Embodiment

[0024] In this embodiment, the battery module, the Flash memory module, the RFID module, the acceleration / geomagnetic field sensor module, the real-time clock module, and the microprocessor module are integrated into a card with the same length and width as a business card and a thickness of 4mm. The acceleration / geomagnetic field sensor module detects the parameters of gravitational acceleration and geomagnetism in its internal three-dimensional coordinate system; the microprocessor obtains the inclination direction of the object attached to the tag relative to the ground surface through coordinate transformation according to the detected gravitational acceleration and geomagnetic three-dimensional parameters And degree, compared with the set value, if there is an abnormal state, the microprocessor will read the time of the real-time clock module as a timestamp and save it in the Flash memory chip together with the tilt data; when the RFID module receives external read informat...

Abstract

The invention discloses an active electronic tag capable of detecting and recording an angle of inclination. The active electronic tag comprises an RFID module, a microprocessor and a storage module, wherein the microprocessor and the storage module are sequentially connected. The RFID module is connected with the microprocessor and the storage module, and two-way data transmission is conducted. The microprocessor is simultaneously connected with an acceleration and geomagnetic sensor and a clock module. The acceleration and geomagnetic sensor detects earth gravity acceleration and a geomagnetic field, the microprocessor analyzes and processes data, a result is acquired and stored in a storage, and the RFID module conducts data interaction with the external environment. The storage module is a Flash storage module. The active electronic tag comprises a battery module, and the battery module supplies power to the microprocessor, the storage module, the acceleration and geomagnetic sensor and the clock module. The battery module, the Flash storage module, the microprocessor, the RFID module, the acceleration and geomagnetic sensor and the clock module are integrated in a card.

Description

technical field [0001] The invention belongs to the technical field of electronic information, in particular to an active electronic tag capable of detecting and recording tilt angles. Background technique [0002] RFID technology, also known as radio frequency identification technology, can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. Currently, RFID technology is widely used in libraries, access control systems, Food safety traceability and other occasions are widely used. [0003] MEMS is a micro-electro-mechanical system, which is a multidisciplinary frontier field developed in the field of microelectronics technology. MEMS sensor is a new type of sensor manufactured by microelectronics and micromachining technology. Compared with traditional sensors, it has the characteristics of small size, light weight, low cost, low power con...
