Increase of civil security based on CAFM

Increase of civil security based on CAFM

The use of CAFM-dates to increase civil security is a central aspect of the BMBF-funded research project SPIDER (Security System for Public Institutions in Disastrous Emergency scenaRios). The extent to which CAFM can contribute to increasing civil security is presented on the basis of the research results achieved: CAFM systems contain numerous property-related data. After special data selection and processing, a CAFM system becomes the central data supplier for emergency services (fire brigade, ambulance service, hospital, police, ...) in a disaster or major damage situation. A connection to modern building management systems (GLT) of any real estate - in this Project to the GLT of koelnmesse - also enables employees to be alerted in the security control centre immediately after a fire alarm system has been triggered. Through the use of a special emergency protection module, employees are also given instructions on what to do. These minimise the danger of human error in emergency situations. Furthermore, an automatic transmission of safety-relevant property information is possible, e.g. the automatic transmission of the fire brigade run map of the triggered detector to the fire brigade's operations centre. If required, the current fire brigade plans as well as data from the hazardous substances cadastre of the CAFM system can be called up by the emergency services. Compared to the previous procedure, the early information leads to enormous time savings. The transmission and processing of various sensor data (smoke extraction system, smoke detectors, ...) for the end users also contributes to this. The process of triage of a property is accelerated, which ultimately leads to a faster rescue of injured and trapped persons. The connection to the BMS also includes an interface to people counting systems. The information about the current number of people within certain areas indicates in which areas - under the aspect of safety - further people can be granted access. In addition to the interfaces to the BMS, a connection to a (microscopic) people flow simulation was implemented together with the Chair of Physics of Transport and Traffic at the University of Duisburg-Essen. Via this connection, the current status information of various sensors (people counting, escape doors, smoke detectors, ...) available in the building management is exchanged. This makes it possible to simulate an evacuation of the property in multiple real time under the currently existing conditions in order to detect potential hazards such as increased densities or congestion before they occur. In this way, the personnel responsible for safety are given the opportunity to intervene preventively. In order to further optimise the evacuation, the situation-specific CAFM data and the results of the people flow simulation are processed using a graph-theoretical approach. This results in a unique circuit pattern for the escape route pictograms that is dynamically adapted to the situation. These direct people out of a property as quickly as possible to a safe area (e.g. assembly point) while avoiding current hazards such as fire, smoke and congestion. The evacuation is supported by automatic ELA announcements (electric loudspeaker system), which are made depending on the situation as well as the location. The research results show that through advanced use of CAFM data, interfaces to modern BMS and novel coupling of CAFM data with a people flow simulation, among other things, the following can be achieved: - automation of processes - reduction of human error - optimization of the rescue process - fast, safe and situation-dependent evacuation.
