Abstract
Temperature distribution is a critical indicator of the health condition for Liquefied Petroleum Gas (LPG) storage tanks. In this paper, we present a large-scale wireless temperature monitoring system to evaluate the safety of LPG storage tanks. The system includes wireless sensors networks, high temperature fiber-optic sensors, and monitoring software. Finally, a case study on real-world LPG storage tanks proves the feasibility of the system. The unique features of wireless transmission, automatic data acquisition and management, local and remote access make the developed system a good alternative for temperature monitoring of LPG storage tanks in practical applications.
Highlights
The demand for energy resources increased sharply over the past decades in China
20 years [2], which will result in the consumption of 82 billion tons of coal, 12 billion tons of crude oil, and 5.8 trillion of natural gas
Accidents related to Liquefied Petroleum Gas (LPG) storage tanks lead to tremendous property and life losses [4]
Summary
The demand for energy resources increased sharply over the past decades in China. In 2014, it was estimated that China consumed 20% of the global energy [1], ranking the first in the world. Among various kinds of energy resources, the Liquefied Petroleum Gas (LPG) is recognized for its efficiency, environmental friendliness, and convenience. These unique features make LPG an ideal choice for rural heating, motor fuel, refrigeration, and cooking. As an alternative to manual surveying, various temperature sensors, and sensing systems for LPG storage tank monitoring has been investigated [7,8,9,10,11]. Yiwei et al designed a real-time distributed measurement system based on field bus technology for large-scale oil tanks.
