1. System significance
The traditional cold storage management system generally relies on a non-automated paper document-based system to record and track incoming and outgoing goods. The internal management of the cold storage is completely implemented manually. Therefore, the cold storage management is low in efficiency, small in scale, and large in errors. high cost!
At present, with the increase in the scale of cold storage, most companies have begun to use computer data system management in cold storage management, but data is still collected and statistically organized by first recording on paper and then manually inputting it into the computer. This not only causes a lot of waste of human resources, but also due to human factors, the data entry speed is slow, the accuracy rate is low, and the existence of forged data!
CurrentlyRFIDTechnology is bringing a huge change to the refined management of cold storage, to identify the advantages of long distance, fast, not easy to damage, large capacity, etc., simplify the complicated work process, and effectively improve the management efficiency and business transparency.
Introducing RFID technology combined with innovative Internet of Things applications, the cold storage warehouse “temperature and humidity monitoring, arrival inspection, warehousing, outgoing, allocating, shifting, shifting, inventory counting” and other operations for refined and intelligent management, Promote a variety of innovative profit models, save operating costs, improve service quality, increase business revenue, and help you achieve refined and intelligent cold storage management.
2. System architecture and program description
The intelligent cold storage temperature and humidity monitoring information management system is Shanghai Tangyuan Electronic Technology Co., Ltd. for the intelligent management of some large cold storage warehouses. It uses the most advanced RFID radio frequency identification technology, temperature and humidity sensing technology, and monitoring technology in the world today. , Communication technology, RTLS real-time positioning technology based on the development of a security system. The system has:
1) Flexible architecture: The design of the intelligent cold storage management information system is based on the overall information planning framework and adopts the “original model” structure to ensure the classification of data, control, business, and interface for future business development and system expansion. External system access provides structural support.
2) Mature technology: Combine the entire warehouse management with radio frequency identification technology to ensure that the system can efficiently complete various business operations, improve warehouse management, and increase efficiency and value.
3) Function customization: While meeting the current cold storage business, the system provides functional switches for the integrated management of RFID and barcode technology to provide system guarantees for more refined management in the future.
4) Extensive expansion: The system has realized some functions of “asset management, intelligent distribution, logistics management, office automation, information release and notification, and e-commerce” to lay the foundation for future customers’ higher-level informatization applications.

We install RFID wireless temperature, temperature and humidity sensors on the items or substances that need to monitor temperature, temperature and humidity in the cold storage warehouse. The sensor collects the temperature, temperature and humidity of the site in real time, and at the same time passes the collected data through 2.45G RFID The radio frequency signal is transmitted, and it is installed in the nearby 2.45G long-distanceReaderThe data is collected, and the signals are uploaded to the management center software system through various signal transmission modes. The software system can display the temperature, temperature and humidity changes of the items in the cold storage warehouse in real time; our management center software system is networked across the country, as long as At any place where you can access the Internet, you can log in with your username and password to observe the temperature, temperature and humidity changes on the cold storage warehouse anytime and anywhere; the system can also call the temperature, temperature and humidity changes records of the warehouse during a certain period of time, and it has Alarm function. When the warehouse temperature, temperature and humidity exceed the specified range, the system will send out an alarm signal to remind the management staff to deal with it in time. The alarm signal has many forms, such as on-site sound and light alarms, mobile phone text messages, etc.
