In the case where the first interface 150 is connected to a third interface of another electronic device, the converter 140 receives a second signal transmitted by the another electronic device and forms a second data path by connecting the first controller 160 and the first interface 150, so that data is transmitted between the electronic device and the another electronic device based on the second data path.
In the electronic device with the above structure, the first interface 150 is connected to the embedded controller 130 and the first controller 160 through the converter 140, and the converter 140 can switch modes to communicate the embedded controller 130 with the first interface 150 to form a first data path or communicate the first controller 160 with the first interface 150 to form a second data path. When the electronic device is connected to the detection apparatus 200 through the first interface 150, the electronic device can supply power to the detection apparatus 200 through the first interface 150, and the bios 110 can send detection data to the detection apparatus 200 through the first interface 150, so that the detection apparatus 200 is connected to the electronic device only through the first interface 150, which is convenient for the detection apparatus 200 to be connected or disconnected with the electronic device, and further facilitates a user to perform fault detection; when the electronic device is connected to another electronic device through the first interface 150, the electronic device can transmit data with the other electronic device by using the first controller 160, thereby ensuring the normal use function of the first interface 150.

When the converter 140 communicates the embedded controller 130 and the first interface 150 to form a first data path, the embedded controller 130 communicates with the SBU1 pin and the SBU2 pin at least through the converter 140, so that the detection data can be transmitted to the detection apparatus 200. When the converter 140 communicates the first controller 160 and the first interface 150 to form a second data path, the first controller 160 communicates with the SBU1 pin and the SBU2 pin at least through the converter 140, so as to be able to interact with another electronic device through the first interface 150. SBU1 pin and SBU2 pin are auxiliary pin in the USB Type-C interface, can have different usage under the use scene of difference, and electronic equipment passes through two pins of SBU1 pin and SBU2 pin and transmits detection data to detection device 200, can avoid influencing the normal use function of USB Type-C interface. Of course, the first interface 150 is not limited to the USB Type-C interface, and may also be, for example, a USB Type-a interface, a USB Type-B interface, or other interfaces having both data transmission and power supply functions.
In some embodiments, the embedded controller 130 is connected to the converter 140 via the fourth and fifth terminals, and when the converter 140 receives the first signal, the converter 140 connects the second terminal 152 and the fourth terminal to form a first sub-path, and connects the third terminal 153 and the fifth terminal to form a second sub-path, so as to form a first data path via the first sub-path and the second sub-path. Taking the electronic device as a notebook computer as an example, the notebook computer may include a motherboard 190, where the basic input output system 110 (BIOS), the embedded Controller 130 (EC), the first Controller 160, the converter 140, and the first Interface 150 may all be disposed on the motherboard 190, where the basic input output system 110 may be connected to the embedded Controller 130 through a south bridge chip 120, the basic input output system 110 may be connected to the south bridge chip 120 (a Platform Controller Hub, abbreviated as PCH) through a Serial Peripheral Interface (SPI), and data transmission may be performed between the two based on an SPI communication protocol; south bridge chip 120 may be connected to embedded controller 130 through an Enhanced-serial peripheral interface (Enhanced-SPI, abbreviated as eSPI), and data transmission may be performed between the two through an eSPI communication protocol; the embedded controller 130 and the first interface 150 may perform data transmission based on an I2C (Inter-Integrated Circuit) bus protocol, wherein the first sub-path may be used for transmitting a serial data signal, and the second sub-path may be used for transmitting a serial clock signal.
In some embodiments, the converter 140 receives a first signal generated by the detection device 200 by changing the input potentials of the second terminal 152 and the third terminal 153. For example, when the detection apparatus 200 is plugged into the first interface 150 of the electronic device through the second interface 210, the electronic device supplies power to the detection apparatus 200 through the first interface 150, and after the detection apparatus 200 is powered on, the input potentials of the second terminal 152 and the third terminal 153 can be pulled up from the low potential to the high potential, so as to generate the first signal. Specifically, the low potential may be, for example, 0V, and the high potential may be, for example, 3V. Of course, the aforementioned generation of the first signal by changing the input potentials of the second terminal 152 and the third terminal 153 is not limited to pulling up the input potentials of the second terminal 152 and the third terminal 153, and may be, for example, reducing the input potentials of the second terminal 152 and the third terminal 153.
