Magnetic sound signal acquisition cochlea

Abstract

The magnetic type sound signal acquisition cochlea comprises a shell, a magnet and a sound sensor, the shell is cylindrical, the front end of the shell is provided with a mounting seat, the front end of the mounting seat is provided with an opening, the magnet is annularly arranged at the opening, the inner layer of the magnet is annularly provided with a sound absorbing material, the center of the sound absorbing material is provided with a loudspeaker, the rear end of the shell is provided with a rear cover, and the sound sensor is arranged on the rear cover. The rear cover is in threaded connection with the shell, the sound sensor is fixedly arranged in the shell through the rear cover, and the signal output end of the sound sensor is connected with the signal processing system through a data line from the rear end of the shell. The device is quickly adsorbed on an equipment shell through the mounting seat to carry out monitoring, the device is quickly taken down and collected after monitoring is finished, the mounting and dismounting process is simplified, noise interference is reduced through the sound absorbing material, sound signals are enhanced through the loudspeaker, and high-quality and high-efficiency collection of equipment operation sound signals is ensured.

Description

technical field [0001] The invention belongs to the technical field of smart grid monitoring equipment, and specifically designs a magnetic suction sound signal collecting cochlea. Background technique [0002] With the rapid development of economy and technology, the requirements for power grids are also increasing, and the construction of smart grids has been highly valued. The basis of smart grid construction is to conduct comprehensive state perception and evaluation of operating power equipment, and routine monitoring such as temperature and humidity monitoring It can no longer meet the requirements, so it is proposed to provide a reliable basis for judging the operation status of the power equipment by collecting the sound signal of the power equipment, so as to ensure the healthy and stable operation of the power equipment and the power grid under intelligent monitoring. [0003] The existing sound signal acquisition device has a complicated structure, and it is troub...

Problems solved by technology

[0002] With the rapid development of economy and technology, the requirements for power grids are also increasing, and the construction of smart grids has been highly valued. The basis of smart grid construction is to conduct comprehensive state perception and evaluation of operating power equipment, and routine monitoring such as temperature and humidity monitoring It can no longer meet the requirements, so it is proposed to provide a reliable basis for judging the operating status of the power equipment by collecting the sound signal of the power equipment, so as to ensure the healthy and stable operation of the power equipment and the power grid under intelligent monitoring

[0003] The structure of the existing sound signal acquisition device is complicated, installation and disassembly are more troublesome, and due to the limitation of the operating environment and noise pollution, the effect of the sound signal acquisition device on the sound signal collection is greatly reduced
