Wireless temperature measurement sensor based on voltage induction power acquisition

Abstract

The invention discloses a wireless temperature measurement sensor based on voltage induction power acquisition.The sensor comprises a fixing system, a power acquisition system, a power module, a temperature sensor, a controller and a communication module, wherein the fixing system comprises a U-shaped clip, a screw and a shell.In use, a high-voltage bus is clamped in the U-shaped clip.The power acquisition system comprises a first pole plate and a second pole plate which are arranged in the shell, and a capacitor is formed by the first pole plate and the second pole plate.The first pole plate and the second pole plate are connected with a contact A on a circuit board through conductors respectively, and the screw is connected with a contact B on the circuit board through a conductor.The contact A and the contact B input alternating current into the power module, and the power module converts the input alternating current into direct current to be output and supplies power to the temperature sensor, the controller and the communication module.The controller is used for managing the temperature sensor and the communication module.The temperature sensor is arranged in the shell, and a measurement result is sent to the communication module.The communication module sends the measurement result out.

Description

technical field [0001] The invention relates to a wireless temperature measuring sensor. Background technique [0002] High-voltage power transmission is more and more used in real life, so it is even more important to monitor the real-time status of power transmission lines. Traditional wire monitoring methods are often affected by geographical location and surrounding environment in real life, and cannot perform real-time and accurate temperature monitoring and early warning, resulting in immeasurable losses during power transmission. Real-time monitoring based on this high-voltage line has been introduced into the topic of research institutions more and more. With the continuous advancement of temperature measurement technology, especially the emergence of high-precision and long-life sensors, temperature measurement has become easier. Once the temperature of the high-voltage transmission line is too high and the conductor is fused, this will cause a power outage in the...
