Wireless Location Algorithm Optimization And Field Perception Based On Zigbee Technology

Environment awareness and wireless positioning system for special production disaster environment. In this kind of scenes, dangerous coefficient is high, natural condition is complex, personnel intervention meets difficulty, second destruction is serious, which urgently needs a set of automatic perception and the localization equipment. To investigate the scene, guarantee the rescue personnel security, this paper mainly studies a variety of advanced on-site sensing means, proposing a wireless localization algorithm based on ZigBee protocol to realize wireless remote monitoring function.This paper firstly designs the hardware part of the system. Selecting CC2530 radio frequency of TI to emit and receive data, using DS18B20 type temperature sensor, CA-YD-186 type low frequency vibration sensor,K7 model microphone and Sound Detector voice identifier and achieving a single power supply circuit to modularly design power supply.Then the wireless location algorithm is optimized. The one-dimensional ranging algorithm combined with genetic algorithm, the two positioning algorithm is with the location algorithm and non location algorithm advantages, which greatly improves the accuracy of the algorithm, while reducing the time complexity, improving the efficiency of the algorithm.Finally, the software part of field perception system is developed.The lower machine, transplanted the core code of temperature sensor chip DS18B20, combined with the wireless communication network ZigBee module. The MCU can complete the scene perception, information processing, primary instruction and accepting the sensing results function;the PC side, man-machine interface is designed to realize the graphical display of data.This paper has completed the optimization of wireless location algorithm, design and implementation of hardware and software of the field sensing .system. The accuracy of the algor:ithm and time complexity are better than the classical algorithm, the system of promotion, has strong guiding significance for other areas of engineering and technology.
