[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Please refer to Figure 1 and Figure 2 , In an embodiment of the utility model, a dual-screen information disclosure system includes an Internet of Things communication module, a main unit module connected to the Internet of Things communication module, a screen display module connected to the main unit module, and an operation detection unit connected to the screen display module;

[0021] In this embodiment, the Internet of Things communication module is connected between the main unit module and the operation detection unit, and the main unit module and the operation detection unit are connected to each other;

[0022] In this embodiment, the screen display module includes a first display unit connected to the main unit module, and a second display unit connected to the main unit module;

[0023] In this embodiment, the main unit module receives the display information of the Internet of Things communication module and transmits it to the first display unit and the second display unit for display, and collects the device transition information by running the detection unit.

[0024] In this embodiment, the main unit module is connected to a power source for converting 220V AC power into 12V DC power.

[0025] In this embodiment, the power supply module includes a BUCK converter, a USB power supply module connected to the BUCK converter, and a system power supply module connected to the BUCK converter.

[0026] In this embodiment, the main unit module includes a CPU module, a power-on timing unit connected to the power supply module, and a video external unit connected between the CPU module and the screen display module.

[0027] In this embodiment, the power-on timing unit includes a DC converter, a low voltage dropout linear regulator, and a codec.

[0028] In a specific embodiment, a 220V AC power supply is connected, which is converted into a 12V DC power supply by a power supply module to power the main unit module and the screen display module of the device. The main unit module (central processing unit) is connected to two screen display modules, and the main unit module sets the layout and content of the two screen display modules. At the same time, the main unit module is connected to the Internet of Things communication module, and a network interface is reserved to realize network communication, which is used to receive information release content and realize remote information release. The main unit module is also connected to the operation detection unit to monitor the operation status of the device in real time.

[0029] Working Principle: The device first introduces power from a 12V DC power supply and converts the voltage to the voltage level required by the internal core device through an external input transformer unit. The input unit mainly includes three BUCK converters (DC-DC converters), which are used to reduce the voltage to 3.3V and 5V required by the system and power the USB interface. The design of this unit adopts a sophisticated feedback mechanism and input and output circuit design to dynamically adjust the output voltage to ensure high stability of the power supply.

[0030] The power supply part of the system is responsible for driving the power-on timing unit, which consists of four key parts: first, four BUCK converters further reduce the supply voltage to power the CPU; second, the linear low-voltage regulator further stabilizes the output voltage to meet the CPU's high sensitivity to power quality; the third part is the management module, which is responsible for the signal output of the power-on timing unit and communicates with the CPU through the I2C bus; finally, the codec module provides a back-end interface for testers to debug, and supports the installation of speakers and microphones to expand device functions.

[0031] Subsequently, the system's operation detection unit is responsible for monitoring the operating status of each module. If an abnormal operation is detected, a reset signal will be sent to reset the system and communicate with the CPU via UART in real time to ensure stable operation of the system.

[0032] Finally, if Figure 3 As shown in the figure, the working principle diagram of the dual-screen information disclosure system is that the CPU processes and sends out MIPI signals, which are converted into LVDS signals through the video external unit and then transmitted to the LCD display unit to display the content. The video external unit and the CPU also communicate through I2C to ensure the accuracy and synchronization of signal conversion.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
