home. For example, on a hot, sunny day, weather sensors can activate blind and drapery controls to shade your home, and ensure that your garden receives adequate irrigation at the right time of day. Motion and occupancy sensors can activate heat and lighting controls 沈陽航空 航天大學(xué) 畢業(yè)設(shè)計(jì)(論文) 外文 翻譯 —— 原文 5 as you enter and exit rooms. Today’s new smart IR sensors represent a union of two rapidly evolving sciences that bine IR temperature measurement with highspeed digital technologies usually associated with the puter. These instruments are called smart sensors because they incorporate microprocessors programmed to act as transceivers for bidirectional, serial munications between sensors on the manufacturing floor and puters in the control room (see Photo 1). And because the circuitry is smaller, the sensors are smaller, simplifying installation in tight or awkward areas. Integrating smart sensors into new or existing process control systems offers an immediate advantage to process control engineers in terms of providing a new level of sophistication in temperature monitoring and control. When you leave for work in the morning, your house could check for and turn off unnecessary energy consumers such as radios, TVs, stoves and irons (a nice safety feature). On your way home, you could use your cell phone or puter to change the temperature in your home, turn on lights, turn on the radiant heat in your bathroom floor and fill the bathtub to just the right level for a nice long soak. Appliances: From toasters to fridges to picture frames, the possibilities for working puterized household appliances are limited only by your imagination and budget. Your refrigerator can keep track of food expiration dates and act as a family message center via a builtin screen. Coffee makers and other small appliances (such as toasters) can be activated remotely or as part of a sequence of events. You can even imitate Bill Gates and install framed electronic artwork that changes depending on the preference of the person who enters a room, or purchase Interconnected picture frames that retrieve images from a gallery supplied by your friends and family for a constantly updated family portrait wall. The key to making your home more fortable, enjoyable and safe through home automation is to follow three essential steps: ? Plan: Discuss automation needs and wants with your family members so you can plan ahead. Take into consideration your home39。s television and videogame habits, when you39。s various electronic systems. These include: Entertainment: You may have been impressed by a friend39。t interfere with one another. Smart home technology may also enable you to dial in via a phone line to control specific home operating systems and/or be preset to dial out to a monitoring service in the case of a fire or breakin. While the possibilities for home automation are only limited by your imagination, the choices facing the average homeowner may seem daunting. The good news is that you do not need to bee a technological expert in order to enhance your home39。s existing electrical lines to transmit data. They are relatively easy to set up and operate but carry the risk of power surges, and an unencrypted household work may be accessible to neighbors sharing the same transformer. ? Phoneline works use a home39。s smart home automatically regulates heat, air and light, distributes audio and video around the house, controls access to your home and can even remind you to exercise!
