In order to realize his smart mansion, Bill Gates laid a 84-kilometer cable and connected all the electrical equipment in the house into a home network , costing 530 million US dollars. This money is enough to buy a medium-sized listed company. But nowadays, to build a smart mansion like Bill Gates' "House of the Future", perhaps it is not necessary to lay 84 kilometers of cable so much. With the development of wireless smart home , smart home has gradually got rid of centralized wiring. The drawbacks. After several years of market testing, the weakness of wired smart homes is unobstructed, that is, through the wall wiring, destroying the wall, the line is buried in the wall, the system wants to upgrade and update, it is more difficult than the sky, especially the diagnosis and failure during maintenance is also very Difficult, greatly reducing the consumer's pleasure of use. The trend of wireless smart homes to lead the market has been widely recognized by the industry. Currently, wireless technologies on the market mainly include Bluetooth technology, radio frequency technology and ZigBee technology . The emergence of Bluetooth technology makes short-range wireless communication possible, but its complex protocols, high power consumption, and high cost are not suitable for industrial control and home networks that require low cost and low power consumption. In particular, the biggest obstacle of Bluetooth is that the transmission range is limited. The general effective range is about 10 meters. The problems of weak anti-interference ability and information security are also the main factors that restrict its further development and large-scale application. Radio frequency technology transmits and receives data through the air, and uses radio waves to transmit data signals, which is relatively susceptible to external interference. The data packet can be detected or received by the outside world during the transmission process. Information security is a hidden danger. Although the data can be transmitted after being encrypted, if there are enough data packets, the hacker may still be cracked. ZigBee technology is a two-way wireless communication technology with low cost, low complexity, low power consumption, high security and short-distance transmission. It has the characteristics of strong scalability and can be embedded in various home devices. This is not possible with Bluetooth, WIFI, etc. of. ZigBee is an internationally popular wireless communication technology. It can access up to 65,000 ports per network port. It can be used in a wide range of applications. The POLYHOME smart home system developed by Beijing Boli Hengchang Technology will be used as a domestic The technology is applied to the representative enterprises of smart homes. While possessing all the advantages of ZigBee technology, POLYHOME has also solved the world problem through independent technology research and development - "Zigbee single fire power-taking technology", which can be realized only by one fire line. The smart home takes power and completely realizes 100% wireless smart home system.
