Abstract

The invention belongs to the field of communication technologies and instruments and meters, and provides a micro-power-consumption communication circuit and an electromagnetic watermeter. The micro-power-consumption communication circuit generates a first power source and a second power source which are isolated from each other through a power source isolation module according to electric energy provided by a battery module, and the first power source supplies power to a control module; the communication module is powered by the second power supply, the control module and the communication module which are isolated from each other can be powered by only one battery, the occupied space of the battery is saved, the structure is simple, and the size is small; the device can be widely applied to instruments such as flowmeters, thermometers or pressure gauges based on battery power supply and industrial environments with electromagnetic interference or lightning protection requirements on working sites.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a micro-power consumption communication circuit and an electromagnetic water meter. Background technique [0002] At present, the communication methods of battery-powered electromagnetic water meters mainly include wireless remote transmission, wired RS485 and meter bus (Meter Bus, M-BUS), etc. Among them, the communication method of wired RS485 has a nominal diameter (DN) of 40 mm and The above large-caliber water meters are widely used. [0003] However, the RS485 interface of the existing wired RS485 communication mode generally has an isolation function, so it needs to be powered by different batteries from the control chip, resulting in at least two batteries inside the electromagnetic water meter, the overall volume is large, and generally cannot Detect the power of the battery that supplies power to the RS485 interface.
