Artillery Real-time Monitoring Wireless Sensor Network Systems Research

Wireless sensor networks as a new smart network has a wide range of applications in many areas. State information needs to of a traction artillery positions traction establishing wireless sensor networks, some of the key technology and reliability, security research, and ultimately to establish a network to complete the data transmission system model.First, based on wireless sensor network design principles, a database-centric model of real-time data transmission system has been established.Second, by studying the impact of the wireless communication module data reliability factors, the proposed distance estimation model, more popular CC2533RF communication module based on ZigBee technology analysis of differential signal to a single-ended signal balun circuit, and use the ADS simulation and put forward the theory of value. According to the experiment, the actual match values of the circuit have been obtained; Study the key technology in the design of the hardware circuit.Again, the analysis of Z-Stack protocol stack workflow design process; focusing on analysis of linear block coding and elliptic curve encryption algorithm, and applied to the system, the use of third-party communication protocol used to ensure the safety and reliability of the communication transmission; research PC control software and lower machine nodes serial communication control program implementation.Finally, the establishment of the laboratory data transmission model, the security of data transmission temperature, weather, wind speed and direction, as well as ambient light module.In this paper, the analysis and design of hardware and software ZigBee technology, wireless sensor network system based on the real-time monitoring of database control oriented, experimental results prove that this design idea is feasible.
