【 Weak current College 】 interpretation of smart home new Protocol

Trace this entire broadband device in the past, all associated with the automation. On the WiFi, before the Internet before that time, CEBus and LonWorks X10. On the smart home, those are ever popular too.

But the Internet and related technologies from the 1990s into the new millennium has become the focus of attention. Today, home automation, a whole batch of new technological and industrial innovation is attracting people's attention, especially lighting control.

Therefore, such as WiFi, automation protocol and broadband technology? the former must be low-cost (low enough to support the lighting switches and thermostats) and low-energy (you hope to replace the one you security sensor batteries?). In General, technology will increase at least 5 to 10 dollars in equipment costs.

Today's noteworthy new automation technology "two-way", means that sends and receives commands can be confirmed. For example, a key to the dimmer "open" command until the dimmer to confirm receipt of this instruction, the lights are actually open. Press to display the immediate feedback, that is, through the Green LED to indicate the outside light is open. Former unidirectional Protocol cannot display a set of devices on/tube State of the real information.

The new agreement
In the past two years, emerged in a large number of standard and private technology provider. The new agreement is not only for lighting control and automation products bring a perfect tool, but also gives us insight into the ever since the 1980s X10 inception and then not seen before.

Zigbee and Z-Wave new wireless technology, using grid technology — each port also equipped with a sink and a transmission device, in the most effective manner from one port to another port to spread across the entire device. In your home has more port, this technique will work.

Zigbee is a group for commercial/industrial control technology provider manifest, they have, Invensys, Motorola, MitsubishiandPhilips. This technology is an industry standard, IEEE802.15.4.

Zensys Z-wave is a product of the company in Copenhagen in 1999 as the home automation market, creating a RF special programmes.

At that time these two technologies are almost at the same time-to-market, was smart home Z-Wave cater to the needs of the market, so it is in this area there is a good base. Especially Z-Wave attracted most of the market, such as the famous brand Sylvania, Intermatic, and recent Leviton WqyneDalton.

Zigbee's followers were also in the commercial/industrial areas, but most important, because this technology come together at home business system of the company are: AMX, Crestron and Control4, Vantage.

The above describes the wireless technology, but don't overlook a home use AC power to transfer information back and forth the power line technology. The most formidable is the UPB (universal Powerline bus) from the PCS (power control system) production. PCS is a company in the automation area is known as a lighting control, which led the company from a X10 unknown power line technology development to have two-way communication and have a good credit rating in perfect agreement.

The development of the UPB PCS increased experience, but it is important to note that the noise from the wire. When MD manufacturers are the technology used in products of Central audio system, the wire is connected to the same UPB loud noise.

Several accepted the UPB agreements, mostly of the manufacturers of lighting control. This technology has been in late 2005, HAI Revolution (handy) (mass market in the United States on the most popular security/automation system manufacturer), beginning in its control panel support this technology, but also in the light switch, dimmer and other parts use the UPB.

Finally, Insteon, home control in the field of the new agreement introduced a RF/PLC interactive, home of wireless or wired electrical installations can communicate without the need for a variety of lines and connectors. This technique was invented by the SmartHome, this is a long-term commitment to the production and marketing of intelligent home company.

The receiver of this technology is the first brand, their production FirstAlert smoke detectors using Insteon can interconnect, and compatible with the light switch. A smoke alarm makes the Interior light quickly open, outdoor lights flashing.

This is just in the United States domestic market momentum. Echelon LonWorks based on the invention of PLC technology has been built in the United States in the field of public commercial success and to the consumers in Europe and Asia. The company has recently reduced the technology costs and productivity several new products in the hope of attracting up United States domestic market's attention. And a company Yitran, Israel by LG Electronics emplaced home control technology, hoping to break into the United States market. Finally, the most famous HomePlugConsortium Powerline broadband network scenario, exit at the end of 2005 a PLC programmes — called HomePlugCommand & Control or HPCC — designed for low interest rates and low-cost home control developed.
