What can a smart home do?

5

Nowaday, the use of computer controlling allows the home to be operated in a variety of ways. Some of these will make it more convenient for people to live in (for example smart watch as mentioned in previous article). Here are a number of examples of what a smart house can do:

Call Control

The security alarm panel set to the hall also functions as an answering machine and can be used to dial into the house so thatyou can command it to do certain things. This system relies on a PIN number, similar to what is used in a banking machine, to ensure that only the owner can control the home. It has a series of voice prompts that guide the operations of the home.

– You can call the house and command it to close the curtains.

– If the user has been away from home for a few days and want to be sure that the house is warm when you return, you can call the house and turn the central heating on. This system can also be used to call you at work or via a mobile phone if someone rings the doorbell when you’re not at home:

  • Friends may call you when you’re not at home so that they know when you will be back in the house and can arrange visits.
  • People of services delivery may drop packets in the lobby. The security alarm will prevent them from entering farther into the house.

Integrated security

The security system of the house can be enhanced or improved because the security alarm is able to communicate with other devices in the house.

-When leaving the house, with only one key, you can sort the security alarm, closing any open window, and make sure that all doors are locked.

– If you are away from home for a few days, the security alarm may order the curtains opened or closed in the morning and evening and also to turn some of the lights on and off during the night.

How does the information pass around the house?

Smart homes have the ability to distribute information and commands as described above. There are a variety of ways that this can be achieved. Widely they were divided into two methods: wired and wireless. The wireless communication system involves the most advanced technologies that have great potential with many uses in smart homes. The wired system uses bus wiring. A bus is a dedicated wiring cabling system installed purely for the purposes of distributing information.

Typically a communications bus rely on a pair of wires unshielded (UTP) which is a cable with at least two insulated wires separated from one another but without the liner to prevent interference of radio waves. The most common form is the telephone cable. In the intelligent home, a better quality of cable is required, which is generally and regularly network cables category 5, which is used for computer networks in modern offices. The category 5 cable consists of four pairs of wires, potentially allows four sets of signals to be sent on the same cable. In homes developed by the Joseph Rowntree (JRF) Foundation, a variant on the bus wiring is also used which it is called binding energy, where it is used a (UTP) cable for communication and low-voltage DC power for the devices.

Power line communication

The power line is the use of existing power network to carry data signals in addition to the 240 volt source. The communication of the power line can be a very effective means for installations in homes and which may require very little rewiring. This is limited to a relatively narrow as a result of the British legal regulation of usable frequency band. This limited bandwidth makes it useful for relatively simple messages, such as on or off, rather than more complex, such as transmitting video signals. The use of infrared transmitters and receivers at home is more common.

The remote control units for audiovisual unit almost exclusively use infrared to communicate with your applications. Infrared can also be used for purposes of command and communications in the smart home. However, very few systems have been developed in practice as they require a clear line of sight between the transmitter and receiver.
