About High Temperature RFID Tag

With the deepening and increasing of application scenarios, RFID tags have undergone new iterative changes in process technology and product form. In general, the development of UHF RFID technology mainly has three directions: positioning, encryption and sensor integration. In this regard, it is no exaggeration to say that the new sensor tag redefines the High temperature RFID tag.

The new RFID sensor tag integrates the sensing capability into the original functional characteristics of the tag, which greatly improves the function and application flexibility of the tag. It can be clearly felt that it has expanded more space in RFID application. At present, passive RFID sensor tags are used in warehousing and logistics, medicine, agriculture, animal husbandry, automobile, electric power, transportation and other scenarios.

Passive RFID high temperature tag can identify the accurate time of temperature change, collect temperature data in real time, and transmit the data to the reader for recording. It is dedicated to identifying and locating objects, and is widely used in mechanical temperature monitoring and cold chain transportation. The following will explain in detail the application of RFID high temperature electronic tags in mechanical control and cold chain logistics.

The subway connecting Hong Kong and Shenzhen carries hundreds of thousands or even millions of passengers every day. The service time of the train is as long as 18 hours every day. Such a high carrying workload makes the maintenance and inspection work a tedious work. In the past, it was difficult for the MTR to immediately check the health of its vehicles. After high temperature or long-term operation, the power system and power supply system are often abnormal during train operation, which causes the train to stay on the road for many times, and the railway traffic condition is delayed for several hours, thus causing inconvenience in peak hours. Even when the train returns to the factory, the engineers are unable to test and inspect hundreds of important equipment of each train one by one, so this has become a major problem in Metro machinery management.

The Passive RFID high temperature electronic tag can record and store the temperature point, clock, tag battery status and other information. The storage space is up to 1000 pieces of information. When the train passes through the station, the temperature information can be completely transmitted within 20 seconds. The control center can observe the safety status of all devices, and truly realize real-time reporting every minute; The RFID temperature tag has advanced power saving mode and open setting function. The user can independently set the sending interval, receiving interval, recording start and recording interval of the temperature tag. When the train returns to the terminal in the evening, it enters the stop recording mode.

The working principle of the OPRFID technologies’ passive RFID tag high-speed lamination machine is to bond the antenna and the inlay first, and then perform composite die cutting on the blank tag and the bonded inlay through the die cutting station. If it needs to be made into a self-adhesive type, it needs to add adhesive and backing paper. If it is made into a label type, it can directly process the data of the tag, and the finished passive RFID tag can be directly applied in the terminal.

Next, let’s talk about RFID cold chain logistics. From unloading, packaging, storage to transportation, there must be real-time visual temperature control to maintain the original value. In the cold chain logistics, the temperature of the environment where the materials are located is recorded completely, which plays a positive role in the preservation of the materials and the investigation of the causes of the problems. The High temperature RFID tag(more info) can measure and record the ambient temperature of the material while identifying the material. It can judge whether the ambient temperature of the material exceeds the allowable range during storage and transportation in real time, and realize the traceability of the whole quality process.

The temperature box is the most common application environment in the cold chain and the hot chain and the largest number of single products. The probe of the RFID temperature tag is put into the temperature box through the hole to monitor the temperature in the box in real time. Suitable for hot chain catering distribution, seafood food, blood package distribution, etc. After long-term laboratory validation, aging test and rich experience in project use, our temperature label is suitable for high-temperature disinfection at 100 ℃. The installation of the system is simple. The temperature data collection can be completed only by placing the label probe into the temperature box and the label shell close to the outside of the temperature box.

The RFID temperature tag is directly placed in the cold car compartment to monitor the temperature of the transported goods. Put the reader / writer in the cab, introduce the equipment into the cold compartment, and put the temperature label directly into the cold compartment to find a suitable position for fixation. The temperature change in the cold car is transmitted to the temperature control center in real time through the reader / writer. The control center is responsible for the information exchange with the intelligent vehicle terminal, the classification, recording and forwarding of various short messages, the network interconnection with other relevant functional departments, and the flow of business information between these departments; At the same time, monitor and manage the whole network. It is suitable for blood, vaccine, fresh food, ice cream truck, frozen meat, distribution, etc.
