[0093] As shown in Figure 7 The valve 12 is installed on the air inlet pipe 4, the air bag is placed between the goods to be protected when the air bag is used, the valve 12 is opened / twisted loose, the air cavity 3 is inflated by using a matched inflation device through the air inlet pipe 4, the air cavity 3 is gradually inflated during the inflation process, the valve 12 is closed / twisted tight after the inflation is completed, and air leakage is prevented; the valve 12 is opened / twisted loose after the work is completed, and is transferred to the storage place after pressure relief by using the handle 5.

[0094] The air bag of the application is used by being placed in the gap between cargos after being unfolded, the air inlet pipe is located above, the air is filled through the air inlet pipe 4 by using the air filling device, the air chamber 3 is inflated after the air filling is completed, the cargos on both sides of the air bag are separated, and the cargos are prevented from colliding. The air bag is connected by vulcanization of the same rubber, the rubber thickening layer 6 and the round corner design can make the internal stress distribution of the air bag more uniform after being inflated, can bear greater impact stress, provide greater buffering effect, and increase the safety guarantee of cargo transportation. After the air bag is used, the pressure is released through the air inlet pipe, the air bag is folded after the pressure release is completed, the lifting handle 5 is used to transfer to the storage place. The air bag can be identified by the RFID chip 7, the related technical information of the air bag is obtained, and comprehensive management and inventory control are carried out. The TPMS module 13 monitors the parameters such as air pressure and temperature in the air bag in real time (only pressure monitoring device can be used to monitor pressure), and transmits the data to the TBOX on the ship body. If the abnormality is found, the TBOX can actively inform the user through the display screen / display of the ship body in the form of message or pop-up window, and the risk is avoided in advance.
