Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

1 is a flowchart of a method for controlling an intelligent interaction device according to an embodiment of the present application. The device includes: a processor, a electromagnetic screen and a electromagnetic screen control unit, a display screen and a display control unit, a sounding device, and a sounding device. The device control unit, as shown in FIG. 1, includes the following steps:

Step S102: The processor of the smart interaction device receives a power-on signal, and the power-on signal is used to trigger the activation of the smart interaction device.

Specifically, the above-mentioned intelligent interactive device, referred to as an all-in-one machine, combines functions such as computer and television, and is applied to fields such as education, teaching, business meetings, and commercial display, effectively improving the communication environment and improving the communication efficiency of the group. In the case that the smart interaction device is a smart interaction tablet, the processor of the smart interaction device may be one or more CPUs integrated in the device for controlling the operation of the smart interaction device.

The above-mentioned power-on signal may be a signal sent by the user to the device for triggering the smart interaction device to start.

Optionally, in the embodiment of the present application, the processor of the smart interaction device receives the power-on signal, which may be: a tact switch is disposed under the panel of the smart interaction device, and the user presses the tact switch, and the tact switch is closed to generate a rise. A valid trigger pulse along the active or falling edge, the processor of the intelligent interactive device starts power-on after receiving the trigger pulse.

Optionally, in the embodiment of the present application, the power-on signal is used to trigger the activation of the smart interaction device, and the user may also initiate an open command to the smart interaction device by using the mobile terminal in the same network as the smart interaction device, and the smart interaction device The power-on command is used as the power-on signal, and the power-on is started according to the power-on signal.

In an optional embodiment, the smart interaction device is used as an example, and the user controls the smart interaction tablet to start, and sends a power-on signal to the smart interaction tablet, that is, the power-on signal, and the processor of the intelligent interaction device passes. Receive and receive the power-on signal sent by the user, perform initialization operations, and enumerate external devices.

Step S104: The processor of the smart interaction device starts to power on the display screen and the display control unit, the sounding device, and the sounding device control unit.

Specifically, the smart interactive tablet is mostly used for scenes such as conferences or education, and therefore needs to have display and voice functions. Optionally, the image capturing and sound picking functions can also be provided, so correspondingly, the smart interactive device can also include a camera and a microphone.

In the above steps, when the processor of the smart interactive tablet is powered on, the display screen and the display control unit for realizing the display function, and the sounding device for realizing the sounding function and the sounding device control unit can be powered on. In addition, it is also possible to power on an external device of the smart interactive device other than the electromagnetic screen, such as a camera, a microphone, and the like.

Step S106, the processor of the smart interaction device starts a timer.

Specifically, the timer may be a timer of a processor of the smart interaction device, and is clocked by a clock signal inside the processor, and the timer is started when the processor of the smart interaction device is powered on.

Step S108, the timer completes the timing of the preset time, and the processor that triggers the smart interaction device starts to power on the electromagnetic screen control unit, wherein the electromagnetic screen control unit is used to drive the electromagnetic screen to operate.

Specifically, the preset time is a time when the device processor is powered on to a stable operation. For different types of smart interaction devices, they can correspond to different preset times.

The electromagnetic screen has an electromagnetic screen antenna board. When the electromagnetic pen is written on the electromagnetic screen, the electromagnetic wave emitted by the electromagnetic pen cuts the magnetic induction line to cause a change of the magnetic field, and the electromagnetic screen control unit is used to contact the electromagnetic pen and the electromagnetic screen according to the amount of the magnetic field change. The position is calculated to generate and display the corresponding writing handwriting to make the electromagnetic screen operate.

2 is a schematic diagram of an intelligent interaction tablet according to an embodiment of the present application. In an optional embodiment, as shown in FIG. 2, the device processor is a CPU (main board), and the CPU is controlled by a USB serial port and an electromagnetic screen. The units are connected. The CPU receives a power-on signal through the power board, thereby controlling an LCD (Liquid Crystal Display) and controlling the electromagnetic screen display unit. The electromagnetic screen display unit provides a clock signal to the MCU through a crystal externally connected to the MCU, converts the electromagnetic signal detected by the electromagnetic screen antenna board into an electrical signal through a transform circuit (Transform IC), and then receives a gain control signal (control signal AGC) sent by the MCU. After being amplified by the operational amplifier, it is sent to the MCU to complete the detection of the electromagnetic signal.

The electromagnetic screen control unit is powered up, so that the crystal of the electromagnetic screen control unit can be normally oscillated.

It should also be noted here that in order to solve the technical problem that the crystal probability of the electromagnetic screen control unit cannot be oscillated when the electromagnetic screen and the main board are powered on together, which may result in the electromagnetic screen being unusable, the electromagnetic screen control unit may also be The crystal connected to the controller is changed to an RC oscillator built into the controller, and the built-in oscillator provides a clock signal to the electromagnetic control unit. Since the RC oscillator is composed of a resistor and capacitor, the accuracy of the resistor and capacitor is the main factor affecting the oscillation frequency of the RC oscillator. When the capacitor or resistor is easily affected by external factors such as temperature and humidity, the frequency provided by the RC oscillator is not It is accurate enough to have a big impact on the function of the product.
