Problems solved by technology
[0002] When the existing water meter performs water volume statistics, it mainly judges the water volume by detecting the number of rotations of the magnetic needle. The current detection method of the number of rotations of the magnetic needle has defects, and the error of the water volume is likely to be too large only by judging

The invention relates to the technical field of water meters, and discloses a detection device, method, storage medium and water meter for the number of rotations, which can improve the accuracy of detecting the number of rotations. The invention comprises: a chassis; pointers with different magnetic poles at both ends, centered on the middle of itself and rotating on the chassis; a first Hall switch arranged on the chassis and outside the pointer; a second Hall switch arranged on the On the chassis and outside of the pointer; the data processing system is electrically connected to the first Hall switch and the second Hall switch respectively. The present invention simultaneously uses the first Hall switch and the second Hall switch to detect both ends of the pointer, and respectively feeds back corresponding signals to the data processing system, and the data processing system can effectively detect The number of rotations of the pointer is displayed, and at the same time, according to the signal fed back by the second Hall switch, it can be judged whether the pointer is rotating forward or backward, which improves the detection accuracy and realizes the water volume statistics of the water meter.
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] Existing water meters mainly judge the water volume by detecting the number of rotations of the magnetic needle when performing water volume statistics. The current detection method of the number of rotations of the magnetic needle has defects, and the error of the water volume is likely to be too large only by judging. Contents 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 proposes a detection device for the number of rotations, which can improve the accuracy of detecting the number of rotations. [0004] The present invention also proposes a detection method of the detection device based on the above-mentioned number of rotations. [...
