The invention discloses an
Internet of Things intelligent water meter capable of working without power supply. A mechanical water meter has the functions of supplying water, metering, uniformly displaying
water supply metering and closing a valve; the superposed circuit on the mechanical water meter has the functions of charging, fee display, management and
valve opening; a valve capable of being automatically closed without
electricity when control is not added is installed on a
water supply channel in the water meter, the condition that water charge closed-loop management
water supply conditions are not met when water charge is not received, the valve is attacked and damaged, mechanical faults, circuit faults and battery power shortage and shortage are caused, and the valve is automatically closed without
electricity after one round of water supply is completed; the circuit converts the supplied
water volume physical quantity into the collected electronic
digital currency quantity in each round of water supply process, and the water meter is recovered to a new round of water supply initial state after charging; closed-loop
payment exchange between physical goods and electronic currency is realized; the mechanical / electronic double-metering and double-display mode that mechanical metering of an existing electronic water meter is electromechanically converted into electronic metering and then secondarily converted into electronic currency is changed; and no pulse equivalent exists.
