"基于单片机的无线自动抄表系统设计与实现"

The traditional manual meter reading method used by water and electricity supply departments for user electricity meters, water meters, and gas meters is time-consuming, labor-intensive, lacks accuracy and timeliness, and is not conducive to deeper analysis and management decision-making by supply departments. In the process of industry informatization, the automation of household meter data collection is of great significance. This design comprehensively designs the wireless meter reading system from the two major aspects of hardware and software. The hardware design includes the design of the single-chip microcomputer minimum system, data display module, data acquisition module, signal transmission module, and serial communication components. The software design includes the main program, display program, pulse counter subroutine, keyboard program, and serial communication subroutine. Through the coordinated work of hardware circuits and software design, all the functions required by the system are completed. The hardware circuit uses the CC400 single-chip integrated wireless transceiver chip and the 89C51 single-chip microcomputer as the core, equipped with appropriate peripheral circuits. The handheld device has keyboard and LED display functions and can transmit the collected data to the computer through the serial port. The software design uses assembly language to program the entire system. This system is suitable for the wireless collection of electricity, gas, and heat meters. By constructing an automatic meter reading system, power companies and property management departments have greatly improved work efficiency and economic benefits. It fundamentally solves the troubles caused to users and meter readers by manual meter reading and charging, and also avoids unnecessary disputes. Keywords: single-chip microcontroller; CC400; LED
