Description

The present invention relates to human information systems and video recording systems.

The device is designed to inform people - third-party observers, by forming a static and / or dynamic image and / or video stream on the visible surface of a vehicle, mobile kiosk, store or other object on which a mobile information system is installed.

From the existing prior art known:

1) Mobile information system [1] (Invention patent RU 2659956), the disadvantage of this system is the video monitor, which is applied to the glass using a mechanism, strong heating of the device from exposure to direct sunlight, the inability to control the system remotely.

2) Mobile display [2] (Patent for invention RU 2671053), which is a multilayer structure with a plastic adhesive lens on the front side, which serves to fill the space between the display screen and the curved window of the vehicle (shop or kiosk), as well as for attaching the display to the window surface. The disadvantage of this device is the low manufacturability of the design, which requires the manufacture of a labor-intensive additional element (lens), the possibility of mounting only from the inside on the dismantled glass with the subsequent installation of glass, strong heating of the device from exposure to direct sunlight, as well as the possibility of installation only on glass or other translucent material. The design has low maintainability, the failure of one of the elements will require a complete replacement of the mobile display.

3) Video cameras that can be placed: inside the car under the rear window [3], outside the car on the roof [4], outside the car in the bumper, trunk lid, license plate frame, in the ceiling and so on [5]. The disadvantages of these technical solutions are the low data transfer rate from the video camera to the display, which manifests itself in the form of freezes and image delays, the inability to get remote access to the video stream and / or peripheral devices for analyzing the received data, which allows you to view the video stream from the video camera in live broadcast mode, low resolution of the video stream received from the camera, small viewing angle and/or heavy contamination of the camera with mud, ice and snow, as well as the inability to install various sensors to obtain additional data.

The problem to be solved by the claimed invention is:

1) Formation of a high-quality, high-contrast, bright static and/or dynamic image and/or video stream on the surface of a vehicle, mobile kiosk, store or other object on which a mobile information system is installed.

2) Ensuring optimal brightness of the backlight of the information screen and the auxiliary display, depending on the level of ambient light, to optimize power consumption and prevent dazzling of external observers.

3) Ensuring uninterrupted, economical power consumption of the mobile information system.

4) Ensuring the operating temperature of the operation of the liquid crystal matrix (hereinafter referred to as the LCD matrix), OLED matrix, and light-emitting diode (LED) matrices.

5) Ensuring a safe temperature of the surfaces of the modules of the mobile information system through the use of a cooling system.

6) In the option of installing a mobile information system on a vehicle, it is required to provide a high-quality view around the vehicle if the glass is covered by equipment, as a result of which a proper view is not provided.

7) Ensuring the transmission of video stream and/or static image to the secondary display without freezes and delays.

8) Preventing the camera lens from being covered with ice, snow and mud.

9) Providing a mobile information system with the ability to receive and transmit data, for example, about weather conditions, location, air chemistry, magnetic field characteristics, and data about what happens to the device during operation / idle time.

10) Ensuring the possibility of placing an information screen on any visible surface using various design solutions, in relation to a vehicle, mobile kiosk, store or other object in which a mobile information system is installed.

11) Ensuring the safety and reliability of fastening the structural elements of the mobile information system to the vehicle, kiosk, store or other facility in which the mobile information system is installed.

The task of forming a high-quality, contrast, bright static and / or dynamic image and / or video stream on the surface of a vehicle, mobile kiosk, store or other object in which a mobile information system is installed is solved due to the fact that the air gap is eliminated in the design of the information screen between the LCD matrix or OLED matrix and a translucent material, where the air gap can be filled with glue or other optically transparent material, which gives a high-quality image due to the absence of light reflection. Uniform distribution of the light flux is achieved by creating a gap between the backlight of LEDs or other light-emitting components and the light-diffusing element. The gap can be filled with an optically transparent material. The introduction of polarizing films or translucent materials with controlled variable light transmission [6] into the design of the information screen reduces the heating of the components of the mobile information system and makes it possible to use reflected light from the outside to illuminate the LCD matrix.

The task of ensuring the optimal brightness of the backlight of the information screen and the auxiliary display, depending on the level of ambient light to optimize energy consumption and prevent blinding of external observers or drivers, is solved by analyzing data received from light sensors and / or processing a video signal coming from one or more video cameras and controlling brightness illumination of the information screen and the auxiliary display.

