Abstract
The utility model relates to a wheel sensor, comprising a pair of receiving and sending magnetic heads which are respectively positioned on two sides of the two rails for the same railroad line. The signal output ends of each pair of receiving and sending magnetic heads are respectively and electrically connected with signal input end of the machine shaft checking device. The alternating magnetic field produced by the sending magnetic heads is respectively passing through the internal loop of the receiving magnetic head positioned on the other side of the same rail to form the induced voltage. Two pairs of receiving and sending magnetic heads synchronously collect the wheel information when the trail passes to form the wheel shaft information as the condition for the machine shaft device statistics wheel shaft. The utility model has the advantages that: the utility model greatly improves the anti-interfering ability for the machine shaft checking device, reduces the installation precession requirement for the position of the sensor, and the adjustable range is increased, and the construction difficulty is reduced.
Description
Technical field
The utility model relates to the electromagnetic type active sensor, especially relates to the wheel detector of railroad track axle counting system.
Background technology
How use the wider wheel detector that axis-counting device adopted at present is made up of transmission magnetic head that is installed in the same one steel rail of rail track both sides and reception magnetic head.Through out-of-date, because the shielding action of wheel, the alternating voltage phase place and the amplitude that make the transmission magnetic head magnetic line of force pass through the induction of receipts magnetic head Inside coil all change thereupon as wheel; When wheel was crossed magnetic head just, it is maximum that phase change reaches, and axle counting system is handled this induced voltage, forms the axle pulse signal, as the condition of axis-counting device statistics wheel shaft.The deficiency of its existence is anti-external interference ability, for example when external interference such as the monorail trolley of railway department and bucket, spades, all can cause the mistake identification and the maloperation of axle counting system; The installation site of sensor requires relatively strictness when mounted simultaneously, has increased difficulty of construction.
The utility model content
The wheel detector that provides a kind of antijamming capability strong, reliable and stable is provided the utility model purpose.
For achieving the above object, the utility model can be taked following technical proposals:
Wheel detector described in the utility model, it is made of a pair of reception that is separately positioned on same rail track two one steel rail both sides, transmission magnetic head; Described every butt joint sending and receiving send the signal output part of magnetic head to be electrically connected with the signal input part of meter axis detector respectively; The alternating magnetic field that sends the magnetic head generation passes through respectively and is installed in the Inside coil formation induced voltage that same one steel rail opposite side receives magnetic head; Two butt joint sending and receiving are sent magnetic head to gather train jointly and are formed axle information through out-of-date wheel information, as the condition of axis-counting device statistics wheel shaft.
Described every butt joint sending and receiving send magnetic head all to be structure as a whole.
The utility model advantage is to be respectively arranged with by receiving, sending the sensor that magnetic head constitutes in the both sides of two one steel rails of same circuit, gathers train jointly and forms axle information through out-of-date wheel information, as the condition of axis-counting device statistics wheel shaft.Like this, external interference such as the monorail trolley of railway department and bucket, spade can not be disturbed the sensor that is installed on same circuit two one steel rails simultaneously, what at this moment count the axis detector reception is the pulse signal that a certain one steel rail two side sensers produce, be that this pulse signal of decidable is that external interference causes, do not participate in wheel number of axle statistics, improved meter repacking measurement equipment antijamming capability greatly, relaxed the position installation accuracy requirement of sensor, adjustable range is enlarged, and has reduced difficulty of construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, wheel detector described in the utility model, it is made of a pair of reception that is separately positioned on same railway line two one steel rails 1,2 both sides, 3,4 of magnetic heads of transmission; Described every butt joint sending and receiving send the signal output part of magnetic head 3,4 to be electrically connected with the signal input part of meter axis detector respectively; The alternating magnetic field that sends the magnetic head generation passes through respectively and is installed in the Inside coil formation induced voltage that same one steel rail opposite side receives magnetic head; Two butt joint sending and receiving send magnetic head 3, the 4 common trains of gathering to form axle information through out-of-date wheel information, as the condition of axis-counting device statistics wheel shaft.Every butt joint sending and receiving send magnetic head 3,4 all to be structure as a whole, and can be inserted into easily on the upright beam of rail 1,2 like this.
Claims (2)
1. wheel detector is characterized in that: it by a pair of reception that is separately positioned on same railway line two one steel rails (1,2) both sides, send magnetic head (3,4) and constitute; Described every butt joint sending and receiving send the signal output part of magnetic head (3,4) to be electrically connected with the signal input part of meter axis detector respectively; The alternating magnetic field that sends the magnetic head generation passes through respectively and is installed in the Inside coil formation induced voltage that same one steel rail opposite side receives magnetic head; Two butt joint sending and receiving are sent magnetic head (3,4) to gather train jointly and are formed axle information through out-of-date wheel information, as the condition of axis-counting device statistics wheel shaft.
