Quality safety traceability system and method in LNG transportation process

Abstract

The invention discloses an LNG transportation quality safety tracing system and a method, wherein the system comprises the following steps: a quality tracing cloud service platform is used for receiving, storing and analyzing module information, and sending the processed information to other modules; Intelligent terminal: the intelligent terminal is a device with information processing, mobile communication and positioning functions; The intelligent terminal is provided with a quality cloud tracing APP or a WeChat program; Power supply module: the power supply module is mainly provided by vehicle-mounted power supply and supplemented by lithium battery for external power supply; On-line monitoring module: the on-line monitoring module and the energy storage module are arranged in an inseparable integrated structure, and are installed on the pipelines of the liquid inlet and outlet and the gas inlet and outlet of the LNG storage tank; The temperature, humidity and vibration accelerationinformation of the outer wall of the pipeline are collected by the corresponding sensors, and the longitude and latitude information of the position is processed, and the clock information is stored,and then uploaded to the quality tracing cloud service platform through the mobile communication mode.

Description

technical field [0001] The invention relates to a quality and safety traceability system and method during LNG transportation. Background technique [0002] In recent years, with the maturity of LNG liquefied natural gas (Liquefied Natural Gas, the main component is methane, colorless, odorless, non-toxic and non-corrosive, liquefied at -162°C) in my country, coupled with domestic coal-to-gas, transportation gas With the advancement of projects related to air pollution control, such as chemical, natural gas power generation and distributed energy, the market demand for LNG is increasing day by day, and the market price of LNG is soaring, causing a large-scale gas shortage at one time. [0003] At present, domestic LNG land transportation mostly uses car trailers, ships, and trains to transport low-temperature LNG storage tanks. LNG storage tanks ensure that LNG transportation can be completed at an ultra-low temperature of -162°C. Some LNG suppliers and transporters want to o...

Problems solved by technology

Since the vehicle-mounted low-temperature LNG storage tanks transported by car trailers, ships, and trains are mobile tanks, the difference from stationary LNG storage tanks is that the LNG storage tanks are in a high-speed moving state most of the time. At this time, an explosion-proof Type transmitters or smart meters collect pressure, temperature, and liquid level. On the one hand, because the tank itself has no power supply, the vehicle power supply directly supplies power to the transmitter or smart meters. On the other hand, due to the special structure of the tank, power and signal Wiring is very limited and highly vulnerable to vandalism

At the same time, the pressure, temperature and liquid level collected by the vehicle are inaccurate and have little practical value

[0006] It can be seen that the quality assurance of LNG in the process of LNG transportation involves five major factors: people, vehicles, tanks, location, and LNG liquid. Effectively solve the problem of adulteration in LNG transportation
