基于单片机的自动无线抄表系统设计：硬件、软件全面设计，提高效率和管理决策。

The traditional manual meter reading method used by water and electricity supply departments for user meter readings has long been time-consuming, labor-intensive, and lacking in accuracy and timeliness. It hinders the department from conducting deeper analysis and management decisions. In the process of industry informatization, the automatic meter reading of household data is of great significance. This design comprehensively designs the wireless meter reading system from the hardware and software perspectives. The hardware design includes the design of components such as the single-chip microcomputer minimum system, data display module, data acquisition module, signal transmission module, and serial communication. The software design includes five major modules: main program, display program, pulse counter subroutine, keyboard program, and serial communication subroutine. The system's required functions are completed through coordinated work between the hardware circuit and software design. The hardware circuit adopts the CC400 single-chip integrated wireless transceiver chip and the 89C51 single-chip microcontroller as the core, supplemented by appropriate peripheral circuits. The handheld device has keyboard and LED display functions and can transmit the collected data to a computer via a serial port. The software design utilizes assembly language to program the entire system. This system is suitable for wireless meter reading of electricity, gas, and heat meters. By constructing an automatic meter reading system, electricity companies and property management departments have significantly improved work efficiency and economic benefits. It fundamentally solves the troubles brought to users and meter readers by household meter reading and billing, while also avoiding unnecessary disputes.
