摘要
为打好蓝天保卫战,落实民航节能减排工作,提倡并推广在民用机场使用桥载设备代替飞机辅助动力系统,桥载设备的安全可靠控制亦能够有效保障飞机的稳定运行;文章基于DCS系统平台,利用虚拟DPU技术设计实现了一个机场桥载设备控制系统,减少了硬件DPU、I/O卡件的使用,降低了控制系统成本;系统利用工业级串口服务器作为中间设备与虚拟DPU进行数据通信,实现对桥载设备的数据采集和生产控制,同时利用DCS系统的控制算法实现了机场桥载设备的运行能效分析,为运维管理提供了有效技术支撑;控制系统的网络通讯负荷率不大于20%,虚拟DPU的平均负荷率测试不大于40%,整个系统的可利用率大于99%;该系统已在四川绵阳机场现场应用,取得良好效果,且各项指标满足生产需要,为虚拟DPU技术在工业环境中的应用提供参考。
In order to protect the blue sky and implement energy saving and emission reduction in civil aviation,we advocate and promote the use of bridging equipment instead of aircraft auxiliary power system in civil airports.The safe and reliable control of bridging equipment can also effectively guarantee the stable operation of aircraft.Based on DCS system platform,we design and implement a control system for airport bridge equipment by using virtual DPU technology,which reduces the use of hardware DPU and I/O cards and reduces the cost of the control system.The system uses industrial-grade serial port server as the intermediate equipment to carry out data communication with virtual DPU,and realizes the data acquisition and production control of the bridge equipment.At the same time,the control algorithm of DCS system realizes the operation energy efficiency analysis of the airport bridge equipment,which provides effective technical support for the operation and maintenance management.The network communication load rate of the control system is not more than 20%,the average load rate of the virtual DPU is not more than 40%,and the availability of the whole system is more than 99%.The system has been applied in Mianyang Airport,Sichuan Province,and achieved good results and the indicators meet the production needs,which provides a reference for the application of virtual DPU technology in industrial environment.
