The invention relates to the technical field of a water meter, discloses a device and method for detecting the number of turns of rotation, a storage medium and a water meter, and can improve precision of detecting the number of turns of rotation. The device comprises a chassis, a pointer with different magnetic poles at two ends, a first Hall switch, a second Hall switch and a data processing system, wherein the pointer rotates on the chassis by taking middle part of the pointer as the center, the first Hall switch is arranged on the chassis and located on the outer side of the pointer, the second Hall switch is arranged on the chassis and located on the outer side of the pointer, and the data processing system is electrically connected with the first Hall switch and the second Hall switch. The device is advantaged in that the first Hall switch and the second Hall switch are used for detecting two ends of the pointer, corresponding signals are fed back to the data processing system, the data processing system can effectively detect the number of rotation turns of the pointer according to the signals fed back by the first Hall switch, whether the pointer rotates forwards or reversely can be judged according to signals fed back by the second Hall switch, detection precision is improved, and thereby water quantity statistics of the water meter is achieved.
Description
Technical field [0001] The invention relates to the technical field of water meters, in particular to a detection device, method, storage medium and water meter for the number of rotations. Background technique [0002] When the existing water meters perform water volume statistics, they mainly judge the water volume by detecting the number of turns of the magnetic needle. The current detection method of the number of turns of the magnetic needle has defects, and the error of the water volume is likely to be too large only by the judgment. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention provides a detection device for the number of rotations, which can improve the accuracy of detecting the number of rotations. [0004] The present invention also provides a detection method of the detection device based on the number of rotations described above. [0005] The...
