The second scheme adopts the equipment end to extract APP through NFC transmission data to extract the mobile phone, and the equipment end and the mobile phone are directly connected through WiFi to be in communication connection. After the user has transmitted the file through NFC, need the user to go the file management and look for data and draw APP, manually go to install APP, still need manually to open APP after the installation is accomplished, the extraction process needs the user to click the operation many times, degree of automation is lower, influences extraction efficiency, and open the hot spot equipment that wiFi directly links very power consumptively, can shorten the time of endurance who draws equipment like this, be unfavorable for removing the development of drawing work.

In conclusion, the existing USB wired extraction scheme has the defects that the USB driver is failed to be installed and the USB port is easily damaged; the existing wireless extraction mode is too dependent on third-party software, and has the defect of more limitation; the existing NFC and WiFi direct connection mode has the defects of more times of manual participation, power consumption of equipment and the like.

fig. 4 is a schematic diagram of a data extraction terminal, i.e., a device side and a mobile phone side, implementing wireless connection by using an ADB TCP/IP connection manner. As shown in fig. 4, the data extraction terminal includes an ADB Client (ADB Client) and an ADB Server (ADB Server), and the ADB Client establishes a connection with the ADB Server through a designated port. In one implementation, after the ADB Server at the device side is started, the ADB Client binds to the 5037 port of the device, and connects, i.e., dialogues, with the ADB Server by using 5037.

In fig. 4, the adbd Daemon is a process running in the background of the Android device, that is, a Daemon process, and the process monitors one of the USB connection and the network connection according to the configuration of the mobile phone when the server is started.

The data extraction terminal may provide the user with the functionality of data extraction policy setting and/or selection, for example, by way of a data extraction service module or component. In a specific implementation, after a data extraction APP is started, a corresponding strategy of data extraction is actively acquired from a data extraction service component; after the data extraction service module sends a data extraction strategy to the mobile phone, after a data extraction APP of the mobile phone obtains the strategy, information on the mobile phone is gradually obtained according to the received strategy; the data extraction APP pushes the acquired information to a data extraction service module, then whether the information needs to be acquired or not is judged, if yes, the information continues to be acquired, and if not, the information acquisition is finished; after the information acquisition is finished, the user may be prompted to delete the data extraction APP. If the user selects to delete the data extraction component such as APP, responding to the instruction of uninstalling the extraction application component in the target mobile phone, the data extraction terminal can uninstall the extraction application component such as APP through the established ADB TCP/IP connection.

When a plurality of target mobile phones are extracted, the data extraction terminals can establish ADB TCP/IP connection to realize wireless extraction by the method of the embodiment of the invention; and part of the target mobile phones can also establish ADB wired connection through the USB port. Under the condition that a plurality of target mobile phones exist, the data extraction terminal respectively establishes ADB connection with the plurality of target mobile phones through ADB remote connection commands, wherein after ADB TCP/IP connection and/or ADB USB connection are included, each target mobile phone establishing ADB connection with the data extraction terminal generates a unique serial number, and the data extraction terminal distinguishes different target mobile phones through the serial numbers. Specifically, a set of data protocols can be defined to simultaneously receive data information of multiple data extraction APPs, realize a multi-channel data extraction function, and be compatible with data extraction of a single USB wired mobile phone or a mobile storage medium.

By utilizing the established ADB TCP/IP connection, the data extraction terminal, namely the equipment end can directly use the ADB command to carry out operations such as transmission, installation, starting, unloading and the like on the data extraction component on the target mobile phone, without depending on third-party application, the limitation is small, the ADB remote operation mode can reduce the manual operation times of a user, and the automation degree and the extraction efficiency are high; and the operation is simple and convenient, which is very helpful for workers to move and work. In short, the ADB connection communication established between the data extraction terminal and the target mobile phone can be used for extracting one-click installation of the application, is convenient and fast, and avoids a plurality of manual operations required in the existing wireless extraction method.
