[0055] In some alternative embodiments, the blade transport system provided in one embodiment of this application has two or more buffer components 30, which are spaced apart from each other.

[0056] The number of buffer components 30 can be two, three, or more.

[0057] By setting the number of buffer components 30 to two or more, elastic support can be provided to the blades at multiple points, effectively reducing the probability of collision between the blades and the transport equipment 10 and reducing damage to the blades.

And whether to alarm can be decided within 10S, when the pressure continuously triggers, the alarm is continuously issued, when the pressure triggers periodically, the alarm is periodically issued, that is, when the pressure returns to normal, the system no longer issues the alarm.

[0074] In some optional embodiments, the transportation system provided by one of the embodiments of the present application further includes a display 90, and the display 90 is configured to acquire and display the pressure value.
