CAFM, BIM and VR are some of the rising technologies that store and serve this data for numerous uses that vary from daily operation of facility management to emergency response conditions.
An IoT based mostly System for Fire Safety
These rising technologies when aligned together to enrich each other, can ship the promise of enhanced Fire Safety, enabling the promise of Smart buildings and cities which are safer.
Figure 1 : IoT system structure.
A typical architecture of such an IoT system is shown in Figure 1. At the edge of the system sit the pieces of hardware that actually detect the hearth. Typically these are constituted by Fire Panel systems or sensors of some type, usually Smoke, Gas Leak, Temperature or related other. The next degree of the system consists of hardware that communicates with the prior layer both via wired means similar to shielded RS485 or CAT6 cabling or via some form of wi-fi RF indicators. This layer sometimes consists of hardware referred to as as Nodes, Hubs or Gateways. Typically these Nodes, Gateways or Hubs are pieces of hardware which have entry to the Internet either by way of wired or wi-fi means. This layer communicates with the Cloud utility server utilizing IP protocol and communicates any event that is sensed by the ‘edge’ devices corresponding to fire panels or sensors which are linked with it. The well being of the system is being checked by each layer on an ongoing basis and communicated to the cloud server. เกจวัดความดันแก๊ส being monitoring activity is as crucial as the monitoring of any hearth occasion itself, as a result of the usefulness of the whole setup relies on the system being in a ‘healthy’ state. So not solely are the occasions themselves essential, however other elements similar to battery ranges of the sensor or panels, the RF connectivity between the sensors and the Gateway/Nodes and the internet availability on the Gateway/Nodes. The cloud server is the repository of all of the occasion and well being info and it additionally houses data pertaining to the actual real property in which the sensors and panels are housed. Such info can encompass Floor plans, Fire Evacuation plans, Building Asset data, Fire Fighting Equipment data, Fire Audit Information, Occupant Information and where relevant even surveillance cameras. All this crucial info must be linked to particular sensor info in order that if a hearth event happens, not solely are the first responders and affected occupants being made aware of the occasion, but also accompanying relevant and actionable info that may result in saving of life and property.
