Smart tag-based grain ex-warehousing and warehousing operation supervision method and system

Abstract

The invention discloses a smart tag-based grain ex-warehousing and warehousing operation supervision method and a system. The method comprises the steps of generating a trigger signal by a communication trigger to trigger an RFID tag arranged in a vehicle within a predetermined range around the communication trigger so as to enable the RFID tag to upload identification data to an application server via a wireless base station; positioning the vehicle by the application server according to the identification data; judging whether the operation process of the vehicle meets the requirement or not based on the position of the vehicle; and sending a switching-on control signal to a belt conveyor power control box on the condition that the position of the vehicle meets the requirement. A belt conveyor connected with the belt conveyor power control box is automatically switched on by the belt conveyor power control box according to the switching-on control signal. According to the technical scheme of the invention, the long-distance communication between the tag and the base station is realized. Meanwhile, the method and the system are used for dynamically tracking and positioning grain-conveying vehicles and monitoring the operation processes of the vehicles.

Description

technical field [0001] The invention relates to an RFID-based grain depot management system, in particular to a method system for supervising grain in and out of the warehouse based on smart labels. Background technique [0002] The informatization level of my country's grain industry and food system has always been relatively low, especially the development of informatization in the management of grain storage and storage is uneven, and the adjustment and reform of the grain system in recent years have made the original information supervision infrastructure no longer suitable for the new Information collection is scattered, multiple facilities coexist, interfaces and exchanges are independent, standards are not uniform, and information islands are serious. [0003] Existing grain circulation enterprises mainly rely on manual arrangement, manual command, manual supervision, and manual recording during the execution of grain storage and storage operations. There are many pro...

Problems solved by technology

[0006] However, this technology has certain limitations. The RFID card installed on the vehicle must be within the effective distance of the reading module. However, the effective distance is usually limited, and there may be a disadvantage that it cannot be obtained.

At the same time, RFID can only identify the vehicle but does not supervise the operation process of the vehicle. There may be a phenomenon that the vehicle does not operate according to the formal process to steal food.
