指挥控制系统是航天着陆试验场不可或缺的一部分,完成试验指挥、控制、管理、视频监控、数据分析与处理、故障判别、仿真、授时、通信等功能。文章所介绍的某航天着陆试验场指挥控制系统,由时统子系统、通信子系统、语音调度子系统、视频监控子系统、大屏幕投影显示子系统、数据处理与存储子系统、指令发控台、指显工作站、软件等组成。系统结构采用双机双网并行工作模式设计。作为数据传输核心的通信子系统,采用双网热备路径冗余设计;作为数据处理与指令发布核心的处理服务器、数据库服务器和控制计算机,设计上都采用了双机并行技术。实践证明,上述技术的运用从系统结构上避免了由于单点故障而引起的系统宕机,提高了系统的可靠性和安全性。
The command and control system is an indispensable part of the aerospace landing test site and has completed the functions of pilot command, control, management, video monitoring, data analysis and processing, fault identification, simulation, timing and communication. The command and control system of a space landing test ground introduced by the article is composed of an active subsystem, a communication subsystem, a voice scheduling subsystem, a video monitoring subsystem, a large screen projection display subsystem, a data processing and storage subsystem, Taiwan, refers to significant workstations, software and other components. System structure using dual-network dual parallel mode of operation design. As the communication subsystem of the core of data transmission, dual-network hot standby path redundancy design is adopted. As the core processing server, database server and control computer of data processing and instruction issuing, dual-plane parallelism is adopted in the design. Practice has proved that the use of the above technology from the system structure to avoid due to a single point of failure caused by system downtime and improve system reliability and security.
