Claim 1:
2. The series-parallel monorail hoist based on the oil-electric hybrid power according to claim 1, wherein the monorail hoist further comprises a speed adaptive control system, the speed adaptive control system includes a load sensor configured to acquire a load weight of the monorail hoist and installed on the lifting beam, an inclination sensor configured to acquire upslope and/or downslope information of the monorail hoist and installed on a top end of the cabin, a speed sensor configured to acquire information of an operating speed of the monorail hoist and installed on the top end of the cabin, an electric energy sensor configured to acquire information of an electric power storage and in circuit connection with the power battery pack, an engine controller in circuit connection with the explosion-proof diesel engine, an AC/DC converter configured to control a charging and/or discharging of the power battery pack, a magnetic control valve configured to control an emergency shut-down and installed in a brake arranged in the gear track driving part and the hydraulic driving part, and a fuzzy PID controller installed in the cabin, the fuzzy PID controller includes a single-chip microcomputer and a PID regulator that are electrically connected with each other;
the explosion-proof motor, the speed regulating motor and the explosion-proof permanent magnet generator are electrically connected to a motor controller respectively;
the single-chip microcomputer is electrically connected with the load sensor, the electric energy sensor, the inclination sensor, the speed sensor, the motor controller, and the AC/DC converter respectively, and a target speed is calculated according to operation state information of the load weight, the electric energy storage, the upslope and/or downslope, and the speed of the monorail hoist; and
the PID regulator calculates a control quantity according to a difference between the target speed and a current speed, and sends a traction or braking command to the motor controller, the engine controller, a clutch controller of the transmission gear and the magnetic control valve that are electrically connected with the PID regulator, until the monorail hoist reaches the target speed.
