PC BASED ALARM ANNUNCIATOR SYSTEM

At present, Panel-Based Alarm Annunciator System for the existing 130Mev AVF cyclotron of our centre is used to draw the attention to the operator only for the 64 Nos. of top-level alarms. The lower level faults, which cause the top level alarm, are not visible from the control panel. Moreover, huge amount of maintenance cost and manpower is involved in keeping the system alive. To alleviate these problems, one PC-Based Alarm Annunciator System has been developed using C++ [1] under WIN-NT. A PC plug-in card from ADVANTECH [2] is used for the Input/Output ( I/O ) interface. The 64 top level alarms are displayed on the screen using buttons with pre-defined names and different colors are used to indicate the system’s status ; e.g. RED for fault, GREEN for O.K. and BLINKING with AUDIO for alarms. Lower level alarms can be displayed with a mouse click on the top-level alarm button. The system keeps records of different parameters with time stamp in a database. The facility to monitor the on-line status of the alarms over the network, through WWW browser is also incorporated. The system is working satisfactorily and will be connected with the main system shortly.
