The specific embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5:
The utility model is a kind of railroad train axle-counting device; It comprises detection module 10, magnetic head sensor 20 and meter axle main frame 30; Described detection module 10 comprises interconnective Voltage-Controlled oscillation circuit 101, frequency selection circuit 102, amplifying circuit 103, acceptor circuit 104, waveform combiner circuit 105, filter circuit 106 and comparator circuit 107; Described magnetic head sensor 20 comprises transmission magnetic head 50 and receives magnetic head 60; Send magnetic head 50 and receive the left and right sides that magnetic head 60 is separately positioned on rail 40; Detection module 10 is supplied with transmission magnetic head generation alternating flux through the square wave that Voltage-Controlled oscillation circuit 101, amplifying circuit 103 produce CF; Detection module 10 passes through frequency selection circuit 102, filter circuit 106 and amplifying circuit 103 and receives the alternating flux signal from transmission magnetic head 50 of handling 60 inductions of reception magnetic heads, and detection module 10 receives these alternating flux signals and exports to a meter main frame 30 in order to analyze and a demonstration meter axle situation through pulse.
Above-mentioned transmission magnetic head 50 produces alternating flux, and process EM coupling and reception magnetic head 60 interlinkages induce with the frequency AC signal at reception magnetic head 60.
Above-mentioned meter axle main frame 30 is an intelligent computer.
An above-mentioned detection module 10 sends magnetic heads 50 and cooperates and produce alternating flux respectively and receive magnetic heads 60 and cooperates two groups of alternating flux signals that receive 50 generations of two transmission magnetic heads respectively with two simultaneously with two; And respectively forming a signal element through pulse output, the two group pulse output signals that two signal element will receive respectively are transferred to meter axle main frame 30 in order to analyze and to show that vehicle is in the situation in the meter axle zone through the meter shaft cable.
The principle of work of the magnetic head sensor 20 of the utility model:
Send alternating flux φ 1 and alternating flux φ 2 that magnetic head 50 produces, induce hundreds of millivolts of same frequency AC signals at reception magnetic head 60.
The principle of work of the utility model when train process magnetic head sensor 20:
Do not having Train Wheel to when the magnetic head sensor 20, it is constant to receive signal magnitude.When Train Wheel when getting into the sphere of action of magnetic head sensor 20, the signal amplitude (or phase place) in the reception magnetic head 50 of magnetic head sensor 20 changes.The signal of this variation sends to detection module 10, through processing to produce with each wheel that passes through to 70 a corresponding meter pulse, reflect to counting then.Service direction is different, and wheel is different through the priority of two sensors to 70, after being differentiated by meter axle main frame 30, confirms the number of axle is carried out accumulated counts or countdown.When a wheel of train passed through magnetic head sensor 20 to 70, detection module 10 detected the signal variation and produces pulse, and sent pulse to a meter axle main frame; Meter axle main frame compares computing with the wheel that sails out of section to 70 number of axle to sailing section into simultaneously then; And the control area section takies relay; Only when two adjacent groups sensor meter axle operation result is zero; This section takies relay and just can fall, thereby provides the expression of this section cleared, otherwise the interval still is in seizure condition.
The foregoing description is merely one of preferred embodiment of the utility model, is not the practical range that limits the utility model with this, so the equivalence that all shapes according to the utility model, structure, principle are done changes, all should be covered by within the protection domain of the utility model.
