Method and system for monitoring working temperature of spherical transducer

Abstract

The invention provides a method and system for monitoring the working temperature of a spherical transducer. The method comprises the steps: ensuring that the temperature of spherical piezoelectric ceramic and the temperature of a thermocouple are consistent; bonding the hot terminal of the thermocouple with a temperature measuring point of the spherical piezoelectric ceramic; fixing the joint byusing a small amount of conductive material; using a post-processing module for measurement, and reducing the temperature to the room temperature; when the adhesive layer is smeared, preprocessing thejoint firstly; when the spherical piezoelectric ceramic is encapsulated, smearing a small amount of encapsulating material at the joint; using a post-processing module for measuring the temperature change condition of the spherical transducer; and carrying out temperature related test on the transducer to realize real-time monitoring of the temperature of the transducer. According to the invention, the K-type thermocouple is selected as a temperature sensor, and an effective transducer temperature monitoring system is established through a proper scheme in combination with the characteristicsof the spherical transducer, so that the measurement method is simple and convenient and has relatively high engineering applicability.

Description

technical field [0001] The invention relates to the field of transducer working state monitoring, in particular to a method and system for monitoring the working temperature of a spherical transducer. Background technique [0002] In the development of modern underwater acoustics, underwater acoustic equipment shows a trend towards high power, high stability, and long-term use. In underwater acoustic equipment, the importance of the transducer has become increasingly prominent, and it has become the focus of underwater acoustic equipment research. When the transducer is used to emit sound wave signals, due to the energy loss of the transducer itself, all the electrical energy cannot be converted into sound energy, and most of the lost electrical energy is converted into heat energy. At the same time, since the radiating surface of the transducer is often covered by a watertight layer, and the thermal conductivity of the watertight layer is generally poor, the heat energy ca...
