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。
Aiming at the shortage of the existing aerostat pressure control system design and combining with the use environment of the aerostat, a pressure regulating control device based on dual redundant hot backup, embedded CPU, high-precision real-time data acquisition and processing is proposed. Program. First, the mathematical model of differential pressure of aerostat is established. Secondly, based on this model, the design of pressure regulating control system is designed, including the design of redundant pressure control system, the design of arbitration fusion emergency and the design of pressure automatic control. Finally, the air test of the tethered balloon with this kind of design shows that the control of the pressure system can fuse the status information of the sensor network according to the different working conditions of the balloon, independently select the entrance of the self-control program, and better control the balloon balloon pressure Conducted an effective regulation and control to ensure the safety of the balloon.
