Abstract

The invention discloses an intelligent four-digit direct reading wireless header. The header comprises an opposite type word wheel box and circuit boards installed inside the opposite type word wheelbox, a plurality of independent hollow chambers are formed in the opposite type word wheel box, the circuit boards include photovoltaic panels and wireless CPU boards, and the photovoltaic panels arewelded with the wireless CPU boards; sealing compounds are poured into the hollow chambers in which the circuit boards are installed, and the sealing compounds seal the circuit boards. According to the header, the sealing compounds are adopted to seal the circuit boards so as to solve the problem of short circuit caused by water seepage of the circuit boards.

Description

technical field [0001] The invention relates to a meter, in particular to an intelligent four-digit direct-reading wireless meter. Background technique [0002] The photoelectric direct reading water meter adopts photoelectric direct reading technology to read the word wheel data. Compared with the traditional pulse meter, it can reduce the reading error to zero. It is an electronic remote water meter with zero error in electromechanical conversion in the automatic meter reading system. Low power consumption design, usually no power supply is needed, only when reading meters or valves, it needs to be powered. The photoelectric direct-reading water meter cooperates with the intelligent meter reading system equipment to complete the intelligent reading of the water, electricity, and gas meter data in the community, and realizes data sharing with the settlement center; the civil water meter market needs to achieve a minimum of 4 digits and 4 digits according to national require...
