[0002] Unmanned helicopter landing pads are primarily used for aircraft takeoff and landing. Due to the unique nature of aircraft takeoff, landing, and safety, the requirements for these landing pads are quite complex. Currently, many helicopter landing pads are located on rooftops of high-rise buildings or on elevated highways.

Existing emergency transport takeoff and landing correction platforms are set up on mobile, deployable vehicle-mounted landing pads for emergency rescue. However, existing emergency transport takeoff and landing platforms cannot automatically load emergency supplies onto unmanned helicopters for takeoff and landing. Utility Model Content
