Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of acoustic signature detection, specifically to an enhanced fiber optic acoustic signature detection terminal. Background Technology
[0002] During power line inspections, acoustic fingerprinting can be used to detect electrical signals based on ultrasonic waves in the airborne acoustic frequency band, addressing the complex interference from environmental heat sources. This method offers strong resistance to heat source interference, excellent sound source localization capabilities, and intuitive, visualized results. It also provides unique detection effectiveness for terminals that are difficult to detect using infrared detection technology in complex environments.
[0003] For example, Chinese patent CN221922878U discloses an angle adjustment mechanism for a voiceprint detection device of an inspection robot. This component includes a device body, a first bracket, a second bracket, and a push rod motor. The first bracket is installed on the front side of an external robot support, and the second bracket is installed on the bottom of the external robot support. A first hinge seat and a second hinge seat are provided on the back of the device body. The first bracket is hinged to the device body via the first hinge seat. The rear end of the push rod motor is connected to the second bracket, and the front end of the push rod motor is hinged to the device body via the second hinge seat. This invention adjusts the angle of the voiceprint detection device using a push rod motor, resulting in precise angle adjustment and good positioning stability. It avoids the loosening of fit and poor positioning stability caused by excessive adjustments in existing hinged rotational adjustments. However, in this solution, the fiber optic sensor is external, making it susceptible to damage even when not in use. Therefore, we propose an enhanced-sensitivity fiber optic voiceprint detection terminal. Utility Model Content

A signal processing module amplifies, filters, and denoises the captured signals to ensure signal quality suitable for acoustic signature analysis. A movable block allows operators to move the fiber optic sensor module out of the mounting tube for acoustic sampling. After use, the block returns to the mounting tube, protecting the sensor module. Furthermore, a motor, activated by the operator, drives a lead screw, which in turn moves the movable block vertically, further enhancing protection of the sensor module.
[0020] By incorporating a voiceprint recognition module, the processed signal undergoes feature extraction and matching. The recognition results are then transmitted to a server for further analysis, storage of the recognition data, or synchronization with other security systems via a communication and data storage module. A battery powers the terminal, ensuring its stability. Ventilation vents allow outside air to flow into the casing, dissipating heat generated by the electronic equipment inside. Clips allow operators to easily remove the cover, facilitating regular inspection and maintenance of the electronic equipment and enhancing usability. Attached Figure Description
