An Integrated Surveillance System to Detect Fire and Gas Leakage in Petrochemical Industry Using Zigbee Protocol

C.Vinothkumar,K.Kumar,R.Elavarasan

Integrated industrial plant fireplace and gas surveillance system using Zigbee is designed to monitor fire and gas leakage and population density in the hazardous locations within the Petroleum refinery. The existing system detects any fire or any gas leakage with in geographically distributed areas. Increase in the complexity of process industry leads to increase in the number of instruments to detect fire and leak. This increases the number of cables that run from industrial sensors to the control station. This increases the bulk of the channel. Troubleshooting the reduced insulation or any wire open is difficult because it is a messy wiring and identifying the individual cable is very difficult along the duct. This also increases the system cost in terms of cable cost. So to cope up with the modern technology it is proposed to have a wireless communication between field devices and the control room. With the advent of wireless technology many parameters can be sent over a single communication medium. This reduces the messy wiring and making trouble shoot easy. The field device can be a portable or a fixed device which communicates the various parameters that are being monitored, to the control room through Zigbee protocol.
