How does a smart meter realize remote meter reading?

The electric meter is connected to the collector through the wire, and the collector uploads the readings to the remote reading server through the network, and then the remote meter reading can be realized.

The traditional smart meter user holds the IC card to the power supply department to pay for the purchase of electricity. The power supply department uses the sales management machine to write the purchased electricity into the IC card. Same), you can switch on and supply power, and remove the card after power is supplied.

The current smart meters are different from the traditional mechanical meters. Now they are mostly electronic and inductive. After the meter head collector, acquisition board, and acquisition module are built-in, the metering data is collected through the RS485 interface line, power carrier, etc. The micro-power signal is transmitted to a concentrator (about 500-1000 units are collectively received).

Then transmit to the prepaid remote meter reading system (usually a database server) through the above three methods or GPRS, CDMA, network cable, etc., so that the smart meter collects the readings to the concentrator, and then to the remote meter reading system. Then to the user's prepayment query (meter opening and closing management), and finally to the entire process of the management end of the property power bureau.
