Abstract
An M-BUS receiving circuit (8) and an M-BUS-based 4G water meter collector. The M-BUS receiving circuit (8) is disposed between a control unit (2) and an M-BUS overcurrent protection circuit, and is used for connecting the control unit (2) and the M-BUS overcurrent protection circuit. The M-BUS receiving circuit (8) consists of a voltage-stabilizing chip U1, Schmitt triggers U5B and U5C, voltage comparators U3A and U3B, triodes Q2 and Q4, diodes D1, D2, D8-D11, operational amplifiers U15A and U15B, voltage-stabilizing diodes ZW10 and ZW11, and several resistance-capacitance circuits. The M-BUS receiving circuit (8) 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.
