摘要：
为了建立传感器节点和远端上位控制机之间的通信链路,利用无线传感器网络技术,设计实现了无线传感器网络数据转发器的硬件电路。数据转发器由工控机、无线通信模块以及电源管理模块三部分组成。系统能源主要来自于太阳能蓄电池,为了达到无线传感器网络的低功耗要求,数据转发器采用休眠任务唤醒模式。实际应用表明,此系统具备低功耗、能量自给、可远距离控制的特点,具有广阔的应用前景。

Abstract: Utilizing the advantages of wireless sensor network, the hardware circuit of information repeater in WSN (Wireless Sensor Networks) was designed and implemented in order to establish the communication link between the sensor nodes and remote control computer. The information retransmission device mainly consisted of industrial control computer, wireless communication module and power management module. The energy of this system mostly came from lead acid accumulator charged by solar energy. System design scheme supporting sleep mode and waken by task mode was proposed to minimizing the amount of energy consumption which was required by WSN. The practical application of this system shows that the characteristics of low power consumption, energy self-supplying, remote control stretch its application prospects.
