Description

Digital home's intellectualizing system based on the Zigbee technology

Technical field

It is digital home's intellectualizing system that means are utilized internet communication with the Zigbee technology that the utility model relates to a kind of, especially a kind of digital home's intellectualizing system based on the Zigbee technology.

Background technology

The structure of domestic and international existing digital home system is mainly based on traditional cable network technology, in the digital home system constructing ubiquity the wiring loaded down with trivial details, can't realize problems such as mobile access, long construction period, later maintenance difficulty, extensibility, these feature limits of wired system its application in the digital home system.Therefore, people begin one's study and introduce wireless technology and address these problems.

Radio network technique can satisfy the demands such as flexibility, reliability and convenience of user to home equipment control, home network well, has solved the expensive and inconvenient of wired system.

At present, in the research and development of wireless appliance networking and utilizing, mainly be Bluetooth technology and IEEE 802.11 technology, be speed but it emphasizes, and power consumption be but very high, uneconomical.

Zigbee be a kind of emerging closely, low complex degree, low-power consumption, low data rate, radio network technique cheaply, be mainly used near radio and connect.Compare with the wireless appliance networking technology of present use, main advantage is: message transmission rate is low, is absorbed in low transmission application, low in energy consumption, characteristics such as cost is low, network capacity is big, time delay is short, safety, effective range is little, working frequency range is flexible.Though and the zigBee mixed-media network modules mixed-media that present ZigBee technology is suitable for home appliances such as television set, refrigerator, roaster, washing machine, air-conditioning has come out, but realize with family's automatically-controlled door access control system, safety monitoring system and design InterWorking Equipment-digital home gateway of realizing Zigbee network and Internet, thereby to produce the technical products of the video monitoring of the remote monitoring of digital furniture and key position still be the problem that the insider tries hard to solve in realization.

Summary of the invention

The purpose of this utility model provides a kind of digital home's intellectualizing system based on the Zigbee technology.This system can satisfy interconnected with Internet, realizes with family's automatically-controlled door access control system, safety monitoring system and to the requirement of control in real time of tame electric appliance by digital home gateway.

For this reason, for solving this technical problem, the technical scheme that the utility model adopted is: the utility model relates to a kind of digital home's intellectualizing system based on the Zigbee technology, have three layers of physical communication interface, ground floor comprises the Internet, household appliances, mobile phone, PDA, computer is in interior communication interface, the second layer comprises gateway, router is in interior communication interface, the 3rd layer is included in family's automatically-controlled door access control system, safety monitoring system is in interior communication interface, wherein, be provided with Zigbee lattice network module in described first communication interface, be provided with interface module between the gateway in described Zigbee mixed-media network modules mixed-media and described second layer communication interface, between the described second layer and described three layers of communication interface, be provided with Zigbee lattice network module, and described each layer realizes that by the RF radio-frequency receiving-transmitting communication each other connects.

Compared to existing technology, especially with the wireless appliance networking technology of present use, the good effect that the utility model produced is: can realize the requirement that network capacity is big on the ground floor communication interface, can realize that on the second layer communication interface message transmission rate is low, be absorbed in that low transmission is used, low in energy consumption, requirement that time delay is short, can realize on the 3rd layer of communication interface that cost is low, safety, working frequency range requirement flexibly; Zigbee lattice network module gets involved between these three communication interfaces, can realize the requirement to the video monitoring of the remote monitoring of digital household appliances and household key position.
