Direct-reading wireless gas meter based on illumination-vibration complementary environment energy collecting technology

Abstract

The invention discloses a direct-reading wireless gas meter based on the illumination-vibration complementary environment energy collecting technology. The direct-reading wireless gas meter comprises a membrane type basic gas meter, three direct-reading infrared encoders, three 7 to 1 switch modules, an infrared encoding collecting and data processing module, an illumination environment energy collecting and communication module, a vibration environment energy collecting module and the like. The three direct-reading infrared encoders output analog quantity encoding values, and gas digital quantity data is uploaded to the illumination environment energy collecting and communication module through the three 7 to 1 switch modules and the infrared encoding collecting and data processing module. The direct-reading wireless gas meter has the advantages the electric energy of the gas meter is taken from the environments, and the illumination-vibration complementary environment energy collecting scheme designed according to power demands is good in usability; a single-ring semicircular encoding process is simple, and convenient in error correction; environment energy collecting efficiency is increased by a micro power consumption management circuit; an EnOcean standard protocol low in wireless communication frequency is good in diffraction ability; environment energy utilization is optimized by a polarized relay and the interrupt awakening technology.

Description

technical field [0001] The invention belongs to the technical category of automatic meter reading of gas meters, in particular to a direct-reading wireless gas meter based on the technology of collecting light and vibration complementary environmental energy. Background technique [0002] With the continuous advancement of the urbanization process and the continuous improvement of housing conditions, a large number of high-rise residential buildings have emerged, and they have gradually become the mainstream form of living; with high-rise residential buildings, the difficulty of meter reading for water, electricity and gas meters has also increased. Through decades of unremitting efforts in the industry, the problem of hydropower meter reading has been solved or alleviated to a considerable extent. The day when Hangzhou implements one meter per household is the time when the problem of meter reading of water meters will no longer exist. In addition, one meter per household i...

Problems solved by technology

The day when Hangzhou implements one meter per household is the time when the problem of meter reading of water meters will no longer exist. In addition, one meter per household is conducive to the improvement of water supply quality, so residents are willing to pay for "one meter per household"; new high-rise residential buildings in Hangzhou The standard configuration of centralized electric meter screen solves the problem of meter reading of electric meters; only the meter reading of gas meters is struggling, and there is no improvement! Pipeline natural gas in Hangzhou is developing rapidly. In 2012, there were more than 570,000 pipeline natural gas users, an increase of 8.95% compared with 2011. However, the meter reading mode of Hangzhou Pipeline Natural Gas Company is still the same today: meter readers regularly visit households to read meters on the spot

As an important part of national public utilities, gas is an indispensable energy source in residents' daily life; gas meters are different from water and electricity meters, and from the perspective of safety in use, they are not allo
