PURPOSE: To display each measured data on chart paper in time series by arranging each pole detecting pulse(PD) of each measurement, pole numbers and each distance pulse (PK) in travelling measurement at a plurality of times of an electric detecting-measuring car at the same place. CONSTITUTION: An interval correction circuit 56 is mounted on the measuring section 5 of a detecting-measuring car, and the reduction of the intervals of each distance pulse (PK) owing to the abrasion of the wheels of the detecting- measuring car is corrected. An MPU and a hard disk(HD) are added to a ground device, each pole number stored in a plurality of flexible disks(FD) 554 by each travelling measurement is decoded by the MPU every time each travelling measurement is completed, each pole detecting pulse(PD) is arranged at the same place, and each measured data and each distance pulse (PK), in which intervals are corrected, are stored in the HD. The measured data of travelling measurement in required numbers are selected from the HD, and recorded in parallel on chart paper 63 and displayed in time series. |
