系統(tǒng)硬件電路 1.電源部分 單片機(jī)工作需要+5V的直流電，所以電源部分是將220V的交流電通過變壓器轉(zhuǎn)換成9V交流電，再通過整流橋轉(zhuǎn)換成+5V直流電。此時+5V直流電很不穩(wěn)定，不符合單片機(jī)工作的需求，因此還須將電流通過濾波電容和集成穩(wěn)壓塊7805，逐步達(dá)到穩(wěn)壓、濾波的作用。 2.單片機(jī)（CPU）控制部分 單片機(jī)控制部分是整個智能燈光控制器核心，沒有這個部分，那智能燈光控制器就不“智能”了。它的CPU是單片機(jī)AT89S52，有40個引腳，足夠我們的智能臺燈的需求。晶振系統(tǒng)分別接在18腳（XTAL2）和19腳（XTAL1），復(fù)位系統(tǒng)接在9腳（RESET）。 CPU和晶振的關(guān)系就如大腦與心臟一樣，如果心跳不穩(wěn)定，那大腦也不會工作的很好。晶振就能提供很穩(wěn)定的頻率，使得CPU能很好的工作。 3.部分 系統(tǒng)分為發(fā)射與接受兩個部分，發(fā)射部分就是。接受部分能接收到發(fā)射的紅外線。（與人置檢測的紅外線發(fā)射管共用紅外接收頭）
