Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1; A kind of wireless axle-counting device; Comprise the axle count sensor (20,21), wireless receiving antenna 30, wireless transmission antenna 40, signal processor 50, DC power supplier 60, programmable control module 70, the transformer box that are installed on the railway track 10.These two axle count sensors (20,21) are fixed on the inboard of rail through binding bolt, respectively with signal processor 50 be electrically connected, DC power supplier 60 links to each other with signal processor 50, is used to signal processor 50 working power is provided.Programmable control module 70 is electrically connected with signal processor 50, and signal processor 50 is sent to programmable control module 70 with the impulse singla of handling well through wireless transmission antenna 40 and wireless receiving antenna 30; Transformer box is installed in 1.5 meters of railway track 10 1 sides, and wireless transmission antenna 40 is installed in the outer wall of transformer box; Signal processor, signal processor 50 are installed in the transformer box.Signal processor 50 can adopt the existing integrated circuits plate, can adopt commercially available product.Programmable control module 70 also can adopt the commercially available prod, and the PLC of general select tape counting module adopts SIEMENS FM350-1 like counting module, is used in SIEMENS S7-300 or the M7-300 control system, forms the PLC of band counting module.
The measuring cell of this device is by axle count sensor, thereby the railway car team provides one to measure impulse singla through rail level axle count sensor cutting magnetic field.After this measurement impulse singla carried out technical finesses such as shaping, self-locking, distortion, frequency division through signal processor, the feedback speed signal (square wave) that output one is isolated was sent into programmable control module, and programmable control module just can obtain the number of axle.Be communicated to the message scheduling expert system to the data that read and analyze, save as basic data.
Principle of work is following: during the utility model is wireless axle-counting device place in operation; Present the 5000Hz constant-amplitude signal of 20-30V through axle count sensor to sending magnetic head by indoor system controlled by computer; Send magnetic head and produce corresponding alternating flux; Through EM coupling and reception magnetic head interlinkage, so in accepting magnetic head, induce with AC signal frequently.This signal is sent indoor microcomputer back to through cable, the wheel that does not have train to through the time, it is constant to receive signal magnitude; Have Train Wheel to through the time, the signal amplitude that then receives in the magnetic head changes, the signal of this variation is sent indoor microcomputer back to; Will produce with each wheel that passes through to the pulse of corresponding meter axle; Differentiate direction and stored count then, the service direction of train is different, then takes turns the sequencing through two axle count sensors different; After the automatic discriminating of microcomputer, definite meter number of axle adds up or successively decreases.
