Aiming at the problems of short transmission distance

small coverage range and more base stations are needed in intelligent gas meter control system of wide area internet of things

a wireless intelligent gas meter based on narrow-band Internet of things（ NB-IoT） transmission mode is proposed. The system uses KL36 as micro controller

uses BC95 wireless module to realize function design

and gives the detailed hardware and software design method of control system. The test results show that the NB-IoT technology overcomes the problems exist in wide area Internet of things

and has the advantages of stability and reliability

it has good prospect and application value.
