FIELD: railway transport; signaling and communication. ^ SUBSTANCE: invention relates to interval control of traffic. According to proposed method ac voltage is supplied to middle of rail line and information of running voltages is received at ends of line and, basing on this information occupation or clearing of rail line is revealed. If occupation threshold exceeds ratio of voltage of rail line input end to voltage of output end, rail line is considered occupied. Used as occupation threshold is occupation coefficient. Clearing of rail line is recorded if several conditions are met: equality of voltage at ends of rail line at current of supply end exceeding threshold current and than at excess of ratio of voltages of rail line output end to voltage of input end over clearing threshold are checked. Clearing coefficient is used as clearing threshold, and occupation of rail line following in direction of running is recorded. ^ EFFECT: improved reliability of checking condition of rail lines. ^ 2 dwg |
