Abstract

The invention discloses an RFID (radio frequency identification) passive sensing device for measuring the temperature of the cable head conductor of a ring main cabinet. The device comprises an RFID passive sensor, an RFID temperature reader antenna and an RFID temperature reader; the RFID passive sensor comprises a passive temperature measuring mechanism and an electromagnetic shielding mechanism, wherein the passive temperature measuring mechanism includes a first housing, an RFID tag, a temperature sensor, and a temperature measuring contact; the RFID temperature reader includes a second housing, an integrated sealing cover, a wireless transmitting / receiving module, an external communication module, a controller, a storage battery and a display screen; and the RFID temperature reader antenna and the controller are connected with each other. The RFID (radio frequency identification) passive sensing device for measuring the temperature of the cable head conductor of the ring main cabinet of the invention has the advantages of reasonable structure, simple structure, convenient use, strong anti-interference capacity, small size, high stability, convenient installation, long readingdistance, high safety, high reliability and the like. With the device of the invention adopted, the problem of potential safety hazards during the measurement of the temperature of the cable head conductors of ring network cabinets in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of temperature measuring equipment for cable head conductors of ring network cabinets, in particular to an RFID passive sensing device for measuring the temperature of cable head conductors of ring network cabinets. Background technique [0002] In recent years, with the rapid development of RFID technology, the application of radio frequency identification tags has been greatly expanded. From the previous only transmission of data stored in the tag to represent its identity, it has expanded to more and more application fields. For example, when transmitting the data representing the identity, the ambient temperature data can be transmitted together, so that the reader or server can obtain the ambient temperature where the tag is located. [0003] In the prior art, no matter whether active or passive RFID technology is used in the combination of video recognition and temperature sensing, the temperature measurement f...
