Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
FIG. 1 is a functional block diagram of a network interface 10 connected to an electronic device 70, a network 80 and a monitoring device 90 according to an embodiment of the present invention. The network interface 10 includes an RJ45 connector 20, a network card 30 and a switching circuit 40. The RJ45 connector 20 is configured to couple to an RJ45 interface 72 of an electronic device 70 to be monitored. The network card 30 can receive packets and signals from the network 80 through the network line 50 and transmit the packets and signals to the network 80 through the network line 50. The network 80 may be the Internet or a local area network. The switching circuit 40 may be coupled to the communication interface 60 of the monitoring device 90. The monitoring device 90 can be coupled to the electronic equipment 70 through the communication interface 60 and the switching circuit 40 and the RJ45 connector 20 in the network interface 10, and monitor the status of the electronic equipment 70. In another embodiment of the present invention, the monitoring device 90 can also transmit related commands and data to the electronic device 70 through the communication interface 60, the switching circuit 40 and the RJ45 connector 20 in the network interface 10, so as to update the firmware of the chip 74 of the electronic device 70.
FIG. 2 is a pin layout diagram of the network interface 10 of FIG. 1. The RJ45 connector 20 includes a first set of pins G1 and a second set of pins G2. The first group of pins G1 comprises a plurality of pins A1, A2, A3 and A6, and the second group of pins G2 comprises a plurality of pins A4, A5, A7 and A8. In addition, the RJ45 connector 20 is used to receive network packets and signals from the network line 50 and send the network packets and signals to the network line 50. The other end of the network line 50 can be coupled to the internet, a local area network or another electronic device. The network card 30 includes a third pin G3 and a fourth pin G4. The third set of pins G3 includes a plurality of pins B1, B2, B3, and B6, and the fourth set of pins G4 includes a plurality of pins B4, B5, B7, and B8. Pins B1, B2, B3, and B6 are coupled to pins A1, A2, A3, and A6, respectively.
The switch circuit 40 includes a first interface 41, a second interface 42, and a third interface 43. The first interface 41 includes a plurality of pins 11-14, the second interface 42 includes a plurality of pins 21-24, and the third interface 43 includes a plurality of pins 31-34. The pins 11-14 of the first interface 41 are coupled to the pins A4, A5, A7 and A8 of the second set of pins G2, respectively, the pins 21-24 of the second interface 42 are coupled to the pins B4, B5, B7 and B8 of the fourth set of pins G4, respectively, and the pins 31-34 of the third interface 43 are coupled to the communication interface 60. The third interface 43 and the communication interface 60 communicate with each other by using the same communication protocol, and the third interface 43 and the communication interface 60 may be Universal Asynchronous Receiver/Transmitter (UART), universal Serial Bus (USB), inter-Integrated Circuit (I2C), secure Digital Input/Output (SDIO), or Joint Test Group (JTAG).
In an embodiment of the invention, when the switching circuit 40 determines that the signal S1 received from the third interface 43 includes the predetermined string, the switching circuit 40 couples the first interface 41 to the third interface 43 and disconnects the electrical connection between the first interface 41 and the second interface 42. Thus, the pins A4, A5, A7, and A8 of the second group G2 of the RJ45 connector 20 are coupled to the pins 31 to 34 of the third interface 43, respectively. In this case, the RJ45 connector 20 can communicate with the monitoring device 90 through the second set of pins G2 and the third interface 43, and the RJ45 connector 20 can also communicate with the third set of pins G3 of the network card 30 through the first set of pins G1. Therefore, the monitoring device 90 can monitor the status of the electronic device 70 or update the firmware of the chip 74 of the electronic device 70 through the third interface 43 and the first interface 41. Meanwhile, the electronic device 70 may be connected to the network 80 through the first and third sets of pins G1 and G3. At this time, the transmission rate between the electronic device 70 and the network 80 is a first transmission rate, and the first transmission rate may be 100 megabits per second (i.e., 100 Mbps), but the invention is not limited thereto. The length and content of the predetermined string contained in the signal S1 are mainly determined by the monitoring device 90, the predetermined strings contained in the signal S1 of different monitoring devices 90 may be different from each other, and the switching circuit 40 may be designed to determine different predetermined strings generated by different monitoring devices 90, and couple