Research On Metal Structures Monitoring System Of Large-scale Machinery And Equipment Based On WSN

With more and more widely use of Large-scale machinery and equipment, it's playing an increasingly important role in the national construction projects. As the production of machinery and equipment has a direct impact on the safe production and economic construction, the security issues of Large-scale machinery and equipment we need more attention. Need to use more convenient and effective methods detect the safety of machinery and equipment to improve equipment efficiency. A typical example is lifting equipment, by lifting quality, poor site conditions, working hours, have a significant effect on the life and work performance. Although the country has developed a variety of standards related to machinery and equipment, to assess the mechanical properties of the device also provides the specification, the National Security Administration has issued the relevant files, but the casualties caused by mechanical equipment often found to occur. Effective machinery and equipment metal structure detection methods, eliminating accident risks, direct guiding significance for the daily maintenance and upkeep.A Large-scale machinery and equipment crane structure remote monitoring system based on ZIGBEE technology were designed and developed in this paper. The system uses the zigbee network, automatic network nodes, data transmission. And complete high-precision dynamic load stress data acquisition and transmission, and monitoring real-time display of data.Improve the validity of the measurement system accuracy has an important effect in assessting and predicting the metal structure of the large-scale machinery and equipment efficiency and safety of life.Can not only improve the efficiency of monitoring, there are good economic and practicality. In this thesis, the actual use of objects and monitoring of project applications described below:First describes the developments and trends of the wireless sensor network, the introduction of domestic and foreign research related sensors and wireless network. And the wireless data transfer methods based on the ZIGBEE, were compared between varieties of wireless transmission. ZIGBEE transport protocol in the actual on the basis of understanding, to lay a theoretical foundation for the realization of data transmission method.Select power measurement method of stress testing followed by hardware circuit design, measurement principle used in the actual so can analysis the number of relationships. IIC communication used between the PS09and the CC2530chip, and routing node, the coordinator node procedures are described.Finally, on the basis of the system hardware and software design, designed the practical applications.
