[0002] With users increasingly demanding thinner and lighter designs, most mainstream electronic devices use the Type-C interface for interaction. The application of Type-C is very widespread, and its functions are becoming more diversified, such as integrating charging, data transmission, and video display functions.

[0003] Different Type-C cables integrate different functions. For example, a Type-C cable for a power bank only has a charging function. This makes it impossible for users to determine the functions of a Type-C cable from its appearance. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a Type-C cable type detection system and method.

[0005] The technical solution adopted in this invention is:

[0009] The second Type-C connector connects to the input pins of the MCU microcontroller;

[0010] The LED light control module connects to the output control pin of the MCU microcontroller;

[0011] When the Type-C cable to be tested is inserted into the first Type-C socket and the second Type-C socket, the MCU microcontroller receives the Type-C interface signal through the input pin; determines the pin level information of all pins based on the Type-C interface signal; determines whether the Type-C cable to be tested supports the cable function based on the pin level information; generates the corresponding LED control signal based on whether the cable function is supported; and sends the LED control signal to the LED control module.

[0012] The LED light control module controls the corresponding LED light to turn on or off based on the LED light control signal.

[0013] Furthermore, the input pins include:

[0014] Ground (GND) pin, power supply (VBUS) pin, charging (CC) pin, data transmission pin, and high-speed data transmission pin;

[0016] The high-speed data transmission pins include the TX1+ pin, TX1- pin, RX1+ pin, and RX1- pin.

[0017] Furthermore, based on the pin level information, the cable functions supported by the Type-C cable under test can be determined, including:

[0018] Based on the pin level information, determine whether the pin level of GND pin, VBUS pin, CC pin, D+ pin, D- pin, TX1+ pin, TX1- pin, RX1+ pin, and RX1- pin is high or low.

[0019] If at least one of the GND and VBUS pins is high, then the Type-C cable under test does not support all cable functions.

[0020] If the pin levels of GND and VBUS are both low, then the support for charging function is determined by the pin level of CC, the support for data transmission function is determined by the D+ and D- pins, and the support for video transmission function is determined by the TX1+, TX1-, RX1+, and RX1- pins.

[0021] If the CC pin is at a high level, it is determined that the Type-C cable under test does not support charging.

[0022] If the CC pin is at a low level, it is determined that the Type-C cable under test supports charging.

[0023] If at least one of the D+ and D- pins is high, it is determined that the Type-C cable under test does not support data transmission.

[0024] If both the D+ and D- pins are low, it is determined that the Type-C cable under test supports data transmission.

[0025] If at least one of the TX1+ pin, TX1- pin, RX1+ pin, and RX1- pin is high, then the Type-C cable under test does not support video transmission.

[0026] If the TX1+, TX1-, RX1+, and RX1- pins are all at a low level, then the Type-C cable under test is confirmed to support video transmission.

[0027] Furthermore, the LED light control module includes:

[0039] Furthermore, when the LED control signal is high on pin P1, the first MOSFET is turned on, causing LED1 to light up.

[0040] When the LED control signal is low on pin P1, the first MOSFET is not turned on, causing LED1 to turn off.

[0041] When the LED control signal is high on pin P2, the second MOSFET is turned on, causing LED2 to light up.

[0042] When the LED control signal is low on pin P2, the second MOSFET is not turned on, causing LED2 to turn off.

[0043] When the LED control signal is high on pin P3, the third MOSFET is turned on, causing LED3 to light up.

[0044] When the LED control signal is low on pin P3, the third MOSFET is not turned on, causing LED3 to turn off.

[0045] Furthermore, the MCU microcontroller detects in real time whether the Type-C cable to be tested is inserted, including:

[0046] When the MCU microcontroller determines that the Type-C cable is not inserted, it indicates that all pin levels are high based on the Type-C interface signals received from the input pins.

[0047] When the Type-C cable is not plugged in, the MCU outputs a low level to the P1, P2 and P3 pins.

[0048] Furthermore, the system also includes:

[0075] like Figure 3 and Figure 4 The following are pin diagrams of the first Type-C socket and the second Type-C socket.

[0076] Combination Figures 2-4 As shown, the input pins include:

[0077] Ground (GND) pin, power supply (VBUS) pin, charging (CC) pin, data transmission pin, and high-speed data transmission pin;

[0081] Based on the pin level information, determine whether the pin level of GND pin, VBUS pin, CC pin, D+ pin, D- pin, TX1+ pin, TX1- pin, RX1+ pin, and RX1- pin is high or low.

