Problems solved by technology

At the same time, due to the long length of the cable, when the cable is set in the trench, it is difficult to monitor the temperature of the cable. In the traditional active sensor solution, the sensor needs a built-in battery, and the service life is limited. The battery often needs to be replaced. The passive wireless temperature monitoring system of radio frequency identification (RFID) technology is a kind of ideal solution, but prior art does not disclose the technology based on the passive wireless temperature monitoring of radio frequency identification technology

Abstract

The invention discloses a cable temperature monitoring system based on intelligent Internet of Things. The cable temperature monitoring system is characterized in that a temperature collector corresponds to a group of RFID (radio frequency identification) temperature tags; each RFID temperature tag in each group of RFID temperature tags is respectively arranged at a monitoring point of a to-be-monitored cable; a through hole is formed in the middle part of a flexible insulation substrate; a heat conduction metal block is embedded into each through hole; a temperature measuring chip is in contact with each heat conduction metal block, and is connected with a super-high frequency RFID chip; an antenna is connected with each super-high frequency RFID chip, and is positioned on each flexible insulation substrate; the antenna in each RFID temperature tag in each group of RFID temperature tags is connected with the corresponding temperature collector, and the output end of each temperature collector is connected with a gathering controller. The cable temperature monitoring system is capable of realizing the passive and wireless temperature monitoring on the cable in a channel.

Description
