基于ZigBee与CAN总线技术的井下无线通信系统设计

摘要

针对矿山井下的特殊环境和对井下无线通信系统的实际需求,提出了基于ZigBee和CAN总线技术的无线通信系统,通信基站和终端之间应用ZigBee技术,系统总线采用CAN总线.介绍了井下无线通信系统系统的组成和工作原理,给出了总体结构图,对硬件的功能模块进行了较详细的阐述,系统的创新点是把ZigBee和CAN总线技术应用到井下无线通信系统.系统在功能和性能方面满足了矿山井下无线通信系统的需求,实际证明该系统具有良好的可靠性和抗干扰性性,能较好的进行井下无线通信.%A underground mine wire[ess communication system based on Zigbee and CAN bus technology is proposed according to the actual demand of special environment for the underground mine and the underground wireless communication system.The composition and working pronciple of the underground mine wireless communication system is introduced. The overall structure diagram of the system presented. Zigbbee technology is adopted for the communication between base station and terminals. and CAN is used for system bus. The function modules of hardware are elaborated. This system features and performance met the needs of the underground mine wireless communication system. The experiment results show that the system has excellent reliability and anti-jamming.
