An urban air public transport system comprises slow lanes, lanes, fast lanes, I-shaped steel rails, power lines, power line brackets, a tower, supports, cabins, cabin doors, conductive arms, power units, motors, wheels, wheel wings, side wheel shafts, main wheel shafts, side wheel micro-shafts, side wheel frames, side wheels, cabin connecting arms, passenger zones, buffer zones, driving zones, cabin brackets, stayed frames, lower connecting rods and upper connecting rods, wherein the towers and the supports are arranged at two sides of the pavement of an urban road; the two I-shaped steel rails are arranged at two sides of the top of each of the tower in parallel and are used for the balanced movement of the two cabins at two sides of the towers under the driving of the power units to reduce the gravity of the cabins and increase the riding safety; and the power lines provide power energy for the whole urban air public transport system and are installed on the power line brackets. The urban air public transport system has the advantages of simple making, strong maneuverability, low cost and obvious effect.

The invention relates to a steering controller of a high-power direct-current motor, which is composed of an input control module and a power output control module. The input control module comprises a forward input control circuit and a reverse input control circuit. The power output control module is that four power MOS (Metal Oxide Semiconductor) transistors are connected in parallel to form an H-bridge control circuit. The forward input control circuit comprises two circuits. The reverse input control circuit also comprises two circuits. Each circuit comprises a DC-DC (Direct-Current-Direct-Current) power module, a delay circuit, a photoelectric isolation circuit and a driving circuit. Two circuits of voltage signals output by the forward input control circuit are respectively transmitted to a power MOS transistor 1 and a power MOS transistor 3. Two circuits of voltage signals output by the reverse input control circuit are respectively transmitted to a power MOS transistor 2 and a power MOS transistor 4. By utilizing the modularization circuit design and a two-layer installation structure, the load capacity of the steering controller disclosed by the invention is up to 48 VDC / 120A. The steering controller is applied to the steering control of the high-power direct-current motor in a high-reliability occasion. The steering controller has the characteristics of being rapid in action speed, strong in current impact resistance capacity, steady for working and the like.
