[0096] It should be noted that when the interface type information of the Ethernet interface matches the type information associated with the current relay, the powered device can, but is not limited to, control the target switch to switch from the default on state to the off state by issuing a graded current, and then connect the line from the detection resistor to the head of the powered device to the relay to the tail of the powered device to the second pin of the microcontroller, and the second signal information associated with the second pin indicates the presence of a voltage or current signal.

[0097] It should be noted that the matching of the interface type information of the Ethernet interface and the type information associated with the current relay can be, but is not limited to, obtaining the current circuit information of the detection circuit by using a detection resistor, wherein the current circuit information is used to indicate whether there is a handshake chip on the Ethernet interface; when the current circuit information indicates that there is a handshake chip on the Ethernet interface, it is determined whether the handshake protocol associated with the handshake chip matches the first protocol type; when the handshake protocol matches the first protocol type, the interface type information of the Ethernet interface matches the type information associated with the current relay.

[0098] Through the embodiments provided by the present application, detection information associated with the detection resistor is obtained through the header of the powered device associated with the Ethernet interface, wherein the header is connected between the detection resistor and the first relay; when the detection information indicates a pass, a graded current emitted by the header is obtained, wherein the graded current is used to request to turn off the target switch at the tail of the photodiode chip, wherein the tail is connected between the first relay and the first pin; when the graded current successfully turns off the target switch, it is determined that the second pin obtains second signal information indicating the presence of a voltage or current signal, thereby achieving the purpose of improving the accuracy of determining the interface type of the Ethernet, thereby achieving the technical effect of improving the detection accuracy of the Ethernet interface.

[0103] Optionally, in this embodiment, the detection resistor can be used, but is not limited to, to detect whether there is a handshake chip in the current Ethernet interface. It can also be used, but is not limited to, to determine whether the handshake protocol of the handshake chip matches the type protocol associated with the relay when there is a handshake chip in the current Ethernet interface.

[0104] Optionally, in this embodiment, the detection resistor may also be, but is not limited to, a dummy load, which may be, but is not limited to, ensuring that no overcurrent occurs under the minimum output power type protocol.

[0105] It should be noted that the detection resistor can also be used, but is not limited to, to screen non-standard Ethernet interfaces. Non-standard Ethernet interfaces do not have handshake chips and their corresponding circuit information does not have a handshake protocol. The current in the circuit corresponding to the non-standard Ethernet interface cannot pass through the detection resistor.

[0106] Through the embodiments provided by the present application, a detection resistor is used to obtain current circuit information of a detection circuit, wherein the current circuit information is used to indicate whether a handshake chip exists in the Ethernet interface; when the current circuit information indicates that a handshake chip exists in the Ethernet interface, it is determined whether the handshake protocol associated with the handshake chip matches a first protocol type; when the handshake protocol matches the first protocol type, it is confirmed that the detection information has passed. By using the detection resistor and the handshake result to determine whether the current Ethernet interface type is a non-standard type, it is also possible to further determine the protocol type of the current Ethernet interface type, thereby achieving the purpose of improving the accuracy of determining the Ethernet interface type, thereby achieving the technical effect of improving the detection accuracy of the Ethernet interface.

[0107] As an optional solution, after obtaining the first signal information associated with the first pin, the method further includes:

[0115] Optionally, when the interface type information of the Ethernet interface is determined, corresponding prompt information is displayed on the display screen.

[0116] For example, when it is determined that the Ethernet interface is not a non-standard type, the display screen may, but is not limited to, display the message "This Ethernet interface is not a non-standard type, please further check whether it is a BT type"; or when it is determined that the Ethernet interface is not a non-standard type and is not a BT type, the display screen may, but is not limited to, display the message "This Ethernet is not a BT type, please further check whether it is an AT type".

[0117] The embodiment provided by this application, as an optional solution, displays the interface type information of the Ethernet interface on a display screen connected to the single-chip microcomputer after the interface type information of the Ethernet interface is determined. By providing timely feedback of the current detection results, the speed and richness of the information feedback of Ethernet interface detection are improved, thereby achieving the technical effect of improving the accuracy and efficiency of Ethernet interface detection.

