Design of remote wireless collection system for multi-meter based on narrow band Internet of Things

In view of the short transmission distance, small coverage, poor penetration, and poor data transmission stability of the current instrument system, this paper proposes a design scheme for a multi-instrument remote wireless acquisition system based on narrowband Internet of Things. In terms of hardware, it mainly includes STM32 main control module, acquisition module, BC95 wireless communication module and power supply module, etc.; software mainly includes BC95 module communication module and concentrator main control module. The collected multi-meter data is sent to the upper management system using narrowband Internet of Things communication technology to realize remote data reading of multiple meters. Through experiments, the influencing factors of the upload rate of the wireless water meter collection system are studied, and it is verified that the upload rate of the wireless collection system designed in this paper meets the usage requirements.
