RFID sensor for water leakage detection of water pipe

Abstract

The invention discloses an RFID sensor for water pipe water leakage detection, which comprises a first radio frequency transceiver, a second radio frequency transceiver, a coding module and a sensing module, and is characterized in that when the RFID sensor is used for water pipe water leakage detection, the sensing module detects the current state of a detected water pipe in real time and generates sensing information representing the current state of the water pipe; the first radio frequency transceiver receives radio frequency signals and transmits the radio frequency signals to the coding module, the coding module loads coding information in the radio frequency signals and then sends the coding information to the sensing module, and the sensing module loads sensing information in the radio frequency signals and then sends the sensing information to the second radio frequency transceiver. The second radio frequency transceiver transmits a radio frequency signal with coding information and sensing information to a free space; the system has the advantages that the system is realized by adopting the chipless RFID tag, can replace a traditional semiconductor sensor, is arranged below the water pipe as a sensing node to detect the state of the water pipe, is low in cost under large-scale arrangement, does not need a complex connecting line with a terminal processing system, and has a great application prospect.

Description

technical field [0001] The invention relates to an RFID sensor, in particular to an RFID sensor for detecting water leakage in a water pipe. Background technique [0002] In modern buildings, plumbing arrangement is an essential part. However, after long-term use, water pipes are prone to aging damage or loose joints, resulting in water leakage, affecting the experience of family homes, building life, and factory and laboratory safety. The traditional water pipe leakage detection scheme usually adopts direct detection and positioning technology. The water leakage detection is carried out by placing humidity or other gas-sensitive sensors around the pipes. The sensors can sensitively sense water leakage around the pipes and generate corresponding signals to send to the back-end terminal. The processing system, the terminal processing system triggers the alarm. However, the sensors used in the traditional direct detection and positioning technology are usually semiconductor ...
