Known via above-mentioned technical scheme, compared with prior art, present disclosure provides a kind of traffic flow detecting device.This device is by being arranged on geomagnetic sensor on track and acceleration transducer detects vehicle flowrate.Concrete, when processor determines that the geomagnetic sensor on certain two track senses GEOMAGNETIC CHANGE simultaneously, and the vibration frequency that senses of the acceleration transducer on above-mentioned two tracks identical time, processor determines that by the vehicle in above-mentioned two tracks be same vehicle, then vehicle flowrate adds 1, avoid to vehicle repeat statistics, improve the accuracy of detection of vehicle flowrate.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 shows the structural representation of an embodiment of a kind of traffic flow detecting device of the present invention;
Fig. 2 shows the structural representation of an embodiment of a kind of traffic flow detecting device of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The structural representation of an embodiment of a kind of traffic flow detecting device of the present invention is shown see Fig. 1.As shown in Figure 1, in this present embodiment, this device comprises: multiple geomagnetic sensor 1, multiple acceleration transducer 2 and the processor 3 be connected with multiple acceleration transducer 2 with multiple geomagnetic sensor 1.
Wherein, when the plurality of geomagnetic sensor 1 is respectively used to detect vehicle by each track, the GEOMAGNETIC CHANGE around each track.
When multiple acceleration transducer 2 is respectively used to detect vehicle by each track, the shock conditions in each track.
Due to different vehicles by identical track time, the vibrations on the ground caused are different, and thus processor 3 can according to the vibrations on ground, judge whether be same vehicle by the vehicle in multiple track (such as two tracks, left and right) simultaneously.
The Cleaning Principle of this vehicle detection apparatus is introduced below for track, two, left and right
Left-lane arranges the first geomagnetic sensor and the first acceleration transducer respectively, right lane arranges the second geomagnetic sensor and the second acceleration transducer.
When vehicle is by left-lane, because vehicle can regard the model of multiple bipolar magnet composition as, thus causing the change of track ambient magnetic environment, being arranged on the first geomagnetic sensor on left-lane for detecting this GEOMAGNETIC CHANGE.When simultaneously different vehicles is by track, the vibrations that track produces are different, are arranged on the first acceleration transducer on left-lane for detecting the shock conditions in track in real time.
In like manner, vehicle is through right lane, and the second geomagnetic sensor is identical with the Cleaning Principle of the second acceleration transducer.
When rule-breaking vehicle travels in two tracks, left and right, first geomagnetic sensor second geomagnetic sensor all senses GEOMAGNETIC CHANGE, and then the shock conditions that processor detects according to the first acceleration transducer and the second acceleration transducer, judge whether by the vehicle in two tracks, left and right be same vehicle.Concrete, when the first geomagnetic sensor and the second geomagnetic sensor detect GEOMAGNETIC CHANGE simultaneously, and the first acceleration transducer identical with the vibration frequency that the second acceleration transducer detects time, processor determines that by the vehicle in two tracks, left and right be same vehicle, thus add 1 on the basis of original vehicle flowrate, avoid to vehicle repeat statistics, improve the accuracy of detection of vehicle flowrate.
It should be noted that, due to different load-carrying vehicle caused by the amplitude of track vibrations different, thus processor also according to the relation of the vibration amplitude pre-set and vehicle load, can determine the load-carrying of vehicle.
In the application of reality, because bicycle (bicycle) and non-vehicle (magnet) are in the change by causing earth magnetism during track equally, thus in order to avoid the impact of the factor such as bicycle and non-vehicle, processor also for according to vibrations time and vibrations number of times, determines whether described vibrations belong to the track vibrations of vehicle by causing during track.
In order to strengthen vehicle-mounted heavy monitoring, avoid the breaking-up that overloaded vehicles causes track.The structural representation of another embodiment of a kind of traffic flow detecting device of the present invention is shown see Fig. 2.With a upper embodiment unlike, in the present embodiment, this device comprises: geomagnetic sensor 1, acceleration transducer 2, the processor 3, camera 4 and the server 5 that are connected with acceleration transducer 2 with geomagnetic sensor 1.
Wherein, when processor 3 is determined to be more than the default load-carrying in this track by the load-carrying of the vehicle in certain track, processor 3 controls camera 4 and takes pictures to this overloaded vehicle, stores being sent in server 5 by photo by wired or wireless communication.Such law enfrocement official by the relevant information in corresponding terminal downloads server 5, thus punishes vehicle in violation of rules and regulations.
Finally, also it should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operational zone, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ...
