Problems solved by technology

Then the problem comes, once the battery of either party is not enough, you need to unplug the communication line connecting the two parties, and then plug in two chargers for charging. At this time, the business cannot be handled at the same time, and the progress will be delayed.
If business connection is required, you need to bring an extra set of equipment, which will also increase costs and wear and tear

Abstract

The invention provides a one-to-two type-c line and a master-slave device two-way charging method.The one-to-two type-c line comprises a first interface, a second interface, a power interface, a power line set and a data line set, the first interface is connected with one end of the power line set and one end of the data line set, the other end part of the data line group is connected to the second interface, and the other end part of the power line group is respectively connected with the second interface and the power interface; and the external power supply can be used for charging the two types-c devices at the same time when the two types-c devices are in normal communication.

Description

【Technical field】 [0001] The invention relates to a one-to-two type-c line and a two-way charging method for master and slave devices. 【Background technique】 [0002] In the past, service windows such as banks, hospitals, and securities companies mostly used wired counter-fixed terminal business equipment. With the rapid development of terminal equipment, more and more mobile and highly integrated handheld devices with batteries are used by more and more enterprises. [0003] At the same time, the combination of these mobile highly integrated handheld devices is also being used more and more. For example, banks and securities companies develop their own business programs and databases on commercial tablets, and provide external command interfaces. Large manufacturers design and provide industrial tablet devices with multifunctional bases, integrated password buttons, fingerprint readers, ID card recognition, magnetic stripe card swiping, liveness detection, and electromagne...
