Active RFID temperature acquisition device and temperature acquisition method thereof

Abstract

The invention provides an active RFID temperature acquisition device and a temperature acquisition method thereof, wherein the temperature acquisition device includes a main control module, a power management module, a temperature acquisition module and a power supply module; wherein the power supply module is connected to the power management module and the main control module respectively The modules are connected, and the current output by the power supply module supplies power to the power management module and the main control module; the main control module includes a controller and a memory, wherein the controller is connected to the memory and the power management module respectively; the temperature acquisition module is respectively connected to the controller and the power supply The management module is connected, wherein, the controller controls the power management module to output the constant current source reference voltage and the temperature acquisition power supply voltage required by the temperature acquisition module, so that the temperature acquisition module collects the temperature, and the controller stores the temperature collected by the temperature acquisition module in the in memory. The invention can automatically read the product temperature data in the refrigerated vehicle, so as to achieve the purpose of monitoring and tracing the product temperature and ensuring product quality and safety.

Description

technical field [0001] The invention relates to the technical fields of temperature collection and active RFID, and more specifically, to an active RFID temperature collection device and a temperature collection method thereof. Background technique [0002] RFID (Radio Frequency Identification, radio frequency identification) and temperature acquisition are two highly independent products. Because RFID technology has the characteristics of non-contact identification, high efficiency and convenience, it is widely used in logistics, retail consumer goods, medical management, In industries such as transportation, national defense and military industry, especially the unique identification characteristics of RFID to objects, it can not only be used in some special areas where wiring and power supply are difficult or people cannot reach, but also can identify items in the target area. Positioning and distinction to achieve the purpose of tracing the item information. [0003] In...

AI Technical Summary

Problems solved by technology

[0004] In the existing cold chain transportation process, because it does not effectively combine RFID technology with temperature collection, the temperature of the transported products cannot be monitored, collected and recorded during the transportation process, nor can the information of the transported products Traceability, so the quality and safety of products in the entire cold chain transportation link cannot be guaranteed
