RFID ruler scale device with communication microchannel and construction method thereof

Abstract

The invention discloses an RFID scaleplate scale device with a communication micro passage and a building method of the RFID scaleplate scale device with the communication micro passage. The RFID scaleplate scale device with the communication micro passage comprises two or more micro passage assemblies, a channel converging rail, a scaleplate pointer, a shielding assembly and a scaleplate. Each micro passage assembly further comprises a micro channel outlet embedded into a through hole of the channel converging rail, the scaleplate pointer is arranged on the shielding assembly, one end of the scaleplate pointer is directed at the scaleplate, and the interval between every two adjacent micro passage assemblies corresponds to the scales on the scaleplate. The shielding assembly can move on the channel converging rail along with the scaleplate pointer in two directions, when the shielding assembly moves to the position above any one micro channel outlet along with the scaleplate pointer, the shielding assembly connects or disconnects the communication between an RFID electronic tag corresponding to the micro channel outlet and an external RFID system, and therefore changes of an external measurement angle or linear displacement are obtained. The RFID scaleplate scale device with the communication micro passage and the building method of the RFID scaleplate scale device with the communication micro passage have the advantages of being simple in measurement, convenient to built and capable of being identified in a non-touch mode and achieving real-time detection, and can be widely applied to the field of engineering measurement.

Description

technical field [0001] The invention relates to a scale calibration device, more specifically, to an RFID scale scale device with a communication microchannel and a construction method thereof. Background technique [0002] RFID (Radio Frequency Identification) technology is a wireless communication technology, also known as electronic tag technology or radio frequency identification technology. Establish mechanical or optical contact. The specific process is: after the electronic tag Tag enters the antenna magnetic field, it receives the radio frequency signal sent by the reader, and sends out the product information (Passive Tag, passive tag or passive tag) stored in the chip by virtue of the energy obtained by the induced current, or by The tag actively sends a signal of a certain frequency (ActiveTag, active tag or active tag), the reader reads and decodes the information, and sends it to the central information system for relevant data processing, which has the outstan...
