Implementation of a utility model.

The system for notifying drivers about the traffic situation on the basis of the microcontroller is an information management system and consists of a set of devices that are equipped with software. The operation of the software is based on the interaction of the microcontroller with other elements of the system. This system is designed for a private car. The device (8) with dimensions (70 × 30 mm) is attached on the left (left-hand drive) to the windshield of the car. The device is connected to the power supply unit (7) of the car; if the power supply unit is damaged as a result of an accident, the device has an autonomous battery (not specified). The device includes: a receiving part (1), a transmitting part (2), a codec-decoder based on 3

microcontroller (3), buttons (4), 4 LEDs (5) (indicators), sound buzzer (6). After it arrives at the information receiving device

signal from other sources (special vehicles, another car, etc.), the device transfers data to the microcontroller, where the data is processed and the microcontroller controls the LED block (i.e., the driver sees a certain light), as well as a buzzer, which in turn emits a sound signal. Red LED - prohibits, warns of danger on the road, travel during the repair of roads, bridges and emergency situations (accident); Blue LED - warning the driver about the movement of specials. transport; Yellow LED - warning about the creation of an obstacle on the road; White LED - permission to move at level crossings (fog at which a traffic light is not visible);

If the driver gets into an emergency, then when the button is pressed (warnings, danger), the signal (9) goes to the microcontroller, where the data is processed and the microcontroller sends a command to the information transfer device, which in turn alerts the drivers with a red LED about the danger on the road ( fig. 2). The signal is transmitted at a frequency of 433.92 MHz, the radius of the signal in the city is 200 meters, respectively, along the highway. When two signals arrive simultaneously at the receiver (probability of overlap 1:20), the random number generator is in the controller.

You can also manually turn off the device when a signal appears, and when a signal from a new source appears, the system turns on automatically.

This technical solution allows you to increase the amount of incoming information and is an additional warning to drivers on the radio channel about an obstacle on the road.