The task of uninterrupted power supply of the mobile information system is solved through the use of a power supply system. The task of ensuring economical power consumption of a mobile information system is solved by controlling the power supply of the backlight of an external display.

The task of ensuring the operating temperature of the operation of the LCD matrix, OLED matrix, or light-emitting diode (LED) matrix of the information screen is solved through the use of a heating system using a thermoelectric heater integrated into the design.

The task of maintaining a safe temperature of the surfaces of the components of a mobile information system, such as lighting, is solved by using a cooling system that operates on the principle of forced convection, thermal conductivity, phase transition, and their combinations.

The problem of providing a view around the vehicle in the event that the glass is covered by equipment is solved by using one or more video cameras with a wide angle lens, installed in such a way as to provide the best view.

The task of providing the possibility of broadcasting a video stream to an auxiliary display without freezes and delays is solved by using a digital video camera using the MIPI CSI-2 data transfer interface [7] or a digital video camera with another high-speed data transfer interface.

The task of preventing the coating of the body and lens of the video camera with ice, snow is solved by heating the elements of the video camera or its body. The use of structural elements prevents dirt and water from entering the camera lens.

The task of providing a mobile information system with the ability to control the broadcast of images or a video stream remotely is solved by using a wireless data interface.

The task of providing a mobile information system with the ability to receive and transmit data on weather conditions, location, chemical composition of air, characteristics of the magnetic field, data on what happens to the device during operation and idle time is solved by using various sensors in the system, for example: pressure sensor, temperature sensor, humidity sensor, light sensor, global positioning system sensors (GPS, GLONASS or others), MEMS sensors [8], sensors for gas analysis and other, one or more video cameras, one or more microphones for further analysis remotely. Remote access to the mobile information system and data received from sensors is carried out using wireless data transfer interfaces.

The task of providing the possibility of placing an information screen on any visible surface of a vehicle, mobile kiosk, store or other object is solved by unifying the device by using a design consisting of a universal module in which the information screen is located and a replaceable individual bracket corresponding to the installation location on the a specific vehicle, mobile kiosk, shop or other object.

The task of ensuring the safety and reliability of fastening structural elements of a mobile information system to a vehicle is solved by using housings of various designs. The housing can be made in several designs, for example:

1) A wedge-shaped housing that is built between or instead of the rear shelf and/or bodywork of the vehicle and the information screen, an auxiliary display can be built into the housing to display the video stream from the video camera to the driver, and the internal space of the housing can be used to accommodate inside various electronic components.

2) Housing in the form of a "lodge", which has a constructive possibility of placing an information screen in it and can have a built-in auxiliary display, this housing is installed between the glass and the seat for the glass of the vehicle. The case may have places for installing electronic components.

3) A housing that completely replaces the glass of the vehicle, installed on the seat for the glass of the vehicle. The case has a constructive possibility of placing an information screen in it and may have a built-in auxiliary display. The case may have places for installing electronic components.

The task of providing people - third-party observers with access to the Internet is solved using the equipment installed in the mobile information system with a wireless data interface.

The technical results of the claimed invention are:

1) Providing a high-quality, high-contrast, bright static and / or dynamic image and / or video stream on the surface of a vehicle, mobile kiosk, store or other object on which a mobile information system is installed through the use of ....

