一种换能器保护系统及保护方法

By designing a transducer protection system that includes a signal source, a protection module, and a power amplifier, the system predicts and adjusts the signal to prevent the power amplifier from driving the signal too large. This solves the problem that traditional protection modules cannot effectively protect the transducer, and achieves reliable operation and extended lifespan of the transducer.

AI Technical Summary

Technical Problem

In the existing technology, when a power amplifier is used to drive a composite transducer that integrates multiple transducers at the same time, the traditional transducer protection module cannot work properly and cannot effectively protect the transducer.

Method used

Design a transducer protection system, including a signal source, a protection module, a power amplifier, and a transducer module. The protection module predicts displacement and temperature based on the signal, the amplification factor of the power amplifier, and the transducer parameters, generates the prediction results, compares them with preset values, and adjusts the signal to form a drive signal. This avoids excessive drive signal power generated by the power amplifier and ensures that the transducer operates within the design values.

Benefits of technology

It effectively protects the transducer, prevents overwork, and improves the transducer's conversion power and service life.
