Intelligent temperature and pressure sensing tag

Abstract

The invention provides an intelligent temperature and pressure sensing tag and belongs to the field of sensors, aiming at solving the problems that existing tags having sensing functions are large in size, have large power consumption, and are far from 'tag' virtually. The sensing tag comprises an outer casing. An outer periphery of an upper surface of a base plate inside the outer casing is encircled with an antenna. An energy storage module and a wireless communication module are installed side by side on a lower surface of an inner part of an area, surrounded by the antenna, of the base plate; a D single chip is installed on an upper surface of an inner part of an area, surrounded by the antenna, of the base plate, wherein the D single chip is packaged by a signal processing control module, a pressure sensing layer, and a temperature sensing layer through a wafer level packaging technology. An upper surface of the signal processing control module is provided with the annulus temperature sensing layer. An upper surface of the temperature sensing layer is provided with a pressure sensing layer. The inner part of an annulus area of the temperature sensing layer is provided with a connecting layer. Two input ends of the energy storage module are connected to two ends of the antenna; an output end of the energy storage module is connected to an input end of a power supply of the signal processing control module.

Description

technical field [0001] The invention relates to intelligent measurement technology and belongs to the field of sensors. Background technique [0002] RFID technology has been widely used in information acquisition, especially all kinds of smart electronic tags, most of which are realized by using radio frequency RFID technology. The main form is to store an electronic code inside, and some also have a certain storage space. The vast majority of products do not have sensing and measuring functions, but are only records of equipment IDs or codes. Other important environmental parameter data cannot be obtained during the process. Since most smart labels are used in warehousing and freight, logistics management, personnel management and other fields, their lack of Compared with the original barcode scanning function, the sensing function makes its labeling function not substantially improved in terms of advanced nature. [0003] At present, there are also some tags with sensing...
