针对运输飞机灭火瓶故障率高且使用单位缺乏地面充填设备的问题,提出了一套完整的飞机防灭火剂充填装置设计方案,并在完成样机制作后及时交付用户试用。简要说明了飞机防灭火系统的基本工作原理和防灭火剂充填的技术要求,着重介绍了防灭火剂充填装置气液回路系统的组成、功能和特点,并利用平板电脑、PLC等为核心设计了该装置的自动控制系统,给出了硬件系统和软件系统的实现方法。最后,通过试用验证了该装置的综合性、稳定性和可靠性。该设计方案有很高的实用价值,满足了用户的要求。
Aiming at the problem of high failure rate of transport aircraft fire extinguishing bottle and the lack of ground filling equipment for the use units, a complete set of design scheme of filling device for anti-fire extinguishing agent was put forward and delivered to users for trial after the prototype was completed. The basic working principle of aircraft fire extinguishing system and the technical requirements of fire extinguishing agent filling are briefly described. The composition, functions and features of the gas-liquid circuit system of fire extinguishing agent filling equipment are emphatically introduced. The design of the gas-liquid circuit system with tablet PC and PLC as the core The automatic control system of this device gives the realization of hardware system and software system. Finally, the comprehensiveness, stability and reliability of the device have been verified through trial. The design has a high practical value, to meet the user’s requirements.
