Design of Monitoring and Warning System for Dangerous Gases in Oil Tank

摘要

Aiming at the hidden danger of harmful gas leakage and insufficient oxygen supply in the operating environment of oil tanks, this paper designs and implements monitoring and warning system for dangerous gas in the oil tank. The system uses the multilayer distributed structure, combines with various gas detection sensor technology and wireless communication technology, and adopts the STM32 microcontroller based on ARM Cortex-M3, with LoRa spread spectrum MESH ad hoc network module, 4G module, and OLED display module, and so on, to realize the collection and transmission of the gas concentration data in the oil tanker and display them on the upper computer software in real time. According to the field test of Zhongyuan shipping Automation Co., Ltd., the system meets the design requirements. It has the characteristics of low cost, flexible distribution, safe and practical and so on, which has a very good value for promotion.
