Zusammenfassung: | The invention discloses a direct-reading meter system, comprising a base meter, a photoelectric sensing device, a microcomputer control device, a receiving circuit, a transmitting circuit and a power circuit, wherein the base meter is connected with the microcomputer device through the photoelectric sensing device; the receiving circuit and the transmitting circuit are respectively connected with the microcomputer device; and the power supply circuit provides power for the microcomputer device. The direct-reading meter system in the utility model is in communication connection with a meter reader or a concentrator by using the M-BUS communication interface technology, allows wiring modes of any connection branches, such as cascade type, star type, crossed type and the like, uses common twisted-pair cables and can install wiring in a non-polarity two-wire system manner. The numerical value at the water meter counter winder can be directly read by a photoelectric system without adopting a pulse signal transmitt |
