机场航油ESD系统需要及时准确采集现场紧急停车信号,方能立即停止相关保障系统(如飞机加油系统、航油管线转输油系统)运行,切断系统动力源。对于那些新建机场而言,航油ESD系统对紧停信号的采集方案大多设计为传统的布线和按钮结合的方式,它们与管网敷设时一并敷设。但由于航油库站之间的距离一般较远,该方案实施中投资较大且由于管线所处环境的特殊性,在后期维护/维修难度往往难度较大。为此,建立一个以各库站为基点实现各基点之间信息准确及时交换的通讯传输系统,是后期航油ESD系统设计的新思路。本文结合武汉机场航油ESD系统,对无线数字传输技术的应用进行了论述。
Airport aviation oil ESD system needs timely and accurate acquisition of on-site emergency stop signals before it can immediately stop the operation of the relevant support system (such as aircraft refueling system and jet fuel pipeline transfer oil system) and cut off the system power source. For those newly built airports, the fuel-air ESD system’s acquisition of emergency stop signals is mostly designed as a combination of conventional cabling and pushbuttons, which are laid alongside the pipe laying. However, due to the relatively long distance between the depot terminals, the investment in the implementation of the program is large and the difficulty of maintenance / repair in the latter stage is often difficult due to the particularity of the environment in which the pipeline is located. For this reason, establishing a communication transmission system which realizes accurate and timely exchange of information among the base stations with each depot as a base point is a new idea for the design of the aviation fuel ESD system in the later period. In this paper, Wuhan Airport Aviation Oil ESD System, the application of wireless digital transmission technology are discussed.
