Problems solved by technology

It should be noted that whether pressure sensors, infrared sensors, laser scanning devices or radar detection devices are used, the cost is high, which will increase the cost, and these detection devices are easy to damage, which will correspondingly increase the number of failure points

Embodiment Construction

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0026] The method for detecting whether the object-carrying device is loaded or not provided by the embodiment of the present application utilizes the feature that the satellite signal received by the antenna on the carrying surface will be weakened when the object is loaded on the carrying surface, and is set at different positions of the object-carrying device. For the antenna receiving satellite signals, it is determined whether the loading device...

Abstract

Embodiments of the invention disclose a method, device and system for detecting whether a loading device carries out loading or not. A first antenna and a second antenna for receiving satellite positioning signals are arranged on the loading device; the first antenna is arranged on the outer surface of the loading device and is an external non-shielded antenna; the second antenna is arranged on the bearing surface of the loading device; and when the loading device carries out loading, the intensity value of the satellite signal received by the second antenna is decreased. The method comprisesthe steps of obtaining the signal intensity values of the satellite positioning signals respectively received by the first antenna and the second antenna; determining a difference value between the signal intensity values of the satellite positioning signals received by the first antenna and the second antenna; when the difference value is greater than a threshold value, determining the loading device in a loaded state; and when the difference value is smaller than or equal to the threshold value, determining the loading device in an unloaded state. The method, device and system are capable ofreliably detecting whether the loading device carries out loading or not at a relatively low cost.

Description

technical field [0001] The present application relates to the detection field, in particular to a method, device and system for detecting whether an object-carrying device is loaded. Background technique [0002] A trailer is usually a vehicle that is pulled by a tractor as a drive and has no power drive itself. According to the connection mode between the trailer and the tractor, the trailer can be divided into a full trailer and a semi-trailer. A full trailer is a trailer that is pulled by a tractor and all of its mass is borne by itself; a semi-trailer is a trailer that is towed by a tractor and part of its mass is borne by the tractor. No matter what kind of trailer has the advantages of mobility and flexibility, it is widely used in the logistics industry. [0003] Trailers can give full play to their advantages only after they are loaded. Therefore, it is of great significance to know whether the trailer is loaded with goods in time for the management and reasonable d...
