Modular intelligent and safe meter box for gas meter

Abstract

The invention discloses a modular intelligent and safe meter box for a gas meter. The meter box comprises a meter box body, wherein the meter box body comprises a box body with an opening formed in the front end surface and a box cover; guide grooves for mounting the gas meter and tying bands for tying the gas meter are arranged on two side walls inside the box body; the box cover covers the opening of the box body, and a magnetic-sensitive switch is arranged between the box cover and the opening; a first notch is formed in the box body for mounting of a liquid crystal display; a second long and narrow notch is formed in the box body; a groove for mounting a control PCB (printed circuit board) is formed in the back of the box cover; a card reader corresponding to the second notch is arranged on the control PCB; the control PCB is connected with the liquid crystal display and comprises a control module, a GSM module, a storage module, an alarm module, a metering module and an RTC module, and the magnetic-sensitive switch is connected with the alarm module and the GSM module. The meter box can be assembled with any gas meter, and the safety of the gas meter can be enhanced for prevention of gas stealing and leaking behavior; meanwhile, network intelligence is realized on the meter box, so that informatization of gas management can be realized.

Description

technical field [0001] The invention relates to a gas industry control meter, in particular to a modular gas meter intelligent safety meter box. Background technique [0002] The gas meter is a flow measuring instrument used to accumulate the total volume of gas flowing through the pipeline. There are two metering boxes in the watch, and each box is equipped with a leather bag with a certain volume made of oil-soaked thin sheepskin or synthetic rubber. When the gas flows through, the bladder expands and contracts, thereby changing the volume between the bladder and the metering box, and changing the position of the slide valve at the same time. The gas of the volume of the two metering boxes is discharged, and at the same time, the crank swings once to drive the gear to rotate, and the rotation of the gear drives the counter. The reading of the counter is the volume of discharged gas. [0003] With the advancement of science and technology, it is no longer satisfied with ...

AI Technical Summary

Problems solved by technology

However, the cost of smart gas meters with multiple functions is high, and the forms and functions are also diverse.

This has led to the inability of smart gas meters to be used in a wide range of uniformity

This has also led to some functions of the smart gas meter, such as the online query function, which cannot be realized

[0004] In addition, the existing gas meter safety system design still has flaws

The exposed gas meter is easy to destroy the structure or modify the external pipeline, so that criminals can achieve the purpose of stealing gas and leaking gas
