基于ZigBee数字家庭智能终端装置 ZigBee smart terminal device based on digital home

技术领域 FIELD

本实用新型涉及一种家庭智能终端装置,尤其是一种基于ZigBee 数字家庭智能终端装置. 背景技术 The present invention relates to a home intelligent terminal device, in particular a ZigBee-based digital home intelligent terminal device. BACKGROUND OF THE INVENTION

在国际先进国家和地区,数字家庭产业已经成为了一种新兴产业发展趋势。 In advanced countries, the digital home industry has become a new industry trends. 日本、韩国、以及我国的台湾在数字家庭发展的较为迅速, 从全球数字家庭的发展看,韩国的研发是走在前面的,早在2000年, 韩国政府就启动了"因特网信息家电技术开发计划",最早的"数字家庭计划"方案也相继发表,作为全球互联网普及程度最高的国家, 韩国已将家庭网络摆在了首要地位。 Japan, South Korea and China's Taiwan in digital home development is more rapid, from the development of global digital home watching, Korea R & D is walking in front of, back in 2000, the Korean government started the "Internet information appliances technology development plan "earliest" digital home "program have also published, as the world's countries with the highest Internet penetration, South Korea has been placed in the home network primacy. 目前韩国的多数家庭已实现了家庭内部的互联共享,数字娱乐应用服务也火热的展开。 At present, most households in South Korea have implemented Internet sharing within the home, digital entertainment services are also hot start. 而作为智能家居技术非常发达的韩国来说,韩国政府更是表示了对智能家居的高度重视。 South Korea as smart home technology is developed, the more is the South Korean government attaches great importance to the smart home. 日本则主要强调能源的节省和环保问题,另外,自行开发具有本国自主知识产权的网络家电操作系统软件是日本数字家庭领域的一大特色。 Japan is the major emphasis on energy saving and environmental protection, in addition, has developed its own proprietary network operating system software appliances is a major feature of Japan's digital home.

英特尔、索尼、IBM、惠普等国际巨头早早开始了在数字家庭领域的战略布局,并且它们之间合纵连横,试图获取市场先机。 Intel, Sony, IBM, HP and other international giants started early strategic layout in the digital home, and vertical and horizontal alliances between them, trying to get market opportunities.

到2008年将有52%的美国家庭和47%的欧洲宽带家庭部署家庭网络;在亚太地区,家庭网络将实现与宽带家庭的数量同步增长。 By 2008 there will be 52 percent of US households and 47% of European broadband home deploy home networks; in the Asia-Pacific region, home networks will be achieved with the simultaneous increase in the number of broadband households. 从90年代初开始,因特网进入了全盛的发展时期,平均年增长率为 From the early 1990s, the heyday of the Internet has entered a period of development, with an average annual growth rate of

162%。 162%. 根据Forrester Research的研究,在美国大约有5千万个家里拥有超过一台计算机的家庭并且到2010年预计将达到7千5百万个。 According to Forrester Research, in the United States there are about 50 million home with more than one computer in the home and by 2010 is expected to reach 275 million. 随着计算机价格的下降,越来越多的家庭将拥有第二台和第三台计算机或膝上电脑,这将使家庭网络的需求增长。 With the decline in computer prices, more and more families will have a second and third computers or laptops, which will increase demand for home networks. 另一个趋势是各种能连接到互联网上的是新设备的大量涌现。 Another trend is the variety can be connected to the Internet is that large numbers of new equipment. 像智能电话、MP3播放器、 MP4播放器、游戏机这些能与网络连接的设备的需求同时也推动了家庭网络的需求。 Such as smart phones, MP3 players, MP4 players, game consoles, the demand for these devices can be connected to the network at the same time also contributed to the demand for home networks.

目前在这一领域存在着许多互不兼容的技术标准,包括CEBus、 ECH0NET、 KNX、 UPnP、 DLNA、 "e家佳"联盟标准、0SGi、 IHA、 UWB, FTTH等等。 Currently, there are many incompatible technical standards in this field, including CEBus, ECH0NET, KNX, UPnP, DLNA, "e home good" Union standards, 0SGi, IHA, UWB, FTTH and so on. 如何将这些标准统一成单一平台,开发能够被业界和消费者接受的增值服务,同时保持比较低的初始价格,将是"数字家庭计划"急需解决的问题。 How these standards into a single unified platform, the development of value-added services that can be accepted by the industry and consumers, while maintaining a relatively low initial price, will be "digital home" urgent problem.

