BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0017] In the following description, example details are provided to provide a deeper understanding of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0018] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0019] In order to solve the above technical problems, this application provides a method for monitoring the performance of the wire material of the USB wired interconnection between the mobile terminal and the vehicle terminal. Figure 1 , including the following steps: Connect the vehicle terminal and the mobile terminal via a USB cable, and collect the number of plug-in and unplug-out times between the cable and the mobile terminal; Detect the transmission speed and current-carrying parameters of the wire, and generate a parameter report based on the number of plug-in and plug-out times. Compare the parameter report with the standard report preset in the database to generate an evaluation report.

[0020] By using data collected from the transmission speed and current-carrying parameters of the wire to form a parameter report, users can intuitively understand the parameters of the wire through the parameter report; further, the parameter report is compared with the standard report to form an evaluation report to intuitively inform the user of the aging condition of the wire and assist the user in making a decision on whether to replace the wire.

[0021] Regarding the performance change of the cable, it can be understood that as the number of plugging and unplugging increases, dust accumulation and oxidation on the metal contacts will affect the charging speed and data. Based on real life, most users are equipped with separate cables in their vehicles. Therefore, in the specific solution, the steps for collecting the number of plugging and unplugging are as follows: Get the number of the cable charging chip and create a unique cable ID based on the number. When the number is obtained again, the number of connections corresponding to the detection cable ID is the number of plug-in and unplug times. It is not difficult to understand that the chip carried by the cable has a unique number. Therefore, a unique cable ID can be generated based on the uniqueness of the number. Then, the number of connections of the cable ID is collected and counted, and the corresponding number is recorded as the number of plug-in and unplug times. In a specific solution, detecting the transmission speed of the acquisition wire includes the following steps: The mobile terminal generates a virtual instruction and records the generation time of the virtual instruction; The vehicle terminal responds to the virtual command to generate a template animation; the template animation plays and displays the user information transmitted by the mobile terminal; the end time of the template animation is collected as the end time; the ratio between the duration of the template animation and the duration from the generation time to the end time is calculated, and the ratio is used as one of the reference items in the parameter report; It is not difficult to understand that the scheme of this embodiment has a relevant order: time segments of generation time, module animation playback, and end time. The shorter the time from generation time to module animation playback, the faster the wire transmission speed. However, if the generation time and module animation playback time are collected separately as reference items, it is difficult to examine the continuous transmission capability of the wire. Therefore, it is necessary to rely on the vehicle terminal to continuously pass through the wire to load the user information of the mobile terminal. In the process of displaying the user information in sequence, it is convenient for the user to confirm his or her identity. If the wire data transmission is stable, it will not affect the playback time of the template animation. On the contrary, it will lead to an increase in the playback time of the template animation. Based on the above principle, the obtained ratio can better reflect the stability reference item of data transmission.

[0022] In a better solution, after calculating the ratio, it also includes: The video frames of the template animation playback duration are collected, and the actual frame curve is generated based on the video frames. The actual frame curve is compared with the standard curve of the template animation, and the comparison result is used as one of the reference items in the parameter report. It is not difficult to understand that if the continuous output performance of the wire cannot meet the demand, the video frame rate will fluctuate, and the change can be intuitively observed through the actual frame curve. That is, when the data transmission of the wire is unstable, the fluctuation of the actual frame curve is also relatively large. It can be seen that the comparison result obtained by combining with the standard curve of the template animation can better reflect the reference item of data transmission stability.

[0023] In the specific solution, the acquisition of current parameters includes: Match the charging protocol, collect the actual output current of the charging state, compare the actual output current with the current corresponding to the charging protocol to obtain the current-carrying ratio, compare the current-carrying ratio with the preset standard ratio, and use the comparison result as one of the reference items in the parameter report. It is not difficult to understand that the charging protocol is matched first and then the expected current is determined. When the output current of the wire cannot reach the expected current, it can be determined that the charging speed cannot meet expectations, and the user is prompted to replace the wire.

[0024] Also provided is a wire performance monitoring system with USB wired interconnection between a mobile terminal and a vehicle terminal, comprising a vehicle terminal, a mobile terminal, a collection module, a processing module and a reporting module; The vehicle terminal and the mobile terminal are connected via a USB cable, and the acquisition module collects the number of plug-in and unplugging times between the cable and the mobile terminal; The calculation module detects the transmission speed and current-carrying parameters of the wire, and generates a parameter report based on the number of plug-in and plug-out times; the reporting module compares the parameter report with the standard report preset in the database to generate an evaluation report.

[0025] As an improved solution of the present invention, the steps for collecting the number of plug-in and plug-out times of the processing module are as follows: Get the number of the cable charging chip and create a unique cable ID based on the number. When the number is obtained again, the number of connections corresponding to the detection cable ID is the number of plug-in and unplug times.

[0026] As an improved solution of the present invention, the processing module detects the transmission speed of the wire rod including the following steps: The mobile terminal generates a virtual instruction and records the generation time of the virtual instruction; The vehicle terminal responds to the virtual instruction to generate a template animation, and the template animation plays and displays the user information transmitted by the mobile terminal; the control acquisition module acquires the end time of the template animation as the end time; The processing module calculates the ratio between the duration of the template animation and the duration from the generation time to the end time, and the reporting module uses the ratio as one of the reference items of the parameter report.

[0027] After calculating the ratio, it also includes: The acquisition module collects the video frames of the template animation's playback duration and generates an actual frame curve based on the video frames; the processing module compares the actual frame curve with the standard curve of the template animation, and the reporting module uses the comparison result as one of the reference items for the parameter report.

[0028] The processing module detects the current carrying parameters including: The vehicle terminal matches the charging protocol with the mobile terminal. The processing module controls the acquisition module to collect the actual output current of the charging status, and compares the actual output current with the current corresponding to the charging protocol to obtain the current-carrying ratio. The current-carrying ratio is then compared with the preset standard ratio. The reporting module uses the comparison result as one of the reference items for the parameter report.

[0029] It is not difficult to understand that the system is installed in the vehicle, and the above-mentioned detection method is implemented through the vehicle terminal, mobile terminal, acquisition module, processing module and reporting module, so as to detect the user's wires and inform the user to help the user understand the performance of the wires and make replacement decisions.

[0030] The advantages of the present invention are: By using data collected from the transmission speed and current-carrying parameters of the wire to form a parameter report, users can intuitively understand the parameters of the wire through the parameter report; further, the parameter report is compared with the standard report to form an evaluation report to intuitively inform the user of the aging condition of the wire and assist the user in making a decision on whether to replace the wire.
