The key application of RFID smart granary lies in the perfection of the system and the coordinated operation of various functional management systems to be able to grasp the grain situation in real time.
一、Intelligent Outbound/Inbound System
The system integrates license plate intelligent recognition, ID card reading, IC card reading and writing, barcode printing/recognition, weighing and measuring equipment, LED display, video surveillance, handheld smart terminals and other equipment to realize intelligent entry registration, sampling, grain inspection, weighing The functions of checking catties, automatic pricing, automatic calculation of deductions, automatic settlement, online banking payment, etc., enable the entire process of grain out/in storage operations to be automated and visualized, eliminating human intervention.
二、Intelligent storage system
Relying on a variety of information technology methods, automatic detection of grain temperature, gas concentration in the granary, insect situation, etc., based on the detection results of the grain situation and external meteorological data, intelligent control of ventilation, air conditioning, and drying equipment, precise control of the granary environment, to achieve Intelligent grain storage goal.
三、Smart Security System
It provides functions such as monitoring camera access, picture preview, photographing, video recording, and grain data collection, analysis, and display. Relying on the intelligent security system, China Grain Storage Corporation can penetrate and view the real-time information of any warehouse point within its jurisdiction to realize visual supervision.
四、Food Monitoring System
Through the deployment of video monitoring equipment and grain condition sensing equipment in the grain depot, it automatically captures images of key operation points and grain storage conditions in the grain depot every day, and uploads them to the database for archiving, providing audit supervisors with more audit information. The system can also provide physical measurement and replenishment calculation services, using laser scanning technology to calculate the volume of grain piles; combine the bulk density of the grain to calculate the quantity of grain in the warehouse, and then calculate the replenishment quantity based on the inventory quantity and warehouse capacity.
五、Safety assurance system construction. Including the following 3 aspects.
① Data security, encrypted storage protection of key data of the grain situation, and supports multiple encryption algorithms.
② Network transmission security, the key data of grain situation is transmitted using encryption protocol to ensure that it is not monitored during transmission.
③ Application access security, issuance of digital certificates for users who use smart storage/warehousing, smart storage, smart security, food monitoring and other systems, and bind the user’s identity with the digital certificate to achieve accurate identification of the identities of both parties in network information transmission; Restrict the application functions that users can access by setting permissions; provide security log auditing.
Through the implementation of the smart granary project, China Grain Storage can accurately grasp the national grain inventory quantity, inventory distribution and grain status, and remotely and real-time view the on-site situation of the granary. The period for the state to grasp the grain situation has been shortened from the original 15 days to 3 days. Based on the grasp of real-time grain conditions, China Grain Storage is able to accurately carry out storage operations such as fumigation, air conditioning, and ventilation to avoid grain aging and extend the grain storage cycle. The project also reduced the loss of grain purchase and storage caused by objective or human factors, and reduced energy consumption and labor costs by about 5%.
