The invention provides an electronic tag for monitoring the failure of metal materials based on the RFID technology, which can realize continuous monitoring and early warning of the service status of the metal materials. The working mode of the electronic tag includes: passive mode; in the passive mode, the electronic tag includes: a control unit, an electrical signal detection unit, a radio frequency transceiver unit based on radio frequency identification technology and an environmental sensor; the electrical signal detection The unit is used to obtain the electrical signal collected by the environmental sensor, and determine the level of failure risk of the metal material according to the calculated value of the electrical signal; the control unit is used to obtain the electrical signal through the radio frequency transceiver unit and metal material failure risk levels are transmitted to the external reader; in passive mode, the external reader supplies power to the electronic tag through the radio frequency transceiver unit. The invention relates to the technical field of metal material failure monitoring.
Description
technical field [0001] The invention relates to the technical field of metal material failure monitoring, in particular to an electronic tag for monitoring metal material failure based on RFID technology. Background technique [0002] The failure phenomenon of metal materials is common, especially for metal materials under the cladding, such as: steel pipelines under the insulation layer of petrochemical enterprises and thermal companies, buried steel oil pipelines of oil pipeline companies, buried urban tap water Pipelines, etc., because the degree of failure cannot be visually detected during the service process, once the failure causes perforation, it will cause major economic losses. At present, the detection based on ultrasonic, X-ray or magnetic field technology used in the market is all aimed at the situation that failure perforation or cracking has already occurred, and it cannot realize early warning before failure occurs. Some fields use electrochemical technology...
