を高速に直接測定できる。[Operation] While irradiating the laser beam whose intensity is modulated with a high frequency from the laser distance sensor directly toward the object to be measured,
The reflected light is received and the phase difference is detected. When this laser distance sensor is moved in the direction perpendicular to the rail, when it is moved in the direction perpendicular to the track, all equipment on the track within the measurement range of the sensor is detected, but the trolley wire is installed at the lowest position on the track. The height of the trolley wire can be measured by obtaining the lowest value from the height measurement values.
Further, by detecting the position of the laser distance sensor at the time of detecting the object to be measured, the deviation of the trolley wire can be measured from the position occupied by the minimum height measurement value. In addition, by detecting the minimum value of 2 at the overlap point of the simple overhead line, 2 at the general point of the twin simple overhead line, and 4 at the overlap point by the same method, the trolley wire at each point is detected. The height and excursion of the can be measured. When measuring distances and displacements without contact, distance meters using eddy current, ultrasonic waves, and semiconductor lasers are used, but the maximum measurement length of these distance meters is 2
It was about m and it was difficult to measure an object of about 1 cm 2 . The laser distance sensor used in the present invention measures the distance to the measurement object by detecting the phase difference between the laser irradiation light and the reflected light from the measurement object. The measurement range is 3 to 10 m and the resolution is Is 1 mm, the size of the object may be about 1 cm 2 , and the distance to the object to be measured can be directly measured at high speed.

び偏位の測定が行われる。When the limit switch 6 on the left side is contacted by the movement of the laser distance sensor 1, the laser distance sensor 1 starts height measurement, the signal processor 2 inputs the detected signal, and the height measurement is performed by the detection circuit. Convert to a value and write to storage. When the laser distance sensor 1 moves to the right on the track rail 5 while measuring the height to the object to be measured at a constant speed and at constant intervals, and comes into contact with the right limit switch 6 installed at the right end, The laser distance sensor 1 stops moving and ends the height measurement. At the same time, the arithmetic circuit of the signal processor 2 detects the minimum value of the measured values corresponding to the trolley height from all the measured height values written in the storage device, and the minimum value occupies all the measured values. And the trolley wire deviation is calculated from the moving distance of the sensor. The height and deviation of the trolley wire thus detected are displayed numerically or printed out by the display circuit of the signal processor 2. When these processes are completed, the motor driver 3 automatically operates, the laser distance sensor 1 moves leftward on the track rail 5, and moves when it contacts the left limit switch 6 installed at the left end. Stop and prepare for the next measurement. When the measurement is performed again, the start switch 8 is pressed, and the height and the deviation of the trolley wire are measured by the same operation as described above.
