Description
Technical field
The present invention relates to a kind of sensor device and installation method thereof, especially relate to a kind of Multi-channel non-contact Hall revolution speed transducer and installation method thereof that the rail traffic vehicles such as locomotive, motor-car, high ferro train test the speed that be applied to.
Background technology
Along with the Now Domestic train speed and load-bearing capacity growing, safe driving is also paid close attention to more and more widely and is paid attention to.This just requires train must accurately and reliably receive current running speed signal.At present, the sensor that is applied to locomotive is mainly to adopt photoelectric sensor, Hall revolution speed transducer and magnetic power rotation speed sensor.
Existing photoelectric sensor is arranged on locomotive shaft-end, for locomotive provides travelling speed and traffic direction, the sensor input shaft is connected with the tested wheel shaft of locomotive, tested wheel shaft drives the rotation of sensor input shaft, its rotating ratio is 1:1, utilize photoelectric principle, produce frequency and the electric impulse signal that the wheel shaft rotating speed is directly proportional, offer the motorcycle safety train control system and realize testing the speed.But locomotive is in the process of operation, the vibration of wheel set bearing is larger, dirt is more, photoelectric sensor is worked for a long time in the environment of vibration, impact, dirt, make sensor signal be subject to serious impact, have the passage no signal, lose pulse, the phenomenon such as phase differential is overproof, greatly reduce its reliability.
Existing Hall revolution speed transducer is arranged on the locomotive gear end cap, its transmission mode is non-contact type, this sensor is comprised of mounting flange, Hall element, magnet, shell and output cable, although overcome the deficiency of photoelectric sensor contact transmission mode, but the Hall revolution speed transducer port number of prior art is two passages, can not well meet the requirement of railway signal Redundancy Design.In order to meet the requirement of train control system Redundancy Design, need to install a plurality of two passage Hall revolution speed transducers, bring great inconvenience to locomotive wiring, maintenance and maintenance like this.
Existing magnetic power rotation speed sensor is arranged on the locomotive gear end cap, its transmission mode is non-contact type, magnetic power rotation speed sensor is comprised of inductive coil, magnet, mounting flange, shell and output cable, sensor is along with gear rotates the sine wave signal that output frequency is directly proportional to rotating speed, but at rotating speed under lower condition, the output of magnetic power rotation speed sensor no signal, cause the locomotive train control system can't read the magnetic power rotation speed sensor rate signal when locomotive low speed.
