| 为提高高炉炉缸温度场监控系统的数据传输可靠性和稳定性，降低温度场监控系统的建设成本和运行维护成本，提出了一种基于网状无线网络的高炉炉缸温度场无线监控系统。该系统的数据采集节点安装在高炉炉缸外壁，将热电偶模拟信号转换为数字信号，大大缩短了热电偶模拟信号的传输距离，减少了外界干扰，再通过网状无线网络将温度数据传输至监控中心，进行分析建模和高炉炉缸状态监控。网状无线数据传输网络则是基于IEEE80211构建，并基于优化链路状态路由协议设计了一种双路径备份的自适应路由协议和主备路由的自适应切换机制。基于OpenWRT开源平台搭建了原型系统，在莱芜钢铁厂某型高炉进行了安装测试，能够长时间连续稳定运行，满足高炉炉缸温度场监控的需要。 |

| In order to improve the reliability and stability of data transmission of the temperature field monitoring system of blast furnace hearth, and reduce the construction cost and maintenance cost, a wireless temperature monitoring system for blast furnaces based on wireless mesh network (WMN) is proposed. The data acquisition node is installed on the outside wall of the blast furnace hearth, which converts the analog signal of the thermocouple into digital signal, greatly shortens the transmission distance of the analog signal of the thermocouple and reduces the external interference. Then the temperature data is transmitted to the monitoring center through the mesh wireless network for analysis modeling and blast furnace hearth condition monitoring. The mesh wireless data transmission network is constructed based on IEEE80211, and based on the optimized link state routing protocol, a dual path backup adaptive routing protocol and an adaptive handoff mechanism for primary and alternate routing are designed. Finally, based on OpenWRT open source platform, a prototype system is built and installed in a blast furnace in Laiwu Iron and Steel works. The system has been put into a long period of continuous and stable operation, which can meet the needs of blast furnace hearth temperature field monitoring. |
