A gas data acquisition device and data acquisition method based on single-wavelength reflection

Abstract

The invention discloses a gas data collection device and data collection method based on single-wavelength reflection. The device includes a single-chip microcomputer, a wide-spectrum light source, an optical fiber, a sensor group, and several user meters. Each user meter is connected to a wide-spectrum light source and a sensor through an optical fiber. group, the sensor group is connected to the single-chip microcomputer, and the user table includes several dials that are only used to represent different numbers. Each dial is provided with a number of numbers and the surface of the dial is coated with reflective films of different wavelengths corresponding to each number. Broad-spectrum light source and sensor group, the present invention transmits household gas degree information to an area far away from gas through optical fiber, and a high-precision photoelectric sensor is used to read each wavelength value at the optical fiber output port to obtain the gas degree information on the dial. After the mature electrical signal processing and communication transmission system for remote transmission, local non-electric collection and remote transmission of gas data can be realized, which can be used for smart meter reading and settlement, saving a lot of human resources.

Description

technical field [0001] The invention relates to the technical field of gas data acquisition, in particular to a gas data acquisition device and data acquisition method based on single-wavelength reflection. Background technique [0002] Optical fiber, or optical fiber, is a light-transmitting tool made using the principle of total reflection of light in fibers made of glass or plastic. An optical fiber is generally a symmetrical cylinder with a multi-layer dielectric structure composed of a core, cladding and coating. Optical fiber communication has many advantages such as wide transmission frequency bandwidth, large communication capacity, low transmission loss, long relay distance, and strong anti-electromagnetic interference performance. Gas is the general term for gaseous fuel, which can be burned to release heat for use by urban residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and c...

AI Technical Summary

Problems solved by technology

In the use of household gas, due to safety considerations, electrical signals cannot be used for gas data collection, which requires the traditional manual meter reading to report the gas consumption, and the embarrassing situation of "not meeting at the door" often occurs, seriously Affect the work efficiency of relevant personnel
