the transmission rate reaches the second speed, the second output terminal 23 outputs the low level control signal, the first output. Terminal 22 outputs the high level signal. At this time, the AND gate circuit 50 outputs a low level signal to turn on the second transistor D2. Since the control signal is a pulse signal, the conduction frequency of the second transistor D2 is consistent with the frequency of the pulse signal.

When there is no data transmission between the motherboard 20 and the network cable, the first output terminal 22 and the second output terminal 23 output the high level signal. At this time, the AND gate circuit 50 outputs a high level signal to cause the second transistor D2 to be turned off.

In an embodiment, the first transistor D1 and the second transistor D2 are both light emitting diodes. When the motherboard 20 recognizes that the network interface 10 is connected to the network cable, the first transistor D1 located on the front panel 40 emits light. When there is data transmission between the motherboard 20 and the network cable, the second transistor D2 located on the front panel 40 flashes and emits light.