据市场研究机构预测,ZigBee可在半径数十米的范围内实现最大传输速率为250Kb/秒的无线通信,该通信标准的通信速率与同样使用2.4GHz频带的无线LAN、蓝牙相比较慢,但它具有可以使用干电池等低功耗优势。 According to market research forecasting mechanism, ZigBee may be implemented within a radius of several tens of meters maximum transmission rate of wireless communication 250Kb / sec communication rate of the communication standard using the same 2.4GHz band wireless LAN, Bluetooth, compared to slow, but it can be used with a dry low-power advantages. 接入设备可达65535个,蓝牙接入设备为8个。 Access equipment up to 65 535, a Bluetooth access devices is eight. 因此被广泛应用在家电控制、屋外安防监控设备、楼宇管理、玩具等领域。 It is widely used in appliance control, security monitoring equipment outside the house, building management, toys and other fields. 预计到2010年,在全球范围内,该市场的规模将达到2亿个, 到2015年,则将增长到5亿个。 Estimated that by 2010, on a global scale, the size of the market will reach 200 million by 2015, it will increase to 500 million. 这一预言正在从ZigBee联盟及其成员近期的一系列活动和进展中得到验证。 This prediction is verified from a range of activities and progress of the ZigBee Alliance and its members in the near future. 美国TI公司、zilog公司、 韩国SK telecom公司、LG公司都有基于ZigBee技术在数字家庭的自动化,安全,家用电器和其他设备方面应用的报道。 American TI company, zilog, Korea SK telecom company, LG companies have reported based on ZigBee technology applications in the digital home automation, security, home appliances and other devices.

相对于现有数字家庭中的各种无线通信技术,ZigBee技术具有 With respect to the various wireless communication technologies conventional digital home, ZigBee technology

低数据速率和通信范围较小的特点,适合于承载数据流量较小的业务,主要应用领域包括数字家庭、工业控制、消费性电子设备、汽车自动化、农业自动化和医用设备控制等。 Small low data rate and communication range of features suitable for carrying data traffic small business, the main application areas including the digital home, industrial control, consumer electronics, automotive automation, agriculture automation and control, medical equipment.

ZigBee技术可以凭借简单便宜的方案,建构广阔而又稳定的无线网络,采用普通电池即可运作多年,能以低成本构建稳固的无线网状网络。 ZigBee technology can rely on simple and inexpensive solution to construct a broad and stable wireless network, using an ordinary battery can operate for many years, to build a robust wireless mesh network at a low cost. 生产商可以利用ZigBee这个标准化无线网络平台,设计简单、可靠、价格低廉又省电的各样产品。 Manufacturers can use this standardized ZigBee wireless network platform, designed to be simple, reliable, low cost and energy saving products of all kinds.

目前可用于组建家庭网络的技术主要包括以下3种:在家庭中铺设新线;利用已有的线路,无须铺设新线;釆用无线方式组网。 Currently available for setting up a home network technology includes the following three: the laying of new lines in the family; use of existing lines, without the laying of new lines; preclude the use of wireless networking. 国内大多数公司的产品都是采用传统的有线网络方式来构建数字家庭网络的。 Most products are domestic companies to build a digital home network using the traditional wired network approach. 其中上海五艾智能系统有限公司推出的智能住宅系统可通过电脑对住宅的门窗、温度、灯光及一切电子设备进行监控,还可以利用电话对家中的设备进行远程控制。 Where the Shanghai Five Ai Intelligent Systems Co., Ltd. launched the smart house system can be monitored by computer for residential windows and doors, temperature, lighting and all other electronic equipment, can also home remote control devices use the telephone. 深圳正星特科技有限公司一系列基于以太网的ST-100IP住宅智能化系统、ST-100IP视频点播系统、 ST-11远程抄表系统等。 Shenzhen is a series of Star Technology Co., Ltd. and other Ethernet-ST-100IP domestic intelligence system, ST-100IP video-on-demand systems, ST-11 remote meter reading system.

但是,以上产品仅局限于采用有线网络技术构建数字家庭,使用范围和产品特性都不能适应市场需求。 However, these products is limited to a wired network technology to build digital home, range and product characteristics can not meet the market demand.

即便是目前的"e家佳"(ITopHome)联盟推出了的整套家庭网络系统,但在推广中也受限制。 Even the current "e home good" (ITopHome) coalition launched a package of home network systems, but also in the promotion is limited. 原因是l、必须是联盟内的产品才可互联互通2、因为家庭网络采用802. ll协议,给众多终端产品制造商带来的无形中生产成本的增加,价格高,组网复杂、3、对不想更换现有家用电器的用户无法推动。 The reason is l, the product must be within the Union before interconnection 2, because the home network using 802. ll agreement, to increase the number of end-product manufacturers virtually brought production costs, high prices, complex networking, 3, users who do not want to replace the existing household appliances can not be driven.
