[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] Currently, data is usually transmitted between different electronic devices with the help of a card reader. For example, data on a camera is transmitted to a mobile phone or a computer via a card reader.

[0025] However, when the card reader in the related art transmits data between two different electronic devices, the data needs to be first read into the storage card in the card reader and then transmitted to the other electronic device, which results in a cumbersome data transmission process and poor transmission efficiency.

[0026] In order to solve the above technical problems, the present disclosure provides a card reader data transmission system applied to a card reader, in which a first bidirectional interface and a second bidirectional interface are arranged in the card reader data transmission system, and the first bidirectional interface and the second bidirectional interface can both receive and send data. When the first bidirectional interface is connected to a first external device and the second bidirectional interface is connected to a second external device, the card reader data transmission system can not only enable the first external device and the second external device to directly perform bidirectional data transmission through a data reading module, but also data transmission does not need to pass through a data storage module, thereby effectively improving the transmission efficiency; the card reader data transmission system can also enable the first external device to perform bidirectional transmission with the second external device and the data storage module through the data reading module, so that the data storage module can store the transmitted data, avoiding data loss caused by the user accidentally deleting the data of the first external device and the second external device, thereby improving the reliability of data transmission.

[0027] Combination Figure 1 An exemplary embodiment of the present disclosure provides a card reader data transmission system, which is applied to a card reader. The card reader data transmission system includes a first bidirectional interface 5, a second bidirectional interface 6, a data storage module 3, and a data reading module 2. Exemplarily, the first bidirectional interface 5 can be, for example, a USB interface, a Type-C interface, a Lightning interface, etc., and the second bidirectional interface 6 can also be, for example, a USB interface, a Type-C interface, a Lightning interface, etc. The specific forms of the first bidirectional interface 5 and the second bidirectional interface 6 can be set according to needs, and no specific restrictions are made here.

[0028] The first bidirectional interface 5 and the second bidirectional interface 6 can both receive and send data. The data reading module 2 is connected to the first bidirectional interface 5, the second bidirectional interface 6 and the data storage module 3 respectively.

[0029] The card reader data transmission system is configured such that when the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, the first external device 1 and the second external device 4 and / or the data storage module 3 perform data transmission through the data reading module 2. Exemplarily, when the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, the card reader data transmission system can enable the first external device 1 to perform bidirectional data transmission only with the second external device 4 through the data reading module 2, can also enable the first external device 1 to perform bidirectional data transmission only with the data storage module 3 through the data reading module 2, and can also enable the first external device 1 to perform bidirectional data transmission with the second external device 4 and the data storage module 3 through the data reading module 2.

[0030] With such a setting, the card reader data transmission system can not only enable bidirectional data transmission between the first external device 1 and the second external device 4 directly through the data reading module 2, but also eliminate the need for data transmission through the data storage module 3, thereby effectively improving the transmission efficiency.

[0031] The card reader data transmission system can also enable the first external device 1 to perform two-way data transmission with the data storage module 3 only through the data reading module 2, so that the data of the first external device 1 can be stored in the data storage module 3. In the event that the user accidentally deletes the data of the first external device 1, the data can be extracted from the card reader data storage module 3, thereby effectively improving the reliability of data transmission.

[0032] The card reader data transmission system can also enable the first external device 1 to perform bidirectional data transmission with the second external device 4 and the data storage module 3 through the data reading module 2. For example, the data of the first external device 1 is firstly transmitted to the data storage module 3, and then the data in the data storage module 3 is transmitted to the second external device 4, or the data of the second external device 4 is firstly transmitted to the data storage module 3, and then the data in the data storage module 3 is transmitted to the first external device 1. In this way, in the case where the user accidentally deletes the data of the first external device 1 and the second external device 4, the data can be extracted from the card reader data storage module 3, thereby effectively improving the reliability of data transmission. At the same time, in the case of data transmission interruption, data transmission can also be performed by only connecting the first external device 1 and the data storage module 3 or only connecting the second external device 4 and the data storage module 3, thereby effectively reducing the complexity of data transmission.

