Method and device for calculating space loading rate of carriage

Abstract

The invention provides a method and device for calculating the space loading rate of a carriage, and the method comprises the steps: building a carriage XYZ-axis coordinate system, enabling a Z axis to be the distance direction of infrared distance measuring sensors, enabling the infrared distance measuring sensors to be arranged in the distance direction, and enabling the infrared distance measuring sensors to carry out the distance measurement sampling in the carriage; s2, constructing a triangulation network segmentation space according to the sampling values of the infrared distance measuring sensors on the Z axis, performing linear interpolation on the space by using the sampling values on the Z axis, and constructing a plurality of minimum triangulation networks on XY coordinates ofthe coordinate point set established in the step S1; calculating the volume of each minimum triangulation network by using a double definite integral method; traversing all the minimum triangulation networks obtained through segmentation, summing the volume of each minimum triangulation network, calculating the carriage volume, and calculating the cargo volume according to the carriage volume. Theinvention is high in calculation efficiency, real-time calculation can be achieved, and calculation precision is more accurate than that of a manual mode.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a method and a device for calculating the loading rate of a carriage space. Background technique [0002] At present, the domestic logistics and transportation industry is booming, among which road truck transportation has the following characteristics: ① fast transportation speed; ② high reliability, less damage to products; ③ high mobility, you can choose different driving routes, and flexibly formulate operating schedules , so the service is convenient, door-to-door service can be provided, and the market coverage is high; ④ less investment and high economic benefits. Because transportation companies do not need to own roads, their fixed costs are very low, and the turnover of road transportation investment is fast; ⑤ Operators are easy to train. Therefore, road truck transportation is an important mode of transportation. However, due to its high mobility and...

Problems solved by technology

[0003] However, there is no intelligent system that can automatically identify the loading volume, especially during transportation, it is impossible to judge whether there is an abnormal loading and unloading event, and when the team settles the remuneration based on the volume of the transported goods, it can only be estimated by humans. The measurement method cannot be quantified, and it is too subjective to cause large errors