The implementation of the mobile information system is shown in Fig. 1-3. There is a mobile information system that includes several modules, namely, an information screen (B), one or more video cameras (A), an auxiliary display (E), sensors (H), a computer unit (D), a power supply system (G ), wireless data interfaces (M). All listed modules can be controlled remotely or work autonomously. A mobile information system allows you to remotely receive all information about the object in which it is installed, including receiving a real-time video stream broadcast from one or more video cameras. The resulting video stream and/or a static image can be processed both using a computer unit (D) and remotely, using artificial intelligence and/or a subject having remote access to the system, for example, in order to recognize the faces of observers, individual registration plates of vehicles, road signs, road markings, trademarks, matrix barcodes and other data. Data from sensors installed on an object with a mobile information system can be transmitted remotely via wireless data transfer interfaces or stored in the internal storage memory. The video stream from one or more cameras can be broadcast to other displays installed in the system, such as the auxiliary display (E). In the case of installing the system on a vehicle, as shown in FIG. 1, the auxiliary display (E) displays through the rear-view mirror (I) an image from the rear of the vehicle that has been obscured by the device and is inaccessible to the driver. Video stream from one or more cameras can be directly transmitted to the rearview mirror with built-in LCD or OLED screen. The power supply system (G) ensures the uninterrupted operation of all components of the mobile information system; it can be autonomous or connected to the on-board network. Wireless data transfer interfaces (M) (Bluetooth, Wi-Fi, GPRS, 3G, 4G, 5G and others) allow you to transfer all the information received by the mobile informing system, receive commands through remote control, as well as work in the mode of a wireless access point and have the function of analyzing and / or intercepting network traffic of third-party observers. Remote access, in addition to receiving data from the mobile information system, allows you to control the information displayed on the information screen (B) and other displays. The displayed information on the information screen (B) is controlled by a subject with access to a mobile information system remotely or by artificial intelligence, which, based on sensor readings and video stream from video cameras, selects the information suitable for display. In addition to the above, the mobile information system can perform security functions, for example, artificial intelligence or a subject with access to the mobile information system, based on information received from one or more video cameras and sensors, makes a decision to fix an ongoing illegal act or an emergency (traffic traffic accident, vehicle theft, fire, flood, etc.) and takes appropriate action, such as forwarding the information to the appropriate authorities. If a mobile information system is installed in a vehicle, the system may include an OBD device (P) connected to the vehicle's OBD II connector, which allows receiving and transmitting data from the on-board computer and other vehicle systems.

One or more video cameras can be built-in, for example, in the vehicle antenna module (A), they allow the system to function as a photo and video recorder, broadcast the video stream to displays, this broadcast can be recorded on the local storage of the mobile information system, or can be transmitted remotely . To transfer a video stream without delays in real time with high image quality (at least 1920 × 1080 pixels), video cameras with a MIPI CSI-2 (5.2) interface are used together with a special board (5.3), which allows you to transfer information from a video camera over a distance of more than 300 millimeters without loss of signal quality. The video camera (5.2) may contain a heating element (5.4) to prevent ice and snow from freezing. The housing in which the video camera (5.2) is placed can also be equipped with a heating element and structural elements (5.5) that prevent the objective lens from getting dirty.

The information screen (B) serves to display information that can be of interest to outside observers. The mobile information system can receive information remotely or from its own local storage. The information screen (B) can be mounted on the glass of a vehicle, mobile kiosk, store, or completely replace the structural elements of the facility in which the mobile information system is installed. The LCD matrix of the information screen forms an image for observers in the transmitted light flux from the backlight of the information screen.

In the case of using an OLED matrix, the backlight of the information screen is not used.

The design or various designs are shown in Fig. 5-13. The adhesive composition and/or other transparent material (2) fills the space between the LCD matrix (1.1) or OLED matrix (1.7) and the glass surface (L), which improves the image quality by eliminating light reflections. The transparent layer (2) has a light refractive index close to that of the glass material (L). A layer of transparent adhesive and/or other transparent material (2) contributes to the absorption of vibrations transmitted from the vehicle body to the LCD matrix or OLED matrix, and also eliminates gaps in the structure, eliminating possible noise.

The first embodiment of the information screen is shown in Fig. 5 - 11, where its section is shown. An LCD matrix (1.1) is placed on a light-scattering element (1.2), behind which an optically transparent and/or defocusing layer (1.3a-1.3d) is installed, then a light source (1.4a) is built into the structure, in the form of a 2n-matrix from a large the number of point light sources, for example, LEDs, attached to the surface of a flexible base (1.5), which is a heat-conducting elastic sheet made, for example, of metal with a reflective surface on the side of the light sources (1.4a). Its back surface has a high emissivity to effectively radiate the heat generated by the light source(s).

The optically transparent and/or defocusing layer (1.3a-1.3e) can be made in the form of a combination of the structures shown in FIG. 5-11 ways: space with an air gap and/or filled with a transparent material and/or with diffusing lenses installed, made in the form of a single plate or separately and/or with a flat diffusing lens installed or using other methods of defocusing light and/or filling the space.

The second embodiment of the information screen is shown in Fig.12. An LCD matrix (1.1) placed on a light-scattering element (1.2), the ends of which are provided with an extended light source (1.4b) around the perimeter (1.2). An extended light source (1.4b) is attached to the reflective heat-removing surface of the base (1.5).

