Summary speaking: A chip has become a computer. Its volume is small, the quality is light, and the price cheap, for the study, the application and the development has provided the convenient condition. At the same time, the study use monolithic integrated circuit is understands the computer principle and the structure best choice. The monolithic integrated circuit interior also uses with the computer function similar module, for instance CPU, memory, parallel main line, but also has with the hard disk behave identically the memory component7 what is different is its these part performance is opposite our home-use computer weak many, but the price is also low, generally does not surpass 10 Yuan then Made some control electric appliance one kind with it is not the 'very complex work foot, We use now the completely automatic drum washer, the platoon petti-coat pipe: VCD and so on Inside the electrical appliances may see its form! It is mainly takes the control section the core part. It is one kind of online -like real-time control computer, online -like is the scene control, needs to have the strong antijamming ability, the low cost, this is also and the off-line type computer (for instance home use PC,) main difference The monolithic integrated circuit is depending on the procedure, and may revise. Realizes the different function through the different procedure, particularly special unique some functions, this is other component needs to take the very big effort to be able to achieve, some are the flowered big strength is also very difficult to achieve. One is not the very complex function, if develops in the 50s with the US 74 series, or the 60s's CD4000 series these pure hardware do decides, the electric circuit certainly arc a big PCB board ! But if, if succeeded in the 70s with the US puts in the market the series monolithic integrated circuit, the result will have the huge difference. Because only the monolithic integrated circuit compiles through you the procedure may realize the high intelligence, high efficiency, as well as redundant reliability The CPU is the key component of a digital computer. Its purpose is to decode instruction received from memory and perform transfers, arithmetic, logic, and control operations with data stored in internal registers, memory, or I/O interface units. Externally, the CPU provides one or more buses for transferring instructions, data, and control information to and from components connected to it. A microcontroller is present in the keyboard and in the monitor in the generic computer; thus these components are also shaded. In such microcontrollers, the CPU may be quite different from those discussed in this chapter. The word lengths may be short, the number of registers small, and the instruction sets limited. Performance, relatively speaking, is poor, but adequate for the task. Most important, the cost of these microcontrollers is very low, making their use cost effective. Because the monolithic integrated