At step 110, meter reading information is obtained, wherein a command may be sent to a conventional digital meter using the 1997 or 2007 convention, requesting that the meter reading be transmitted, parsed and stored.
In step 120, each digit in the meter reading is converted into a binary code, such as a BCD code, as a signal bit to be transmitted. For example, the meter reading is 001286, each digit is converted into BCD code, and the low bit to high bit transmission can be also used as the high bit to low bit transmission, for example, the low bit to high bit transmission is used as the case, 6-8-2-1-0-0 is converted into 0110-. In addition, to prevent the transmitted numbers from being all 0, each digit of the reading of the electric meter can be converted into BCD code +1, for example, 6-8-2-1-0-0 is converted into 0111-.

At step 250, the switching signals are transmitted to an alarm database at predetermined time intervals. That is, the short circuit information and the open circuit information are transmitted to an alarm database of the LTE network management through an interface between the RRU and the user electric meter, for example, the predetermined time interval is 30 seconds, four codes can be simultaneously transmitted, so that 1 digit is transmitted in 0.5 minute, and the total reading of 6 digit electric meters needs 3 minutes.
