The smart USB data cable provides a USB data cable that can display charging parameters, including a measurement circuit for measuring charging parameters and a display unit for displaying charging parameters. The input end of the measurement circuit is connected to the charger, and the output end of the measurement circuit is connected to the display unit respectively. and the device being charged.

During the charging process of electronic products, existing USB data cables on the market cannot allow consumers to intuitively see the charging status of the product. As the battery capacity of mobile phones and digital products continues to increase, the requirements for charging speed are getting higher and higher. Charging speed is directly determined by charging voltage and charging current. When the charging voltage can reach the rated value, the charging current will be larger and the charging speed will be faster. The charging current is not only determined by the charger, but also related to the current identification of the product being charged. The same charger, the same data cable, and different charging products will have different charging currents. In addition, there are many types of chargers on the market, and the quality of data cables also varies. The internal quality of products of various brands also varies. It is difficult for consumers to really choose the right charger and data cable, and there is no need to buy good and suitable products after spending a lot of money. The fundamental reason is that there is no way to distinguish and no standard of judgment. We can only judge based on appearance.

The technical problem to be solved by the smart USB data cable is to provide a method that can visually see the charging status of the product and select a suitable charger in order to solve the shortcomings of the existing technology that the charging status of the product cannot be visually seen and the appropriate charger cannot be selected. And a smart USB data cable that displays charging parameters. The technical solution adopted by this utility model to solve the technical problem is to construct an intelligent USB data line that can display charging parameters, including a measurement circuit for measuring charging parameters and a display unit for displaying charging parameters. The input end of the measurement circuit is connected to the charger. The output terminals of the measurement circuit are connected to the display unit and the charging device respectively. In the smart data line that can display charging parameters, the utility model also includes a wireless communication module connected to the output end of the measurement circuit for transmitting charging parameters to the charged device. In the smart data cable that can display charging parameters, interfaces are provided at both ends of the smart data cable. The smart data cable that can display the charging parameters of the present invention can be a USB interface or an Apple-specific interface. In the smart data cable that can display charging parameters, the wireless transmission method of the wireless communication module is Bluetooth or wifi or audio transmission. In a smart data line capable of displaying charging parameters, the display unit is an LCD screen. In a smart USB data cable that can display charging parameters, the device being charged is a mobile phone, tablet, MP3 or MP4.

Implementing the smart USB data cable that can display charging parameters of the present invention has the following beneficial effects: due to the use of a measurement circuit and a display unit, the measurement circuit transmits the measured charging parameters to the display unit for display, and you can intuitively see what is being charged The charging status of the device and select an appropriate charger based on the charging status.
