Description

Electronic odometer for rail vehicles

The invention relates to an electronic path «», counter for rail vehicles with autonomous or centralized power supply system, especially for passenger coaches »

There are already electronic Wegstreckenzähler.für the detection of the mileage of vehicles known »Such a solution is described (DD-TCP 133 584 - Cl. G 01 C, 22-00). The pulse generator used is a rotary generator present on the vehicle and intended for the power supply of the vehicle. Between the three-phase generator and a scheduled pulse divider an occurring distortions of the alternating current of the alternator correcting pulse shaper is involved. The pulse divider is set according to the mean permissible wheel diameter of the vehicle wheel »:

The disadvantage of this invention is that the odometer only in a particular type of pulse generators, the alternator., Is used ο In the context of the introduction of the central power supply in the train but modern passenger cars are no longer equipped with axle generators.

A further disadvantage is that the current wheel disc wear can not be taken into account with greater deviation from the permissible fault tolerance and the possible replacement of the bogie and the sudden change in the wheel disc diameter associated therewith. A simple calibration possibility of an odometer is to be achieved (DE-OS 2201251 Kl. G 01 C 22-00) by the use of a potentiometer. However, potentiometers are not suitable for use in rail vehicles, due to the high mechanical stresses that occur and the low long-term behavior.

Object of the invention

The useful effect of using the invention is to provide an electronic odometer for railway vehicles which is more economical to manufacture and simpler to maintain, thereby providing greater operational reliability of the entire equipment under the robust conditions of railroad operation. "

The alternating voltage generated by the pulse generator 1 is supplied to the pulse shaper 3 via a pulse amplifier 2.1. In the pulse shaper 3, the AC voltage is converted into a digitally suitable pulse train. This now available pulse train can be processed by the electronic pulse dividers, the generator adaptation stage 4 and the wheel-docking stage 5.

The first electronic pulse divider, the generator adaptation stage 4, can be programmed by the Yorwahldrehschälterblock 7 so that at the output of the generator «- adjustment stage 4 one pulse per wheel revolution is available» The second electronic pulse divider, the wheel adjustment stage 5, evaluates the Pulses of the generator adaptation stage 4 off »After the required wheel revolutions per kilometer adjustable with the preselection rotary switch ·» block 8, the electronic pulse divider, the wheel adjustment stage 5 »gives a pulse to the impulse amplifier 2« 2 and this controls a counter 6, for example, a 6 "digit electromechanical counter to.
