This design according to single slice machine technique principle, use single slice the machine chip AT89 C52 as core controller, pass the draw up of creation and software procedure of hardware electric circuit, design to create a multifunction and numerical clock system. the single slice machine expand of LCD display use to show second, cent, the chronometer value within few whole design include two greatly part of: Hardware part and software part, with single slice machine for core, go together with with the certain outer circle electric circuit and the hardware is the foundation of the whole system, the software is part of to then want reasonable, adequately support with usage system of hardware, plete system thus want to plete of mission. This design adoption L ED figures tube of the numeral show high with its bright degree, show to keep a view etc. the advantage be extensively been apply in realms, such as intelligence instrument and home .The clock39。s system is mainly shown that mold piece, the keyboard control mold piece and signal hint that the mold piece constitute by clock mold piece, alarm clock mold piece, the examination mold piece, LCD of the environment accurate manifestation time(manifestation format is always:The cent divide:Second second, 24 hours system), can carry on the adjustment in time at any time, have an alarm clock to establish for time, the alarm clock open/pass, make function, can carry on measure to the environment temperature of clock place and to change into instruction thought by hardware software, well exertive single slice machine function, greatly parts of functions pass a software plait a distance to carry out, electric circuit in brief clear, system stability single slice machine was born in this kind of case the machine electronics is according to the single slice clock. KEY WORDS: singlechip,lcd display, the LCD shows a mold piece,a ccording to single slice machine electronics clock. 前言 super vision in lar ge and m edium goods vehicle.
