Method and system for checking loading compliance of fresh agricultural product transport vehicle

Abstract

The invention discloses a method and system for checking the loading compliance of a fresh agricultural product transport vehicle. According to the method and system, the theoretical density thresholdvalue of a fresh agricultural product cargo loaded on a to-be-checked vehicle is calculated according to the theoretical density determination models of fresh agricultural products; the theoretical weight threshold value of the compartment front load-bearing axle group of the to-be-checked vehicle loaded with the fresh agricultural product cargo is calculated according to the theoretical weight determination model of the compartment front load-bearing axle group of the to-be-checked vehicle; whether the actual density of the fresh agricultural product cargo loaded by the to-be-checked vehicleis within a theoretical density threshold range or not is judged according to a calculation result, and whether the actual weight of the compartment front load-bearing axle group of the to-be-checkedvehicle is within a theoretical weight threshold range is judged according to a calculation result; and when the actual density is within the theoretical density threshold range, and when the actualweight is within the theoretical weight threshold range, valid loading is carried out. With the method and system of the invention adopted, the frequency of opening the compartment of the vehicle andchecking the cargo by an inspector is reduced, the accuracy of the checking of the illegal loading of the fresh agricultural product transport vehicle is improved, and the working intensity of the inspector is reduced.

Description

technical field [0001] The invention belongs to the technical field of on-vehicle cargo detection, and in particular relates to a method and system for checking the loading compliance of fresh and live agricultural product transport vehicles. Background technique [0002] In 2009, the nationwide policy of exempting vehicles legally loaded with fresh agricultural products from tolls has created a favorable policy environment for reducing transportation costs and increasing farmers' income. According to the statistics of expressway network tolls in 23 provinces (autonomous regions, municipalities), the traffic volume of vehicles transporting fresh and live agricultural products accounted for 4.55% of the total traffic volume of expressway trucks in 2018, and the growth rate is gradually expanding. However, at present, in the "green channel" of the expressway toll station (or the entrance of the overtaking station), there is still the phenomenon of non-standard mixed transporta...

Problems solved by technology

[0004] Manual inspection method: adopt the method of touching and sniffing and cutting the goods to open the compartment inspection of the green pass goods. This method consumes a lot of energy and is easy to damage the goods. It requires high execution ability of the toll collectors and greatly affects the traffic efficiency.

[0005] Cargo perspective imaging inspection method: some provincial toll stations install cobalt-60 cargo perspective imaging equipment, and the purchase cost of a single device is estimated to be more than 1.5 million. Dose still needs to be rigorously justified

[0006] At present, the toll station still lacks a method and system for checking the loading compliance of fresh and live agricultural products transportation vehicles with low equipment cost, fast detection speed, accurate results and effective reduction of open compartment rate
