Catenary Diagnostic System Without Contact (MESICA)

DESCRIPTION – CATENARY DIAGNOSTIC SYSTEM WITHOUT CONTACT

Its mission is to diagnostic overhead contact lines (catenary) by recording the height and the offset measures. The height and the stagger of the catenary are measured without contact by artificial vision.

  • Warning alarms in real time.
  • Poles are detected automatically by laser technology and software.
  • Compensation of the suspension by potentiometer or LVDT.
  • Record the GPS position and the odometry of the train.
  • Recording and watching a video on inspection. Take inspection samples every 0.25 m and stored in database.
  • Calculation of the slope between poles, Pantograph arm, Sag and against-sag.
  • Allows viewing, printing and exporting the inspection data to Excel.

MAIN FEATURES

INSPECTION OF CATENARY TAKING MEASURES OF HEIGHT AND STAGGER

  • Speed of inspection: 60 km / h – 160 Km/h.
  • Measuring range of the laser height: 4.4 m – 6.2 m.
  • Stagger measuring range: from -47.5 cm to +47.5 cm.
  • Resolution of height and stagger: 1.4 mm with an accuracy of 0.06%.

HEIGHT AND STAGGER MEASURES ARE USED TO COMPENSATE THE SUSPENSION BY MEANS OF LVDT SENSORS

  • Measuring range of suspension: ± 50 mm.
  • The measurement error of the crushing allowed is ≤ ε % = 10.0 (5 mm).
  • The measurement error of the tilting allowed is ≤ ε % = 2.5 (5 mm).

READING TRAIN POSITION BY GPS

  • RS232 Interface Protocol (NMEA0183).
  • Sensitivity: -150 dBm.
  • Data output ratio: 0.5 to 4 Hz
  • Accuracy with DGPS: 2.6 m.
  • 3 channels SBAS (EGNOS, RTCM-BASS).

AUTOMATIC DETECTION OF POLES BY LASER TECHNOLOGY

  • Operating Frequency: 250 Hz
