Implementation of SCADA/HMI system for real-time controlling and performance monitoring of SDR based flight termination system

Abstract Flight termination system (FTS) is an important system to control and terminate a wayward flight vehicle under performance evaluation in test centre. Hence, the functional behavior assessment of the FTS system in real time is of utmost importance in test centre. In this paper, a Supervisory control and data acquisition (SCADA)/human machine interface (HMI) based system with integrated data acquisition (DAQ) facility has been designed, developed and implemented for controlling and monitoring of FTS remotely. The SCADA/HMI based system receives various intermediate processed data from FTS and parameters of onboard command reception system (CRS) from telemetry stations through Ethernet via FTS. It consists of HMI based control and monitoring unit, SCADA server, FTS and validated onboard receiver. All the FTS transmission, reception and onboard reception parameters are monitored and logged in real time, which is used for data analysis. Moreover, the FTS operational setting parameters are controlled by this system remotely. Hence, the developed system is a combination of SCADA/HMI as well as control and monitoring architecture based system implementation. The system architectures involved and the internal implementation of different modules are described here. The performance results are presented and the system is validated in real-time Tele-communication operation environment.
