In view of the real-time, reliable and efficient requirements in data transmission of the automatic meter reading system, a remote automatic meter reading scheme based on the technology of Wi-Fi is proposed. Wi-Fi (sometimes spelled Wifi or WiFi) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. Based on the transmission technology of Wi-Fi, this article introduces a remote automatic meter reading system, which takes UART-WiFi module as core and allows the meter connected to the Internet, so as to realize the function of network remote automatic meter reading.
