RFID technology creates intelligent entry and exit of grain warehouses

With the rise of "Internet +" technology, the food field is gradually moving towards informatization and electronics. Improving the management efficiency of grain depots through informatization has been increasingly valued by the state and grain storage enterprises. Therefore, the concept of "grain depot information construction" emerged at the historic moment. The construction content of the grain depot information system is divided into four business domains: "grain depot business management", "intelligent entry and exit", "intelligent warehousing and storage", and "intelligent security". This article mainly provides an upgraded solution for "intelligent entry and exit" plan. RFID technology creates intelligent entry and exit of grain warehouses.

1. Current status and problems of traditional storage methods for grain depots

The procurement, storage and sales of grain are not only the core business of the grain depot, but also a difficulty in supervision. Especially during the peak harvest season, manual operations often have many disadvantages, such as irregular processes and many blind spots in supervision, which are mainly reflected in the following three points:

1. Data is recorded manually and information is not shared.

Manual filling of documents in each link makes it difficult to avoid mis-filling or human tampering, which encourages illegal activities such as "favor food" and leads to inconsistencies in information in the previous and subsequent links, discrepancies between accounts and facts, and distortion of quantity and quality, etc.;

2. Grain trucks are not supervised one by one, and information is not recorded in real time.

The trajectory of grain delivery vehicles cannot be continuously monitored throughout the entire process. There are blind spots, making it difficult to prevent cheating such as quantity manipulation during the entry and exit process. At the same time, information on each link of each vehicle cannot be recorded in real time, and weighing, quality inspection, loading and unloading cannot be traced at any time. , grain payment settlement and other information, even if the grain depot requires statistical analysis, auditing and supervision, there is a lack of true and accurate data, making cheaters emboldened;

3. Automation has not been realized, and it is difficult to maintain fairness in human supervision.

Not only is manual operation inefficient, but the person-to-person supervision method is driven by profit. This results in irregular warehousing and warehousing procedures, inadequate implementation of national policies and standards, and problems such as difficulty in selling grain and low quality of warehousing grain.

The above reasons make it common for grain harvesting to "check one and sell another", "swap cars and return hides", "change license plates", "sneak samples" and other phenomena, which in the long run will bring immeasurable losses to the country and grain storage enterprises.

2. Intelligent entry and exit based on “all-in-one card”

Based on the above problems, the paperless office method represented by the "Grain Depot Card" has emerged. The Grain Depot Card is made into a card similar to the size of a bank card, and the vehicle, personal and other information related to the grain seller is associated with the card. Here, with this card, grain selling customers can complete the entire process of entry registration, sampling, weighing, loading and unloading confirmation, weight deduction, settlement and payment, and grain transactions, making the purchase and sales of grain depots the first to enter the information age. But its essence is to replace the original work of manually filling in paper documents and achieve the initial stage of informatization - paperless.

But this card can be exchanged between two vehicles just like "exchanging license plates", so there are still big loopholes from a regulatory perspective.

3. Magnetic vehicle electronic tag application upgrade intelligent entry and exit solution

Active monitoring magnetic vehicle electronic tags are low-power, multi-band electronic tags that are highly integrated and have wireless communication, RFID functions, pressure detection, magnetic field detection and other functions. It is compatible with applications such as all-in-one card, license plate recognition, QR code, and disposable electronic labels, realizing the dual functions of electronic communication and vehicle supervision.

The magnetic vehicle electronic tag cannot be separated from the vehicle. It is adsorbed on the vehicle when the grain truck enters the factory. Intelligent identification terminals are installed in all aspects of sampling, inspection, weight inspection, warehousing, etc. to automatically identify vehicle information and complete automatic information interaction. , to achieve automatic association between grain trucks and samples, inspection results, and weighing results. Grain trucks are tracked step by step, so that artificial interference and cheating methods such as changing trucks to return skins, secretly changing samples, inspecting one and selling another, etc., have nowhere to hide.

At the same time, vehicle electronic tags can monitor pressure and magnetic field strength. That is, once the tag is moved or removed, an audible and visual alarm can be issued on the intelligent interactive terminal to terminate the vehicle's food sales and realize all vehicle-borne items such as food data ( Quality, weight) are uniquely related to the seller's information, eliminating the possibility of cheating from the root, and realizing active monitoring of vehicles and people.
