[0095] refer to Figure 3 In step S12, in the state of the natural gas warehouse, the environmental parameters in the natural gas warehouse are collected; and the environmental state inside the natural gas warehouse is defined according to the environmental parameters in the natural gas warehouse;

[0096] In the specific implementation process of the present invention, the specific steps may be:

[0097] S121: In the state of the natural gas tank, collecting multiple environmental parameters in the natural gas tank;

[0098] S122: constructing an internal environment set based on multiple environmental parameters, and constructing an internal environment model according to the internal environment set;

[0099] S123: the internal environment model defines the change amount of each environment parameter over time;

[0102] S126: Associating the second environmental coefficient with the first environmental coefficient, and defining the environmental state inside the natural gas storage tank according to the second environmental coefficient and the first environmental coefficient.

[0103] In an embodiment of the present application, when the natural gas tank is in a state, multiple environmental parameters in the natural gas tank are collected to facilitate the control of the internal environment of the natural gas tank, thereby constructing an internal environment set based on multiple environmental parameters, and constructing an internal environment model based on the internal environment set, thereby ensuring the internal environment model of the natural gas tank and realizing real-time monitoring of the internal environment model. At this time, the internal environment model defines the change amount of each environmental parameter over time.

[0104] Furthermore, in the internal environment model, multiple environmental parameters are combined and multiple environmental combinations are constructed, and the first environmental coefficient is defined based on the multiple environmental combinations, thereby clarifying the first environmental coefficient. At the same time, the change amount of each environmental parameter is collected, and a change amount set is constructed according to the change amount of each environmental parameter, and the second environmental coefficient is defined based on the change amount set.

[0108] S131: freeze the natural gas transport vehicle in a uniform moving state;

[0109] S132: When the natural gas transport vehicle is in a uniform moving state, define the illumination area of ​​the natural gas warehouse;

[0110] S133: If the illumination area of ​​the natural gas warehouse is greater than the preset illumination area, triggering the collection of parameters of the natural gas inside the natural gas warehouse;

[0111] S134: defining a plurality of physical parameters of the natural gas in the natural gas storage tank based on the parameter collection of the natural gas in the natural gas storage tank;

[0126] In an embodiment of the present application, the activity state of natural gas is frozen, and the environmental state inside the natural gas warehouse is collected, and the activity state of natural gas and the environmental state inside the natural gas warehouse are correlated, so as to control the activity state of natural gas and the environmental state inside the natural gas warehouse, so as to monitor the activity level of natural gas, so as to comprehensively control the natural gas and the environment in which it is located.

[0127] At this time, the matching coefficient is defined according to the active state and environmental state of the natural gas, and the matching coefficient is compared with the preset matching threshold. Therefore, if the matching coefficient is greater than the preset matching threshold, the matching level is defined according to the matching coefficient; if the matching coefficient is less than the preset matching threshold, a review of the active state of the natural gas or the environmental state inside the natural gas tank is triggered, and the review result is output, and the adjustment of the environmental state is triggered based on the review result until the matching coefficient reaches the preset matching threshold.
