the step S2 road surface preheating is performed by the steps of: the method comprises the following steps: in the moving process, the road surface scanner (16) transmits the scanned data to the computer control cabinet (2) for analysis, and the second step is as follows: when a pit groove is detected, the computer control case (2) controls a piston of a hydraulic oil cylinder (4) to drive a shielding cover surface (7) to descend through a control system, an infrared heater (5) is electrified, and the infrared heater (5) generates microwave radiation to preheat the pit groove on the road surface; the step S4 of vibrocompaction is performed by the steps of: through the compaction mechanism (15), the control system and the hydraulic system are matched, and the compaction hydraulic cylinder (15-4) repeatedly stretches and retracts, so that the compaction roller (15-5) can vibrate and compact the surface of the pit groove, and the repaired pavement can reach a certain compaction degree; the cleaning and acceptance in step S5 includes the following steps: after compaction, a layer of stone powder or fine sand can be uniformly scattered on the surface, and a cleaning tool is used for cleaning back and forth so as to fill the surface gaps with the stone powder or fine sand; the peripheral corners of the pit groove are compacted without loosening; the step S3 of processing and adding the repair material and flattening is performed by the following steps: controlling a discharging channel (13) to enable different types of repairing capsules to fall into a microwave heating box (21) for primary treatment and heating, then controlling a micro roller shutter at the bottom of the microwave heating box (21) to be opened to enable materials to be discharged from a discharging nozzle (9), enabling the materials to fall into an inner shell (19-6) of a stirring container in a microwave repairing mechanism (19), then carrying out microwave heating on the materials through a microwave emitter (22) arranged on the stirring container, fully stirring the materials by matching with an electric stirring knife (19-2), making the materials directly used for pit and groove repairing, then sensing the position of a preheated pit and groove through a temperature sensor (7), and controlling a repairing mechanical arm mechanism (8) to rotate and move through a computer control cabinet (2) to enable the materials to be accurately placed into the pit and groove to be repaired through the opening of the container; a micro motor in the electric stirring knife (19-2) controls a blade of the electric stirring knife (19-2) to rotate at different rotating speeds, and a container opening (19-5) at the bottom of an inner shell (19-6) of the stirring container is controlled to be opened and closed by a control system; the output method of the repair material in the step S3 is performed by the following steps: the repairing part of the repairing mechanism is positioned on the right side of the preheating part, the repairing mechanical arm mechanisms (8) are positioned below the discharging nozzles (9), and the number of the repairing mechanical arm mechanisms is three; the temperature sensor (7) is positioned on a mechanical arm base (8-1) of the repairing mechanical arm mechanism (8) and used for sensing the position of the preheated pit slot; the control method of the robot arm control system in step S3 includes: the electric stirring knife (19-2) is controlled to rotate at different rotating speeds by the repairing mechanical arm mechanism (8); the stirring container outer shell (19-3) is arranged at the tail end of the telescopic folding arm II (8-6), and the stirring container outer shell (19-3) can be kept in a vertical state no matter how the mechanical arm rotates; a metal shielding net (19-4) is arranged at the outer side of the microwave emitter (22); meanwhile, the main arm and each folding arm can stretch out and draw back, and each arm adopts a hydraulic control mode to stretch out and draw back and rotate each arm; the control method of the compaction mechanism in the step S4 comprises the following steps: a second compaction guide rail (15-2) in the compaction mechanism (15) is fixed at the tail part of the chassis (14) by bolts, the first compaction guide rail (15-1) is connected with the second compaction guide rail (15-2) by a guide rail pressure plate, a hydraulic system controlled by the computer control cabinet (2) drives the first compaction guide rail (15-1) to move relatively along the second compaction guide rail (15-2), the maintenance vehicle is fixed and does not move, one end of a compaction swing rod (15-3) is fixed on a first compaction guide rail (15-1), the other end of the compaction swing rod is connected with a rotating shaft of a compaction roller (15-5), a cylinder barrel of a compaction hydraulic cylinder (15-4) is fixed at the other end of a second compaction guide rail (15-2), a telescopic rod is fixed in the middle of the compaction swing rod (15-3), and the compaction hydraulic cylinder (15-4) controls the lifting and compaction of the compaction roller (15-5).
