Embodiment 1( Embodiment approach 1
[0048] There is a motion sensor 1 that moves with the measured object that moves along the curve, and there are left and right uniform-speed synchronous motors 3 and 4 (motor A, B). The left and right uniform-speed synchronous motors rotate in the same direction, and the left and right uniform-speed synchronous The output shaft of the motor is respectively connected with reflective rods (called aluminum rods or metal rods) 5 and 6 (namely aluminum rods A and B) that have a reflective effect on infrared light and rotate with the motor output shaft. The output shaft of the motor is vertical, and the axis of the motor output shaft is the center of the rotating plane of the reflective rod. The rotating planes of the two reflective rods have an overlapping area, which is the effective detection area for object movement, that is, the moving range of the measured object is within the above In the overlapping area; there is a static sensor 2 fixed between the left and right uniform spe...
Embodiment 2( Embodiment approach 2
[0075] There is a follow-up motion sensor 7 (ie, the motion sensor M) that moves with the measured object that moves along the curve, and there are left and right uniform-speed synchronous motors 8 and 9 (namely, motors A and B), and left and right uniform-speed synchronous motors. The first and second moving sensors 10 and 11 (i.e. moving sensors A and B) are respectively fixedly installed on the output shaft, the first and second moving sensors are photoelectric transmitters, and the outer shells of the left and right uniform speed synchronous motors are fixed respectively. One, the second static sensor 12,13 (being static sensor A, B), the first and the second static sensor are photoelectric receiving devices, and the follow-up type dynamic sensor installs several photoreceiving devices within a circle of 360 degrees to ensure The object to be measured can receive the light signals from the first and second moving sensors at any position; Location.

Embodiment 3
[0093] Embodiment 3 (i.e. embodiment 3):
[0094] There is a moving sensor 14 (that is, a moving sensor M) that moves with the measured object that moves along the curve. The moving sensor 14 is fixed on the 15th axis of the synchronous uniform speed motor, and follows the motor to rotate at a synchronous and uniform speed. The synchronous motor is fixed on the measured object 16 and follows The object moves synchronously, and first and second static sensors 17 and 18 (i.e. static sensors A and B) are fixed on both sides of the measured object curve displacement track in addition; the dynamic sensor is a photoelectric emission sensor, and the first and second static sensors The sensor is a photoelectric receiving sensor, and the plane formed by the rotation of the axis of the light beam emitted by the moving sensor is perpendicular to the axis of the motor.
[0095] In the figure, the motion sensor M is fixed on the shaft of the synchronous motor and rotates synchronously with...
