Embodiment Construction

[0021] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0022] see figure 1 , the present embodiment relates to a method for automatic searching of electric energy meter addresses, which includes steps:

[0023] A) Send the meter reading frame with all A addresses for broadcast meter reading;

[0024] B) Whether the energy meter is found. Wait for the response data frame within the set timeout period. If there is no response after the timeout, the search process will end, and if the response is received, the steps will continue.

[0025] The above two steps can also be referred to as the first round of table lookup. After the meter reading frame with all A addresses is sent by broadcast, if there is no meter, that is, there is no response within the timeout period, and the meter search proce...

Abstract

The invention provides an automatic energy meter address searching method. The automatic energy meter address searching method comprises the steps that firstly, full-A address meter reading frames are sent for conducting broadcast meter reading, then, whether an energy meter exists or not and whether a plurality of energy meters exist or not are judged according to returned data frames, furthermore, energy meter abbreviated address searching is used for conducting multiple times of meter searching, therefore, addresses of the real energy meters which are searched out in the meter searching process are stored and then the addresses of all the energy meters are obtained. By means of the automatic energy meter address searching method, automatic energy meter address searching which is complete in meter searching and high in efficiency is realized, great convenience is brought to debugging and maintenance of electricity consumption information networks, and the meter searching efficiency is greatly improved.

Description

technical field [0001] The invention relates to the application field of power grid electric energy meters, in particular to a method for automatically searching electric energy meter addresses. Background technique [0002] To obtain the address of the electric energy meter, the traditional way is to manually record it. That is to say, no matter the electric energy meter is installed, replaced or removed, the electric energy meter list needs to be manually maintained. It is undoubtedly very troublesome to manually obtain the address of the electric energy meter. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a method for automatically searching the address of the electric energy meter. [0004] The purpose of the present invention is achieved like this: a kind of method for electric energy meter address automatic search is characterized in that: it comprises steps, [0005] A) Send the mete...
