Abstract: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.
