If the external electronic device 60 is recognized as an electronic device 60 of the first device type (S12), the main control unit 30 will be controlled by the main control unit 30. The mode is switched to the slave mode (S13), and the external electronic device 60 of the first device type is switched from the slave mode to the master mode. The main control unit 30 starts to execute the first transmission communication protocol (S14).

The main control unit 30 begins to execute the third transmission protocol (S21). At this time, if it is determined that the external electronic device 60 issues a command, the entire data storage unit 50 is opened. The data can be freely accessed by the external electronic device 60 (S22). If the main control unit 30 recognizes that the external electronic device 60 is not the first to third default device types (not limited to these three device types), the device recognition is ended (S23). That is to say, the main control unit 30 can establish a data transmission path between the external electronic device 60 and the first or second data storage areas 51 and 52 of the data storage unit 50 according to the first and second device types; or it can establish a data transmission path according to the first and second device types; Or the second device type can establish a data transmission path between the external electronic device 60 and another external electronic device 60; or the main control unit 30 can establish a data transmission path between the external electronic device 60 and the data storage unit 50 according to the third device type. path.

As shown in FIG. 5 , when the main control unit 30 recognizes that the external electronic device plugged into one of the interface ports is an Apple mobile phone (iPhone 11), it will recognize it as the first device type and obtain its device number (such as N11). , if this external electronic device issues a data backup command request, it will divide a sub-storage area 511 in the first data storage area 51 according to its device number, and store the data for backup in its corresponding sub-storage area 511; at the same time, Processing, if the external electronic device in the other interface port is an Apple tablet (iPad Pro), it will also be recognized as the first device type, but its device number (such as N12) is different, so its device number will be used in the first data The storage area 51 is divided into a sub-storage area 512, and the data for backup is stored in the corresponding sub-storage area 512.

When the main control unit 30 determines that the external electronic device 60 that issues the instruction is the second device type according to step (a2), and the instruction request in step (b2) is for data backup, the second transmission protocol is used.

In this transmission mode, the master control unit 30 is preset in the master mode, and the electronic device identified as the second device type is in the slave mode. As shown in Figure 5, when the main control unit 30 recognizes that the external electronic device plugged into one of the interface ports is an Android phone or tablet, it will recognize it as a second device type and obtain its device number (such as N21). If the external electronic device 60 issues a data backup command request, it will divide a sub-storage area 521 in the second data storage area 52 according to its device number, and store the data for backup in its corresponding sub-storage area 521.

When the main control unit 30 determines that the external electronic device 60 that issues the instruction is the third device type according to step (a2), and the instruction request in step (b2) is data access, the data storage unit 50 is opened. , and use the third transmission protocol to access data. In this transmission mode, the main control unit 30 switches from the master mode to the slave mode. The external electronic device 60 of the third device type is the master, and the present invention is the slave. The external electronic device 60 directly stores the data. All data storage areas of unit 50 are used for data access. In this embodiment, the master control unit 30 switches from the default master mode to the slave mode, and the external electronic device 60 identified as the third device type is in the master mode.
