Embodiment Construction
[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0063] see figure 1 , which is a schematic diagram of the module composition of the water meter direct reading system 200 provided in the best embodiment of the present invention. The water meter direct reading system 200 is used to read a plurality of liquid-sealed direct reading water meters 100. Sealed direct-reading water meters 100, a plurality of photoelectric identifiers 201 installed in multiple liquid-sealed direct-reading water meters 100 and electrically connected to MCU300, and installed in MCU300 in the form of software for liquid-sealed direct-reading through photoelectric identifiers...

The invention relates to a water meter direct-reading system which comprises a liquid-sealed direct-reading water meter and a processing module, wherein the liquid-sealed direct-reading water meter comprises a character wheel and a photoelectric identifier corresponding to the character wheel; each number of the character wheel takes up 36 degrees, and the character wheel is provided with a plurality of first color printing codes and second color printing codes which are arranged at certain intervals; the numbers on the character wheel are defined into corresponding binary numerical values through corresponding first color printing codes and second color printing codes and the photoelectric identifier so as to form a memory table; and a data sampling sub-module of the processing module is used for controlling the photoelectric identifier to generate a corresponding identification curve, and a degree acquisition module of the processing module is used for acquiring a corresponding binary numerical value according to the identification curve, carrying out table searching according to the memory table and finding out a number matched with the binary numerical value so as to form the meter reading degree. The water meter direct-reading system has better meter reading accuracy. The invention also relates to a liquid-sealed direct-reading water meter applied to the water meter direct-reading system, and a water meter direct-reading method.
Description
technical field [0001] The invention relates to a water meter, a water meter direct reading system with the water meter and a direct reading method thereof, in particular to a liquid-sealed direct-reading water meter, a water meter direct-reading system with the liquid-sealed direct-reading water meter and a water meter direct-reading method.
