Embodiment Construction

[0026] Such as figure 1 As shown, a cold chain RFID temperature electronic tag based on NFC, including:

[0027] Radio frequency unit: It is a radio frequency chip integrated with the ISO / IEC 14443 standard protocol controller. It works in passive mode. When the NFC read-write device initiates a command operation, it writes configuration information to the storage unit according to the command, or writes configuration information from the storage unit. Read the corresponding data and send it to the NFC device, and all its command operations conform to the ISO / IEC 14443 protocol standard;

[0028] Real-time clock unit: The RTC unit with its own crystal oscillator runs the real-time clock of UTC standard to record the current time. When performing temperature collection, it can calibrate the current real-time time at the moment of temperature collection;

[0029] Temperature acquisition unit: This unit is a digital temperature sensor, controlled by the control unit, which colle...

Abstract

The invention discloses a cold chain RFID (Radio Frequency Identification Devices) temperature electronic label based on NFC (Near Field Communication). The cold chain RFID temperature electronic label comprises a radio frequency unit, a temperature collecting unit, a data storage unit, a real-time clock unit and a control unit. The temperature collecting unit and the real-time clock unit are respectively connected with the control unit; the control unit and the data storage unit are connected with each other and can be operated in double ways; and the data storage unit is simultaneously connected with the radio frequency unit. The data storage unit is supplied with power by a battery while being read and written by the control unit. The electronic label disclosed by the invention can be used for recording the temperature of a cold chain product by using a periodic or temperature overranging method, writing the temperature into a label memory, reading the temperature record in the later stage, determining the quality of the cold chain product and tracing the product problem link. The temperature can be very conveniently read by portable equipment, such as a mobile phone supporting NFC and the like; therefore, the temperature information of each link and period of the cold chain are clear at a glance and the purpose of tracing the cold chain product is simply achieved in time.

Description

technical field [0001] The present invention relates to the fields of radio frequency communication application and cold chain temperature monitoring, and specifically provides a radio frequency identification temperature recording electronic tag based on NFC near-field communication technology. The electronic tag can be easily read by portable devices such as mobile phones supporting NFC. The temperature information of each link and cycle of the chain is clear at a glance, and the traceability of cold chain products can be achieved in a timely and simple manner. technical background [0002] With the continuous improvement of people's living quality and China's accession to the WTO, the circulation of agricultural products and food is facing new challenges. In recent years, incidents such as problematic pork, gutter oil, and melamine milk powder have emerged one after another, and food safety issues have attracted more and more people's attention. The traceability system i...
