Description
Technical field
The present invention relates to a kind of multipurpose track sensor, it is arranged on railroad track inner side, belongs to the signal pickup assembly of train operation state.
Background technology
Existing China railways are used to gather the rail sensor of train operation state information, mostly magnetoelectric sensor, mainly constituted by permanent magnet and around coil thereon, when magnetic field of the train wheel by rail sensor permanent magnet circuit, cause magnetic flux change, being wound on will produce pulse voltage of reaction in the coil on permanent magnet.This rail sensor weak point that uses is at present：Mostly single information, be such as intended to meter shaft, test the speed, direction finding, it is necessary to more than three sets of sensor is installed.Inconvenience is installed, high cost, magnetic structure is unreasonable, poor anti jamming capability, and can not effectively recognize the special train operation states such as the direction started again after the Train Stopping in emergency circumstances occurring, interval regression and parking.In today of scientific and technical high speed development, can not meet under railway sternness complex environment, the requirement that modern railways information construction becomes more meticulous, simplifying, reliability and stability are high.
The content of the invention
It is an object of the invention to provide a kind of multipurpose track sensor, can the various running statuses of effectively perceive train, and do not receive electromagnetic interference influence, meter shaft can be reliably used for, test the speed and judge current of traffic.
To realize its goal of the invention, the technical solution adopted in the present invention is, a kind of multipurpose track sensor, and its composition is：It is made up of base steel plate, two general magnets, dividing plate, two kicker magnets, two permanent magnetism coils and shells.
At a distance of 2mm between two described general magnets, N poles are fixed with dividing plate, S poles and base Interal fixation.
Two described kicker magnet S poles are fixed with dividing plate, and N poles are inserted into two permanent magnetism coils.
Described two permanent magnetism coils series connection, between at a distance of 5mm, bottom and surrounding filling epoxy resin, poured by epoxy resin and be fixed on shell.Two permanent magnetism coils are wound in the same direction using the enamel-covered wire of 0.21mm, the number of turn 10000 ~ 20000.
Described shell is made with using polystyrene.
Operation principle of the invention is：
Two kicker magnets being fixed on dividing plate form two effective operating fields with two permanent magnetism coils being connected on shell are fixed on, and when train wheel wheel rim process is stuck in the transducer tip on the inside of steel pipe, by two magnetic circuits of coil of first rear enclosed, shorten magnetic circuit.Due to being changed through the magnetic flux of permanent magnetism coil, induced voltage pulse signal will be produced at coil two ends, due to often passing through an axletree, a pulse signal can be produced, waveform then according to pulse signal, number, time interval, can effectively judge traffic direction, the number of axle and the speed of service of train.
The two general magnets and dividing plate being also secured on base steel plate form two relatively closed short magnetic circuit magnetic fields, are effective against from outside electromagnetic interference, it is to avoid operating fields are influenceed by external electromagnetic interference, make the more stable reliability of signal output.
Compared with existing sensor, it is an advantage of the invention that：
1st, structure design is simple, reasonable, is not influenceed by external electromagnetic interference, strong antijamming capability, can stabilization, reliably outside output pulse signal.
2nd, it is powerful, it is widely used, can be used for meter shaft, test the speed, direction finding, and can effectively recognize the special train operation states such as the direction started again after the Train Stopping in emergency circumstances occurring, interval regression and parking.
3rd, the shell and base steel plate that polystyrene is made form full-closed structure, on the premise of sensor function is ensured, are prevented effectively from the influence of the severe complexity adverse circumstances of railway.
