RFID-based temperature detection system and method

Abstract

The invention discloses an RFID-based temperature detection system and method, and the system comprises a sensing monitoring module which is used for detecting the state information of a to-be-detected device; the data collection module is connected with the sensing monitoring module and is used for collecting monitoring data; the receiving module is wirelessly connected with the data collection module and is used for receiving the monitoring result to judge the equipment state; the antenna can be used for transmitting radio frequency waves, the radio frequency waves activate the sensor to work and transmit a temperature measurement command, digital protocol communication and digital transmission are used in the whole process, CRC check codes are used for error correction, and communication is stable and reliable; through cable head phase current comparison, loop load rate comparison and environment temperature comparison, a loop with abnormal temperature rise can be quickly screened in advance, passive power failure events caused by fault expansion are greatly reduced, and the temperature rise condition of key parts of the switch cabinet is accurately and timely monitored; a wireless passive design is adopted, the sensor does not need a battery or induction electricity taking, and the temperature change of the contact of the switch cabinet is monitored on line in an all-weather and real-time manner.

Description

technical field [0001] The present invention relates to the field of power equipment monitoring, in particular to an RFID-based temperature detection system and method. Background technique [0002] The cable joint is also called the cable head. After the cable is laid, in order to make it a continuous line, each segment of the line must be connected as a whole, and these connection points are called cable joints. The cable joint is used to lock and fix the incoming and outgoing lines, which play the role of waterproof, dustproof and anti-vibration, and the outer skin of the cable joint is an insulating layer to avoid leakage and ensure the safe and stable operation of the power line. The insulating layer of the cable head will gradually age with the use of time, which will reduce its insulation performance, causing hidden dangers such as leakage, thermal expansion and even explosion at the cable head. In particular, the cable head buried in the cable trench has a long serv...
