摘要
针对目前提出的高灵敏度无线传感网络射频前端控制系统控制信号接收有效率低、控制强度差,设计了一种新的高灵敏度无线传感网络射频前端控制系统。前端控制系统的硬件区域由CPCI总线接口、射频开关控制器、RS 485总线、嵌入式微处理器、芯片、电源、异步通信装置、板卡构成,通过无线通信、无线传感、控制三步实现软件前端控制。实验结果表明,高灵敏度无线传感网络射频前端控制系统能够有效提高信号接收有效率,增强控制强度。
Since the currently proposed RF front-end control system for high-sensitivity wireless sensor network has low reception validity of control signal and poor control intensity,a new RF front-end control system for high-sensitivity wireless sensor network is designed.The hardware area of the front-end control system consists of CPCI(compact peripheral component interconnect)bus interface,RF switch controller,RS 485 bus,embedded microprocessor,chip,power supply,asynchronous communication device and board card,while the three steps of wireless communication,wireless sensing and control are used to achieve the software front-end control.The experimental results show that the RF front-end control system for high-sensitivity wireless sensor network can effectively increase the validity of signal reception and strengthen the intensity of control.
