A smart monitoring system for gas cylinders used in liquefied natural gas vehicles

Abstract

The invention discloses a smart monitoring system for vehicle gas cylinders of liquefied natural gas vehicles, which includes a vehicle gas cylinder data collection sheet, a vehicle gas cylinder data collection and transmission terminal, a cloud server, and a monitoring platform; the vehicle gas cylinder data collection unit uses To collect the relevant data of LNG vehicle gas cylinders and output them to the vehicle gas cylinder data collection and transmission terminal; the vehicle gas cylinder data collection and transmission terminal is used to send the relevant data of the LNG vehicle gas cylinders to The cloud server; the monitoring platform is used to obtain data from the cloud server to monitor the gas cylinders of LNG vehicles. The invention can effectively monitor the whole state information of the gas cylinder used in the liquefied natural gas vehicle during use, is safe and reliable, convenient in application, accurate in monitoring, and ensures the safety of use and driving.

Description

technical field [0001] The invention relates to the technical field of gas cylinder monitoring for liquefied natural gas vehicles, in particular to an intelligent monitoring system for gas cylinders for liquefied natural gas vehicles. Background technique [0002] With the strengthening of national environmental protection policies, the requirements for vehicle exhaust emissions are becoming stricter. Vehicles powered by liquefied natural gas (LNG) have excellent environmental protection, and their development and application are rapid. The gas cylinder for liquefied natural gas vehicles is a low-temperature heat-insulated pressure vessel that is used to replace automobile fuel tanks for filling and storing, and to supply automobile fuel, and can be refilled many times. Liquefied natural gas has the characteristics of easy evaporation and high liquid-gas ratio. The vacuum degree of the interlayer of cryogenic containers will gradually deteriorate with time and the influence ...

AI Technical Summary

Problems solved by technology

Liquefied natural gas has the characteristics of easy evaporation and high liquid-gas ratio. The vacuum degree of the interlayer of cryogenic containers will gradually deteriorate with time and the influence of internal and external factors. If effective monitoring measures are not taken, there will be safety risks at any time due to the influence of the harsh external environment during use. If an accident occurs, it will cause serious social consequences and property losses; Scattered distribution of cylinders, especially vehicle gas cylinders that move with vehicles, are greatly affected by external unsafe factors, with high safety risk factors and difficult supervision

At the same time, the existing liquefied natural gas vehicles lack the three-dimensional monitoring of LNG vehicle gas cylinders and their vehicles. The fusion monitoring application of bottle state parameters and vehicle parameters has not caused the safety and management efficiency of LNG vehicles to be limited
