The invention discloses a pantograph lower guide rod load sensor, a measuring system, a measuring method and a pantograph. The load sensor comprises a sensor body. The sensor main body is provided with N stress surfaces, each stress surface is integrated with a load chip, the N load chips are located on the circumference of the same section, one end of the sensor main body is provided with a stud, the other end of the sensor main body is provided with a stud hole, and N is an even number greater than or equal to 2. The embodiment of the invention provides a pantograph lower guide rod load sensor which can monitor the stress and bending moment of a lower guide rod in real time in the normal current collection working state of a pantograph and judge whether spherical hinges at the two ends of the lower guide rod are clamped or not through the stress and the bending moment.
