Data acquisition device of RFID (Radio Frequency Identification Device) electronic tag for monitoring environmental data in cold chain logistics

Abstract

The invention relates to a data acquisition device of an RFID (Radio Frequency Identification Device) electronic tag for monitoring environmental data in cold chain logistics, which is characterized by comprising an RFID data receiving module, an environmental data receiving module, a storage module, an antenna, an LED display module, a central processor and a power supply module, wherein the RFID data receiving module, the environmental data receiving module, the storage module, the antenna and the LED display module are all connected with the central processor and the power supply module, and the environmental data receiving module comprises a temperature data receiving unit, a humidity data receiving unit, a pressure data receiving unit and a photosensitive data receiving unit. In the invention, by matching with RFID temperature / humidity / pressure / photosensitive tags, data acquisition on the temperature, humidity, photosensitivity, pressure and other data in the production, transportation and sales processes of the cold chain industry and GPS (Global Position System) position information can be reliably realized in real time.

Description

technical field [0001] The invention relates to an RFID collection device, in particular to a data collection device for cold chain logistics environment data monitoring RFID electronic tags. Background technique [0002] The so-called cold chain logistics generally refers to a systematic project in which temperature-sensitive products are always kept in a specified low-temperature environment in all links of production, storage, transportation, sales, and consumption to ensure the quality of items and reduce logistics losses. It is established with the development of logistics technology and refrigeration technology, and is a low-temperature logistics process based on refrigeration technology and refrigeration technology. The cold chain consists of four aspects: frozen processing, frozen storage, refrigerated transportation and distribution, and frozen sales [0003] The general RFID tag only sends out the unique ID number. However, the purpose of cold chain logistics is t...

Problems solved by technology

[0003] The general RFID tag only sends out the unique ID number. However, the purpose of cold chain logistics is to ensure the quality of refrigerated and frozen items. In cold chain logistics transportation, we not only need to know the unique ID number of the tag, but also need to know it in real time Understand the data and changes of temperature, humidity, photosensitive and pressure in the surrounding environment of the tag. However, the current RFID electronic tags cannot meet the above requirements, and there is no dedicated RFID temperature / humidity / pressure / photosensitive for cold chain logistics.
