TUDPL03 | Control System Simulation Using DSEE High Level Instrument Interface and Behavioural Description | 292 |
|
||
Funding: National Research Foundation of South Africa. National Centre for Radio Astronomy of India. Development of KATCP based control systems for the KAT-7 and MeerKAT radio telescopes proved the value of a fully simulated telescope system. Control interface simulators of all telescope subsystems were developed or sourced from the subsystems. SKA SA created libraries to ease creation of simulated KATCP devices. The planned SKA radio telescope chose the TANGO controls framework. To benefit from simulation-driven development tango-simlib, an OSS Python library for data-driven development of TANGO device simulators, is presented. Interface simulation with randomly varying attributes only requires a POGO XMI file; more complex behaviour requires a simple JSON SIMDD (Simulator Description Datafile). Arbitrary behaviour is implemented selectively using Python code. A simulation-control interface for back-channel manipulation of the simulator for e.g. failure conditions is also generated. For the SKA Telescope Manager system an Eclipse DSEE (Domain Specific Engineering Environment) capturing the behaviour and interfaces of all Telescope subsystems is being developed. The DSEE produces tango-simlib SIMDD files, ensuring that the generated simulators match their formal specification. |

THPHA085 | SKA Synchronization and Timing Local Monitor Control - Project Status | 1582 |
|
||
The Square Kilometre Array (SKA) project aims to build a large radio telescope consisting of multiple dishes and dipoles, in South Africa (SKA1-Mid) and Australia (SKA1-Low) respectively. The Synchronization and Timing (SAT) system of SKA provides frequency and clock signals from a central clock ensemble to all elements of the radio telescope, critical to the functionality of SKA acting as a unified large telescope using interferometry. The local monitor and control system for SAT (SAT. LMC) will monitor and control the working of the SAT system consisting of the timescale generation system, the frequency distribution system and the timing distribution system. SAT. LMC will also enable Telescope Manager (TM) to perform any SAT maintenance and operations. As part of Critical Design Review, SAT. LMC is getting close to submitting its final architecture and design. This paper discusses the architecture, technology, and the outcomes of prototyping activities. | ||
