Zigbee(IEEE 802.15.4)

Zigbee is IEEE 802.15.4 agreement pronoun. According to this agreement and the technology is a kind of short, low power dissipation of wireless communication technology. The name comes from the character of dance, due to the bee bee bee) by (flying and "hum" (zig) shaking wings "dancing" to and companion transfer pollen location position information, i.e. bees rely on such form a group of communication networks. Its characteristic is close, low complexity, self-organization, low power consumption, low data rate and low cost. Mainly suitable for automatic control and remote control field, may be inline with all sorts of equipment. In short, ZigBee is a cheap, low power close distance, wireless network communication technologies.

Zigbee origins

Zigbee, it is similar with bluetooth. Is a kind of burgeoning short-range wireless technology

This idea was put forward in 802.15 workgroup IEEE, so TG4 working group was established, and to establish a standard IEEE 802.15.4.

In 2002, was established. Zigbee Alliance

In 2004, zigbee V1.0 born. It is zigbee first norms. But due to launch hasty, there exist some mistake.

In 2006, launched in 2006. Zigbee, comparatively perfect

The end of 2007, zigbee PRO launched

Zigbee rock-bottom technology based on 802.15.4. IEEE

The physical and MAC layer directly cited IEEE 802.15.4

In the use process bluetooth technology, people found bluetooth technology although there are many advantages, but there are still many defects. For industrial, family automation control and industrial telemetry remote sector, bluetooth technology appear too complex, power, closer, networking too small, etc., and the industrial automation of wireless data communication needs is more and more intense, and, for industrial field, this kind of wireless data transmission must have been highly reliable, and can resist industrial field of various electromagnetic interference. Therefore, after people long-term endeavors, Zigbee agreement formally published in 2003. In addition, Zigbee used in it before the studied facing family network communication protocol Home RF Lite.

Long-term since, low price and low bit rate, short, low power wireless communication market have existed. Since the Bluetooth after appearing, ever let industrial control, household automatic control, toy manufacturers such as providers caper unceasingly,

But the price of Bluetooth stubbornly high severely affected these manufacturers use intention. Today, these industry attended IEEE802.15.4 group, be responsible for making ZigBee physical and media media access layer. IEEE802.15.4 norms is an economic and efficient, low-data-rate (< 250kbps), work in 2.4 GHz and 868/928MHz wireless technology used for personal area network and peer-to-peer network. It is ZigBee application layer and network layer protocols foundation. ZigBee is a kind of burgeoning close, low complexity, low power consumption, low data rate, low cost of wireless network technology, it is a cross between a bluetooth wireless markup technology and the technical proposal between. Mainly used for close wireless connections. Its basis 802.15.4 standard, in thousands of tiny sensor between mutual coordination realize communication. These sensors only need little energy to relay way through radio waves will data from a network node to another node, so their communication efficiency is very high.

Xbee/xbee - pro zigbee module

Based on the XBee/Ember chip XBeePRO module is a section of the built-in protocol stack ZigBee module, it through serial use AT command set and the API command set two ways to set module parameters, and through a serial port to realize the data transmission. In order to shorten the development cycle, users provides X - CTU (AT Zigbee Operator command) and two configuration software, can in a short time XBee/XBeePRO module familiar development.

Xbee - pro Zigbee Operator development kit

Aiming at the XBee/Ember chip XBeePRO development kit is a section based on XBee and XBeePRO module on the Zigbee development suite, through development kit can understand the use XBee/XBeePRO module development method, and simple use Zigbee technology, the system provides a set of sole XBee series module development application software Zigbee Operator, through Zigbee Operator, can will XBee/XBeePRO module of the function of perfection. Summary:

1. Working frequency for GHz ISM 2.4

2. XBee power output for 1 HaoWa (0 dBm) (up to 100 meters range)

3. XBeePRO power output for 60 HaoWa (18 dBm), 100 HaoWa EIRP (up to 1 mile range)

4. U.F l. RF connectors, SMA antenna, telescopic antenna can be chosen

5. Industry-specific temperature range (40-85 ° C)

6. In the us, Canada, Australia and Europe used extensively, and has been approved.

7. Support advanced network and low power consumption mode (support ZNET2.5 and Zigbee)

8. Support no.5 12bit AD (development board used 2 road)

9 and development kit matching manuals

10. Digi original X - CTU software, easy to use software to module configuration.

11. Zigbee Operator software, can use through this software to realize various complex function.
