Abstract
An M-BUS receiving circuit () and an M-BUS-based 4G water meter collector. The M-BUS receiving circuit () is disposed between a control unit () and an M-BUS overcurrent protection circuit, and is used for connecting the control unit () and the M-BUS overcurrent protection circuit. The M-BUS receiving circuit () consists of a voltage-stabilizing chip U, Schmitt triggers UB and UC, voltage comparators UA and UB, triodes Qand Q, diodes D, D, D-D, operational amplifiers UA and UB, voltage-stabilizing diodes ZWand ZW, and several resistance-capacitance circuits. The M-BUS receiving circuit () can greatly increase the signal-to-noise ratio, and the reliability and stability thereof are significantly improved. Similarly, the M-BUS-based 4G water meter collector can effectively improve the stability of water meter data collection.
