Multi-Sensor Approach for Monitoring Pipelines

Abstract

Pipeline vandalization is one of Nigeria's economy killer, since Nigeria economy to a great extent relies on oil in that capacity. Therefore, a third party damage to petroleum pipelines can be cataclysmic if undetected and prevented. This act results in budgetary misfortunes, ecological contamination and incessant death and loss of properties worth millions as an aftereffect of vandalization. Consequently, it is very paramount to protect these pipelines from vandals through intelligent monitoring systems. Several efforts have been made towards providing a reliable monitoring system for oil pipeline, however, no practically implementable solution have been achieved. Therefore, a pipeline monitoring system using multi-sensors is presented herewith. The sensor array consists of a Passive Infrared (PIR), vibration and sound sensor. An uninvolved infrared (PIR) sensor was utilized to detect intruders before they get in contact with the pipeline and for affirmation of intruders, sound and vibration sensor were set up. As the PIR recognizes an on-coming human the sound and vibration sensors affirms if the human is an intruder(s). An intrusion message containing the location of the vandals is sent to the appropriate authority by the microcontroller via a connected GSM module. Results obtained proved the system as a viable solution for detecting pipeline vandals.

“…Organic, gases, chemical and hazardous substances are increasingly produced day by day and their huge quantities are unsafe to human and environment, a system was proposed [23] to detect the leakages of gas that has an integrated module with embedded control. Another approach was proposed [24] for detecting motion along with a pipeline setup, the system notifies personnel via a multi-sensor setup of vibration and sound sensor. This idea was supported by [25] using sensors that help in pollution monitoring of petroleum products that could prevent any disaster.…”

“…The proposed system used ultrasonic sensor to establish an effective communication between the pumping machine and the water tank towards the avoidance of water wastage. [14] believe that due to increase in exodus to urban areas, mostly in the third world, there was an increase in generation of solid waste which if not properly managed, it can pose a great problem to local environment, hence the need to have a sustainably water management system to cater for the people and the environment Several attempts have been made towards providing a reliable monitoring system for water and other waste materials in the society, [17] developed an approach for detecting a system using a multi sensor to detect an intruder before they got in contact with a pipeline. The system had a sounds and vibration sensor which pre-inform the personnel concerned.…”
