Design and Realization of Web-based Multi-system Intermediate Frequency TT&C Integrated Equipment

从国外引进的地面测控设备在国内测控相关业务中广泛使用,其功能完备,但也存在系统集成度低、连接关系复杂、信号中继环节多等影响系统整体可靠性的弊端,并且成本高昂。针对高集成、小型化、智能化的测控设备需求,研究了嵌入式Web和软件无线电技术,提出了基于Web的多体制中频测控一体机设计与实现方案,测控一体机的核心功能是实现统一S频段、统一C频段和非相干扩频测控体制的遥控信号调制、遥测信号解调,以及测距测速。同时,设备还集成了信号源、功率计和频率计的部分功能,可实现对输入信号功率、频率和信噪比的测量。通过嵌入式Web设计,设备参数可以灵活动态配置,能够完成卫星地面测试、测控模拟和地面站测控等相关业务。

The ground TT&C equipment introduced from abroad is widely used in China.It has complete functions,but it also has the disadvantages of low system integration,complex connection relations,and many signal relay links that affect the overall reliability of the system,and the cost is high.According to the requirement of TT&C equipment for high integration,miniturization and intelligence,embedded systems and software defined radio(SDR)technology are studied,and a design and implementation scheme of Web-based multi-system intermediate frequency(IF)TT&C integrated equipment based on Web is proposed.The core function of TT&C integrated equipment is to realize telecommand signal modulation,telemetry signal demodulation,ranging and velocity measurement of unified S-band,unified C-band and incoherent spread spectrum TT&C system.The equipment also integrates some functions of signal source,power meter and frequency meter,which can realize the measurement of input signal power,frequency and signal-to-noise ratio.With flexible and dynamic configuration of device parameters through embedded Web design,the equipment can be used to realization satellite ground test,TT&C simulation,ground station TT&C and other related tasks.
