Abstract: |
We developed a system to reduce the cost of monitoring potential gas leaks and streamline the process of gathering/analyzing data collected. In 2015, Aliso Canyon in the United States was the center of the largest natural gas leak in history: releasing 97,000 tons of methane and 7,000 tons of ethane. Currently, gas monitoring systems are either not very robust or very expensive.
To reduce the risk of a major natural gas leak incident, our team developed a low-cost Internet of Things (IoT) Monitoring System. We create a flammable/toxic gas monitoring system that is low-cost, can be deployed over a wide area, has robust communication, and can be provisioned quickly and easily. Essentially, the installer can simply place and secure a self-contained portable monitoring unit in any appropriate location, push/tap a button on their smartphone/tablet, and the new node will configure itself to be part of the monitoring system.
Our IoT gas monitoring system consists of a network of sensor nodes placed around potential containers, transport facilities, pipelines, or openings that might leak. The first phase of the system involves sensor node modules, a communications network for the nodes, and a central interface. The nodes are built with the relevant gas sensor (methane, ethane, etc.), solar panels and batteries for power, and inexpensive communication modules. The system provides connectivity for each node’s data using a variety of communication standards such as Bluetooth, WiFi, or LoRa, depending on the distance between the nodes. Each node’s data is relayed toward the central node and aggregated to the cloud database. The user interface is built to work on a multitude of platforms (Android, iOS, Windows, macOS), providing data access to the cloud database and thus the geographic reading of each node.
In this way, we provide real-time data on sudden changes in gas storage and transportation facilities and provide rapid response times. While this system is targeted toward the natural gas industry, it severs as a template for low-cost monitoring systems in various other industries and fields. |
