RAILWAY TRACK MONITORING SYSTEM BASED ON OSCILLATION MEASUREMENT.

摘要

ABSTRACT A railway track monitoring and fault locating system for real time oscillation measurement based on GPS/GPRS, the system comprising: a computer run by using any operating system and supplied with power from a rechargeable power supply unit; a GPS/GPRS modem locating the system position in real time and for sending SMS to concerned personnel and/or devices; a transducer-cum-signal conditioning unit for recording and conditioning oscillations and to calculate and transmit the acceleration values; and a control unit between the transducer-cum-signal conditioning unit and the computer, which is pre-stored with relevant pole-database; wherein the transducer-cum-signal conditioning unit is mounted on the axle or axle pivot point of the railway coach in a true horizontal and vertical position. The invention also provides a method for monitoring the railway track and locating fault by this system by real time oscillation measurement based on GPS/GPRS. FIGURE 1.
