“…ACS uses CORBA to realize synchronous communication and asynchronous communication, provides services and runtime libraries for the control system, e.g., component/container services and astronomical libraries [56]. ACS is not only used in radio telescope, such as ALMA software [57] and SRT control software [58], but also in optical telescopes and physical devices [59][60][61][62][63]. However, ACS is seldom used in equipment and maintenance; updates have ceased after 2010.…”

The control system is the central control unit of the radio telescope. It is used to monitor, control, coordinate, and manage software and hardware systems so as to satisfy the requirements of high-precision control in astronomical observation of radio telescope. The control system architecture is the foundation for the implementation of the control system, which determines the stability, scalability, and maintainability of the control system. Furthermore, the architecture design of the control system is closely geared towards the technological development of radio telescope and computer software architecture. In this article, we analyze the characteristic of the control system of a radio telescope in various steps and discuss the development of their architecture and middleware framework. System architecture and middleware framework of control system also serve as a useful reference for the design of other radio telescope control systems.

“…The distributed control framework has many advantages, such as by hiding the details of the underlying mechanisms (such as message queues, asynchronous communication, thread pools, and lifecycle management) to helping engineers improve development efficiency; by standardizing device attributes and behaviors (such as data structures, interfaces, protocols, state machines) to provide a unified resource sharing and invocation for the system. Internationally, several large radio telescopes have adopted the distributed control framework for their ASFS, such as the Alma Common Software (ACS; Chiozzi et al 2004 andShen et al 2011), Ygor Clark 2002 andFord et al 2014), and Tango Controls (Baffa et al 2019).…”

The Tian-ma Radio Telescope (TMRT) applies an Active Surface System (ASFS), which corrects for large-scale deformations due to gravity and thermal on the primary reflector. The centralized and automated management of the ASFS using software has become a challenge, for which we have developed the TMRT Active Surface System Control Software (TASCS). This paper describes the design and implementation of TASCS for device control, status monitoring, human-computer interaction, and data management functionalities.TASCS adopts the open-source Tango Controls framework and distributed middleware technology to realize real-time automated adjustment of the primary reflector through remote centralized control of a large number of actuators. At present, it has been successfully deployed on the TMRT and has played an important role in Event Horizon Telescope (EHT) observations.