[0118] As an optional solution, the Ethernet interface detection method is applied to a portable PSE power supply mode automatic detection system, such as Figure 4 As shown, the system includes an RJ45 interface 1, a rectifier bridge 2, a voltage divider resistor 3, a voltage divider resistor 4, a voltage regulator diode 5, a relay 6, a relay 7, a relay 8, a PSE access detection resistor 9, a PD chip 10, a high-precision current sensor 11, a power resistor 12, a single-chip microcomputer 13, an LCD screen 14, a lithium battery 15, a power module 16, a voltage follower 17, a BT grading resistor 19, an AT grading resistor 20, and an AF grading resistor 21.

[0119] Among them, the PD chip 10 includes a switch 18 inside, which is controlled by the PD chip 10. The switch 18 connects pin 2 of the PD chip 10 and pin 4 of the PD chip. Pin 1 of the PD chip is the POE protocol detection pin, and pin 3 of the PD chip is the POE protocol classification pin.

[0120] RJ45 port 1 is connected to the AC input of bridge rectifier 2. The DC output of bridge rectifier 2 is connected to the cathode of voltage regulator 5, the PSE is connected to one end of detection resistor 9, and finally, through high-precision current sensor 11, is connected to one end of power resistor 12. The other end of power resistor 12 is connected to pin 4 of PD chip 10.

[0121] The anode of the voltage regulator 5 is connected to one end of the voltage divider resistor 4, and the other end of the resistor 4 is connected to one end of the voltage divider resistor 3 and the input port of the voltage follower 17. The other end of the resistor 3 is connected to the DC input end of the rectifier bridge 2 and pin 2 of the PD chip.

[0122] Pin 3 of PD chip 10 is connected to the inputs of relays 6, 7, and 8. The normally-open output of relay 6 is connected to one end of AF grading resistor 21, the other end of which is connected to the DC input of rectifier bridge 2 and pin 2 of PD chip 10. The normally-open output of relay 7 is connected to one end of AT grading resistor 20, the other end of which is connected to the DC input of rectifier bridge 2 and pin 2 of PD chip 10. The normally-open output of relay 8 is connected to one end of BT grading resistor 19, the other end of which is connected to the DC input of rectifier bridge 2 and pin 2 of PD chip 10.

[0123] Among them, the control pins of relay 6 are respectively connected to pin 5 of the single-chip microcomputer 13 , the control pins of relay 7 are respectively connected to pin 4 of the single-chip microcomputer 13 , and the control pins of relay 8 are respectively connected to pin 3 of the single-chip microcomputer 13 .

[0124] The signal output of high-precision current sensor 11 is connected to pin 2 of microcontroller 13, and the output of voltage follower 17 is connected to pin 1 of microcontroller 13. Microcontroller 13 and LCD screen 14 are connected via a flat cable. Lithium battery 15 is connected to the input of power module 16, and the output of power module 16 is connected to microcontroller 13.

[0125] When the system is working, connect the lithium battery 115 to the system to ensure normal operation of the system. Connect the POE interface (i.e., Ethernet interface, the same below) to be tested to the RJ45 interface 1 through a network cable to ensure that all devices in the system are connected normally.

[0126] Furthermore, in the case where the POE interface to be tested is a non-standard POE interface, the current flow direction of the above portable PSE power supply automatic detection system is shown as follows: Figure 5 shown.

[0127] Specifically, after rectification by the rectifier bridge 2, a high voltage is generated at the DC output and DC input ends of the rectifier bridge 2, causing the voltage regulator 5 to be turned on. The current flows from the DC output end into the cathode of the voltage regulator 5, flows out from the anode of the voltage regulator 5, passes through the voltage divider resistor 4, and then flows back to the DC input end of the rectifier bridge 2 after the voltage divider resistor 3. The voltage divider value between the voltage divider resistors 3 and 4 is collected by pin 2 of the single-chip microcomputer 13 through the voltage follower 17. At this time, the PD chip 10 has not received the handshake chip of the POE, does not control the internal switch 18 to be closed, no current flows through the power resistor 12, and the high-precision current sensor 11 has no detection signal transmitted to pin 2 of the single-chip microcomputer 13. There is no signal at pin 2 of the single-chip microcomputer, but there is a signal at pin 1. It is judged that the POE port is non-standard POE, and "non-standard POE" is displayed on the LCD screen 14.

