Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1-6 are a specific embodiment of the present invention, which is a non-magnetic inductive rotary sensor for water meters and gas meters, and is composed of a first PCB coil L1, a second PCB coil L2, a third PCB coil L3, a sampling disk D, a control circuit and a battery.
As shown in fig. 1, the third PCB coil L3 is an annular coil; as shown in fig. 2, the first PCB coil L1 is composed of two centrosymmetric coils wound in a right-angle sector shape in series, which are respectively a first PCB coil first sub-coil L1-1 and a first PCB coil second sub-coil L1-2, and the winding directions of the first PCB coil first sub-coil L1-1 and the first PCB coil second sub-coil L1-2 are clockwise one and counterclockwise the other; as shown in fig. 3, the second PCB coil L2 is composed of two centrosymmetric coils wound in a right-angle sector in series, where the winding directions of the first sub-coil L2-1 and the second sub-coil L2-2 of the second PCB coil are clockwise one and counterclockwise the other of the first sub-coil L2-1 and the second sub-coil L2-2 of the second PCB coil respectively; as shown in fig. 4, the first PCB coil L1 and the second PCB coil L2 are stacked together at an angle of 90 degrees, and the third PCB coil L3 is stacked on the outer periphery of the first PCB coil L1 and the second PCB coil L2. As shown in fig. 5, the stainless steel disc angle is set between 180 and 270 degrees depending on the distance of the stainless steel disc from the PCB coil.
As shown in fig. 6, when the impeller rotates, the stainless steel disc D is driven to rotate, and different induced voltages are generated at different angles by applying an excitation pulse to the third PCB coil L3 of the excitation coil at regular time, and generating induced voltages on the first PCB coil L1 and the second PCB coil L2. Taking a 180-degree stainless steel plate as an example and a first PCB coil L1 as an example, because the windings of a first sub-coil L1-1 of a first PCB coil and a second sub-coil L1-2 of a first PCB coil which form the two sub-coils of the first PCB coil L1 are clockwise and anticlockwise, the directions of induced currents on L1-1 and L1-2 are opposite, and the induced voltage generated at two ends of the first PCB coil L1 is the sum of the induced voltages on L1-1 and L1-2. The size of the induced voltage is related to the area of the coil and whether the stainless steel semicircular disc D covers the coil. Because the area of the coil is fixed, the size of the induced voltage is related to the area of the coil covered by the stainless steel semicircular disc D, when the stainless steel semicircular disc D rotates, the area covered by the stainless steel semicircular disc of the L1-1 coil and the area covered by the stainless steel semicircular disc of the L1-2 coil can be increased and decreased, and when the disc rotates periodically, the total voltage on the first PCB coil L1 can change according to the periodic rule of 0, maximum, 0 and minimum.
The induced voltage generated at the two ends of the second PCB coil L2 has the same periodic variation law as the induced voltage at the two ends of the first PCB coil L1.
By amplifying the signals of the induced voltages VL1 and VL2 and comparing the signals with a comparator, 4 states as shown in fig. 6 can be detected, a state machine list is formed by the 4 states, and the number of rotation turns can be calculated according to the change of the state machine in the rotation process.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
