Description
technical field [0001] The invention relates to a photoelectric direct-reading IoT prepaid gas meter based on positioning management. Background technique [0002] For remote meter reading, the core problem to be solved is how to convert the mechanical information measured and displayed by the meter into electronic information that can be processed by the computer, that is, data generation. In a traditional mechanical watch, a magnet is installed on a certain gear, and a magnetically sensitive device, such as a Hall element or a reed switch, is installed at the corresponding position. The magnet rotates with the gear, and when it enters the sensing area of the magnetic sensitive device, the reed switch pulls in and outputs the pulse, and then converts the pulse into flow through the counter circuit. The mechanical meter has the advantages of simple structure and easy realization, but the working principle itself determines that the mechanical meter has a fatal weakness, t...
