Problems solved by technology
[0004] The cargo transportation is in the information empty window period, and the cargo damage caused by the vibration of the road transportation cannot be grasped and tracked in real time. Because the stacking and arrangement of the cargo are different, the same testing equipment cannot be used. In order to adapt to the displacement detection of the cargo transportation Flexible, non-contact relative displacement detection between goods is a good technical solution

Embodiment Construction
[0012] Referring to the accompanying drawings, the present invention will be described in detail below.
[0013] Such as figure 1 As shown, in the structure of a non-contact displacement detection device for irregular cargo transportation in the present invention, the first cargo stack 101, the second cargo stack 102, the third cargo stack 103, the fourth cargo stack 104, The fifth stack 105 , the sixth stack 106 , and the seventh stack 107 each have different packaging sizes. In order to efficiently utilize the loading space of the logistics flat pallet 100 and improve the stability of the tray, each stack is cross-balanced Arranged on the logistics flat pallet 100 loading plane;
[0014] In order to track the displacement and misalignment of each stack during transportation, the first detection unit 108 and the first magnetic sheet 109 are installed in pairs on the side cylinders of the first stack 101 and the seventh stack 107; The second detection unit 110 and the second...

The invention discloses an irregular goods transport non-contact displacement detection apparatus comprising several sets of detection units and magnetic sheets. Each detection unit is composed of a control circuit, a wireless communication module, a receiving circuit, a drive circuit and a Hall probe, and is supplied with power by a battery. The magnetic sheets are permanent magnets. According to the invention, a Hall element is employed; and position offset of two goods stacks is detected by means of detecting changes of a Hall voltage under the effect of an extraneous magnetic field. The detection apparatus is of non-contact design; the installation is flexible and simple; the cost is low; optimized combination can be carried out according to irregular goods packages; the quantity of the detection units is accordingly reduced; and a good application and market prospect is realized.
Description
technical field [0001] The invention relates to a non-contact displacement detection device for irregular cargo transportation, in particular to a non-contact detection device using Hall elements for cargo displacement, and belongs to the technical field of measurement and testing. Background technique [0002] Cargo transportation is an important part of modern logistics, especially the transportation and distribution of goods through the road network. The large transportation capacity and single-vehicle loading have advantages in the frequent and low-cost transportation. In addition, there are various types of vehicles, which make it possible to carry almost any commodity without restrictions on weight and volume. [0003] On the one hand, the quality of cargo transportation services depends on the timely arrival rate of freight vehicles, and smooth in-transit information is also an important means to reflect service quality and improve service experience; on the other han...
