What is WLAN ?The term wireless means any technology which is used without anv hard wired connection, such as Bluetooth, GSM/GPRS, and 3G. Among all, the wireless technology broadly refers to the WLAN, as is “Wireless Local Area Network： which links more than two devices without entangling wires.The wireless network enables you to surf the internet anywhere in the house・ You can save both the cost of extra Ethernet cables and times to set up the network. All you n eed to do is in stall the adapter and upgrade your PC into the wireless n etwork; you can then enjoy the ben efit of it.What is Wi-Fi ?The Term “Wi・Fi”，as short for ”Wireless Fidelity”, is invented by the Wi・Fi Alliance, which is intended to improve the interoperability of wireless local area network products.“Wi・Fi” was originally referring to the Wi-Fi Alliance and the Wi-Fi Certification applicable only to 802.11b standard. Today it is broadly referring to any of the IEEE 802.11 WLAN Standards, including 802.11b, 802.11a, 802.11g, and the latest 802.11n standards. (See What are WLAN stan dards?)Wi-Fi Alliance and Wi-Fi CertifiedThe Wi-Fi Allia nee is a nonprofit inter national association to certify a set of interoperable WLAN products based on the IEEE802.11 standards・Manufacturers that are members of Wi-Fi Alliance and whose products pass the interoperability tests hold by the Wi-Fi Alliance will be approved as “Wi-Fi Certified" and can mark their products with the Wi-Fi logo. Meanwhile a user who carries a fl Wi-Fi Certified H product can use any brand of access point with any other brand of client hardware that also is certified.What are WLAN standards ?WLAN Standards is also known as the IEEE802.11 technologies developed by the IEEE (Institute of Electrical and Electronics Engineers, Inc), which specifies an over・the・air interface between the client and base station or two wireless clients. According to different encryption and data rate,IEEE802.11 technologies mainly consist of 802.11b, 802.11 a, 802.11g, and 802.11 n.802.11bThe 802.11b specification was the first widely accepted wireless networking standard. It operates in the 2.4 GHz ISM band, and has a maximum speed of 11Mbps within the range up to 50 meters.Since 802.11 b operates at the frequency of 2.4GHz as the comm on cha nnel freque ncy, it can be interfered with obstacles like microwave or cordless phones.802.11aCompared with 802.11b, the 802.11a specification operates at the frequency of 5 GHz, which can be less affective by other devices in the crowded 2.4GHz range. It speeds up to 54Mbps better than the 11 Mbps as 802.11 b, but performs within the range only up to 30 meters.802.11a is incompatible with both 802.11b/g as they operate on separate bands; except if using devices that provide dual band functionality.802.11gThe 802.11g specification operates at the frequency of 2.4GHz, the same as 802.11b. But compared with 11 Mbps for 802.11b3 802.1 1g offers transmission up to 54Mbp like 802.11a does.Since the 802.11b and 802.11g works at the same frequency, the equipment with both specifications is interoperable. The 802.11g is backward compatible with 802.11b so that devices with 802.11g specification also work with 802.11b.However, 802.11g and 802.11b both suffer from the same interfere nee of crowded 2.4 GHz band. The performance might be affective by other devices like microwave, Bluetooth devices, and cordless phones.802.11n (draft 2.0)802.11 n specification is the next generatio n of 802.11 Wi-Fi tech no logies. It is estimated to deliver at the maximum speed of 600Mbps, within range of 100 meters.802.11 n is backward compatible with 802.11 b/g standards as well as supports high-data rate tran smission applications like HD video or audio streaming, garni ng and more.Comparison for 802.11a/b/g/n•802.11a suffers less from sign al integrity and supports 54Mbps over a relatively short distance. •802.11 n performs