I. Overview
The RFID-based multi-scene temperature and humidity detection solution is a service platform that uses RFID radio frequency identification technology, sensor technology, wireless communication technology, GPS positioning and cloud database integration. Realize the traceability management of the whole temperature and humidity detection and tracking positioning of cold storage, cold chain logistics equipment (refrigerated trucks, freezers, refrigerated containers) and goods, and the binding of RFID and goods to achieve logistics in and out, inventory, sorting, and reverse transportation Intelligent operation is an ideal tool to realize the temperature and humidity detection and intelligent operation of cold chain logistics;
The temperature and humidity active tags and readers independently developed by Zhongke Cloud Control, as well as the corresponding cloud service platform, can effectively solve the temperature and humidity monitoring problems in the storage, transportation, and sales links of products with high temperature and environmental requirements.
2. Introduction to application requirements
The above picture shows the demand for temperature monitoring in the production, transportation, storage and sales of fresh food, medicine and other products, and shows the role of active RFID tags with temperature and humidity sensing technology in this process. It can not only It can reflect the temperature and humidity of the item environment in real time, and it is very convenient to collect information. It effectively forms a complete system to help detect the temperature and humidity of the environment. It can also perform intelligent management, transportation and storage of products, and truly realize temperature monitoring and product management. Intelligent.

3. Introduction to the temperature and humidity monitoring program of Zhongke Cloud
The RFID-based temperature and humidity monitoring program consists of a five-layer architecture, which are the terminal sensing layer, the network transmission layer, the middleware application layer, the cloud platform, and the application layer. The terminal sensing layer is composed of various active RFID tags with sensors and storage. At present, Zhongke Cloud Control has developed 2.4G temperature tags T40 tags, T35 tags, and T20 tags based on the lora protocol, which can monitor -40~ Temperature range of 80°C. The network transmission layer contains various data reading devices. At present, Zhongke Cloud Control has developed readers R11 and TR20 for serial port 485 communication, readers R61 for wifi communication, and R62 for GPRS communication. At the middleware layer, Zhongke Cloud Control has designed and developed an edge server to preprocess and clean the reader data, which greatly reduces the amount of network data transmission and the burden of the cloud server. In the application layer of the Internet of Things, Zhongke Cloud Control has developed APP, WeChat applet, PC web and mobile phone web, etc., customer desktop programs and other access applications to meet the various needs of users. The detailed system structure diagram is shown below:
Four system function description:
1. Temperature and humidity alarm
Through the setting of suitable environmental temperature and humidity and the upload of real-time information from the RFID temperature sensor tag, the two are compared in real time, and a warning message is issued to the manager if it is not suitable.
2. Inspection of management personnel
Managers can view the uploaded information of the RFID temperature and humidity sensor obtained by the system through the cloud service platform, and then can detect in real time.
3. Storage of dynamic information of item environment
The data uploaded by the RFID temperature and humidity sensor in real time forms a visual historical change in the system, which is displayed with clear and concise graphics and data, and you can view the changes in environmental temperature and humidity during a certain period of time, which is conducive to the prediction and work of the detection convenient.
4. Cold chain logistics
Based on the integration of RFID radio frequency identification technology, sensor technology, wireless communication technology, GPS positioning and cloud database, it can realize the monitoring of cold chain logistics, efficiently work on the entire operation chain and ensure the avoidance of problems. (That is, the items on the move are also tested)
Five system characteristics
Data reliability: RFID can set the storage interval by itself. Continuously store temperature and humidity information, and upload data to the enterprise and cloud platform at the same time. All data is stored in one direction and cannot be changed, which facilitates information traceability and facilitates the definition of responsibilities.
Large storage capacity: RFID tag data storage capacity is large, low consumption, long life, and reusable.
Long distance: R11 reader, its visual reading and writing distance is up to 100 meters, R63 wireless sensor, its visual receiving distance is 3km, the connection distance is up to 7-10km, and the network cost is low.
Arbitrary arrangement of measuring points: The measuring points can be arranged according to the test object, and the operation is simple. It can monitor the temperature and humidity of different locations in the space, and can also detect the temperature and humidity data of different packaging units.
Real-time data upload: real-time upload of inspection data to the monitoring center or relevant person in charge, providing a reliable basis for enterprise quality management and production scheduling
ID binding: RFID unique ID feature; it can be bound with cold chain equipment and goods, and through identification, it can realize the warehouse automation management of the rectification of the logistics process.
