As shown in fig. 1, the portable wireless SD card reader includes a wireless communication module, an operation module, a power module, a USB interface, an indicator light, and the like.
The wireless communication module is used for establishing wireless connection with the terminal equipment; the operation module is connected with the wireless communication module and used for connecting and receiving an operation instruction sent by the terminal equipment in a wireless communication mode, operating the SD card according to the operation instruction and providing wireless communication for sending operation structure information to the terminal equipment. In this example, the terminal device refers to an electronic device with a wireless communication function, such as a mobile phone, a tablet Computer, a Personal Computer (PC), and so on. When the portable wireless SD card reader is in wireless connection with the terminal equipment, the user sends an operation instruction to the operation module through the wireless connection by using the terminal equipment. Correspondingly, the operation module operates the SD card according to the received operation instruction and sends the operation result to the terminal equipment through wireless connection.
The portable wireless SD card reader provided by the invention establishes wireless connection with the terminal equipment in a wireless communication mode, receives the operation instruction of the terminal equipment through the wireless connection and sends the operation result information to the terminal equipment, so that the card reader is more convenient to carry and use.
The Wireless communication module comprises a Wireless Fidelity (WIFI) module and a Bluetooth module. Usually, the terminal device mostly has a WIFI/bluetooth function, and in order to improve the universality of the portable wireless SD card reader, the wireless communication module needs to integrate the WIFI/bluetooth function, i.e. the wireless communication module includes two modules, namely a WIFI module and a bluetooth module, so that the portable wireless SD card reader can establish wireless connection with the terminal device through a WIFI/bluetooth mode.
The operation module comprises an SD card slot and a control circuit connected with the wireless communication module. The control circuit is used for receiving an operation instruction sent by the terminal equipment through wireless connection, operating the SD card inserted into the card slot according to the operation instruction, and sending operation result information to the terminal equipment through wireless connection. After the SD card is inserted into the card slot, the SD card is directly connected with the card slot through the metal electrode contact on the surface and then connected with the control circuit, so that the control circuit can operate the SD card inserted into the card slot according to the operation instruction.
The power module is connected with the operation module and the wireless communication module and used for increasing power for the operation module and the wireless communication module. The portable wireless SD card reader is internally provided with a power module which is used for providing power for circuits in the operation module and the wireless communication module.
