To accurately determine a work state of a concrete mixer truck.SOLUTION: A work state determination system 100 includes: a rotation sensor 12 which detects a rotation state of a mixer drum 2 of a concrete mixer truck 10; a pressure sensor 14 which detects driving force for rotationally driving the mixer drum 2 of the concrete mixer truck 10; and a determination part 21 which determines a work state of the concrete mixer truck 10 based on detection results of the rotation sensor 12 and the pressure sensor 14. The determination part 21 determines whether or not ready-mixed concrete is placed into the mixer drum 2 and the concrete mixer truck 10 becomes a delivery state based on a detection value of the rotation sensor 12 and a detection value of the pressure sensor 14 in a predetermined detection period in a parking state of the concrete mixer truck 10.SELECTED DRAWING: Figure 2
