Description

technical field [0001] The invention belongs to the technical field of metering instruments, in particular to metering instruments and management systems based on the Internet of Things and blockchain. Background technique [0002] There are two types of measurement methods for existing smart water meters. One is the mechanical type, that is, the impeller is placed in the water flow channel, and the gear mechanism is connected above the impeller. The gear mechanism displays the corresponding number on the dial, which is the water consumption. Another way is to measure by means of a sensor, that is, to realize the measurement by sensing the number of turns of the metering sensor pointer by a magnetic metering sensor, and this metering sensor pointer has magnetic or magnetic permeability. For water meters that are measured by sensors, some criminals, in order to steal water, use powerful magnets to place on the housing of the water meter meter, which interferes with the magnet...

Problems solved by technology

[0003] There are also some technical solutions in the prior art, such as the Chinese patent with application number CN201910943196.0, which includes a watch case, a filter screen is fixed inside the watch case, a base is fixed inside the filter screen, and a base is fixed inside the base An impeller is provided, a magnet is fixed on the upper end of the impeller, an outer cover is arranged above the impeller, and a groove is provided at the bottom of the outer cover, and the magnet at the upper end of the impeller extends into the groove, and the inside of the outer cover A copper inner cover is fixed, and a watch movement is installed inside the inner cover. The watch movement includes a mounting frame, a circuit board is fixed inside the mounting frame, a dial is fixed above the mounting frame, and the bottom of the mounting frame A gear shaft I is installed, and the gear shaft I extends from the bottom of the mounting frame to the dial, and is connected with the gear mechanism inside the dial; the bottom end of the gear shaft I is fixed with a magnetic steel I, and the magnetic steel I can drive the gear shaft to follow The magnet rotates; a snap ring is installed on the top of the watch case, and a transparent cover is installed on the snap ring, and the water measurement is accurate; but in this scheme, it is inconvenient to disassemble the water meter after it is closed, and it is difficult to carry out maintenance on the water meter. , the water meter is susceptible to external magnetic interference during use
