摘 要


隨著單片機(jī)的日益發(fā)展，其應(yīng)用也越來(lái)越廣泛，通過(guò)對(duì)“汽車轉(zhuǎn)彎燈單片機(jī)控制系統(tǒng)”設(shè)計(jì)，可以對(duì)單片機(jī)的知識(shí)得到鞏固和擴(kuò)張。本設(shè)計(jì)是設(shè)計(jì)一個(gè)單片機(jī)控制系統(tǒng)。在汽車進(jìn)行左轉(zhuǎn)彎、右轉(zhuǎn)彎實(shí)現(xiàn)對(duì)同步照明燈的控制。本設(shè)計(jì)主要是對(duì)單片機(jī)的并行輸入/輸出口電路的應(yīng)用，通過(guò)I/O口，加上一些復(fù)位電路﹑按鍵電路﹑驅(qū)動(dòng)電路來(lái)模擬汽車同步燈的同步跟隨功能。
汽車在駕駛時(shí)有左轉(zhuǎn)彎、右轉(zhuǎn)彎等操作。在左轉(zhuǎn)彎或右轉(zhuǎn)彎時(shí)，通過(guò)轉(zhuǎn)彎操作桿應(yīng)使前輪左轉(zhuǎn)，從而使同步燈跟隨轉(zhuǎn)向閃爍；汽車在直線行駛的時(shí)候，同步照明燈可以當(dāng)成前照燈的輔助，也就是說(shuō)當(dāng)前照明燈在亮著的時(shí)候，同步照明燈也是亮著的，以便在轉(zhuǎn)向的時(shí)候，不必要再次啟動(dòng)。在汽車停止的時(shí)候，只要前照明燈亮著，同步燈也亮著。通過(guò)做實(shí)物，編寫(xiě)程序，完成了設(shè)計(jì)的要求。通過(guò)該設(shè)計(jì)，對(duì)單片機(jī)的認(rèn)識(shí)有了更進(jìn)一步的了解，對(duì)單片機(jī)的各個(gè)口的功能作用了解加深，對(duì)Protel的應(yīng)用更加熟練，對(duì)設(shè)計(jì)系統(tǒng)有了了解，掌握了一些設(shè)計(jì)方法，受益不少。

ABSTRACT


With more monolithic integrated circuits, the more extensive, "the car turned the" monolithic integrated circuits to control system design, can the information to monolithic integrated circuits has been consolidated and expanded. this design is to design a monolithic integrated circuits to control system. in the car to turn left and right, the brakes, to open the door, called for urgent action to implement the various signal sign of control. this design is primarily to monolithic integrated circuits of the export of the circuit in parallel lost. i turned around and control of light through And bright, shining out, and some clear, and buttons, the driving circuit circuit to a function of the taillights. the car was driving up turn left and right, the brakes, to open the door, called an emergency operations. in turn left or right, through the turn of the operation should be left or right switch to switch on the left, the dashboard turn left or right and left the taillight the instrument panel lamp, and turning right, the right rear lights flickered ； switch to the emergency requires that the previous 。The six the light shone in the car braked all ；, two of the taillights like a light ； just round the corner, the corners of the original signal shall be still flickered. the above, are the frequency of the low frequencies 1hz ； in a car and close at the switch when, right and left the taillight, the right rear lights for the frequency of high frequency a 30hz. by doing physical, program, completed the design demands. the design of a monolithic integrated circuits has further the

Key words monolithic integrated circuits ； the car turned the light signals ； basic techniques of digital circuit ； electronic