circuit to the cost is sensitive, therefore present occupies the dominant status the software is the most preliminary assembly language7 it was except the binary machine code above the most preliminary language, since why were such preliminary must use? Why high-level did the language already achieve the visualization programming level not to use? The reason is very simple, is the monolithic integrated circuit docs not have home computer such CPU, and also has not looked like the hard disk such mass memory equipment. Inside even if a visualization higher order language compilation script only then a button, also will achieve several dozens K the sizes! Does not speak anything regarding the home use PC hard disk, but says regarding the monolithic integrated circuit cannot accept. The monolithic integrated circuit in the hardware source aspect's use factor must very Gao Caixing, therefore assembly, although primitive actually massively is using, Same truth, if attains supercomputer's on operating system and the application software home use PC to come up the movement, home use PC could also not withstand. It can be said that the 20th century surmounted three "the electricity" the time, namely the electrical time, the Electronic Age and already entered computer time. However, this kind of computer, usually refers to the personal computer, is called PC machine. It by the main engine, the keyboard, the monitor and so on is composed. Also has a kind of computer, most people actually not how familiar. This kind of computer is entrusts with the intelligence each kind of mechanical monolithic integrated circuit (also to call micro controller). , This kind of computer's smallest system only has used as the name suggests a piece of integrated circuit, then carries on the simple operation and the control. Because its volume is small, usually hides in is accused the machinery "the belly". It in the entire installment, plays is having like the human brains role, it went wrong, the entire installment paralyzed. Now, this kind of monolithic integrated circuit's use domain already very widespread, like the intelligent measuring appliance, the solid work paid by time control, the communication equipment, the guidance system, the domestic electric appliances and so on, Once each product used the monolithic integrated circuit, could get up causes the effect which the product turned to a new generation, often before product range crown by adjective---- „intelligence?, like intelligence washer and so on. Now some factory's technical personnel or other extra-curricular electronic exploiter do certain products, are not the electric circuit are too complex, is the function is too simple, and is imitated extremely easily. Investigates its reason, possibly on card, in the product has not used on the monolithic integrated circuit or other programmable logical component. 单片机简介 单片机又称单片微控制器，它不是完成某一个逻辑功能的芯片，而是把一个计算机系统集成到一个芯片上。概括的讲:一块芯片就成了一台计算机。它的体积小、质量轻、价格便宜、为学习、应用和开发提供了便利条件。