The first contact set comprises four contacts and can work in a serial communication mode and a USB communication mode at least. In the serial communication mode, the first contact of the first contact set is VBUS, the second contact is RX, the third contact is TX, and the fourth contact is GND, and in the USB communication mode, the first contact is still VBUS, the second contact is D-, the third contact is d+, and the fourth contact is still GND, see the first contact set in fig. 2A and the second contact set in fig. 2B.
Further, as shown in fig. 3, the mobile device further includes a selection switch connected to the CPU. The CPU controls the change of the communication mode of the first contact set through the switching of the high-low level control selection switch; and detecting whether the base is accessed or not when the communication mode is changed each time through the second contact or the third contact of the first contact set, and controlling the first near field communication module to identify the base when the base is accessed.
Referring to FIG. 4, the connection port of the CPU and the selection switch is set as a control port 1, and the connection port of the CPU and the normally-closed switch, namely the second contact (RX or D-) is set as a control port 2.

The base comprises a second body, a second contact set 21, a second near field communication module 22 and an MCU 23, wherein the second contact set 21 is arranged on the second body and is used for being connected with the first contact set 11 of the mobile device; the second near field communication module 22 is configured to send identification information of a current scene to a corresponding mobile device; the MCU 23 is connected to the second contact set 21, and is disposed in the second body, and configured to output, when it is detected that the second contact set 21 is successfully connected to the first contact set 11, identification information to a corresponding mobile device through the second near field communication module 22, so that the mobile device obtains a current scene, and output display content corresponding to the identification information.
The MCU is also used for supplying power to the mobile device through the second contact set when the second contact set is successfully connected with the first contact set and the attribute of the contact of the second contact set is an electrical appliance attribute contact in consideration of power consumption in the using process of the mobile device, so that the mobile device can always work during the connection with the base. The voltage output by the power supply module of the base can be directly 5V, and can be directly supplied to the mobile equipment at the moment, or can be lower than 5V, such as 3.7V, and the voltage output by the power supply module is boosted to 5V through the conversion module at the moment.
In order to improve the safety of charging, the base of the embodiment starts to supply power only when successful connection with the mobile device is detected. For example, by default, the base TX is set to an IO port state, and when a low level hold is detected, it is considered that a mobile device is connected, and at this time, the power supply switch is turned on to supply power to the mobile device, see fig. 6; if the low level is not detected, the signal is switched to the USB state, whether the mobile equipment is accessed is confirmed, and if the mobile equipment is accessed, a power supply switch is turned on to supply power to the intelligent screen. If the access of the mobile equipment is not detected in both states, continuing to patrol the mobile equipment between the two states until the access of the mobile equipment is detected, and starting a power supply module to supply power for the mobile equipment when the access of the mobile equipment is detected.
In order to adapt to different mobile devices, the second contact set of the present embodiment may perform data transmission with the mobile device at least through one of a serial communication mode and a USB communication mode. The MCU circularly detects whether the mobile equipment is accessed in the current communication mode or not in real time by detecting whether the level of a contact point used for data transmission in the second contact point group is a preset threshold value, and if so, the MCU outputs identification information of the current scene to the corresponding mobile equipment through the second near field communication module so as to enable the mobile equipment to acquire the current scene and output display content corresponding to the current scene.
For serial communication mode, the first contact of the second contact set corresponds to VBUS, the second contact corresponds to RX, the third contact corresponds to TX, and the fourth contact corresponds to GND; for the USB communication mode, the first contact of the second contact set corresponds to VBUS, the second contact corresponds to D-, the second contact set corresponds to D+, and the fourth contact set corresponds to GND. Wherein for either communication mode, the second contact and the third contact are used for data transmission.
The identification information of the base is preferably set in the MCU, after the mobile device and the base are successfully connected, the MCU starts the corresponding second near field communication module, and the identification information of the MCU is sent to the first near field communication module of the mobile device through the second near field communication module. In order to ensure that the identification information of the base corresponds to the scene where the base is located, the embodiment preferably enables the identification information corresponding to the base in the inactive state to contain the inactive information. After the first near field communication module of the mobile device establishes communication with the second near field communication module of the base, the first near field communication module of the mobile device acquires the identification information of the base and sends the identification information to the CPU, if the CPU analyzes the combined identification information and finds that the combined identification information contains an unactivated signal, a configuration interface is output, so that a user configures a scene of the base through the configuration interface, and after receiving configuration information input or selected by the user, the corresponding identification information is written into the MCU of the current base, thereby ensuring that the base corresponds to the scene of the base one by one.

The contacts of the second contact set are convex, and the contacts of the first contact set are concave, so that the contacts in the first contact set of the mobile device are inserted into the contacts of the second contact set of the base when the scene system is used.
According to the technical scheme of the base provided by the embodiment of the invention, when the MCU of the base detects that the second contact set is successfully connected with the first contact set, the identification information is output to the corresponding mobile equipment through the second near field communication module, so that the mobile equipment acquires the current scene and outputs the display content corresponding to the identification information. The base is matched with corresponding mobile equipment, so that universality of the mobile equipment in different scenes is improved, the purpose that household appliances and furniture in different scenes share one mobile equipment is achieved, and a display screen is not required to be configured for each household appliance and furniture.
