Early Fire Detection and Safe Exit Guidance System (EFD-SEG)

Early Fire Detection and Safe Exit Guidance System (EFD-SEG)

Brief Description

Fire can result in life threatening disasters and can be caused due to a variety of reasons. An early fire detection system becomes of critical importance in such circumstances. C-DAC’s EFD-SEG system senses the abnormal rise in the in-line current & voltage, temperature, humidity, LPG leakage, smoke and sends the information through Wi-Fi (802.11 b/g/n) to a control room (server). The end users will be connected to the server through the deployed Wi-Fi infrastructure. In case of an emergency, a mobile app on the user’s phone provides the possible navigational paths flashing the fire location and the crowd density at the possible exits. Furthermore, by accurately locating the source of fire, this information is made available to fire fighting and other security agencies for effective mitigation of fire and to bring the situation under control. The two hardwares responsible for sensing and preventing fire are the EFD Sensing Node and the Protective Relay Node.

EFD Sensing Node

EFD sensing node is a Wi-Fi enabled device which senses the local temperature, humidity, gas (LPG, CO2 etc.) and smoke and sends the corresponding data to a remote server. The data can be viewed and analyzed remotely from a dashboard. In case of any fire hazard, the registered local and regional fire authority is intimated through SMS and e-mails. The system can also be used for indoor comfort analysis.

Protective Relay Node

Protective Relay Node is a Wi-Fi enabled device which senses the supply voltage and the in-line current and sends the corresponding data to a remote server. Similar to the EFD sensing node, the data can be viewed and analyzed remotely from a dashboard. In case of any fire hazard, the registered local and regional fire authority is intimated through SMS and e-mails. Majority of fire incidents happen due to electrical malfunction. This device acts as a protective shield against such incidents.

EFD Dashboard

EFD dashboard is enabled with multitudinous features. The map of the building, where the EFD solution is deployed, can be loaded on the Home page. The map shows the various deployed EFD Sensing Node and Protective Relay Node and the last received data value. The node display is color coded to reflect various states of the node like normal state, intermittent state, alarm state, off state etc. Data can be exported and time-plots can be generated from the dashboard. Frequency of data collection can also be changed from dashboard.
