Van edge rolling bearing early faults rail acoustic diagnosis system introduction

Trucks rolling bearing in the early 2020 - the rail edge acoustic fault diagnosis system profile 01 - 02 TADS is Trackside & Detection System, namely trucks rolling bearing early faults in Chinese rail side acoustics diagnosis System, van edge rolling bearing early faults rail Acoustic diagnosis System TADS for short. Van edge rolling bearing early faults rail acoustic diagnosis system, in the 1980 s, by the American academy of TTCI research by using the acoustic diagnosis principle, and used to detect the vehicle's rolling bearing faults in the operation system. Introduced in 2003 and is widely used in. TADS mainly USES the acoustic technology and computer technology, the use of rail side array acoustic acquisition, real-time acquisition run trucks rolling bearing noise, through the data analysis, early detection bearing early faults. Key test truck rolling bearing fault, inner and outer ring raceway and roller before hot shaft failure prediction for bearing fault; Complementary and infrared temperature monitoring system, to prevent cutting axis accident, to ensure driving safety. Pieces TADS main functions are as follows: to detect the through train rolling bearing roller, inner sleeve, coat if there is a crack, peel, wear and corrosion failure. Automatic pieces of axle, vehicles, speed. Can detect a maximum of 300 vehicles. Automatic identification of mixer train services, car number information. The development trend of mixer automatic tracking fault bearing. The mixer forecast is divided into 3 levels and 1 - Level 3. To adapt to the speed: 30 - 110 km/hour. Mixer has a complete database functions, automatic recording, statistics and analysis of all kinds of coaxial type rolling bearing operation state of the vehicle, automatically generated monthly annual statistical analysis report, for the vehicle maintenance by timing to state trim to provide reliable data, which provides the basis for related technical policies for the ministry of railways. Mixer system has self-checking, remote maintenance, software upgrades, and monitoring capabilities. Detection accuracy is very high, accuracy can reach 97%. （ Source: the resources of railway vehicle platform)
