Contact type equipment vibration sound sensor

Abstract

The invention discloses a contact type equipment vibration sound sensor which comprises a sensor base and a shell, the sensor base and the shell are fixedly matched to form a sound cavity, and an electric connection part is arranged on the shell; one side, close to the shell, of the sensor base is provided with a detection table, the detection table is located in the sound cavity, the detection table is connected with the sensor base through a connecting piece, and a gap is formed between the detection table and the sensor base; a damping insulation pad is arranged on one side, far away from the sensor base, of the detection table, and an acoustoelectric vibration conversion part is arranged on one side, far away from the detection table, of the damping insulation pad; and the acoustoelectric vibration conversion part is electrically connected with the electric connection part. The contact type equipment vibration sound sensor has the advantages of being high in intelligent degree and rich in application scene.

Description

technical field [0001] The invention relates to the technical field of equipment monitoring, in particular to a contact-type equipment vibration and sound sensor with high intelligence and rich applicable scenarios. Background technique [0002] In the process of equipment working status monitoring and fault diagnosis, since the equipment will emit different sounds under different working conditions, it is an economical and simple method to judge the equipment status through the sound emitted by the equipment when it is running. However, the traditional way of judging equipment status through sound requires inspectors to directly listen to the sound of the equipment. The experience requirements for inspectors are extremely high and there is no good recording method. They can only rely on human memory and feeling. In addition, in order to ensure that inspectors enter the equipment to work On-site safety, for some equipment working in harsh environments, status monitoring and ...
