DEVICE FOR COLLECTING AND RECORDING DATA ON CONDITION OF AXLE BOXES OF RUNNING TRAIN Russian patent published in 1997 - IPC

FIELD: railway transport. SUBSTANCE: device has first and second self contained travel pickups and first and second axle box temperature control chambers placed in tandem in first and second measuring channels. first and second analog comparators of operating signals and levels preset by reference voltage source are placed in measuring channels in series with axle box temperature control chamber. First and second inputs of reference voltage source are connected with setting inputs of first and second comparators, respectively. It has first storage recorder of results of axle checking threshold values, information inputs of cells of recorder being connected with outputs of corresponding comparators, second recorder-shaper of running vehicle axle signals, third recorder of address and results of checking of running vehicle axles, first checking commencement signal shaper connected in series with first travel pickup, second wheelset passing and end of checking signal shaper, connected in series with second travel pickup, third checking cycle shaper whose output is connected with united strobe inputs of comparators, and car-to-car distance identification pickup. Output of third shaper and first input of car-to-car distance identification pickup are connected with output of first shaper. EFFECT: enhanced reliability of checking. 2 dwg
