Problems solved by technology

[0006] Disadvantages of this technology: 1. The special cable proposed in the above scheme includes a temperature measurement function, but because of its complex structure, the implementation cost is relatively high
[0007] 2. It is impossible to measure some temperature measurement points on site
[0008] 3. When there are many cables, there is no hair to distinguish
[0011] 1. The temperature measuri...

Embodiment 1

[0034] It includes a passive RFID temperature measurement label 1 arranged on the cable; the passive RFID temperature measurement label 1 is installed outside the skin of the existing cable 2, and the passive RFID temperature measurement label is attached with an adhesive layer that can be adhered, The passive RFID temperature measurement label is fixed and pasted to the outside of the cable skin through the adhesive layer at the bottom and is in close contact with the outside of the cable skin;

[0035] The passive RFID temperature measurement label includes a base 11, the adhesive layer is arranged on the bottom of the base 11, and an RFID chip 12 with an automatic tuning circuit is installed on the upper end of the base;

[0036] An RFID antenna 13 is provided at both ends of the RFID chip. The RFID antenna 13 is in a spiral shape, and the bottom of the RFID antenna 13 is attached to the upper surface of the substrate 11 .

[0037] Wherein, the material of the RFID antenna ...

Embodiment 2

[0044] Such as image 3 As shown, the entire passive RFID temperature measurement label is installed in the protective layer of the cable. This method must be installed when the cable is made. After being installed in the cable protective layer in this way, the advantage is that it is more protective. Well, it is not easy to fall off and has a longer service life, but it is more troublesome to replace the top, so you can choose an installation method according to your needs in actual use.

[0045] Beneficial effects of the present invention: the present invention can mount a passive RFID temperature measuring label at any position of the cable, since the temperature measuring device is a label, and the volume of the label is not large, so the operation can be completed in a narrow space; Installing a passive temperature measurement label at any position of the cable can realize the temperature measurement and marking of the cable. The installation is simple and the installation ...

Abstract

The present invention discloses a cable temperature measurement device based on an RFID technology. The cable temperature measurement device based on the RFID technology comprises a passive RFID temperature measurement label arranged on a cable, the passive RFID temperature measurement label is fixedly adhered on the skin exterior of the cable via a bottom adhering layer, is contacted with the skin exterior of the cable tightly, and comprises a substrate, and an RFID chip with an automatic tuning circuit is installed on the upper end face of the substrate. According to the present invention, the passive RFID temperature measurement label can be pasted at any position of the cable, the label is small in size and is not influenced by the diameter of the cable, and the label can be bent along with the cable and can carry out the cable identification and the remote temperature measurement. The label identification has the characteristics of being strong in penetrability and long identification distance, being able to count the large-batch labels simultaneously, the problems that the conventional cable temperature measurement device can not be counted due to the enclosed wirings, the one-by-one counting efficiency and the accuracy are low, etc., are solved, and the cable temperature measurement device based on the RFID technology has the characteristics of being low in maintenance cost and high in accuracy and benefit, being convenient to install, etc.

Description

technical field [0001] The invention relates to a cable temperature measuring device based on RFID technology. Background technique [0002] Cables can be seen everywhere in daily production and life. Power plants, factories, and laboratories usually lay a large number of cables in cable trenches to facilitate wiring, maintenance, and aesthetics. With the increase of people's dependence on electricity, there are more and more cables in the cable trench, and the cable trench is getting longer and longer. The probability of fire accidents also increases accordingly. Once a cable fire occurs, a large area of ​​the cable will be burned, and production cannot be resumed in a short time, resulting in heavy economic losses. Therefore, the safety protection of cables has become a problem that cannot be ignored. [0003] The main reason for the fire in the cable trench is caused by the poor quality of the intermediate joints of the cables, or the crimping is not tight, or the weld...
