Description

Technical field

Technical solution of the use 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 enabling interaction with the environment. The Cyber-Physical System (CPS) allows mutual use, exchange, data (including imaging) between CPS elements. CPS connected to the Internet is also known as the Internet of Things (IoT). Autonomous cars are currently operating on the principle of such nested systems, consisting of multiple spatial cameras that capture 360 degrees within 250 meters of the car by ultrasonic sensors that allow detection of hard and soft objects up to 400 meters and provide radar data to the surroundings regardless for rain, fog and dust. Other systems, to increase traffic safety for non-autonomous vehicles, operate on the principle of laser sensors located behind the rear-view mirror inside the vehicle. The laser scanner detects the road with a laser at 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 the speed of about 40 km / h. Equipped with a secure truck bypass system, which are currently tested and exist as prototypes, but are not yet standard truck equipment (Samsung "Safety Truck" - A camera and a screen that save lives!) 02], available from https://www.novascientia.net/articles/231/Samsung-Safety-Truck—A-camera-and-a-Screen-that-save-lives), are also based on the principle of embedded systems, a camera system sensing the area in front of the lorry and a display unit located on the rear of the lorry trailer. The image from the CCTV 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 partial or complete deviation of the lane. This solution has limitations resulting from the visibility of the projected image. Current 4G networks with 100 Mbps transfer rates allow the transfer of image data between moving objects in the desired dynamic mode, but are not adapted to the transmission of image data from IoT devices.

The mutual use of image data by two or more cars driving in series at a particular time and space, for the purpose of safer car circulation, on the principle of a device for the mutual use of image data between cars in circulation, is currently not 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 with transmission systems, CPS, respectively. IoT devices. Telecommunications networks are used to exchange data between cars, which allow the transfer of image data between moving objects. A device for the mutual use of image data between cars in a mutual circulation 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 the front of the orbited car interior, it captures the image in front of the orbited car The image data from the orbited car camera is transmitted as image data connected to the telecommunications network as mobile data in the telecommunications network to the orbiting car. 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 a circulating automobile and displays them on a display unit of the circulating automobile. To be able to use this system universally, i. j. the orbited car can also become orbiting, it is necessary that all elements of the device for the mutual use of the image data between the cars in the orbiting be installed both in the orbiting and in the orbiting car. Individual devices, such as e.g. a mobile phone containing the individual elements of the proposed car-to-car picture-to-vehicle inter-device, as well as IoT devices with car-to-car picture-to-car inter-vehicle devices, operating on the CPS or CPS connectivity principle; IoT devices within a vehicle-to-vehicle image-to-device system. Existing cars may have

Advantages of the technical solution:

• the possibility of seeing the area in front of the orbital car when overtaking without partial or complete lane departure; • increasing the security of road users' awareness; • the mutual use of image data when equipped with a device for the mutual use of image data between cars when circulating; • the mutual use of image data between cars in a circulation, which, in comparison with the embedded system, reacts more comprehensively and safely, • the possibility of interconnection with all existing systems to increase traffic safety 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.
