With the development of science and technology and informatization, traditional management methods can no longer meet the requirements of higher management departments, customers and production for grain storage management. For example, traditional management methods make it impossible to achieve unique and real-time data in and out of the grain depot. The company and the grain depot are divided into two places, especially the business department, warehousing department, and storage point of large enterprises. , The decentralized layout of sales points makes the company unable to grasp the dynamics of grain circulation in time; in order to meet the needs of all parties and avoid data errors, the grain depot can only repeat the input of documents and check, which increases the workload of many operators and functional departments. Hope to reduce the workload of operation and expense settlement; farmers and customers want to speed up settlement and payment, etc.
Like the internals of some medium-sized storage systems, the management of grain enterprises is mostly in a non-automated, paper-based system to record and track incoming and outgoing grain. Due to the manual accounting method, the internal management of the warehouse and the acquisition of grain data are not timely, and the error rate is high; the operation process of grain in and out of the warehouse is relatively random, and it is difficult to standardize the management of railways, ports, and highways. Information cannot be shared. The uncertainty of human factors leads to low labor efficiency and serious waste of human resources. At the same time, with the increase in the quantity of grain and the sharp increase in the frequency of in and out of the warehouse, this mode has seriously affected the normal operation efficiency. Moreover, these warehouses and related third-party grain logistics centers have not established an overall grain storage information system from the production area to the transfer area to the sales area, which makes the storage information in the entire grain logistics supply chain unable to play an important role as a node, which seriously affects The operational efficiency of the entire grain enterprise.
In short, in the management of food enterprises, there are many statistics, duplication of labor, mismatches in numbers, and untimely feedback. Modern logistics and food modern logistics The development of modern logistics in our country began after the reform and opening up. Since the beginning of this century, it has become a hot spot in economic development. Among them, the development of modern logistics based on traditional transportation and warehousing methods is the main method or trend of the current development of logistics enterprises in my country. According to the national standard of “Classification and Evaluation Index for Logistics Enterprises” approved and issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China and the Standardization Administration of the People’s Republic of China, it is pointed out that warehousing logistics enterprises should meet the following four requirements at the same time: ①Mainly engage in warehousing business and serve as customers Provide goods storage and storage, transit and other warehousing services, with a certain scale: ②The company can provide customers with distribution services, commodity distribution, circulation processing and other services; ③The company has its own storage facilities and equipment of a certain scale. It owns or rents necessary freight Vehicles; ④With networked information service functions, the application information system can query and monitor the status of the goods.
It can be seen from this that the development of a warehousing-based enterprise to a warehousing logistics enterprise is to increase the radiation capacity of processing, packaging, handling, handling and other businesses on the basis of the main business of warehousing services. Through the use of information technology, we can provide customers with integrated services and increase customer satisfaction, thereby realizing the benefits of the company. Grain, as a special commodity related to the national economy and people’s livelihood, has its particularity in management. For grain warehousing and logistics enterprises, improving their management efficiency is also very important. Grain circulation has the characteristics of large volume, many points, wide coverage, frequent turnover, and strong timeliness. Grain is an important commodity related to the national economy and people’s livelihood, and it occupies an important position in the entire commodity logistics. According to statistics, grain logistics ranks seventh in the country’s transportation volume of various materials, and cargo turnover ranks second (statistics in 1997). According to relevant data, my country’s current grain output is 500 million tons, and the circulation is 1.7 billion tons, of which 85 million tons need inter-provincial long-distance transportation, 35 million tons need inter-provincial long-distance transportation, and 135 million tons are circulated and consumed within the region. In the two major systems of the grain storage and storage industry (grain storage system and turnover storage system), turnover grain accounts for 75% of the national stock of grain, and its turnover is frequent, which requires high turnover speed and efficiency. How to change the phenomenon of long-term statistics and repetitive labor numbers that do not match the feedback in time, and to solve the high requirements of modern grain logistics for grain in transportation, storage, loading and unloading, packaging, circulation, processing, and distribution, has become an urgent need to solve primary issue.
When analyzing the causes of each problem, one of the common and important factors can be found that the information in each link and business has not been shared to the greatest extent. But to realize the information sharing in the whole grain supply chain management. The application of RFlD technology is undoubtedly the best solution.
Feasibility analysis of the application of RFID technology Because RFID tags can uniquely identify products, they can be tracked in all aspects of logistics through the combination of computer technology, network technology, database technology, etc., and the dynamic information of the product can be grasped in real time. The application of this technology can achieve the following goals and obtain the expected benefits: ① Shorten the operation time. ② Improve the quality of inventory operations. ③Increase the throughput of the distribution center. ④Reduce operating costs. ⑤Realize visual management. ⑥ The transmission of information is faster and more accurate.
RFID technology uses radio waves to transmit identification information in large quantities at the same time in a non-contact, long-distance, and dynamic multi-target manner, realizing one item, one code, and rapid item tracking and data exchange. Because RFID technology eliminates manual intervention in the tracking process, it can greatly improve work efficiency while saving a lot of manpower.