[0128] based on Figure 4 The portable PSE power supply mode automatic detection system shown enters the BT interface detection when the single chip microcomputer 13 determines that the access interface is not a non-standard POE interface.

[0129] Specifically, the current flow diagram during BT protocol detection is as follows: Figure 6As shown, pin 3 of microcontroller 13 controls relay 8 to close, connecting PD chip 10's classification detection pin 3 to BT detection resistor 19. The POE detection signal at the DC output of rectifier bridge 2 is first detected by detection resistor 9. After a successful handshake, PD chip 10's control pin 3 sends a classification current. The classification current passes through relay 8, BT classification resistor 19, and the DC input of rectifier bridge 2, and finally flows back to the PSE through RJ45 port 1.

[0130] Furthermore, when the POE interface to be tested is not a non-standard POE interface but a BT protocol type interface, the current flow direction of the above portable PSE power supply automatic detection system is shown as follows: Figure 7 As shown in the figure, the internal MOS of the PSE device (device under test) at the other end is closed, and the PD chip 10 controls the switch 18 to close, turning on the power resistor 12. The current passes through the high-precision current sensor 11, generating a sensing signal that is sent to pin 2 of the microcontroller 13. The microcontroller then controls the LCD screen 14 to display "BT device connected."

[0131] based on Figure 4 The portable PSE power supply mode automatic detection system shown enters the AT interface detection when the single chip microcomputer 13 determines that the access interface is not a BT interface.

[0132] Specifically, the current flow diagram during AT protocol detection is as follows: Figure 8 As shown, pin 3 of microcontroller 13 controls relay 8 to open, while pin 4 of microcontroller 13 controls relay 7 to close, connecting the PD's classification detection pin 3 to the AT detection resistor 20. The POE detection signal at the DC output of rectifier bridge 2 is first detected by detection resistor 9. After a successful handshake, control pin 3 of PD chip 10 generates a classification current. The shunt classification current passes through relay 7, AT classification resistor 20, and the DC input of rectifier bridge 2, and finally flows back to the PSE through RJ45 port 1.

[0133] Furthermore, in the case where the POE interface to be tested is not a BT interface but an AT protocol type interface, the current flow direction of the above portable PSE power supply automatic detection system is shown as follows: Figure 9 shown.

[0134] The internal MOS of the PSE device (device under test) at the other end is closed, and the PD chip controls switch 18 to close, turning on power resistor 12. The current passes through high-precision current sensor 11, generating an induction signal that is sent to pin 2 of microcontroller 13. The microcontroller then controls LCD screen 14 to display "AT device connected."

[0135] based on Figure 4The portable PSE power supply mode automatic detection system shown enters the AF interface detection when the single chip microcomputer 13 determines that the access interface is not the AT interface.

[0136] Specifically, the current flow diagram during AF protocol detection is as follows: Figure 10 As shown, pin 4 of microcontroller 13 controls relay 7 to open, while pin 5 of microcontroller 13 controls relay 6 to close, connecting the PD's classification detection pin 3 to af detection resistor 21. The POE detection signal at the DC output of rectifier bridge 2 is first detected by detection resistor 9. After a successful handshake, control pin 3 of PD chip 10 generates a classification current. The shunt classification current passes through relay 6, af classification resistor 21, and the DC input of rectifier bridge 2, and finally flows back to the PSE through RJ45 port 1.

