[Abstract]:ZigBee wireless communication technology is an important way of information communication. As one of the most popular research technologies in the 21st century, wireless communication technology plays an increasingly important role in human society. Wireless communication technology has been widely used in various fields of work, management, communication and education. The development of wireless communication technology has improved the quality of life of people, thus continuously promoting the development and progress of society. As a new short-range wireless communication technology, ZigBee technology has low power consumption and low data transmission rate. Since the advent of ZigBee technology, more and more researchers and enterprises have paid more and more attention to it, especially after the establishment of the ZigBee alliance, which has pushed the development of ZigBee technology to a new height. Today, ZigBee technology has been widely used in the fields of industrial control, smart home and consumer electronics. European and American countries have introduced consumer ZigBee products. Compared with foreign countries, ZigBee technology started late in our country, and has not been paid much attention by researchers and enterprises until recent years. However, the domestic ZigBee technology is developing rapidly, drawing on the mature ZigBee technology achievements and experiences of foreign countries. Attracting more and more universities and enterprises to join in the research of ZigBee technology, ZigBee technology has become one of the research hotspots in domestic wireless communication technology. Firstly, this paper introduces the concept of ZigBee technology, domestic and international research status and the significance of this topic, and deeply studies the specific framework and working principle of ZigBee protocol stack, including physical layer, media control access layer, network layer and application layer. Secondly, the types of devices and topology used in ZigBee network are introduced in detail, and the characteristics of them are studied deeply, and several existing ZigBee wireless clock synchronization algorithms are studied. Their basic working principles and advantages and disadvantages are analyzed. According to these ZigBee clock synchronization algorithms, a fusion clock synchronization algorithm based on TPSN and DMTS is proposed, and the basic principle of its implementation is introduced in detail. Thirdly, the overall structure of the wireless fire monitoring system is designed, and the hardware and software of smoke alarm node, acousto-optic alarm node and manual alarm node are studied and designed. The anti-electromagnetic interference (EMI) measures in the hardware design of the terminal node equipment in the wireless sensor network are studied carefully. Finally, the hardware platform and software platform of ZigBee wireless fire monitoring system are described in detail, and the functions of smoke alarm node, acousto-optic alarm node and manual alarm button node are tested. Performance test and life test. Through the NS2 network simulation platform, the designed ZigBee fusion clock synchronization algorithm is simulated and compared with other clock synchronization algorithms. Through the installation of the laboratory, the network becomes a complete fire alarm experimental system, and the low power consumption, stability and reliability of the whole system are tested.
