In order to enhance the automatic level of civil airport refueling system, the principle and method of DCS (distributed control system) was applied to design and realize airport refueling automatic systems. According to the principle of "distributed control and centralized management", the system structure was divided into 3 layers: field equipments layer, direct control layer, and supervisory control and management layer. The main functions, the configuration of hardware, and the development of software, of each layer were summarized. The scheme has been successfully used in several airport refueling automatic systems. The practice indicates that these systems are steady, reliable, and have high automatic level.