The third embodiment of the information screen, made on the basis of a flexible OLED matrix (1.7), as shown in Fig. 13, includes a base (1.5), which is a thin elastic sheet that protects the OLED matrix from damage from the back side.

In all implementations described earlier, polarizing films or a translucent material with controlled variable light transmission [6] can be present to reduce the heating of mobile information system components and use reflected light from the outside to illuminate the LCD matrix. In the off state or in standby mode, both polarizing films or translucent materials with controlled variable light transmission (1.4v, 1.4g) are turned off and do not let light through from the outside into the information screen structure, preventing the components of the mobile information system from heating up from sunlight. When the mobile information system is turned on, the external polarizing film or translucent material (1.4v) is turned off, the light from the outside passes through the LCD matrix (1.1), on which the image is formed, and is reflected back from the switched on internal polarizing film or translucent material with controlled variable light transmission (1.4g) , the image obtained through the transparent layer (2) and glass (L) is transmitted for perception to observers. In this case, the backlight (1.4a, 1.4b) has an auxiliary function, additionally highlighting the image. At night, when the device is turned on, both polarizing films and/or translucent materials with controlled variable light transmission (1.4c, 1.4d) are turned off, allowing the backlight (1.4a, 1.4b) to illuminate the formed image on the LCD matrix (1.1) without hindrance.

The information screen can be installed in an object with a mobile information system installed in it using several design solutions, described below, for example:

The first embodiment of the information screen installation is shown in FIG. 20-22, which shows a section of the structure. The information screen (B) is placed in a housing (6.1), which is fixed to the surface of the vehicle (6.2) by means of a hermetic connection (6.3). From the outside, the information screen is covered with a special coating and/or glass and/or other translucent material that protects the device from environmental influences, infrared and/or ultraviolet radiation, mechanical damage and/or has an anti-reflective and/or anti-reflection coating (6.4). The housing (6.1) can be provided with a detachable connection (6.5).

The second embodiment of the installation of the information screen is shown in Fig.23. The information screen (B) is placed in the universal module of the information screen housing (6.1a). By means of a detachable connection (6.5), the universal housing module is connected to a replaceable individual bracket (6.1b), corresponding to the installation site. The bracket is fixed to the surface of the vehicle (6.2) by means of an airtight connection (6.3). From the outside, the information screen is covered with a special coating and/or glass and/or other translucent material that protects the device from environmental influences, infrared and/or ultraviolet radiation, mechanical damage and/or has an anti-reflective and/or anti-reflection coating (6.4).

The information screen (B) is located in the housing (6.1), or in the universal module of the information screen housing (6.1a), fixed on the surface of the vehicle, mobile kiosk, shop or other object (6.2) with a hermetic connection (6.3), or using an individual bracket (6.1b), corresponding to the geometry of the seat. Detachable connection (6.5) is used to install and/or remove components of the information screen (B) or the universal housing module (6.1a) of the information screen during maintenance and repair.

The third embodiment of mounting the information screen and the information screen itself in the case of installing a mobile information system on a vehicle is shown in Fig. 24, where the LCD matrix or OLED matrix is glued into the glass (L) of the vehicle using a translucent compound that levels the air gap. A backlight is placed from the rear surface to the LCD matrix at some distance, which is held by the body (7.2) in the form of a “wedge” fixed to the elements of the vehicle body and / or on the rear shelf of the vehicle (7.1).

The implementation of the installation of an external display, made according to Fig.20, on the example of the vehicle is shown in Fig. 25, this variant differs in that the body in the form of a "wedge" is replaced by a body (7.3) in the form of a "lodge".

The variant shown in figure 26 differs from the versions shown in figs. 24, 25 by the fact that the glass (L) of the car is completely absent and replaced by a body (7.4) in the form of a "lodge" with its own translucent material (6.4). In this "lodgement" elements of the information screen are located, there is an LCD matrix or an OLED matrix glued into a translucent material of a given shape. This version of the installation of the information screen on the vehicle is also made according to Fig. twenty.

All options for installing an information screen on a vehicle, shown in Figs. 24-26 have the ability to place an auxiliary display, both inside the case and on a suspension bracket, which is attached to the case in the form of a "lodge". The secondary display shows the video stream from one or more cameras.

