[Abstract]:The design of this paper belongs to the basic configuration system of weak current system of intelligent residence.Highly valued by the municipal government and related functional departments, the wireless meter reading system makes up for the shortcomings of the traditional meter reading system, and facilitates the remote recording, measurement, management, and solution of the disturbance caused by the home meter reading.At the same time, it also lays a good foundation for the improvement of the automation level of household instrument management.This paper mainly discusses the research and application background of remote meter reading system, and analyzes the development of remote meter reading technology at home and abroad.This paper puts forward the important workload to be completed in this paper, designs the overall flow and scheme of the system, presents the hardware and software of each module, and discusses and implements the key technologies in the system.First of all, the characteristics and problems of some current meter reading methods are analyzed by means of comparison. It can be seen that wireless meter reading is advanced in technology, easy to realize, high transmission rate, high reliability and low cost.Easy to popularize and other advantages, will become the inevitable trend of future development.Secondly, the basic principle of ZigBee technology is deeply studied, and the protocols of physical layer, media access control layer, network layer and application layer are analyzed.In this paper, the error of the distributed address allocation mechanism of ZigBee is corrected, and a practical scheme system of wireless meter reading system is put forward according to the actual situation.The network topology diagram of the wireless meter reading system and the structure block diagram of each function module, the basic circuit diagram, and the selection and design of the main hardware module equipment are designed and planned.Finally, through the development of ZigBee platform and software programming, the related functions of ZigBee protocol network layer are realized, and the function of real-time on-line connection and data transmission between the cell concentrator and the main station of the system is realized.The remote management system of water meter based on wireless network in the whole district is completed, and the function test of each module is passed, which achieves the expected goal, meets the requirements of national technical standard, and has higher practical application value.