up to 5 times faster and 2 times farther than 802.11g.How does 802.11 n work ? (About the MIMO Technology)Building on previous 802.11 standards, 802.11 n adds the MIMO technology. MIMO stands forc<Multi-lnput Multi-Outpuf and uses multiple transmitter and receiver antennas to improve the performs nee of radio communicati on systems.In MIMO there can be a separate RF chai n for each antenna allowing multiple chai ns to coexist, so the MIMO system can process more signals and accommodate more data as multiple radio signal are carried on the same frequency simultaneous!y・ These allow the wireless network to improve the speed and throughput as well as reduce the dead spots without additional bandwidth or transmit power.Is wireless network secure?One con sideration of the wireless n etwork is securit y. Some of the main tech no logies to preve nt attackers from home network are as following:1. WEPWEP is short for the Wired Equivalent Privacy and refers to a security protocol for WLAN defined in the 802.11 b standards・ It is designed to provide the same level of security similar to that provided by the physical security inherent in a wired LAN. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another.Since WEP was an early encryption technique to secure Wireless connection, some of its weakness has been identified・ It was then superseded by Wi-Fi Protected Access (WPA) and 802.11i (also know as WPA2) for better security. In spite of its weakness, WEP is capable of a level of security to prevent casual snooping・ WEP is usually presented as the first security choice in most installation instructions.2. WPAWPA (Wi-Fi Protected Access), based on the IEEE802.11i draft 3, is wireless security greater protection than WEP. WPA serves as an intermediate solution between WEP and 802.11i networks, and hasbackward compatible WEP supports for older devices・WPA adds authentication to WEP's basic encryption. It operates in either WPA-PSK mode (aka Personal mode) or WPA-802.1x mode (aka Enterprise mode). The Personal mode uses a pre-shared key (PSK) for authentication with less security since every user is given the same passphrase, while the Enterprise mode uses an IEEE802.11x authentication server for better securit y.WPA uses Temporal Key Integrity Protocol (TKIP) mechanism. TKIP dynamically changes keys as the system is used. This is difficult for hackers to read messages so as to improve the security in the WPA over WEP.3. WPA2WPA2 is the following security protocol to WPA and backward interoperable with WPA. WPA2 operates based on the full IEEE802.11i specification.WPA2 provides support for all of the mechanisms available in WPA. Both offer a high level of assurance for end-users and network administrators that their data will remain private and access to their network restricted to authorized users. Both have the Personal and Enterprise mode of operation for the authentication.Compared with WPA, the enhanced WPA2 uses Advanced Encryption Standard (AES) in addition to TKIP. This provides a stronger encryption mechanism.http://www. azurewave, comFAQ AW-GA200Common ProblemQ: There is a message that says this device has been owned by “xxxx" and I cannot connect to it.A: On the advanced setting page of wireless audio utility, current user can lock the utility and reject the other users connecting to this device・ Hence, you cannot connect to AW-GA200.Q: What is my device9s default IP Address?A: The device's default IP address is 192.168.0.10.Q: What should I do if I forget all the default settings?A: You may reset to the default settings of AW-GA200 by pressing and holdi ng the reset butt on on the rear panel for 10 seconds then go to Setup Wizard to con figure again.Q: My Device has a wired connection to my network.

计算机控制系统的应用及发展
第一章计算机过程控制系统的应用与开展在石油、化工、冶金、电力、轻工和建材等工业生产中连续的或按一定程序周期进行的生产过程的自动控制称为生产过程自动化。
生产过程自动化是保持生产稳定、降低消耗、降低本钱、改善劳动条件、促进文明生产、保证生产平安和提高劳动生产率的重要手段，是20世纪科学与技术进步的特征，是工业现代化的标志。
