Cold chain, that is, the refrigeration of refrigerated refrigerated supply chain, normally refers to the supply of logistics from raw materials, producing logistics, storage transportation logistics to trafficking, and is always in the specified low temperature environment in various links. The quality of food, reducing a system engineering for food loss. With the advancement of science and technology, it is based on the development of refrigeration technology. It is based on refrigeration technology. The low temperature logistics process of refrigeration technology is means, and the low temperature logistics transmits transportation through management procedures. Relevant logistics function activities such as warehousing, loading, unloading, packaging, distribution and information, to create value, meet customer and social needs.
According to statistics, food cold chain transportation rates in the United States, Japan and Western Europe reached 80% to 90%, and about 50% of Eastern Europe, and China is only about 10%. It is understood that in 2017, China was discarded by rotten food, and the waste could reach 70 billion yuan, accounting for 20% of the total value of food, and one of the reasons is the lack of cold-chain transportation system. For cold chain transportation, we must master the temperature of its temperature and measure the temperature recorder.
With the development of Internet network technology in recent years, new opportunities have brought new opportunities, using barcodes and collecting equipment of RFID technology to enhance their operational efficiency. The UHF label reader scheme launched by Soping Group Juible Technology is based on RFID technology, which can be used for long distances and quickly read the ONSEMI SPS series by this UHF tag reader. This scenario includes a read head, an antenna and an ONSEMI SPS passive temperature tag. The design of the read head is used by the NXP MK64's industrial grade MCU, adds a UHF (Ultra-high frequency) module to implement data wireless transmission, which is selected from 860-960 MHz. The wireless signal covers the antenna, which can spread a distance of 4 - 5 meters. This readhead scenario supports USB transfer and retains Ethernet, CAN bus and RS232 interface.
The ONSEMI SPS passive label used by the program is a new generation of RFID temperature labels, a label that is closely combined with temperature measurements, and completing the identity identifier through the number identification, and completing the identity of the material The environment is measured and recorded; it is important to require only the current. When entering the validity identification range of the card reader, energy is acquired by the sense of card reader, thereby completing the collection of data exchange and temperature. This temperature tag has a very low consumption current.
Upper machine software operation:
Step 1, perform the Reader setting, select the operating frequency band (865.100-867.900), set the RF power 30dBm, the highest power is set up to 1W.
Step 2, open the serial port.
Step 3, check the Reader Settings Information. You can see that the right box shows the information setting.
Step 4, click the temperature tag bar, set the tag type.
Step 5, set the temperature label to read the frequency. Finally click
"Get Temperature", get the tag temperature information, such as the window.
