Design of Sink node of perception system of energy consumption for mine crane

针对采用有线传输方式难以实时监测起重机能耗的问题,提出了一种基于无线传感器网络的矿用起重机能耗感知系统Sink节点软硬件设计方案。该节点采用CC2530无线射频芯片实现起重机工作参数的采集和无线收发,采用ENC28J60以太网控制器将接收到的采样数据转换成以太网数据包,上传给后台监控中心;在分析uIP协议栈的数据通信流程与特点的基础上,详细阐述了uIP协议栈在CC2530芯片上的移植,以及Sink节点功能函数的编写。测试结果验证了该设计方案能够准确地实现TCP数据包的传输,满足矿用起重机能耗感知系统数据传输需求。

For difficulty of monitoring of energy consumption of crane by use of wired transmission, a hardware and software design scheme of Sink node of perception system of energy consumption for mine crane based on wireless sensor network were proposed. The node uses wireless radio frequency chip CC2530 to realize acquisition and wireless transmission of working parameters of the crane, uses Ethernet controller ENC28J60 to convert received sample data into Ethernet data packet, then uploads it to background monitoring center. Transplantation of ulP protocol stack in CC2530 chip and compiling of performance functions of the Sink node were described in details based on analysis of data communication flow and features of the uIP protocol stack. The test result verifies that the design scheme can realize transmission of TCP data packet accurately and meet requirement of data transmission of the perception system of energy consumption for mine crane.