但凡采用模拟或数字控制方式对生产过程的某一或某些物理参数进行的自动控制就称为过程控制。
过程控制系统可以分为常规仪表过程控制系统与计算机过程控制系统两大类。
随着工业生产规模走向大型化、复杂化、精细化、批量化，靠仪表控制系统已很难到达生产和管理要求，计算机过程控制系统是近几十年开展起来的以计算机为核心的控制系统。
1.1 计算机过程控制系统的开展回忆世界上第一台电子数字计算机于19461959年世界上第一台过程控制计算机TRW-300回忆工业过程的计算机控制历史，经历了以下几个8寸期：(1)起步时期(20世纪50年代)。
20世纪50年代中期，有人开始研究将计算机用于工业过程控制。
(2)试验时期(20世纪60年代)。
1962年，英国的帝国化学工业公司利用计算机完全代替了原来的模拟控制。
(3)推广时期(20世纪70年代。
随着大规模集成电路(LSI)技术的开展，1972年生产出了微型计算机(mi—erocomputer)。
其最大优点是运算速度快，可靠性高，价格廉价和体积小。
(4)成熟时期(20世纪80年代)。
随着超大规模集成电路(VLSI)技术的飞速开展，使得计算机向着超小型化、软件固定化和控制智能化方向开展。
80年代末，又推出了具有计算机辅助设计(CAD)、专家系统、控N*0管理融为一体的新型集散控制系统。
(5)进一步开展时期(20世纪90年代)。
在计算机控制系统进一步完善应用更加普及，价格不断下降的同时，功能却更加丰富，性能变得更加可靠。
1.2 计算机过程控制系统的分类计算机控制系统的应用领域非常厂泛，计算机可以控制单个电机、阀门，也可以控制管理整个工厂企业；控制方式可以是单回路控制，也可以是复杂的多变量解耦控制、自适应控制、最优控制乃至智能控制。

嵌入式系统是物联网产业发展的（作者：中嵌协会柏斯维）2009年8月7日**总理视察无锡时，提出在无锡加快建立“感知中国”中心的指示。
从此在国内不管是各级地方政府还是企业都很重视，并掀起了一个追逐物联网的行动热潮。
一年过去了，再一次的解读温总理的“感知中国”更具有现实意义和深远的历史意义。
嵌入式与物联网的关系温总理用经典的四个字“感知中国”全面描述和定义了物联网产业的内涵。
从字面上来理解，“感”既是信息采集（传感器）；“知”信息处理（运算、处理、控制、通信并通过互联网进行信息传递和控制）。
这些都是嵌入式系统的特征实质。
如果归纳一句话来理解总理“感知中国”的含义，既是通过嵌入式系统智能终端产品网络化的过程实现感知的目的。
简单讲，物联网是物与物、人与物之间的信息传递与控制。
专业上讲就应该是智能终端的网络化。
大家都知道，嵌入式系统无所不在，有嵌入式系统的地方才会有物联网的应用。
所以，我在所有的场合都在传播一个理念，什么是物联网呢？物联网就是基于互联网的嵌入式系统。
从另一个意义也可以说，物联网的产生是嵌入式系统高速发展的必然产物，更多的嵌入式智能终端产品有了联网的需求，催生了物联网这个概念的产生。
记得是在09年10月12日，英特尔公司宣布成立中国研究院并且专攻嵌入式方向。
在全球热炒物联网概念时，英特尔为什么不成立物联网研究院？而专注嵌入式的研究呢。
这是值得深思研究的课题。
那么，在2010英特尔信息技术峰会（IDF）的前一天，英特尔CTO贾斯汀和英特尔研究院方之熙院长一起宣布了英特尔中国研究院全新的研究战略——致力于打造世界一流的嵌入式系统研究院。
方院长讲到：作为英特尔研究院全球5大节点之一，英特尔中国研究院将承担嵌入式系统的前瞻性研究任务，放眼全球嵌入式增长机遇，融合国人智慧做世界级的研究，并将国际水准的研究成果直接贡献于中国的发展。
中国手机、互联网、有线电视用户人数均居全球第一，也已成为名副其实的世界第一汽车市场。

存储器那点事
存储器的那点事存储器本系列文章为WatchStor专栏约稿，属于存储器发展史系列文章，将通过对基于磁盘的存储器不同分类，以及每阶段推动其发展动力的介绍，为广大读者梳理一条存储器发展的清晰脉络，通过本文作者深刻的技术实力及行业观察力，帮助您对存储器今后的发展有个清晰的认识。
常见存储器分类知识产权, 云计算, 存储器前言注：本文中所谈到的存储器主要是指磁盘阵列，通过SAN/NAS/iSCSI等接口与主机相连，虽然说SAN交换机、物理带库、磁带机和光盘塔也属于存储的范畴，但不在本文讨论范围内。
存储器，或者称作存储阵列，是当今业界一个比较Fashion的词，见过不少这个圈子里的公司为了提高档次，会主动往存储行业靠，经常自我标榜―哥所在的系统集成公司是高科技，不仅搬箱子，哥还做存储‖，―哥公司自己生产具有完全知识产权的存储器‖…（当然现在再这么说有点out了，现在流行自我标榜―哥公司现在做云计算高科技呢‖）。
当然，这个圈子里面的人在和身边朋友自我介绍是做存储这个高科技行业时，也经常碰到另外一种情况，―哥们你们那边250G的盘多少钱一块啊，你们卖U盘么？‖…那么存储器究竟该如何定义呢？在我看来，二十多年前Sun公司提出了―网络就是计算机‖的理念，对于整个IT行业发生了翻天覆地的变化，那么我们也完全可以说―存储也是计算机‖。
存储是什么呢，对，存储也是计算机。
2000年前的存储器，多是作为主机的附属品出现的，记得97年本人在做系统管理员时，看到厂商在调试几套HP 9000和SUN小型机，几个集成商的工程师将一个个磁盘塞进一个独立架子里面（后来才知道那叫磁盘柜），一边塞进去还一边说：―哥们千万注意啊，这玩意叫磁盘阵列，贼贵，一块磁盘顶一台夏利呢‖。
我们当时大吃一惊，高科技啊，一块小铁片竟然顶得上大街上一辆出租车（其实当时也不过是给个JBOD+软件RAID，现在想想，真叫暴利啊）…而且当时安装磁盘阵列也是看起来很高深的一件事情，不同于主机UNIX操作系统要插入光盘，输入命令、不断回车，磁盘阵列的安装往往是在主机安装完后再导入一些软件，然后运行一个脚本，出去吃个饭、抽根烟….就完成了。

How to Pick the Right Microcontroller Based on Low-PowerSpecificationsIntroductionChoosing the right ultra-low-power microcontroller (MCU) for your next embedded design can be a confusing task when you compare claimed current consumption specifications in a myriad of data sheets provided by MCU vendors. In many cases, developers initially scan the first page of a data sheet as a reference point to gain basic information about an MCU, including peripherals, operating speed, package information, number of GPIOs and power characteristics. This approach works well to assess an MCU’s overall functionality, but it is not particularly useful when trying to gauge low-power characteristics.To get a broader view of an M CU’s true low-power operation, developers must take into consideration current consumption, state retention, wake-up time, wake-up sources and peripherals that are capable of operating while in low-power mode. Developers must compare a common operating mode to gain a balanced, apples-to-apples comparison among competing low-power MCUs. It is also important to take into consideration any additional functionality or peripherals that can reduce total system power and available evaluation tools that can make an engineer’s job easier.Microcontroller vendors will usually list the lowest power achievable on the first page of the data sheet. Although the device may