The IHEP Accelerator Utility Control System (AUCS) comprises hardware and software designed to automate the safety equipment thus increasing the effectiveness of accelerator operations staff and utility control staff. Since AUCS sub-systems would be installed in all operational buildings of the accelerator, a hierarchical structure is the obvious solution for the AUCS hardware. Every building would be equipped with the hardware measuring signals from various kinds of technological parameter sensors and controlling actuators in functional sub-systems. The data acquisition and control hardware is built in Euromechanics (EM) crates with MULTIBUS1 backplane bus. A PC-16 module with an i8086 microprocessor is used as a crate controller in this configuration. Data acquisition and control crates of EM are connected to the Utility Control Computer (UCC). At the same time UCC ensures the communications through the Network with the accelerator control computers , as well as with the central accelerator control console and local consoles in operations buildings or utility consoles in respective services buildings.
