Embodiment Construction

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing function and circuit communication function.

[0042] It is to be understood that the terms "length", "width", "top", "bottom", "front"...

Abstract

The invention provides a high-precision vehicle-mounted area weighing method. The high-precision vehicle-mounted area weighing method comprises the following steps: obtaining a strain gauge value installed on a vehicle axle; dividing a weighing area, and dividing the weighing area into at least two sub-areas; sequentially loading a test standard weight in each sub-region to obtain a vector formedby the weight of the test standard weight in each sub-region and a matrix formed by corresponding strain gauge values; adopting KNN modeling to identify the subarea where the current weighed goods arelocated; and establishing a mapping relationship between the strain gauge value and the actual weight by utilizing Gaussian process regression according to a vector formed by the weight of the test standard weight of each sub-region and a matrix formed by the corresponding strain gauge value. The weighing precision reaches 1.5%, high-precision vehicle-mounted weighing is realized in the true sense, and the precision requirement of the current logistics industry on vehicle-mounted weighing is completely met. The unbalance loading problem caused by a common vehicle-mounted weighing scheme is completely overcome.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted area weighing, in particular to a high-precision vehicle-mounted area weighing method. Background technique [0002] The collection and delivery vehicles in the logistics industry all use 4.2m models, such as JMC, Yuejin, and Dongfeng. At present, several major logistics companies, such as YTO, Debon, and Leapfrog, have tens of thousands of vehicles of this type. [0003] At present, the logistics industry adopts electronic scales or weighbridges to measure the weight of goods when receiving and delivering goods. The electronic scale carried by the vehicle has obvious disadvantages such as small range, easy loss, and small weighing volume, while the weighbridge can only be weighed in the field of collection and transportation, and cannot be weighed at the customer's site. The large logistics items sent by mail are transported back to the field to be weighed and billed, and then the bill i...
