Abstract
Electronic clock is the use of electronic technology to make clock electronic and digital. With a precise clock, small size and can be able to develop strong performance characteristics, so are widely used to live and work.
In this paper, to achieve a normal display time with 24h/12h system adjustments, with the AM/PM display and time calibration function of a simulation based on single chip multi-function electronic clock.
In his paper the design requirements of the function are analyzed pared, determined to provide power, interface display, input program. This design adopts AT80C51 chip as the core, with a clock circuit, reset circuit, using Proteus es with the electronic clock assembly to achieve a high degree of simulation result. Software part mainly uses a wide range of C51 language. This simulation electronic clock has the advantages of simple circuit, convenient reading, visual display, multiple functions, high precision ,simple operation, time programming is easy, low cost and many other advantages.
The design is mainly use Proteus software to realize the electronic tube simulation circuit. After modification, adding some functions to produce products that can be applied to people’s life and production,in line with the development trend of electronic instrumentation, and has broad market prospects.
