Description

The utility model relates to the field of data input-output subsystems, high-resolution information screens and is intended for use in ground wheeled and railroad transport.

A device installed in a vehicle is known (patent RU No. 2406107, G06F 3/00, H04N 7/18, G06F 17/30, publ. 10.12.2010). The AV device contains a connection block that is connected to an external device; a first control button that is used to start searching processing for portions of content stored in the external device; a content list acquiring unit that, when the first control button is operated, obtains from an external device a content list having a hierarchical structure according to which the content portions are classified as items; a storage unit in which the content list obtained by the content list acquiring unit is stored; a second control button that includes an operation controller that can be rotated and pressed, and when the operation controller is rotated, a content list item displayed on a predetermined portion of the display is selected, and when the operation controller is pressed, the display in the content list changes from the top level to the bottom level, and install the element; a third control button, which is used to change the displayed list of contents from the lower level to the upper level; and a light emission control unit that provides operating instructions for prompting the next operation by changing the light emission state of the second control button when the first control button is operated.

A device for displaying information for a vehicle is known (patent RU No. 2582542, G06F 3/00, B60R 16/02, publ. 04/27/2016). The technical result consists in the possibility of visual identification of the information of the details of the operation entered by the driver of the vehicle. The information display device for the vehicle comprises: an audio module installed in the vehicle and having an operation input module; a steering wheel switch for operating the audio module, the steering wheel switch being provided on the steering wheel of the vehicle; an instrument cluster having an instrument panel; and the dashboard displays operation detail information representing the operation details instructed to the audio unit by operation of the operation input unit or switch on the steering wheel.

A known system for controlling a touchscreen display in a vehicle (patent RU No. 2676043, G06F 3/01, G06F 3/041, B60K 37/00, publ. 25.12.2018). The system includes an electrode located throughout the touch screen display and a signal generator that generates an oscillating signal to create a potential difference between the finger and the electrode, resulting in an appropriate perceived texture when the finger is moved across the touch screen. The control circuit is configured to adjust at least the frequency or amplitude of the oscillating signal to change the perceived texture in accordance with the first and second modes when working with a graphical human-machine interface. The first mode uses a local texture map defined by the corresponding function icon selection areas on the touchscreen. The second mode uses a state texture map, which defines the perceived texture for each possible adjustable setting for the function icon that was selected for use in the first mode.

The disadvantages of the known technical solutions include limited functionality.

Display module ID-29-SR-G3 (https://www.vianova-tn.de/images/vianova/downloads/en/140916_CE_Displays%20Stretch_EN.pdf) is a display module of the previous generation, used in a multimedia complex for public transport.

The disadvantages of this solution are insufficient computing power, lack of audio outputs for informing passengers, insufficiently high resolution and dimensions of the matrix, as well as the lack of a built-in video camera for analyzing passenger behavior.

The technical objective of the claimed invention is to create a new information screen INFO for the purpose of embedding additional interfaces for audio information and video cameras.

The task is solved by the fact that the INFO information screen contains a housing, an LCD matrix for displaying an image, a controller in the form of a motherboard of its own design, an audio information subsystem, a video camera, a microphone and speakers for audio information. Unlike the prototype, it contains USB and MIPI-CSI interfaces for connecting cameras for video analytics, two audio output channels with a power of 10 W per channel, and a set of interfaces for connecting a matrix.

The utility model is illustrated by the following drawings.

Figure 1 shows the structure of the INFO information screen. Information screen INFO contains: case 1, LCD matrix 2, motherboard 3, video camera 4, microphone 5, speakers 6.

FIG. 2 shows a general view of the INFO information screen.

FIG. 3 is an outline drawing.

The INFO information screen is designed to work as part of the audio and video information system for passengers. The following systems are integrated into the information screen:

- Formation and output of the image;

- Audio information;

- Video surveillance and video analytics;

- Connections;

- Nutrition.

The main task of the information screen is to inform public transport passengers. With the help of the applied technologies and algorithms, it was possible to lay the possibility of a significant increase in the efficiency of its use. The audio information system allows you to duplicate important visual information or supplement it. The presence of a built-in microphone allows you to organize interaction with passengers. Using a video camera as part of an information screen will allow you to analyze the audience and evaluate the effectiveness of using content using computer vision.

Table 1 summarizes the main characteristics of the INFO information screen.
