Low power consumption wireless active temperature label

Abstract

The invention relates to a low power consumption wireless active temperature label which comprises a temperature sensor, a radio frequency electronic module, a processor module, a power module and an antenna, wherein the temperature sensor is used for measuring the temperature value of a to-be-detected object; the processor module is used for controlling the work of all the other modules, acquiring the temperature value of the to-be-detected object measured by the temperature sensor, receiving user commands and outputting prompting message, and is in an inoperative state when not used; the radio frequency electronic module is used for storing temperature value information and sending temperature value information to an external card reader; and the power module is used for providing working voltage for the low power consumption wireless active temperature label. The low power consumption wireless active temperature label provided by the invention has a temperature measuring function as well as the functions of an electronic tag, all the temperature collection period, data sending period and sending frequency can be adjusted automatically, battery capacity check can be performed too, and the low power consumption wireless active temperature label has the characteristics of initiative submission, passive inquiry, low power consumption and the like.

Description

technical field [0001] The invention relates to the fields of temperature measurement and radio frequency, in particular to a low-power wireless active temperature label. Background technique [0002] For temperature monitoring during cold chain transportation, the temperature recorder is traditionally used to measure and record the temperature of the entire compartment, that is, a temperature recorder is placed in each compartment to measure and record the temperature during transportation. After the goods arrive at the transportation destination, connect the temperature recorder to the computer and import the data into the computer, and then perform data statistics and analysis. Traditional temperature recorders have disadvantages such as high price, single monitoring object, lack of digital identification, and need for wired connection, etc., which cannot meet the requirements for temperature monitoring of goods in the compartment during cold chain transportation.
