Abstract

FIELD: traffic control system.

SUBSTANCE: invention relates to traffic control systems, namely to global traffic control systems. The control station receives navigation information from the outside and transmits it to vehicles (TS), and also calculates the coordinates of detected objects and transmits them to the search station, where they determine the coordinates, speeds and sizes of detected objects and transmit them to the control station, where they calculate the coordinates of the vehicle and transmit them to the search station, where they determine the coordinates and the vehicle speeds and transmit them to the control station. On the vehicle, their coordinates and desired routes are determined and transmitted to the control station, where coordinate determination errors are calculated on the vehicle and transmitted to the vehicle for correction. The control station determines the recommended routes of the vehicle and transmits them to the vehicle, and also determines the vehicle and detected objects in front of each vehicle and transmits their coordinates, speeds and dimensions to the vehicle to calculate the trajectories of their movement along the recommended routes.

EFFECT: increased vehicle traffic safety.

Description

The invention relates to traffic control systems, namely to global traffic control systems, and can be used to ensure the safe movement of vehicles (TC) at all stages of their traffic control.

A known method of controlling the movement of vehicles (US 8538673), in which the control station receive navigation information from the outside; on the vehicle determine their current coordinates, and transmit them to the control station; at the control station, the recommended routes of the vehicle are determined, and they are transmitted to the corresponding vehicles.

Closest to the proposed is a method of controlling the movement of vehicles (RU 2746058 C1), in which the control station receives navigation information from the outside; on the vehicle determine their current coordinates and desired routes, and transmit them to the control station; at the control station, the recommended routes of the vehicle are determined.

However, in the known methods, the safe trajectories of the vehicle along the recommended routes are calculated at the control station, which reduces the accuracy of the calculations due to the remoteness of the control station from the vehicle. At the same time, the global satellite navigation system does not work in the areas of application of electronic warfare, which reduces the accuracy of determining the coordinates of the vehicle using onboard inertial navigation systems, and in known methods these coordinates are not corrected. In addition, the known methods do not search for foreign objects that the vehicle may encounter.

These shortcomings of the known methods lead to a decrease in vehicle traffic safety.

The purpose of the invention is to improve the safety of the vehicle.

The proposed method is that:

- at the control station they receive navigation information from the outside, and transmit it to the vehicle;

- at the control station, the exact current coordinates of the detected objects are calculated and transmitted to the corresponding search stations;

- at the search stations, previously discovered and new objects are detected, the coordinates, speeds and sizes of the detected objects are determined, and they are transmitted to the control station;

- at the control station, the exact current coordinates of the vehicle are calculated, and they are transmitted to the corresponding search stations;

- at the search stations, the coordinates and speeds of the vehicle are determined, and they are transmitted to the control station;

- on the vehicle, their current coordinates and desired routes are determined, and they are transmitted to the control station;

- at the control station, the current errors in determining the coordinates on the vehicle are calculated, and they are transmitted to the corresponding vehicles for correction;

- at the control station, the recommended routes of the vehicle are determined, and they are transmitted to the corresponding vehicles;

- at the control station, the vehicle and the detected objects that are in front of each vehicle are determined and their coordinates, speeds and sizes are transmitted to the corresponding vehicles in order to calculate the safe trajectories of the vehicle along the recommended routes.

Vehicles can be surface, air or space, and search stations - radar, television, laser or combined (US 10453351). With the vehicle, their characteristics are transmitted to the control station.

At the control station, navigation information is received from outside and transmitted to the vehicle, which contains digital maps of the area, as well as the coordinates and sizes of dangerous and restricted areas.

At the control station, the coordinates of the vehicle and the detected objects are calculated based on their coordinates and velocities received from the search stations in the previous cycle, and the time points of their determination at the search stations. From the control station, the coordinates of the vehicle and the detected objects are transmitted to the search stations, in whose review sectors they are located.

At the control station, previously discovered and new objects are distinguished by comparing their coordinates received from the search stations with the coordinates of the objects transmitted to the search stations.

On the vehicle, their coordinates are determined using onboard inertial navigation systems, corrected using a global satellite navigation system, and the desired routes are determined using pilots or autopilots.

At the control station, the recommended routes of vehicles are determined based on the need to prevent their dangerous proximity to objects and other vehicles, as well as the need to bypass dangerous and restricted areas.

The proposed method can be implemented in the system, the block diagram of which is shown in the drawing.

Blocks: 1 - control station; 2 - search stations; 3 - TS.

Connections between blocks: 1-2 - exact current coordinates of the vehicle and detected objects; 1-3 - navigation information, current errors in determining the coordinates on the vehicle, recommended routes of the vehicle, as well as the coordinates, speeds and dimensions of the vehicle and detected objects that are in front of each vehicle; 2-1 - coordinates, speeds and sizes of detected objects, as well as coordinates and speeds of the vehicle; 3-1 - current coordinates and desired routes of the vehicle; 4-1 - navigation information.
