Embodiment 1
[0027] A kind of meter reading method based on the carrier gain terminal, a first carrier gain terminal is installed in the collector, and a second carrier gain terminal communicating with the first carrier gain terminal is installed in the electric energy meter, such as figure 1 As shown, the meter reading method includes:
[0028] Step 1, make the target electric energy meter send the electricity consumption information to the second carrier gain terminal;
[0029] Step 2, after determining the default value of the second transmission baud rate of the second carrier gain terminal, order the second carrier gain terminal to send the received power consumption information to the first carrier gain terminal;
[0030] Step 3, judge whether the second carrier gain terminal has received the information replied by the first carrier gain terminal within the preset time, if no reply message is received within the preset time, perform step 4, if received within the preset time When yo...

The invention provides a meter reading method based on carrier gain terminals, and belongs to the technical field of meter reading. A first carrier gain terminal and a second carrier gain terminal arerespectively mounted on a collector and an electric energy meter. The method includes the following steps: the target electric energy meter sends the electricity use information to the second carriergain terminal, the second carrier gain terminal sends the electricity use information to the first carrier gain terminal, whether the second carrier gain terminal receives information replied by thefirst carrier gain terminal is judged, and corresponding processing is performed according to the judgment result. The second transmission baud rate of the second carrier gain terminal is processed inreal time through the meter reading method until the second carrier gain terminal can communicate with the first carrier gain terminal in order to make the electricity use formation of the electric energy meter transmitted to the collector, so the electricity use information acquiring efficiency of the collector is improved.
Description
technical field [0001] The invention belongs to the technical field of meter reading, in particular to a meter reading method based on a carrier gain terminal. Background technique [0002] With the popularization of power line carrier communication technology at home and abroad, the proportion of the communication method using power line carrier in the meter reading system continues to expand in all meter reading systems. In the application process of the power line carrier communication meter reading system, the main The station sends the communication address code of the electric energy meter to the concentrator through the GPRS communication method, and the concentrator forwards the communication address code to the collector through the low-voltage power carrier communication method, and the collector obtains the information of the electric energy meter wirelessly according to the communication address code. [0003] Due to the influence of various factors such as weath...