[0137] Furthermore, when the POE interface to be tested is not an AT interface but an AF protocol type interface, the current flow direction of the above portable PSE power supply automatic detection system is shown as follows: Figure 11 As shown in the figure, the internal MOS of the PSE device (device under test) at the other end is closed, the PD chip controls switch 18 to close, power resistor 12 is turned on, and the induction signal generated by the current passing through high-precision current sensor 11 is sent to pin 2 of microcontroller 13. The microcontroller then controls LCD screen 14 to display "AF device connected."

[0138] It should be noted that the PD chip 10 depends on the model.

[0139] It should be noted that the single chip microcomputer 13 depends on the model.

[0140] It should be noted that the power resistor 9 is a dummy load, and can be about 200Ω, which can ensure that no overcurrent occurs under the AF protocol.

[0141] It should be noted that the resistance of voltage divider resistors 3 and 4 is at the K level to prevent the resistance from being too low and affecting the POE handshake protocol. Here, 10K is selected.

[0142] It should be noted that the voltage specification of the Zener diode is less than 42V to prevent the resistance from being too low and affecting the POE handshake protocol. 40V can be selected, but is not limited to it.

[0143] It should be noted that the BT grading resistor can be but is not limited to 19 ohms; the AT grading resistor can be but is not limited to 20 ohms; the AF grading resistor can be but is not limited to 21 ohms; the specific resistance value depends on the specifications of different PD chips.

[0144] It should be noted that the LCD screen 14 depends on the video interface of the single chip microcomputer 13 and can be an LCD screen, an OLED screen, etc.

[0145] It should be noted that the output voltage of the power module 12 depends on the voltage required by the single chip computer 13 and can be 5V or 3.3V.

[0148] In step S1204 , pins 3 , 4 , and 5 of the single chip microcomputer 13 control the relays 6 , 7 , and 8 to be disconnected respectively.

[0149] Step S1206, the single chip microcomputer 13 detects whether there is a signal on pin 1;

[0150] Step S1208: If there is a signal on pin 1, the MCU 13 controls the LCD screen 14 to display "non-POE device" and returns to step S1204;

[0151] Step S1210: If there is no signal at pin 1, it indicates that no POE device is connected or a standard POE device is connected, and further detection is required. The microcontroller 13 controls pin 5 to close the relay 8.

[0152] Step S1212, the single chip computer 13 detects whether there is a signal on pin 2;

[0153] Step S1214: If there is a signal on pin 2, the MCU 13 controls the LCD screen 14 to display "BT protocol POE device" and returns to step S1204;

[0154] Step S1216: If there is no signal on pin 2, it means that no POE device is connected or the connected device is an AT / AF protocol POE device, and further detection is required. The microcontroller 13 controls pin 5 to disconnect relay 8 and pin 4 to close relay 7.

[0155] Step S1218, the single chip computer 13 detects whether there is a signal on pin 2;

[0156] Step S1220: If there is a signal on pin 2, the MCU 13 controls the LCD screen 14 to display "AT protocol POE device" and returns to step S1204;

[0157] Step S1222: If there is no signal on pin 2, it indicates that no POE device is connected or the connected device is an AF protocol POE device, and further detection is required. The microcontroller 13 controls pin 4 to disconnect the relay 7 and pin 3 to close the relay 6.

[0158] Step S1224, the single chip microcomputer 13 detects whether there is a signal on pin 2;

[0159] Step S1226: If there is a signal on pin 2, the MCU 13 controls the LCD screen 14 to display "af protocol POE device" and returns to step S1204;

[0160] Step S1228: If there is no signal on pin 2, the MCU 13 controls the LCD screen 14 to display "No POE device connected" and returns to step S1204.

[0161] The above method greatly shortens the debugging time of equipment debugging personnel. The existing technology requires searching the equipment manual to determine the relevant information of the POE interface, which is inefficient. The above method can automatically identify the POE interface, saving time and effort.

[0162] The above method effectively reduces equipment damage and accidents. Non-standard POE can not only damage non-PD devices but can even cause fires and endanger lives. The above method can identify non-standard POE and reduce the failure and accident rates of non-PD devices.

[0163] The above method is easy to use. Simply plug in the network cable and you can view POE-related information on the screen, freeing up productivity. Even non-professionals can operate it.
