摘要
针对无线传感网络的草原气象自动监测系统硬件中的射频模块、系统感知模块、能量模块以及系统处理模块进行设计与选型,并采用直接序列的扩频技术,实现短距离的无线监测;在节点初始位置中添加相应的传感器软件,使代码能够有效整合到系统之中。经过分析不同字节的意义,对数据传输协议进行修改,并将寄存器数据值转换为真实数据值,方便客户查看。通过实验验证该系统的合理性,并得出实验结论。实验结果表明,该系统具有监测精确、速度快、时间短等优势,有利于牧区的生产。
For the automatic monitoring system of grassland weather,the design and model selection are performed for the RF module,system perception module,energy module and system processing module of the system hardware. The spread spectrum technology of direct sequence is used to realize the short-distance wireless monitoring for the modules. The corresponding sensor software is added into the initial position of the node to integrate the code into the system effectively. By analyzing the meaning of different bytes,the data transfer protocol is modified and the register data value is converted into the real data value for customer convenient viewing. The rationality of the system is verified with experiment,and the experimental conclusion is obtained. The experimental results show that the system has the advantages of accurate monitoring,fast monitoring speed and short time,and benefits the production of pasturing area.