In some embodiments, the electronic device further includes a first switching unit 170 and a second switching unit 180, the first switching unit 170 is connected to the power supply terminal of the electronic device, the second terminal 152 and the second switching unit 180, respectively, the second switching unit 180 is further connected to the third terminal 153 and the ground terminal of the electronic device, respectively, and the enable terminal of the converter 140 is connected between the power supply terminal of the electronic device and the first switching unit 170; the first and second switching units 170 and 180 receive the first signal, and transmit the first signal to the converter 140 by changing an input potential of an enable terminal of the converter 140. The first switch unit 170 and the second switch unit 180 may be a bipolar transistor, a darlington transistor, a thyristor, a field effect transistor, an insulated gate bipolar thyristor, or other switch units. Taking the first switch unit 170 and the second switch unit 180 both using field effect transistors as an example, a drain of a first field effect transistor as the first switch unit 170 may be connected to a power supply terminal of the main board 190 through a resistor, a source of the first field effect transistor may be connected to a drain of a second field effect transistor as the second switch unit 180, a gate of the first field effect transistor is connected to the second terminal 152, a gate of the second field effect transistor is connected to the third terminal 153, a source of the second field effect transistor may be connected to a ground terminal of the main board 190, and an enable terminal of the converter 140 is connected between the resistor and the first field effect transistor, so that when the second terminal 152 and the third terminal 153 are pulled up to a high potential from a low potential, the first field effect transistor and the second field effect transistor are both turned on, a path is formed between the power supply terminal of the main board 190 and the ground terminal of the main board 190 through the resistor, the first field effect transistor, and the second field effect transistor, and the enable terminal of the converter 140 is converted from a high potential to a low potential, so that the converter 140 receives the first signal. When the first switch unit 170 and the second switch unit 180 skillfully use the I2C bus protocol for data transmission, the high potential characteristic still needs to be maintained when the two buses are idle, so as to detect whether the device plugged on the first interface 150 is the detection apparatus 200 or another electronic device. If the detection apparatus 200 is plugged into the first interface 150, since it uses the I2C protocol for data transmission, the input potentials of the second terminal 152 and the third terminal 153 are inevitably raised to a high potential, at this time, it can be determined that the detection apparatus 200 is plugged into the first interface 150, and the potential of the enable terminal of the converter 140 is converted from the high potential to a low potential, so that the converter 140 receives the first signal and switches the data transmission mode, the structure is simple, it is not necessary to set a separate interaction path except for the first sub-path and the second sub-path, and the number of pins occupying the first interface 150 is small.
Referring to fig. 1 and fig. 3, an embodiment of the present invention further provides a detection system, which includes an electronic device 100 and a detection apparatus 200, where the electronic device 100 includes a basic input/output system 110, an embedded controller 130, a first controller 160, a converter 140, and a first interface 150, the basic input/output system 110 is connected to the converter 140 through the embedded controller 130, and the converter 140 is connected to the first controller 160 and the first interface 150, respectively; the detection apparatus 200 includes a detector 230, a power module 220, and a second interface 210, wherein the second interface 210 is respectively connected to an input terminal of the power module 220 and the detector 230, and an output terminal of the power module 220 is connected between the second interface 210 and the detector 230. Specifically, the detector 230 may be, for example, a detection chip or a logic circuit, and the power module 220 may be, for example, a power circuit or a power chip.
When the first interface 150 is connected to the second interface 210, the electronic device 100 supplies power to the power module 220 through the first interface 150, the power module 220 sends a first signal to the converter 140 through the second interface 210, the converter 140 communicates the embedded controller 130 and the first interface 150 based on the first signal to communicate the embedded controller 130 and the detector 230 to form a first data path, so that the bios 110 sends detection data to the detector 230 based on the first data path, and the detection apparatus 200 can detect a fault of the electronic device 100 based on the acquired detection data.
In the case that the first interface 150 is connected to the third interface of another electronic device 100, the converter 140 receives the second signal transmitted by the other electronic device 100 and forms a second data path by connecting the first controller 160 and the first interface 150, so that data is transmitted between the electronic device 100 and the other electronic device 100 based on the second data path.

When the electronic device 100 is connected to the detection apparatus 200 through the first interface 150, the electronic device 100 can supply power to the power module 220 of the detection apparatus 200 through the first interface 150, and further enable the bios 110 to send detection data to the detection apparatus 200 through the first interface 150, so that the detection apparatus 200 only needs to be connected to the electronic device 100 through the first interface 150, which is convenient for the detection apparatus 200 to be connected or disconnected to the electronic device 100, and further facilitates a user to perform fault detection; when the electronic device 100 is connected to another electronic device 100 through the first interface 150, the electronic device 100 can transmit data with another electronic device 100 by using the first controller 160, thereby ensuring the normal use function of the first interface 150.

Of course, the first interface 150 and the second interface 210 are not limited to USB Type-C interfaces, but may also be USB Type-a, USB Type-B or other interfaces having both data transmission and power supply functions.
