These systems allow the use of existing electrical wiring in homes , buildings and homes for home control .
The driver in this case consists of a microprocessor executive , relay and modem signal decoding flowing in the mains 230V .
An example of such a solution may be the standard X10 .
There are many other solutions based on this method of data transmission between devices .
Advantages and disadvantages of automation systems based on the data transmission through power lines: - The high price of the system due to the need for architecture: a modem device + 230
- A small number of devices depends on the standard (256) limiting the number of points controlled
- No encryption , protocols to enable the neighborhood of various installations of this type next to each other . Several working side by side installation interferes with and limits the number of available addresses to use . In addition, the possibility of simple interference with neighboring installations .
- Large interference effects that can completely immobilize the home control system
- An easy way to sabotage the plant through the grid disturbance by neighbors .
- lack of resistance to control the system from malicious hackers outside the neighborhood .
- Restricting the use of home away from other buildings with a well filtered power connector to prevent hacking into the system and its disruption
- The possibility of interference with the automation system or hack into it by example . connect to it from external 230V power outlets .
- The possibility of fire or serious damage due to direct connection to the mains 230V
- Installation requires companies with electrical powers and high technical expertise
- No possibility of amateur use of such transmission in accordance with the law due to the direct connection of equipment to the power grid and the need to comply with the standards and controls of approval .
- Transmission speed is the slowest compared to all other methods of communication between the automation systems of the building which is " bottleneck " system
- Much of this type of transmission collision data transmission especially in the presence of interference , large number of devices , different systems working side by side
- Limiting the use for simple automation lighting control , dimming , on / off 230V outlets and equipment (manual and semi-automatic)
- Inability to implement complex algorithms and complex home control
- The installation may be completely useless even after locating a small manufacturing plant in the area or other source of power grid disturbances
- High risk and lack of resistance to surges and lightning network , can damage the entire plant (all control modules at a time)
