Dual-frequency communication based intelligent management method and system of weight measurement

Abstract

An embodiment of the invention provides a dual-frequency communication based intelligent management method and system of weight measurement. The method mainly includes the steps: after a vehicle arrives at a positioning node area in a weight measurement area, a dual-frequency positioning communication device arranged on the vehicle receives a low-frequency signal transmitted by a dual-frequency positioning node device arranged on a positioning node, the dual-frequency positioning communication device transmits a high-frequency signal to a communication base station device, and after the fact that a weight measuring process of the vehicle at the positioning node is legal is determined according to stored information about the weight measuring process of the vehicle, the communication base station device informs the dual-frequency positioning node device of allowing the vehicle to finish the weight measuring process related to the positioning node. The method and the system according to the embodiment have the advantages that positioning and communication ranges can be flexibly set according to specific environments of weight measurement areas such as a grain depot, incorrect and missing pieces of positioning and communication data are effectively avoided, and interference among various communication signals can also be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of weight measurement, in particular to a method and system for intelligently managing weight measurement based on dual-frequency communication. Background technique [0002] In the process of grain warehousing, there are many regulatory loopholes in the manual control of grain in and out, storage and storage. For example, weighing on the weighbridge is an important business of grain warehousing in my country. There are many fraudulent behaviors in the process of weighbridge weighing, such as: the vehicle is not fully weighed when entering the warehouse, weighed multiple times, the license plate is changed, the vehicle is pressed, etc.; These behaviors have caused great losses to the grain storage business and have had a major impact on national food security. [0003] At present, there is no effective management system for the management of mobile equipment in the warehouse area. Some solutions proposed at...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: it is not only expensive when commonly used, but also highly dependent, completely relying on the GPS navigation system

Since the special data information of the grain depot cannot be transmitted, the communication with the host computer and terminal detection equipment (such as weighing equipment, etc.) is also difficult to realize

Moreover, it can only realize the positioning of vehicles, but cannot perform process management and control, and cannot meet the requirements of the grain depot management system