同时，学习使用单片机是了解计算机原理与结构的最佳选择。 单片机内部也用和电脑功能类似的模块，比如CPU，内存，并行总线，还有和硬盘作用相同的存储器件，不同的是它的这些部件性能都相对我们的家用电脑弱很多，不过价钱也是低的，一般不超过10元即可，用它来做一些控制电器一类不是很复杂的工作足矣了。我们现在用的全自动滚筒洗农机、排烟罩、VCD等等的家电里面都可以看到它的身影～它主要是作为控制部分的核心部件。 它是一种存线式实时控制计算机，在线式就是现场控制，需要的是有较强的抗干扰能力，较低的成本，这也是和离线式计算机的(比如家用PC)的主要区别。 单片机是靠程序的，并且可以修改。通过不同的程序实现不同的功能，尤其是特殊的独特的一些功能，这是别的器件需要费很多人力气才能做到的，有些则是花人力气也很难做到的。一个不是很复杂的功能要是用美同50年代开发的74系列，或者60年代的CD4000系列这些纯硬件来搞定的话，电路一定是一块大PCB板～但是如果要是用美国70年代成功投放市场的系列单片机，结果就会有天壤之别～只因为单片机的通过你编写的程序可以实现高科能，高效率，以及高可靠性～ CPU(中央处理单元)是数字计算机的重要组成部分，其目的是对从内存中接收的指令进行译码，同时对存储于内部寄存器、存储器或输入输出接口单元的数据惊醒传输、算术运算、逻辑运算以及控制运算。在外部，CPU位转换指令数据和控制信息提供一个或多个总线并从组件连接到它。一个微控制器出现在普通电脑的键盘和检测器中，但是这些组件也被屏蔽。在这种微控制器中，与我们所讨论的CPU可能不同。字长也许更短，编制数量少，指令集有限。相对而言，性能差，但对完成任务来说足够了。最重要的是它的微控制器的成本很低，符合成本效应。 由于单片机对成本是敏感的，所以目前占统治地位的软件还是最低级汇编语言，它是除了二进制机器码以上最低级的语言了，既然这么低级为什么还要用呢,很多高级的语言已经达到了可视化编程的水平为什么不用呢,原因简单，就是单片机没有家用计算机那样的CPU，也没有像硬盘那样的海量存储设备。一个可视化高级语言编写的小程序里面即使只有一个按钮，也会达到几十K的尺寸～对于家用PC的硬盘来讲没什么，可是对于单片机来讲是不能接受的。单片机在硬件资源方面的利用率必须很高才行，所以汇编虽然原始却还是在大量使用。一样的道理，如果把巨型计算机上的操作系统和应用软件拿到家用PC上来运行，家用PC的也是承受不了的。 可以说，二十世纪跨越了三个“电”的时代，即电气时代、电子时代和现已进入的电脑时代。不过，这种电脑，通常是指个人计算机，简称PC机。它白主机、键盘、显示器等组成。还有一类计算机，人多数人却不怎么熟悉。这种计算机就是把智能赋予各种机械的单片机(亦称微控制器)。顾名思义，这种计算机的最小系统只用了一片集成电路，即可进行简单运算和控制。因为它体积小，通常都藏在被控机械的“肚子”里。它在整个装置中，起着有如人类头脑的作用，它出了 毛病，整个装置就瘫痪了。现在，这种单片机的使用领域已十分广泛，如科能仪表、实时T控、通讯设备、导航系统、家用电器等。各种产品。一旦用上了单片机，就能起到使产品升级换代的功效，常在产品名称前冠以形容词一一“智能型”，如智能型洗衣机等。现在有些工厂的技术人员或其它业余电子开发者搞出来的某些产品，不是电路太复杂，就是功能太简单且极易被仿制。究其原因，可能就卡在产品未使用单片机或其它可编程逻辑器件上。 下面是赠送的保安部 制度 关于办公室下班关闭电源制度矿山事故隐患举报和奖励制度制度下载人事管理制度doc盘点制度下载 范本 协议范本下载族谱范本下载临帖范本下载公司章程范本下载监理月检范本下载 ,不需要的可以编辑删除!!!!谢谢! 保安部工作制度 一、认真贯彻党的路线、方针政策和国家的法津法觃,按照####年度目标的要求,做好####的安全保卫工作,保护全体人员和公私财物的安全,保持####正常的经营秩序和工作秩 序。 二、做好消防安全工作,认真贯彻“预防为主”的方针,教育提高全体人员的消防意识和防火知识,配备、配齐####各个楼层的消防器材,管好用好各种电器设备,确保####各通道畅 通,严防各种灾害事故的发生。 三、严格贯彻值班、巡检制度,按时上岗、到岗,加经对重要设备和重点部位的管理,防止和打击盗窃等各种犯罪活劢,确保####内外安全。 四、、加强保安队部建设,努力学习业务知识,认真贯彻法律法觃,不断提高全体保安人员的思想素质和业务水平,勤奋工作,秉公执法,建设一支思想作风过硬和业务素质精良的保安队伍。 11、保持监控室和值班室的清洁干净,天天打扫,窗明地净。 12、服从领导安排,完成领导交办任务。 5、积极扑救。火警初起阶段,要全力自救。防止蔓延,尽快扑灭,要正确使用灭火器,电器,应先切断电源。 6、一旦发生火灾,应积极维护火场秩序,保证进出道路畅通。看管抢救重要物资,疏散危险区域人员。 九、协同本部门或其他部门所进行的各项工作进行记录。 保安员值班操作及要求 一、交接岗 1、每日上午9时和下午 19时 为交接岗。 2、交接岗时将当班所接纳物品清点清楚,以及夜班所发生的情况未得到解决的需> 面汇报。检查值班室内外的卫生状况,地面无纸屑,桌面无杂物,整齐清洁。 二、执勤 1、7:50 — 8:10、13:50 —14:10立岗迎接上班人员;12:00 — 12:20 、18:00 — 18:20立岗送下班人员。 2、值勤时做到遇见领导立岗,检查物品立岗,外来人员进出立岗。 3、门卫室值勤时,应做到坐姿端正,注规监规器的劢态,做好接待工作,值勤期间不看书报电规,听收音机。不不无关人员聊天,劝阻无关人员不要在门卫室寄存物品或打电话,禁止打瞌睡。 4、维持门口秩序,使之保持畅通。 5、熟记消防,报警,救护及内部联系电话。 三、巡逻 巡逻是防盗及发现####有不安全因素的重要 措施 《全国民用建筑工程设计技术措施》规划•建筑•景观全国民用建筑工程设计技术措施》规划•建筑•景观软件质量保证措施下载工地伤害及预防措施下载关于贯彻落实的具体措施 。 1、每天按照巡检制度定时轮流巡逻。 2、巡逻时思想集中,保持高度警惕,不吸烟,不不无关人员闲聊,幵将每一点所发生情况记录清楚,巡逻时做到勤走劢,勤思考,勤观察。发现问 题 快递公司问题件快递公司问题件货款处理关于圆的周长面积重点题型关于解方程组的题及答案关于南海问题 及时 报告 软件系统测试报告下载sgs报告如何下载关于路面塌陷情况报告535n,sgs报告怎么下载竣工报告下载 。 3、白天加强对观众区、办公区及楼道的巡逻,夜晚以机房为重点进行检查,每晚零点之后巡查不少于两次。 四、防火工作 1、严格门卫制度,严禁无关人员,将易燃易爆物品带入####。 2、发现违反安全觃定的电源和火种,应予以切断和熄灭,应报告####领导采取相关措施。 3、值勤时发现物质储存,保管不符合防火要求,消防器材移作他用及非正常使用灭火器,应及时阻止,幵报告,提请有关部门整改。 4、发生火灾先拨打 119 向消防部队报警,幵立即报告####领导。报警时简要讲清####地址,电话号码及火情,同时派人在门口接应,引导消防车进入火场,向消防人员介绍水源,总电闸部位等。
