摘　　要：针对目前箭载无线传感器网络数据可靠采集与能源消耗间的矛盾,在研究Powerlink工业以太网特点的基础上,设计了多路采集的低功耗箭载监控系统。该系统将Powerlink网络搭载在现场可编程门阵列(FPGA)硬件平台,通过修改硬件参数,将Microblaze软核重新配置并规划FPGA片上资源,实现数据高速传输;采用实时时钟芯片DS1306部署多个自定义触发中断作为主节点唤醒标志信号,在保证系统可靠性的情况下,实现系统功耗动态管理。搭建实验平台对监控系统进行测试。实验结果表明:系统数据采集无误码,平均通信周期450μs,最大偏移量仅为25μs,启用功耗管理模块后,系统功耗降低54.6%,在一定程度上,可以改善传统传感网络在箭载监控过程中的局限性。Aiming at the contradiction between reliable data collection and energy consumption in current rocket borne wireless sensor networks,a low-power consumption rocket-borne borne monitoring system with multi-channel collection is designed on the basis of study on the characteristics of the industrial Ethernet on the Powerlink.The system carries the Powerlink network on FPGA hardware platform.By modifying hardware parameters,reconfiguring the Microblaze software core and planning FPGA on-chip resources,high-speed data transmission can be achieved.Using the real-time clock chip DS1306,multiple custom trigger interrupts are deployed as the main node wake-up flag signals to achieve dynamic management of system power consumption while ensuring system reliability.Build an experimental platform to test the monitoring system.Experimental results show that the system data collection has no error code,with an average communication cycle of 450μs,the maximum offset is only 25μs.After using the power management module,the system power consumption is reduced by 54.6%,which can improve the limitations of traditional sensor networks in rocket-mounted monitoring to some extent.
