The Design of Intelligent Energy Consumption Acquisition System Based on Narrowband Internet of Things
This design develop an energy consumption acquisition system based on narrowband Internet of Things using stm32 series low-power microcontroller stm32f407 produced by STMicroelectronics . The system consists of Perception layer, Network layer, and Application layer. The Perception layer includes an intelligent collection terminal. The Network layer upload data to the server through Low Power WAN. The Application layer achieve intelligent monitoring of remote nodes. The system not only meets the requirements of acquisition and transmission in industrial environments, but also can be applied to terminal data collection and transmission requirements in many different networks such as building networks and home networks. The system hardware design adopts the modular circuit design method, which mainly includes: the minimum system board of the microcontroller, the power management module, the clock circuit module, the data storage module, the narrow-band IoT module. The system software design adopts the service-level hierarchical programming idea. For the different modules, write the corresponding driver code; according to different protocols, write the corresponding communication protocol code. Since the design is based on industrial control site requirements, the system uses industrial design standards. The system runs well and is suitable for two-way remote meter reading system in industrial control field.
