摘要:PURPOSE:To attain sure detection by deciding the classification of abnormality and abnormal location from the detection of a reflection wave by means of a receiving ction of a station when a reception signal with respect to a transmission pul includes the reflection wave. CONSTITUTION:A pul of positive reflecting wave is given to a deciding circuit 11 from an AND gate 10 and a pul of negative reflecting wave is given from a comparator 8. The discrimination circuit 11 counts times TP, TN till a reflecting wave pul is given bad on an output pul timing of a reception signal or a transmission signal such as an output of an inverter 9. The disconnection or short-circuit at a point X is decided by the deciding circuit 11 depending on the difference of the detection of the given reflection wave pul to be positive or negative, and the distance from a station 21 till the point X is decided depending on the times TP, TN till the reflecting wave is given.泥鳅汤的做法
