The Australia Telescope Compact Array consists of six 22-m antennas located on a 6-km East-West baseline. The geographical diversity of the array, the complexity of the antenna systems, and the vulnerability of the Observatory to damage from storms for example, makes effective monitoring and protection essential. We have implemented two monitoring, alarm and control systems which overlap in function. A hardware-based system examines a relatively small number of very important Telescope and environmental status inputs. A second system based on a minicomputer network acquires, checks and archives data from a much larger number of sensors. Our approach has enabled us to implement a relatively low-cost computer network and to proceed with complex software engineering tasks, including the current development of expert-system fault-diagnosis software, while being satisfied that the Telescope remains well protected. This paper describes the Telescope monitoring and protection schemes and discusses briefly the expected capabilities of the new expert system.
