摘要
登机桥是机场用以连接候机厅与飞机之间的可移动升降的通道,智能化与无人化已经成为登机桥发展的必然趋势。在民航机场登机桥自动驾驶的设计过程中,需要对调平开关实现软控制。为了保证系统的可靠性与安全性,需要设计一种自动驾驶登机桥调平开关保护电路来避免异常情况对登机桥乃至飞机产生致命的损坏。针对这一问题,设计了一种基于译码器的调平开关保护电路,可以快速有效地解决人员误操作导致的异常情况。测试结果显示,本设计很好地解决了异常情况,且可以在人为操作的情况下,快速切换控制模式,具有很高的安全性与可靠性等特点。
The boarding bridge is a movable passage for the airport to connect the terminal with the aircraft.Intelligent and unmanned has become an inevitable trend in the development of the boarding bridge.In the design process of the automatic driving of the boarding bridge of the civil aviation airport,it is necessary to realize soft control of the leveling switch.In order to ensure the reliability and safety of the system,it is necessary to design an automatic driving boarding bridge leveling switch protection circuit to prevent the abnormal situation from causing fatal damage to the boarding bridge and even the aircraft.In response to this problem,a leveling switch protection circuit based on a decoder is designed,which can quickly and effectively solve the abnormal situation caused by personnel misoperation.The test results show that this design solves the abnormal situation very well,and can quickly switch the control mode under the condition of human operation,which has the characteristics of high safety and reliability.