be capable of achieving the specification in the data sheet, the actual operating mode may not be practical and useful in a real-world application. Some of the non-advertised features of the lowest power mode may include a very slow wake time, no state or RAM retention, or a reduced operating voltage range.To get around the variety of low-power specifications, developers must identify a common operating mode consisting of two sections: electrical specifications and low-power functionality.Comparing Electrical Specifications of MicrocontrollersThe electrical specifications are available in the data sheet, but determining which specifications are relevant may require some digging. Usually the electrical specifications are organized by vendor-specific power mode. This makes assessment slightly more difficult, as it requires knowledge and familiarity with the functionality of each power mode.In general, it is beneficial to define a set of operating conditions and then map them to a power mode. For example, the developer might define the following set of operating conditions:∙Sleep mode current consumption with state and RAM retentiono All other peripherals disabled∙Sleep mode current consumption with RTC running with state and RAM retentiono RTC enabled and running all other peripherals disabled.∙Wake time∙Supply voltage rangeOnce the operating conditions are clearly defined, it should be easy to determine the applicable vendor-specific power mode.Additional Low-Power FunctionalityThe second section, low-power functionality, is not as easy to locate in the vendor’s documentation and may be spread across the data sheet and reference manual. Examples of low-power functionality include: ∙Available wake sources∙How code resumes execution∙Peripherals capable of operating in sleep mode.Once the common operating mode has been clearly defined, developers can begin to examine the documentation in more detail.While going through this exercise of compiling data, keep in mind that there may be some MCU-specific features that can further optimize an application for ultra-low power. Optimizations may reduce bill of material (BOM) costs, provide longer product life or provide greater design flexibility. For example, an on-chip dc-dc converter can efficiently provide power to the system and decrease power consumption. This can enable the use of smaller batteries, which will decrease the overall BOM costs, or provide power budget flexibility. A variety of wake sources can provide design flexibility and allow the microcontroller to stay in the lowest power mode as long as possible, further reducing the average current consumption of the application.Allowing firmware to scale the internal supply voltage is another optimization knob available to the developer. If an MCU is operating at a slow frequency, it may be possible to decrease the supply voltage and save power. Selective clock gating allows hardware blocks to be disconnected from the active circuits, preventing inactive peripherals from consuming power. These types of features are not comprehended by supply current specifications that are commonly used to rank low-power MCUs, but are critical to achieving the lowest overall system power consumption.Reducing Complexity Using ToolsAs MCUs become more and more configurable to achieve the lowest power consumption, they also can become more complex. To cope with this increased complexity, developers should take a close look at the evaluation platforms available for an MCU and the overall ease of implementing a solution. For example, the development board and software tools used to program the MCU should be intuitive and easy-to-use. Hardware that is difficult to understand or use is not likely to lead to an easy firmware development process. From a firmware perspective, MCU vendors should supply firmware examples that can recreate specifications from the data