Abstract
PURPOSE:To facilitate adjustment while enabling a plurality of track circuits to be dealt with a set of receivers operated by the track side voltage, the local side voltage and phase difference between both voltages, by constituting the phases of the local and track side voltages to be automatically corrected. CONSTITUTION:When the local side voltage is changed from negative to positive one, a change detecter 2 generates the output pulse and a wave form generator 4 generates the local side voltage wave form after a time delayed by a time lag setter 3. This local side voltage is multiplied by the track side voltage in a multiplier 5 and then the average is obtained in an average movement processing section 6. The average value is compared with a train detecting level by a comparator 7 to generate the train detecting output. Also, a time in which the track side voltage is maximized is detected by a maximum value detector 8 and a time measuring instrument 9 measures a period of time from the pulse output of change detector 2 to the detection of maximum value of track voltage. The result of measurement is sent to the input of time lag setter 3 through AND gate 10 to automatically set the time lag.
