System and method capable of sensing temperature

Abstract

The invention provides a system and method capable of sensing temperature. The method comprises the steps that a temperature changing layer comprises a first reversible thermochromic layer, a first irreversible thermochromic layer, a second reversible thermochromic layer and a second irreversible thermochromic layer; when the temperature of the temperature changing layer reaches or exceeds a preset temperature, the four color changing layers change colors to remind a user; when the temperature of the temperature changing layer reaches or exceeds the second temperature and the fourth temperature once, the first irreversible thermochromic layer and the second irreversible thermochromic layer change colors to remind a user; the temperature sensing wire is connected to the temperature controller to monitor the temperature of the cable in real time, and when the temperature of the cable exceeds a preset safety range, the temperature controller reminds a user. According to the system designed by the invention, the problem that the temperature rise of the cable cannot be detected is solved, and the temperature rise of the cable can be found after a short time. The used cables are easy tomanufacture in batches in industry, and the used temperature controller can use the existing equipment, so that the cost is reduced.

Description

technical field [0001] The patent of the present invention belongs to the field of wire rod protection, and in particular relates to a system and method capable of sensing temperature. Background technique [0002] There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. Cable safety is critical. [0003] Normally, the temperature of the cable will rise slightly. However, when the electric appliance is overloaded with a safe current or there is a short circuit, the temperature of the cable will increase or even burn out. And it may not be noticeable until it burns out. The short-term temperature rise of the cable may affect the service life of the cable, and it is impossible to find that the temperature of the cable has risen afterwards. Contents of the invention [0004] In view of the above problems, the present invention designs...

AI Technical Summary

Problems solved by technology

However, when the electric appliance is overloaded with a safe current or there is a short circuit, the temperature of the cable will rise or even burn out.

and may not be noticed until burned

The short-term temperature rise of the cable may affect the service life of the cable, and it is impossible to find that the cable has heated up afterwards.
