| Abstract: | The paper introduced a method that LCD liquid crystal display unit of the smart electricity meter in automatic test line, which controlling the smart electricity meter switch to the specify display status via RS485 communication interface and protocol-specific commands of the smart electricity meter, and through taking pictures by the intelligent cameras, thus achieving the purpose of each screen and lights detection, This method not only realizes the LCD liquid crystal display unit of the smart electricity meter, also does not increase the equipment fault, Don"t influence the detection time, it makes the detection much completer, simpler and efficient. |
