today, It is very important to read data from meter by
automatic means.
The design of hardware, software, two wireless
meter reading system in terms of overall design.
Among them, the hardware design include: the
smallest single-chip systems, data display module, data
acquisition module, signal transmission, such as serial
communication module and the design of components.
Software design, including the main program, display
program, pulse counter subroutine, keyboard
procedures, serial communication subroutine these five
modules. Through the hardware circuit and software
design of the system to coordinate the completion of
all the features required. CC400 hardware single-chip
integrated circuit chip wireless transceiver and 89C51
single-chip microcomputer as the core, with
appropriate external circuitry, handset with a keyboard
and LED display, and through the serial data will be
copied to the computer. Software design using
assembly language programming to the entire system.
The system applies to electricity, gas, wireless
Collecting heat. Through the construction of automatic
meter reading systems to power companies and
property management sector greatly enhanced the
efficiency and cost-effective and fundamental solution
to the house meter reading and meter reading charges
to the user the trouble of staff, but also to avoid the
unnecessary disputes.
