Aiming at the problems of data falsification

short communication distance between the collection terminal and the base station

remote detection points

and unstable data transmission in places where the network signal is poor

a narrow-band Internet of Things（NB-IoT）static load detector system.The main hardware and software parts of the system’s data acquisition terminal and data receiving base station are introduced.The main hardware of the collection terminal and the receiving base station includes the STM32 main control module

analog to digital（A/D）conversion module

oil pump control module

wireless serial port module

BC26 communication module

GNSS positioning module

data storage module

etc; software mainly includes the main program module of the data collection terminal

Data receiving main program module of base station

etc.Tests and applications show that the system has a long transmission distance

the data upload is stable and reliable

the data is directly transmitted to the quality inspection center

and data fraud cannot be performed.
