摘要
无线网络可以克服传统网络技术中有线传输介质带来的组网困难。根据现场控制需要,基于射频技术,设计了一种使用2.4GHz公用频率通道和具有主从星型拓扑结构的无线控制网络。主设备采用FPGA驱动射频模块,从设备采用单片机直接驱动射频模块。实验结果证明,该方案具有可行性。
Wireless communication could overcome weakness of conventional network. A wireless control network based on radio-frequency technology is designed to satisfy actual control needs. It consists of master and slave equipments, using 2.4GHz public frequency channel and star topology. The master equipment and slave equipment respectively uses FPGA and MCU to drive radio-frequency module. Experimental results show that the scheme is feasibility.
