摘要

The system has a position maintenance part connected with a custom link token ring concentrator (TRC) (5) that is located in a headquarter unit (4). Interfaces are connected with an equipment maintenance part (41) to manage corresponding signals of alarms (42). Electronic devices (43) are provided with auxiliary switches. A connection part is provided between a management system (1) and TRC remote cards. A microcontroller includes an internal memory, two serial communication ports and an analog/digital electrical interface.
