| Safety Alarms at CERN |
| Abstract
In order to operate safely the CERN accelerators complex, the acquisition, transport and management of safety alarms is of a crucial importance. The French regulatory authority (Direction de Surêté des Installations Nucléaires de Base INB) defines them as level 3 alarms, they represent as such a danger for the life and require an immediate intervention of the fire brigade. Safety alarms are generated by fire and flammable gas detection systems, electrical emergency stops, and other safety related systems. Alarms level 3 are transmitted for reliability reasons to their operation centre: the CERN Safety Control Room (SCR) using two different media: the hardwired network and a computer based system. The hardwired networks are connected to local panels summarising in 34 security areas the overall CERN geography. The computer based system offers data management facility such as alarm acquisition, distribution, archiving and information correlation. The alarm level 3 system is in constant evolution in order to achieve better reliability and to integrate new safety turn-key systems provided by the industry |
| AMS-AC (Autorization Management System) and Databases for Access Control |
| Abstract
The concept for AMS-AC (Authorization Management System for Access Control) was developed in 1996/1997 with the participation of the divisions AS, DSU, PE, PPE, ST and TIS. It covers the entrance rules to CERN, types of CERN-CARDs and the access authorisations to controlled areas. The former paper based procedure, to obtain an access authorization, has been transferred to a database driven system with electronic signatures. All necessary information is stored in the human resource database (HR). From there the data is distributed to all card readers at CERN. A UNIX server is watching the updates of the authorization data and performs automatic data transfers. Additionally, several procedures have been developed: HTML-based on line database checks for immediate data control, database verification procedures, automatic information distribution. The presentation shows the way from the first registration of a person at CERN to the possibility to enter a controlled area. |
| The Technical Information Database for Systems Monitored by the TCR |
| Abstract
A database containing information pertaining to different technical systems monitored by the TCR has been in operation since the conversion of the BBC surveillance system to the LEP control system. This database contains all data that are of interest to monitoring applications such as the alarm system, the TDS, the equipment controllers and the surveillance of installations through mimic diagrams and data logging. It is important that the quality of this data is high so that an accurate picture of the systems being monitored is available at all time to both operators and equipment specialists. The information in this database is related to other data handled by ST such as equipment data used in the computerised maintenance system, location and personnel information; it is important that coherence between these systems is observed, if not rigorously implemented. This paper explains the role and implications of this database for the division. |
| Interface des Plans du Patrimoine Immobilier du CERN sur le World Wide Web (WWW) |
| Abstract
L'interface permet d’afficher à l’écran, les plans du PATRIMOINE CERN depuis le WEB. Un accès public sur WWW permettra de visualiser, réduire sensiblement la consommation de papier et la charge de travail du bureau des Plans et Données du Patrimoine. Deux solutions étaient envisageables: étudier une interface, ou utiliser celle qui existe dans CDD (Cern Drawing Directory). La deuxième solution a été retenue, car cette plate-forme fonctionne bien depuis deux ans. Le principe qui permet d’aboutir à ce résultat est le suivant: Les plans des sites et des bâtiments sont réalisés sur MICROSTATION au format natif DGN. Ils sont ensuite générés au format HPGL pour plotter et enregistrés dans CDD. Ces fichiers sont stockés sur un serveur SRV3_HOME/DIV_MT_A/Drawings/stce ... L’archivage de ces plans est fait automatiquement la nuit par CDD. La visualisation depuis le Web est réalisée depuis la page d’accueil CERN du menu Général, Divisions, Technical Support, TFM, Patrimony. |
| Feedback Control in Project-Based Management |
| Abstract
Project management is a well known management technique that has gained success because it encourages better organization and good engineering practice. This technique is also being used at CERN where projects are managed by engineers. They usually find themselves not at ease with a methodology and a jargon that are typical of an economical context. This paper presents a different approach to the project-based management. The notion of feedback control theory is introduced to help engineers in the organization and the supervision of the project as well as to provide a context that is more familiar to them. This new approach is illustrated for the AD Access Control project. |
