Optical and electric device containing cabinet with noise reduction function for optical fiber vibration sensing detection

Abstract

The invention discloses an optical and electric device containing cabinet with a noise reduction function for optical fiber vibration sensing detection. The cabinet comprises a cabinet body, the uppersurface of the cabinet body is fixedly connected with a controller, a plurality of layers of containing plates are fixedly connected to the interior of the cabinet body, the front surface of the cabinet body is rotationally connected with a sealing door through a hinge, and the edge of the front surface of the cabinet body is connected with an anti-noise plate in an embedded manner. A communication box is fixedly connected to the bottom end of the side face of the cabinet body through bolts, an infrared emitter is fixedly connected to the upper side, close to the containing plate, of the inner wall of the cabinet body, and monitoring equipment is fixedly connected to the side, close to the infrared emitter, of the inner wall of the cabinet body. The invention relates to the technical field of optical fiber equipment. According to the optical and electric device containing cabinet with the noise reduction function for optical fiber vibration sensing detection, two noise reduction modesof a noise prevention plate and sound absorption cotton are adopted, the sound absorption cotton is convenient to mount and dismount, and therefore workers can conveniently overhaul and replace the sound absorption cotton, and the noise prevention plate is connected with the cabinet body through permanent magnets in an adsorption mode.

Description

technical field [0001] The invention relates to the technical field of optical fiber equipment, in particular to a storage cabinet for optical and electrical devices with a noise reduction function for optical fiber vibration sensing and detection. Background technique [0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic. It can be used as a light transmission tool. Its transmission principle is "total reflection of light". Part of the characteristics of the transmitted light will change. By configuring special sensing equipment, after signal collection and analysis, the optical fiber vibration monitoring module is often used for real-time monitoring when the optical fiber is used. When the optical fiber is used for vibration detection, multiple optical and electrical appliances are required. Components, optical and electrical components are usually stored in special storage cabinets during normal storage or work. [0003] Chin...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a storage cabinet for optical and electrical devices with a noise reduction function for optical fiber vibration sensing detection, which solves the problem that the existing storage cabinet has a single structure and has a relatively low noise reduction function for external noise. Weak, and the interior of the device needs to keep the cabinet dry while maintaining air circulation to prevent excessive moisture from affecting the optical and electrical devices. At the same time, when the optical and electrical devices are used or stored, they need to be monitored to prevent external The impact of vibration or impact on optical and electrical devices
