[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In view of the above problems in the prior art, the present invention provides a cable detection device. Figure 1 This is a schematic diagram of the structure of the cable detection device provided by the present invention. Figure 1 As shown, the cable detection device includes: a controller, and a first interface socket, a second interface socket, a test signal source circuit and a power supply detection module, all of which are connected to the controller, wherein:

[0035] The first interface socket and the second interface socket are both connected to the cable to be tested, and the first interface socket is used to generate a pin detection signal corresponding to each pin in the first interface socket based on the pin control signal of the controller;

[0036] The controller is used to determine the pin status of the cable under test based on the pin detection signal received by the second interface socket; the controller is also used to generate a target function enable signal based on the pin status of the cable under test; the target function enable signal includes a data transmission enable signal corresponding to the test signal source circuit and / or a power supply enable signal corresponding to the power supply detection module;

[0037] The test signal source circuit is connected to the first interface socket and the second interface socket respectively; the test signal source circuit is used to generate a data transmission detection signal based on the data transmission enable signal;

[0038] The power supply detection module is connected to the first interface socket and the second interface socket respectively; the power supply detection module is used to generate a power supply detection signal based on the power supply enable signal.

[0039] Specifically, the first interface socket, the second interface socket, the test signal source circuit, and the power supply detection module are respectively connected to the controller. The first interface socket and the second interface socket are both connected to the cable to be tested. The cable to be tested can be a Type-C interface cable or other cable. This embodiment does not make specific limitations here. When the controller receives a user instruction and needs to perform pin detection, it will send a pin control signal to the first interface socket. The first interface socket generates a pin detection signal corresponding to each pin based on the pin control signal. The pin detection signal can be, for example, a voltage signal.

[0040] After the first interface socket generates a pin detection signal corresponding to each pin, each pin detection signal is transmitted along the cable to be tested toward the second interface socket. Since the pins in the first interface socket correspond one to one to the pins in the second interface socket, after the pin detection signal of the corresponding pin passes through the cable to be tested, if the second interface socket can receive the pin detection signal, it indicates that the cable to be tested has a pin corresponding to the pin detection signal. If the second interface socket does not receive the pin detection signal, the cable to be tested does not include the pin corresponding to the pin detection signal. The controller can determine the pin status of the cable to be tested based on the pin detection signal received by the second interface socket. The controller can determine the pin status of the cable to be tested based on all the pin detection signals that the second interface socket can receive, and the pin status of the cable to be tested can further indicate the detectable type of the cable to be tested. After determining the pin status of the cable to be tested, the controller can also be used to generate a target function enable signal based on the pin status of the cable to be tested, and the target function enable signal includes a data transmission enable signal corresponding to the test signal source circuit and / or a power supply enable signal corresponding to the power supply detection module. The type of the target function enable signal indicates what kind of test is performed on the cable under test. For example, the data transmission enable signal indicates that the data transmission specification test is performed on the cable under test, and the power supply enable signal indicates that the power supply specification test is performed on the cable under test.

[0041] The test signal source circuit is respectively connected to the first interface socket and the second interface socket. After the controller generates a data transmission enable signal, the test signal source circuit can be used to generate a data transmission detection signal based on the data transmission enable signal. The data transmission detection signal represents the detection result of the data transmission specification detection of the cable to be tested.

[0042] The power supply detection module is respectively connected to the first interface socket and the second interface socket. After the controller generates a power supply enable signal, the power supply detection module can be used to generate a power supply detection signal based on the power supply enable signal. The power supply detection signal represents the detection result of the power supply specification detection of the cable to be tested.

[0043] In one embodiment, the test signal source circuit includes a signal source chip and a detection subcircuit, and the detection subcircuit includes a signal transmission interface RF1 and a signal transmission interface RF2;

[0044] The signal source chip is used to generate data transmission specification signals of different specifications based on the data transmission enable signal;

[0045] One end of the signal transmission interface RF1 is connected to the first signal path pin of the signal source chip, and the other end of the signal transmission interface RF1 is connected to the first interface socket. One end of the signal transmission interface RF2 is connected to the second signal path pin of the signal source chip, and the other end of the signal transmission interface RF2 is connected to the second interface socket.

[0046] Specifically, Figure 2 This is a schematic diagram of the structure of the test signal source circuit provided by the utility model. Figure 2 As shown, the test signal source circuit includes a signal source chip U1 and a detection sub-circuit, and the detection sub-circuit includes a signal transmission interface RF1 and a signal transmission interface RF2. Figure 2 GND represents ground. One end of the signal transmission interface RF1 is connected to the first signal path pin RFOUTA+ of the signal source chip, and the other end of the signal transmission interface RF1 is connected to the first interface female socket. One end of the signal transmission interface RF2 is connected to the second signal path pin RFOUTA- of the signal source chip, and the other end of the signal transmission interface RF2 is connected to the second interface female socket.

