Design of Refueling Control System with Multi-ControlTerminal Based on Network

This paper discusses a network-based refueling control system with multiple terminals that achieves the input and display of near-aircraft position, station, centralized console. The can achieve closed-loop flow, automatic fixed amount, collection environmental parameters, such as pipeline pressure, according to aircraft model. Moreover, dynamically parameter information process in real time on three terminals. To meet requirements functions real-time performance tasks, this study selected LPC2378 controller ARM core. uses µC/OS-II embedded operating software platform. special explosion-proof system, 485 bus was employed communicate unit (DCU) intrinsically safe contact stand station. communication adopts dual-redundant Ethernet full-duplex communication. avoid influence external equipment circuit, power isolation method adopted ensure stability system. After comprehensive debugging hardware software, we deem has good be applied engineering.
