METHOD FOR INTERVAL REGULATION OF TRAIN TRAFFIC, USING BLOCK SECTIONS, TRAFFIC LIGHTS, AND DETECTION OF INTERFERENCE IN OPERATION LOGIC Russian patent published in 2022 - IPC B61L3/12 

FIELD: railways.

SUBSTANCE: invention relates to methods for interval regulation of train traffic, using block sections, traffic lights, and detection of interference in the operation logic. In the method: information about a state of all lamps of each wayside traffic light is continuously received, and a signal indication type is determined according to them; signal indication types are cyclically compared between each other in pairs, according to the selected direction of movement along a route of the stage, taking into account insertional characteristics of system equipment for each route of the stage. If the signal indication type of any traffic light is not forbidding and, at the same time: it and the signal indication type of the wayside traffic light next in the direction of movement along the route of the stage coincide, and the signal indication type of the considered traffic light requires the speed limitation, or it and the signal indication type of the wayside traffic light next in the direction of movement along the route of the stage do not coincide, and the signal indication type of the considered traffic light is more permissive, then the interference in the operation logic is registered with the indication of corresponding stage route number, direction of movement along it, traffic light designation. Then, a notification signal to duty and dispatch personnel and each controlled railway rolling stock on this stage route is formed, containing information about the stage route number, the direction of movement along it, and the traffic light designation. After receiving the notification signal, using safety devices placed on the controlled railway rolling stock, when approaching the corresponding traffic light, actual and maximum permissible speeds are lowered to a level providing the possibility of stopping, when the traffic obstruction is detected, until reaching the traffic light following it in the direction of movement.

EFFECT: increase in a level of safety of train traffic is achieved.
