System Architecture and Solution Explanation
The intelligent cold storage temperature and humidity monitoring information management system is aimed at the needs of intelligent management of some large cold storage warehouses. A security system developed based on technology. The system has:
1) Flexible structure: The design of the intelligent cold storage management information system is based on the framework of the overall information planning, and adopts the “original model” structure to ensure the classification of data, control, business, and interface for future business development, 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 enhance efficiency and value.
3) Function customization: While satisfying the current cold storage business, the system provides function switches for integrated management of RFID and barcode technology, providing system guarantee for more refined management in the future.
4) Rich expansion: The system has realized some functions of “asset management, intelligent distribution, logistics management, office automation, information release and notification, and e-commerce”, laying the foundation for customers’ informatization application at a higher level in the future.
Operating mode
The tag works in an “active or passive way”. The tag actively emits a signal or is triggered by the reader’s instruction to emit a signal. The frequency of emission and temperature measurement is adjustable.
The tag detects the ambient temperature according to the predetermined frequency or the instruction of the reader and transmits the ID and temperature information to the reader. When the temperature exceeds the upper and lower limits, it can alarm through the built-in buzzer.
Recognition distance
The “active” positioning electronic tag can work with many of the company’s readers, and in specific applications, the signal strength and identification distance have very prominent characteristics. In a good visual environment, the recognition distance can reach 100 meters stably.
When the user has different requirements on the length of the maximum recognition distance, or the application environment is more complicated, the reader with different signal strength can be selected, and the sensitivity of the reader can be adjusted by the application software to achieve the required recognition distance.