[0047] The signal source chip U1 is used to generate data transmission specification signals of different specifications based on the data transmission enable signal. On the basis of the above connection relationship, the data transmission specification signal can be sent by the signal source chip U1 from the first signal path pin RFOUTA+ to the signal transmission interface RF1, and then the data transmission specification signal is transmitted to the cable under test through the first interface socket. The cable under test may allow the data transmission specification signal of this specification to pass through, or may not allow the data transmission specification signal of this specification to pass through. If allowed, the data transmission specification signal of this specification is transmitted to the signal transmission interface RF2 through the second interface socket, and then returned to the second signal path pin RFOUTA- of the signal source chip U1. When the signal source chip receives the data transmission specification signal of this specification, it indicates that the cable under test supports the transmission data of this specification. It is easy to understand that when the signal source chip does not receive the data transmission specification signal of this specification, it indicates that the cable under test does not support the transmission data of this specification.

[0048] Among them, the data transmission enable signal includes a video transmission enable signal and a file transmission enable signal, and the data transmission specification signal includes a video transmission specification signal and a file transmission specification signal. Exemplarily, based on the pin status of the cable under test, the controller generates a video transmission enable signal requiring video transmission specification detection, and the signal source chip U1 generates video transmission specification signals of different specifications and traverses the transmission of video transmission specification signals from low specification to high specification. Ultimately, when the signal source chip receives a 720p data transmission specification signal and does not receive a 1080p data transmission specification signal, it indicates that the highest video transmission specification supported by the cable under test is 720p.

[0049] In the above embodiment, one end of the signal transmission interface RF1 is connected to the first signal path pin of the signal source chip, the other end of the signal transmission interface RF1 is connected to the first interface female socket, one end of the signal transmission interface RF2 is connected to the second signal path pin of the signal source chip, and the other end of the signal transmission interface RF2 is connected to the second interface female socket. This can simply complete the detection of the data transmission specifications of the cable to be tested, and the detection result will be more accurate.

[0052] Specifically, the detection subcircuit also includes a filter and shaping circuit, which is connected to the signal transmission interface RF1 and the signal transmission interface RF2, respectively. The filter and shaping circuit is used to generate data transmission filter signals corresponding to each data transmission specification signal. Each data transmission specification signal generated by the signal source chip passes through the filter and shaping circuit. After filtering and shaping each data transmission specification signal, the filter and shaping circuit obtains a data transmission filter signal, which is then transmitted to the signal transmission interface RF1. The data transmission filter signal received by the signal transmission interface RF2 passes through the filter and shaping circuit again. After filtering and shaping each data transmission filter signal, the filter and shaping circuit obtains each target data transmission filter signal. Each target data transmission filter signal is then transmitted to the second signal path pin RFOUTA- of the signal source chip.

[0053] In the above embodiment, the noise in the signal can be filtered out by the filtering and shaping circuit, thereby further improving the accuracy of the detection of the cable to be tested.

[0054] In one embodiment, Figure 2 As shown, the filtering and shaping circuit includes: inductor L1, inductor L2, capacitor C11, capacitor C12, capacitor C13, capacitor C14 and capacitor C15, wherein:

[0055] One end of the inductor L1 is connected to the first signal path pin of the signal source chip and one end of the capacitor C11 respectively, and the other end of the capacitor C11 is connected to one end of the signal transmission interface RF1;

[0056] One end of the inductor L2 is connected to the second signal path pin of the signal source chip and one end of the capacitor C12 respectively, and the other end of the capacitor C12 is connected to one end of the signal transmission interface RF2;

[0057] The capacitor C13, the capacitor C14 and the capacitor C15 are connected in parallel, and one end of the parallel connection is respectively connected to the other end of the inductor L1, the other end of the inductor L2 and the power supply, and the other end of the parallel connection is grounded.

[0058] In the above embodiment, the filtering and shaping function of the filtering and shaping circuit is realized by setting the inductor L1, the inductor L2, the capacitor C11, the capacitor C12, the capacitor C13, the capacitor C14 and the capacitor C15 and their respective connection relationships.

[0061] In the above embodiment, the check sub-circuit can ensure the correctness of the data transmission specification signal, thereby avoiding errors in the detection of the cable to be tested to a certain extent.

[0064] In the above embodiment, the setting of the clock subcircuit ensures the normal operation of the test signal source circuit.

Adjusting the size of the electrically controlled variable load can simulate the type and status of different receiving-end devices, and then the power supply voltage and current can be actually monitored to obtain the charging power of the PD protocol control chip in real time. By adjusting the resistance value of the electrically controlled variable load, the PD protocol control chip can be tricked into different power supply levels, and the power supply specifications supported by the PD protocol control chip, such as 9V2A and 20V3.25A, can be awakened respectively.

[0071] In the above embodiment, the PD protocol control chip and the electrically controlled variable load are respectively connected to the controller, so that the device of the utility model can accurately detect the power supply specifications of the cable to be tested.
