摘要

There are many problems when traditional temperature sensing radio frequency identification (RFID) tags are applied to logistics temperature monitoring,such as inconvenient data reading,large power consumption,and low bandwidth.Therefore,a low-dissipation electronic tag is designed in this paper to solve the above problems.The electronic tag and the portable temperature recorder were placed in the same position in the same refrigeration unit,and the temperature of the same space was recorded at the same time,The data measured by the designed electronic tag was used as the measured value,and the data measured by the portable temperature recorder was used as the standard value.The correlation coefficient between the two was calculated to be 0.866 9,the root mean square error (RMSE) was 0.796 7 ℃,and the average relative deviation (ARD) was 16.21％.Therefore,the electronic tag designed in this study can meet the requirements of users for temperature monitoring and recording.The temperature control switch designed in this study can disconnect the power supply to single chip microcomputer (SCM) and other modules when the temperature is in the range of normal threshold,so that the power consumption is further reduced and the cost is reduced.The results of this study laid a foundation for the development of low-cost and easy-to-use temperature monitoring technology in the logistics process.