In some embodiments, embedded controller 130 includes a fourth terminal and a fifth terminal, and in the case that converter 140 receives the first signal, converter 140 communicates second terminal 152 and the fourth terminal, such that embedded controller 130 communicates with detector 230 through the fourth terminal to form a first sub-path, and communicates third terminal 153 and the fifth terminal, such that embedded controller 130 communicates with detector 230 through the fifth terminal to form a second sub-path, such that a first data path is formed through the first sub-path and the second sub-path. Taking the electronic device 100 as a notebook computer as an example, the notebook computer may include a motherboard 190, where the basic input output system 110 (BIOS), the embedded Controller 130 (EC), the first Controller 160, the converter 140, and the first Interface 150 may all be disposed on the motherboard 190, where the basic input output system 110 may be connected to the embedded Controller 130 through a south bridge chip 120, the basic input output system 110 may be connected to the south bridge chip 120 (a Platform Controller Hub, abbreviated as PCH) through a Serial Peripheral Interface (SPI), and data transmission may be performed between the two based on an SPI communication protocol; south bridge chip 120 may be connected to embedded controller 130 through an Enhanced-serial peripheral interface (Enhanced-SPI, abbreviated as eSPI), and data transmission may be performed between the two through an eSPI communication protocol; the embedded controller 130 and the detector 230 may transmit data based on an I2C (Inter-Integrated Circuit) bus protocol, wherein the first sub-path may be used for transmitting a serial data signal and the second sub-path may be used for transmitting a serial clock signal.
In some embodiments, the power module 220 is powered on and generates the first signal by changing the input potentials of the second terminal 152 and the third terminal 153 through the seventh terminal 212 and the eighth terminal 213. Specifically, the power module 220 may be, for example, a power circuit or a power chip. For example, when the detection apparatus 200 is plugged into the first interface 150 of the electronic device 100 through the second interface 210, the electronic device 100 supplies power to the power module 220 of the detection apparatus 200 through the first end 151 and the sixth end 211, and after the power module 220 is powered on, the input potentials of the seventh end 212 and the eighth end 213 can be pulled up to a high potential, and further the input potentials of the second end 152 and the third end 153 are pulled up to a high potential from a low potential, so as to generate the first signal. The low potential may be, for example, 0V, and the high potential may be, for example, 3V. Of course, the aforementioned generation of the first signal by changing the input potentials of the second terminal 152 and the third terminal 153 is not limited to the pulling up of the input potentials of the second terminal 152 and the third terminal 153, and may be, for example, the lowering of the input potentials of the second terminal 152 and the third terminal 153.
In some embodiments, the electronic device 100 further includes a first switching unit 170 and a second switching unit 180, the first switching unit 170 is connected to the power supply terminal of the electronic device 100, the second terminal 152 and the second switching unit 180, respectively, the second switching unit 180 is further connected to the third terminal 153 and the ground terminal of the electronic device 100, respectively, and the enable terminal of the converter 140 is connected between the power supply terminal of the electronic device and the first switching unit 170; the first and second switching units 170 and 180 receive the first signal, and transmit the first signal to the converter 140 by changing an input potential of an enable terminal of the converter 140. The first switch unit 170 and the second switch unit 180 may be a bipolar transistor, a darlington transistor, a thyristor, a field effect transistor, an insulated gate bipolar thyristor, or other switch units. Taking the first switch unit 170 and the second switch unit 180 both using field effect transistors as an example, a drain of a first field effect transistor as the first switch unit 170 may be connected to a power supply terminal of the main board 190 through a resistor, a source of the first field effect transistor may be connected to a drain of a second field effect transistor as the second switch unit 180, a gate of the first field effect transistor is connected to the second terminal 152, a gate of the second field effect transistor is connected to the third terminal 153, a source of the second field effect transistor may be connected to a ground terminal of the main board 190, and an enable terminal of the converter 140 is connected between the resistor and the first field effect transistor, so that when the second terminal 152 and the third terminal 153 are pulled up to a high potential from a low potential, the first field effect transistor and the second field effect transistor are both turned on, a path is formed between the power supply terminal of the main board 190 through the resistor, the first field effect transistor and the second field effect transistor to the ground terminal of the main board 190, and an enable terminal of the converter 140 is converted from a high potential to a low potential, so that the converter 140 receives the first signal. When the first switch unit 170 and the second switch unit 180 skillfully utilize the I2C bus protocol for data transmission, the high potential characteristic still needs to be maintained when the two buses are idle, so as to detect whether the device plugged in the first interface 150 is the detection apparatus 200 or another electronic device 100. If the detection apparatus 200 is plugged in the first interface 150, since it uses the I2C protocol for data transmission, the input potentials of the second terminal 152 and the third terminal 153 are inevitably raised to a high potential, at this time, it can be determined that the detection apparatus 200 is plugged in the first interface 150, and the potential of the enable terminal of the converter 140 is converted from the high potential to a low potential, so that the converter 140 receives the first signal and switches the data transmission mode.
