Liquefied natural gas tank container transportation control system, method and device

The invention discloses a liquefied natural gas tank container transportation control system, method and device. The system comprises an environment monitor, a controller and a tank container control valve. The environment monitor is used for identifying a characteristic signal that the liquefied natural gas tank is about to enter a target environment, and the target environment is an environment with natural gas safety risks; the controller is used for responding to the characteristic signal and issuing a first exhaust instruction to the tank box control valve; the tank control valve is used for executing the first exhaust instruction so as to complete emission of gasified natural gas in the tank before the liquefied natural gas tank enters the target environment. According to the technical scheme, potential safety hazards caused by natural gas emission in the target environment can be avoided, and the transportation safety is improved. 本申请公开了液化天然气罐箱运输控制系统、方法和装置，系统包括环境监测器、控制器以及罐箱控制阀；环境监测器用于识别液化天然气罐箱即将进入目标环境的
