MATEC Web of Conferences
ZigBee is a recent rise of wireless network technology, with low-rate, low cost, low power, network capacity and other characteristics, to organize their own network, and network recovery ability, very suitable for wireless sensor networks. In this paper, the industrial production environment, systematic study of the ZigBee technology, video compression technology, as well as data communication principle, the development of the industrial video monitoring and control system based on ZigBee

XQUHVWULFWHG XVH Article available at MATEC Web of Conferences technology; its powerful features make it the world's communications major modulation techniques. World War II accelerated the development of manufacturing and micro technology, and has been used in a large number of one-way and two-way radio communication systems and television systems. With the advancement of technology, the development, wireless communication technology has been extended too many fields such as business, agriculture, industry, etc., and the depth and breadth of applications evolving. ZigBee is a wireless network in recent years, the rise of communications technology, the technology alliance by British Invensys, Japan's Mitsubishi Electric, Motorola USA, the Netherlands, Philips Semiconductors and other companies in the development of a network, security and application software protocol layer, cost, power 01073-p.2 consumption, speed, complexity is relatively low, when the word is used to notify the pollen from the honey bees companion way location, is a simple, effective "Wireless Communications" in the form of. ZigBee technology is mainly used in short-distance data transmission between a variety of electronic devices, the lower its data transfer rate, and therefore suitable for industrial production environments wireless transmission of video data. Its main features are as follows has several areas: (1) The rate is low. ZigBee network in all the different bands work data transfer rates are at a low level, but also for different working frequencies corresponding rate is adjusted, so that work more in line with the principle of energy distribution. (2)Low power Because the transmission rate is low, the transmission power is only 1mW, and the use of sleep mode (when required data is received, only wake up by a network of "coordination" on them), so the ZigBee technology is very low power consumption, for energy security network to run a small, usually two AA batteries can support up to two years of operation of the network. (3)Low cost Compared to other short-range communication technology, ZigBee technology research and development costs low, because of its simple design protocol stack. Moreover, program development is also very convenient; eight microprocessors will be able to meet the needs of ordinary network. With the application and development of the product, is expected to further reduce costs. (4) Reliable data transmission. Using CSMA-CA (Carrier Sense Multiple Access-Collision Avoidance) mechanism to avoid a collision, and dedicated time to leave gaps for the fixed-band communications to provide protection, but also the establishment of independent network, data communication between nodes in the network have robust path transmission security, because the transmission path is not fixed, the flexibility to choose the best communication path through a router. (5)Short delay for latency applications optimized data communication with a relatively short delay and a short wake-up delay. (6)The network capacity ZigBee network can be employed, such as a star, the number of state and mesh network structure, can form large networks with a hierarchical network structure. (7)Network security ZigBee technology uses a common encryption algorithms, and provides a complete data packet check function (available on the quality of data packet inspection, such as redundancy and integrity), thus ZigBee network has very good security.
