Cable temperature measurement device based on RFID technology

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...

AI Technical Summary

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 measuring device of this structure must be inserted from one end of the cable. When the cable is too long, it is difficult to implement;

[0012] 2. The thickness of the cable affects the temperature measurement contact point, which cannot guarantee the effectiveness of temperature measurement;

[0013] 3. It cannot be installed in a narrow space;

[0014] 4. When there are many cables, there is no hair to distinguish
