Handheld building material recognition device based on RFID technology

Abstract

The invention relates to the technical field of RFID identification terminals, and discloses a handheld building material recognition device based on RFID technology, which comprises an RFID identification terminal body, and is characterized in that the outer wall of the RFID identification terminal body is fixedly connected with a cylinder, the inner wall of the cylinder is movably connected witha screw rod, the rod wall of the screw rod is in threaded connection with a fixing nut, and the side wall of the screw rod is fixedly connected with a fixing cylinder; a through hole is formed in thelower surface of the fixing cylinder, a threaded cylinder is movably connected to the hole wall of the through hole, a threaded rod is in threaded connection to the inner wall of the threaded cylinder, and a rolling bearing fixedly sleeves the rod wall of the threaded rod. The handheld building material recognition device has a length adjusting function, the building material RFID tag recognitionefficiency and convenience of the handheld building material recognition device are improved, meanwhile, the labor intensity of workers can be reduced, the working comfort of the workers is improved,and the working efficiency of the workers is improved. Protection capability of the handheld building material identification device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of RFID identification terminals, in particular to a handheld construction material identification device based on RFID technology. Background technique [0002] RFID is also called radio frequency identification. Its principle is non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID is widely used. Typical applications include animal chips, access control, parking lot control, and material management. etc., and the RFID handheld terminal is also called PDA, which has the function of reading and writing RFID, and can read the RFID tag. It is a set of hardware with specific functions, such as identifying the RFID tag on the building material through the RFID handheld terminal to read the material and material information of the material, so as to ensure the quality of the building material. [0003] At present, when the hand-held building materia...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when identifying the RFID tags of building materials, the staff needs to bend over or climb up frequently, which makes the identification process too cumbersome and inconvenient, time-consuming and labor-intensive, and thus affects the identification of building materials by the hand-held building material identification device. The efficiency and convenience of RFID tags, while increasing the labor intensity of staff, and a handheld construction material identification device based on RFID technology is proposed
