[0035] Based on the above, the first embodiment of the computer remote control circuit of the application is proposed. Please refer to Figure 1 , Figure 1 The schematic diagram of the first embodiment of the computer remote control circuit of the application.

[0036] In the embodiment, the computer remote control circuit comprises a control end 10, a controlled end 20 and a docking station 30; the controlled end 20 comprises a first HDMI interface 201, a first USB interface 202 and a mainboard circuit 203, the control end 10 comprises a first RJ45 Ethernet interface 101; the docking station 30 comprises a second HDMI interface 301, a second USB interface 302, a system chip 303 and a second RJ45 Ethernet interface 304, and the second RJ45 Ethernet interface 304 supports POE technology;

[0037] The second HDMI interface 301, the second USB interface 302 and the second RJ45 Ethernet interface 304 are connected with the system chip 303;

[0038] The first HDMI interface 201 is connected with the second HDMI interface 301, the first USB interface 202 is connected with the second USB interface 302, and the mainboard circuit 203 is connected with the system chip 303;

[0039] The second RJ45 Ethernet interface 304 is connected with the first RJ45 Ethernet interface 101.

[0040] It should be noted that the control end 10 refers to a computer that remotely sends control instructions, the controlled end 20 refers to a computer that is remotely controlled, and the control end 10 has all the functions of a computer except the first RJ45 Ethernet interface 101. The mainboard circuit 203 is a circuit in a computer that can control the on-off of power, and the system chip 303 is SOC, which integrates most components of an entire electronic system. In addition, the first RJ45 Ethernet interface 101 represents the RJ45 Ethernet interface on the control end 10 side. If the control end 10 itself does not have an RJ45 Ethernet interface, it can also indirectly connect the RJ45 Ethernet interface through an adapter. The second RJ45 Ethernet interface 304 represents the RJ45 Ethernet interface in the docking station 30. In a feasible implementation, the second RJ45 Ethernet interface 304 and the first RJ45 Ethernet interface 101 can be connected through IP addresses.

[0041] In the embodiment, the docking station 30 can receive the video signal (for example, TMDS signal) from the controlled terminal 20 through the second HDMI interface 301, receive the data signal from the controlled terminal 20 through the second USB interface 302, and convert the signal through the signal conversion function of the system-level chip 303 (for example, convert the signal into a data format that can be transmitted on the TCP / IP protocol), and then transmit the converted signal to the control terminal 10 through the second RJ45 Ethernet interface 304. The control terminal 10 can autonomously analyze the received signal and output the information corresponding to the signal to the display of the control terminal 10, and then obtain the control signal for controlling the controlled terminal 20 through the HID instruction control on the control terminal 10. Then, the control signal can be transmitted to the second RJ45 Ethernet interface 304 of the docking station 30 through the first RJ45 Ethernet interface 101 of the control terminal 10, so that the docking station 30 transmits the control signal to the controlled terminal 20 through the connection between the HDMI interfaces and through the connection between the USB interfaces, so that the controlled terminal 20 responds to the control signal. When the controlled terminal 20 is powered off, the control terminal 10 can transmit the signal for turning on the power to the docking station 30 through the connection between the first RJ45 Ethernet interface 101 and the second RJ45 Ethernet interface 304 supporting the POE technology, and then through the connection between the system-level chip 303 and the mainboard circuit 203 in the docking station 30, so that the mainboard circuit 203 can automatically turn on the power of the controlled terminal 20 after receiving the signal indicating turning on the power, thereby achieving the purpose that the controlled terminal 20 and the control terminal 10 can stably communicate. In addition, compared with the traditional computer remote control mode realized by software, the computer remote control circuit proposed in the application has the advantage of high safety because it is realized by hardware connection.

[0044] In the embodiment, the power module in the docking station 30 can supply power to the hardware in the docking station 30 that needs power, so as to ensure that the docking station 30 can work normally when the device connected with the docking station 30 (for example, the controlled terminal 20) is powered off.

[0045] In an embodiment, the docking station 30 further comprises a power management chip, one end of the power management chip is connected with the output pin of the power module, and the other end of the power management chip is connected with the second HDMI interface 301, the second USB interface 302, the system chip 303 and the second RJ45 Ethernet interface 304.

[0046] In the embodiment, the power management chip can be connected between the power module and the hardware requiring power in the docking station 30, so that the service life of the hardware in the docking station 30 can be improved based on the voltage regulation and current control functions of the power management chip.

[0047] In an embodiment, the docking station 30 further comprises an LED indicator, the positive electrode of the LED indicator is connected with the output pin of the power module, and the negative electrode of the LED indicator is connected with the ground pin of the power module.

In the embodiment, when the docking station 30 has the storage module, the communication data between the control end 10 and the controlled end 20 can be stored by the storage module, so as to determine whether the communication process between the control end 10 and the controlled end 20 is abnormal based on the stored data.

[0052] In the embodiment, in addition to the current control function of the power management chip to improve the service life of the docking station 30, the overcurrent protection module can also be used to improve the service life of the docking station 30.

[0053] Specifically, the overcurrent protection module comprises a first self-resetting fuse, a second self-resetting fuse, a third self-resetting fuse and a fourth self-resetting fuse.

[0055] One end of the second self-recovery fuse is connected with the output pin of the power module, and the other end of the second self-recovery fuse is connected with the second USB interface 302.

[0056] One end of the third self-recovery fuse is connected with the output pin of the power module, and the other end of the third self-recovery fuse is connected with the system-level chip 303.

[0057] One end of the fourth self-recovery fuse is connected with the output pin of the power module, and the other end of the fourth self-recovery fuse is connected with the second RJ45 Ethernet interface 304.

[0058] In the embodiment, when only the second HDMI interface 301, the second USB interface 302, the system-level chip 303 and the second RJ45 Ethernet interface 304 in the docking station 30 are hardware that needs to be powered, the self-recovery fuses can be connected in series on the power supply circuit, so as to avoid the problem of hardware damage caused by excessive current, and improve the service life of the docking station 30.

[0061] In the embodiment, the communication between the controlled end 20 and the control end 10 is remote communication, and therefore the amplification circuit 305 and the filtering circuit 306 can be connected in series between the system-level chip 303 and the second RJ45 Ethernet interface 304, so as to ensure the accuracy of the remote communication.

[0062] Please refer to Figure 4 In a feasible implementation, the docking station 30 further comprises a display 307, which is connected with the system-level chip 303.

[0063] In the embodiment, the display 307 is used to output the state information related to the docking station 30. For example, the display 307 can be used to output the state of the connected device, the network speed, the USB port occupation.

[0064] In the embodiment, the docking station 30 in the computer remote control circuit can be used to transmit information between the controlled end and the control end 10, and since the RJ45 Ethernet interface in the docking station 30 supports the POE technology, even if the controlled end is powered off, the docking station 30 can still deliver the instruction of turning on the power to the controlled end based on the POE technology, so that the controlled end can still be controlled by the control end 10. It can be seen that the computer remote control circuit provided by the application can improve the stability of the computer remote control.