the first interface 41 to the second interface 42 or the third interface 43 according to whether the signal S1 contains the predetermined string. On the other hand, when the switching circuit 40 does not determine that the signal S1 received from the third interface 43 contains the predetermined string (e.g., the third interface 43 does not receive the signal S1, or the received signal S1 does not contain the predetermined string), the switching circuit 40 couples the first interface 41 to the second interface 42 and disconnects the electrical connection between the first interface 41 and the third interface 43. In this way, the pins A4, A5, A7 and A8 of the second set of pins G2 of the RJ45 connector 20 are coupled to the pins 21 to 24 of the second interface 42, respectively. In this case, the pins A4, A5, A7, and A8 of the second set of pins G2 of the RJ45 connector 20 are coupled to the pins B4, B5, B7, and B8 of the fourth set of pins of the network card 30 via the pins 11 to 14 and 21 to 24, respectively. At this time, the transmission rate between the electronic device 70 and the network 80 is a second transmission rate, and the second transmission rate is higher than the first transmission rate. For example, the first transmission rate may be 100Mbps (i.e., 100 Mbps), and the second transmission rate may be 1000Mbps (i.e., 1000 Mbps), but the invention is not limited thereto.
In another embodiment of the present invention, when the switching circuit 40 does not determine that the signal S1 received from the third interface 43 includes the predetermined string (e.g., the third interface 43 does not receive the signal S1, or the received signal S1 does not include the predetermined string), the switching circuit 40 couples the first interface 41 to the third interface 43 and disconnects the electrical connection between the first interface 41 and the second interface 42. In this way, the pins A4, A5, A7 and A8 of the second set of pins G2 of the RJ45 connector 20 are coupled to the pins 31 to 34 of the third interface 43, respectively. In this case, the RJ45 connector 20 can communicate with the monitoring device 90 through the second set of pins G2 and the third interface 43, and the RJ45 connector 20 can also communicate with the third set of pins G3 of the network card 30 through the first set of pins G1. Therefore, the monitoring device 90 can monitor the status of the electronic device 70 or update the firmware of the chip 74 of the electronic device 70 through the third interface 43 and the first interface 41. Meanwhile, the electronic device 70 may be connected to the network 80 through the first and third sets of pins G1 and G3. At this time, the transmission rate between the electronic device 70 and the network 80 is the first transmission rate. On the other hand, when the switching circuit 40 determines that the signal S1 received from the third interface 43 contains the predetermined string, the switching circuit 40 couples the first interface 41 to the second interface 42 and disconnects the electrical connection between the first interface 41 and the third interface 43. In this way, the pins A4, A5, A7 and A8 of the second set of pins G2 of the RJ45 connector 20 are coupled to the pins 21 to 24 of the second interface 42, respectively. In this case, the pins A4, A5, A7, and A8 of the second set of pins G2 of the RJ45 connector 20 are coupled to the pins B4, B5, B7, and B8 of the fourth set of pins of the network card 30 via the pins 11 to 14 and 21 to 24, respectively. At this time, the transmission rate between the electronic device 70 and the network 80 is a second transmission rate, and the second transmission rate is higher than the first transmission rate.
Since the network interface 10 is coupled to the RJ45 interface 72 of the electronic device 70 through the RJ45 connector 20, the RJ45 interface 72 is an interface still used by the electronic device 70 after being shipped. Therefore, according to the above embodiment of the present invention, the monitoring device 90 can be connected to the RJ45 interface 72 of the electronic device 70 through the network interface 10 to monitor and update the firmware of the electronic device 70. Meanwhile, the electronic equipment 70 can still be connected to the network 80 through the RJ45 interface 72 and the network interface 10. Therefore, the electronic device 70 can be connected to the monitoring device 90 through the original RJ45 interface 72 without installing another interface. Therefore, not only the configuration space of the electronic device 70 can be saved, but also the related personnel can connect the monitoring device 90 to the electronic device 70 through the network interface 10 to monitor and update the firmware of the electronic device, and the function of connecting the electronic device 70 to the network 80 is also retained.
The present invention has been described in relation to the above embodiments, which are only examples of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
