| As the high development of science and technology, embedded technology has been used in our study and work, production and every part of life. In the1990th, the internet of things started to develop, and now, the perfect coalition of embedded system and internet of things, plays a great role to the improvement of people’s living standard and society development.Based on application of embedded technology and wireless communication technology, this thesis tries to make full use of high real-time, strong specificity and stable operation of the embedded system. Choosen the embedded system as the wireless communication platform, and empoldered on the basis of STM32core processor and NRF24L01wireless communication module, we intend to realize the application of Automatic Meter Reading System.Through the contrasts of different methods, this thesis introduces the present situation of Automatic Meter Reading System, and takes RF module as the wireless communication module. The system has the advantage of saving manpower and material resources, and can improve the work efficiency. The first part is hardware, the core part bases on the STM32processor, which can control SPI, LCD display, NRF24L01module. The second part is software, including the data transmission of wireless module and μC/OS-Ⅱ transplantation. The research and practice have proved: the two parts above can well realize Automatic Meter Reading System which will be the future development trend of meter reading system. Finally, we summarize the work of this thesis, and put forward the existing problems and future research. |
