摘要
针对大功率电磁干扰环境下以及复杂烟雾条件下的排爆机器人作业时的通信控制问题,提出了一套集无线通信、红外通信、激光通信于一体的多手段综合无线通信系统。并对各通信方式采取了多项改善措施以提升通信效果:一是采用功耗低的2.4 GHz频段无线通信,以提高无线射频的抗干扰能力;二是使用大功率红外发射管设计了大功率红外发射电路,利用反射镜与凸透镜凝聚红外光束,在接收端使用多接收器旋转阵列的方式多方向采集信号并利用遮光罩屏蔽杂散光线,从而提升红外通信距离;三是利用视频标注的方式解决激光通信对准的难题。通过试验验证了所设计电路良好的通信效果,达到了设计目标,并为类似的工程项目提供了参考。
In order to achieve communication control for anti-explosion robot in strong electromagnetic interference and envi- ronment and complex smoke condition, this paper proposes a set of wireless communication, infrared communication and laser com- munication in an integrated wireless communication systems. To enhance communication effectiveness, improvement measures are implemented. First, using the 2.4 GHz band radio frequency wireless communication to improve the anti-jamming capability. Second, using high-power infrared tube designed a high-power infrared transmitter circuit, using mirror and convex lens focus light beam, using photodiode array to increase the reception range and using lens hood to avoid stray light, thus infrared communication distance has been increased dramatically. Third, using video to solve aiming problem of laser communication. Experiments verifies the communication effect of the designed circuit, reaching the original design goals. Also it can provide a reference for similar projects.
