Abstract

The invention relates to a remote-control intelligent electric meter which can realize remote real-time control on electricity consumption information beyond visual range. The remote-control intelligent electric meter consists of an electric energy mutual inductance sampling part and a controller. The electric energy mutual inductance sampling part comprises an electricity consumption mutual inductor (1) and an A / D conversion sampling circuit; and a controller circuit comprises an overcurrent voltage detection circuit (11), an output control circuit (8), a power supply circuit, a CPU controller (3), a clock circuit (9), an LCD circuit (10), a data transmission circuit, a command transmission circuit and a buzzer voice prompting circuit. The remote-control intelligent electric meter can adjust and update electricity price information in the electric meter at any time so as to control electricity consumption, and remotely control a valve of the electric meter to be opened and closed according to amount of the residual electricity, thus realizing remote real-time adjusting function of electricity price and remote electricity consumption control on electricity consumption before payment.

Description

technical field [0001] The invention relates to an electric meter, in particular to a remote control smart electric meter capable of realizing remote real-time control of electricity consumption information beyond the visual distance. Background technique [0002] At present, domestic and international industrial processes are accelerating, and electricity consumption is becoming increasingly tense. This puts forward new requirements for metering meters, requiring pre-charges for electricity purchases, real-time monitoring of electricity consumption, and real-time regulation of electricity prices. However, the electric meters currently produced in China can be divided into two types in terms of payment forms: one is to pay first and then use them, such as IC card smart meters. The second is to pay after use, such as ordinary meters, remote meters, etc. The former has the characteristics of power failure when the pre-purchased electricity fee is exhausted, and the user must ...
