Artificial leg gait test system

The invention relates to a lower limb prostheses gait testing system, consisting of a simulation leg, a power source, a transmission device and a measurement and control system; the measurement and control system comprises a four-corner displacement sensor, a data collecting module, a motion control card and a computer processing system; wherein, the computer processing system is fixed on an external box body on the ground surface by a bracket; the four-corner displacement sensor is respectively arranged at two hip joints and two knee joints and used for collecting and simulating the joint angle change of the gait, and transmits the collected signal to the computer processing system by a data collecting module; furthermore, by the software of the control system and the collecting system, the collected gait joint angle data in the whole gait period when human walks normally is used as the control signal; the power source is controlled by a motion control card; the output of the power source drives the motion o