[0033] In one embodiment, the data reading module 2 includes an MCU. It should be noted that an MCU (Microcontroller Unit) is also called a single-chip microcomputer, which appropriately reduces the frequency and specifications of a central processing unit (CPU), and integrates peripheral interfaces such as memory, timer, USB, A / D conversion, UART, PLC, DMA, and even LCD drive circuits on a single chip to form a chip-level computer, which performs different combination controls for different application scenarios.

[0034] When the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, or the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is not connected to the second external device 4, or the first bidirectional interface 5 is not connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, bidirectional data transmission between the first external device 1, the second external device 4 and / or the data storage module 3 is controlled by MCU, which can effectively improve the accuracy of control, thereby further ensuring the reliability of data transmission.

[0035] The data storage module 3 includes a memory card. It should be noted that a memory card is also called a flash memory card, which is a data storage medium in the form of a small card. It is generally used as a storage medium in small digital products such as digital cameras, handheld computers, MP3s, etc., for storing electronic information such as data. The memory card is mainly composed of a main control chip and a flash memory chip, including SD cards, MicroSD cards, CF cards and other types. Among them, MicroSD cards are also called TF cards, which are commonly used to expand the capacity of devices such as mobile phones and tablets.

[0036] By using a memory card as the data storage module 3, compared with traditional storage devices such as a USB flash drive, it has a higher cost-performance ratio and effectively increases the storage capacity, thereby effectively improving the user experience.

[0037] In one embodiment, the first bidirectional interface 5 includes a first data terminal 51, and the second bidirectional interface 6 includes a second data terminal 61. When the data reading module 2 is electrically connected to the first data terminal 51 and the second data terminal 61, data can be transmitted between the first data terminal 51 and the second data terminal 61, thereby realizing bidirectional data transmission between the first external device 1 and the second external device 4. With such a configuration, on the one hand, the first external device 1 and the second external device 4 do not need to pass through the data storage module 3 during data transmission, thereby effectively improving the transmission efficiency. On the other hand, the structure of the card reader data transmission system is simple and easy to process.

[0038] In one embodiment, when the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, the card reader data transmission system can also enable power transmission between the first external device 1 and the second external device 4. Exemplarily, when the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, the first external device 1 can charge the second external device 4, or the second external device 4 can charge the first external device 1. With such a design, the charging of the first external device 1 or the second external device 4 can be achieved without the aid of other charging devices, thereby effectively improving the convenience of charging the first external device 1 or the second external device 4. In addition, the timeliness of charging the first external device 1 or the second external device 4 can also be improved, avoiding the interruption of data transmission caused by the shutdown of the first external device 1 or the second external device 4 due to low power, thereby further improving the reliability of data transmission.

[0039] In one embodiment, the first bidirectional interface 5 includes a first power supply terminal and a first ground terminal, and the second bidirectional interface 6 includes a second power supply terminal and a second ground terminal. When the first bidirectional interface 5 is connected to the first external device 1, and the second bidirectional interface 6 is connected to the second external device 4, the data reading module 2 can control the first power supply terminal to be electrically connected to the second power supply terminal, and the first ground terminal to be connected to the second ground terminal, so that the first power supply terminal, the second power supply terminal, the first ground terminal, and the second ground terminal form a charging circuit, thereby realizing the power transmission between the first external device 1 and the second external device 4. With such a setting form, the structure of the card reader data transmission system is simple and easy to process.

[0040] In one embodiment, when the second bidirectional interface 6 is connected to the second external device 4 and the first bidirectional interface 5 is not connected to the first external device 1, at this time, the card reader data transmission system enables the second external device 4 and the data storage module 3 to perform bidirectional data transmission through the data reading module 2, that is, the data reading module 2 controls the bidirectional data transmission between the second external device 4 and the data storage module 3. In this way, not only the complexity of data transmission is reduced, the data of the second external device 4 can be stored in the data storage module 3, but also the subsequent extraction of data is convenient.

