The invention discloses a suspended type single-rail traffic rail beam patrol car control device. The suspended type single-rail traffic rail beam patrol car control device solves the problems that inthe prior art, patrolling of a rail beam depends on manual patrol, the detection accuracy is low, and detection data of a slope and a curve is not accurate. The suspended type single-rail traffic rail beam patrol car control device comprises a patrol car body, a control device and a connection guide rail. The control device is fixed to the interior of the patrol car body, and the upper portion ofthe patrol car body is slidably connected with the rail beam through the connection guide rail. The control device comprises a wireless control system and a wireless charging coil connected with thewireless control system. The wireless charging coil comprises a plurality of emitting coils, a plurality of repeating coils and a receiving coil. The receiving coil is fixed to the upper portion of the inner side of the patrol car body. The invention further discloses a suspended type single-rail traffic rail beam patrol car control method, and the method comprises the four steps of building of aLagrange dynamics model, linearization of a nonlinear equation, building of a fuzzy control model and solving of defuzzification. The suspended type single-rail traffic rail beam patrol car control device is simple in structure, high in control accuracy, accurate in detection data of the slope and the curve, and long in service life.
