摘　　要：针对现有浮空器压力控制系统设计的不足,结合浮空器的使用环境,提出了一种基于双机冗余热备份、嵌入式CPU、高精度实时数据采集与处理的压力调节控制装置解决方案。首先建立了浮空器的压差数学模型;接着,以该模型为基础,进行压力调节控制系统设计,包括多余度压力控制系统设计、仲裁融合应急处理设计、压力自控设计。最后,采用该种设计的系留气球的空中试验结果表明,该压力系统控制能够根据气球所处不同的工作状态,融合传感网络状态信息,自主选择自控程序入口,较好的对气球气囊压力进行了有效调节与控制,保证了气球的安全。To solve the problems in the existing pressure control system of aerostat ,the corresponding pressure con‐trol solution is put forward in consideration of the analysis of mathematical model about the air bag super pressure effects due to the variations of height and temperature based on dual‐computer hot redundancy ,embedded CPU , high‐precision real‐time data collecting and processing ,as well as the operation environment of the aerostat .Firstly the difference model is built .Then based on the model ,the pressure integrated system is designed ,including the design of redundancy pressure integrated control system ,the design of arbitrate amalgamation lash‐up operation and the design of pressure auto‐control .Lastly ,the results of aerostat air test which utilize this design show that the pressure integrated control system could introject the status messages of sensor net ,auto choose the entrance of auto control program according to the different operation status ,and the pressure of aerostat cell is adjusted and controlled effectively which assure the safety of aerostat .
