A natural gas measuring instrument based on the Internet of Things

Abstract

The invention relates to a natural gas measuring instrument based on the internet of things. The instrument comprises a main body, a connecting pipe, a card reading mechanism and a central control mechanism, wherein the card reading mechanism comprises a card reader and a locking mechanism; the locking mechanism comprises a locking frame, a locking component and an unlocking component; a locking unit comprises a spring, a push plate, a push rod, a locking door frame and a hinge pin; the unlocking unit comprises an operation block, a first connecting rod and a second connecting rod; and a working power module comprises a working power circuit. In the natural gas measuring instrument based on the internet of things, a radio frequency card can be preserved reliably and hermetically by the locking mechanism; meanwhile, by the unlocking component, flexible unlocking of the radio frequency card is realized, so that the practicability of a detecting instrument is improved; moreover, in the working power circuit, the stable output of supply voltage can be realized through the feedback collection of input voltage and output voltage, which is performed by the integrated circuit; and the working stability and reliability of the detecting instrument is improved.

Description

technical field [0001] The invention relates to the field of natural gas measuring equipment, in particular to a natural gas measuring instrument based on the Internet of Things. Background technique [0002] With the development of science and technology and the progress of society, people's demand for energy is getting higher and higher. The excessive use of traditional energy such as coal and oil will not only fail to regenerate, but will also bring great pollution to the environment; so people begin to pay attention to Development and utilization of new energy sources. [0003] As a new energy source, natural gas is widely used. In the process of using natural gas, it is necessary to monitor the natural gas in various places in real time to ensure the safe and reliable delivery of natural gas and the detection of the consumption. At this time, the support of natural gas measuring instruments is inseparable. [0004] Some of the existing natural gas measuring instrument...

AI Technical Summary

Problems solved by technology

[0004] Some of the existing natural gas measuring instruments support the radio frequency card identification function, but users need to save the radio frequency card, and often there will be omissions, so that natural gas cannot be used, which reduces the practicability of the instrument, and some of them can put the card in Inserted into the instrument, but due to long-term insertion, the connection is in the air, and the card will rust due to corrosion, making it unusable and reducing the practicability of the measuring instrument; not only that, but during the working process of the instrument, The working power supply circuit needs to output a stable working voltage, but because the working power supply circuit inside the current instrument uses a conventional voltage regulator transistor for voltage stabilization output to achieve a stable output of the power supply voltage, but when the output voltage fluctuates , due to the lack of feedback detection function, the output voltage of the power supply is unstable, which reduces the stability of the detection instrument.