sheet. If advertised current consumption specifications cannot be recreated on an evaluation platform, it is likely that it will be just as difficult (if not impossible) to configure the MCU to achieve these numbers on custom hardware. Giving customers a variety of code examples that can be used as a starting point for their code development can reduce time-to-market and help engineers learn to use a device.Graphical configuration tools can aid in development and help the developer gain a deeper understanding of an MCU. When developing low-power applications, it is helpful to know where the total consumed power is going. This information is useful because it highlights what aspect of a design needs to be further optimized and can also help the developer understand the overall architecture of the device. Ideally, low-power configuration tools could give tips on further reducing power as well as highlight any configuration errors that were detected throughout the configuration process. For example, the Power Estimator utility within Silicon Labs’ AppBuilder graphical configuration tool provides Power Tips that give configuration guidance and a power-budget pie chart showing how much power is consumed and which peripherals are consuming the power. As configuration changes are made, the pie chart automatically updates.Figure 1. Power Estimator Enables Developers to Optimize for Lowest Current Consumption To facilitate the microcontroller comparison process, the following table provides a list of common operating modes, as well as system-level optimizations and development tools available for Silicon Labs’32-bit SiM3L1xx MCUs based on the ARM® Cortex™-M3 core.SummaryEvaluating and selecting a microcontroller for a low-power application requires more than a quick scan of the first page of the data sheet. Determining which MCU provides the lowest overall system power requires developers to know the device’s supply current specifications, as well as any system-level optimizations that can reduce the overall supply current.Unfortunately, each MCU vendor specifies operating conditions differently and in some cases advertises a low-power number that is available in an unusable mode. Using a common operating mode to compare MCUs will prevent developers from being misled by vendor claims of ultra-low-power operation.Once the electrical characteristics of a device are understood and quantified, developers should take a look at the evaluation platform and software tools available. These considerations are crucial in getting an engineering team up and running quickly and should be included in the final microcontroller selection process.

The contents this article described include: basic concept of landscape openness and serene ranking, two criteria for landscape spatial perception evaluation, and three-level spatial patterns of landscape perception based on landscape openness and serene, which are indicated by 16 openness and serene inde_ and measurements. Taking the inde_ of M0 (comple_ity of terrain), M1 (fluctuation of field terrain), M2 (fluctuation of field terrain surface relief), M3 (visual fluctuation of viewshed), and M3’ (scene richness of viewshed) as the e_ample, the calculus of the mathematical formula of the inde_ and measure based on landscape digital terrain model (DTM) were demonstrated. One of the meaning and function of this principle, method and technique, initially proposed and created 30 years ago, is to provide a useful way for digitizing and evaluating the subjective-related perception of landscape through the translation of landscape objective environment information.Key words: landscape architecture; landscape analysis and evaluation; digitizing and evaluation of visual perception; landscape openness and serene ranking; digitize the sense of landscape beauty风景园林环境与感受的数字化是实现风景园林量化分析评价及其实践应用的关键技术，是风景客观环境与风景园林主观感受之间的桥梁，是实现风景园林分析评价的理性化途径。
