Description
Technical field
The present invention relates to a kind of irregular freight transportation noncontact displacement detector, particularly relate to the non-contact detection device adopting Hall element to carry out goods displacement, belong to measurement technical field of measurement and test.
Background technology
Freight transportation is the important component part of modern logistics, the freight transportation carried out especially by highway network and dispensing, one of two basic means of transportation forming land freight transportation, freight transportation due to climate and effect of natural conditions less, and movement capacity and bicycle charging capacity are greatly, occupy advantage, added polytype vehicle the regular of transport and low cost, make almost can carry any commodity, almost can not be subject to the restriction of weight and volume.
The height of freight transportation service quality is the arrival promptness rate of goods stock on the one hand, and information in transit is unobstructed is also embody service quality, promotes the important means of service experience; On the other hand, goods security in transit, reduction transport breakage rate are also the importances promoting service quality.
Freight transportation is in transit is in the information empty window phase, goods, by road transport vibration, goods damage situation occurs cannot be grasped and tracking is reviewed in real time, because the stacking of the acceptance of goods is different with arrangement, same checkout equipment cannot be adopted, in order to adapt to the dirigibility of freight transportation displacement detecting, it is a good technical solution that untouchable freight hold relative displacement detects.
Summary of the invention
In order to solve a prior art difficult problem, the invention provides a kind of irregular freight transportation noncontact displacement detector.Concrete technical scheme is:
Comprise some groups of detecting units and magnetic sheet, wherein detecting unit is made up of control circuit, wireless communication module, receiving circuit, driving circuit, hall probe, and battery-powered; Magnetic sheet is permanent magnet;
Detecting unit and magnetic sheet are installed on the opposite side cylinder of adjacent two goods buttress respectively, are goods buttress gap between detecting unit and magnetic sheet; The hall probe of detecting unit is just to magnetic sheet, and the distance in gap piled up neatly by goods, and the variable angle between hall probe and magnetic sheet causes the change of Hall voltage on hall probe, in order to detect the position skew between two goods buttress;
Wherein control circuit is connected with wireless communication module, receiving circuit, driving circuit; Hall probe is connected with receiving circuit, driving circuit; Control circuit is communicated with onboard wireless base station by wireless communication module, will detect data back after receiving instruction; When detecting startup, control circuit starts driving circuit, and driving circuit forms the electric current flowing through hall probe, under the influence of magnetic field that extraneous magnetic sheet is formed, produce Hall voltage, received circuit collection, after signal amplification, signal transacting, analog to digital conversion, be sent to control circuit.
In sum, the Advantageous Effects of technical scheme proposed by the invention is: adopt Hall element, the position skew between two goods buttress is detected by the change detecting the Hall voltage under extraneous magnetic fields, checkout equipment is non-contact design, simply flexible for installation, cost is low, can be optimized combination according to irregular goods packing, reduce the quantity of detecting unit, there are good application and market outlook.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of irregular freight transportation noncontact displacement detector of the present invention;
Fig. 2 is the circuit theory diagrams of a kind of irregular freight transportation noncontact displacement detector of the present invention.
Embodiment
With reference to accompanying drawing, describe the present invention below.
As shown in Figure 1, in a kind of irregular freight transportation noncontact displacement structure of the detecting device of the present invention, logistics flat pallet 100 is stacked with the first goods buttress 101, second goods buttress the 102, the 3rd goods buttress the 103, the 4th goods buttress the 104, the 5th goods buttress the 105, the 6th goods buttress the 106, the 7th goods buttress 107, each goods buttress has different Package sizes, in order to the loading space of efficiency utilization logistics flat pallet 100, improve the stability of sabot, each goods buttress intersects balancing arrangement in logistics flat pallet 100 loading plane;
Being subjected to displacement misalignment in transit to follow the tracks of each goods buttress, piling up neatly 107 to right lateral column face mounted in pairs first detecting unit 108 and the first magnetic sheet 109 at the first goods buttress 101 and the 7th goods; 103 relative lateral column face mounted in pairs second detecting units 110 and the second magnetic sheet 111 is piled up neatly at the second goods buttress 102 and the 3rd goods; Lateral column face mounted in pairs the 3rd detecting unit 112 and the 3rd magnetic sheet 113 of 107 is piled up neatly at the second goods buttress 102 and the 7th goods; Lateral column face mounted in pairs the 4th detecting unit 114 and the 4th magnetic sheet 115 of 107 is piled up neatly at the 6th goods buttress 106 and the 7th goods; Lateral column face mounted in pairs the 5th detecting unit 116 and the 5th magnetic sheet 117 of 104 is piled up neatly at the 5th goods buttress 105 and the 4th goods; Each detecting unit and magnetic sheet are arranged on the opposite face of adjacent goods buttress respectively, be contactless state between the two, according to making rational planning for, each detecting unit and magnetic sheet compared with uniform distribution on each goods of logistics flat pallet 100 is piled up neatly; Because mobile its contiguous goods of vibrations being transferred between each goods buttress on logistics flat pallet 100 is piled up neatly, therefore by the displacement detecting of contiguous goods buttress, self displacement can be traced into, therefore, each the contact side cylinder not needing each goods to pile up neatly installs checkout equipment, thus decreases the quantity of checkout equipment; Each detecting unit, by communication and onboard wireless base station communication, realizes the function obtaining instruction and return data.
As shown in Figure 2, the circuit of a kind of irregular freight transportation noncontact displacement detector of the present invention comprises: detecting unit 209 and magnetic sheet 205; Wherein detecting unit 209 is made up of control circuit 200, wireless communication module 201, receiving circuit 202, driving circuit 203, hall probe 204, and battery-powered; Magnetic sheet 205 is permanent magnet; Detecting unit 209 is arranged in goods buttress second 207, and magnetic sheet 205 is arranged in goods buttress first 206; It is goods buttress gap 208 between detecting unit 209 and magnetic sheet 205; The hall probe 204 of detecting unit 209 is just to magnetic sheet 205, the distance in goods buttress gap 208, and hall probe 204 and magnetic sheet 205 unilateral between variable angle cause the change of Hall voltage on hall probe 204, principle detects the position skew between two goods buttress according to this;
Control circuit 200 is connected with wireless communication module 201, receiving circuit 202, driving circuit 203; Hall probe 204 is connected with receiving circuit 202, driving circuit 203; Control circuit 200 is communicated with onboard wireless base station by wireless communication module 201, will detect data back after receiving instruction; When detecting startup, control circuit 200 starts driving circuit 203, driving circuit 203 forms the electric current flowing through hall probe 204, under the impact in the magnetic field that extraneous magnetic sheet 205 is formed, produce Hall voltage, received circuit 202 gathers, and after signal amplification, signal transacting, analog to digital conversion, is sent to control circuit 200; By physics knowledge, Hall voltage V
hsize be proportional to the product of drive current intensity I and magnetic induction density B, and the cosine of the space angle θ of magnetic induction density and hall probe 204 and magnetic sheet 205 relative area is directly proportional, and and distance h between hall probe 204 and magnetic sheet 205 be inversely proportional to, therefore have: V
h∝ IB cos θ/h.