[0041] In one embodiment, the first bidirectional interface 5 includes a spring pin connector. It should be noted that the spring pin connector is a connector that uses an elastic metal spring and a contact pin for connection. Exemplarily, the spring pin connector includes a plurality of spring pins or springs as connection terminals, which can be abutted against the data transmission end of the first external device 1. When the connection terminal is connected to the data transmission end of the first external device 1, the electrical connection between the first bidirectional interface 5 and the first external device 1 can be achieved. With such a setting, the connection convenience between the first bidirectional interface 5 and the first external device 1 can be effectively improved, thereby further improving the user experience.

[0042] In one embodiment, the second bidirectional interface 6 is a USB interface. Since many electronic devices use USB interfaces, the USB interface is used as the second bidirectional interface 6 to improve the convenience of connection between the second external device 4 and the second bidirectional interface 6.

[0043] In another embodiment, the second bidirectional interface 6 is a lightning interface, which can also meet the needs of users to achieve the connection between the second external device 4 and the second bidirectional interface 6.

[0044] In one embodiment, the second bidirectional interface 6 is provided with multiple, for example, 2, 3, etc., and different second bidirectional interfaces 6 have different interface types. Exemplarily, the second bidirectional interface 6 is provided with three, and the interface types of the three second bidirectional interfaces 6 are respectively a USB interface, a lightning interface, and a Type-C interface. Such a setting form effectively improves the use flexibility of the second bidirectional interface 6, can meet the different needs of users, and further improves the user experience.

[0045] In one embodiment, when the second external device 4 is an electronic device with special characteristics, such as a series of mobile terminals of Apple Inc. in the United States, a communication authentication chip is provided on the second bidirectional interface 6 for authenticating the connection with the second external device 4 when connecting to the second external device 4. The communication authentication chip can be, for example, an MFi authentication chip, which can effectively ensure that data can be transmitted between the second external device 4 and the first external device 1 and / or the data storage module 3, thereby improving the reliability of data transmission.

[0046] An exemplary embodiment of the present disclosure provides a card reader, the card reader comprising the card reader data transmission system as described above. Figure 1 The above-mentioned card reader data transmission system includes a first bidirectional interface 5, a second bidirectional interface 6, a data storage module 3, and a data reading module 2. The first bidirectional interface 5 and the second bidirectional interface 6 can both receive and send data. The data reading module 2 is connected to the first bidirectional interface 5, the second bidirectional interface 6, and the data storage module 3 respectively.

[0047] The card reader data transmission system is configured such that when the first bidirectional interface 5 is connected to the first external device 1 and the second bidirectional interface 6 is connected to the second external device 4, the first external device 1 and the second external device 4 and / or the data storage module 3 perform data transmission through the data reading module 2. With such a configuration, the card reader data transmission system can not only enable the first external device 1 and the second external device 4 to perform data transmission directly through the data reading module 2, but also enable data transmission without passing through the data storage module 3, thereby effectively improving the transmission efficiency.

[0048] The card reader data transmission system can also enable the first external device 1 to perform two-way data transmission with the data storage module 3 only through the data reading module 2, so that the data of the first external device 1 can be stored in the data storage module 3. In the event that the user accidentally deletes the data of the first external device 1, the data can be extracted from the card reader data storage module 3, thereby effectively improving the reliability of data transmission.

[0049] The card reader data transmission system can also enable the first external device 1 to perform bidirectional data transmission with the second external device 4 and the data storage module 3 through the data reading module 2. For example, the data of the first external device 1 is firstly transmitted to the data storage module 3, and then the data in the data storage module 3 is transmitted to the second external device 4, or the data of the second external device 4 is firstly transmitted to the data storage module 3, and then the data in the data storage module 3 is transmitted to the first external device 1. In this way, in the case where the user accidentally deletes the data of the first external device 1 and the second external device 4, the data can be extracted from the card reader data storage module 3, thereby effectively improving the reliability of data transmission. At the same time, in the case of data transmission interruption, data transmission can also be performed by only connecting the first external device 1 and the data storage module 3 or only connecting the second external device 4 and the data storage module 3, thereby effectively reducing the complexity of data transmission.