[0082] If at least one of the GND and VBUS pins is high, then the Type-C cable under test does not support all cable functions.

[0083] If the pin levels of GND and VBUS are both low, then the support for charging function is determined by the pin level of CC, the support for data transmission function is determined by the D+ and D- pins, and the support for video transmission function is determined by the TX1+, TX1-, RX1+, and RX1- pins.

[0084] If the CC pin is at a high level, it is determined that the Type-C cable under test does not support charging.

[0085] If the CC pin is at a low level, it is determined that the Type-C cable under test supports charging.

[0087] If both the D+ and D- pins are low, it is determined that the Type-C cable under test supports data transmission.

[0088] If at least one of the TX1+ pin, TX1- pin, RX1+ pin, and RX1- pin is high, then the Type-C cable under test does not support video transmission.

[0089] If the TX1+, TX1-, RX1+, and RX1- pins are all at a low level, then the Type-C cable under test is confirmed to support video transmission.

[0090] Combination Figure 2 As shown, the LED light control module includes:

[0091] First MOSFET Q1, second MOSFET Q2, and third MOSFET Q3;

[0092] The gate G of the first MOSFET Q1 is connected to the P1 pin of the MCU, the drain D is connected to the LED1 corresponding to the video transmission function, and the source S is grounded.

[0094] The gate (G) of the third MOSFET Q3 is connected to the P3 pin of the MCU, the drain (D) is connected to the LED3 corresponding to the charging function, and the source (S) is grounded.

[0095] Based on the description of the above embodiments, after determining whether the cable function can support it, the LED light is controlled to display. The specific process is as follows:

[0096] Based on the fact that the Type-C cable under test supports video transmission, the corresponding LED control signal for LED1 is generated as P1 pin is high level; this drives the first MOSFET Q1 to conduct, causing LED1 to light up.

[0097] Since the Type-C cable under test does not support video transmission, the corresponding LED control signal for LED1 is generated as follows: P1 pin is low; the first MOSFET Q1 is not turned on, thus turning off LED1.

[0098] Based on the fact that the Type-C cable under test supports data transmission, the corresponding LED control signal for LED2 is generated as P2 pin is high level; this drives the second MOSFET Q2 to conduct, causing LED2 to light up.

[0099] Since the Type-C cable under test does not support data transmission, the corresponding LED control signal for LED2 is generated as follows: P2 pin is low; the second MOSFET Q2 is not turned on, thus turning off LED2.

[0100] Based on the fact that the Type-C cable under test supports charging, the corresponding LED control signal for LED3 is generated as P3 pin is high level; this drives the third MOSFET Q3 to conduct, causing LED3 to light up.

[0101] Since the Type-C cable under test does not support charging, the corresponding LED control signal for LED3 is generated as follows: P3 pin is low; the third MOSFET Q3 is not turned on, causing LED3 to turn off.

[0102] Therefore, users can determine the cable functions supported by the Type-C cable by directly observing the lighting and turning off of LED1, LED2, and LED3.

[0103] Based on the above embodiments, before performing functional testing of the Type-C cable, it is also necessary to determine whether the Type-C cable is inserted. Preferably, in some embodiments of the present invention, the MCU microcontroller detects in real time whether the Type-C cable to be tested is inserted, including:

[0104] When the MCU microcontroller determines that the Type-C cable is not inserted, it indicates that all pin levels are high based on the Type-C interface signals received from the input pins.

[0105] When the Type-C cable is not plugged in, the MCU outputs a low level to the P1, P2 and P3 pins.

[0106] In summary Figure 1 and Figure 2 In the embodiments shown, and in some embodiments of the present invention, the system further includes:

[0107] The main unit power supply module VBAT and the switch control module SW;

[0108] The switch control module SW is connected between the host power supply module VBAT and the power interface of the MCU microcontroller;

[0109] When it is necessary to perform cable function testing on the Type-C cable to be tested, the control switch module SW is turned on, so that the host power supply module VBAT supplies power to the MCU microcontroller, and the MCU microcontroller is initialized.

When the Type-C cable to be tested is inserted into the first Type-C socket 101 or the second Type-C socket 102, the MCU microcontroller 103 receives the Type-C interface signal through its input pins. It determines the pin level information of all pins based on the Type-C interface signal. Based on the pin level information, it determines whether the Type-C cable supports a specific cable function. Based on whether the cable function is supported, it generates an LED control signal for the corresponding LED. The LED control signal is sent to the LED control module 104. The LED control module 104 controls the corresponding LED to turn on or off according to the LED control signal.
