【正文】 s, and the mon model number factory price drop into to USD 1, tallest carry of model number also only USD contemporary and single slice machine system has already no longer developed and used just under the naked machine environment, the in great quantities appropriative builtin operate system is applied extensively in the whole series of the single slice is on board. But Be the high level of handheld PC and cellular phone core processing single slice the machine even can use appropriative Windows and the Linux operate system directly. Single slice the machine ratio appropriation processor is the most suitable to match to apply in the builtin system, so it got the most applications. In fact the single slice machine is an amount the most calculators are in the world. The modern mankind are living medium use of assemble in almost each electronics and machine product have a single slice machine. All have 12 single slice machine in the puter access ories such as cellular phone, telephone, calculator, home appliances, electronics toy, handheld PC and mouse etc.. And personal puter in would also capable number not a few single slice the machine be working. Provide with more than 40 departments a single slice machine generally on the car, plicated industry39。此外，還有實(shí)驗(yàn)室做畢業(yè)設(shè)計(jì)的張苗源、劉少華、余秋宏等同學(xué)，在這幾個(gè)月中，大家互相幫助、共同學(xué)習(xí)，這段時(shí)光我將永生難忘!感謝所有給予過(guò)我支持和幫助的朋友們!河南科技大學(xué)本科畢業(yè)設(shè)計(jì)（論文）32附 錄電路原理圖R10RES2R12RES2R8RES2D5LEDD4LEDD3LEDD2LEDD1LEDC3 CAP C2 CAPR11RES2R1RES2R9RES2S6SWPBS5SWPBS2SWPBS1SWPBD6DIODE123J3 CON31234J2 CON412J1 CON2OC1C11D22D33D44D55D66D77D88D91Q192Q183Q174Q165Q156Q147Q138Q12U3 74HC573R2RES2R3RES2R4RES2R5RES2R6RES2S4SWPBR21S3SWPBR22X1CRYSTALR23C4ELECTRO1R24K1 RELAYSPDTR25C110UFR26R7RES2R27R28B1B2B3B4B5VCCVCCVCCTXDRXDGNDC5CAPVCC GNDVCCGND123J4 CON3K2 RELAYSPDT123J5 CON3K3 RELAYSPDTVCC40393837363534332EA/VPP31ALE30PSEN2928272625242322112345678RST9101121314151617XTAL218XTAL119VSS20U1 AT89C52GNDGNDB1B2B3B4B5VCCIN11IN22IN33IN44IN55IN66IN77IN88COM9OUT118OUT217OUT316OUT415OUT514OUT613OUT712OUT81DIODE10U21D2D3D4D5D6D7D8DGNDVCCGNDVCCVCCVCCRXDTXDOUT18OUT17S4S5S6S6S5S4S3S2S1R19 RES217 RES2R18 RES216 RES215 RES214 RES213 RES220 RES2D7D6D5D4D3D2D1D0a bf cg deDPY1234567a b c d e f g8dpdpLED1DPY_7SEG_DPa bf cg deDPY1234567a b c d e f g8dpdpLED2DPY_7SEG_DPD7D6D5D4D3D2D1D0D7D6D5D4D3D2D1D0OUT18OUT17河南科技大學(xué)本科畢業(yè)設(shè)計(jì)（論文）33英文原文：The Introduction of AT89C51Background8 AT89C51 the CHMOS craft monolithic integrated circuit is designed uses in to process the high speed putation and the fast input/output. The MCS51 monolithic integrated circuit model application is the high speed event control system. Commercial use including modem, motor control system, printer, photogravure press, air conditioning control system, disk driver and medical equipment. The automobile industry uses in the engine control system the MCS51monolithic integrated circuit, the suspension system and locks on the other side the braking system. AT89C51 especially very good is suitable from benefits from on its processing speed and the enhancement piece the periphery function collection, such as: The automobile power control, the vehicles dynamic are hanging, lock on the other side apply the brake with the stable control application. As a result of these decisive applications, the market requirement one kind reliable has lowly disturbs the expense potency controller which the ambush responds, the service massive time and the event actuates the integrated periphery ability which needs in the realtime application, has outdoes the average processing power in the sole routine package the central processor. Has the equipment economy and the legal risk which the operation cannot be forecast are very high. Once enters the market, especially the duty decisiveness application such as autopilot or locks on the other side the braking system, will be wrong will be in the financial resource forbids. The redesign expense may reach as high as 500K US dollar. The single slice machine is also called tiny controller, is because it was used in the industry to control realm at the earliest stage. Single slice machine from inside chip have CPU appropriation processor to develop only since then. At the earliest stage of design the principle is to pass to integrate a great deal of peripherals and CPU in a chip, making calculator system smaller, integrating more easily into plicated of but to mention to request a strict control equipments in the middle. The INTEL Z80 is the processor which designed according to this kind of thought at the earliest stage, from now on, single slice the development of the machine and appropriation processor went by different roads then. The single slice of the earlier period all of machines are 8 or them, the INTEL is most successful of 8031, because of in brief dependable but the function was quite good to acquire very big good opinion. Henceforth at 8031 up developed MCS51 series a 河南科技大學(xué)本科畢業(yè)設(shè)計(jì)（論文）34single slice machine system. According to the single slice of this system machine system is still in the extensive usage till now. Because the industry controls the exaltation of[with] realm request, starting appearing 16 single slice machine, but because sex price wanted to don39。近半年來(lái)，王老師在學(xué)習(xí)、工作和生活方面都給予了我無(wú)微不至的關(guān)懷，她淵博的知識(shí)、積極樂(lè)觀的人生態(tài)度、忘我的工作精神都令我十分欽佩。此次設(shè)計(jì)雖然已經(jīng)基本完成，但尚有一些不足的地方，例如，添加一個(gè)報(bào)警模塊，當(dāng)定時(shí)器結(jié)束時(shí)，進(jìn)行報(bào)警。本設(shè)計(jì)期間主要開(kāi)展了一下方面工作：通過(guò)硬件電路設(shè)計(jì)了解了 AT89C52 單片機(jī)的結(jié)構(gòu)和特點(diǎn)，
