The invention relates to a monorail crane running speed hydraulic measurement system and method, and belongs to monorail crane overspeed automatic protection devices. The system is mainly composed ofa speed taking wheel, a coupler, a hydraulic system and the like. The hydraulic system comprises a pump, a detection loop, an oil drainage loop, an oil tank and the like. The pump serving as a power end of the hydraulic system is arranged in the detection loop, the detection loop is connected with the oil drainage loop, one end of the oil drainage loop is connected with the oil tank, and the otherend of the oil drainage loop is connected with an actuator; the detection loop comprises a hydraulic full bridge and a speed detection unit, and the speed detection unit is formed by connecting morethan one group of speed detection branches in parallel; and the detection loop further comprises an on-off control oil way, and the speed detection unit is directly connected with the oil drainage loop and the oil tank through the on-off control oil way. The monorail crane running speed hydraulic measurement system is simple in structure, speed detection is conducted through a driving part of a monorail crane, the mechanical structure is simple and reliable, the hydraulic system is stable and safe, and the system is suitable for occasions with high safety protection levels.
