智能家居安防

      ①智能家居安防系统是集信息技术、网络技术、传感技术、无线电技术、模糊控制技术等多种技术为一体的综合应用系统,是具有较强的技术性和前瞻性的新产品,

      ②通常,智能家居安防系统主要包括三大系统。

      ③第一是门禁系统。可靠安全的防盗门至关重要,它是家庭防护的第一道防线。门禁系统为主人提供坚固防范的同时,还提供了更多出入的方便。主人可以授权自己、家人、访客,通过密码、指纹、语音口令等智能识别方式方便地进出家门。

      ④第二是报警系统。报警系统由防盗报警系统、防火灾报警系统和防燃气泄漏报警系统等组成,它可以作为一种可靠且有效的方式让家庭能够避免外界侵入和自然因素引起的灾害。报警系统通过安装在室内外的各种传感器,将探测发出的信号最快地传递给相关人员。如烟雾火警探测器和可燃气泄漏探测器,它们在烟雾或可燃气达到一定的浓度时就会迅速发出警报以便用户知晓。

      ⑤第三是监控系统。监控系统是用于本地和远程了解特定区域情况,保留录像备查,起着威慑、监督、取证和管理作用的网络系统。监控系统具有实时监控功能,通过分布在室内的监视器、触摸屏等设备,可以监控住宅周边、门口、各个房间、室内通道等重点区域的实时情况。用户可通过手机随时随地查看家里的变化。系统还会自动将实时监控的影像通过硬盘录像功能录制下来,如果有盗贼闯入,就可以记录下盗贼的影像作为证据。

      ⑥此外,考虑到室内环境安全问题,环境监测系统也被划到安防这一块,顾名思义,环境监测系统主要是对室内环境进行监测的系统,包括甲醛探测仪、PM2.5探测器、二氧化碳探测器等。该系统的功能是实时对空气中某些有害物质的探测和对空气质量进行调节。

      ⑦智能家居安防系统是一个复杂的网络系统。各种智能防护设备通过信息通讯系统、网络系统彼此配合,协调工作,组成一个智能化的安防系统。它为我们享受高品质的智能居家生活提供了有力的保障。

阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项,并在答题卡上将该项涂黑。

    Have you ever fancied sailing around the world or buying a holiday home in the Caribbean? Well, before you get too excited, it may help to find out if you have what it takes to become a billionaire.   

    We've all heard stories of school drop-outs who have made their fortune. Do they tend to be university graduates or self-made successful people? Are they married or single?

    Thanks to a recent analysis of people in Forbes(福布斯)Top 100 Billionaires List, we can now find out what they have in common. We know what percentage wear glasses and even how many are bald!

    If you are deciding whether or not to go to university, it may help you to know that 76% of the richest people in the world have a degree. According to this study, of those 76%, 47% have a bachelor's degree, 23% have a master's and 6% have a doctorate. Don't lose hope if you aren't very academic, though. It's worth noting that many of those on the list did not pass all their exams with flying colors. Microsoft founder Bill Gates dropped out of Harvard University after two years of study. And Chinese business magnate Jack Ma, failed his university entrance exams three times before going on to complete his degree and make his millions.

    Another interesting trend is that the world's richest people are much more likely to be married - only 12% of billionaires are unmarried. Finally, the percentage of billionaires who are bald is quite high – so don't worry if you're losing your hair.
