Description

Technical field

The technical solution concerns the sharing of image data between cars.

BACKGROUND OF THE INVENTION

Embedded systems are devices consisting of a control unit, one or more microcontrollers controlling sensors and actuators to interact with the environment. The cyberphysical system (CPS) enables sharing, exchange, data (including image) between CPS elements. CPS connected to the Internet is also known as the Internet of Things (IoT). Autonomous cars today operate on the principle of such nested systems, consisting of multiple spatial cameras that capture a 360 degree range within 250 meters of an automobile, ultrasonic sensors that detect hard and soft objects up to 400 meters, and radar providing environmental data regardless of rain, fog, dust. Other systems, to increase traffic safety in non-autonomous vehicles, operate on the principle of laser sensors located behind the rear-view mirror inside the vehicle. The laser sensor detects the road with a laser within a distance of about 10 meters from the car and sends a signal to the vehicle control unit. If the laser detects an obstacle on the road and the driver does not react to it, the vehicle control units initiate the deceleration process. vehicle braking. The disadvantage of these systems is efficiency only up to a speed of about 40 km / h. A device consisting of a system for safe circulation of trucks, which are currently tested and exist as prototypes, but are not yet standard equipment for trucks (Samsung Safety Truck - A camera and a screen that save lives! [Cit. 2017-0802], Available from https://www.novascientia.net/articles/231/Samsung—Safety-Truck—-A-cameraand-a-Screen-that-save-lives) are also based on the principle of embedded camera systems that capture space in front of expensive and a display unit located on the back of the truck trailer. The image from the camera system is projected on the display unit at the rear of the semi-trailer, allowing the driver of the vehicle behind the truck to see the traffic situation in front of the truck well in advance without the need for a partial or complete deviation of the lane. This solution has limitations resulting from the visibility of the projected image. Today's 4G networks with 100 Mbps transfer rates allow you to transmit image data between moving objects in the desired dynamic mode, but are not adapted to transmit image data from IoT devices.

The sharing of image data by two or more cars driving in series at a particular time and space, in order to circulate the car more safely, on the principle of a device for sharing the image data between cars while circulating, is not currently used in the automotive industry.

The essence of the technical solution

The essence of the technical solution lies in the use of embedded in-car systems, their connectivity to transmission systems, CPS, respectively. IoT devices. Telecommunication networks are used to share data between cars, which allow the transfer of image data between moving objects. A device for sharing video data between cars while circulating is formed by a camera, an image data transmitter connected to a telecommunications network, an image data receiver connected to a telecommunications network, and a display unit. The camera, which is located on the front of the circulating car, respectively. in front of the orbited car interior, captures the image in front of the orbited car. The image data from the camera of the orbiting car is transmitted, as mobile data in the telecommunications network, to the orbiting car by the image data transmitter connected to the telecommunications network. A receiver connected to a telecommunications network in a circulating automobile receives image data, in the form of mobile data in a telecommunication network, from the circulating automobile and displays them on the display unit of the circulating automobile. In order to be able to use this system universally, i. the orbited car can also become orbiting, it is necessary that all the elements of the image data sharing device between the cars while circulating with each other be installed in both the orbiting and the orbiting car. The elements of the device for sharing the image data between cars while circulating with each other may be individual devices such as e.g. a mobile phone containing the individual elements of the proposed car-to-car image sharing device as well as IoT devices with car-to-car image sharing device elements operating on the CPS or CPS connectivity principle; IoT devices as part of a car-to-car image sharing device. Depending on the equipment level, today's cars may have a built-in WiFi unit that allows connectivity to the car's information system.

Advantages of the technical solution:

• the possibility to see the area in front of the orbital car when overtaking without partial or complete deviation of the lane, • increase of safety and information of road users, • sharing of image data, when equipping the device for sharing image data between cars while circulating, • sharing of other image data needed for traffic flow control, • car-to-car image sharing device that interacts more comprehensively and securely with the embedded system, • interfaces with all existing traffic safety systems installed in cars, such as emergency braking systems, seat belt fastening, etc., • intelligent road traffic control.

Disadvantages of the technical solution:

• The need for coverage of the telecommunications network signal with the required transmission parameters. • Not applicable in areas with strong electromagnetic fields.