The mobile information system has the ability to install and connect various sensors (H), such as: pressure sensor, temperature sensor, humidity sensor, light sensor, global positioning system sensors (GPS, GLONASS or others), MEMS sensors, sensors for gas analysis and others. , these sensors can be located both inside the object on which the mobile information system is installed, and outside. All data received from the sensors is recorded in the internal data stores of the mobile information system or transmitted via wireless data interfaces (M) remotely.

The brightness of the information screen and auxiliary display is adjusted by the computer controller on the basis of signals received from light sensors, which can be placed both inside and outside the mobile information system. Depending on the external illumination, for example, at night, the brightness of the backlight decreases, as a result of which the power consumption of the system, its heating is reduced and the possibility of blinding external observers and, if the system is installed on a vehicle, blinding drivers is eliminated.

Brightness control is carried out directly by electric driver boards that control the brightness of a pre-selected channel in a 2n-matrix of light emitting components. Electrical boards - drivers can function in one of the following ways:

1) Backlight brightness adjustment by pulse-width modulation. The backlight module can be divided, for example, into four independent units with LEDs or other light emitting elements. Each block has, for example, four independent channels, this variant of pulse width modulation is implemented with a phase shift on each channel, due to this, only one channel consumes energy at a time. This dimming scheme can be scaled.

2) Backlight brightness control by pulse-width modulation with the possibility of voltage amplitude adjustment. Changing the brightness level is achieved both by changing the duty cycle of pulse-width modulation, and by changing the amplitude of the supply voltage of LEDs or other light-emitting components, as well as their combinations.

3) Current control of backlight brightness. LEDs or other light-emitting components of the 2n-matrix of the backlight module are divided into groups, in which the brightness of the glow is adjusted by changing the magnitude of the current. The advantage of this method is the absence of passive current-limiting components in the circuit.

Temperature sensors installed inside the system structure allow monitoring the surface temperature of the modules of the mobile information system. For example, the temperature sensor (4.7) in Fig.14-17 controls the temperature of the information screen backlight surface (B), if the temperature exceeds a certain value, the cooling system is activated, the backlight brightness is reduced, or both options are applied simultaneously until the surface temperature backlight will not drop to operating temperature. Variants of the implementation of the cooling system are shown in Fig. 14-17, which may include one or more fans (4.1), or a liquid cooling circuit (4.2), or heat pipes (4.5) with heatsinks, and combinations thereof. If the facility where the mobile information system is installed has an air conditioning system (4.6), cooling can be implemented on its basis. The cooling system is controlled by means of information from the temperature sensor (4.7). If the surface temperature drops below a certain value, then the heating system is activated, implemented by heating the surfaces of the backlight of the information screen (B) and / or thermoelectric heaters installed in the glass (L), or in another place, allowing the device to be heated to the operating temperature.

The power supply system (G) provides uninterrupted power to all components of the mobile information system in all possible operating modes, provides control of the charge and discharge of the batteries of the mobile information system. If a mobile information system is installed in a vehicle, the power supply system can be used to start an internal combustion engine and/or can provide power to additional consumers connected to the vehicle with different current loads.

The power supply system consists of the following blocks: one or more batteries of the mobile information system, a switching module, a control module, a switching power supply for providing charging voltage to one or more batteries, a switching power supply for supplying power to the information screen backlight module (B) or other power consumer, power selector to provide power to the mobile information system.

The power supply system works as follows, the control module receives data from the voltage and current sensors of the onboard power supply system, if any, and the battery charge levels of the mobile information system. Based on the data received, the power supply system decides on the choice of the power source of the mobile information system, for example, when one of the batteries is charged to the set level, the power supply system provides power to all elements of the mobile information system. At the same time, the power supply system can charge a second or more batteries. At a certain level of electricity consumed, the power supply system can supply all consumers directly from the on-board network, if available, without the use of batteries. In the event of an insufficient charge level of the mobile information system batteries and / or the power level of the on-board network, the power supply system can reduce the power consumption of the mobile information system by changing the operating modes of the mobile information system components, or by turning off the mobile information system components, while maintaining partial system functionality. The mobile information system can be fully operational, even in the absence of power in the on-board network due to the power supply from the batteries of the mobile information system.

Alternative power sources can be integrated into the power supply system, for example: solar panels, power recovery during braking, etc.
